Old houses and new ones in the same small city
Black Diamond’s housing is split between old and new. Census estimates for 2020–2024 put the median build year at 2000, with half of all homes from 2000 or later, while about one in ten predates 1960 and roughly one in seventeen was built in 1939 or earlier. With about 2,400 homes in total, those figures carry some margin of error.
An older brick chimney and a newer factory-built or gas system need different things. On the older one, the questions are usually the mortar joints, the crown, the flashing and the flue lining; masonry repair and crown work are common outcomes. On the newer one, attention goes to the cap, the chase top and, for gas units, the burner and vent.
A long heating season
NOAA’s Landsburg station, about five miles north of Black Diamond, has the nearest long-term weather record. Its 1991–2020 normals include about 5,400 heating degree days a year, roughly a quarter more than Sea-Tac Airport’s 4,376, along with 59.68 inches of precipitation and 69.5 nights at or below freezing.
Heating degree days measure how much heating a climate calls for, and more of them can mean a fireplace or stove gets more use. For a wood-burning appliance, heavier use tends to mean more creosote to watch for, which makes a regular sweep more important than it is for the odd weekend fire. About two thirds of Black Diamond households heat mainly with utility gas, by the Census estimates, and few rely on wood.
Permits: City of Black Diamond
Permits for a Black Diamond address come from the city’s Community Development Department through its Permit Center, and the city’s own Building Division, with a building official and inspector on staff, carries out building inspections. Most applications are emailed to the Permit Center with the master application and the checklist for that permit type; larger building permits can go through the Citizen’s Connect portal.
The master application asks whether the site contains environmentally sensitive areas, and its list includes coal mine hazard areas alongside landslide, seismic, steep-slope and flood hazards. Have that information ready for your parcel. Whether a particular chimney job needs a permit is for the city to decide.
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.
Black Diamond chimney questions
Who reviews and inspects chimney work in Black Diamond?
The City of Black Diamond. Applications go to its Permit Center, and its own Building Division carries out building inspections, which are requested by email, through Citizen’s Connect or by phone.
The permit application asks about coal mine hazard areas. What do I do with that?
Answer it for your parcel. It is part of the city’s master application for every permit type, alongside other sensitive-area questions, and the city decides whether any of them affects your particular job.
Our new house has a gas fireplace. Does it need the same care as a wood-burning chimney?
Not the same care, because gas does not leave wood creosote in the flue. Its care is about the burner, pilot and ignition, the glass, and the vent and cap outside. Should you ever notice a gas smell, leave the house and phone 911 or the gas utility from outdoors.
Do burn bans apply in Black Diamond?
Yes. Black Diamond is in King County, so the Puget Sound Clean Air Agency’s King County status is the one to follow. A Stage 1 ban reaches wood-burning fireplaces and any uncertified stove or insert; Stage 2 reaches certified stoves and pellet stoves as well.
