More than 25 years of
glazing excellence
From a single van to London's most trusted glazing team — this is the UltraGlass story.
Built on craft, driven by results
UltraGlass was founded with a simple belief: that every home in London deserves to be warm, quiet and energy-efficient. Over the past 25 years, we've grown from a small local operation into one of the capital's most respected specialist glazing companies — but our values have never changed.
We work with homeowners, property developers, architects, conservation officers and housing associations across all London boroughs. Whether it's a single sash window in a Victorian terraced house or a full glazing programme for a new-build development, every project receives the same level of attention and care.
Our team of surveyors, fabricators and installation specialists are all directly employed by UltraGlass. We don't subcontract. We don't cut corners. We stand behind every installation with our comprehensive 10-year guarantee.

Our values aren't just words on a wall. They're the reason clients return to us again and again — and recommend us to their neighbours.
Craftsmanship
Every measurement, every cut, every fitting is held to a standard we'd be proud to show our families. Craft is not a buzzword — it's our daily practice.
Transparency
No hidden costs, no vague timelines and no hard sell. You'll receive a clear, detailed quote and a realistic project timeline from your first survey.
Reliability
We turn up when we say, finish on time and clean up fully before we leave. Your home is treated with the same respect as our own.
Quality
We only specify glazing units from Europe's leading manufacturers. If it doesn't meet our standard, it doesn't leave the workshop.
People First
Our clients are not project numbers. We take time to understand your home, your priorities and your budget before recommending a single thing.
Sustainability
Improving home energy efficiency is one of the most impactful environmental choices you can make. We're proud to play our part in reducing London's carbon footprint.
Specialists, not generalists
Glazing is all we do — and that focus shows in everything from our survey process to the final finish on your frames. We don't offer kitchens, conservatory builds or home extensions. We are, quite simply, the best at what we do.
Our surveying team brings together expertise in building physics, heritage conservation and modern glazing technology. This means we can advise correctly — whether you're a first-time buyer wanting to reduce your bills or an architect specifying glazing for a sensitive listed building project.
Every enquiry starts with a free, no-obligation survey at your property. There's no call centre, no automated quotes — just a real specialist who will listen, look and advise honestly.
