Repair A Sash's quote was thorough and spelt out payment requirements, parking permits needed etc. We were having a sash bay window replaced. Their guy arrived at 8am every day and worked flat out until 4.30pm for five days. His work was very professional and the result is fantastic. Bit pricey but worth it.

I needed to have six sash windows restored and draught-proofed. Boris did a thorough survey, gave me good advice & provided a detailed quote. The work itself was carried out to the highest standard. Boris and his team were highly skilled, and also punctual, tidy and friendly.

We had 10 Edwardian sash windows and a balcony door that had been neglected and required some serious attention. We knew they were going to be expensive to refurbish but "Repair a Sash" gave us a fair quote and were flexible about timing. They did an excellent job in good time and the windows are now up to modern standards with no more rattles or drafts. They look beautiful too. We are very pleased with the job Boris and his boys did and are happy to recommend them.

We had two casement windows fitted. Boris was efficient, polite, used excellent quality windows and did a great job, offering to return if we had any problems. We thoroughly recommend him.

Boris has been reliable from my first telephone call to completion. He is very competent, works extremely hard to get things right, and will spend whatever time it takes to do the job properly and leave the place clean. His advice was sound and his quote the cheapest. The new sashes are solid, slide like a dream and the rooms are much warmer. I can't recommend him highly enough.
