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.

Cannot recommend highly enough. The work was finished to a really high standard. They were really adaptable when the tiles we had ordered failed to arrive on time. They adjusted their plans and worked really hard to get the work done on time, without compromising on the quality of the finish. They were also really considerate of working around young children, and were very patient with little interruptions from a fascinated six year old!

Poor work. Chemfix wasn't mixed properly for gallows brackets and didn't set for over a week. The joiner didn't even know which joists required additional strength and I had to tell him what to do. Would not recommend.

They were really professional compared to the other builders that came and contacted me. The Project Manager was also on hand to answer any questions I had and offered me adviced on how best to move forward. We ended up refurbishing our entire bathroom which is looking great now. I would highly recommend London Builders.

From the start to finish could not fault the commitment shown by the builder, the quote came in under our budget and work was to a high standard. Always kept us informed on what was going on and when, tidied up as they went and we are more than happy with the final result.

Flavius is an excellent builder - and his team are quick, efficient and professional. Apart from that, I want to say as someone who was completely new to building projects, Flavius was extremely helpful in advising me (as I had no project manager/architect overseeing things) and made the whole process so much better. I am entirely delighted with the resulting space - it is a total transformation! - happy to recommend Flavius and his team to anyone. On time, on budget and an excellent result. 5 stars.

David, Adam and the team they employed were very good. They talked through every aspect of the job beforehand and made the costs clear in the contract. The construction was of a high quality and all done efficiently. This construction was completed during lockdown and the team adapted and communicated well throughout the process. Everyone who worked on the job was polite and friendly and professional. During the construction there were minor changes needed which were accomodated well, even after completion.

Stanley & his team originally came on board to build us a new rear extension which would house our kitchen as well as fit a new bathroom but as the project developed it ended up being near enough an entire house renovation and we're thrilled with the results. We still have work we would like to do to the outside of the house as well as a loft conversion and when we have enough money to take on those projects, we would definitely re-hire Stanley and his team. Highly recommend Stanley & his team.
