"Absolutely perfect service in every way. Thomas explained my options: my existing dryer vent could simply be cleaned out, or it could be improved: straighter path, safer materials. Replaced the whole vent, at my request. Disassembled and thoroughly cleaned out the inside of my dryer and the surrounding area of the basement. I happen to love data. Thomas measured the airflow to the outdoor end of the vent, before and after the whole process — and the airflow increased by 10 times! My clothes had been taking five hours to dry, and now they dry completely in just one hour. I couldn't be more satisfied."
