Conversions - General- 29 Sep 2022
The job - gutting our living room. Tearing down the ceiling, removing all old wallpaper and ripping up the floor in order to insulate and add lighting. While we were doing this, we decided to replace the main steel in the living room (which was oversize and impacted the floor height in the guest room) and do remedial works in the guest room. The steel replacement was not time budgeted, but Oli and Tony didn’t hesitate to quote,To make time for us and bring in the structural engineer. Probably added 3 weeks to their time on site. The trades they brought in (plumbing for heating, electrician for downlighters, structural engineer and plasterers) were all professional, did an excellent job and were all unfailingly polite. It was easy to build a good, positive relationship with them, to the point we felt comfortable giving them the keys to the house so they could work while we went away for two weeks. They sent photos of their progress and showed up and worked as if we were there. I was very impressed by the state of the house when we got back. They watered our plants (I didn’t ask) and they cleaned the hallway so that it was spotless. They did a good job for a fair price, and were always cheerful and open to conversation. They came back to do a few snagging items without being chased (this is a huge thing for me, after having chased many builders to finish bits and pieces). I would definitely use them again.

Carpentry- 18 Aug 2025
Dennis gave a good quote, answered any questions I had, was understanding when the door was delivered damaged and had to put the job back a week. He arrived on time, he was clean and tidy in his work and made easy work of fitting our wheelchair access bathroom door (3ft wide). We are very happy with the finished result and will definitely go back to him if we need a carpenter in the future.

Kevin from K7 renovations has done 2 jobs for me in the last few years, the first being an annex in my garden, the second was a full extension with high vaulted ceilings. Both jobs ran smoothly from the time I handed him my architects drawings. The things that stood out for me were Kevin's knowledge and understanding of what I required, the timekeeping of everyone on site and last but not least the site was left tidy at the end of every day. I would highly recommend K7 to anyone. I would be happy to share photos of these projects with anyone.

Fencing- 23 Dec 2024
I highly recommend Alex and his company for their outstanding service following storm damage to our and neighbor fences. Alex arrived as scheduled and immediately got to work. His service was excellent throughout the process - he clearly explained what need to be done and kept us informed at every stage of the repair. What stood out most was his ability to complete all repairs within just one day. Despite the extensive wind damage, he worked efficiently without compromising on quality. The repaired sections of fence are sturdy and seamlessly match the existing structure. The pricing was reasonable and transparent, with no hidden cost or surprises on the final bill. He also thoroughly cleaned up the work area after completing the job. If you’re looking for reliable fencing specialist, I can confidently recommend Alex and his company.
