As temperatures drop and Portland settles into its rainy cold season, it’s easy to shift straight into cozy mode—blankets, warm drinks, and holiday plans. But before you hunker down, give your home a little attention too while we still have sunny days like today to enjoy.
Winter prep doesn’t have to mean a major project or a big expense. It’s about catching small issues, keeping up with maintenance, and making a plan before the weather turns.
Whether you’re a first-time homeowner or a seasoned pro, this checklist will help you get ready for the wet, chilly months ahead.
Get ready! Winter is just around the corner.
Why Winter Prep Matters in Portland
In the Pacific Northwest, getting ready for winter means thinking about more than temperature. It also means managing water—from the rain hitting your roof to the moisture building up inside your home.
Clogged gutters, roof leaks, and poorly vented steam can all contribute to mold problems. Taking care of those trouble spots now helps keep your home drier and more comfortable throughout the season.
The goal isn’t to make your home entirely winter-proof. It’s to spot what needs attention before a small problem becomes an unwelcome surprise.
Inside Prep: Keep the Warmth In—and Moisture Under Control
Start with your heating system
If your heating system hasn’t been checked since last winter, put a service appointment on your list. Check the filter, too, and follow your system’s maintenance and replacement instructions.
While you’re working through the indoor checklist, test your smoke and carbon monoxide alarms. These aren’t the most exciting home projects, but they deserve a spot near the top.
Find the drafts
Walk around your windows and exterior doors on a chilly morning. Feel a breeze? Check whether worn weatherstripping, gaps, or a tired door sweep need attention. We like to use a stick of incense around windows and doors to easily see if air is being pulled out or drafting in.
Then bring on the cozy layers: thicker curtains, rugs over chilly floors, and a few well-placed blankets. Comfort doesn’t always require a renovation!
Give moisture its own checklist
A cozy home shouldn’t feel damp. This year, add a quick moisture check to your winter routine:
Use exhaust fans to move cooking and shower steam outdoors.
Look for condensation on windows and signs of leaks beneath sinks.
Pay attention to musty smells or damp areas in basements and other less-used spaces.
Ever been in your crawlspace? Many homeowners don’t, but this is the best way to catch any standing water or moisture problems right away!
Consider a humidity monitor to take the guesswork out of indoor moisture.
Oregon Health Authority recommends keeping indoor humidity between 30% and 60%. If moisture keeps returning, address the source rather than simply wiping it away.
Outside Prep: Keep Water Where It Belongs
Check gutters, downspouts, and the roof
Leaves have a way of settling in just as the rain picks up. Add gutter cleaning and a visual roof check to your fall maintenance list, and look for obvious damage or overflowing gutters.
Roof and gutter leaks are among the moisture sources Oregon Health Authority recommends inspecting and repairing to help prevent mold.
Keep your own inspection to places you can safely access like any attic areas, and bring in a professional for dangerous roof work or difficult-to-reach areas.
Remember outdoor water sources
Disconnect garden hoses and put exterior faucet protection on your before-the-freeze checklist. If you’ve been meaning to figure out where your main water shutoff is, make that part of this year’s prep, too.
Watch drainage and walking paths
During the next rain, take a look at where water collects around your property. Note overflowing gutters, puddles near the house, or trouble spots along your usual walking route.
Clear leaves from steps and walkways, check exterior lighting, and put away patio items you won’t use until spring. Future you will appreciate having fewer things to deal with when the weather gets messy.
Add a Storm-Readiness Check
Alongside the usual maintenance, give your household’s winter plan a quick refresh:
Where are the flashlights, and do they work?
Are portable chargers ready?
Is your utility’s outage-reporting information easy to find?
Who would need help if the house lost heat?
Where could you go if staying home became unsafe?
Portland’s community resilience guidance recommends going to a warming shelter if your home loses power during extreme cold and calling 211 for help.
What’s New for 2026: Recheck Energy-Upgrade Incentives
Thinking about a heat pump, insulation, or new windows? Don’t build your budget around last year’s incentive information.
The federal Energy Efficient Home Improvement Credit ended for property placed in service after December 31, 2025. That means qualifying improvements installed in 2026 no longer receive that particular federal credit.
Local incentives are a separate story. Energy Trust of Oregon continues to advertise incentives for eligible efficiency upgrades, but some offers and equipment requirements changed for 2026. Before signing a contract, confirm current eligibility, qualifying equipment, application timing, and available funding directly with the program and your contractor.
The takeaway: an upgrade may still come with financial help—just make sure you’re using today’s information, not an old estimate.
A Little Prep, Then Back to Cozy
You don’t have to tackle everything in one weekend. Start with the most important maintenance, handle the easy fixes, and schedule help for anything beyond your comfort zone.
Then pour something warm, grab a blanket, and enjoy the season knowing you’ve given your home a little extra care.
