Extensions- 13 Oct 2023
KBL recently completed a side infill extension for us that involved a lot of complex hurdles (e.g., requiring special foundations because of a Thames Water waste pipe and steel beams). In hindsight, we were very lucky to have hired them because they made the whole experience stress-free by explaining everything to us and handling our neighbours, contractors, structural engineer and building control for us. The amount of digging in confined spaces and hard, physical labour they put into this job is amazing. The extension looks great, is solid, warm and watertight. The wetroom they built inside it hasn't had any problems - plumbing is working great. Their plastering quality is excellent. We had to live in the property during the 4 months of construction but we felt relaxed and 100% trusted KBL to respect and care for the house. They have a lot of experience, know the building regulations, use quality materials and methods, they answered all of our questions with patience and always responded to my phone calls + texts quickly. They're so good that we'll give them an additional job to do which we originally planned for in spring 2024. Everyone we know wants KBL's contact details and we definitely want to ask them back for future work.

Conversions - General- 15 Apr 2026
Luke and Diti are both amazing guys for this project. Honestly speaking they aren't the cheapest quote, but they are definitely beyond expectations. Luke was the only builder who gave a full transparent quote on each item and what was needed for the conversion. Really quick work and good planning because I have 2 cats and they did everything with enough people onsite to minimise the time. Speaking of work, it is good, we kept in communication and they were always happy to explain and adjust slightly according to my concern/question. Leave this comment after the work has been done for few months and everything is solid.

Decking- 31 May 2024
Firstly they came on time and job was finished on time, I would have given 4 1/2 stars overall. There was a couple of things I would have given 4 1/2 stars for and a mostly I would have given 5 stars. They was always on time every morning and was nice and polite. Overall I'm satisfied and looking forward to completing the rest myself. I had so many nice builders come to look and price the work, it was hard to choose. I am very happy with the outcome of the work.

Bathroom Fitting- 9 Feb 2019
Extremely pleased with the job Remi did. At the quoting stage he was upfront about costs we might not have considered, but still ended up being very competitive on price. During the job, he communicated clearly when he came up against issues; his fitting was to a high standard; he was on time and worked as long as he needed to each day to finish the job. His after-care was also good, as he returned to fix a related issue that arose during the work without quibbling; he also came back to complete fitting an item whose delivery had been delayed. Overall, I'd definitely hire him again.
