Carbon monoxide poisoning in Golden homes usually starts with a failing chimney liner, cracked brickwork, or a blocked flue, common in older brick homes. The fix? A professional chimney sweep checks for gaps, seals leaks, and ensures proper airflow. Book one before winter to avoid deadly gas buildup.
What is carbon monoxide poisoning in Golden homes?
Carbon monoxide (CO) poisoning in Golden’s older brick homes happens when combustion gases, like those from fireplaces, furnaces, or water heaters, can’t escape through a damaged chimney. Unlike newer homes with sealed systems, older brick homes often have deteriorated masonry, missing liners, or blocked flues that let CO seep into living spaces. Symptoms mimic the flu: dizziness, nausea, and headaches. The key difference? CO has no smell or color. Golden’s high elevation and dry climate worsen the risk because older brick chimneys dry out faster, cracking mortar and accelerating wear. If your home has a brick fireplace built before the 1980s, it’s especially vulnerable. The Chimney Safety Institute of America (CSIA) warns that 80% of chimney-related CO leaks start with a cracked liner or improperly sealed masonry, both common in Denver’s older neighborhoods like Golden’s downtown historic district.
How to spot carbon monoxide risks in your Golden chimney
A chimney sweep in Golden will check for these three red flags in older brick homes: 1. Cracked or missing liners: If your chimney has no stainless-steel liner (common in pre-1990s homes), the brickwork itself acts as the flue, but mortar joints crack over time. Look for rust around the fireplace damper or soot stains on the ceiling near the chimney. The EPA’s Burn Wise program notes that unlined brick chimneys lose 30% more heat and are 5x more likely to leak CO. 2. Damaged masonry: Check for crumbling brick, loose mortar, or gaps wider than a pencil. In Golden’s dry climate, mortar dries out faster, creating gaps where CO escapes. Run your hand along the chimney exterior, if you feel rough edges or hollow spots, the masonry is compromised. 3. Blocked or rusted dampers: A rusted damper (common in older homes) can’t seal properly, letting CO into the house. If your damper sticks or looks pitted, it’s time for a replacement. The National Fire Protection Association (NFPA) states that a stuck damper is the #1 cause of CO leaks in brick fireplaces.
For Golden homeowners, the first step is a visual inspection from a licensed chimney sweep. They’ll use a camera to check for hidden cracks or creosote buildup that traps CO. If your home is near Clear Creek or the foothills, moisture from humidity changes can also weaken brickwork, another CO risk. Book a Golden chimney inspection today to rule out leaks before winter.
The two types of chimney repairs that stop CO leaks
If your Golden chimney sweep finds CO risks, you’ll need one of these fixes: 1. Relining: For older brick chimneys, a stainless-steel liner (like those we install) creates a sealed flue inside the existing brickwork. This costs $1,200–$3,500 in Denver, depending on chimney height and liner type. The CSIA recommends relining every 15–20 years for brick chimneys, or sooner if you see rust or cracks. Relining also cuts fire risks, 90% of chimney fires start in unlined or damaged flues the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)). 2. Masonry repair: Cracked brick or mortar is sealed with high-temperature mortar and repointed. For Golden’s historic homes, this preserves the original brickwork while fixing CO gaps. Labor costs $500–$1,500 depending on chimney height and damage. If the brick itself is crumbling, partial rebricking (replacing damaged sections) may be needed, this runs $2,000–$5,000 for a full chimney.
Pro tip for Golden homeowners: If your chimney is over 50 years old, combine relining with masonry repair. Older brickwork hides internal damage until it’s too late. Ask about our Golden chimney repair packages, we often bundle relining and repointing for a discount.
When to call a chimney sweep in Golden vs. waiting
Don’t wait for symptoms to act. Schedule a chimney sweep in Golden if you see: - Yellow or flickering flames: A sign of poor airflow or CO buildup. - Soot on walls or ceilings: Means gases aren’t venting properly. - Condensation inside the chimney: Indicates a cracked liner or blocked flue. - Animals nesting in the chimney: Squirrels or birds block airflow and create CO traps.
Golden’s dry winters make CO risks worse, cold air contracts, increasing pressure differences that push gases into your home. The CSIA advises inspecting chimneys before the first cold snap, especially in older homes. If you’re unsure, a Level 2 inspection (which includes a camera scan) costs $150–$300 in Denver and catches hidden issues. See our Golden inspection pricing for transparent quotes.
How to prevent CO leaks between chimney sweeps
Older brick chimneys need year-round care. Here’s how Golden homeowners can reduce CO risks: 1. Burn only seasoned wood: Wet or resinous wood creates more creosote, clogging flues and trapping CO. The EPA’s Burn Wise program recommends dry wood with 20% moisture or less, test it with a moisture meter or knock two pieces together (seasoned wood sounds hollow). 2. Use the damper: Always close it when the fireplace isn’t in use to prevent downdrafts that pull CO into the house. 3. Install CO detectors: Place them 10 feet from the fireplace and test monthly. Battery-powered models are best, hardwired detectors fail in power outages, a common issue during Denver’s winter storms. 4. Check for backdrafts: Light a match near the fireplace opening, if the flame flickers inward, your chimney isn’t drawing properly. This is a CO warning sign.
For Golden’s historic homes, annual chimney sweeps are non-negotiable. Creosote buildup (common in older brick chimneys) restricts airflow, increasing CO risks. Learn how creosote forms in Denver chimneys and why professional cleaning removes it safely.
What to do if you suspect CO poisoning
If you or someone in your Golden home feels sick after using the fireplace: 1. Evacuate immediately: Go outside and call 911. 2. Danger remains: Carbon monoxide can stay in the air even after you shut off the fire. 3. Call a chimney sweep: A professional will inspect for leaks, cracks, or blockages. In Denver, emergency chimney inspections cost $200–$400, higher than routine checks due to urgency. 4. Get medical help: CO poisoning requires treatment, even if symptoms seem mild.
After the crisis, replace old chimney components. A rusted damper or cracked liner won’t fix itself. Our Golden team offers emergency inspections, we’ve seen cases where homeowners ignored symptoms until it was too late. Don’t wait.

Frequently Asked Questions
How much does it cost to fix a CO-leaking chimney in Golden?
Fixing a CO-leaking chimney in Golden costs $500–$3,500, depending on the repair. A cracked liner runs $1,200–$3,500, while masonry repointing is $500–$1,500. If your chimney is over 50 years old, bundle relining and repair for savings. Get a Golden chimney repair quote to avoid overpaying.
Can I use my fireplace after a chimney sweep if CO risks are found?
No. If your chimney sweep finds CO risks like a cracked liner or blocked flue, do not use the fireplace until repairs are done. CO can build up even with minor damage. Schedule fixes immediately, our Golden team does same-day inspections for urgent cases.
Why do older brick chimneys in Golden leak CO more than newer ones?
Golden’s older brick chimneys lack modern liners, so gaps in mortar or brick let CO seep in. Dry climate and high elevation also speed up wear. The CSIA found that pre-1980s brick chimneys are 4x more likely to leak CO than lined systems. Learn how to upgrade your Golden chimney to stop leaks.
How often should I have my Golden chimney checked for CO risks?
Golden homeowners should have their chimneys inspected annually before winter, with a Level 2 inspection every 2–3 years if the chimney is over 30 years old. The NFPA recommends this for older brick homes. Book a Golden chimney inspection to stay ahead of CO risks.
