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 Company in Westminster, CO
Most of the chimney work we do in Westminster isn’t new construction. It’s repair on chimneys that were built in the 1950s, ’60s and ’70s, fired hard with wood for decades, and later fitted with a gas log set or an insert without anyone relining the flue. That gap is where cracked tiles, glazed creosote and rusted caps come from. Westminster’s high-desert freeze-thaw cycle between November and March works on the same masonry, stressing crowns and mortar joints year after year. We handle the whole flue, from the first sweep to a full reline. Call (855) 360-7080 for a free estimate.
Why Westminster Homes Are Different
Westminster sits in the pre-1970s suburban belt between Denver and Boulder, and that single fact shapes nearly every job here. Thousands of homes in the original Westminster townsite went up with a masonry firebox and a clay-tile flue that was never intended to vent a modern insert or a converted gas log set. The flues are still the originals in many of those houses. They’ve been heated and cooled for 50 to 70 years, and clay tile doesn’t flex.
The climate adds its own pressure. Front Range winters swing hard between cold and mild, and that freeze-thaw cycling opens hairline cracks in mortar joints and crowns, then widens them. Occasional high-wind events along the corridor loosen creosote from older flue walls and push downdrafts down chimneys that vent poorly to begin with. Winter heating-season use is heavy here, so creosote accumulates fast.
The spread of the city matters too. The 80030 and 80031 ZIP codes carry the original mid-century ranches and split-levels with the oldest flues and the heaviest creosote loads. The newer construction out toward the Boulder Turnpike corridor is a different animal altogether, usually metal flues and factory-built fireplaces with their own service needs. One company, two very different sets of problems.

Our Main Westminster Services
Two jobs come up again and again in Westminster: evaluating and repairing old flues before another heating season, and clearing the dryer vents in the same houses.
Chimney Sweep in Westminster
A sweep in the older Westminster core is rarely just a sweep. Technicians routinely find the original 1950s and ’60s spark-arrestor caps rusted and seized onto the clay tile, and flue walls carrying glazed, stage-3 creosote from the pre-EPA-stove decades. We run a camera down the flue and show you what’s there before we recommend anything. That evidence is what separates a needed repair from a guess. If you want the full picture on a standard cleaning and inspection, Chimney Sweep in Westminster covers what we check and how the visit runs.
Dryer Vent Cleaning in Westminster
Lint buildup in a dryer vent is a genuine fire hazard, and most chimney-only companies won’t touch it. In a mid-century Westminster ranch, the dryer often sits far from the exterior wall, which means a long duct run with bends where lint collects and airflow drops. We clear the full run and check the exterior termination for a stuck damper or a screen packed solid. It’s a straightforward job that finishes in one visit. The full rundown is on our Dryer Vent Cleaning in Westminster page.
Chimney Repair in Westminster
Chimney repair in Westminster is mostly about the original masonry flues in the pre-1970s core, where clay tile has cracked, spalled or shifted and the firebox has been retrofitted with gas logs or an insert without a matching reline. The dry winters and hard freeze-thaw cycling between November and March open mortar joints and crowns, so water gets in and the damage compounds. We handle all of that under Chimney Repair, from a single cap to a full flue rebuild.
Chimney Liner Installation
Signs you need it
You need a liner if a camera inspection shows cracked, spalled or offset clay tiles, if the flue was never sized for the insert or gas appliance now venting into it, or if combustion gases are escaping into the house.
What it costs in Westminster
A typical liner installation in Westminster runs $3,000 to $4,500, and the written estimate sets the final price.
How we do it
We measure and camera the flue, size the correct liner to the appliance, then install a DuraFlex flexible stainless system with proper insulation and a top plate, and verify the fit with a final inspection.
Chimney Cap Replacement
Signs you need it
The cap needs replacing when the original spark arrestor is rusted through or seized onto the clay tile, when the mesh is torn, or when water is getting past it into the flue.
What it costs in Westminster
Chimney cap replacement in Westminster usually falls between $300 and $600, depending on the flue size and cap style.
How we do it
We free the seized old cap without damaging the tile, measure the flue opening, fit a correctly sized stainless or Copperfield cap, and seal it to the crown.
What Chimney Repair Costs in Westminster
These are typical ranges for the repair work we see most often in Westminster. Every job is quoted in writing before anything starts.
| Item | Typical range in Westminster |
|---|---|
| Chimney cap replacement | $300 – $600 |
| Chimney crown repair | $400 – $900 |
| Chimney liner installation | $3,000 – $4,500 |
Do I really need a new liner, or can it be resurfaced?
Sometimes it can be resurfaced. If the clay tile is sound but the inner face is pitted or has gaps at the joints, HeatShield resurfacing can restore the flue without a full reline, at lower cost. If the tile is cracked through or offset, a new liner is the right call.
Will a repair fix a downdraft problem in my Westminster home?
Often yes. High-wind events here push air down poorly terminated flues, and a rusted or undersized cap is a common cause. We camera the flue and check the cap and crown first, because those two fixes solve most downdraft complaints without a bigger repair.
Brands We Service in Westminster
We install and work with professional-tier products, not hardware-store substitutes: DuraFlex flexible liners, HeatShield resurfacing, Famco and Copperfield caps and components. If a part is needed, we tell you the brand and the reason before we order it. Turnaround depends on the part, and we give you a date when we quote. You can read more about our brands.

What Westminster Customers Say
"Swept it, capped it, and installed a proper damper. The downdraft smell in the summer that we'd lived with for years is gone."
- Adam Kowalski"Crown was cracked and taking water. Repaired it rather than quoting a rebuild, which the previous company had pushed hard for."
- Holly Reed"Creosote buildup was worse than I realized. He measured it, showed me the glazing on the flue with the camera, and was honest that we were closer to a chimney fire than I wanted to hear."
- Allison Gallagher
