What we see with waterproofing and flashing in Arlington

Arlington homes leak where wind and rain across the open Stillaguamish valley hit exposed walls, decks and outbuildings hard. With 1990s–2010s subdivisions and rural homes on larger lots, the most common failures are missing kick-out flashing, caulk-only wall penetrations and windows with no sill pan.

Arlington is a short drive north of our Marysville base. We regularly work in Smokey Point, downtown Arlington, Gleneagle and Arlington Heights.

Arlington sits in the Stillaguamish River valley, where open farmland lets wind and rain hit homes and outbuildings with little shelter. 1990s–2010s subdivisions around Smokey Point and Gleneagle, older homes near downtown, and rural homes with shops and barns.

Waterproofing & Flashing in Arlington: what you should know

Flashing is what turns water away at every joint and opening in an exterior wall. In Arlington, 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 Arlington

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 Arlington

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.

Every waterproofing and flashing job starts with a free on-site inspection, moisture readings and photos, and you get a written scope and price before work begins. We are licensed, bonded and insured in Washington, and our repairs carry a 24-month workmanship warranty.
