Pawel and his team are great - got them in for a few things now, from damp repair, knocking through an internal brick wall, moving a fuse box, installing a wood floor. Always good workmanship, easy comms and decent value! Have recommended to a few friends who are equally pleased.

Extensions- 5 Sep 2019
The builders did an incredible job refurbishing my house. For my house I wanted to break the internal wall to create a bigger living room and also for them to refurbish the toilet. In the beginning they’ve set a period when everything will be done and they’ve stuck to it so they are trustworthy. Seeing the progress, I could definitely tell that they were working incredibly hard and I know that they have been working long hours to ensure that they manage to finish it within the timeframe that they’ve set. I would definitely recommend them.

Peter was the on-site foreman on our complete house renovation, which took just over a year. This included an additional ensuite pod bedroom in the roof and a side-return and extension to the kitchen. Peter was totally reliable throughout the project and thoroughly professional. Throughout this time we were living in the house with the children. He was always on time, managed the on-site team well and communicated clearly with us. His workmanship is high quality and he was also a stickler for checking the work of others and getting it updated if it wasn’t up to scratch. I have no hesitation in recommending Peter.

Bricklaying- 25 Aug 2024
AVOID. Ernie incorrectly installed my drains under my house which has caused awful smells and sewage to leak under my house causing long term damage to my foundations Three professional drainage company’s have put a camera to see a Dropped pipe from new to old house. They have identified a connection that was never appropriate. Unfortunately, Ernie after being given many opportunities does not accept any responsibility. He is not an expert at all trades so be careful. I’ve asked him to help put right by exposing the floor which has Underfloor Heating. This has now cost me tens of £000s. My fault for not using a professional team at the beginning of my project.

Extensions- 3 Sep 2013
Kel and his team worked on my single storey extension with bifold doors and glass roof. He also did some landscaping in my garden, replacing the fencing and installing a raised patio with cedar battens to the side. Overall I was very pleased with the work Kel did. He is a good communicator and frequently visited the site to keep on top of the work. Kel was happy to discuss requests and was flexible with design changes. The bulk of the work was completed on time with just some minor snags remaining, but the finish is excellent. It's been a long and stressful journey, but it's been easier with the friendly support and professional approach Kel has taken to his job. I'd be happy to recommend Craft of London and provide a reference on request.
