Chimney services in Issaquah
Which of these applies depends mostly on what kind of fireplace and chimney you have, sealed gas unit or masonry flue. An inspection sorts that out before anything is priced.
- Gas Fireplace Service & RepairService and repair for gas fireplaces and gas inserts: pilot and ignition trouble, sooty glass, odd flames, odors, and the vent or chimney the unit uses.
- Chimney InspectionA close look at the flue, firebox, masonry and roof flashing, with photos you keep and a plain account of what’s urgent, what can wait and what can be left alone.
- Chimney Sweeping & CleaningCreosote, soot and debris cleared from the flue, smoke chamber and firebox, with before-and-after photos and a plain account of what the cleaning turned up.
- Chimney Leak & Flashing RepairTracing where water really gets in around your chimney, then repairing the flashing, crown, cap or masonry responsible, with a written scope before any work.
- Chimney Crown RepairSealing, resurfacing or recasting the slab on top of your chimney, with a real overhang, a drip edge and a flexible joint around the flue.
- Chimney Cap InstallationChimney caps measured to your flue, single or multi-flue, to help keep rain, animals, debris and embers out, with the crown checked before anything is fitted.
A young housing stock, with an older core
Census estimates (American Community Survey, 2024 five-year) put the median Issaquah home’s construction year at 2002, later than Redmond’s 1993 or Bellevue’s 1982. About 57 percent of homes were built in 2000 or later, while about 17 percent predate 1980 and about 4 percent predate 1960. The City describes Olde Town as its historic downtown, a neighborhood that predates the suburban, car-oriented form of the rest of the city.
In a newer house, the fireplace is often a sealed gas unit venting through its own pipe rather than a masonry flue. Those still need attention: the burner, the pilot or igniter, the glass and the vent all wear or collect dirt, and gas fireplace service looks at the unit and its venting together. About 46 percent of occupied homes heat mainly with gas, by the same Census estimates, and the estimate for homes heating mainly with wood rounds to zero. If you smell gas, leave first and phone 911 or the gas utility once you are outside.
For the older part of the housing stock, the familiar masonry questions apply: the crown, the mortar joints, the flashing and the flue liner.
Foothill weather
Issaquah has no NOAA climate-normals station of its own. The nearest, at Snoqualmie Falls about 10 miles east, records 63.28 inches of precipitation in a normal year, measurable precipitation on about 184 days, and about 54 nights at or below freezing (NOAA 1991–2020 normals). Seattle–Tacoma International Airport, to the west, records 39.34 inches, about 156 wet days and about 25 freezing nights.
Issaquah lies between the two, centered in what the City calls the Issaquah Alps: Grand Ridge along Cougar, Squak and Tiger mountains. The station figures show which way conditions move toward the foothills: more rain, more wet days, more freezing nights. That is hard on a chimney’s exposed parts. Water that soaks into a cracked crown or an open mortar joint and then freezes can widen the gap, and flashing has a long wet season in which to fail. Crown repair and a properly fitted cap are the usual ways to keep water out of the masonry.
Permits inside Issaquah, and just outside it
Within city limits, permits are handled by the City of Issaquah Permit Center, part of Community Planning & Development. Applications are filed through MyBuildingPermit.com.
The City’s permit page starts from a broad rule and then lists exemptions: anyone who intends to construct, alter or repair a building, or to install, alter, repair, convert or replace a gas or mechanical system, must first apply to the building official and obtain the required permit. The City notes that permits for single-family gas appliance installations can be issued over the counter online. Fireplaces and chimneys are not listed separately, so for a particular job, such as an insert, a new gas line or a crown rebuild, ask the Permit Center; the City decides.
The rural land east and south of the city is a different jurisdiction. King County’s Four Creeks/Tiger Mountain community service area covers unincorporated land there, and permits for those homes come from King County Permitting.
What you can tell us about
You do not need to know the cause. These are things homeowners describe when they get in touch — each one is something to assess on site, not a diagnosis.
Water where it should not be
Drips in the firebox, stains on a ceiling or wall beside the chimney, or a damp smell after rain.
Leak & flashing repairLoose mortar or damaged brick
Crumbling joints, brick faces flaking off, or bits of masonry on the roof or in the gutter.
Masonry repairA missing or damaged cap
No cap on the flue, a bent or rusted one, or signs that birds or animals have been getting in.
Cap installationSmoke or draft trouble
Smoke rolling into the room, a fire that is hard to keep going, or odors when the fireplace is not in use.
Chimney inspectionBuildup and a sweep that is overdue
You cannot remember the last cleaning, or you have bought a house and do not know the chimney's history.
Chimney sweepingA gas fireplace that will not light
A pilot that will not stay lit, ignition trouble, or soot on the glass. If you smell gas, leave the house and call 911 or your gas utility from outside.

How a visit works
- 1Send the short form or call. Say what you have noticed; photos you took are welcome when we talk.
- 2We arrange a time with you, look at the chimney, and photograph what we find.
- 3You hear plainly what is urgent, what can wait, and what does not need doing.
- 4Repair work comes with a written scope and price. Nothing starts until you approve it.
- 5We photograph the finished work from the same angles, and the photos are yours to keep.
What affects the price
Prices come after the chimney has been seen, in writing. These are the things that move them:
- Condition
- What the inspection finds, and whether the cause of the damage is still active.
- Access
- Roof pitch, height, how many stories up the chimney sits, and whether staging is needed.
- Chimney size
- Height above the roof, width, and how many flues the stack carries.
- Materials
- Brick and mortar matched to what is there, crown and cap materials, liner type.
- Scope
- One targeted repair, several at once, or rebuilding part of the stack.
- Permits
- Whether the work needs a permit from the city or county that has jurisdiction at the address.
Issaquah chimney questions
What happens if we burn wood during a burn ban?
The Puget Sound Clean Air Agency enforces its bans by looking for smoke from chimneys and stacks, and a violation can bring a notice and fines. During a Stage 1 ban in King County, that means no fire in a wood-burning fireplace, or in a wood stove or insert lacking EPA or Washington emission approval; Stage 2 adds every wood stove and insert, and pellet stoves. Natural gas and propane units remain allowed. Check the agency’s status page or call 800-595-4341 before lighting wood.
Our house has a gas fireplace and no masonry chimney. Is there anything to maintain?
Yes, though it differs from a wood-burning chimney. The vent pipe and its outside termination, the burner and pilot, and the glass all benefit from periodic attention; check the owner’s manual for the maker’s service recommendations. A service visit looks at the appliance and the vent as one system.
Water is showing up near our chimney. Is it the crown or the flashing?
It can be either, or neither. Water can enter through a cracked crown, porous brick or open joints, failed flashing, or an uncapped flue, and the stain inside may appear some distance from where the water gets in. Leak and flashing repair begins by tracing that path.
Do we need a permit to convert a wood fireplace to gas in Issaquah?
Plan on talking to the Permit Center. The City’s rule covers installing or replacing gas and mechanical systems, and a gas insert usually involves a gas line and a vent. The City makes the call; single-family gas appliance permits can be issued over the counter through MyBuildingPermit.com.
