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.
