How to Winterize a Rental Property: A 10-Step Checklist
The short answer
To winterize a rental, service the furnace, change filters, clean the gutters, disconnect and shut off outdoor hoses, insulate exposed pipes, seal drafts, test smoke and CO detectors, check the roof, show tenants the main water shutoff, and agree on how cold-weather problems get reported. Do it before the first hard freeze.
Start with heat and water
Winter damage in rentals almost always traces back to two systems: the heat that stops and the water that freezes. A furnace tune-up costs a fraction of an emergency no-heat call, and a burst pipe can soak a ceiling and the unit below before anyone notices. Get both handled while pros still have open schedules.
Book the furnace service now, not after the first cold night, when every HVAC tech in town is booked. Replace the filter at the same visit and leave a spare with the tenant along with a note on how often to swap it.
The 10-step winterizing checklist
Work through these in order. Most of them take minutes; the two that need a pro (furnace service and any roof repair) should be booked first.
- Service the furnace or heat pump and replace the filter.
- Clean gutters and downspouts so melting snow drains away from the foundation.
- Disconnect garden hoses and shut off and drain outdoor spigots.
- Insulate pipes in crawl spaces, garages and exterior walls.
- Seal drafts around doors and windows with weatherstripping and caulk.
- Test smoke and carbon monoxide detectors and replace batteries.
- Walk the roof line for missing shingles and flashing gaps.
- Show tenants where the main water shutoff is.
- Tell tenants when to drip faucets and to keep the heat at 55°F or higher when away.
- Agree that weak heat or a cold room gets reported the same day.
What winter problems cost if you skip it
A furnace replacement typically runs about $2,800 to $7,500, while a tune-up is a routine service call. A plumbing repair averages around $335, but a burst pipe that soaks drywall and flooring turns into a much bigger bill. The checklist is cheap insurance against both.
Frequently asked questions
When should I winterize a rental property?
In the fall, before the first hard freeze. Book furnace service early, because HVAC techs fill up quickly once temperatures drop.
What temperature should a vacant rental be kept at in winter?
Keep the heat at 55°F or higher so pipes inside walls don't freeze, and shut off and drain outdoor spigots.
Who is responsible for frozen pipes in a rental?
It depends on your lease and state law. Landlords usually maintain the plumbing and heat, while leases often require tenants to keep the heat on and report problems promptly.
