 Trustindex verifies that the original source of the review is Google. Sandro was excellent and I can’t recommend him enough. He was communicative, fit me into his busy schedule without fuss, showed genuine care in helping me get my hot water up and running as soon as possible, did a thorough job checking potential leaks and charged very reasonably. I would highly recommend Sandro.
