Repair or replace?
We'll tell you honestly.
Repair vs. replacement
The honest answer depends on age, condition, and what failed.
Under 10 years
Usually repairAn isolated failure — element, thermostat, T&P valve — is almost always worth repairing. The tank has life left.
10–15 years, recurring issues
Often replaceRepair might buy another year or two, but replacement is the smarter long-term investment.
Tank body leaking
ReplaceInternal corrosion — replacement is the only real fix. We can handle installation the same visit.
Signs you need a repair
Don't wait until you've fully lost hot water.
- No hot water, or not getting hot enough
- Hot water runs out faster than it used to
- Rusty, discolored, or cloudy hot water
- Water pooling at the base of the tank
- Popping, rumbling, or banging from the unit
- Pilot light keeps going out (gas units)
- Unusually high gas or electric bills
FAQ
Common questions
Everything homeowners ask before calling us.
Most repairs run $150–$400 depending on the part and labor. A failed heating element or thermostat is typically on the lower end. We give you a price before any work begins — no surprises.
Most repairs are done in 1–2 hours. Element and thermostat replacements are usually under 90 minutes. If we need to order a part, we schedule a return visit and give you a timeline — you won't be left guessing.
Depends where the leak is. A fitting, T&P valve, or drain valve is usually a straightforward fix. A leak from the tank body means internal corrosion — that requires replacement. We'll tell you which situation you're in after the inspection.
Under 10 years old with an isolated failure — element, thermostat, T&P valve — repair is almost always the better value. 12–15 years old with recurring problems, or a leaking tank body, and replacement makes more sense long-term. We give you the honest answer.

Customer Reviews
Don't take our
word for it.
“I recently called another plumbing company who quoted $350 labor & $150+ for parts — then said they'd call me when they found the part. Guerra Bros came out within 30 mins, checked out my issue, and fixed it under an hour for $237. Now I have hot water again.”
“I highly recommend Guerra plumbing. Tony was professional, knowledgeable and solved all of the plumbing issues. He explained the causes of the problems and offered suggestions for prevention.”
“Guerra Bros. Plumbing came out same day and fixed our leak quickly. Honest pricing and professional service. Highly recommend!”
