DuPont, Pierce County
Installing a chimney cap in DuPont costs $265 to $750. A standard stainless cap on a single flue sits at the lower end; a multi-flue cover or a custom-made top for an odd-sized chase lands near the upper figure. On most newer homes in town the cap is part of a factory-built chimney, so the replacement has to be the one listed for that system, not just any hood that happens to fit.

The houses in DuPont's planned neighborhoods mostly went up after 1989, and a lot of them share the same arrangement: a wood-framed chase sided to match the house, a sheet-metal cover across the top, and a manufacturer's termination cap on the pipe. Those parts weather at different speeds. A painted chase cover can rust through while the cap above it still looks fine, and a cap fastened with a few small screws can loosen after several windy winters. In the older village, masonry flues take a cap anchored to the tile liner or the crown instead.
Every chimney cap installation we do in DuPont includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowWhat usually prompts a call is noise or water. Homeowners hear birds or rustling in the chimney in spring, or they see a drip line down the inside of the firebox after a storm. Sometimes a cap is simply missing, lifted off during a gusty night and found in the yard. Each of those points to the same fix, but on a prefabricated chimney we first read the model plate so the new cap matches the original listing.
The 2021 Washington State Residential Code spells out what a spark arrestor must do: stop any sphere wider than half an inch, let a three-eighths-inch sphere pass, and have a screen that detaches for cleaning. It also sets a minimum height for masonry stacks, three feet clear of the roof penetration and two feet over any part of the building closer than ten feet, and that height decides how exposed the cap will be.
A chimney cap belongs on the list next to a yearly inspection and sweep, according to the State Fire Marshal's advice on heating safely. When we fit one, we check that the mesh meets the code size rather than a finer screen that clogs quickly.
On masonry we measure each flue opening; on a factory-built chimney we record the brand and model so the correct listed cap is ordered.
Nests, leaves and loose debris are removed before anything is fitted, so the new cap does not trap them.
The cap is secured to the liner, the crown or the pipe with fasteners suited to that material.
You receive pictures of the new cap from the roof along with a note on the condition of the chase cover or crown.

According to WeatherSpark, DuPont's windier season lasts about 6.2 months, from mid-October to late April, with November averaging close to 4.9 mph hourly winds. The wet season overlaps almost exactly, so the months when caps get pushed around are also the months when an open flue takes in the most rain.
Oregon State University Extension adds that moss on Northwest roofs traps debris and moisture. Under shaded trees, that material can collect on a chase cover, so we clear it while we are up there.
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.

Between $265 and $750 installed. Single-flue stainless caps sit near $265; covers spanning several flues or built to order for an unusual chase run toward $750.
No. A factory-built chimney is tested with a specific termination, and substituting a different one can affect how it vents. We match the replacement to the maker's listing.
A cap with a mesh screen acts as a spark arrestor. Washington's residential code sizes that mesh so it blocks larger embers, and it has to come off for cleaning.
