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 used Kingz for clearance of a very overgrown garden and new fencing. They did exactly what they said they would do in their quote. They worked hard, left the garden tidy, and took away all the waste. They were very pleasant and Emma, in particular, gave good advice regarding ongoing after care of the garden. We were very happy with the results and would definitely recommend this family team!

Avoid Wayne from Blackwell Roofing. He quoted £380 based on photos, then came to view the job from the ground—no proper inspection. He later climbed a ladder with no safety gear, started tearing down fascia, then suddenly claimed the job was £1,600. When I asked him to stop, he became aggressive, shouting and throwing tools and wood down dangerously. I felt threatened and unsafe in my own home. Totally unprofessional, dishonest, and intimidating. Do not hire him.

James and Andy provided excellent advice and did a great job. The job revealed some extra work was needed but the changes were all discussed and agreed without pressure before being implemented and James was able to bring in extra team members whilst on site so the work was completed in a timely fashion. All of the team were personable and a pleasure to have on site.

They called me to book in a job and moved the job time twice in the same day and felt it was appropriate to come out at 8pm at night. I'd wasted my whole Saturday waiting in for a quote. Ironic considering the name of their company.

Dan is a force of nature, as anyone who’s met him will agree. He and his team were always dedicated, hard-working and good natured. I would recommend Dan and his team to anyone, especially for a big renovation project like this, which involves working with other parties, such as structural engineers, kitchen designers and installers, as he works with them and takes away most of the pain. The quality of the work is excellent and he always came back to complete the snag list (even 3x for our thresholds).

I recently had Luke and his team widen an opening between two rooms in my property, which was a sizeable job requiring the installation of a steel beam. The work was managed efficiently, and great care was taken throughout the project. I’m very pleased with the results and would highly recommend Luke and his team for their professionalism and attention to detail.

Fired him for appalling work, no-shows and delays; see his other bad reviews. He's a middle man; does not do any work; got others to do it like a plumber, then a tiler the next day; slow work made worse when someone messed up or did not show up. Ali only shows to deliver materials or check work. Quick to reply when wanting the job. Slow/no response once job starts thinking you wont cancel. Materials I paid not returned; take every receipt and check you keep/use every item as he will even for wipes/tape
