Tiling- 3 Oct 2018
Goni and his team did a fantastic job. He came around to quote promptly, and the quote was competitive. The tiling itself was done to an exceptionally high stand with a precise eye for detail. He also did a couple of other extra jobs - fitting a doorstop, replacing a radiator so the tiling was perfect, and fitting a tiled upstand where the old skirting boards were. I am deeply impressed and have no hesitation in recommending Goni.

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.

Extensions- 24 Mar 2021
Rhys and his team have good skills and quality on all the extension works including big/long steel beam installation, extension connecting to the existing structure, complex loft conversion and architectural curve hung ceiling. For the internal decorating, they completed a beautiful bathroom for us. The staff were polite and friendly and also provided technical suggestions to optimise the design time to time. I would recommend RJB for similar size extension construction projects and decoration work.

I have been very happy with the work completed by Dragos and his team which included interior decoration and putting in a new bathroom. The work was done to a high standard, in a very professional manner. He had a plan and he stuck to it, working late when necessary, turning up on time and putting in a full day. I would have no hesitation in recommending Dragos and indeed intend to have him back to do further works in due course.

Extensions- 11 May 2016
Really happy with the work Paul and his team did on our extension. They were quick, neat and tidy throughout and kept us updated at each stage. There were some early design changes which building control insisted on and they were happy to adapt to the new plans without fuss. We couldn't believe how quickly it was all finished and the standard of work was very high too. Would definitely hire again if we ever need to.
