Aluminium Bay and Bow Windows Installation, Repair & Replacement in South London & Surrey

Ask anyone who’s added a bay or bow window and they’ll tell you the same thing: the room feels completely different afterwards. It’s brighter, it feels bigger, and from the street the house looks like it’s had real thought put into it.

At Glitz Windows & Doors, we handle aluminium bay and bow windows installation, repair and replacement across South London and Surrey. These jobs are more involved than swapping a flat window, so we look at the structure first and the styling second.

Aluminium Bay and Bow Windows Installers You Can Rely On

Bay and bow windows have been popular for over a hundred years, and it’s easy to see why. You get extra light, a little extra floor space, and a feature that makes the front of your home stand out.

You might be adding a bay where there wasn’t one, replacing old timber that’s seen better days, or dealing with a problem on an existing frame. Either way, we look after the whole job, from the survey and manufacture through to fitting and aftercare.

What Are Aluminium Bay and Bow Windows?

Aluminium Bay Windows

A bay window pushes out from the wall in flat, angled panels, usually three: a central section with an angled side on each end. It's a favourite on period properties, and the extra depth is often enough for a window seat or a favourite armchair.

Aluminium Bow Windows

A bow window does a similar job, but the shape is a gentle curve made up of four or five equal panels. It feels softer than a bay and works well on contemporary homes as well as Victorian-style properties, depending on the detailing.

Why Choose Aluminium for Your Bay or Bow Window?

Slimmer frames, more daylight

Aluminium stays rigid without chunky profiles, so you get more glass and less frame. Across several panels, that makes a real difference to how bright the room feels. See our full range of Aluminium windows for other styles and finishes.

Strong enough for the job

A bay or bow carries more span and weight than a flat window. Aluminium is strong for its weight, so it holds its shape across bigger, heavier glazing.

No warping, rotting or corroding

These windows stick out from the wall and take weather from several directions. Aluminium doesn’t swell or rot, and the joints stay in good order for years.

Good for your heating bills

Thermally broken frames paired with double or triple glazing keep warmth inside. With this much glass, that matters more than it would on a standard window.

Kerb appeal that lasts

A well-proportioned bay or bow changes how your whole house looks from the road, and people notice.

Our Aluminium Bay and Bow Windows Services

Aluminium Bay and Bow Windows Installation

Every window is made to measure, and the right support goes in before the window does. We take care of the survey, manufacture, fitting and making good, and we'll tell you which Building Regulations route applies to your project.

Aluminium Bay and Bow Windows Replacement

If your current bay or bow is tired, replacing it can transform the room. Old timber can rot, warp and let in draughts, and early uPVC can discolour and lose its seals. We replace them with slim, efficient aluminium that suits your home, and we take extra care matching the look on Victorian and period properties.

Aluminium Bay and Bow Windows Repair

Not everything needs replacing. Misted double-glazing units, tired seals, stiff vents, faulty hardware and draughty frames can often be put right. We'll take a look and tell you honestly whether a repair makes sense. If we spot movement, sagging or damaged support, we'll flag it at the survey so it gets dealt with properly.

Why Choose Glitz Windows & Doors?

Local Service, Surrey & South London: We know the area and the kind of properties around here — from Victorian terraces with existing bay windows that need careful matching, to newer builds where you’re adding the feature from scratch.
Clear Quotes, No Pressure: You’ll get a proper written quote based on your actual property and structural requirements, not a rough verbal figure that changes once the work starts.

Quality Products & Aftercare: The window is only part of the job. Correct structural assessment, precise manufacturing and careful fitting are what actually determine whether your bay or bow window performs properly for decades, not just looks good on installation day.
Building Regs Compliance: Replacement and new bay or bow windows need to meet Building Regulations, and there are approved routes to demonstrate that. We’ll confirm which route applies to your installation and make sure it’s properly documented.

What Our Customers Says About Us

Residential & Commercial Aluminium Bay and Bow Windows

While bay and bow windows are most commonly associated with homes, particularly period and character properties, they’re also used in some commercial and hospitality settings where a striking frontage genuinely matters — cafes, boutique retail units, guesthouses. Whatever the setting, the same structural and design considerations apply, and we’re happy to talk through what’s involved at survey stage.

Aluminium Bay And Bow Windows FAQs

Do aluminium bay and bow windows need structural support?

Yes. They project outward and carry more weight and span than a flat window, so they need proper support such as a wall beneath, bracketing or reinforcement. We check this at survey, before the quote is finalised.

How much does aluminium bay and bow windows installation cost?

It depends on size, panel layout, glazing and any structural work. Book a free survey and we’ll give you an honest, itemised quote.

Do aluminium bay and bow windows suit period properties?

Very much so. With the right panel configuration and finish, aluminium bay and bow windows can suit period properties while offering better thermal performance and durability than the original timber frames ever did.
