Latest review:
Conor converted our loft space into a single dormer (bedroom and bathroom). Conor is a personable and reliable workman who is approachable and always had time to answer any questions or give updates on the project. My wife was heavily pregnant during our build and our eldest had just turned two years old. Conor was consistently mindful of the need to have times when there was quiet so as to get the kids asleep or times where he needed to work around our schedule. Overall, extremely happy with the quality and speed at which Conor worked. Chuffed with the final product. Have recommended him to numerous people.

Daniel is a hardworking, precise and clean worker. He worked tirelessly for a week, doing a fantastic job with everything we asked of him: we now have freshly painted walls, new carpets and a completely refurbished bathroom! He’s on time, polite, keeps noise to a minimum and he’s very pleasant to have a chat with too. I’ve already recommended him to my close circle very gladly.

The flat was left in a very bad state after the tenants left. Marius was able to undertake all the jobs, from changing carpets, redecorate, repairs and clean up. Also gave good advice as I was not able to attend the site in person so Marius kept me updated with photos. The price was also good. Thank you. Will use these guys again.

Extensions- 11 Nov 2019
I hired peter of quality first for a single story rear extension and total house refurb in a investment property. After much discussion and advice from peter regarding the costs and Added value, I decided to just do a house refurb, and I can truly say that peter’s input was sound and saved me a lot of time and money. I was able to leave peter and his guys to get on with the job and was extremely happy with the end result. I was kept up to date with progress on a daily Basis and Peter managed to keep close to budget by sourcing materials and appliances from his various reliable sources, sometimes travelling great distance in order to do so. I was so happy with the results that I have used Peter and his team for a much bigger project which is close to completion (on schedule) and will continue to use and recommend peter in the future.

Extensions- 25 Apr 2018
Initially when using My Builder, I didn’t really have any intentions of working with tradesmen from here, it was more to benchmark and see where a quotation would be priced however upon meeting Vijay, that pretty much changed from the first meeting. If you’re looking for someone who treats your project like their own, he’s the man. Vijay takes 110% pride and care into every aspect of your project. Although work is yet to commence on my property, the spec Vijay has put together itself is worth a lot of money, and most would consider it invaluable. From my opinion so far, no stone will be left unturned where Vijay’s project management and work is concerned. Without thinking twice, I would highly recommend anyone considering Vijay, to at the very least, meet with him and show him the work required. From there on, your mind will be made up. Looking forward to working with him in due course
