Fall is settling in across Oregon. The air’s cooler, the skies are gray, and the rain has started to make itself at home. Around here, that means one thing: it’s time to make sure your house is ready for whatever the next few months bring.
Here’s what every Oregon and SW Washington homeowner should focus on now before the winter weather strikes.
Home Winterization Tips
Clean Gutters and Downspouts
For those of us on the west side of the Cascades, rain is just part of winter life. But if your drains are clogged, that water can end up in places it doesn’t belong, like your basement or crawlspace, leading to mold and structural damage. In freezing conditions, clogged gutters can lead to ice dams, which trap water on your roof and force it underneath your shingles, causing leaks and rot.
Check for leaves, needles, and debris, and make sure your downspouts carry water well away from your foundation — at least six feet if possible.
Pro Tip: Install quality gutter guards once and save yourself a weekend every fall. Mesh-style guards keep out up to 95% of debris and still let the rain flow freely.
Shut Down Irrigation Systems
When temperatures drop below freezing, any remaining water in your irrigation system can freeze, expand, and crack the pipes or sprinkler heads. Draining your system can be done by turning off the water supply, manually opening drain valves, and, if possible, using an air compressor to blow out any remaining water in the lines. While you’re at it, don’t forget to disconnect and drain garden hoses and leave outdoor faucets open to prevent freezing.
Pro Tip: Consider installing a system with an automatic blow-out valve. It uses temperature sensors to drain water before the freeze hits.
Service Your Furnace & HVAC System
Your heating system works hardest when temperatures drop, so fall is the time to make sure it’s ready. Replace the air filter, clean around the furnace or heat pump, and test the system before the first real cold spell. If you hear odd noises or notice uneven heating, schedule a service visit before technicians get busy.
Furnaces that are not properly maintained can also be a fire hazard. Make sure to keep the area around your furnace clear of flammable materials, and don’t ignore any strange smells or noise.
While you’re at it, check to see if your vents are covered by furniture or rugs; clearing them will allow for proper airflow.
Pro Tip: If your furnace is more than 10 years old, ask your technician whether a variable-speed or high-efficiency unit could reduce long-term costs. These systems adjust airflow automatically and handle Oregon’s temperature swings with less energy waste.
Test Smoke and Carbon Monoxide Detectors
Cold weather means closed windows, running furnaces, and more time indoors — all of which make good ventilation and working detectors even more important. Go room to room and press the test button on every smoke and carbon monoxide detector. Replace batteries and check the manufacturing date printed on the back; most smoke alarms last about 10 years, and CO detectors about 5 to 7.
If you can’t remember when you installed them, it’s probably time to replace them.
Pro Tip: Consider upgrading to smart detectors. They test themselves automatically, send alerts to your phone if something’s wrong, and even remind you when batteries run low.
Protect Exterior Faucets and Hose Bibs
A frozen outdoor faucet is one of the easiest ways for water to end up inside your walls. As temperatures drop, disconnect all hoses and drain any remaining water. If your home has a shutoff valve inside, close it and open the exterior faucet to release pressure.
Once drained, cover each faucet with an insulated cap to protect it through winter. These simple foam covers cost just a few dollars and can prevent thousands in damage. In areas with harsher or extended cold spells, and especially east of the Cascades, it’s worth investing in heavy-duty insulated covers for extra protection.
Don’t forget to disconnect any attached hoses and drain them before storing them for the winter. Leaving hoses attached can trap water inside the faucet and increase the risk of freezing.
Pro Tip: If your faucets are older or exposed, consider upgrading to frost-free hose bibs. They sit deeper in the wall so the shutoff stays in the warm interior.
Insulate Pipes
Even in Western Oregon, cold snaps can catch homeowners off guard. Any pipe running through an unheated space — like a crawlspace, basement, or garage — is at risk of freezing. Wrap those pipes with foam insulation sleeves or fiberglass wrap to keep the cold out. Pay special attention to bends, joints, and areas near vents or open foundations.
For homes in Central or Eastern Oregon, where winter temperatures drop lower for longer, take it a step further. Add self-regulating heat tape along critical lines and plug it into a GFCI outlet. These systems sense temperature and warm the pipe only when needed, saving energy while preventing bursts.
Pro Tip: Before insulating, check for slow leaks or corrosion.
Get a Chimney Inspection
If you use a fireplace during the winter, a chimney inspection is a must. Over time, creosote (a highly flammable substance) can build up in your chimney, increasing the risk of a chimney fire. Additionally, blockages from debris or animal nests can prevent proper ventilation, which could cause dangerous carbon monoxide buildup in your home.
Schedule an annual inspection and cleaning by a certified chimney sweep to ensure your chimney is safe and ready for winter use. This is especially important if you haven’t had it cleaned in a while or plan on using your fireplace frequently.
Pro Tip: Consider installing a chimney cap to prevent leaves, debris, and critters from getting into your chimney. It’s a small investment that can save you from dealing with blockages or unwanted visitors during the colder months.
Test Your Sump Pump
When Oregon’s winter rains start to pile up, your sump pump is the last line of defense between your home and a flooded basement. Before the season shifts, pour a few gallons of water into the sump pit and make sure the pump activates and drains properly. If it hesitates, runs loudly, or doesn’t switch on at all, have it serviced or replaced before the next big storm.
While you’re at it, inspect the discharge line outside. It should drain away from your foundation and be free of blockages or ice buildup.
Pro Tip: A battery backup system can save you when power goes out during a storm. Some newer models even send alerts to your phone if the water level rises too high or the pump fails.
Cover Crawlspace Vents
Crawlspace vents are meant to let moisture escape during the summer, but in winter they can do more harm than good. Cold air blowing through those openings can freeze pipes, chill floors, and drive up heating costs.
Once the weather turns consistently cold, cover the vents with rigid foam or insulated panels. Just remember to remove them in spring to allow air circulation again.
Pro Tip: If you’re sealing vents for the whole season, consider placing a small dehumidifier or humidity sensor in the crawlspace. That extra visibility helps prevent mold growth while keeping your insulation dry.
Install a Smart Water Shutoff System
A burst pipe can release hundreds of gallons of water in minutes. For Oregon homeowners, that often means coming home after a weekend away to find a flooded crawlspace or soaked floors. A smart water shutoff system, like the Moen Flo, helps stop that before it happens.
Installed on your home’s main water line, the system continuously monitors water pressure, temperature, and flow. If it detects an abnormal pattern — like a sudden burst or slow, unseen leak — it automatically shuts off the water and sends an alert straight to your phone.
Pro-Tip: Have a licensed plumber handle installation and calibration. For professional installation, our sister company On The Way Plumbing can set up and configure Moen Flo systems.
Clear Yard Debris and Protect Drainage
Leaves, branches, and other debris don’t just clutter up your yard — they can block drainage paths and trap moisture around your foundation. After the last big leaf fall, rake or blow debris away from siding, vents, and window wells. If you have a flat or low-slope roof, make sure drains and scuppers are clear, too.
Pay special attention to areas where water naturally pools or where soil touches the base of your home. Moisture against siding can lead to rot or allow small cracks in the foundation to widen over time.
Pro Tip: Keep a few feet of open space between landscape mulch or bark dust and your foundation. It helps soil dry out faster after heavy rain and makes it easier to spot early signs of drainage issues.
Bonus Tips for Pacific Northwest Homes
Even when you’ve checked every box on your winter prep list, a few extra steps can make a big difference once storms hit.
- Watch your roofline after heavy rain. Overflowing gutters or water dripping behind fascia boards can indicate hidden clogs or flashing gaps that need attention.
- Plan ahead for ice and snow removal. Keep pet-safe de-icer and traction sand stocked early — stores often sell out right before the first freeze.
- Trim trees away from the roofline. Winter wind and ice can bring down weak branches fast. Keeping limbs back a few feet reduces risk to shingles and gutters.
- Inspect basement and crawlspace humidity. A simple hygrometer can tell you if moisture levels are creeping up. Anything above 60% means it’s time for better ventilation or a dehumidifier.
Pro Tip: Perform a quick visual check of your home after the first major storm. Spotting small issues early, pooling water for example, can prevent the kind of repairs that keep our restoration crews busiest later in the season.
