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
