Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Chimney Cleaning in Westminster, CO
Chimney cap and crown work in Westminster runs $285-$1,850 depending on whether we’re sealing hairline cracks or replacing a failed crown and cap assembly. Most Westminster calls start the same way: a brown stain on the chase ceiling or rust streaks down the siding after a Chinook wind event ripped through. We’re Level Two Chimney Co., and we quote every job in writing before work starts at (720) 439-4666.
Why Westminster Homes Are Different
Westminster’s building boom from the mid-1970s to mid-1990s filled the city with factory-built, zero-clearance fireplaces in ranch and split-level tract homes. These metal flue systems hit their 20-30 year design lifespan years ago. At 5,300 feet, reduced oxygen means cooler, incomplete combustion and faster creosote buildup than lower-elevation cities see.
Chinook winds hammer Westminster several times each winter. Sudden pressure swings crack crowns, heave mortar, and cause backdrafts that homeowners mistake for dirty flues. Many chase covers from the 1980s and 1990s are rusted through. The original caps were undersized for Front Range wind loads. We inspect with a camera down the flue on every visit - Clause 4 of the Haven Standard - because flashlight looks miss the crown cracks and liner gaps these homes hide.

Before
AfterChimney Cap & Crown in Westminster

Westminster’s 1970s-1990s prefab fireplaces shipped with thin-gauge metal chase covers and minimal caps that corrode and blow off in Chinook winds. Crown cracking runs rampant here because factory-built crowns weren’t designed for Front Range thermal shock. We replace caps with wind-rated models and repair or pour crowns that actually shed water. Chimney Cap & Crown work is what keeps moisture out of your chase and flue.
Cap Replacement
Signs you need it
Rust streaks down the chase, a missing or rattling cap after wind, or birds nesting in the flue.
What it costs in Westminster
Cap replacement runs $285-$650 installed, with stainless multi-flue caps at the higher end for wind resistance.
How we do it
We measure the flue or chase opening, fabricate or order the correct cap from Gelco or Olympia Chimney, and secure it with proper fasteners and sealant.
Crown Repair
Signs you need it
Visible cracks in the crown surface, water stains on the chase interior, or pieces of concrete falling into the firebox.
What it costs in Westminster
Crown repair with professional-grade coating ranges $450-$850; full crown replacement runs $1,200-$1,850.
How we do it
We grind out cracks, apply bonding agent, and trowel on a flexible crown coat rated for freeze-thaw cycling, or form and pour a new concrete crown with proper overhang and drip edge.
What Chimney Cap & Crown Costs in Westminster
| Item | Typical range in Westminster |
|---|---|
| Cap replacement | $285 - $650 |
| Crown repair / coating | $450 - $850 |
| Full crown replacement | $1,200 - $1,850 |
How long does a chimney cap last in Westminster?
A quality stainless cap lasts 15-20 years, but the original galvanized caps on 1980s Westminster homes often fail in 7-10 years due to altitude UV and Chinook corrosion. We stock wind-rated stainless models from Gelco and Olympia Chimney.
Can a cracked crown wait until next season?
Hairline cracks can be coated if the crown is structurally sound, but water infiltration through open cracks freezes and expands, turning a $600 repair into a $1,800 replacement. We photograph the crown and show you exactly what we found.
Chimney Liner & Rebuild in Westminster

Westminster’s aging prefab fireplaces use metal flue pipe, not clay liners, but many homeowners with older masonry chimneys or converted boilers face failed clay or unlined brick flues. At 5,300 feet, incomplete combustion produces acidic condensate that corroges metal and erodes mortar faster. Liner failure means carbon monoxide risk and code violation. Chimney Liner & Rebuild work starts with a camera scan to document what you actually have.
Stainless Steel Liner
Signs you need it
Flue tiles falling into the firebox, visible gaps or cracks in a clay liner, or a boiler/furnace venting into an unlined masonry chimney.
What it costs in Westminster
Stainless steel liner installation runs $2,800-$4,500 depending on flue diameter, height, and appliance connections.
How we do it
We drop a video camera to assess the flue, measure for a custom-fabricated DuraFlex or HeatShield liner, and install with proper insulation pack and top plate.
Partial Rebuild
Signs you need it
Spalling brick above the roofline, a leaning chimney stack, or mortar joints eroded to finger-width gaps.
What it costs in Westminster
Partial rebuilds from the roof up typically run $3,500-$6,500 depending on accessibility and brick matching.
How we do it
We scaffold the work area, dismantle damaged courses to sound masonry, and rebuild with matching brick and proper crown and flashing integration.
What Chimney Liner & Rebuild Costs in Westminster
| Item | Typical range in Westminster |
|---|---|
| Stainless steel liner | $2,800 - $4,500 |
| Flexible liner (gas appliance) | $1,800 - $3,200 |
| Partial rebuild | $3,500 - $6,500 |
Does my prefab fireplace need a liner replacement?
Factory-built fireplaces use Class A metal flue pipe, not a separate liner. If that pipe is rusted or separated, we replace the chase cover and cap first, then assess whether the manufacturer still supports the firebox model.
How do I know if my clay liner is cracked?
You don’t without a camera. We run a video scan on every inspection - Clause 4 of the Haven Standard - and show you the footage before quoting any liner work.
Brands We Service in Westminster
We stock caps, liners, and repair materials from HeatShield, Gelco, Olympia Chimney, and Famco through Haven’s buying network. Most cap and crown parts arrive within 24-48 hours; liner jobs typically schedule within a week of written approval.

FAQs About Chimney Cleaning in Westminster

Most chimney cleaning and cap replacement does not require a permit, but crown replacement and any structural rebuild need a Westminster building permit. We pull permits as part of the job when required and include the cost in your written quote.
NFPA 211 recommends annual inspection; sweeping frequency depends on use. At Westminster’s altitude, the same fire produces more creosote than at sea level, so heavy-use wood fireplaces often need sweeping every cord of wood burned.
Yes. We document our license and insurance for any HOA or property manager, and we schedule access around HOA maintenance windows. Written quotes include scope details that satisfy most architectural review requirements.
