Kitchen Fitting- 9 Jul 2026
I hired Blend for a light house renovation. It started off really well then towards the end he ghosted me. No reason given. He didn’t answer phone calls or texts. There was no fight or disagreement. There is no decent reason why he shouldn’t communicate with a client. You can simply just say you have another job or you are not interested any longer. You don’t ask a client to buy stuff knowing you are not going to show up. It is an unacceptable and unprofessional behaviour. Because of this it’s cost me time that I can’t get back. But I guess it is what it is. I had to find another builder to complete the job. Some of which was not done properly. For example: my kitchen sink was leaking both inside and out. Had to buy a new toilet as something was broken while he was refitting it and etc. Pros: Blend is a nice and easy person to deal with. He is generally a nice guy. Tiling ✅ Cons: Finishing is not so great. could be a lot better. I also found patches and over paint on doors and others.

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.
