DIY chimney sweeping in Arvada is risky for Broomfield’s older brick homes because it misses creosote buildup in hard-to-reach liner joints, ignores cracked masonry that worsens with moisture, and can’t safely remove stubborn tar deposits. A licensed chimney sweep uses specialized tools to clean liners, inspect brickwork, and spot hidden hazards, saving you from chimney fires, carbon monoxide leaks, and repair costs that often exceed $1,000. Always hire a pro for safety and longevity.
A chimney sweep is a thorough cleaning and inspection of your chimney’s flue, liner, and masonry, done by a certified professional with tools that reach every crevice.
In Arvada, many homes near Broomfield’s older neighborhoods (like those built in the 1920s–1950s) have brick chimneys with clay or metal liners that degrade over time. A true chimney sweep isn’t just shoving a brush up the flue, it’s using a rotating brush system, vacuum, and camera inspection to remove creosote (the flammable tar left by wood burning), check for liner cracks, and assess masonry for spalling or mortar failure. Cheap brushes and hardware-store rods might clear some soot, but they’ll leave creosote and hidden damage behind in your Broomfield brick chimney’s joints and mortar. They leave behind creosote in hard-to-reach corners, especially where the liner meets the brickwork, which is a fire hazard the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)). In Broomfield, we’ve seen DIY attempts turn into $3,000+ repair bills when hidden creosote ignites or moisture seeps into unsealed brick joints.
For example, a home on 10th Street in Broomfield had its chimney partially cleaned with a wire brush, but the crew missed the second-story liner joint where creosote had built up for years. When the homeowner lit a fire, the chimney caught fire, damaging the crown and requiring a full reliner job. A professional sweep would’ve caught that during the inspection, and saved thousands. If your home was built before 1980, the brickwork alone might need repointing or tuckpointing, which DIYers can’t safely do without risking structural damage.

Creosote isn’t just soot, it’s a stage 1–3 fire risk, and DIY tools can’t remove it all from older liners.
Creosote forms when wood burns incompletely, leaving behind a sticky, flammable residue that coats your liner. There are three stages: - Stage 1 (glazed): Shiny, tar-like. DIY brushes might remove some, but it’s already a fire risk. - Stage 2 (tar-like): Thick and crumbly. A wire brush can push it deeper into liner cracks. - Stage 3 (hard, brick-like): Only a professional with a rotating brush and vacuum can remove it safely.
In Broomfield’s dry climate, creosote dries faster and becomes more dangerous. We’ve pulled out liners encased in stage 3 creosote, homeowners thought their DIY sweep was enough, but the real buildup was hidden behind the visible soot. The NFPA the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) reports that creosote causes 25% of chimney fires, and most start in homes where sweeping was skipped or done improperly. If your chimney has a single-wall liner (common in older homes), creosote can seep into the surrounding brickwork, weakening mortar and leading to costly repairs. A professional sweep will pressure-wash the liner to remove all residue and inspect for cracks where moisture could enter. See how often you should sweep based on your fuel type.
Broomfield’s brick chimneys hide moisture problems DIY sweeps miss, leading to $1,500+ repair bills.
Older brick chimneys in Broomfield (especially those near Evergreen Parkway or the Broomfield Enterprise zone) absorb moisture from snowmelt, rain, and even humidity. If your sweep doesn’t check for: - Spalling brick: Flaking or crumbling due to freeze-thaw cycles (common in Broomfield’s winters). - Cracked mortar joints: Letting water seep into the flue and corrode the liner. - Missing or damaged chimney caps: Letting rain directly into the flue.
A DIY sweep won’t spot these issues because they require climbing onto the roof and inspecting the masonry up close. We’ve seen chimneys where water damage had rotted the wood framing inside the home, costing homeowners $2,000–$5,000 to replace. The EPA the U.S. Environmental Protection Agency notes that moisture is the #1 cause of chimney liner failure, and a professional sweep will seal cracks with high-temperature mortar or recommend a new liner if needed. Need a chimney cap or crown repair? Here’s why it’s urgent.
Should I hire a chimney sweep in Arvada if my fireplace feels ‘clean’?
Even if your fireplace looks clean, you still need a sweep, especially in Broomfield’s older homes. Here’s why: 1. Creosote is invisible until it’s too late. It builds up on the liner walls, not just the bottom. A DIY brush might remove surface soot but leave a fire hazard behind. 2. Older liners crack over time. Clay liners (common in pre-1980 homes) develop hairline fractures that trap creosote. A professional uses a camera to check for these. 3. Carbon monoxide (CO) is odorless. A blocked or poorly maintained chimney can leak CO into your home. The CSIA recommends annual inspections for safety, even if you don’t burn wood often.
In Arvada, we’ve had homeowners skip sweeps for years, only to discover their chimney was partially blocked by debris or animal nests, forcing a full reliner install. The average cost for a professional sweep in Broomfield is $120–$250, but the cost of a chimney fire or CO poisoning is far higher.

Is it worth the risk to DIY sweep my Arvada home’s chimney?
Short answer: No, not if your home has brick masonry or a liner older than 20 years. Here’s what you’re risking: - Chimney fire: DIY tools can’t remove all creosote, and a spark from your fireplace can ignite it. The NFPA reports chimney fires double in homes that haven’t been swept in over a year. - Carbon monoxide poisoning: A blocked or damaged liner can let CO into your home. Poor ventilation from a clogged chimney can cause dizziness, stomach issues, and exhaustion, symptoms homeowners often blame on seasonal bugs instead of their fireplace. - Masonry damage: Brushing too hard can dislodge mortar or crack bricks, leading to water damage and higher repair costs. - Void your insurance: Many policies require annual professional inspections to cover chimney-related claims. A DIY sweep won’t meet this standard.
For example, a homeowner in Arvada tried sweeping their chimney with a wire brush and a shop vac. They missed creosote in the liner joints, which later caused a fire that damaged the crown and required a $4,500 repair. A professional sweep would’ve caught it for $180. See how much a Broomfield chimney sweep costs and why it’s cheaper than repairs.
Even a low-heat kindling fire in a 1920s Craftsman’s masonry chimney can leave creosote buildup where a wire brush won’t reach, putting your liner and flue at risk.
Yes, even if you burn only kindling or gas logs, your chimney needs an inspection. Here’s why: - Gas fireplaces still need venting. A blocked or damaged liner can let carbon monoxide into your home, even with a gas unit. - Kindling burns hotter than you think. It creates more creosote than you’d expect, especially in older liners. - Animals and debris build up. Birds, squirrels, and leaves can block your chimney without you noticing. We’ve pulled out nests from chimneys where homeowners thought they were “safe” because they didn’t burn wood often.
The CSIA recommends annual inspections for all chimneys, regardless of fuel type. In Broomfield, we’ve seen gas fireplace chimneys fail because the liner was corroded from years of moisture, something only a professional inspection would catch. Learn the difference between a sweep and an inspection.
How much does a professional chimney sweep cost in Arvada vs. DIY tools?
Here’s the breakdown for a typical Broomfield home with a brick chimney and liner: | Service | DIY Cost (Tools Only) | Professional Cost (Arvada/Broomfield) | Hidden Risks if DIY Failed | |-----------------------|-----------------------|--------------------------------------|------------------------------------| | Basic sweep | $20–$50 (brush/vac) | $120–$200 | Chimney fire, CO poisoning | | Inspection + sweep | $0 (no tools) | $180–$280 | Undetected liner cracks | | Masonry repair | $0 (can’t fix) | $500–$2,000 | Water damage, brick spalling | | Reliner install | $0 (can’t do) | $1,500–$4,000 | Full chimney replacement needed |
DIY tools might seem cheap, but they don’t include the inspection, camera check, or masonry assessment a pro provides. For example, a home on 112th Avenue in Broomfield paid $30 for a brush and vac, then had to call us for an emergency reliner after a chimney fire. The total cost? $3,800. A professional sweep would’ve prevented it for $180. Get a free quote for your Arvada home to compare.

Frequently Asked Questions
Should I hire a chimney sweep in Arvada if my chimney looks clean but smells smoky?
Yes, smoke smell means incomplete combustion, which leaves creosote buildup even if the chimney looks clean. In Broomfield’s older brick homes, this often signals a blocked liner or cracked masonry, not just soot. A professional sweep will use a camera to check for hidden obstructions and inspect the brickwork for moisture damage. Ignoring it risks a chimney fire or CO leak. Learn how to prepare your chimney for a sweep.
Is it worth the risk to DIY sweep my Broomfield home’s chimney if I’m on a tight budget?
No. DIY sweeps in older brick homes often miss creosote in liner joints, which is a fire hazard. The average cost to repair a chimney fire in Broomfield is $2,500–$5,000, far more than a professional sweep ($120–$250). Plus, DIY tools can’t inspect for masonry cracks or CO risks. If budget is the issue, ask about payment plans or off-season discounts, many Broomfield sweeps offer them. See our pricing for Arvada homes.
Skipping inspections for your rarely used fireplace in a pre-1980s home with original brickwork means missing early signs of liner corrosion or mortar cracks, problems that worsen fast in Broomfield’s freeze-thaw cycles.
Absolutely, even occasional use lets moisture and debris build up. The CSIA recommends annual inspections for safety, especially in Broomfield’s older homes where brickwork and liners degrade faster. A pro will check for animal nests, liner cracks, and hidden creosote, all risks DIY misses. Skipping it could void your insurance if a chimney fire occurs. Schedule your inspection before winter.
How do I know if my Arvada chimney has a liner that needs replacing?
Look for these signs: rust stains on the fireplace hearth, excessive smoke in the room, or a musty smell. In older Broomfield homes, clay liners crack over time, and metal liners rust. A professional sweep will use a camera to confirm. If the liner is damaged, replacing it costs $1,500–$4,000, far cheaper than a chimney fire repair. Learn about liner benefits for older homes.
