Boris and his team came to me highly recommended by a neighbour. He offers a professional service, provides detailed, accurate quotes, and is clearly both knowledgeable and highly experienced and confident working on period, listed buildings. Boris is polite and courteous, and the job was completed to my full satisfaction. This was for repairs to sash windows in a listed mansion block. The windows are now draft free and I'm happy with the finish. I'm happy to recommend and would use again.

I employed the company to carry out renovation and replacement on 5 large sash windows in a 100 yr old converted flat in a conservation area. The men worked extremely hard & with skill on this demanding work. (Nothing is regular in this flat). When I asked for adjustments to the in situ secondary glazing, they readily agreed to carry this out. A really positive experience.

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.

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.

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.

boris came at the appointed time and gave me a competitive quote. he arrived on the agreed day and fully repaired and draught proofed my two bay windows. now for the first time in 12 years i have no draughts and my windows glide effortlessly up and down. finally, boris sealed it for me (excuse pun) when he cleared up, even using dustpan and brush on the outside sills. can't recommend highly enough.
