Recommended by friends, Bob came because the flames were too low. For so-called cleaning, adjusting etc., he charged me over $400.00 to tell me that the fireplace had a problem which he couldn't fix. At that point it would not even stay lit. He referred me to another company who charged me over $200 to tell me that the fireplace was unrepairable but that he might be able to get me a good price on a new one. I don't give up and I couldn't accept what they were telling me so I got another company who came and fixed it for around $200.
