Most homeowners replace a water heater the morning after they discover a puddle in the basement. By that point, the decision is no longer “should I replace this?” — it’s “how fast can someone get here?” If you’d rather not be in that position, here’s what we look for, and what Frederick-area homeowners should know.
How long should a water heater last?
In Frederick County water:
- Tank water heaters (gas or electric): 8–12 years is normal. Hard water and never-flushed sediment shorten that.
- Tankless water heaters: 18–20 years with annual maintenance. Without maintenance, they scale up and lose efficiency long before that.
If yours is past 10 years and the tank is showing rust at the seams, plan for replacement before it forces the issue.
Warning signs we see most often
- Rusty hot water out of every tap. The cold side runs clear; the hot side is brown or yellow. That’s the inside of the tank rusting through.
- Pooling water under the unit. Even a slow weep is a tank failure in progress.
- Pop-pop-pop sounds during heating. Sediment buildup is making the burner work through a layer of crud at the bottom.
- Recovery time keeps getting longer. A tank that used to give an hour of hot showers now gives 20 minutes.
- Pilot won’t stay lit, even after a thermocouple replacement. Sometimes a sign of bad gas valve or sensor — sometimes a sign the unit is at end-of-life.
Tank or tankless?
We get this question on every replacement quote. Here’s the honest version:
Stay with a tank if: you have an existing gas line that won’t easily upsize, you’re on a tighter budget, or you have a household that uses hot water in big concentrated bursts (laundry + dishwasher + shower at the same time).
Switch to tankless if: you want to free up basement floor space, you want longer equipment life, you have natural gas with adequate line size, and you don’t run multiple high-flow fixtures simultaneously.
Both are good products. The wrong choice is whichever one was sold to you without anyone looking at your existing setup.
Frederick County permit requirements
Frederick County requires a permit for water heater replacement. We pull the permit, schedule the inspection, and handle the inspection visit as part of every install. If a contractor offers to skip the permit “to save money,” that’s a problem — both for you (insurance won’t cover unpermitted work) and for the contractor.
