Electric Water Heater Replacement in Greenbelt, MD

A homeowner in Greenbelt, Maryland contacted us after being told they had no hot water. When we arrived, we discovered the issue was more serious than a simple lack of hot water. Their electric water heater had been leaking for an extended period, and moisture had already led to mold buildup around the tank.


Our team drained approximately 50 gallons of water from the failing tank and completed an electric water heater replacement. We also upgraded the installation to meet current code-compliant standards, helping ensure the new water heater was installed safely and properly.

Before: Severe Corrosion & Hidden Leak Damage

Old metal plumbing corrodes over time, leading to rust, scale buildup, and silent leaks. As moisture accumulates behind walls and in subfloors, it creates ideal conditions for mold growth and structural decay. Left unchecked, minor corrosion can quickly turn into costly water damage repairs and unexpected pipe failures.
