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.

Based on my experience I have no hesitation recommending BCB Building Services who came recommended to me prior to this work by word of mouth. I needed to carry out modest renovation and remediation works on a newly purchased period property requiring many trades; general builder, scaffolder, plumber, plasterer, roofer, landscaper and damp specialist, etc. Brad and BCB team promptly provided a quote and, essential for me, agreed to source and project manage the diverse trades required to complete the work. They are busy but worth the patience and short wait necessary to get the work done by them. The workforce were professional, tidy, courteous and organised minimising disruption during the works and leaving the house clean and undamaged in their wake. The works were delivered per schedule and to a high standard and whilst not the cheapest, the pricing is fair and I believe the outcome represents tremendous value. Brad and the team remained pro-active beyond works completion and engaged actively in addressing the small amount of trivial snagging. They are now my go to for building works.

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.
