I've experienced lots of contractors over the years of being a homeowner and they can make you feel uncomfortable in your own home, NOT THIS ONE!!!! He was polite, friendly and very professional and knew exactly what he was doing and loved doing it, it's nice to know you can trust a contractor who is passionate about his work and explains anything and everything you want/need to know. I would 100% recommend him and know he would be able to answer any questions if I had a problem with the boiler and I would feel confident in the knowledge he knows what he's talking about. Bonus:- He doesn't charge silly amounts either!!!!
