Be smart! Learn from me! Expect to be ripped off by this company. Expect a proper breakdown of charges, parts and labour and do your research, and get other quotes. This is a very expensive service that I will never use again.
I can't say they have particularly good work either as our pressure valve was leaking and caused us a lot of inconvenience. It was fixed - they are polite but charge way VERY high rates. My advice. GO ELSEWHERE !!!!!
