The forecast has the first real rain of the season landing this Thursday. After a dry Pacific Northwest summer, that sounds like relief — until you remember everything on your house has spent three months drying out, cracking, and clogging. The first heavy rain of fall doesn't create new problems. It finds every one that's been quietly building since June, all at once.
Gutters that handled spring showers fine are now packed with cedar needles and fir cones. Caulk around windows and doors has shrunk in the summer heat, opening hairline gaps. Crawlspace vapor barriers that no one has looked at since last winter may have shifted, torn, or pulled away from the foundation wall. None of that shows up until water starts moving again — and once it does, it takes the path of least resistance, which is usually straight into your home.
Why the first rain is the riskiest one
Ground that's been baked hard all summer doesn't absorb water the way it does in January — it sheds it, fast, toward whatever low spot is nearby. If that low spot is next to your foundation instead of away from it, you're set up for exactly the kind of slow seep that goes unnoticed until a musty smell shows up weeks later. Roofs behave the same way: a shingle that lifted in July's heat won't leak in dry weather, but it will the moment water starts running downhill across it.
Your 72-hour checklist
- Clear gutters and downspouts, and make sure downspouts discharge at least 4–6 feet from the foundation, not right against it.
- Check crawlspace vents and the vapor barrier for tears, gaps, or spots where it's pulled loose.
- If you have a sump pump, test it now — pour a bucket of water into the basin and confirm it kicks on and drains.
- Look at caulking around windows and doors for cracking or gaps that opened up over the summer.
- Walk the roofline (or use binoculars from the ground) for shifted, curled, or missing shingles.
- Check the grading around your foundation for low spots where water could pool instead of running off.
If water gets in anyway
Even a well-maintained home can take on water in a hard first storm, especially after a dry summer worked against every seal in the building envelope. The part that actually determines the outcome isn't whether water got in — it's how fast it gets addressed. Moisture trapped behind drywall or under flooring can support mold growth within 24 to 48 hours, and once that starts, the job gets bigger and more expensive.
If that happens, the priority is emergency mitigation: extracting standing water, setting commercial-grade air movers and dehumidifiers, and documenting moisture levels with meters and thermal imaging as you go — the kind of record your insurance adjuster will actually want to see. That mitigation work is separate from any repairs the damage might require; a mitigation team stabilizes and dries the space so a rebuild contractor can safely take over afterward.
