A chimney that smells like gas in Lakewood almost always means a leak in your gas line, venting system, or a cracked flue. Never light your fireplace or stove until you’ve tested for carbon monoxide (CO) with a detector. If the smell persists after turning off gas appliances, call a licensed chimney sweep immediately, this is a fire and health hazard. In Lakewood’s dry climate, even minor leaks can worsen over time, so don’t wait for symptoms like headaches or nausea to appear.
1. A chimney inspection is a thorough check of your flue, liner, damper, and connections for cracks, corrosion, or blockages, required before lighting any fireplace in Lakewood after repairs or if you suspect gas leaks.
Lakewood’s older homes, especially those near South Dakota Creek or in the foothills, often have masonry chimneys built with mortar that weakens over decades. When mortar cracks or deteriorates, it can expose gas lines or allow natural gas to seep into the flue. A Level 2 chimney inspection (where we probe the flue with a camera) is the only way to confirm if your chimney’s liner is compromised. The Chimney Safety Institute of America (CSIA) recommends this type of inspection if you’ve ever noticed a gas odor, especially after a chimney sweep or repair. In Lakewood, where winter winds can exacerbate small cracks, a gas smell after a storm is a red flag, don’t ignore it. Schedule a Level 2 inspection if you’ve had recent work done or suspect hidden damage.
2. Your gas line connection might be leaking, here’s how to test it safely (without risking an explosion)
If your chimney smells like gas but your fireplace isn’t in use, the leak could be coming from the gas line connection where it meets your furnace, water heater, or stove. Lakewood’s older neighborhoods, like those near the Belmar Shopping Center, often have outdated piping that corrodes over time. Here’s how to test it safely: 1. Turn off the gas supply at the meter (located outside your home). 2. Use a soapy water solution (not lighter fluid!) to spray all visible gas line connections, including the one near your chimney. 3. If bubbles form, you have a leak, do not turn the gas back on. Call a licensed plumber immediately. 4. If no bubbles appear but the smell persists, the leak is likely inside the chimney or venting system, and you’ll need a chimney sweep Lakewood to inspect the flue. Never attempt to light a pilot light or use gas appliances if you suspect a leak. The U.S. Environmental Protection Agency warns that even small leaks can lead to carbon monoxide buildup, which is odorless and deadly. Contact us for an emergency inspection if you’re unsure.
3. Creosote buildup can trap gas odors, and hiding a bigger problem (like a cracked flue)
Creosote, the sticky tar-like substance left behind from burning wood, doesn’t just clog your chimney, it can absorb and trap gas odors, making it seem like your chimney smells like gas when the real issue is something else. In Lakewood, where many homeowners switch between wood and gas fireplaces, creosote buildup is a year-round concern. Here’s why it matters: - Stage 1 creosote (sooty) is less dangerous but can still mask leaks. - Stage 2 (tar-like) or Stage 3 (hard, glassy) creosote indicates poor ventilation and increases fire risk. If your chimney smells like gas and you’ve been burning wood, a chimney sweep Lakewood should remove creosote while checking for cracks or gaps where gas could seep in. The National Fire Protection Association (NFPA) states that creosote is a leading cause of chimney fires, and trapped gas odors can delay detection of a real leak. Book a sweep before winter. Lakewood’s dry air accelerates creosote buildup, especially in unlined masonry chimneys.
4. Should I be worried if the smell only happens when I light the fireplace?
If the gas smell appears only when you light your fireplace or stove, the issue is likely one of three things: 1. A cracked or corroded flue liner, common in Lakewood’s older brick chimneys, where moisture from snowmelt or humidity can weaken mortar joints. 2. Improper venting, if your gas appliance isn’t sized correctly for the chimney, it can force gas back up the flue. 3. A blocked chimney cap, debris or animal nests can trap gas odors and prevent proper ventilation. What to do next: - Turn off the appliance immediately and open windows to ventilate. - Check your chimney cap, if it’s missing or damaged, gas fumes can’t escape properly. - Call a chimney sweep Lakewood to inspect the flue with a camera. A Level 1 inspection (visual check) might reveal obvious issues, but a Level 2 (with tools) is needed for hidden cracks. The CSIA recommends this if you suspect venting problems. Learn about inspection levels to choose the right service for your home.
5. Is it worth fixing a small gas smell now, or should I wait until winter?
Waiting to fix a gas smell in your chimney is never worth the risk, especially in Lakewood, where winter winds can worsen leaks and carbon monoxide (CO) buildup. Here’s why acting now saves money and lives: - CO poisoning is silent. You won’t smell it if the gas line is fully compromised, but symptoms like headaches, dizziness, or nausea appear too late. - Mortar cracks expand in cold weather. Lakewood’s temperature swings (from 80°F summers to sub-zero winters) cause masonry to shift, turning small leaks into major hazards. - Insurance may not cover gas-related fires. If a leak ignites, your homeowners’ policy might deny the claim if you ignored warning signs. Cost comparison: | Issue | DIY Fix Cost | Pro Fix Cost (Lakewood) | Emergency Repair Cost | |---------------------|--------------------|-------------------------|----------------------| | Minor gas line leak | $50–$150 (parts) | $200–$400 (plumber) | $1,000+ (if ignited) | | Cracked flue liner | Not recommended | $300–$800 (relining) | $2,000+ (rebuild) | | Creosote + gas odor | $0 (prevention) | $120–$250 (sweep) | $500+ (fire damage) | Bottom line: A chimney sweep Lakewood costs far less than an emergency repair.

What’s the point of sweeping if you only light up for holiday gatherings in your South Lakewood home?
Even if you use your fireplace once a month, a chimney sweep is non-negotiable in Lakewood’s climate. Here’s why: - Condensation builds faster in unused chimneys. Lakewood’s humidity and temperature shifts create moisture that corrodes flue liners, even without fires. - Animal nests block vents. Squirrels and birds love Lakewood’s chimneys, and their debris can trap gas odors while restricting airflow. - Gas appliances still need venting checked. If your furnace or water heater vents through the chimney, a blocked flue can force gas back into your home. The CSIA recommends annual inspections for all chimneys, but if you’ve noticed a gas smell, schedule a sweep immediately. Our Lakewood team covers homes in Wheat Ridge and Golden too, we’ll check for leaks, creosote, and structural issues in one visit. Pro tip: If you’ve had your chimney inspected recently but still smell gas, ask about a smoke test, we’ll use specialized equipment to trace the odor’s source.
7. What’s the fastest way to stop the smell while waiting for a chimney sweep?
If you’ve confirmed it’s a gas smell (not just damp wood or a draft), do these three things immediately to reduce risk: 1. Turn off gas appliances at the meter and open all windows for 15–20 minutes to ventilate. 2. Hold off on firing up that fireplace or wood stove until a certified sweep inspects and cleans it first. 3. Install a carbon monoxide detector near sleeping areas if you don’t have one. The EPA recommends testing detectors monthly. Lakewood’s high elevation can make CO spread faster. Temporary fixes that don’t work: - Lighting a fire to “burn off” the smell (this can ignite trapped gas). - Spraying air fresheners (masks the odor but not the hazard). - DIY chimney cleaning (risky without proper tools). Instead, call a licensed chimney sweep Lakewood, we’ll identify the source and repair it safely. Emergency service is available for same-day inspections if you’re concerned about CO exposure. Remember: In Lakewood, where winter chimney fires spike in December, time is critical.

Frequently Asked Questions
Should I call a plumber or a chimney sweep first if my Lakewood chimney smells like gas?
Call a chimney sweep Lakewood first if the smell comes from the chimney itself or when you use the fireplace. If the odor is strongest near gas appliances (like the furnace or stove) and you see bubbles in soapy water, a plumber handles the gas line. For chimney-related gas smells, we’ll inspect the flue, liner, and connections, never light the fireplace until we clear it. Our team can coordinate with plumbers if needed.
Is it worth paying for a chimney inspection if I’ve never had a problem before?
Yes, especially in Lakewood, where 30% of chimney fires start from undetected leaks or creosote buildup. A Level 1 inspection (visual check) costs $100–$150 but can catch early signs of gas leaks, cracks, or animal nests before they become hazards. The CSIA recommends annual inspections for safety, and Lakewood’s dry winters make creosote and corrosion worse over time. Schedule a preventive inspection to avoid costly repairs later.
Do I need a new chimney liner if my Lakewood chimney smells like gas?
Not always, a chimney sweep Lakewood will first check for cracks or gaps in your existing liner. If it’s damaged, relining (not replacement) is often the fix, costing $300–$800. However, if the smell comes from a separated gas line connection near the chimney, a plumber will handle that separately. Never assume it’s the liner, we use cameras to confirm the source. Ask about our diagnostic process to avoid unnecessary upgrades.
Can I use my fireplace after a chimney sweep if the gas smell is gone?
Only if the sweep confirms no leaks, cracks, or blockages in the flue or venting system. Even if the smell disappears, we’ll test for proper draft and CO levels before giving the okay. In Lakewood, where winter winds can reopen small cracks, we recommend a follow-up inspection after your first fire of the season. We provide a safety certificate after every sweep, ask for it before lighting up.
