Extensions- 13 Feb 2022
Nick and his team did a brilliant job removing a wall, replastering a wall/ceiling and adding coving/skirting to make it look like it had always been like that. Nick went the extra mile when we came across a couple of unforeseen issues. The place was left clean and tidy each day (which was most appreciated). Great communication before/during the job. Highly recommended.

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.

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.

Conversions - General- 6 Feb 2023
Sorry this is long: our experience differs to most on here. We chose Better Living to do our side and rear extensions from start to finish. All was good until the subcontractors finished the main structures, then it all went downhill. Ben rarely answered his phone, texts, emails etc., and because they had started a bigger project elsewhere they repeatedly abandoned ours, often for weeks at a time. Even when we went on holiday, they had the complete run of the house for two weeks but did very little. Ben deliberately held up work for two weeks after receiving a stage payment a day late, having given us one day to pay after emailing an invoice. Beyond the main structural jobs their work was often sub-standard and our instructions were not followed due to poor communication between the team. Out of frustration we eventually took a lot of work off them and drafted in other tradesmen to complete the project, also doing some of the work ourselves. We have since had to have some of their heating work rectified by engineers. Not saying everything was bad, but fact is the list of problems and poorly completed jobs is too long to list here. They finished at our property over three months ago and have still not sent us the completion documents. As usual, Ben is not responding to our attempts to contact him. Despite being hospitable to their team, we feel we were treated shabbily by BL and sadly would not recommend them.
