Extensions- 5 Feb 2019
I hired Chris and his team to do a complete refurb of my 3 bedroom house. I had a complete rewire of the property, plaster throughout walls and ceiling, new doors throughout, new floors, new pipework for downstairs which needed replacing, internal wall removed, new kitchen, windows and patio doors, utility room with downstairs toilet added and decorating throughout. It was a massive job and I am absolutely thrilled with my new house! Chris helped me choose suitable options to stick within my budget which was very helpful. He kept me updated every week with a financial spreadsheet to show what had been done and exactly where the costs had been allocated. The whole job took around 8 weeks and I was kept updated the whole way through the process. Quality of work was of a high standard and Chris, Bill and team were super friendly and happy to answer all my questions. I would highly recommend them and use them again myself for any other projects that I might have.

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
