If you live in Bellingham or anywhere in Whatcom County, you know how unforgiving the weather can be. Strong winds, constant moisture, and heavy sideways rain put enormous pressure on your home’s exterior. Right now, many homeowners are discovering the same issue: leaky windows and siding letting water seep inside during storms.
At MOTIV Premium Painting, this isn’t new to us. We see it every season. Faded paint, cracked caulk, and aging wood siding create small openings that Pacific Northwest storms quickly exploit. Left untreated, those leaks can cause interior staining, rot, and long-term structural damage.
If your Bellingham home is showing signs of leaky windows or siding, professional exterior house painting and sealing can stop the damage - before the next downpour hits.

Why Bellingham Storms Cause Leaky Windows and Siding
Bellingham storms are especially hard on homes because wind doesn’t just bring rain straight down - it forces water sideways, straight into window frames and siding joints. North- and west-facing walls are hit the hardest.
Wood siding naturally expands and contracts in our damp climate. Without quality exterior paint and flexible sealants, gaps widen over time. Cracked caulking and peeling paint give water a direct path behind the siding and into the wall cavity.
At MOTIV we’ve repaired countless leaky windows and siding issues in Fairhaven, Ferndale, and surrounding Whatcom County neighborhoods. In nearly every case, the cause is the same: old paint systems that can no longer protect the home.
Early Signs of Leaky Windows and Siding
Catching the problem early can save thousands in repairs. Watch for these warning signs:
Inside the home
Yellow or brown stains near windows
Bubbling or peeling paint around sills
Damp smells after storms
Outside the home
Cracked or shrinking caulk lines
Soft or swollen wood siding
Moss, mildew, or flaking paint
These are all red flags that water is getting in. Experienced painters in Bellingham, WA know how to track moisture paths and fix the source - not just cover it up.
How MOTIV Premium Painting Fixes Leaky Windows and Siding

Our step-by-step approach:
Storm Damage Inspection
We inspect siding, trim, windows, and flashing to identify where water is entering.
Deep Cleaning & Prep
Power washing removes dirt and moss, exposing hidden cracks. Loose paint is scraped, and damaged areas are repaired.
Targeted Priming
Moisture-blocking primers are applied to vulnerable areas around leaky windows and siding.
High-Performance Exterior Painting
Two coats of durable, mildew-resistant paint - often flexible acrylics or elastomeric coatings - built to handle wind and rain.
Full Sealing
All joints, seams, and window frames are sealed using professional-grade exterior caulks that remain flexible year-round.
The result is a weather-tight exterior that looks great and performs even better.
