A chimney sweep in Greeley will tell you the best way to prevent animals nesting in your Dacono chimney is to combine physical barriers (like caps and screens) with routine inspections, especially before fall migration season. Start with a chimney inspection to check for gaps, then install a chimney cap (costing $150–$400) and schedule a sweep twice yearly. If you spot nests or debris, act fast: animals like raccoons or birds can cause $1,000+ in damage if left unchecked.
Why Dacono Chimneys Are Magnetizing to Animals (And How to Stop It Early)
Dacono’s semi-arid climate and older brick homes, common in neighborhoods near Greeley’s city limits, create the perfect storm for animal nesting. The dry, windy conditions leave chimneys vulnerable to cracks, while the lack of dense foliage (unlike Windsor’s tree-lined streets) means fewer natural deterrents. Raccoons, birds, and even squirrels see your chimney as a cozy, draft-free den, especially if it’s been neglected since last winter.
The key to prevention? Catch signs before animals move in. A chimney sweep in Greeley will often find nests during routine cleanings, but by then, the damage (chewed liners, blocked flues, or even structural harm) can cost $500–$2,000 to repair. Instead, focus on these three early-warning steps: 1. Inspect your chimney cap (or lack thereof) after storms. Dacono’s spring hail can dislodge caps, leaving gaps the size of a softball. 2. Listen for scratching or chirping in the flue, especially at dawn or dusk. Birds and bats are most active during these hours. 3. Check for debris in your fireplace after a chimney sweep, feathers, twigs, or droppings mean animals are already using it as a highway.
Pro tip: If you’ve noticed more sparrows around your Fort Lupton-side home this spring, they’re likely scouting chimneys. The EPA’s Burn Wise program the EPA's Burn Wise program notes that birds often return to the same nesting sites year after year, so act now before migration peaks in late August.
For a chimney sweep near me that specializes in animal prevention, ask about stainless steel mesh screens (installed during a sweep for ~$200–$350) or brick-and-mortar repairs to seal cracks. These are far cheaper than removing a full nest later, especially if it’s a raccoon (their droppings alone can contaminate your home’s air quality). Background in our service list.
A Chimney Inspection Is the First Line of Defense: Here’s What Greeley Pros Look For
A chimney inspection isn’t just a box to check before lighting your first fire of the season. In Dacono, where homes near Greeley’s airport run older masonry, inspections reveal hidden entry points animals exploit. Here’s what a licensed chimney sweep in Greeley examines during a Level 2 inspection (the gold standard for animal risk):
- Crown cracks: The mortar between bricks on your chimney’s top (the crown) often erodes first. A 1/4-inch gap is enough for a squirrel to squeeze through. Cost to repair? $300–$800, depending on the size. - Damaged caps: Caps with missing or bent sections are like open invitations. Stainless steel caps (the best for Dacono’s wind) cost $150–$400 installed. - Liner gaps: Animals chew through single-wall metal liners in weeks. If your liner is older than 10 years, it’s a red flag, chimney liner installation in Greeley averages $1,200–$3,500 for a full reline. - Debris buildup: Leaves, mud, or animal nests in the flue reduce draft by up to 40%, forcing smoke into your home. A chimney sweep removes this and seals potential entry points.
When to schedule? The Chimney Safety Institute of America (CSIA) recommends inspecting before fall migration (late August) and after winter storms (which can dislodge caps). In Milliken or Platteville, where homes sit closer to open fields, inspections are even more critical, animals have fewer barriers to explore your chimney.
DIY check: Use a flashlight and mirror to peer up your flue from the fireplace. If you see daylight through cracks or hear rustling, book a chimney sweep Greeley immediately.

DIY Animal Prevention: 3 Steps Dacono Homeowners Can Do Before Calling a Chimney Sweep
Not every chimney needs a full sweep to deter animals. If you’ve spotted feathers near your fireplace or heard scratching in the flue, try these three DIY steps to buy time until your chimney sweep arrives:
1. Install a chimney cap with a screen: - Choose a stainless steel cap with a 1/4-inch mesh screen (animals can’t squeeze through, but smoke escapes). Brands like Chim-Top or Yader work well for Dacono’s wind. Cost: $100–$250 for materials; DIY installation takes 1–2 hours. - Pro move: Add a weighted cap if your chimney is tall (common in Johnstown’s historic homes), wind can lift lighter caps during Greeley’s spring storms. - Warning: Never use a cap with gaps larger than 1/2 inch, squirrels and birds will still nest inside.
2. Seal small cracks with high-temperature mortar: - For crown cracks under 1/2 inch, use refractory mortar (available at hardware stores). Apply it with a trowel, then let it cure for 48 hours. Cost: $20–$50 for materials. - For larger gaps: Use expanding foam sealant rated for 2,000°F+ (like 3M High Temp Sealant). This buys time until a chimney sweep can perform permanent repairs.
3. Create a physical deterrent: - Hang aluminum pie pans or wind chimes near the chimney top, animals dislike the noise and movement. Cost: $10–$20. - For birds: Install spike strips (plastic or metal) around the chimney crown. Cost: $15–$40 for a set.
When to call a pro: If you find live animals (even dead ones), nesting materials deeper than 6 inches, or structural damage, stop DIY efforts and schedule a chimney sweep near me. Animals like raccoons can carry diseases like leptospirosis, and their droppings contaminate your home’s air the U.S. Environmental Protection Agency. Our team in Dacono uses humane removal methods and includes a post-removal inspection to ensure no gaps remain.
Local note: If you’re in a fire-prone area near Firestone, prioritize animal prevention, nesting debris is a major fire hazard. The National Fire Protection Association (NFPA) the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) reports that chimney fires linked to animal nests increase by 30% in dry seasons like Greeley’s.
The Cost of Ignoring Animal Nesting in Your Chimney (And How Greeley’s Climate Makes It Worse)
Dacono’s dry, windy climate turns chimney neglect into a ticking time bomb. Here’s what happens when you ignore animal nesting, and the real costs Greeley homeowners face:
| Problem | Short-Term Cost | Long-Term Cost | Greeley-Specific Risk | |---------------------------|---------------------------|----------------------------------|---------------------------------------------------| | Bird nest in flue | $150–$300 (removal + sweep) | $500–$1,200 (liner damage) | Sparrows return yearly; nests block 50%+ draft. | | Raccoon den | $200–$400 (removal + cap) | $1,500–$3,000 (structural repair) | Droppings contaminate air; chewed liners fail in winter. | | Squirrel nest | $100–$250 (sweep + screen) | $800–$2,000 (relining) | Gnawed masonry weakens chimneys in Fort Lupton’s older homes. | | Bat colony | $300–$600 (humane removal) | $2,000–$5,000 (full rebuild) | Guano buildup corrodes flues faster in Greeley’s humidity. |
Why Greeley’s climate accelerates damage: - Wind: Dacono’s average 10 mph winds Greeley, CO dislodge caps and widen cracks, giving animals easier access. - Dry air: Low humidity means creosote (a chimney fire hazard) dries into hard, flammable layers, faster when nests block airflow. - Seasonal migration: Animals like mourning doves arrive in Platteville by late August. If your chimney is unguarded, they’ll nest before you know it.
Prevention pays off: A chimney sweep Greeley costs $120–$250 for a basic cleaning, but adding a cap or screen during the visit keeps animals out for years. Insurance tip: Most homeowners’ policies won’t cover animal-related chimney damage, only preventive maintenance (like annual sweeps) is reimbursable.
Act now: If your last chimney sweep was over a year ago, schedule one before September 15th, that’s when animal activity peaks in Northern Colorado. Use our free estimate tool (Get a Free Chimney Inspection Estimate) to lock in fall pricing.
Chimney Caps vs. Screens: Which Dacono Homeowners Need (And Why Greeley Pros Recommend One Over the Other)
Not all chimney caps and screens are created equal, and choosing the wrong one can invite animals back. Here’s how to pick the right solution for your Dacono home:
- Chimney caps (best for most Greeley homes): - Why? Caps block animals while allowing smoke to escape. Stainless steel caps (rated for 1,200°F+) are ideal for Dacono’s wind and snow loads (common in Evans’ higher elevations). - When to choose: If your chimney has no major cracks and you want a permanent solution. - Cost: $150–$400 installed by a chimney sweep. - Local tip: Ask for a double-mesh cap, it deters birds better than single-layer models.
- Chimney screens (best for damaged or historic chimneys): - Why? Screens (like Chim-Tex) fit inside the flue and prevent nests without altering your chimney’s exterior. They’re ideal for older brick chimneys in Milliken or Johnstown where mortar is crumbling. - When to choose: If your chimney has large gaps or you’re avoiding roof work. - Cost: $200–$500 installed (often combined with a sweep). - Warning: Screens reduce draft slightly, only use them if your chimney passes a smoke test first.
- Hybrid approach (best for high-risk homes): - Install a cap and a screen during your chimney sweep. This is overkill for most homes but worth it if: - You’ve had repeated animal visits. - Your chimney is older than 50 years (common in Windsor’s historic district). - You burn high-moisture wood (like oak), which increases creosote buildup, a magnet for insects.
Greeley-specific recommendation: If you’re in a fire-prone zone (like near Firestone), opt for a spark arrestor cap ($200–$500). It stops embers while keeping animals out, critical for homes with wood shake roofs.
DIY vs. pro install: While you can install a cap yourself, chimney sweeps ensure it’s level and sealed, critical for Dacono’s wind. We’ve seen improperly installed caps blow off during April storms, leaving chimneys wide open.

What to Do If You Already Have Animals in Your Chimney (And How to Avoid a Repeat)
Finding a nest in your chimney is a homeowner’s worst nightmare, but Greeley’s chimney sweep teams handle it daily. Here’s the step-by-step response plan for Dacono homeowners:
1. Do NOT attempt removal yourself: - Animals like raccoons are aggressive when cornered. Never poke a stick up the flue or use traps, this can cause them to bite through liners or damage masonry. - Humane removal by a pro costs $200–$600 but prevents $1,000+ in repairs from DIY mistakes.
2. Call a licensed chimney sweep immediately: - Our team uses carbon monoxide detectors to check for gas leaks (common after animal tampering) and thermal imaging to spot hidden nests. - Cost: $250–$500 for removal + inspection (often bundled with a sweep).
3. Seal entry points permanently: - After removal, we pressure-wash the flue to remove droppings (critical, bat guano can corrode liners in weeks) and install stainless steel mesh or a new cap. - Pro tip: Ask about chimney liner inspection, animals often chew through weak spots, creating hidden fire hazards.
4. Monitor for 30 days: - Animals return to familiar spots. Set up a motion-activated camera ($30–$80) near your chimney to catch repeat offenders.
Preventing a repeat: - Schedule a sweep every 6 months (fall and spring) to catch early signs. - Install a solar-powered deterrent light ($50–$100) near the chimney top, animals avoid bright areas. - Check your cap after storms. Dacono’s spring hail can damage even sturdy caps.
Local success story: A Platteville homeowner called us after finding a raccoon family in their chimney. We removed them, relined a chewed section ($1,800), and installed a heavy-duty cap. Total cost: $2,500. Without intervention, the raccoons would’ve caused $5,000+ in structural damage by winter.

Frequently Asked Questions
My Dacono home’s chimney has a small hole near the base, could a squirrel get in, and how do I stop it?
Yes, a 1/2-inch gap is enough for a squirrel to enter. Seal it with high-temperature expanding foam ($20) or refractory mortar ($30). For larger holes, call a chimney sweep Greeley to patch it permanently. DIY fixes often fail after Greeley’s winter freeze-thaw cycles. If you’ve seen shredded nesting material in your fireplace, animals are already inside.
I heard birds chirping in my chimney last night near my Evans home, what’s the fastest way to get them out?
Birds are most active at dawn. Hang aluminum pie pans near the chimney top to deter them, then schedule a chimney sweep near me to remove nests and install a screened cap. Never use mothballs or ammonia, these are illegal in Colorado and harm wildlife. A pro can remove nests in 1–2 hours and ensure no eggs remain (which would attract more birds).
Are chimney caps worth the cost in Dacono’s windy climate, or will they just blow off?
Stainless steel caps designed for high winds (like Yader’s WindGuard) stay in place during Greeley’s 40+ mph gusts. A properly installed cap costs $150–$400 and prevents 90% of animal entries. Cheaper caps (under $100) often fail, we’ve seen DIY caps ripped off in April storms, leaving chimneys wide open. Ask your chimney sweep to secure it with stainless steel screws for extra hold.
My chimney was swept last year, but I’m worried about animals nesting in the crevices, how often should I check it?
Check your chimney monthly for debris, especially after spring storms (which dislodge nests) or fall migration (when birds arrive). If you’ve had animals before, install a cap and screen during your next chimney sweep Greeley, this reduces checks to twice yearly. Listen for scratching or flapping in the flue; these are early signs before nests become visible. Greeley’s dry climate means nests dry out faster, increasing fire risk.
