- Pipes on exterior walls in kitchens and bathrooms — particularly in additions — are the highest-risk locations in North Shore homes.
- Letting a cold-side faucet drip during sub-zero nights keeps water moving and dramatically reduces freeze risk.
- If you suspect a frozen pipe but it hasn't burst yet, do not attempt to thaw it with an open flame — call Legendary for safe thawing procedures.
Before the first sustained below-zero cold snap of the season
Proactive prevention — foam insulation on exposed lines, heat tape on vulnerable runs, and cabinet doors open under kitchen sinks on exterior walls — costs very little compared to a burst pipe and resulting water damage.
After discovering no flow at a fixture during cold weather
No flow at a single fixture during a cold snap typically means a frozen supply line to that fixture. Turn off the home's main shut-off before attempting to thaw and call Legendary — the pipe may already be cracked and will release water when thawed.
Where pipes freeze in North Shore homes
Pipes in exterior wall cavities without insulation on the exterior side of the pipe, crawl spaces with inadequate insulation and venting, garage walls adjacent to conditioned space, and any pipe in a room with a heat source that's been shut off are the consistent failure locations in Lake and Cook County homes.
Safe thawing procedures when a pipe is already frozen
Shut the main water supply before thawing so any crack releases pressure rather than water. Safe thawing uses a hair dryer or heating pad on the pipe, starting from the faucet end and working toward the frozen section. Open the faucet so steam can escape. Never use a torch — copper melts, PEX burns, and structure fires start this way.
Heat tape installed incorrectly overheats and starts fires
Heat tape must be installed per manufacturer instructions without overlap — tape overlapping itself concentrates heat and is a documented fire cause. Self-regulating heat tape is safer for long runs; thermostat-controlled tape reduces energy use.
Disconnecting a garden hose bib without closing the interior shut-off
Frost-free hose bibs fail when a hose is left connected — water can't drain from the bib stem. Disconnecting hoses before the first hard freeze and confirming the interior shut-off is present and functional prevents outdoor bib freeze failures.
Questions homeowners ask
- Should I drain my pipes if I'm leaving the house for an extended period in winter?
- For absences over a week in sub-zero weather, draining the system eliminates freeze risk entirely. Set the thermostat no lower than 55 °F if you're keeping the heat on. Legendary can drain and winterize the system as a flat-rate service if you prefer not to do it yourself.
- My pipes froze last winter — how do I prevent it again this year?
- Identifying the specific location and cause is the first step — Legendary traces the freeze point and recommends the appropriate fix, whether pipe insulation, heat tape, rerouting, or insulating a crawl space.
- Does homeowners insurance cover a burst pipe from freezing?
- Most policies cover sudden and accidental water damage from a burst pipe but may exclude damage from a home left without adequate heat. Document your thermostat settings and the circumstances carefully — your insurer's requirements vary.
