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!

Restoration & Refurbishment- 9 Sep 2021
The original job for a bathroom renovation turned into a much bigger job. Raphael and his team ended up helping design and renovate the bathroom, bedroom, living room and hallway. The team helped us source all the materials including underfloor heating and an incredibly intricate mosaic tiled floor in the hallway. They provided practical advise about what was best for the space, what would work within our budget and what would be easy to live with. For example, the team installed underfloor heating in the living room using wood effect herringbone ceramic tiles which would help get the maximum efficiency out of the underfloor heating whilst giving us the wooden flooring look we desired. Raphael and the team were excellent throughout delivering high quality work and we were more than happy with the final results. I would highly recommend Raph and his team.

What experience do you have with similar extensions in Waltham Forest?

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 Waltham Forest extension builder’s ability to deliver a result that meets your expectations.
