The short answer

Clean Gutters and Downspouts

Leaves and debris in gutters can block water flow, causing overflow that seeps into your roof, walls, or foundation. After the last leaves fall, clear out gutters and downspouts. Flush them with a hose to confirm water moves freely.

Check that downspouts extend at least a few feet from your foundation. If they dump water right next to the house, winter rain can pool and work its way into your basement or crawl space. Adjust them so water drains away from the structure.

If you live in Bellingham, keep this task on your list before the wet season begins.

  • Use a sturdy ladder and gloves when cleaning gutters.
  • Remove leaves, twigs, and any nests.
  • Check for loose or sagging gutter sections.
  • Ensure downspout connections are tight.
  • Test water flow with a hose after cleaning.

Inspect Your Roof and Attic

A damaged roof can let winter rain and snow inside, leading to water damage in your ceilings and walls. Look for missing or cracked shingles, rusted flashing, and gaps around vents or chimneys. Catching these issues in fall is easier than dealing with a leak in January.

Inside your attic, check for dark stains, moisture, or daylight coming through the roof deck. These signs suggest leaks or poor sealing. Also, make sure attic insulation is dry and evenly distributed to prevent ice dams from forming at the eaves.

If you spot problems, a roofer can handle repairs before cold weather sets in.

Drain Outdoor Water Lines

Outdoor spigots and irrigation lines can freeze and burst when temperatures drop, sending water into your walls or foundation. Disconnect garden hoses and drain the water from them. Shut off the supply valve to outdoor spigots if you have one, and open the spigot to release remaining water.

For sprinkler systems, you may need to blow out the lines with compressed air. If you are not comfortable doing this, a plumber or irrigation professional can help. This simple step prevents costly pipe bursts and the water damage that follows.

Seal Windows, Doors, and Gaps

Drafty windows and doors let cold air in and warm air out, but they also let rain and snow melt against your walls, which can cause moisture problems. Inspect weather stripping around doors and windows, and replace any that is cracked or worn. Apply caulk around window frames and door thresholds where gaps appear.

Walk around your home's exterior and look for cracks in the foundation, siding, or around utility lines. Seal these with appropriate caulk or foam. This reduces the chance of water seeping into your home during heavy winter rains.

Sealing gaps also helps with energy efficiency, so your heating system works less.

Test Sump Pump and Check Drainage

If you have a sump pump, it is your defense against basement flooding during winter storms. Pour water into the sump pit to make sure the pump turns on and drains properly. Clean the pit of debris, and check the discharge pipe is clear and directs water away from your foundation.

Also, inspect the grading around your house. The ground should slope away from the foundation so rainwater does not pool against walls. If you find low spots, add soil to improve drainage. These steps reduce the risk of water entering your home.

Policies vary, and your insurer decides what is covered.

Frequently asked questions

When should I do fall maintenance for winter?

Aim to finish before the first heavy rain or freeze, typically by late October or early November. This gives you time to address issues like roof leaks or clogged gutters before winter storms hit. If you live in Bellingham, the wet season can start early, so do not delay.

What is the most important fall maintenance task?

Cleaning gutters and downspouts is often the most critical. Blocked gutters cause water to overflow and pool near your foundation, which can lead to basement leaks and structural damage. It is a simple task that prevents big problems later.

Can I do fall maintenance myself or should I hire a pro?

Many tasks are DIY-friendly, like cleaning gutters, sealing gaps, and testing your sump pump. For roof repairs, sprinkler blowouts, or major foundation cracks, consider hiring a qualified professional. They have the tools and experience to handle tricky jobs safely.
