White is our most popular colour and, as it is virgin uPVC with no lead, it will not discolour over time. White uPVC sash windows are easy to clean, low maintenance, and provides a fresh newly decorated look that doesn’t age with time.
Our coloured foils are perfect if you’re looking to replicate the traditional timber of original sash windows.
All colour foils are thermally bonded onto the uPVC extrusion to create a grained texture and provide an authentic aesthetic of timber. For a more natural wood effect, we recommend white woodgrain. We also offer foils in Cream, Golden Oak and Irish Oak. All can be applied to the sash windows internally and externally.
London Sash Windows also offer vibrant external colour options.
You can choose from Chartwell Green, Anthracite Grey, Rosewood, Black Brown, Cream, Golden Oak and Irish Oak. With this, you have the choice to maintain the natural white interior finish of your sash windows whilst injecting a dash of colour to the exterior of your London home.
You can opt for uPVC sash windows that feature bespoke astragal bar configurations.
Many authentic period sash windows feature decorative bar work that is raised on the surface of the window to create defining visual characteristics. London Sash Windows can configure the astragal bar in an array of designs to match, and compliment, the original style of the property.
We offer decorative horns as standard on our sash windows, with the additional option to add a ‘run-through’ horn.
Part of the unique sash window style that is popular throughout London is the decorative sash horns that provide an artistic flourish to the window. Our run-through sash horn replicates the aesthetic of an original timber box sash window, providing a continuous section of the frame which extends and can be shaped into a beautiful end piece.
Despite only the locks and tilt knobs being mandatory to include, we offer all furniture items in white as standard. Our non-standard selection of metallic finishes such as Gold, Chrome, and Brushed Chrome are available on all windows.
Sash window furniture delivers both practical and visual functions. Key operated twist locks provide security, whereas a pair of tilt knobs are required to operate the tilt. Other furniture items available are pole eyes, scroll lifts and travel restrictors.
Ogee architraves seamlessly blend the window to the surrounding walls, creating an overall aesthetic that is subtle but striking.
Most authentic period properties with sash windows in London would typically have a traditional picture framed interior finish as a decorative surround. Our Ogee architraves are able to retain this sash window style with a finish that enhances the period features of our uPVC sash windows.
Our sash windows comprise of contemporary manufacturing techniques as well as premium standard uPVC, allowing them to effortlessly capture the aesthetic of their traditional counterparts without carrying over any outdated or obsolete performance problems.

Perfect professionalism from first point of contact to cleaning up after work. Very consistent and thorough in communication. Prices are upfront and fair and most importantly - finished product is perfect. So happy I found them on Checkatrade and decided to solicit a quotation from them. Local London shops and nationwide leaders didn't measure up!
Three workmen carried the work out in just two days, friendly hard working. Douglas and Alastair very friendly and helpful salesmen - never pushy. Great family business - reliable and efficient from start to end.
Fantastic quality windows and very efficient installations. Installers (Mick, Chris, Terry and Jamie) were courteous, efficient and took time to explain details to me. The windows are great quality and ordering and contacting via Michael bending was seamless and easy. I was always kept informed and the process was transparent. Fantastic service and fully recommended!
AW installed secondary glazing for my box sash front windows, to schedule and on budget. The product uses acoustic glass and works very well to deaden noise from a busy road; the latch is simple to operate so that the front windows can be opened when required; and it's unobtrusive inside and out. They gave me a six week lead-in time and kept me informed by e-mail. The installers arrived on the day on time at 8 a.m. and completed the work in 90 minutes. Service was efficient and professional throughout from the first meeting with Doug the sales rep through to the installation. I didn't obtain alternative quotes but theirs seemed good value and matched my expectations. Overall it has been a smooth and stress-free experience and I would not hasten to recommend this excellent south-west London firm
Happy to recommend Alaskan to anyone looking to replace windows or for out a home - they’ve done a great job of replacing our 100yo original sash windows with a very elegant set of uPvc sash units. We were recommended Alaskan in the first place and they’ve been a pleasure to deal with. Michael firstly, with his understanding approach as we were looking at options. Nikki in the office who was always prompt to reply to our questions - and we had a few! And then Tony, who did a brilliant job with the install and finish. Very pleased with the Alaskan team, their products and service and have already recommended to neighbours.

The glass that makes up our sash windows can be upgraded to suit all homeowners. To deal with noise pollution we offer acoustic glass. Homeowners that are concerned with security can upgrade to laminated glass. We also offer a range of privacy glass such as frosted or the popular sandblasted effect.

The cavity where the boxes originally sat is filled with expanding insulating foam – with the additional option to add stone wall thermal insulation material into this cavity.

With this in mind, the measurement process is quick and simple for ensuring your windows fit your home correctly.
To determine the width and height of your window, measure the brickwork opening in 3 places for both the width and height required. Once completed, simply obtain your order size by choosing the smallest measurement from the 3 obtained, deducting approximately 10mm.
All height measurements must be from underneath any existing, removable sill. If your property is rendered, you will have to remove some render to measure the edge of the brickwork accurately. You’ll have your perfect sash windows size in no time at all.
