Do you need sliding sash window installation in Raynes Park, SW20

Raynes Park in southwest London features a mix of Edwardian and Victorian homes, many of which showcase period architectural details such as bay windows, decorative brickwork, and traditional sash windows.

Modern developments and contemporary apartments complement the historic properties, offering a diverse range of housing options. We can supply and fit sliding sash windows to suit all properties.

If your home’s sash windows fail, replacements could be the perfect solution. Draughty windows can cause heat loss and rising energy bills, but new, well-sealed sash windows significantly improve insulation. Double-glazed replacements also provide excellent soundproofing, reducing street noise and disturbances from neighbouring properties.

Condensation and moisture buildup on your windows may indicate poor insulation, potentially leading to mould – issues that replacement sash windows can resolve. Additionally, if your windows stick, are difficult to open or close, or have damaged frames or hardware, new sash windows can restore functionality while enhancing your home’s aesthetics.

I’ve had 4 windows done by London Box Sash Windows now and every time the entire process from quote to installation is so smooth and stress free that I never bother to contact anyone else.The final windows are great quality and beautiful to look at and the work is always done in the timeframe agreed with the installations always carried out by very friendly and professional people.

We are a returning customer of London box sash windows. Initially we went with them as they were the cheapest quotes however when we needed other windows to be replaced we didn’t approach any other company, we were so happy with the job they did the first time we wanted to use them again.I was fully informed about what to expect, given clear time scales and they were super helpful in providing information to support our planning application.There was a slight hiccup with the window not being quite right however this was resolved with no issue at all, another window was made and fitted within a few weeks.The fitters are really friendly, work hard and clean. They do an excellent job and I have no complaints what so ever!The whole service from start to finish has been really positive.

All round excellent service from start to finish. Polite, efficient, took care with other parts of the property and cleaned up better than I could have done. Not the cheapest but worth the investment.

Had a set of windows fitted in two rooms, replacing old single glazed windows with new double glazed sash windows. The new windows are a marked improvement and are keeping the house much warmer and better insulated all round. Very professional all round and easy to deal with on fitting timeframes – super speedy fitting too!

Thrilled with our 3 new box sash windows. The quality of the windows is excellent and worth every penny. I thought the price was very fair compared to other quotes I received given the quality of the wood that is used, the length of the guarantees and the ease of the company to deal with. The process from start to end has been seamless. Everyone we interacted with was superbly knowledgeable, responsive and helpful – from Harry, the sales person who helped explain all the design considerations and options very clearly, Judith in the office helping getting us booked in and Andy, the fitter. Andy consulted us on any bits where needed explaining clearly the decision that was needed and his work was to an excellent standard and he was very clean and tidy and respectful of our home. He also kindly made the suggestion to ask our decorator to angle the external sills as they were flat so that the water runs off which would help avoid any damp issues and improve longevity. His wealth of experience was very obvious and I was grateful for him sharing these pointers and discussing directly with my decorator – it’s something that would never have crossed my mind without his tip. I thoroughly recommend!
