Sash window refurbishment 

Tomas refurbished and draught proofed 7 sash windows for me in November 2017. I am very happy with his work, his customer service is excellent and pricing reasonable and transparent. He is helpful, knowledgeable and reliable. I would definitely use him again. Recommended.

Tomas did a fantastic job. He was so quick. Got the window out and reassembled with new sash cord super efficiently. He's also a very pleasant and well mannered man. Will use him again to recondition other windows. I highly recommend him.
