How to Fix a Leaky Pipe (Temporary and Permanent)
For a temporary fix: turn off the water, dry the pipe, and apply a pipe repair clamp ($5-$15) or epoxy putty ($5-$10). For a permanent fix, the damaged section needs to be cut out and replaced — this costs $150-$500 for a plumber. Never leave a temporary fix in place long-term as it will eventually fail.
Cost Breakdown
| Service | Low | High | Notes |
|---|---|---|---|
| Pipe repair clamp (DIY) | $5 | $15 | Temporary, holds weeks |
| Epoxy putty (DIY) | $5 | $10 | Pinhole leaks only |
| Pipe repair tape (DIY) | $5 | $8 | Smallest leaks |
| Professional section repair | $150 | $500 | Permanent, cut + splice |
| Emergency plumber | $250 | $600 | After-hours premium |
Emergency Pipe Leak Fixes
Step 1: Stop the Water
Turn off the water supply. For a single fixture, use the shut-off valve under the sink or behind the toilet. For a pipe in the wall or basement, turn off the main shut-off valve. Open a faucet downstream to drain remaining water.
Temporary Fixes (Until the Plumber Arrives)
Pipe repair clamp ($5-$15): A metal sleeve with a rubber gasket that clamps around the leak. Available at any hardware store. Works on copper, PVC, and galvanized pipes. Can hold for weeks but is not permanent.
Epoxy putty ($5-$10): Knead the two-part putty and press it over the leak. Hardens in 20-30 minutes. Good for pinhole leaks and small cracks. Not for pressurized joints or large splits.
Pipe repair tape ($5-$8): Self-fusing silicone tape wrapped tightly around the leak. Best for very small leaks. Not as reliable as clamps or epoxy.
Rubber + hose clamp (free if you have them): Cut a piece of rubber (old inner tube, rubber glove) larger than the leak, wrap it around the pipe, and secure with hose clamps. Classic emergency fix.
Permanent Repairs
A plumber will cut out the damaged section and splice in new pipe. For copper, this means soldering new fittings. For PVC, gluing new sections. For PEX, crimp or push-fit fittings. Cost: $150-$500 depending on access and pipe type.
When Repair Is Not Enough
If you are getting leaks in multiple locations, the problem is systemic (corrosion, age, or defective pipe material). In this case, section repairs are throwing money away — whole-house repiping is the correct solution.

Related Questions
Can I use Flex Seal on a leaky pipe?
Flex Seal is not recommended for pressurized water pipes. It may slow a drip temporarily but will not hold under pressure. Use a proper pipe repair clamp or epoxy putty instead.
Is a small pipe leak an emergency?
A drip is not an immediate emergency but should be fixed soon — it will get worse and can cause mold, water damage, and structural problems. A spray or gush requires immediate shut-off and repair.
Does homeowners insurance cover pipe leaks?
Insurance typically covers sudden and accidental damage from a burst pipe but NOT the pipe repair itself or damage from gradual leaks. Document damage immediately with photos for your claim.
