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.

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.
