Fall is the best time to inspect your chimney before Maplewood’s first cold snap. You can safely check for creosote buildup, test draft strength, and spot cracks, but stop immediately if you see soot in your home or smell gas. For anything beyond basic checks, call a licensed chimney sweep like Jeremy B Chimney Company to avoid carbon monoxide risks or fire hazards.
What Safety Checks Can Maplewood Homeowners Do Themselves (With These Steps)?
Before you climb a ladder or touch your chimney, turn off the fireplace and let it cool completely. Then grab a flashlight and inspect these three critical areas from the top of the roof down: 1. Chimney cap: Look for rust, warping, or missing pieces. A damaged cap lets rain and debris in, which accelerates deterioration. If it’s loose, do not attempt to fix it yourself, a poorly secured cap can detach and cause damage or injury. 2. Masonry surface: Scan for cracks wider than 1/8 inch or crumbling bricks. Maplewood’s freeze-thaw cycles worsen these over time. If you see mortar popping out, note the location but do not chip or repair it, this can weaken the structure. 3. Firebox and smoke chamber: Shine the light inside and check for thick creosote (a black, tar-like buildup). If it’s glossy or hard like candy, it’s Level 3 creosote, a fire hazard that requires professional removal. For lighter buildup, you can vacuum it out with a chimney brush (available at hardware stores) only if you’re comfortable with the process.

How to Test Your Chimney’s Draft in Maplewood’s Fall Weather
A weak or reversed draft is a silent carbon monoxide risk. Here’s how to test it safely: 1. Burn a small scrap of newspaper near the fireplace opening to test the draft. If the flame flickers outward, your draft is weak, likely due to blockages or poor ventilation. 2. If smoke spills into the room instead of rising, your chimney may be partially blocked (by debris, animal nests, or creosote) or improperly sized for your fireplace. 3. Never burn trash, cardboard, or unseasoned wood, these create excessive creosote and clog flues faster. Maplewood’s dry fall air can also increase static electricity, making creosote stick harder to chimney walls. If the flame won’t stay lit or smoke backs up, stop using the fireplace immediately. Call Jeremy B Chimney Company for a draft test and inspection, we’ll check for blockages, cracks, or structural issues that DIY tools can’t detect. See our seasonal safety calendar for Maplewood to schedule your sweep before winter.
Warning Signs Your Chimney Needs a Professional (Stop DIY Immediately)
These red flags mean you should not use your fireplace and must call a licensed chimney sweep before attempting any repairs: - Burning smells or smoke in the house: This isn’t just ‘old wood’, it’s a sign of creosote fires or carbon monoxide leaking from cracks. Never ignore this; even a ‘quick fix’ like duct tape can trap deadly gases. - Orange or yellow flames instead of blue: Healthy fires burn blue. Orange/yellow flames mean incomplete combustion, which coats your chimney with flammable creosote and fills your home with toxic fumes. - White, powdery residue on walls or furniture: This is soot from a cracked flue liner, a direct path for carbon monoxide into your living space. DIY patching fails because flue liners must be professionally sealed to code. - Animals nesting in your chimney: Birds, squirrels, or raccoons can block your flue completely. If you hear scratching or see droppings, do not reach in, you risk injury or dislodging a nest into your home. Learn how to spot these signs early and call us for a safe removal and inspection.
What Chimney Tasks Should Maplewood Homeowners Avoid DIYing (And When to Call Us)
Some chimney issues are code violations or fire hazards if attempted by untrained hands. Avoid these four mistakes: 1. Repairing a cracked flue liner: These are made of ceramic, cast-in-place, or stainless steel, materials that require professional welding or sealing. A DIY ‘fix’ can collapse under heat or leak carbon monoxide. 2. Removing Level 3 creosote: This hard, tar-like buildup requires high-pressure water jetting or mechanical brushing, tools that can damage your chimney if misused. Scraping it with a knife or wire brush spreads flammable dust into your home. 3. Installing a new chimney cap: If yours is damaged, measure twice, a cap that’s too small traps moisture, and one that’s too large reduces draft. Improper installation can void manufacturer warranties and create gaps for sparks. 4. Ignoring local codes: Maplewood follows Minnesota State Fire Code for chimney clearances and materials. A DIY repair that doesn’t meet these standards can fail inspections or invalidate your homeowner’s insurance in case of a fire. Check our pricing guide to see how professional inspections save money long-term, especially in older homes where hidden damage is common.
How do I know when my chimney needs professional repairs in the Maplewood area?
If you’ve spotted any of the warning signs above, or if you’re unsure about what you’ve found, call us before you use your fireplace again. Here’s when to reach out: - Before your first fall burn: Schedule a pre-winter inspection to catch issues before they become emergencies. Our CSIA-certified sweeps use video inspections to spot hidden problems (like cracked liners) that a visual check misses. - After a power outage or strong winds: Storms can displace chimney caps or damage masonry. Even if it looks fine, test your draft, if it’s weak, we’ll diagnose the cause. - If your chimney is over 20 years old: Older chimneys develop hidden corrosion or structural weaknesses. We’ll check for efflorescence (white powder) or spalling bricks, signs of moisture damage that DIY repairs can’t fix. - For gas fireplace servicing: If you have a gas fireplace, never attempt to clean the vent or adjust the burner yourself. Carbon monoxide leaks from gas systems are silent and deadly, our certified technicians can inspect the entire combustion system safely.

Frequently Asked Questions
My chimney looks fine, but my Maplewood fireplace smells like gas even when it’s off. What should I do?
This is carbon monoxide leaking from a cracked flue liner or improperly sealed gas connection. Do not use the fireplace and ventilate the room while you wait for a professional. Gas smells can also come from a clogged vent or failed pilot light, both require a licensed technician to fix safely. Call Jeremy B Chimney Company immediately for an emergency inspection; we serve Maplewood and nearby areas like Vadnais Heights and Oakdale.
I found a small crack in my chimney’s mortar near the roof. Can I fix it myself with chimney cement?
No. DIY mortar repairs often fail because they don’t account for Maplewood’s freeze-thaw cycles. A small crack can expand into a structural weakness over winter. Instead, note the location and call us for a professional repointing. We’ll use heat-resistant mortar and waterproof sealants to prevent future damage. See our relining and repair guide for why this is safer than patching.
Why does my Maplewood fireplace smoke more on humid fall days, even when the draft seems fine?
Humidity reduces airflow in your chimney, making it harder for smoke to escape. This isn’t always dangerous, but if smoke spills into the room, your chimney may be undersized or blocked by creosote. Never force the issue by burning hotter, this increases creosote buildup. Instead, test your draft and call us for a chimney sizing evaluation or sweep. Learn how often you should sweep to avoid this problem next fall.
