SASH WINDOWS LONDON REVIEWS

Excellent experience with Sash Windows London for replacement of our traditional sash windows. Honest sound advice. Professional, knowledgeable and responsive from the outset through to fitting. Wouldn’t hesitate to recommend. Above all, very nice people to deal with at every stage. Excellent showroom in Clapham. I will be using them again in the near future for another property. Nice family run business.

Sash Windows London have been absolutely brilliant! We replaced all of our windows and doors in our flat and couldn’t be happier with the result. Ben, Danny and the installation team were all fantastic to work with - all super friendly and take great care in delivering the best possible product and service. Highly recommend!

The entire Sash Windows team were excellent from the initial discovery meeting right through to completion of our new windows and door. The quality of their work is great and I'd highly recommend this friendly and professional team. Thanks Sash Windows London!

SDG WINDOWS LTD REVIEWS

Everything was great from start to finish. Vic got me a quote quickly, which was very competitive. The team arrived on time and were very polite and respectful while I worked. They left everything clean and actually finished a bit earlier than expected. They changed 6 windows in a day, which look fantastic. I'm very happy I chose a local company. Highly recommended

Very impressed. Unfortunately, I'd been burgled and needed a new door and sidelight. Called a few companies and SDG could provide the door sooner than anyone else and they actually installed it earlier than promised. Great product. Great installation and brilliant communication.

Excellent communication with Vik and a great service. Delighted with our new windows at a very reasonable price. Care was taken to ensure the house was kept clean during installation as well which I really appreciated. Highly recommend

AYRTON WINDOWS & DOORS REVIEWS

We are THRILLED with the windows. I cannot believe the difference it has made to our house, both inside and out. The team were wonderful, extremely professional and hard working. They did a really good job of cleaning up - I'm sure my house was cleaner when they had gone than when they had started.

I am absolutely thrilled with the doors. They have transformed my kitchen and I know my lifestyle will improve immeasurably with the lovely sense of space and light they have brought. I’m particularly grateful for the professional help and advice I received at each stage of the process.

Service was brilliant. An added bonus was advice about how to maximise ventilation with sash windows (i.e.opening at top and bottom). From installation to after-care, Ayrton are faultless
