What Causes Frozen Pipes
Pipes freeze when water inside them is exposed to temperatures below 32°F for a sustained period. As water freezes it expands by about 9%, creating enormous pressure (up to 2,000 PSI) that can rupture any pipe material. The burst usually occurs between the ice blockage and a closed faucet.
Boise-specific factor: Boise averages 30-40 nights below freezing per winter, with occasional Arctic cold snaps dropping to single digits. The most vulnerable homes are those with pipes in exterior walls (common in older North End construction), uninsulated crawl spaces, and garages with exposed plumbing. The Boise Foothills see 10-15°F colder temperatures than the valley floor.
Signs You Have Frozen Pipes
Watch for these warning signs in your home:
- ✓ No water or very low flow from a faucet in cold weather
- ✓ Frost visible on an exposed pipe
- ✓ Unusual sounds (banging, clanking) from pipes
- ✓ Bulging or distorted pipe visible in crawl space
- ✓ Water damage appears after a cold snap when thawing begins
Can You Fix This Yourself?
If you suspect a frozen pipe: open the faucet to allow water to flow once thawing begins. Apply gentle heat with a hair dryer, heat lamp, or heating pad — never use an open flame. If you can't locate the frozen section or if the pipe has already burst, shut off the main water and call us.
If the problem persists or you're unsure, call a licensed plumber. Attempting complex repairs without proper tools can cause further damage and void warranties.
