Diligent, high quality and great value

Boris and his team have done a fantastic job replacing the sashes in 5 large windows in an industrial conversion within a conservation area. Right up front, Boris stood out during the scoping and estimating stage in terms of explaining what and how the work would be approached, properly considering special requirements that I had, and ensuring the detail was clear about what was / was not included in the estimate and at what cost. During the course of the sashes being installed, I found the precision with which the work was being done reassuring, resulting in a high quality fit and function. I can now actually open and close all of my windows easily, and the inclement UK weather in recent months has enabled me to verify that the draughts that have plagued me each winter since moving in have been addressed. This won't just reduce my energy bills, but create a much more stable and comfortable home environment. Even the finishing touches on fittings were handled with diligence, making sure that everything on the windows suited the aesthetic of the property. When raising an additional requirement to address the draughtproofing on a balcony door, I found Boris easy-to-approach, practical and there were no surprises in the final bill. Although the total time taken to finish the work has taken longer than hoped, this was primarily due to COVID and EU exit affecting manufacturing lead times and delivery. I would not hesitate to recommend Repair-a-Sash to others.

I would thoroughly recommend Repair a Sash if you need any replacement sash windows or a new front door. The new door Boris has made for us not only looks beautiful but it is really sturdy and secure. The team are tidy and work quickly to get the job done whilst on site. Boris always answered our questions in a patient and timely manner throughout the design phase. The whole process from start to finish was smooth and easy, and you can't ask for more than that.

Boris came to review our project and quote almost a year ago for the replacement of old aluminium windows for 8 new accoya sash windows (mix of weighted and balance sprung). He answered all our questions patiently and professionally, and was great at fitting us in when we were finally ready to do the work. I'd consider sash windows a luxury product, given the price point, and the service we received lived up to this. The quote was meticulous, and once on-site Boris was very good at keeping us informed of progress along the way. I wouldn't hesitate to recommend.

It was very satisfying to see our 7 sash windows gain a whole new lease of life through these repairs. The team were timely, the work is of good quality and the clearing-up/disruption are minimised. Repair A Sash were faithful to their quote and referred only one recommended change. Highly recommend their work.

I needed two of the original wooden casement windows replaced in my 1980's house, so they had to be made to measure. The quality was excellent (hardwood frames) and Boris adjusted the depth so that they fit in perfectly with minimal damage to the wall decorations. A great job.

As a landlord I really appreciated the fact I could rely on Boris to do a high quality job without lots of supervision. He did two separate jobs to a high standard and was flexible in the way he worked with the tenants which left everyone happy.
