Walter was so kind and walked us through everything we needed to know about the current state of our fireplace and what we need to do to get it back in good order. Reasonably priced and quick scheduling!

Wonderful experience, with really knowledgeable staff. It was nice to have hired really knowledgeable capable crew to clean and add caps to my two fireplaces. We will be using them again next time for sure.
