Craig got in touch quickly, gave me a rough estimate over the phone and answered all my questions. Surveyor arrived on time, gave instant quote. Price was good. Michael and (another) Craig turned up to do the job on the day, time given. Good, tidy job. Can't fault anything, from start to finish!! Would recommend!

George and his team are experienced builders, replaced my front door with a custom frame/sidelights and raising the floor level in the hallway quite quickly - in fact, they were the only who came next day, gave a quote straightaway and were ready to start in just couple of days. They also had all the necessary tools and materials, were ready to buy something additional quickly on the day - if further adjustments were required to fit everything as I asked. Thanks a lot for your help, guys!

Highly recommend. These guys did a fantastic job of constructing our pergola and decking. Very hardworking and reliable. The job was completed in the time frame agreed and to a very high standard. We would 100% use them again.

I cannot speak highly enough of the MBS team. They were everything one would expect from a service provider. They were punctual, polite, they knew what they were doing, the quality of workmanship was high, they were honest and their prices are fair. Most of all -they were reliable and clearly had our best interests at heart. I wouldn't hesitate to recommend them to any other prospective customers. Excellent!

I cannot recommend this company highly enough. Tudor & Darius did a brilliant job re-decorating my 2 bed flat, moving furniture around as needed without any fuss. They work quickly and meticulously neatly & cleanly. Tudor gave good advice on what type of paint to use on my woodwork, I didn't want it to look too shiny so chose eggshell. Whilst here they also sanded and re-hung my front door to prevent it from sticking. I would definitely use them again.

From start to finish, their professionalism, attention to detail, and commitment to customer satisfaction were truly commendable. They showed great technical expertise, able to get around a lot of obstacles which presented themselves during the cellar to bathroom conversion. I wholeheartedly recommend GBM homecare and Goia Construction, from their hardworking attitude to their courtesy and craftmanship. Thank you

They provided the materials and kept me informed in the process. They are hardworking and I saw a huge difference for every day they came.

I was apprehensive at first before making my first enquiries to get my job done as I haven’t done this kind of thing before. I was contacted by Nick at New Builds and he came to visit the site and explained everything to me in detail. The team at New Builds handled the job exceptionally well and kept me updated throughout the process. I was made aware of the costs all the way through which was helpful. I even needed some changes to the job which was handled just as well. I will be using them in the future.
