Winter Home Prep Checklist for Treasure Valley Homeowners

Idaho winters are hard on vacant homes. If you're leaving for the season, a month of travel, or an extended stay away, this checklist makes sure your Treasure Valley home walks into spring without a surprise. Work through it with Greg's help, and you can leave with real confidence.

Why Idaho winters are hard on homes

The Treasure Valley's freeze-thaw cycles are notoriously tough on houses. When water freezes inside pipes, it expands by roughly 9%, creating pressure that can exceed 2,000 psi. A crack as small as 1/8 inch can release 250 gallons of water per day. Ice dams form in clogged gutters and push water into walls and ceilings. Frozen hose bibs burst. Furnaces fail during cold snaps. In a home nobody is checking, these problems compound quietly for days or weeks.

The 30-day insurance vacancy clause

Before you leave, check your homeowners insurance policy. Most standard policies include a vacancy clause that limits or excludes coverage when a home is unoccupied for 30 to 60 consecutive days. Some policies also require documented inspections of the property while it's vacant. Know the terms before you go, and keep documentation that the home was being monitored.

Plumbing checklist

• Disconnect all exterior hoses and hose bibs
• Insulate exposed pipes in crawl spaces and exterior walls
• Set the water heater to vacation mode or its lowest setting
• Consider shutting off the main water supply if your plumber recommends it
• Add antifreeze to drain traps where applicable

HVAC checklist

• Set the thermostat to at least 55°F
• Replace the furnace filter before you leave
• Schedule a furnace inspection before departure

Exterior checklist

• Clean gutters and downspouts to prevent ice dams
• Blow out the sprinkler system
• Store outdoor furniture, hoses, and decor
• Check the roof for missing shingles
• Trim branches near the house

Security checklist

• Test the security system and cameras
• Set lights on timers
• Notify a trusted neighbor (and Greg)
• Forward mail or arrange collection
• Lock all windows and doors

Interior checklist

• Clean out the refrigerator and freezer
• Dispose of perishable food
• Run water through all drains and toilets to prevent dry traps
• Close the fireplace damper
• Unplug non-essential electronics

How home watch adds an extra layer of protection

A checklist gets the home ready, but it can't watch it after you leave. Weekly home watch visits catch the things checklists can't: a furnace that stops in January, a hose bib that was missed, an ice dam forming in a gutter, a pipe that was already freezing when the temperature plunged. Most insurers recommend documented inspections every 7 to 14 days for unoccupied homes.

Greg checks thermostat settings, verifies furnace operation, watches for snow load and ice dams, and reports with photos after every visit. If something's wrong, you hear about it immediately, not after the damage compounds.
