Client testimonials

Natasha, Maida Vale


"I used Envirosash to make 6 new sashes as well as an entirely new sash window. The windows are of the highest quality, beautifully made and draught-proofed. They keep the flat much warmer and we've already noticed how much quieter it is. Alex was competitive on price even taking into account the quality materials that he uses. I wouldn't hestitate to recommend Envirosash on the basis of their craftsmanship, reliability and general ease with which they performed the job."

Mervyn, Crouch End


"Alex was a pleasure to deal with and the job was done on time and as expected. His workforce did a high quality job and were always polite, helpful and attentive. They also made sure to clean up at the end of each day. We had most of the windows in the house replaced and it has made a real difference. Happy to recommend."

Sarah, Gravesend


"Had some replacement slim double glazed sashes fitted recently. Good craftsmanship and thorough job. Cleaned up every evening. Good to have a quote from someone who actually understands the work to be done, rather than from someone who is just a salesman. Would definitely recommend."
