Truth be told, most people don’t think about their windows and doors until something goes wrong — a draught sneaking in, a frame that’s seen better days, or maybe you’re just trying to make the house look a bit smarter. That’s usually where we come in. At London Glazing Ltd, we help homeowners, landlords, and even a fair few builders get the right double glazed windows, doors, and roof windows fitted without all the usual fuss.

Whether you’re after aluminium windows, uPVC doors, or a fully bespoke rooflight, we try to keep the process simple: good products, honest advice, and work that’s done properly the first time. London Glazing is a Double glazing Company at its best

Quality Glazing for Homes Across London

We’ve been around long enough to know that every home in London has its quirks. A Victorian terrace in East London? That’s one kind of challenge. A new-build flat in South London? Totally different. Our job is to match the product to the space — and sometimes to the personality of the homeowner too.

We supply and install:

• uPVC & Aluminium Windows (double or triple glazed)
• uPVC & Aluminium Doors (front doors, patio doors, bi-folds, sliders)
• Roof Windows & Skylights (Velux-style, fixed, opening, bespoke sizes)

Some folks only need supply only. Others prefer supply and fit. And we also do bespoke manufacturing, especially when someone says, “my opening is a strange size, can you still make it?” Usually… yes, we can.

Our Product Range

Most customers start by browsing a little, and it helps to see what’s available before deciding. Here’s a quick overview:

uPVC Windows

Low-maintenance, affordable, and energy-efficient. For most homes, they’re the sensible option.

Aluminium Windows

Slimmer frames, more glass, and a modern finish. Great for extensions, contemporary homes, or anyone who wants cleaner lines.

uPVC & Aluminium Doors

Front doors, French doors, sliding doors, and bi-folds. Each one has its own personality — and it really depends on the space and the look you’re going for.

Roof Windows / Rooflights

If you’ve ever stood in a room with a rooflight, you’ll know how different the light feels. It’s honestly one of the best home upgrades you can make.

Our Services:

Most people assume window companies all work the same way, but the truth is, the level of service can vary a lot. Here’s how we do it:

Supply Only

Ideal for builders, DIY installers, and trade customers who just need the product delivered.

Supply & Fit

Our most popular option — we measure, manufacture, deliver, and install everything.

Bespoke Manufacturing

For unusual openings, extensions, or custom architectural designs. If you’ve been told “that size isn’t standard,” don’t worry — we can usually sort it out.
