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.

We hired Cani Building Services to replace the front stairs and pathway of our Victorian home with granite pavers in the spring of 2025. When evaluating the builders it was important to us that we found somebody who was professional, reliable, and detail-oriented. Durim offered a competitive quote and promptly started work. ?He completed our job to a high level of quality within a week’s time, and we are very pleased with the outcome. We would absolutely recommend his services to others!

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

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 More broken slabs has been replaced by him 3 times in 6 months.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.

Absolutely thrilled with our new shower! Amir was fantastic—professional, friendly, and nothing was ever too much trouble. We had a radiator changed, another one removed, a boil tap installed, and our bath taken out and replaced with a sleek new shower. Amir and his team were brilliant throughout, keeping everything tidy and treating our home with great care.
