Leak Repair in Longmeadow, ST 01106

“Thank you for your excellent and quick response. Mark and his co-worker worked diligently to resolve what I thought was a leaky hot water heater. They quickly realized that was not the problem and a series of malfunctions caused the water non the floor. Their investigation led to the need to replace the condensate pump – a simple and relatively inexpensive fix. Thanks to the monitor on my hot water heater the water on my cellar floor was detected and all was fixed in a very short time.”
