We Come Highly Recommended!

SirVent was able to get us in on short notice so that we could get our fireplace up and running for the fall and winter season. They were right on time and did the job quickly without any mess or fuss.

The office staff is extremely friendly and took excellent care of me as well.

Affton was great to work with. I submitting a request for a quote and he replied immediately. He was able to schedule me in right away and even worked late at night to get me in before family arrived for Thanksgiving. He was thorough and clean and explained everything he saw without pressuring any fixes or upgrades. Definitely recommend.
