Quick Answer
Okay, here’s the quick version. Most fall and winter water damage comes from two things: clogged gutters and burst pipes. An ounce of prevention is worth a truckload of cure, believe me. You'll want to clean your gutters before the snow flies and insulate any pipes in cold spots like your crawlspace. If you do it yourself, you're looking at maybe $50-100 in materials. If you have to call me or another pro out to fix a mess, you’re starting at a few hundred bucks and it can go up into the thousands. Fast.
Common Symptoms
Possible Causes
Step-by-Step Diagnosis
Step 1
Exterior Walk-Around: Inspect gutters for debris, downspout function, and look for visible damage to the roof and siding.
Step 2
Check Ground Slope: Verify that the ground around your foundation slopes away from the house to promote proper drainage.
Step 3
Foundation Inspection: Carefully examine the visible foundation for any cracks, especially horizontal or large, jagged cracks.
Step 4
Interior Inspection: Go to the basement, crawlspace, and attic with a flashlight to look for water stains, mold, dampness, and efflorescence.
Step 5
Use a Moisture Meter: In areas that look suspicious, use a moisture meter to confirm elevated moisture levels within drywall or wood.
Step 6
Monitor During Storms: Observe problematic areas during heavy rain or snowmelt to pinpoint the exact source of water entry.
Step 7
Pipe and Appliance Check: Inspect exposed water pipes for insulation and look for any signs of leaks around water heaters, washing machines, and spigots.
