Know Your Home's Vulnerable Areas
Every home has high-risk pipe locations. Walk through your home and identify: pipes running through exterior walls (feel the wall — if it's cold, pipes inside are at risk), pipes in the crawl space, garage plumbing (especially water heaters and supply lines), and any pipes in the attic. Mark these locations so you can quickly check them during cold snaps.
Insulation Options by Risk Level
Low risk (interior walls, heated rooms): No insulation needed. Medium risk (crawl space, basement): Foam pipe sleeves ($2-$5 per 6-foot section). High risk (exterior walls, garage): Electric heat tape with thermostat ($15-$30 per section) plus foam insulation over the tape. Critical risk (unheated areas in Foothills/Eagle): Self-regulating heat cable with insulation and pipe cover.
- ✓ Foam sleeves: Best for moderate protection in crawl spaces
- ✓ Heat tape: Self-activating when temps drop, ideal for exterior walls
- ✓ Pipe heating cable: Continuous protection for extreme cold zones
- ✓ Fiberglass wrap: Alternative for irregular pipe shapes
The Drip Strategy
Letting faucets drip during extreme cold isn't waste — it's insurance. Moving water resists freezing, and the open faucet relieves pressure so even if ice forms, the pipe won't burst. Focus on: the faucet furthest from the water heater, any faucet on an exterior wall, and the kitchen sink if it's against an outside wall. A slow, steady drip (about 5 drips per second) is sufficient.
Seasonal Checklist
October: Disconnect garden hoses, shut off outdoor supply valves, blow out irrigation system, install faucet covers. November: Insulate exposed pipes, install heat tape, test sump pump. December-March: Monitor weather forecasts, take extra precautions below 20°F. April: Inspect for freeze damage as weather warms.
Schedule professional winterization before October 15th.

Which pipes freeze first in Boise homes?
Outdoor faucets, pipes in crawl spaces, pipes in garage walls, and pipes in exterior walls — in that order. The Boise Foothills and Eagle homes at elevation are hit first.
Can PEX pipes freeze and burst?
PEX is more freeze-resistant than copper or galvanized — it expands up to 3x before bursting. However, it can still burst in severe freezes. PEX in exterior walls or crawl spaces should still be insulated.
How do I thaw a frozen pipe safely?
Open the faucet first. Apply gentle heat starting from the faucet end working toward the frozen section. Use a hair dryer, heating pad, or warm towels. Never use a torch or open flame.
