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.

Garden Maintenance- 10 Jul 2026
Ranj cleared my back garden, which was towering full of weeds/ nettles and our front drive. His is extremely good value for money. He removed all the garden waste too. I was so impressed with the work. Not one weed left behind. Everything was pristine. Excellent attention to detail. Super friendly service, super hard working and we were super pleased with how the back garden and front looked. Definitely recommend him.

What experience do you have with similar extensions in Kilburn?

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