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.

Extensions- 7 Jun 2026
Zilvinas and the team at Innovate Builders were outstanding from start to finish. We hired them to build our two-storey side extension. Zilvinas was open, professional, and fully committed throughout the project. He was always available to answer questions, offer advice, and guide us through each stage of the build. His team worked hard and delivered a high-quality finish, all while keeping the project on schedule and within budget. As this was our first major building project, we relied heavily on Zilvinas's expertise and guidance. His knowledge, practical advice, and problem-solving skills were invaluable and made what could have been a stressful experience feel smooth and manageable. We are absolutely delighted with the result and would not hesitate to recommend Innovate Builder. As I said it was our first ever big project, we had heard many horror stories but are so grateful to have found Zilvinas and his team.

Groundwork & Foundations- 30 Aug 2022
Axel & his team have done a huge amount of work for us through 2022. They started by building the foundations, and then also built the block walls and the structure for the roof. They also constructed an entire extra timber framed shed. After more than four months of working for me constantly I can say that I'm very happy with the quality and speed of Axel's work. He has worked through all the work we have given him, and all the extra issues that came up, with a pragmatic and competent approach. The site today is unrecognisable from when he arrived (he also removed several tonnes of soil for us etc), and I would hire him again without reservation.

Painting & Decorating- 1 Jul 2017
I would highly recommend these guys. They did a very high quality job decorating my lounge, dining room, hallway and stairs. They started the job on time, worked through the weekend to get the job finished in good time, left the place clean and tidy at the end of every day, and cleaned up immaculately at the end of the job. The price was also very competitive compared with other quotes I received. I hope they are available again in a few months time when I have more decorating that needs to be done.

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.

Carpentry- 8 Apr 2026
I’m really happy with the work carried out. He came in to fix my steps after a previous builder had damaged them and left them unstable, and the difference is night and day. Everything now feels solid, secure and properly finished. He also fixed the skirting boards and installed my desk, all to a very high standard. What I really appreciated was how professional he was throughout and the advice he gave along the way, which showed real experience and care for the job. Overall, a really high-quality finish and a great attitude. I wouldn’t hesitate to recommend him.
