Beautiful sash windows for Streatham homes

Both salesman and surveyor were straightforward, helpful and answered all questions.Installers were very efficient, worked very hard, cleaning thoroughly.Astonishingly job completed in 6 hours.The only failing was forgetting to move a chest of drawers.Judith was friendly, very helpful and reassuring

We are delighted with our new windows. From our initial enquiry onwards everything was dealt with in a thoroughly professional, efficient and respectful way. A special mention of Andy, our fitter, whose craftsmanship and attention to detail was amazing.

Jake provided a great consultation and really listened to my requirements. He was confident, yet gentle with his approach and so knowledgable. I received multiple quotes from providers which honestly felt like a waste of time, as they didn’t seem to listen to my needs of wanting timber only. London Box Sash Windows stood out among them all, especially for their expertise and care in period properties. Really competitive pricing as well! Cannot wait to use and would highly recommend!

Can only recommend! Everything went extremely smoothly. The team were always available to answer any questions and walk us through the entire process to get our new window installed. Also very competitively priced.I will be reaching out to them soon to get other slash windows replaced.

Very efficient local team, first to book appointment and good contact from Judith in the office. Very thorough presentation from Jake and ability to offer a discount for speedy installation.Andy installed windows and he was professional & friendly. A very clean and methodical approach.They also have an after service care should anything happen which is very reassuring.I have already recommended them to two friends of mine.

I was very happy with the bespoke casement window they installed in my property. The company also agreed to repair it promptly after a number of years. London box sash install high quality timber windows and seem to care about their customers.

Needed a couple of old aluminium windows replaced with box sashes. Found recommendation for London Box Sash Windows Ltdon Which? Trusted Traders website (where they came top for our local area with over one hundred 5* reviews). Three days after the first phone contact, Jake came to our house to quote for the job. He took his time to take us through the various product options and even brought a sample sash window to demonstrate those options (all without any of the often quite annoying hard selling tactics). The quote price wasn’t cheap but within our expectations, and therefore we decided to go ahead with this company. We were given the option to either go for a scheduled installation date 10 to 12 weeks into the future or to go on a stand-by list. We opted for stand-by and a week later Harry (installation manager) visited to take the exact measurements for the window production and to reconfirm all the chosen options. About 2 weeks later, we were given an installation date.The actual installation was done by Andy over 2 days (1 day per window). On both days he started work at 7.30am, properly preparing the room with dust sheets and covering all carpets, before even touching his tools. He worked both days non stop until about 4pm. Andy was very pleasant to have in the house. He took the time to explain the details of the installation and patiently answered all of our many questions.The best, however, was the finished product. 2 gorgeous wooden box sash windows that are perfectly balanced, so that you can actually lift the solid and quite heavy sashes with just one finger!I wish that we had used London Box Sash Windows Ltdfor the replacement sash windows at the front of our house, a job which we had done about 6 years ago. Although those were of good quality, they are nowhere close to the ones that we had done just now.Without hesitation, I will recommend London Box Sash Windows Ltd to friends and neighbours and only keep quiet about this great company to the people I don’t like …

I have bought windows from London Box Sash twice now – the service is unmatched. Having had quotes from a series of other providers, LBSW kept coming out on top for me. The quality of the windows is extremely high, and they have made a massive difference to the feel of my home. The double glazing is excellent, and the installation was swift and professional. A huge thanks from a very happy repeat customer.
