Germantown is dominated by 1980s-2000s subdivisions and townhouse clusters, so a lot of homes are now on their second water heater and deciding whether to repeat the same unit or move up in efficiency.
Availability changes through the day. Calling is the fastest way to get a real time window.

If the tank is leaking, shut the cold inlet valve on top of the unit and cut power or gas before you start moving anything.
If you smell gas, see sparking or cannot stop flooding, leave the property and call 911 and your utility provider first. Then call us.
Bring us the model number and the age of the unit and we can tell you on the phone whether a repair is even worth pricing.
