Frequently Asked Questions - Drain Line Leaks

Q: What causes drain line leaks?
A: Common causes include corrosion, root intrusion, poor installation, clogs that create pressure, or age-related pipe failure.

Q: How can I tell if the leak is from a drain line and not a supply line?
A: Drain leaks often appear after using sinks, tubs, or laundry — especially if the water has a musty odor or occurs intermittently.

Q: Will you have to open walls or floors?
A: Only if necessary. We use advanced leak detection tools to minimize demolition and target repairs precisely.

Q: Are drain line repairs covered by homeowners insurance?
A: Sometimes. If the damage is sudden and accidental (not due to neglect), your policy may cover part of the repair. We can help document the issue for your claim.
​
Q: How long does the repair process take?
A: Most minor leaks are fixed within a day. Larger or concealed leaks may take 2–3 days depending on the damage.
