A 1970s planned community that kept growing
Mill Creek began as a planned community. The city’s history panels record that the land was bought in 1972 and that its developer turned 1,073 acres of forest into about 4,600 homes around a golf course, with the first residents arriving in 1976. The city incorporated in 1983 and had annexed 17 neighboring areas by 2008, more than doubling its size.
Census estimates follow that history. The median year built is 1995, only about 15 percent of homes predate 1980, and close to 4 in 10 were built in 2000 or later. About half the housing is detached single-family homes, with attached and multi-unit housing making up most of the rest (American Community Survey, 2020–2024).
Well over half of Mill Creek homes heat mainly with gas, and the same estimates show almost none relying on wood. A fireplace here is almost always a second source of heat, which makes it easy to forget until something goes wrong.
Factory-built fireplaces, chase covers and gas units
In homes of this age the fireplace is often a factory-built unit, sometimes called zero-clearance, with a metal flue running up inside a framed chase finished in siding. Others have a sealed gas fireplace venting through a wall or the roof. Parts in these systems are made to work together, so repairs generally follow the manufacturer’s instructions for that model rather than general masonry practice.
On a framed chase, water tends to arrive at the top. A metal chase top that has rusted, or one that lets water pool, can feed moisture down into the framing around the flue, which is one reason leak and flashing repair covers chase covers as well as roof flashing. For a gas unit with ignition trouble, soot on the glass or an odor, gas fireplace service is the place to start.
Mill Creek’s permit sheet names zero-clearance fireplaces
Inside city limits, permits come from the City of Mill Creek’s Community Development and Planning department, and building permit applications go through the city’s OpenGov portal. The city’s residential “Do I Need a Permit?” sheet lists zero-clearance fireplaces, gas piping, furnace replacement and water heater replacement among common jobs that require one. Re-roofing does too, unless it is in-kind with the roof sheathing left in place.
The sheet points to the Washington State Department of Labor & Industries for electrical permits, and says it is a guide rather than a complete list. For work that touches a fireplace, flue or gas line, confirm the requirement with the city before anything starts.
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.
Gas fireplace service
With a framed chase, streaks or staining on the siding below the chimney top, or a musty smell near the fireplace after rain, are worth mentioning when you get in touch.
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.
Mill Creek chimney questions
Does replacing a fireplace in Mill Creek need a permit?
The city’s residential permit sheet lists zero-clearance fireplaces among the jobs that require a permit, and gas piping as well. The exact requirement depends on what is being replaced and how, so describe the scope to Community Development and Planning and let the city confirm it.
My fireplace has a metal flue, not brick. Does it still need sweeping?
If it burns wood, yes. Wood smoke leaves creosote wherever it cools on the flue walls, metal or masonry alike, and the EPA’s advice for wood-burning appliances is a professional inspection and cleaning every year. A gas unit has different needs, covered by gas fireplace service.
Can I use a zero-clearance wood fireplace during a burn ban?
Not during a Stage 1 air quality burn ban from the Puget Sound Clean Air Agency, which rules out wood-burning fireplaces of any construction unless the household has an approved exemption. Stage 1 still allows certified wood stoves and inserts; a Stage 2 ban stops those too.
My address says Mill Creek. Is the city always the permit office?
Not necessarily. A mailing address does not by itself place a home inside city limits. Parcels outside the city are in unincorporated Snohomish County, where county Planning and Development Services issues permits; nearby Martha Lake and Silver Firs are two such communities. The county Assessor’s property records show which jurisdiction a parcel is in.
