What Are Quickslide Windows?
Quickslide is a British window manufacturer based in Brighouse, West Yorkshire, and the UK’s largest family-owned specialist in uPVC sliding sash windows, with over 20 years of manufacturing experience. Their flagship Legacy range replicates the look and proportions of traditional timber box sash windows in low-maintenance uPVC, built from Spectus profiles with a 37mm slim midrail, run-through sash horns, mechanical joints and a deep bottom rail that together make the window near-indistinguishable from an original. Both sashes slide vertically for ventilation and tilt inwards for easy cleaning from inside the home. The Legacy range is A-rated as standard and available in a wide range of heritage and contemporary styles. Every window is independently tested and the range is PAS 24 compliant, with Quickslide backing every product with a 10-year manufacturer’s guarantee.
Bowalker installs and replaces the full Quickslide Legacy range across Sussex and Surrey, including Victorian, Georgian, Edwardian and contemporary sash window styles, so the right design can be specified for each property without compromise.
The UK’s most authentic uPVC sash window
Quickslide’s Legacy is built with mechanical joints, a 37mm slim midrail, run-through horns and a deep bottom rail, the combination of details that makes a uPVC sash window look genuinely traditional rather than a modern imitation. Achieving U-values as low as 1.2 W/m²K without triple glazing means that conserving astragal bars and period detailing is never a trade-off against thermal performance.
Proven in conservation areas and listed buildings
The Legacy range has a strong track record of planning approval in conservation areas across the UK, and Quickslide provides technical support for planning applications. Sussex and Surrey have a high density of Victorian, Edwardian and Georgian properties where this matters.
Made in the UK, backed for 10 years
Every Legacy window is manufactured in-house at Quickslide’s Brighouse factory with full quality control, and each product carries a 10-year manufacturer’s guarantee.
No subcontractors, ever
Our own advisers, surveyors and installers quote and complete every job, so the people who specify your windows are the people who fit them.
Why Bowalker Installs Quickslide Windows?
We do not fit other companies’ products, and we do not install every brand we are asked to. We choose the systems we would be happy to put in our own homes, and Quickslide earns its place for a few clear reasons:
It is an approach our customers have rated ‘Excellent’ on Google and 9.9 on Checkatrade, and one we will not compromise on.
Quickslide Window Styles Available from Bowalker
Quickslide’s Legacy windows are all uPVC, all A-rated and all built to replicate traditional sliding sash windows, with a range of period styles so the design can match the age and character of your home.
The window styles Bowalker installs are:
Victorian
A six-over-six or two-over-two astragal bar layout replicating the most recognisable Victorian sash window configuration, with run-through horns, deep bottom rail and mechanical joints.
Georgian
A symmetrical multi-pane layout with thin glazing bars that replicate the traditional Georgian grid pattern, suited to late 18th and early 19th century properties.
Edwardian
A two-over-one configuration that reflects the lighter, more glazed aesthetic of the Edwardian era, with slim bars on the upper sash and a clear lower sash.
Flag and Arched
Bespoke configurations including arched heads for properties with original arched openings, manufactured to fit the aperture rather than compromising the architecture.
All styles are available with the 37mm slim midrail for maximum authenticity. Quickslide also manufactures casement and other window types where a project requires them alongside sash windows.
Colour and Finish Options Available
Because Quickslide’s windows are uPVC, colour is applied either as a foil bonded to the surface or as a factory-sprayed finish, meaning it will not fade, flake or need repainting. White is the most popular choice, and the range extends across 13 standard colourways in both smooth and woodgrain finishes, plus a full bespoke colour-matching service.
The finishes Bowalker can supply include:
White and Black
Smooth White and Black as classic single-colour options, suited to the full spectrum of property types from traditional to contemporary.
Woodgrain foils
Realistic timber-effect finishes including Cream Woodgrain, White Woodgrain, Irish Oak, Golden Oak and Rosewood, for properties where the warmth and appearance of wood is wanted without the maintenance.
Greys
Anthracite Grey, Agate Grey and French Grey in smooth or grained finishes, covering both contemporary and heritage-sympathetic specifications.
Heritage Tones
Chartwell Green and Cream for period properties where a softer, more traditional colour suits the architecture.
Dual Colour
Available across the range, including combinations such as Grey Woodgrain outside and Heritage White inside, letting the exterior and interior suit different design briefs.
Bespoke RAL colour-matching
Quickslide’s in-house colour-bonding service covers virtually any RAL shade for projects requiring a specific or unusual colour.
All 13 standard colourways are available on faster lead times, with bespoke RAL colour-bonding carrying a slightly longer turnaround. We will set out exactly where your chosen finish falls when we quote. Whichever you pick, we match it consistently across every window in the property.
Performance and Features of Quickslide Windows
Quickslide builds its Legacy windows to a genuine performance standard as well as an authentic visual one. A-rated double glazing, multi-chambered Spectus uPVC profiles and independently tested construction deliver energy efficiency, security and weather resistance without any of the visual compromise that triple glazing or non-period details would impose. The range is tested to Class 4 air permeability and Class 6A water tightness, and wind resistance up to 193 km/h, so the frames perform in the full range of British weather conditions.
Across the range, the features Bowalker can specify include:
- Warmth and lower bills: A-rated double-glazed units and multi-chambered uPVC frames achieve U-values between 1.2 and 1.4 W/m2K, keeping rooms warmer and heating bills lower.
- Authentic timber replication: 37mm slim midrail, run-through sash horns, mechanical joints, a deep bottom rail and no visible fixings combine to produce a window that passes as original timber even at close range.
- Quieter rooms: Double glazing significantly reduces traffic and street noise compared to single-glazed originals, a meaningful improvement for Victorian and Edwardian terraces on busy roads.
- Tilt-and-slide functionality: Both the top and bottom sashes slide for ventilation, and each sash tilts inwards for safe, easy cleaning of the outside face from inside the room.
- Tested security: PAS 24 upgrade available across the range, meeting the standard required for new builds, Part Q compliance and many home insurance policies. Optional Avia smart sash fasteners allow open and closed status to be monitored via smartphone.
- Conservation area suitability: The Legacy range has achieved planning approval in conservation areas across the UK. Quickslide provides technical support for planning applications where required.
- A choice of glass: Obscure and decorative options for bathrooms and privacy, alongside clear units and specialist heritage glass effects.
Replacing Your Windows with Quickslide
If your sash windows let in draughts, mist up between the panes or no longer run smoothly in their frames, replacing them is usually more cost-effective than repeated repairs or repainting cycles. The tell-tale signs that a sash window has reached the end of its working life include:
Bowalker replaces tired timber sash windows throughout the home with Quickslide’s Legacy range, matching the new frames to your property’s period character and planning requirements, including conservation area and listed building projects where authenticity is not optional. Every replacement is surveyed and fitted by our in-house team, and the old windows are removed and taken away on completion, leaving a warmer, quieter and more secure home that looks exactly as it should.
Draughts, or rooms that feel cold near the windows
Condensation or misting trapped between the panes of glass
Sashes that stick, drop or no longer stay open without a sash lift
Swollen, warped or rotten timber frames
Rattling in the wind or audible draughts around the sashes
Heating bills that keep creeping up
Warranty: Two Layers of Protection
New windows are a long-term investment, so it is worth knowing exactly who stands behind them. With Bowalker, you are covered on two fronts, the product and the fitting, by two separate guarantees.
In practice, both the manufacturer and the installer are accountable, and you have it in writing from each of them. It is the same cover we put behind every installation, and one of the reasons our customers return to us and recommend us years after the job is done.
Quickslide 10-year manufacturer’s guarantee
Quickslide guarantees every Legacy window against manufacturing defects for 10 years, covering the frame, hardware and sealed glazing units. This guarantee reflects the confidence Quickslide places in their in-house manufacturing and quality control.
Bowalker's 10-year installation guarantee
We guarantee our own workmanship for 10 years, and that guarantee is insurance-backed. An independent insurer underwrites it, so your cover stands even in the unlikely event we were no longer trading, a level of protection a verbal promise cannot match.
Real Installations: Before and After
The best measure of any window is the difference it makes on a real home, not in a brochure. The gallery below shows Quickslide installations our own team has carried out across Sussex and Surrey, the same homes before we started and after we had finished, so you can judge the change for yourself.
