Signs You Need Leak Repair
- Water stains on ceilings or walls
- Unexplained increase in water bill
- Musty odor or visible mold
- Sound of running water when fixtures are off
Is It Right For You?
Who It's For
- Homeowners with visible or suspected leaks
- Anyone with an unexplained water bill spike
Who It's Not For
- Major repiping projects (that is a repipe service, not leak repair)
- Brand-new construction still under builder warranty
What to Watch Out For
Diagnosis fees may apply even if you decline repair
Many plumbers credit the fee toward the work
Hidden leaks can expand scope
What starts as one fitting can reveal corroded pipe runs
Alternatives to Consider
| Alternative | Better When | Worse When |
|---|---|---|
| DIY pipe tape or epoxy | Works as a very short-term stopgap on accessible pinhole leaks | Fails quickly under pressure and can mask worsening damage |
| Whole-home repipe | Better when leaks are recurring across aging galvanized or polybutylene pipe | Overkill for a single isolated leak |
Is It Worth It?
For nearly all active leaks, professional repair is worth it. Water damage compounds daily, and repair cost is a fraction of remediation cost.
Questions to Ask Your Pro
- Is the diagnosis fee credited toward the repair?
- Is the repair warrantied, and for how long?
- Will you repair the wall/ceiling access opening?
