Firm charged me full $205 service fee for a 15 minute (if that) visit to determine my new batteries (I put them in myself) were just not making a connection! The service guy just rolled them around in the box - fixed - and left. Terribly disappointed.

Not sure what chimney repair services they actually provide. After an inspection where the people they sent snapped pictures, they pointed out the issues with our chimney, but stated that they do not perform this kind of repair work. They should indicate on their website what manor of repair work they can perform.

Beware of this company and it's estimates. If you decide to go with them make sure you know what you are getting yourself into and make sure your estimate includes everything you need with no ability to add additional costs unless approved by you. Otherwise, you will encounter high additional costs. To be fair the fireplace looks nice but the owner does not keep his word so put everything in writing , please! Apparently, he does not care about his business or reviews very much. If he did, he would not have a 2 1/2 stars Google rating.

Hey you guys have some pretty awful reviews here and on Yelp. Might you consider responding or addressing these? I am considering a visit to your shop.
