Before your Denver chimney sweep arrives, clear debris from the fireplace and hearth, remove any stored items near the chimney, and check for obvious damage. Never attempt to climb on the roof or remove creosote buildup yourself, these tasks require professional training to avoid carbon monoxide risks or structural damage. Focus only on what’s safe and visible from the ground.
What Denver Homeowners Get Wrong About Prep: The Myth of ‘Quick Fixes’
Many Denver homeowners assume they can speed up their chimney sweep by doing a ‘quick clean’ themselves. This is dangerous. While you can safely remove large debris like fallen leaves or twigs from the fireplace opening, never use a vacuum, wire brush, or any tool inside the flue, these can damage the liner or spark a fire. Instead, focus on clearing the hearth area and ensuring pets or kids stay away during the appointment. Denver’s dry climate means creosote buildup happens faster than in wetter areas, so even small DIY mistakes can create hidden hazards. Read our Denver-specific chimney safety tips here to spot problems before they escalate.
Step-by-Step Safe Prep: What You Can Do Before the Chimney Sweep Arrives
1. Clear the fireplace and hearth: Remove any ash, soot, or debris from the firebox and hearth. Use a metal bucket or dustpan, never sweep directly into the flue. 2. Move stored items: Keep firewood, decorations, or tools at least 3 feet away from the fireplace opening. 3. Check for loose items: Secure any wobbly screens or glass doors. 4. Note recent use: If you’ve used the fireplace in the last 24 hours, let it cool completely before the sweep arrives, hot chimneys slow down inspections and pose burn risks. 5. Document concerns: Jot down any changes you’ve noticed, like stronger smoke smells or soot around the damper. This helps the technician prioritize their inspection. Learn how often Denver chimneys need service to stay ahead of maintenance.
‘I can handle this myself’, but these Denver-specific red flags mean your fireplace is a ticking time bomb
If you see any of these during your prep, cancel DIY tasks and contact Lizard Chimney Inc immediately: rust or water stains on the chimney breast or ceiling (signs of a leak), cracked or missing mortar in the flue (common in older Denver homes with brick chimneys), white powdery residue on the hearth (a sign of flue gas escaping, carbon monoxide risk), or animals nesting in the chimney (rodents or birds create blockages). Denver’s high altitude and windy seasons accelerate these issues. See our guide on chimney repairs vs. replacements to understand why some problems can’t wait. If your chimney is over 20 years old, even minor damage may require professional assessment.
‘My brick fireplace looks fine’, but DIY repairs in older homes near I-25 could turn your hearth into a fire risk
Avoid these common mistakes that void warranties, create liability risks, and can lead to house fires: Climbing on the roof to inspect or clean the chimney (Denver’s steep roofs and icy winters make falls deadly). Chemical flue cleaners don’t just fail, they eat away at your chimney liner and pump poisonous gas into your home Ignoring a blocked damper (this traps smoke and carbon monoxide inside your home). Skipping annual inspections for gas fireplaces (Denver’s thin air increases combustion risks). Our gas fireplace safety guide covers why these systems need specialized care. If you’re unsure, err on the side of caution, chimney work isn’t just about cleaning; it’s about structural and safety integrity.

Frequently Asked Questions
My Denver home’s chimney is over 30 years old, should I prep differently before the sweep?
Yes. Older chimneys in Denver often have deteriorated mortar or cracked liners, which require extra caution. Focus on clearing debris from the fireplace only, never attempt to probe the flue or roof. If you notice crumbling bricks or rust stains near the base, document these for the technician. Older systems also need more frequent inspections; our Denver chimney inspection guide explains why Level 2 or 3 inspections may be needed. Never skip prep just because the chimney is old, hidden hazards worsen with age.
I live near the foothills in Golden, does Denver’s high altitude affect chimney prep?
Absolutely. Denver’s thin air and higher elevations mean fireplaces burn hotter and produce more creosote faster, especially in areas like Golden. Before your sweep, check for excessive soot buildup in the firebox, this is normal but requires professional removal. Also, ensure your damper opens and closes smoothly; altitude can cause draft issues. Our Golden service area includes technicians trained to handle these unique conditions. If your fireplace struggles to draw, this could signal a blocked or improperly sized flue, never ignore it.
Can I use my fireplace after the chimney sweep if it’s still smoky?
No. If smoke lingers after the sweep, it means the flue isn’t drawing properly, this could be due to creosote buildup higher up, a blocked damper, or even a cracked liner. Using the fireplace in this state risks carbon monoxide poisoning or a chimney fire. Wait for the technician’s approval, especially in Denver’s windy seasons where drafts can change suddenly. Our Thornton service page highlights how local weather affects chimney performance. If the issue persists, schedule a Level 2 inspection to diagnose the root cause.
