We had issues with our water heater exhaust vent and found out there were bunch of dead birds inside the pipes. Didn’t know who to contact but was told chimney related professional was needed. John reached out to us first and offered to come out very next day so we can resolve the issues. John was very honest and offered what needed to be done to prevent any animals getting inside of vent. Price was very reasonable and even offered lifetime warranty on newly installed roof vent cover. They installed high quality product where others offered that will last only few years. Overall, I’m very happy with results. I highly recommend John and his company.
