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.

Living abroad presently, no regret having London Box Sash window replacing eight old windows with double glazed ones including two leaded windows. My initial contact, Jake, makes me at ease with the process. Judith who presented the quote, had it very well explained. Harry who is in charge of organising the actual work, upon inspection of my flat, gave me an initial details situation on potential problems i.e position of radiators, sink, gas meter etc, however worked around those problems with the engineer. Harry’s honesty was appreciated. The team of installers managed by Harry was equally good. My tenants are very happy with those new windows, they can feel the difference in temperature. From the video received, I am impressed with the end product. Would recommend London Box Sash Windows to friends and neighbours. London box sash window is a company you can trust.

It is my second time I am using London Box Sash Windows replacement service. I was first of all pleased to learn that the same people were still working in the company and it was a pleasure to deal with the team who I still remembered since my first interaction with the company few year back.The performance of the LBSW was outstanding from the beginning to the end, punctual, knowledgeable, friendly and very professional. Explained all options etc and the performance on the day was seamlessWould highly recommend with no reservations..

I am very satisfied with both the products and service provided by London Box Sash Windows. I was reassured by Murray’s knowledge and experience and he was helpful and patient when I was working out what I wanted. He listened, and there was no “hard sell”. Harry did the survey and Anjelo and Rafal the installation. They were all punctual and courteous. The installation was carried out quickly and efficiently, and Anjelo and Rafal took care with my property and tidied up after themselves. The aftersales care provided by Murray was excellent. Nothing seemed to be too much trouble. Having windows replaced is not a cheap option and involves a fair amount of upheaval, but I felt throughout the process that I could trust LBSW to provide value for money and make it as smooth as possible. I am very pleased with the end result. My new bay window looks great and is totally in keeping with the period of my property, including the “swept” heads. I immediately started to feel the benefits of having double-glazing in terms of heat retention, no draughts and noise reduction. I will also benefit from the improved security and low maintenance it offers. I would not hesitate to recommend London Box Sash Windows.

Fritha Hookway

So happy with the whole experience with London Box Sash. Our new windows look amazing. The whole process was very thorough, competitive in price and really quick for install – which was a nice surprise as the lead time was halved from what we’d thought it might be. The team were also exceptionally helpful when one of the old windows were were planning to replace was severely damaged during a storm. They came to board it up free of charge in the interim while the new one was still being built. Simon in particular was really helpful – a huge thank you to the whole team.

Joe Philp

A fantastic job. The end result is brilliant and a big improvement in terms of sound and thermal insulation. The team went above and beyond, taking time to understand our requirements and coming up with creative solutions. They were helpful and responsive throughout the process and the job was done quickly, carefully and meticulously – despite a last-minute adjustment that had to be made during the replacement. We felt in very safe hands and trusted the team completely – I wouldn’t hesitate to recommend.
