Quantumfunding.io Reviews

They are all about secondary glazing, which means they install a second, independent window on the inside of your existing primary window.

This isn’t just about sticking a film on your glass. it’s a full-fledged structural enhancement.

Noise Reduction: Their primary selling point is cutting noise by up to 80%. This is a huge claim, especially for those living in bustling urban environments like London. Imagine the difference that makes to your peace of mind.
Thermal Insulation: Beyond noise, they tackle cold and draughts, promising significant reductions in heating consumption. This is a big win for both comfort and your wallet, particularly with rising energy costs.
Security & Aesthetics: They also mention improved security and eco-efficiency. Crucially, they emphasize that their unique design “mirrors the structure of your existing primary windows so that the secondary glazing is hardly visible once installed.” This addresses a common concern: will it look clunky or ruin the aesthetic?

Citysoundglazing.co.uk Features

City Sound Glazing isn’t just selling a product.

They’re selling a solution to common urban living problems.

Their features are built around high performance, aesthetic integration, and comprehensive customer service. Let’s break down what makes their offering tick. Mobilitysmart.co.uk Reviews

Noise Reduction Capabilities

This is arguably their strongest suit, especially for a company based in London. They claim “secondary glazing can reduce noise by up to 80%.” For anyone dealing with constant traffic, construction, or city hustle, this is a must. Imagine a quieter home or office where you can actually focus, relax, or sleep without constant disturbances.

Acoustic Insulation: The core mechanism is creating an air cavity between the primary and secondary windows, which acts as a sound buffer. Different glass types and cavity widths can optimize this effect.
Targeted Solution: They specifically mention environmental noise exclusion, making your space “noticeably more serene.” This isn’t just about dampening. it’s about creating an oasis.
Impact: A significant reduction in decibels translates to a vastly improved quality of life, potentially leading to better sleep, reduced stress, and increased productivity.

Thermal Insulation and Energy Efficiency

Beyond noise, the thermal benefits are substantial.

Old, single-glazed windows are notorious for energy loss.

City Sound Glazing positions secondary glazing as a cost-effective way to combat this.

Draught Exclusion: They promise “complete draught exclusion,” eliminating those uncomfortable cold spots that plague older properties.
Reduced Heating Consumption: By significantly improving insulation, properties become more thermally efficient, leading to “dramatically” lower heating bills. This is a tangible return on investment, especially during long British winters.
Environmental Benefits: Improved energy efficiency also translates to a smaller carbon footprint, aligning with modern sustainability goals. They note their units are manufactured from sustainable sources and are fully recyclable.

Customization and Aesthetic Integration

A major concern with any home improvement is how it will look. City Sound Glazing goes to great lengths to address this, emphasizing their “high performance, minimalistic secondary glazing.” Thelearningcottage.co.in Reviews

Hardly Visible: They state the units are “hardly visible” once fitted, designed to mirror the structure of existing primary windows. This is crucial for maintaining the architectural integrity of properties, especially heritage buildings.
Bespoke Design: Each unit is “uniquely designed and bespoke to our client,” ensuring a perfect fit and seamless integration with various window types, including:
- Victorian Sash windows
- Crittall windows
- Bay windows
- Picture windows
- Arched windows
- Casement windows
- Doors and unusually shaped windows
Reversible and Accessible: The secondary glazing is also “reversible and easily accessible for ventilation and cleaning,” adding to its practical utility without compromising aesthetics.

Security and Durability

While primarily focused on noise and thermal benefits, they also touch upon enhanced security.

The additional layer of glazing inherently adds another barrier against intruders.

Added Security Layer: An extra window unit makes forced entry more difficult and time-consuming, acting as a deterrent.
Durability and Guarantee: They offer a “12-year guarantee on all workmanship and materials,” backed by their nearly 60 years in business. This provides significant peace of mind, assuring customers that the company will be around to honor its commitments. Their long history is a testament to their product’s durability and their business’s stability.

Citysoundglazing.co.uk Pros & Cons

Alright, let’s break down the good, the bad, and what you need to consider when looking at City Sound Glazing.

Every service has its strengths and areas where it might not be the perfect fit for everyone.

Pros: What City Sound Glazing Nails

From a comprehensive review of their website and stated services, City Sound Glazing brings a lot to the table, especially for those looking for a premium, reliable solution. Emma-sleep.com Reviews

Decades of Experience Since 1968: This is perhaps their biggest selling point. Nearly 60 years in business translates to unparalleled expertise, established processes, and a deep understanding of the product. They’ve seen it all, done it all, and survived multiple economic cycles. This level of longevity is rare in the home improvement sector and inspires immense confidence. It’s like hiring a master craftsman who’s honed their skill over a lifetime.
Impressive Client Portfolio: Their list of recent assignments is genuinely eye-opening, featuring prestigious institutions like Eton College, eBay London Head Office, Shell-Mex House, Liberty London, and multiple universities and hospitals. This signals that they are trusted by high-stakes clients who demand meticulous quality and reliability. If they can handle the discerning requirements of these organizations, they’re likely equipped for complex residential projects too.
High-Performance and Minimalistic Design: They emphasize “highest performance, minimalistic secondary glazing,” which is crucial for modern aesthetics and preserving the look of period properties. The claim that units are “hardly visible once installed” is a significant advantage, as many worry about secondary glazing looking clunky or detracting from their home’s charm.
Significant Noise Reduction Up to 80%: For those in bustling urban environments, this is a massive benefit. Reducing noise pollution by such a substantial margin can drastically improve quality of life, sleep, and overall well-being.
Excellent Thermal Insulation: Beyond noise, their solutions address cold spots and draughts, promising “dramatic” reductions in heating consumption. This translates directly to tangible cost savings on energy bills, especially relevant in the current economic climate.
Strong Guarantee: A “12-year guarantee on all workmanship and materials” is a strong statement of confidence in their product and installation quality. Coupled with their long history, this ensures peace of mind for the customer regarding long-term reliability.
Bespoke and Versatile Solutions: They don’t offer a one-size-fits-all product. Their units are “uniquely designed and bespoke,” capable of working with “virtually every window type and shape,” including challenging Victorian Sash and Crittall windows. This flexibility is key for diverse property types.
Family-Run Ethos with Strong Customer Service: Being a family-run company “passed down through the generations” often means a deeper commitment to reputation and customer satisfaction. They explicitly state they “value customer service like no other” and have “impeccable after-sales service.”

Cons: What to Consider

While City Sound Glazing presents a strong case, there are always considerations to keep in mind, especially for certain types of customers or projects.

Likely Premium Pricing: Given their emphasis on “London’s Finest Boutique Secondary Glazing Company,” “high-end service,” and bespoke solutions, it’s highly probable that their pricing will be at the higher end of the market. This might not be suitable for those on a tight budget or looking for the cheapest option available. They are targeting “core clientèle are those seeking a high-end service with first-class products.”
Geographic Focus: While they “welcome enquiries for larger projects all over the country,” their “most of our work is focused within London and the M25.” This implies that customers outside this core area might experience longer lead times or higher travel costs for smaller residential projects. If you’re based far outside London, you might need to clarify their service radius and potential associated costs.
No Direct Online Pricing or Instant Quotes: The website does not provide any immediate pricing information, nor does it offer an online quote tool. This means potential customers must call for a “free quotation,” which, while personalized, requires an initial time commitment before getting any idea of cost. This might be a minor hurdle for those who prefer quick, preliminary estimates online.
Installation Requirement: Secondary glazing, by its nature, requires professional installation. This isn’t a DIY project. While this ensures quality, it means scheduling and coordinating with their team, which might not appeal to someone looking for a quick, self-installable solution.
Visibility, Even if Minimal: While they state it’s “hardly visible,” it’s still an additional window. For some, the mere presence of an internal frame, however slim, might be a consideration, particularly in properties with very specific aesthetic requirements or extremely narrow window recesses. This is subjective and depends on individual preference.

In summary, City Sound Glazing appears to be an excellent choice for those prioritizing quality, experience, and comprehensive service, especially in the London area, and who are prepared to invest in a premium solution for their noise and thermal insulation needs.

If budget is your absolute primary concern, or you’re outside their core service area, it’s worth exploring alternatives.

Citysoundglazing.co.uk Alternatives

When you’re looking into secondary glazing, City Sound Glazing clearly positions itself at the high end.

But what if you’re exploring other options, perhaps with a different budget or a broader geographic reach in mind? Or maybe you just want to compare features and see what else is out there. Dinbilpartner.dk Reviews

Here’s a look at some common alternatives, both within the secondary glazing market and other noise/thermal solutions.

Other Secondary Glazing Specialists

The market for secondary glazing is robust, with several reputable companies offering similar services.

The key differentiators often come down to pricing, specific product designs, lead times, and geographic coverage.

Magnetite UK: Known for their magnetic secondary glazing systems. These systems often offer a more DIY-friendly installation option compared to traditional framed units, though professional installation is still widely available. They focus heavily on thermal and acoustic benefits and can be a good alternative for those looking for a slightly less intrusive frame or a potential cost saving on installation if done by themselves.
Clearview Secondary Glazing: A prominent name in the UK market, Clearview offers a wide range of secondary glazing styles, including vertical sliders, horizontal sliders, fixed, and hinged units. They emphasize their custom-made solutions and have a national presence, which might appeal to those outside the M25 area. Their focus is on both heritage and modern properties.
Everest Secondary Glazing: While primarily known for their primary windows, Everest also offers secondary glazing solutions. They have a strong brand presence and widespread coverage across the UK. Their solutions often come with comprehensive guarantees, similar to their main window products.
Anglian Secondary Glazing: Another major national player in the window industry, Anglian provides secondary glazing as part of their broader product line. They offer bespoke solutions and professional installation, catering to a wide range of property types.

When comparing these, consider:

Customization options: How well can they match your existing windows?
Material quality: Are they using sustainable and durable materials?
Installation process: What’s their typical lead time and installation schedule?
Warranties and after-sales support: How do their guarantees stack up against City Sound Glazing’s 12-year offering?

Other Noise & Thermal Insulation Solutions

Sometimes, secondary glazing isn’t the only answer, or it might be part of a broader strategy. Tyred.io Reviews

Here are other methods people employ to tackle noise and thermal efficiency.

For Noise Reduction:

Heavy Curtains/Blinds: While not as effective as secondary glazing, thick, lined curtains can offer a minor degree of acoustic dampening by absorbing some sound waves. They are a much cheaper and simpler alternative.
Soundproof Plasterboard: For significant noise issues, especially between rooms or from external walls, adding soundproof plasterboard to walls can create a more substantial barrier. This is a more invasive and costly renovation.
Acoustic Paneling: In professional or home studio settings, acoustic panels can be installed on walls and ceilings to absorb sound and reduce echo. This is more about improving internal acoustics than blocking external noise.
Improved Door Seals: A surprising amount of noise can enter through gaps around doors. Installing draught excluders and better door seals can help.

For Thermal Insulation:

Double Glazing Upgrades: If your existing windows are old single-glazed units, upgrading to new double-glazed units might be an option. This is a more significant investment and alters the external appearance, which secondary glazing avoids.
Draught Proofing: Simple measures like sealing gaps around windows and doors with caulk, weatherstripping, or foam tape can significantly reduce heat loss. This is a cost-effective DIY solution.
Insulation Loft, Wall, Floor: Improving the overall insulation of your property loft, cavity walls, underfloor can drastically reduce heat loss and improve thermal comfort. This is a holistic approach to energy efficiency.
Heavy Curtains/Blinds again: Just like for noise, heavy, thermal-lined curtains can provide an extra layer of insulation, trapping heat inside the room.

Choosing an alternative depends on your specific needs, budget, and willingness to undertake different levels of renovation.

For a focused, effective, and minimally invasive solution for noise and thermal insulation, secondary glazing often remains a top contender, with City Sound Glazing representing a premium option within that category.

Citysoundglazing.co.uk Pricing

Understanding the pricing structure for a specialized service like secondary glazing can be tricky, especially when companies don’t provide instant online quotes.

Based on their website, City Sound Glazing clearly operates on a bespoke, quotation-based model, aligning with their positioning as a “boutique” and “high-end” service provider. Drsmile.nl Reviews

How Pricing is Determined

City Sound Glazing’s pricing is not transparently listed on their website, which is typical for custom-made, installed products. Instead, they require a “free quotation” for all inquiries. This approach is standard for services that involve:

Bespoke Manufacturing: Every secondary glazing unit is custom-made to fit specific window dimensions and types. There’s no one-size-fits-all product.
On-Site Assessment: The cost depends heavily on the complexity of the installation, the condition of existing windows, access to the property, and the specific requirements e.g., noise reduction level, thermal efficiency needs.
Material Selection: While they focus on high-performance materials, different glass types e.g., acoustic laminate, low-emissivity glass and frame finishes can influence the final price.
Volume and Project Scope: As evidenced by their commercial projects hotels, offices and trade supplier offerings, larger projects or trade discounts for supply-only orders will have different pricing structures than a single residential window. They explicitly offer trade clients a “40% discount on all enquiries” on a supply-only basis.

What to Expect During the Quotation Process

When you call for a quotation, you can expect the following:

Initial Consultation: A discussion about your needs, the issues you’re facing noise, cold, security, and the type of property.
Site Survey: For accurate pricing and measurement, they will likely conduct an on-site survey. This allows them to assess:
- The exact dimensions of each window.
- The type and condition of your existing primary windows e.g., sash, casement, bay.
- Any structural complexities or access challenges.
- Your aesthetic preferences and desired level of performance.
Detailed Proposal: Following the survey, they will provide a detailed, itemized quotation. This should include:
- Cost per unit.
- Installation fees.
- Any additional charges e.g., scaffolding if needed, disposal of old materials.
- The scope of work and estimated timeline.

Factors Influencing the Cost

While precise figures aren’t available, here are the key variables that will heavily influence your final bill:

Number of Windows: More windows naturally mean a higher cost.
Window Size and Type: Larger windows and more complex designs e.g., curved bay windows, very tall sash windows will be more expensive to manufacture and install.
Performance Requirements: If you need maximum noise reduction e.g., due to extreme external noise, this might require specialized acoustic glass, which costs more than standard glazing.
Frame Material and Finish: While they mention minimalistic design, there might be options for different frame materials or finishes that impact cost.
Installation Complexity: Ease of access, height of windows, and any need for specialized equipment like scaffolding will affect labor costs.
Location: While they focus on London and the M25, projects further afield might incur additional travel costs, though this would likely be for larger projects.

Is It an Investment?

Given their target market “high-end service with first-class products” and their extensive experience, City Sound Glazing’s pricing will likely reflect their premium positioning. This means you should view their service as an investment rather than a cheap fix.

Long-term Savings: The promise of “dramatically” reduced heating consumption means the initial outlay can be recouped over time through lower energy bills.
Increased Property Value: Improved energy efficiency, noise reduction, and enhanced security can add value to your property, making it more attractive to potential buyers.
Enhanced Comfort and Well-being: The intangible benefits of a quieter, warmer, and more comfortable home are significant and can justify the investment for many.

In essence, expect a personalized quote that reflects the quality, craftsmanship, and long-term benefits of City Sound Glazing’s solutions. Posterlounge.co.uk Reviews

Don’t expect bargain-basement prices, but rather a premium service designed for durability and performance.

Citysoundglazing.co.uk vs. Other Glazing Companies

When evaluating City Sound Glazing against competitors, it’s essential to look beyond just the product and consider the entire package: experience, quality, customer service, and target market.

City Sound Glazing has carved out a distinct niche, and understanding that niche is key to comparing them effectively.

City Sound Glazing’s Differentiators

City Sound Glazing sets itself apart through several key aspects:

Unmatched Longevity: Operating since 1968, their nearly 60 years of experience is a massive differentiator. Most competitors, even well-established ones, don’t have this depth of history. This implies a highly refined process, deep technical knowledge, and proven reliability.
- Data Point: “City Sound has been serving London’s community since 1968.”
Boutique and High-End Focus: They openly market themselves as “London’s Finest Boutique Secondary Glazing Company” targeting “high-end service with first-class products.” This suggests a commitment to superior craftsmanship, bespoke solutions, and meticulous attention to detail rather than high-volume, standardized installations.
Prestigious Client Portfolio: Their list of commercial and heritage projects Eton College, Liberty London, various universities is a strong testament to their capability to handle complex, demanding installations where aesthetics, precision, and durability are paramount. This separates them from companies primarily serving the residential mass market.
Strong Guarantee Backed by History: A “12-year guarantee on all workmanship and materials” is competitive. What makes it stronger is their long history: “Just remember, we have been here for almost 50 years – so you are assured we will be here for the next 12 years to honour our guarantee to you.” This is a powerful statement of financial stability and commitment.
Family-Run Ethos: Being a family-run company, passed down through generations, often correlates with a strong emphasis on reputation, personalized service, and a long-term view of customer relationships.

Comparison with Mass-Market Secondary Glazing Companies

Companies like Anglian, Everest, or local general window installers might offer secondary glazing. Here’s how City Sound Glazing likely stacks up: Peakycollectibles.co.uk Reviews

Pricing: City Sound Glazing will almost certainly be at a premium. Mass-market companies often aim for competitive pricing through economies of scale, standard product lines, and perhaps less bespoke manufacturing.
Customization: While larger companies offer options, City Sound Glazing’s focus on “uniquely designed and bespoke” units for “virtually every window type and shape” including challenging historical windows suggests a higher degree of customization and problem-solving for complex installations.
Service Level: A “boutique” company often means more personalized project management, direct communication, and a potentially more hands-on approach from start to finish. Larger companies, by necessity, might have more standardized customer service pipelines.
Installation Expertise: While large companies have trained installers, City Sound Glazing’s long history and high-profile client list suggest a deep specialization and particular expertise in secondary glazing, potentially leading to fewer issues during complex installations.

Comparison with Niche/Specialist Secondary Glazing Companies

Companies like Clearview or Magnetite also specialize in secondary glazing. The distinctions here become more subtle:

Product Design/System: Magnetite, for example, uses a magnetic system which can be different in aesthetics and installation process compared to City Sound Glazing’s framed units. Clearview offers a broad range of styles. City Sound Glazing emphasizes its “minimalistic” design that “mirrors the structure” of existing windows.
Geographic Reach: Some specialists might have a broader national reach than City Sound Glazing’s London and M25 primary focus, although City Sound Glazing does take larger projects nationally.
Target Market: While both are specialists, City Sound Glazing’s explicit “high-end” and “boutique” positioning indicates a clientele that values unparalleled quality and service above all else, often without as much price sensitivity. Other specialists might aim for a broader premium segment.

When to Choose City Sound Glazing

You would lean towards City Sound Glazing if:

You are in London or the M25 area.
You prioritize top-tier quality, precision, and bespoke solutions over budget.
You have a heritage property or complex window types that require expert handling and aesthetic preservation.
Noise reduction and thermal efficiency are critical concerns, and you want the most effective solution available.
You value a long-standing company with a proven track record and a strong guarantee.

In essence, City Sound Glazing positions itself as the specialist for those who want the best secondary glazing solution possible, delivered with expertise and tailored care, rather than a commodity product.

How to Get a Quote from Citysoundglazing.co.uk

So, if you’re serious about getting a secondary glazing solution from City Sound Glazing, the first step is picking up the phone.

Citysoundglazing.co.uk Guarantee and After-Sales Service

A company’s guarantee and its approach to after-sales service are critical indicators of its commitment to quality and customer satisfaction. Londonsafes.co.uk Reviews

City Sound Glazing emphasizes both, bolstering confidence in their long-term reliability.

The 12-Year Guarantee

City Sound Glazing offers a significant “12-year guarantee on all workmanship and materials.” This is a robust warranty for a home improvement product, indicating confidence in both the quality of their manufactured units and the skill of their installation teams.

Workmanship: This covers the installation process itself, ensuring that the secondary glazing is fitted correctly and professionally. If any issues arise due to faulty installation within this period, they are responsible for rectifying them.
Materials: This covers the integrity and performance of the secondary glazing units themselves, including the frames, glass, and seals. Should components fail or degrade prematurely due to manufacturing defects, they will replace or repair them.

What Makes Their Guarantee Stand Out

While a 12-year guarantee is strong on its own, City Sound Glazing adds a layer of reassurance that few competitors can match:

Backed by Longevity: They explicitly state, “Just remember, we have been here for almost 50 years – so you are assured we will be here for the next 12 years to honour our guarantee to you.” This is a powerful message. Many smaller or newer companies might offer long guarantees but lack the financial stability or proven track record to ensure they’ll still be around to fulfill them. City Sound Glazing’s nearly 60 years in business provides tangible proof of their enduring presence.
Trust and Stability: This longevity reduces the risk of the company disappearing or changing hands in a way that voids or complicates warranties. It speaks to a stable, reliable business operation.

After-Sales Service Commitment

Beyond the formal guarantee, City Sound Glazing highlights their commitment to “impeccable after-sales service.” This speaks to their ongoing support once the installation is complete.

Family-Run Ethos: Being a family-run business “passed down through the generations” often means a deeper personal investment in reputation and customer satisfaction. They state, “Very passionate about who we are, where we have come from and what we do, you can be assured of the highest level of expertise and service from us all.”
Customer-Centric Approach: They explicitly mention that they “value customer service like no other.” This suggests a proactive approach to addressing any concerns, questions, or minor adjustments that might be needed post-installation.
Troubleshooting and Support: Even with the best products, questions can arise e.g., cleaning, ventilation operation, seasonal adjustments. Good after-sales service ensures that customers have a point of contact for ongoing support.
Maintaining Performance: For a product designed for noise and thermal insulation, ensuring it continues to perform optimally over its lifespan requires proper care and occasional checks, which a good after-sales team can guide you through.

In summary, City Sound Glazing doesn’t just sell and install. B-id.co.uk Reviews

They back their products with a robust guarantee and a commitment to ongoing support.

Their decades of operation add significant weight to these promises, making them a trustworthy choice for a long-term home improvement investment.
