What we see with waterproofing and flashing in Marysville
Marysville homes leak where wind-driven rain off the flats around Ebey Slough hits south and west walls hard, and flashing details missed during fast construction show up a decade later. With a mix of older homes near downtown and a large share of 1990s–2010s subdivisions built quickly, the most common failures are missing kick-out flashing, caulk-only wall penetrations and windows with no sill pan.
Marysville is one of our two home bases, so scheduling here is usually quick. We regularly work in Sunnyside, Getchell Hill, Lakewood, Smokey Point, Kellogg Marsh and Shoultes.
Marysville spreads from the flats along Ebey Slough up to Getchell Hill and the Sunnyside plateau, and the open ground lets wind-driven rain hit walls hard. Older homes near downtown, a large share of 1990s–2010s subdivisions, and newer builds around Lakewood and Smokey Point.

Waterproofing & Flashing in Marysville: what you should know
Flashing is what turns water away at every joint and opening in an exterior wall. In Marysville, almost every rot repair we do traces back to flashing that was missing, installed backwards, or replaced with caulk. Good waterproofing is mostly about laps: each layer overlaps the one below it so water always runs out.
What causes it in Marysville
Kick-out flashing missing
Roof water pours into the wall where the roof edge meets siding.
No sill pans under windows and doors
Water that gets into the opening has nowhere to drain except into the framing.
Caulk-only penetrations
Dryer vents, pipes and lights without a flashed block leak once the caulk cracks.
Failed deck and balcony coatings
Walking surfaces over living space crack and let water into the framing below.
What our waterproofing and flashing includes
- Water testing and inspection to find the actual entry point
- Opening only the area needed around the problem
- Kick-out flashing, head flashing, sill pans and Z-flashing
- Flashed mounting blocks for vents, lights and pipes
- Flashing tape lapped shingle-style into the weather barrier
- Deck and balcony membranes or coatings where needed
- Siding and trim reinstalled and sealed
How to prevent it
- Check caulk joints every fall, but do not rely on caulk alone
- Look for stains below vents, lights and roof edges
- Keep gutters running so roof edges are not overloaded
- Ask for kick-out flashing whenever a roof is replaced
- Recoat balcony surfaces on the manufacturer's schedule
What affects the cost in Marysville
Most flashing repairs are small in area, so the cost is mostly labor to remove and reinstall siding around the detail. If rot is found behind it, framing and sheathing repair is added, which is why fixing flashing early is the cheapest exterior repair you can make.
How long it takes
Single flashing details usually take a few hours to a day. Balcony and deck waterproofing typically takes two to four days including cure time.
