"We called to have our chimneys inspected because we had a bat in our home. Tim inspected both chimneys and the roof. He removed the caps and installed stainless steel screens over the flue opening on both fireplaces to help prevent bat intrusion through the flue. He did an excellent job. During his inspection, Tim noticed a hole in the b-vent chimney. Tim installed a new b-vent chimney from the basement to the roof. He connected it to the water heater and the furnace. There was no damage to our drywall which he had explained was a possibility during installation. They did an excellent job of cleaning up the debris and removing the existing pipe. We would highly recommend Top Shelf Chimneys."
