What Affects Leak Repair Costs?

• 1. Leak location — An exposed pipe under the sink ($150–350) is cheapest. A slab leak ($500–4,000) or main line leak ($1,000–3,000) requires excavation and is far more expensive.
• 2. Detection method — Acoustic listening devices ($150–300), thermal imaging ($200–400), or video pipe inspection ($250–500) may be needed to find hidden leaks.
• 3. Pipe material — Copper and PEX are easier to repair. Galvanized steel (common in pre-1970 San Diego homes) often requires pipe replacement rather than spot repair.
• 4. Water damage — Repairing drywall, flooring, or structural damage from the leak adds $500–5,000+ beyond the pipe repair itself.

How to Save on Leak Repair

• ✓ Act fast — A small leak becomes a big repair quickly. Water damage compounds daily. Report leaks immediately.
• ✓ Check your insurance — Homeowners insurance often covers water damage (but not the pipe repair itself). Check your policy before paying out of pocket.
• ✓ Get multiple estimates — Leak repair pricing varies widely. Always get 3 quotes, especially for slab or underground leaks.
