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.

Tom Humphries and his team recently built our new porch & relayed our patio. Excellent quality work, reliable & very knowledgeable tradesmen. The porch has a vaulted ceiling with spot lights, shelving and very nice rounded brickwork steps up to the front door. The original patio had steps - it was dug out and re-layed to one level, in just a few days. Regular skips meant there was never any mess. The whole team went the extra mile so everything was perfect. Very pleased with everything. HIGHLY RECOMMENDED.

Clive and Andy have done a fantastic damp proofing job, totally reliable and a pleasure to have met. I have already spoken with my neighbours regarding them as I can absolutely recommend them and their work. They left everything so tidy as well, even cleaned their own tea cups! Can't praise them enough. An absolute refreshing experience to have found Clive and Andy, they are great! Harma & Steve N22

I really recommend working with Kilani. My job turned out to be much more complicated than expected. It required much more work to put right shoddy work from previous contractor. But Kilani was good to his word, sticking to original price he quoted and going above and beyond to turn what was a total disaster into a lovely useable room. He communicated well throughout the process and worked with consideration. Highly recommend.
