Tiling- 24 Sep 2025
I hired seasouth builds because not only did he give a really reasonable quote, but he also had knowledge of tiling over retrofit underfloor heating - which other tilers seemed to be really hesitant to work with. The job was done to an excellent standard - he’s a real perfectionist. It did take a bit longer than expected, due to some floor level issues which he didn’t account for when he quoted. I was really worried about the price increasing out of my budget when we started running over time, but I was so grateful to find that he was a really honest guy who stuck to the agreed quote and didn’t try to make it my problem one little bit. He was polite and friendly throughout the whole job, turned up whenever he said he would, and kept in constant contact. Really honest (I happily left him unattended in my property). Customer service was excellent, nothing was too much trouble. 10/10 would recommend.

Restoration & Refurbishment- 28 Dec 2015
I did quite a bit of research before choosing Battersea Builders. They didn’t come in with the cheapest quote but I never base my choice on price alone. And it wasn’t miles above the other quotes I got. Instead, I chose them because they ticked a lot of boxes including a) good independent reviews, b) a dedicated PM, c) qualifications, d) quick responses, e) a decent website etc. Overall, they did a fantastic job. The quality of the work and finish is really good. The PM, Tommy, was really helpful throughout and the team was very polite and conscientious. They were also on site every day as promised and didn’t play that old builders trick of getting the job and then going offsite to secure another job elsewhere (resulting in the deadline being missed). Was it perfect? No, but then not many projects are. I have a few minor comments including the fact there was a misunderstanding about the quality of bathroom cupboard I needed so the original quote was insufficient and costs had to be increased half way through the project. Despite this issue, Tommy did his best to keep the extra costs down. One other niggle was that I asked them to keep all the manuals and instructions for all the fittings but they threw them out. Not a big deal but quite annoying. Overall, it wasn’t cheap but I would use them again because the work was done to a high standard and the team were a pleasure to work with.
