DuPont, Pierce County
Chimney flashing repair in DuPont costs $330 to $1,500. Resealing a joint that has opened along an otherwise sound flashing is at the low end; tearing out and replacing the full set of step and counter flashing, with the shingles around it, is at the high end. We trace where the water gets in before quoting, because a stain on a ceiling near the fireplace is not always the flashing's fault.

Flashing is the metal that bridges the gap between a chimney and the roof around it, and in DuPont it comes in two varieties. On masonry stacks in the older village it is tucked into the mortar joints and bent over the shingles. On the framed chases of the newer neighborhoods it is the same step flashing used against any wall, lapped under the siding. Both rely on sealant at a few critical points, and sealant ages faster than metal, especially on south-facing roofs that bake in summer and stay damp all winter.
Only about 5.6 percent of DuPont's housing units date from before 1960, according to the Census estimates, and the town's median home was built in 2002. The rest of the picture follows from its history: the DuPont Company's workers' village, sold to its tenants in 1951, and the Northwest Landing development approved in 1989.
That split decides how the flashing is built. A chase clad in siding is flashed like a wall, with the step pieces behind the siding's weather barrier; a brick stack needs counter flashing set into a sawn mortar joint. We repair each according to how it was originally put together.
Every chimney flashing repair we do in DuPont includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowLeaks at the chimney usually show up in one of three places: a brown water stain on the ceiling next to the fireplace, damp drywall in an upstairs closet that backs onto the chase, or drips on the hearth itself. In homes built in the 2000s, we often find the original sealant has cracked at the top of the counter flashing, or that a roofer replacing shingles reused old step flashing that had already been bent twice.
We look at the stain inside, then the roof above it, and check the crown, cap and siding so the flashing is not blamed for someone else's leak.
You get a written quote that says whether a reseal will do or whether the flashing needs to come out, with each line priced.
Shingles are lifted, new step pieces are woven in course by course, and counter flashing is cut into the mortar or lapped under the siding.
Exposed edges are sealed with a flexible compound suited to metal and masonry, and you receive photos of each stage.

WeatherSpark shows DuPont's wetter season lasting about 6.8 months, with November averaging around 8.6 inches of rain and July only about 0.7. December is gray about three-quarters of the time, so a roof that gets wet in the fall seldom dries out before spring.
On the uphill side of a chimney, that water has nowhere to go but against the flashing. The 2021 Washington residential code handles the worst case with a cricket: one is mandatory behind a stack more than 30 inches across, measured parallel to the ridge, unless the chimney meets the ridge itself. We check for one on every wide stack.
DuPont is a former company town built around an explosives plant, joined since 1989 by the planned Northwest Landing, with mostly recent homes — a median build year of 2002 — around a historic company village. We work every part of it — the Historic Village, Northwest Landing included.

The metal usually holds up; what gives out first is the sealant at the joints. It dries and cracks after enough summers of heat and winters of rain, and water follows the crack.
It is a small peaked ridge built behind the chimney to split the runoff. Washington's code requires one when a chimney wider than 30 inches sits below the ridge rather than on it.
