Common questions
How do I know if I have a hidden leak?
Shut off every fixture and watch your water meter for 30 minutes. Movement means water is going somewhere it shouldn't.
Tank or tankless water heater?
Tankless costs 2–3x more installed but lasts about twice as long and cuts standby energy loss. Tank units make sense if you're staying under 5 years.
Is a permit required?
For water heater replacements, repipes, and sewer line work, almost always. An unpermitted job can complicate a future sale.
Things to watch out for
- Hourly quotes with no cap on an emergency job.
- Camera inspections used to sell a full sewer replacement without showing you the footage.
- Plumbers who won't pull permits for work that requires them.
