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.

Felix did a fantastic job at upgrading my Consumer board or the fuse box and provided me with the EICR report at the end. I was apprehensive at first as I spoke to so many electricians and got so much info mixed up. Felix is very experienced and explained with clarity, which put my mind at ease. The job was honestly priced and within my budget. He is friendly and conscientious. Tidied after himself. I will definitely recommend.

Highly recommend Kris! He originally came to sand 15 of our steps, but he was doing such a great job that we asked him to complete the remaining 14 as well. Kris was reliable, punctual, and communicative throughout. He was also really flexible when we needed to pause the work for a few days to host guests, which we really appreciated. He gave us great advice along the way, and the stairs now look absolutely amazing. Thank you, Kris!

Harvinder from MBG Builders completely transformed my dated bathroom into a modern, well-designed space. He was professional, knowledgeable and offered smart layout and design ideas that made a real difference. The workmanship was excellent, with great attention to detail and the work area was kept clean throughout. Communication was clear from start to finish, the project stayed within budget. I’m very happy with the result and would highly recommend Harvinder and MBG

I recently hired Paul to repair the rotten and broken doors on my shed, and I couldn’t be happier with the results. The doors were in rough shape—warped, deteriorating, and barely functional—but he handled the job with real skill and attention to detail. He carefully removed the damaged wood, rebuilt the frames, and installed new panels that look sturdy and clean. The doors now open and close smoothly. He is professional & kept me updated throughout the process. Highly recommend his excellent craftsmanship

Placed advert Thursday. Contacted same day by Mike with a view to coming out and quoting next day. Came on time priced the job on Friday and arranged to start work on the Tuesday. Mike worked with his son Silas. What a really nice pair. Genuine, polite and got on with the job even though I asked for a few tweaks along the way. Both very old school and worked at their own pace - happy with work carried out and will use them again. Reasonable price too.

We had them in to install insulation in our upstairs floor, replace the sub floor, replace some lights, install a loft hatch, and board out our loft. On top of this they discovered a problem in our roof that they fixed. We were incredibly impressed by all of the staff that attended on site. They were friendly, polite at all times, and worked really hard, to a high standard. I couldn't recommend James and his team more, and we've already started talking to them about a further project.
