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.

AfterChimney Cleaning in Westminster, CO
Chimney cap and crown work in Westminster runs $285-$1,850 depending on whether we’re sealing hairline cracks or pouring a new concrete crown. Most Westminster calls start with a camera inspection because the city’s 1970s-1990s prefab fireplace stock and rapid freeze-thaw cycles at 5,400 feet destroy crowns faster than masonry chimneys in older Denver neighborhoods. Call (970) 598-0453 to book a Level 2 inspection with written pricing before any work starts.
Why Westminster Homes Are Different
Westminster’s building boom from the 1970s through the 1990s filled the city with factory-built, zero-clearance prefabricated fireplace systems from brands like Heatilator and Superior. These units carried a 20-to-30-year design lifespan, meaning most are now 30 to 50 years old and aging out structurally rather than simply needing a sweep.
At roughly 5,400 feet just east of the foothills, Westminster gets hit by Chinook wind events that swing temperatures 40-60°F within hours. Those rapid freeze-thaw cycles shatter chimney crowns and open mortar joints multiple times per winter. The semi-arid, high-altitude climate also drives heavier wood-burning use on cold nights, accelerating creosote accumulation beyond what technicians see at lower-elevation Front Range cities.
In 1980s-era subdivisions around the 104th Avenue corridor, corroded manufacturer data plates inside fireboxes often leave us unable to verify clearance specs or source OEM replacement panels. We photograph and research the unit model before quoting any repair work.

BeforeAfterChimney Cap & Crown in Westminster
Chimney cap and crown work in Westminster addresses damage patterns we rarely see in older masonry neighborhoods. The city’s prefab-heavy housing stock and extreme freeze-thaw cycling at 5,400 feet mean crowns crack early, caps blow off in Chinook winds, and water intrusion destroys fireboxes before homeowners notice a problem. Chimney Cap & Crown work is often the critical repair that prevents a full system replacement.
Crown Repair
Signs you need it
Hairline cracks widening after winter, water staining on the firebox ceiling, or pieces of concrete spalling off the crown surface.
What it costs in Westminster
Crown repair in Westminster typically runs $285-$650 for crack sealing and partial resurfacing.
How we do it
We grind out cracked mortar, apply a bonding agent, and pour new crown mix sloped 1/4 inch per foot to shed water, with photos before and after under Haven Standard Clause 4.
Crown Coating
Signs you need it
Surface deterioration without deep cracking, minor spalling, or a previously repaired crown showing new wear after 3-5 winters.
What it costs in Westminster
Crown coating in Westminster typically runs $350-$725 depending on crown size and access.
How we do it
We pressure-wash the crown, apply a flexible elastomeric coating rated for freeze-thaw cycling, and document coverage with photos for your record.
What Chimney Cap & Crown Costs in Westminster
| Item | Typical range in Westminster |
|---|---|
| Crown repair | $285-$650 |
| Crown coating | $350-$725 |
| Cap installation | $185-$450 |
How long does a chimney crown repair last in Westminster?
A properly poured concrete crown with correct slope and overhang lasts 15-20 years in Westminster’s climate, though Chinook-driven freeze-thaw cycles can shorten that to 10-12 years if the original mix was too porous. We use CrownCoat or similar flexible coatings on marginal substrates to extend service life.
Can a cracked crown wait until next season?
A hairline crack can be sealed in fall before water enters freeze-thaw cycles, but a crack admitting visible water or spalling concrete needs immediate repair to avoid firebox or flue damage. We provide dated photos so you can see exactly what we’re tracking.
Chimney Liner & Rebuild in Westminster
Chimney liner and rebuild work in Westminster often starts with a cleaning call that reveals a factory-built system past its 20-to-30-year design life. Prefab units in 1970s-1990s subdivisions develop deteriorating metal fireboxes, failed refractory panels, and compromised flue systems that require full replacement rather than repair. Chimney Liner & Rebuild covers our full replacement and rebuild capabilities.
Stainless Steel Liner
Signs you need it
Corroded or perforated original liner visible on camera inspection, flue gases entering living space, or an unlined masonry chimney serving a new appliance.
What it costs in Westminster
Stainless steel liner installation in Westminster typically runs $1,850-$3,400 depending on flue length and diameter.
How we do it
We measure the flue with a video scan, drop a DuraFlex or Olympia Chimney stainless liner with proper insulation clearance, and document the full installation with photos.
Partial Rebuild
Signs you need it
Spalling brick above the roofline, a leaning chimney stack, or earthquake or wind damage confined to the upper courses.
What it costs in Westminster
Partial rebuild in Westminster typically runs $2,400-$4,800 depending on height and scaffolding needs.
How we do it
We dismantle damaged courses to sound masonry, rebuild with matching brick and proper through-flashing, and photo-document each stage under Haven Standard Clause 4.
What Chimney Liner & Rebuild Costs in Westminster
| Item | Typical range in Westminster |
|---|---|
| Stainless steel liner | $1,850-$3,400 |
| Partial rebuild | $2,400-$4,800 |
| Full chimney rebuild | $4,500-$8,500 |
Do I need a full liner or just a sweep?
A Level 2 camera inspection determines this; if the original liner shows corrosion, gaps, or perforations, sweeping alone won’t protect your home from flue gas leakage or chimney fires. We show you the camera footage and explain your options before quoting.
Can a prefab fireplace be relined, or does it need full replacement?
Factory-built units use proprietary flue systems that cannot be retrofitted with standard liners; when the firebox or flue is compromised, we replace the entire unit with a new zero-clearance system sized to your existing chase. We research your model and photograph the data plate before recommending replacement.

- Neil O."They ran a camera down the flue and showed me the cracked tiles on a screen. The previous company had swept it twice and never mentioned it."
