Bricklaying- 24 Apr 2019
Jake and Harry did an amazing job with our front wall and fence in the rear garden. We got three quotes for the job and they were the cheapest but also came across professionally. It wasn't a straight forward job, it was was using reclaimed materials that were varying size and shapes. I was also quite particular on the look, I wanted the brickwork to match our house, they took care to match the pointing and bricks but offered advice on how we could save money whist still getting the look we wanted. They arrived everyday on time, they were reliable, honest and extremely hardworking. They also kept us in the loop throughout the work making sure we were going to be happy with the end result. I have already recommended them to friends and will use them again for our next project. Thumbs up from us!

Kenny and team did a brilliant job replacing my old lean-to porch area for a new smart extension with windows, door and even a cat flap. They were on time, organised, efficient and took away all the old materials and rubbish. Kenny was helpful when he visited and prompt in replying to all communications and supplying quotes and invoices. I am very happy with their work and wouldn't hesitate to recommend their services.

Kitchen Fitting- 18 Nov 2025
Original timeline stretched a bit due to his other jobs but this was fine. Mario started work early and finished early which suited us. He came to visit and we agreed a price at the start and he stuck to it even when he realised some additional plumbing would be needed. He was honest about some accidental damage. Attention to detail is good and he has all the kit. I would have given 5 stars- he's a proper professional and I enjoyed working with him. 3 stars only because as soon as the work was done he became incommunicado (I messaged a week later to ask how to lift door which had dropped down a few mm on fridge). The warranty advertised is one of the reasons I went with MGB which was £200 more expensive than contenders so this was disappointing. I would have asked him to do my parents' new kitchen too otherwise.

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!

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.
