Classic Aluminium Sliding Sash Windows Installed Across South London & Surrey

Aluminium sliding sash windows keep the look of a traditional sash without the problems. You get the familiar proportions and vertical opening, but none of the swelling, rot or repainting.

We supply and fit them across the area, and we’ll talk you through whether they suit your property before anything is agreed. No pressure, just honest advice.

What Are Aluminium Sliding Sash Windows?

A sliding sash window has two framed sections, called sashes, that slide vertically past each other inside the frame. You can open the top, the bottom or both, which is handy for controlling airflow without opening the whole window.

Traditional sashes are made of timber. They have real character, but they swell in winter, stick in summer and need repainting every few years to stop them rotting. Aluminium keeps the same look and proportions and removes all of that. You get smoother operation, no swelling, no rot and a finish that lasts for years. See our full range of Aluminium windows for other styles and finishes.

Why Choose Aluminium for Your Sliding Sash Window?

Traditional Look, Modern Performance

You get the classic vertical-sliding profile that suits period homes, without the weak insulation and security of an original timber sash.

Smooth, Reliable Operation

No sticking, no swelling shut after a wet week and no failed sash cords. Aluminium runs smoothly for years with very little upkeep.

Won't Warp, Rot or Corrode

Weather that would eventually rot or warp timber doesn’t affect aluminium. It holds its shape and finish through everything British weather throws at it.

Energy-Efficient by Design

Thermally broken aluminium frames with double or triple glazing cut the draughts and heat loss that single-glazed original sashes are known for.

Suits Conservation Areas and Period Properties

Sightlines and proportions can be matched closely to traditional timber sashes, so aluminium is often a realistic option where a home’s character needs protecting. Check your planning situation first, but it’s often more achievable than people expect.

Aluminium Sliding Sash Window Installation

As experienced sash window installers, we know that fit matters as much as the product. Every aluminium sliding sash window installation follows the same steps:

Free Home Survey & Quote

We visit, check your existing openings and talk through what's realistic for your property, including any conservation area points.

Made-to-Measure Manufacturing

Your windows are made to your exact measurements and, where it matters, to match the existing proportions of your home.

Professional Fitting

Our sash window fitters remove the old frames and fit the new ones, sealing everything properly so there are no draughts later. We protect your floors, keep mess down and clear up when we're done.

Aftercare & Guarantee

Your windows are covered by our guarantee on both the product and our workmanship. If something isn't right, we come back and sort it.

Aluminium Sash Window Replacement

If your timber sashes are rotting, sticking or letting in draughts, or your old uPVC has yellowed and lost its seals, aluminium sash window replacement is one of the best upgrades you can make. We remove the old frames, make good around the openings and leave you with windows that look right and perform far better.

You can replace a single window or the whole house, and we’ll keep the style consistent so everything looks right from the street.

Aluminium Sash Window Repair

You don’t always need new windows. If your aluminium sashes are structurally sound, aluminium sash window repair can be a much cheaper fix. We can usually sort:

Misted double-glazed units: we replace the sealed unit and keep your frame
Worn locks, stops and hardware: repaired or replaced so everything works and locks properly
Tired seals and draughts: new seals and adjustment for a tight close
Sticking or misaligned sashes: realigned so they slide smoothly again

If the frames are badly damaged or very old, we’ll tell you straight and talk you through replacement instead.

What Our Customers Says About Us

Residential & Commercial Aluminium Sliding Sash Windows

Sliding sash windows are most linked with period homes, but they’re also used in commercial and hospitality buildings where a traditional frontage matters, such as converted period buildings, boutique offices and guesthouses. The same design and performance points apply whatever the setting.

Aluminium Sliding Sash Windows FAQs

What is the difference between a sliding sash window and a casement window?

A sliding sash opens vertically, with two sashes sliding past each other. A casement is hinged at the side and swings outwards. Sashes are the traditional choice for period properties.

Are aluminium sliding sash windows suitable for period properties?

Generally, yes. The sightlines and proportions can be closely matched to traditional timber designs, which often makes them a realistic option even where a home’s character needs protecting. Check your specific planning requirements first.

Do aluminium sliding sash windows need much maintenance?

No, and that’s one of their main advantages over timber. An occasional wipe-down is all they need, with none of the repainting or repair that timber sashes demand.

How much do aluminium sliding sash windows cost?

It depends on the size, layout, glazing and finish. Get in touch for a free survey and an honest, itemised quote for your property.

Are aluminium sliding sash windows secure?

Yes. Multi-point locking and sash stops can be built in, which is a real step up from most original timber sashes.

Can you repair aluminium sash windows, or do they need replacing?

Often they can be repaired. Misted glass, worn hardware, tired seals and sticking sashes are all common fixes. If the frames are badly damaged, replacement may make more sense. We’ll take a look and give you an honest answer.
