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!

Dmitry

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.

Unfortunately I’m dissatisfied with the job S&D has done for 3 reasons: * they smeared with the cement mix all the brickwork they touched as well as the adjacent wall and the electric car charger * they left the rubble behind * they were going to leave the roof not weather sealed until I spotted and and fought for it to be mended

John at Quebuild went above and beyond for us on this job. He completed all the work in a timely manner and for a very reasonable price. He was super knowledgeable and extremely attentive to detail, making sure to leave a high quality finish in terms of decoration - and he came back afterwards to address a few small things that needed doing. He was also a pleasure to have around - and I would highly recommend him for any other work. 10/10.

Had a window and front door fitted by Nation Windows. Overall the experience was good. The new fitting has made such a difference to our hallway. When they came to fit the window and door, Sunny and his fitters immediately put down dust sheets. We found them to do a clean job and were very polite throughout. Both Pam and Sunny were very helpful and friendly. They were true to there word to fix two minor issues after the fitting, So thank you.

James Butler also trades as CGS Landscapes. He paved my driveway with poor quality slabs in September 2024 blaming the manufacturer and not himself. More broken slabs has been replaced by him 3 times in 6 months. He has refused to respond to my calls. He texted back calling me. STUPID when I texted him to say I will report him to RatedPeople and the authorities. More slabs broke 2 days ago. Sent him the picture. He simply texted back: MOVED TO DEVON NO LONGER WORKING. Please don’t hire James Butler.
