A Weld County chimney sweep from Daniel Thompson Chimney Inc covers unincorporated areas like Johnstown and Platteville, plus nearby towns like Longmont and Erie. We offer comprehensive chimney cleaning, inspections, repairs, and carbon monoxide testing tailored to Boulder’s climate and your home’s needs.
1. Why Weld County homeowners trust us for chimney sweeping
A chimney inspection is a thorough check of your flue, liner, smoke chamber, damper, and exterior masonry to spot creosote buildup, cracks, or blockages before they become hazards. In Weld County, where homes range from historic farmhouses near Platteville to newer builds in Johnstown, creosote accumulates faster in wood-burning fireplaces due to Colorado’s dry air and seasonal temperature swings. We use CSIA-certified techniques and EPA-compliant equipment to remove every ounce of soot and glaze, not just the visible layer. Our crews also check for animal nests—squirrels and raccoons love Weld County chimneys in winter—and ensure your chimney cap is secure against wind and hail common in the Front Range. After your sweep, we provide a free estimate for any repairs and a detailed report you can share with your home inspector or insurance agent. services contact
2. Our Weld County coverage areas: From Johnstown to Platteville and beyond
We serve all of Weld County’s unincorporated areas, including Johnstown, Platteville, Gilcrest, and Garden Plain, plus nearby communities like Longmont, Erie, and Louisville. If your home is near Boulder’s foothills or along the St. Vrain Creek corridor, our crews know the local climate challenges—from sudden temperature drops that crack mortar to summer hail that damages caps. We also service Louisville, CO areas/louisville-co/, Longmont, CO areas/longmont-co/, and Erie, CO areas/erie-co/ with the same level of care. Need to confirm if we cover your street?

3. What’s included in our Weld County chimney sweep appointment
Your appointment starts with a free estimate and a walkthrough of your fireplace setup—whether it’s a traditional masonry chimney, a prefab zero-clearance unit, or a wood stove insert. We remove and clean the firebox, vacuum the flue from top to bottom, inspect the damper and smoke chamber, and check the exterior for mortar deterioration or missing bricks. If your chimney has a liner, we brush it thoroughly to remove creosote glaze that can ignite during Boulder’s dry winters. We also test your damper’s operation and recommend a cap or screen if yours is missing or damaged. After the sweep, you’ll get a digital report with photos and a clear list of any recommended repairs. pricing blog/boulder-chimney-inspections-types-costs-and-why-theyre-criti
4. How often should I schedule a chimney sweep in Weld County?
The Chimney Safety Institute of America recommends sweeping your chimney when creosote buildup exceeds 1/8 inch, which can happen in as little as two cords of wood burned in a season. In Weld County, we see homeowners with wood stoves burn through more fuel in winter, so we often recommend two sweeps per year—once before the heating season and once mid-season if usage is heavy. If you use your fireplace only occasionally, an annual inspection is enough, but still schedule a sweep if you notice smoke backing up into the room or a strong, acrid odor. tips/boulder-chimney-service-schedule ((the Chimney Safety Institute of America (CSIA)|https://www.csia.org/))
5. Can I use my fireplace right after a chimney sweep in Boulder?
Yes—once we finish cleaning and inspecting your chimney, your fireplace is safe to use immediately. We leave your firebox clean and clear of debris, and we ensure the damper opens and closes smoothly. However, if we found cracks in the flue liner or missing mortar joints, we’ll recommend repairs before your next burn to prevent heat transfer to nearby wood framing—a common issue in older Weld County homes. Always wait until the ashes are cool before closing the damper to avoid moisture buildup in your flue. blog/best-time-for-chimney-sweep-in-boulder
6. Our Weld County chimney services beyond sweeping: Inspections, repairs, and safety checks
Beyond sweeping, we offer Level 1, 2, and 3 chimney inspections tailored to your needs. A Level 1 inspection is standard for routine maintenance, while a Level 2 is required after a chimney fire, chimney relining, or when buying/selling a home in Weld County. We also perform chimney repairs, including crown sealing, liner installation, and tuckpointing for cracked mortar joints common in Boulder-area brickwork. For added safety, we provide carbon monoxide testing and install or replace chimney caps to keep out debris and critters. Whether your home is in Johnstown or near the Flatirons, we tailor our services to your chimney’s age, material, and usage. compare/repair-vs-replace-chimney/ blog/boulder-chimney-repairs-common-issues-costs-and-when-to-call
7. How to prepare for your Weld County chimney sweep appointment
Clear a 3-foot path around your fireplace and move any furniture or decor that could get dusty. If you have a gas fireplace, turn off the pilot light and note the location of your gas shutoff valve. For wood-burning setups, remove ashes down to the firebox floor—we’ll handle the rest. If your chimney has a screen or spark arrestor, have it ready so we can inspect it for rust or damage. Finally, let us know if you’ve noticed unusual odors, draft issues, or animals entering the flue. We’ll take care of the rest. tips/how-to-prepare-for-your-chimney-appointment-in-boulder

Frequently Asked Questions
My Boulder home has a wood stove insert—do I still need a chimney sweep in Weld County?
Yes. Wood stove inserts still rely on a chimney flue to vent gases safely. Creosote builds up inside the flue just as it does in a masonry chimney, and the NFPA warns that even small amounts can ignite. Schedule an annual sweep and inspection to keep your stove running efficiently and safely. blog/golden-co-chimney-sweeping-seasonal-tips-homeowners
Why does my Erie, CO chimney smell like a campfire even when I haven’t burned anything in weeks?
That campfire odor is likely creosote residue trapped in your flue. When outdoor temperatures drop at night, the flue cools and draws in outside air, carrying the smell downward. A professional sweep removes the glaze and residue, and installing a stainless-steel liner or cap can prevent future odors. We see this often in older Erie homes with unlined chimneys. blog/broomfield-co-carbon-monoxide-testing-why-its-non-negotiable
I’m buying a home in Johnstown, CO—what chimney questions should I ask the inspector?
Ask for the chimney’s age, liner type, and the date of the last sweep and inspection. Request photos of any cracks, missing mortar, or creosote buildup. Also ask if the inspector checked for water damage, which is common in Weld County due to freeze-thaw cycles. A Level 2 inspection is ideal for older homes or if the seller hasn’t provided recent records. blog/boulder-chimney-inspections-types-costs-and-why-theyre-criti
Can I DIY my Weld County chimney sweep, or is a pro really necessary?
While you can brush the firebox and remove ashes, a professional sweep uses specialized brushes, vacuums, and cameras to clean the entire flue safely. The CSIA warns that improper DIY cleaning can push creosote deeper into cracks or damage flue liners. Plus, we spot hazards like cracked crowns or missing caps that a homeowner might miss. compare/diy-vs-professional-chimney-cleaning/
