If your chimney is due for a sweep and you’ve ignored it for more than a year, or if you’ve never had one, your home is at risk. Sharon Hill and Glenolden homes, especially older brick row houses and ranch-style homes with wood-burning fireplaces, see faster creosote buildup due to Philadelphia’s humid summers and damp winters. A professional chimney sweep isn’t just about removing soot; it’s about spotting cracks, blockages, or deteriorating flue liners that let carbon monoxide into your home. The Chimney Safety Institute of America recommends an annual inspection and sweep for wood-burning fireplaces, but many homeowners skip it until they see smoke in their living room. Don’t wait for a warning sign, schedule a sweep before your next fire season.
1. A chimney inspection is NOT the same as a sweep, and skipping either puts your home at risk.
Many homeowners in Sharon Hill and Glenolden confuse a chimney inspection with a sweep, assuming a quick visual check is enough. But an inspection (Level 1 or 2, per NFPA 211) looks for structural damage, while a sweep removes flammable creosote and soot. Here’s the difference: An inspection can miss hidden creosote deep in the flue, and a sweep alone won’t catch a cracked chimney crown or deteriorated liner, both of which let carbon monoxide into your home. Rosewood Flame’s crews perform both during every visit, using video cameras to inspect flues that can’t be seen from the top. In Philadelphia’s older homes, where brick chimneys often lack modern liners, this dual approach catches problems before they become emergencies. For example, a Glenolden homeowner last winter nearly missed a cracked flue tile until our crew spotted it during a Level 2 inspection after a sweep revealed excessive creosote buildup. The tile was replaced before carbon monoxide levels became dangerous. the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) recommends Level 2 inspections for homes with any signs of damage or before selling a property, so if you’re listing your Sharon Hill home, don’t skip this step. There is more in the full list of services.
2. You’re burning wood in Philadelphia’s humidity, and that’s creating a tinderbox in your flue.
Philadelphia’s summers are hot and humid, and our winters bring damp air that condenses inside chimneys, speeding up creosote formation. Creosote isn’t just soot; it’s a sticky, tar-like substance that builds up in layers. The first stage (foamy) looks harmless, but the second (tar-like) stage is highly flammable and can ignite with a single spark. Many homeowners in Glenolden and Sharon Hill assume their gas fireplaces don’t need sweeping, but even gas units require annual inspections to check for corrosion or blockages from bird nests or debris. Wood-burning fireplaces in these areas see faster buildup because homeowners often burn unseasoned wood or low-quality logs to save money, a mistake that clogs the flue with unburned particles. The EPA’s Burn Wise program the EPA's Burn Wise program advises burning only seasoned hardwood to reduce creosote, but even then, a professional sweep is needed annually. Last fall, a Sharon Hill family’s fireplace nearly caused a chimney fire because they’d been burning pine scraps from a local hardware store. Our crew removed a thick layer of stage 2 creosote and reinforced the damper to prevent future blockages. For details, see book a visit or ask a question page.
3. Your CO detector goes off after lighting a fire, even if you don’t smell gas.
Carbon monoxide (CO) is odorless and deadly, yet many Philadelphia homeowners dismiss a CO alarm as a false positive. If your alarm sounds after lighting a fire, your chimney is leaking CO into your home, likely due to a cracked liner, blocked flue, or improper draft. Older homes in Glenolden and Sharon Hill, especially those with unlined brick chimneys, are prone to this issue because the mortar between bricks can deteriorate over time. A blocked flue (from creosote, debris, or animal nests) forces CO back into the living space. Rosewood Flame’s crews use CO detectors during every sweep to test for leaks, and we’ll seal cracks or reline the flue if needed. Last winter, an Aldan homeowner’s CO alarm went off after burning a single log; our inspection revealed a spider nest blocking the flue. Once cleared, the draft improved, and the alarm stopped sounding. If your CO detector triggers after lighting a fire, don’t ignore it, schedule a Level 2 inspection immediately. USA.gov warns that CO poisoning is the leading cause of accidental poisoning deaths in the U.S., and chimneys are a common source. For the specifics, see our crew and certifications.
4. Smoke is pouring into your living room instead of up the chimney, this isn’t normal ‘smoke smell.’
A little smoke smell when lighting a fire is normal, but if you see visible smoke in your room, your chimney has a blockage or poor draft. Common causes in Sharon Hill and Glenolden include: creosote clogging the flue, a damaged chimney cap letting rainwater pool inside, or a collapsed flue liner. Many homeowners try to ‘fix’ this by opening windows or adjusting the damper, but these are temporary solutions. A professional sweep will clear the blockage, and our crews often find that the real issue is a deteriorated liner or a chimney crown that needs repointing. For example, a Glenolden homeowner last December thought their smoke issue was just a draft problem, until we discovered a collapsed clay liner that had been restricting airflow for years. The fix required relining the flue, but catching it early prevented a chimney fire. If smoke is backing up, don’t keep burning, extinguish the fire and call a chimney sweep before creosote ignites. For details, see our areas we serve.
5. Your chimney cap is missing, rusted, or letting water inside. Philadelphia’s rain and snow make this a ticking time bomb.
A missing or damaged chimney cap is one of the fastest ways to ruin a chimney. In Philadelphia’s climate, rain and snow enter through gaps, freezing and thawing to crack the masonry. Over time, this leads to water damage, rusted flue liners, and even structural collapse. Many homeowners in Sharon Hill and Glenolden assume a chimney cap is optional, but it’s the first line of defense against debris, animals, and moisture. Rosewood Flame installs only stainless steel caps with mesh screens to prevent blockages while allowing proper draft. Last spring, a Sharon Hill homeowner’s chimney cap had blown off in a storm, and by the time they noticed, water had eroded the flue liner. Our crew replaced the cap and sealed the crown to prevent future leaks. If your cap is missing, bent, or rusted through, replace it before winter. Philadelphia’s freeze-thaw cycles will worsen the damage if you wait. the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) recommends inspecting and maintaining chimney caps annually. For details, see Chimney Sweep in Darby, PA page.
6. You hear popping or crackling sounds that aren’t just the fire burning, this could mean creosote is igniting.
A wood fire should crackle from burning logs, but if you hear loud popping or a rumbling sound from the chimney, creosote is likely igniting inside the flue. This is the first stage of a chimney fire, and it’s often mistaken for normal burning. The NFPA reports that chimney fires double in frequency during cold snaps when homeowners burn more wood, and Philadelphia’s sudden temperature drops create ideal conditions. Many homeowners in Glenolden and Sharon Hill have woken to the sound of a chimney fire only to find their flue glowing red. Rosewood Flame’s crews use thermal imaging to check for heat damage after a suspected chimney fire, and we often find that the real issue is a lack of maintenance. For example, a Folcroft homeowner last November heard popping sounds and saw flames in the fireplace, our crew found a thick layer of stage 2 creosote that had nearly ignited. The fix required a full flue sweep and a new stainless steel liner to prevent future fires. If you hear unexplained popping, turn off the fire immediately and call a chimney sweep before the creosote fully ignites.
7. Your chimney sweep appointment should include these 3 steps, most competitors skip at least one.
Philadelphia’s chimney sweep industry isn’t created equal, some cut corners while others follow strict safety rules. Many crews charge for a ‘sweep’ but only perform a basic brush-out, missing critical steps like inspecting the flue for cracks or testing for CO leaks. Rosewood Flame’s process includes: 1. Video inspection of the flue to check for hidden damage or blockages (most competitors rely on visual checks). 2. Creosote removal using rotary tools for stubborn buildup (brushes alone leave residue). 3. Draft testing to ensure proper airflow and CO detector activation if leaks are found. For example, a Drexel Hill homeowner last year hired a crew that only brushed the flue and charged $120, but when their CO alarm went off weeks later, they called us. Our inspection revealed a cracked liner that the other crew missed. The correct fix required relining the flue, costing $2,500, but catching it early prevented a carbon monoxide poisoning risk. If you’re comparing quotes, ask if the sweep includes a video inspection and CO testing. Many ‘discount’ sweeps cut corners here, and the savings aren’t worth the risk. the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) certifies that only Level 2 inspections (with video) can fully assess chimney safety.

Frequently Asked Questions
How much does a chimney sweep cost in Sharon Hill or Glenolden, and is it worth paying extra for a Level 2 inspection?
A basic chimney sweep in Sharon Hill or Glenolden typically costs between $150 and $250, depending on the chimney height and creosote buildup. Adding a Level 2 inspection (which includes video scanning) adds $100–$200. While this seems expensive, the cost of repairing a chimney fire or CO leak, like relining a flue or replacing a damaged liner, can run $3,000 to $10,000. For example, a Glenolden homeowner saved $5,000 last winter by catching a cracked liner during an inspection before it caused a fire. If your chimney is older than 20 years or you’ve never had an inspection, the extra cost is worth it. Rosewood Flame offers free estimates and explains all findings upfront, no surprises. See our pricing guide for more details.
Can I wait until winter to get my chimney swept, or does Philadelphia’s summer humidity make a difference?
No, you shouldn’t wait until winter. Philadelphia’s summer humidity accelerates creosote buildup, and a sweep in late summer or early fall ensures your chimney is ready for the first cold snap. Many homeowners assume they have time, but creosote forms faster than they realize, especially if you’ve been burning wood regularly. The Chimney Safety Institute of America recommends sweeping at least once a year for wood-burning fireplaces, and some insurance companies in Pennsylvania require proof of annual maintenance to avoid claim denials. If you haven’t swept since last winter, schedule one now before the next heating season. Learn more about seasonal chimney care.
I’ve heard that DIY chimney cleaning can save money, is it safe in Philadelphia’s older homes?
DIY chimney cleaning is risky, especially in Philadelphia’s older homes where brick chimneys often lack modern liners. Without proper tools or training, you can push creosote deeper into the flue, damage the masonry, or miss hidden cracks that let carbon monoxide in. The NFPA warns that improper cleaning can void your homeowner’s insurance coverage if a chimney fire occurs. Many DIY kits on the market are ineffective for heavy buildup and can leave residue that worsens draft issues. For example, a Sharon Hill homeowner tried a $50 brush kit last year and ended up with a clogged flue that required a professional to fix. If you’re set on saving money, focus on burning only seasoned hardwood and having a professional sweep annually. See what chimney work you can safely DIY, and what to avoid.
My neighbor’s chimney sweep charged me $100 less, why does Rosewood Flame cost more?
Many ‘cheap’ chimney sweeps cut corners by skipping critical steps like video inspections, CO testing, or thorough creosote removal. Rosewood Flame’s pricing reflects our safety-first approach: we use rotary tools for deep cleaning, thermal imaging to check for heat damage, and video inspections to spot hidden issues. For example, a Folcroft homeowner paid $120 for a sweep elsewhere but had to call us for a $2,000 liner repair weeks later when their CO alarm went off. Our upfront cost is higher, but it prevents costly repairs down the line. We also offer warranties on our work and stand behind our inspections, something many competitors don’t. Compare DIY vs. professional sweeping costs to see why investing in a certified crew pays off.
