What To Do When Your Outdoor Faucet Freezes and Leaks Indoors

Winter brings snow and beauty—but also frozen pipes. Outdoor faucets are especially vulnerable. When water inside a hose bib freezes, it expands. This can crack the pipe or faucet and cause water to leak indoors, damaging your home. Acting quickly is key. While waiting for a plumber, follow these steps to minimize damage and stay safe.

1. Shut Off the Water Immediately

The first step is stopping the water flow. Locate the valve controlling the outdoor faucet, usually inside near the pipe exit. Turn it clockwise until fully closed.

If you cannot find it, turn off your main water supply. This valve is often in the basement, crawlspace, or utility room near the water meter. Stop the flow, then move to the next step.

2. Locate the Correct Shut-Off Valve

Check the basement or crawlspace. Look for a lever or round handle. Turn the lever perpendicular to the pipe or rotate the handle clockwise to shut off water.

Newer homes may have a labeled manifold system showing valves for each area, including outdoor faucets. If unsure, consult your plumbing blueprint or call a professional. Knowing your valves saves crucial time in an emergency.

3. Contain Indoor Water Damage

After shutting off the water, stop leaks from spreading. Use towels, blankets, buckets, or a wet/dry vacuum to soak up water.

Move furniture and valuables away. Quick action reduces the risk of mold or structural damage.

4. Turn Off Power If Water Reaches Outlets

Check if water is near electrical outlets or appliances. If it is, turn off power to that area at your electrical panel.

If you’re unsure, call a licensed electrician. Safety comes first when water and electricity mix.

5. Thaw the Frozen Faucet Safely

Use a hairdryer on low heat to thaw the faucet and pipe. Wrap warm towels around the pipe if needed. Keep the faucet slightly open to let water expand as it thaws.

Never use open flames or high heat—they can damage pipes or cause fire.

6. Avoid Risky “Quick Fix” Hacks

Boiling water or blowtorches may seem fast but can crack pipes or start fires. Chemical de-icers can corrode pipes and harm the environment. Stick to safe, gradual thawing methods.

7. Recognize a Burst Hose Bib

Signs of a burst faucet include water stains, persistent dripping, increased water bills, damp walls, or mildew smell. Check for cracks in the pipe. When in doubt, call a plumber.

8. When to Shut Off the Main Water Line

If the outdoor faucet valve fails or water spreads, shut off the main water line. This protects the entire house.

Plan for essential water needs while the main supply is off, such as filling pots or buckets for drinking or cooking.

9. Document Damage for Insurance

Take photos and videos of affected areas. Record any immediate repairs. Contact your insurance company and provide detailed documentation—they may require it for claims.

10. Temporary DIY Fixes

Use pipe repair tape, rubber patches, or pipe caps to slow leaks. Place buckets under dripping pipes. These are temporary measures until a plumber arrives.

11. Communicate Clearly with Your Plumber

Provide the plumber with detailed information: when the leak started, steps you’ve taken, and any visible damage. Show photos or videos and share previous plumbing issues. Clear communication speeds up repairs.

12. Prevent Future Freezes

Install frost-proof outdoor faucets. Insulate pipes and faucets with foam covers or tape. Disconnect hoses during winter to avoid trapped water. Inspect pipes regularly and address damage immediately.

Winter plumbing emergencies are stressful, but acting fast and following safe steps can save your home from major water damage. Preparation and prevention are your best tools.
