Tiling- 16 Feb 2026
Luis did an excellent job on my bathroom. He had to do a lot of prep work before starting the tiling, including rebuilding the floor and repairing the walls. At every stage he explained what needed to be done, ensured that I wanted to go ahead, listed the materials that would be needed, and the cost. It made a huge different to me that Luis was willing to source and purchase all materials; he checked in with me from the suppliers as to choice and cost, and sent receipts for every penny. I cannot recommend him highly enough, for his knowledge and expertise, his honesty and hard work, and also for being such a lovely person, nothing is too much trouble. I am delighted with my new bathroom, and am planning more home improvements with Luis, when he is free again!

Carpentry- 14 May 2026
Replaced a rotten external single door. The existing door frame was reused, as per request. This frame wasn't perfectly square which Alex had to compensate for. Alex arrived on time and completed the work without any unresolved issues, taking all offcuts and old door away for disposal.

What experience do you have with similar extensions in Bayswater?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Bayswater extension builder’s ability to deliver a result that meets your expectations.
