"Krystain was the most responsible to my initial enquiry. I sent 4 requests and the 3 others did not reply to me when they realised it was a smallish job. I had never used Checkatrade before. While straightforward the job was done to a high standard. Equally important Krystain was extremely polite and no point did I think he would charge me an excessive price. His fee was agreed in advance. This is very important for me and as a result I will use him for any jobs in the future."

We contracted Krystian who goes by the company name Comfort Zone to fit our boiler that went well. We then gave him th job of fitting out underfloor heating that was much more expensive but quoted over text messages so I ended up confused and paying much more than what I expected. After delivery a couple of problems arose including a leak in the system. Krystian promised on several occasions to attend to make remedial problems but three months after making initial contact he is yet to turn up and no longer replies to messages or answers calls. A reference he gave me is also having trouble.

My husband contacted the tradesperson about water softener treatment and his availability. He told us he could do the job and agreed on week beginning 2nd June. He told us what products to buy only not to respond to his messages again. My husband sent him 3 messages to ask again when he was coming over to complete the job and he ignored them all. The most dishonest and unreliable tradesperson I have ever come across.
