Bethesda has a high share of renovated and expanded homes, which means hot water demand frequently outgrew the original system long before the system failed.
Availability changes through the day. Calling is the fastest way to get a real time window.

If a unit in a finished space fails, shut the cold inlet and cut power or gas before moving anything out of the water.
If you smell gas, see sparking or cannot stop flooding, leave the property and call 911 and your utility provider first. Then call us.
If you run out of hot water regularly, replacing like-for-like will reproduce the problem. We size for actual peak demand instead.
