Extensions- 31 Jul 2015
Kamil and team have been an absolute joy and a pleasure to work with during the construction of our kitchen extension. They are incredibly hard working, every morning 7.30am starts and when needed working weekends as well. Every little extra we have asked for has been no problem at all, solutions have been found to everything. Not only have they built the extension but made sensible and welcome suggestions to how things could be done differently for a better effect -e.g the lighting, sockets, boiler set up. All work is completed to the highest standards and cleaned up afterwards. I would have no hesitation in recommending them to anyone, we have already employed them to overhaul the shower and heating in the rest of the house later in the year. 5 STARS

Extensions- 11 May 2018
After a rogue builder left me with 18 (eighteen) structural issues. Lez and his crew came in transformed my failed extension into a masterpiece. All aspects of the job was done to the highest quality and utmost care and attention to detail was shown to building control needs. They cleaned up after every day and made sure the house was habitable, as I had to live there. Every aspect of the build, from the carpentry, plastering and tiling was first class and their recommend electrician and plumbers were from the same stock. Total professionals. My only regret is that I did not use this builder the first time. The prices were reasonable and even building control had good word to say about their work. Thanks Lez

Loft Conversion- 23 Nov 2021
We instructed Masterbuild & Maintenance to undertake a loft conversion and side extension to our bungalow in the spring of 2021. Dan and his team worked tirelessly to ensure that we were happy with every stage of the build and it was never too much for any of them to make modifications to get the desired result. They were hardworking, diligent and genuinely cared about their work which shows in the quality of their workmanship and the various trades employed. Dan’s team worked well together and were on-site every day for the 6 month build. We thoroughly enjoyed working with them on the project and can honestly say that we couldn’t have imagined any other builders doing the work. We are over the moon with the end result and receive so many wonderful comments from people about the job. We would absolutely recommend Dan and his team to undertake any building project and cannot commend their work highly enough.
