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 typically runs $650-$2,400 depending on whether we’re sealing a hairline crack or replacing a deteriorated crown and cap assembly. Most Westminster calls start with the same story: the homeowner noticed water spots on the ceiling near the fireplace after a Chinook wind event, or they found grit and mortar crumbs in the firebox. We’re Level Two Chimney Co., and we send a camera down every flue before we quote anything in writing. Call (720) 674-7312 to book a Level 2 inspection with documented photo record.
Why Westminster Homes Are Different
Westminster’s housing boom ran from the late 1970s through the mid-1990s, and builders here installed prefabricated zero-clearance metal fireplaces as standard. Those units are now 25-45 years old, well past their 20-25 year design life. At 5,390 feet elevation, Westminster sits higher than Denver proper, squarely in the Chinook wind belt. Those warm, dry downslope winds drive rapid freeze-thaw cycles all winter, cracking mortar crowns and spalling brick far faster than in lower suburbs.
The semi-arid climate also shapes how Westminster burns. Cold snaps send residents to their fireplaces hard and fast, producing glazed third-degree creosote that needs chemical treatment before mechanical sweeping. In subdivisions north of 104th Ave built in the late 1980s, we routinely find warped firebox back panels on prefab units whose exterior chase looks fine. Adams County requires a permit for firebox replacement, a step many homeowners don’t realize is triggered by what looks like a simple repair.
Our Main Westminster Services
Westminster homeowners call us most often for these three services, each with its own local page and pricing.
Chimney Cleaning & Sweep in Westminster
We sweep masonry and factory-built systems throughout Westminster, from the ranch tracts near US-36 to the two-story clusters off I-25. Every sweep includes a Level 2 camera inspection, creosote classification, and a written condition report with photos. Chimney Cleaning & Sweep in Westminster covers seasonal timing, what Class III creosote means for your system, and how we handle prefab metal units common here.

Chimney Repair in Westminster
Crown cracks, spalling brick, and deteriorated mortar joints accelerate in Westminster’s freeze-thaw cycle. We document everything with photos before quoting, and we pull permits when Adams County requires them. Chimney Repair in Westminster details tuckpointing, crown rebuilding, and chase cover replacement for the area’s aging prefab fireplaces.

Fireplace Services in Westminster
Factory-built fireplace repair, gas insert troubleshooting, and refractory panel replacement make up most of our Westminster fireplace work.

AfterChimney Cap & Crown in Westminster

Westminster’s Chinook-driven temperature swings, sometimes 40°F in hours, destroy chimney crowns faster than almost any Denver suburb. The late-1970s through mid-1990s build-out means most masonry chimneys here are 30-50 years old, with original crowns poured from weak mortar mixes that weren’t designed for Front Range thermal shock. We inspect every crown with a camera and moisture meter before recommending repair or replacement, and we quote in writing before any work starts. Chimney Cap & Crown covers our full material and method standards.
Crown Repair
Signs you need it
Water in the firebox after rain, visible cracks wider than 1/8 inch on the crown surface, or mortar crumbs collecting on the smoke shelf.
What it costs in Westminster
Crown repair in Westminster typically runs $650-$1,200 for crack sealing and resurfacing, while full crown replacement ranges $1,800-$2,400.
How we do it
We grind out cracked mortar, apply a bonding agent, pour new high-compression crown mix sloped 1/4 inch per foot for drainage, and finish with a waterproofing sealant rated for freeze-thaw cycling.
Cap Installation
Signs you need it
Rust streaks down the chimney face, debris or animal nesting material in the flue, or water dripping from the damper when it hasn’t rained.
What it costs in Westminster
Single-flue stainless cap installation in Westminster ranges $280-$550; multi-flue caps or custom chase covers run $650-$1,400.
How we do it
We measure the flue or chase opening, fabricate or source a 304 stainless cap with 3/4 inch mesh screening, and secure it with masonry screws or a compression-fit mounting system that won’t damage the flue tile.
What Chimney Cap & Crown Costs in Westminster
| Item | Typical range in Westminster |
|---|---|
| Crown crack repair / resurfacing | $650 - $1,200 |
| Full crown replacement | $1,800 - $2,400 |
| Single-flue cap installation | $280 - $550 |
| Multi-flue cap / chase cover | $650 - $1,400 |
Can a cracked crown wait until next year?
Not safely in Westminster. Chinook freeze-thaw cycles widen cracks exponentially; we’ve documented 1/8-inch cracks growing to full crown failure in a single winter. Water intrusion then damages the flue liner and smoke chamber, turning a $800 repair into a $3,000+ rebuild. Call (720) 674-7312 for a camera inspection and written quote.
Do I need a permit for crown work in Westminster?
Adams County requires permits for crown replacement exceeding 25% of the chimney structure; cosmetic sealing and cap installation typically do not. We pull permits when required and include the cost in your written quote. The permit ensures the work meets local wind-load and freeze-thaw specifications.
Chimney Liner & Rebuild in Westminster

Westminster’s prefab metal fireplaces are aging out en masse, but the masonry stock faces its own crisis: original clay flue tiles, installed 1975-1995, have endured 30-50 years of thermal cycling at 5,390 feet with aggressive burning patterns. Chinook winds create rapid temperature drops that shock liner tiles; we’ve pulled fractured tiles in Westminster chimneys whose owners had no idea until the camera went down. When the liner fails, combustion gases leak into wall cavities. We quote liner replacement and rebuild options in writing after Level 2 inspection, with photos you can see for yourself. Chimney Liner & Rebuild details our full scope and warranty terms.
Stainless Steel Liner
Signs you need it
Flaking tile pieces in the firebox, smoke smell in upstairs rooms when the fireplace is cold, or a home inspector flagged “suspected liner deterioration” at sale.
What it costs in Westminster
Stainless steel liner installation in Westminster ranges $2,800-$4,500 for a single-flue system, including insulation wrap and top plate.
How we do it
We measure the flue with a video scan, drop a continuous 316Ti stainless liner with corrugated flex sections for offsets, pack it with ceramic blanket insulation, and terminate with a UL-listed top plate and rain cap.
Partial Rebuild
Signs you need it
Spalled brick above the roofline, a leaning chimney stack, or mortar joints eroded to finger-depth while the lower structure remains sound.
What it costs in Westminster
Partial rebuild from the roofline up in Westminster typically runs $3,500-$6,500 depending on brick matching and scaffold requirements.
How we do it
We dismantle to sound masonry, salvage matching brick when possible, pour a new reinforced crown, rebuild to original dimensions, and flash with step and counterflashing integrated to your roof system.
What Chimney Liner & Rebuild Costs in Westminster
| Item | Typical range in Westminster |
|---|---|
| Stainless steel liner (single flue, installed) | $2,800 - $4,500 |
| Flexible liner with offset capability | $3,200 - $5,000 |
| Partial rebuild (roofline up) | $3,500 - $6,500 |
| Full chimney rebuild | $8,000 - $15,000 |
Does a liner replacement require a permit in Westminster?
Yes. Adams County classifies liner replacement as alteration of a combustion venting system; we pull the permit, schedule inspection, and include all fees in your written quote. The permit process typically adds 3-5 business days to scheduling.
Can I just patch the liner instead of replacing it?
Localized cracks sometimes qualify for HeatShield cerfractory resurfacing at $1,800-$2,800, but we only recommend it for damage confined to the upper third of the flue with intact underlying structure. The camera scan determines eligibility; we show you the footage and explain why or why not.
Brands We Service in Westminster
We stock and install DuraFlex stainless liners, HeatShield cerfractory resurfacing products, and Gelco cap assemblies from our Denver office, with most Westminster jobs supplied within 24 hours. Olympia Chimney components are available for specialized prefab chase cover replacements. our brands
