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 Welby, CO
Chimney repair in Welby is a different job than it is a few miles south in Denver. Most of the housing here is older post-war and 1960s-70s tract stock, and a lot of those chimneys were built for appliances people no longer use. When we open one up, we’re usually looking at aging masonry or an early prefab metal flue that has seen several decades of short, cold winters. Our technicians have up to 10 years of experience with exactly this kind of setup, and we carry the repair materials to fix what a sweep turns up. Call (866) 361-5660. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
Welby is one of those unincorporated pockets where a lot of the housing is modest and older, and the chimney was never the showpiece. That’s fine by us. It’s the working chimney we know best.
Why Welby Homes Are Different
Welby sits in an unincorporated pocket of Adams County between Denver and Thornton, along the I-25 and Highway 36 corridor. The housing mix tells you most of what you need to know about the chimney work. Much of it is older post-war and 1960s-70s tract housing in the 80221 ZIP, single-family and small multifamily, and a good share of it is rented. That means a sweep here often doubles as documentation for insurance or a lease turnover, and the technician has to write down what was found, not just run a brush and go.
The second wrinkle is what those chimneys were originally built for. Some served coal-era setups or early gas appliances and were adapted later, which sometimes leaves an undersized or completely unlined flue. A routine sweep can turn into a real conversation about lining.
The Front Range climate concentrates the work too. Winters are cold and dry with the occasional downslope wind event, so fireplace use presses into a short season and calls stack up in fall. Dry windy stretches raise creosote and downdraft concerns on flues that were never quite right to begin with. We plan for that when we schedule Welby work in late summer and early autumn.

Our Main Welby Services
Two jobs come up again and again in Welby: cleaning the flue before the heating season and getting the venting sorted out behind the dryer. Both run through one specialist here.
Chimney Sweep in Welby
A sweep in Welby rarely ends at the brush. On older 80221 homes, technicians often pull creosote and soot from a flue that was built for an appliance the homeowner never used, which means the inspection matters as much as the cleaning. We run the brush, then check the firebox, damper, cap and the flue itself for cracks, gaps or missing liner sections that dry windy weather can expose. Rental properties get clear written documentation for the landlord or insurer. For a full breakdown of what a visit covers, see Chimney Sweep in Welby. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
Dryer Vent Cleaning in Welby
Dryer vent cleaning is its own job, not an add-on at the end of a sweep. In older tract homes the vent run is often longer than it should be, routed through a wall or under a floor, and lint builds up where nobody can see it. That’s a fire risk most chimney-only providers never touch. Our technicians clear the run, verify the exterior termination, and confirm the airflow is actually moving. On small multifamily buildings in Welby, each unit’s vent gets handled separately. For the full picture, see Dryer Vent Cleaning in Welby.
Chimney Repair in Welby
Chimney repair is the work Welby calls us for most, and it’s the work that surprises homeowners. Plenty of the chimneys here were built decades ago for coal or early gas and adapted later for wood or a gas insert, so what looks like a straightforward cleaning often reveals an undersized or unlined flue that needs a liner before the next fire. The short, dry Front Range heating season means damage accumulates slowly between uses, which is exactly why a spring inspection is worth doing. We handle Chimney Repair in-house, so a problem found during a sweep can be specified and fixed rather than handed to a separate masonry contractor.
We work with DuraFlex liner systems and HeatShield resurfacing because those materials are specified for the flue in front of us, not because they’re the cheapest thing on the shelf. That matters on older Welby chimneys, where the flue dimensions were set long before anyone thought about modern appliance ratings.
Chimney Liner Installation
Signs you need it
Look for a flue with no liner at all, visible cracks or gaps in a clay tile, or a gas insert vented into a flue that was sized for a wood fire and never corrected.
What it costs in Welby
Relining in Welby typically runs $2,400 to $5,800, depending on flue length and whether a full stainless system or a HeatShield resurfaced interior is the right answer.
How we do it
We measure the flue, camera-inspect it to confirm the interior, then specify the DuraFlex liner or HeatShield resurfacing to match, install it, and verify draft before we leave.
Chimney Cap Installation
Signs you need it
An open flue with no cap lets rain, debris and downdrafting wind straight into the chimney, which is a real problem on Welby’s exposed Front Range elevation.
What it costs in Welby
A cap installed in Welby usually falls between $180 and $420, and stainless or multi-flue caps sit at the higher end.
How we do it
We size the cap to the flue opening, set it on the crown with proper anchoring, and check that it vents correctly without restricting draft.
Chimney Crown Repair
Signs you need it
A cracked or crumbling concrete crown lets water into the masonry, which shows up as spalling brick, rust stains or a damp firebox after a storm.
What it costs in Welby
Crown repair in Welby typically runs $350 to $900, with full crown rebuilds at the top of that range.
How we do it
We chip out the failed concrete, reform the crown with the correct slope away from the flue, and seal the joint where the flue meets the crown.
What Chimney Repair Costs in Welby
| Item | Typical range in Welby |
|---|---|
| Chimney liner installation | $2,400 – $5,800 |
| Chimney cap installation | $180 – $420 |
| Chimney crown repair | $350 – $900 |
Does Welby require a permit to reline a chimney?
It depends on the scope and the inspector, so ask the Adams County building department before work starts. Liner replacements usually need a permit; caps and minor crown work often don’t. We tell you which category your job falls into when we quote it. Call (866) 361-5660 for an exact quote – estimates are free.
Can an old Welby chimney be brought up to current code without a rebuild?
Often yes. HeatShield resurfacing can restore a compromised clay flue interior without removing masonry, and a DuraFlex liner handles cases where the flue is too damaged to resurface. Neither works if the chimney structure itself is failing, which is what the camera inspection checks first. Call (866) 361-5660 for an exact quote – estimates are free.
Brands We Service in Welby
We work with Gelco, Olympia Chimney, Famco and Copperfield products, specified for the flue rather than pulled off a truck. Because these are the brands chimney specialists rely on, turnaround on most repair parts is measured in days, not weeks. For the full lineup, see our brands.

What Welby Customers Say
"Thorough sweep and a clear report. He was running late from the job before and arrived near the end of the window, though he did call to warn me."
- Tara Schaefer"Fireplace had never drawn properly since we moved in. He found the damper was only opening halfway due to a bent linkage and fixed it in ten minutes."
- Todd Meyer"Liner was cracked in two places. He walked me through the repair options honestly, including the one that was cheaper for him and better for me."
