The Ultimate Pacific Northwest Winter Home Maintenance Guide

Living in Oregon and Washington means enjoying beautiful, mild summers and enduring long, wet winters. As the rainy season rolls in, prepping your home is absolutely essential. The heavy rain, wind, and occasional ice can wreak havoc on a property if it isn’t properly maintained.

Your Fall and Winter Checklist

  • Clean the Gutters: This is the most critical task for PNW homeowners. Pine needles and autumn leaves will clog your gutters fast. Blocked gutters cause water to spill over, which can lead to foundation damage, flooded basements, and rotting siding.
  • Treat for Roof Moss: Moss loves the damp, shaded environment of the Pacific Northwest. If left untreated, moss will lift your roof shingles and cause serious leaks. Apply a moss treatment early in the season.
  • Check the Drainage: Take a walk around your property during the first heavy downpour. Ensure water is pooling away from your foundation. You may need to add downspout extensions or French drains.
  • Service Your HVAC: Before the freezing temperatures hit, have a professional inspect your furnace or heat pump. Don't forget to change your air filters!
  • Disconnect Exterior Hoses: Detach all garden hoses and cover your outdoor spigots with insulated covers to prevent your pipes from freezing and bursting during a winter cold snap.
