A chimney sweep in Glenolden or Sharon Hill isn’t just about removing soot, it’s about catching hidden damage in your brickwork or liner before it becomes a fire risk. If you’ve got an older home with a masonry chimney, ignore these signs at your own peril: creosote buildup, cracked mortar joints, or a musty smell from the flue. Swarthmore’s humid summers and old brick homes make these problems worse. Get a professional inspection before winter hits, it could save your home.
A chimney inspection is a detailed check of your flue, liner, and masonry for cracks, blockages, or structural damage, think of it as an X-ray for your chimney’s health.
In Glenolden and Sharon Hill, where many homes date back to the early 1900s, chimneys aren’t just fireplaces, they’re part of the house’s original brickwork. That means mortar joints weaken over time, especially with Swarthmore’s damp winters and hot summers. A chimney sweep isn’t just about sweeping soot; it’s about spotting early signs of failure in your masonry or liner before they turn into costly repairs, or worse, a chimney fire. The Chimney Safety Institute of America the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) recommends an annual inspection for homes with masonry chimneys, and that’s non-negotiable if your home’s chimney is older than 30 years. We’ve seen Glenolden’s brick chimneys develop hairline cracks near the roofline after just one hard freeze, and Sharon Hill’s older homes often have liners that weren’t installed to modern standards. If your chimney’s been neglected, a sweep could reveal problems you’d never notice yourself, like a liner pulling away from the brick or mortar crumbling beyond repair. Book a chimney inspection in Glenolden or Sharon Hill before your next fire season to avoid surprises.
Creosote isn’t just black gunk, it’s a flammable tar that builds up in flues and can ignite with shocking speed, especially in older brick chimneys.
If you’ve ever seen that glossy, tar-like residue on your chimney walls, that’s Stage 2 creosote, the most dangerous kind. It hardens like varnish and can catch fire at temperatures as low as 1,100°F, well below what a typical wood fire reaches. In Swarthmore’s older homes, where chimneys often lack modern liners, creosote clings to rough brick surfaces and builds up faster. We’ve pulled out chunks of it from Glenolden chimneys that looked clean from the outside but were packed solid inside. The EPA’s Burn Wise program the EPA's Burn Wise program warns that creosote is the leading cause of chimney fires, and it’s especially risky in homes with unlined masonry chimneys. If your chimney’s been used regularly and you haven’t swept it in over a year, assume creosote is present, even if you don’t see it. A chimney sweep in Sharon Hill will remove it safely, but if it’s thick enough, you might need a professional to chip it out with tools, not just brushes. Learn how often you should sweep, it’s not just once a year for older brick homes.
Cracked mortar joints in your chimney aren’t just cosmetic, they let water seep in, erode brick, and create pathways for smoke to escape into your attic.
Swarthmore’s brick chimneys take a beating from our climate: freezing winters expand water in the mortar, and summer heat dries it out, causing cracks over time. In Glenolden, we’ve seen chimneys with mortar joints so deteriorated that rainwater pools inside the flue, rusting out metal components and weakening the brick. If you notice white, powdery residue around your chimney’s base or dark streaks running down the brick, that’s efflorescence, a sure sign moisture is migrating through cracked mortar. Worse, those cracks can let smoke bypass your flue entirely, filling your attic with soot and creating a fire hazard. A chimney sweep will check for active leaks, but if the damage is severe, you’ll need a masonry repair specialist to repoint the joints before winter. See how to spot water damage in your chimney, it’s not always obvious until it’s too late.
A musty or smoky smell coming from your fireplace isn’t normal, it means your chimney isn’t drawing properly, often due to blockages or structural issues.
If your fireplace smells like damp wood or smoke lingers in the room long after you’ve banked the fire, your chimney’s not venting correctly. In Sharon Hill, we’ve traced this to everything from bird nests (yes, really, pigeons love Glenolden’s chimneys) to collapsed liners in older homes. A blocked flue forces smoke and harmful gases back into your home, and in extreme cases, it can lead to carbon monoxide poisoning. The National Fire Protection Association the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) warns that improper draft is a top cause of chimney-related injuries. If you’ve had your chimney swept recently but the smell persists, the issue might be structural, a sagging liner, a cracked crown, or even a damaged damper. Get a professional to diagnose the problem before you light another fire. In Swarthmore’s older homes, these issues often start small and worsen quickly if ignored.
White or black stains on your ceiling or walls near the fireplace are a clear sign your chimney isn’t sealing properly, or worse, has a crack.
Those mysterious stains aren’t just from soot, they’re evidence your chimney’s failing to contain smoke and combustion byproducts. In Glenolden, we’ve seen ceilings blackened by years of undetected leaks, and in Sharon Hill, homeowners have found soot deposits on walls across the room from the fireplace. This usually means your chimney’s liner is damaged, your crown is missing, or your flashing has failed. If left unchecked, the soot can stain drywall permanently and create a fire risk if it accumulates on wooden beams. The good news? A chimney sweep will spot these issues during an inspection, but the fix might require a liner replacement or masonry repair. See what to do if you notice these stains, don’t wait until they spread.
Your chimney’s crown (the top cap) is the first line of defense against water damage, and if it’s missing or cracked, your brickwork is at risk.
Swarthmore’s frequent rain and snow mean your chimney’s crown takes a beating. If it’s cracked, missing, or sloped incorrectly, water seeps into the flue, rusts out metal components, and erodes the brick over time. We’ve seen Glenolden chimneys with crowns so deteriorated that they’ve allowed water to pool inside the flue, leading to mold growth and structural weakness. A damaged crown can also let debris fall into your chimney, creating blockages. If your crown looks like it’s been hit by hail or is crumbling, it needs replacing, before winter turns that crack into a full-blown leak. Learn how to check your crown for damage, it’s a quick visual inspection that could save you thousands in repairs.
A chimney sweep in Glenolden or Sharon Hill isn’t just about cleaning, it’s about catching problems before they become emergencies, especially in older brick homes.
Too many homeowners wait until they see flames shooting out of their chimney to call a chimney sweep. By then, it’s often too late, the damage is done, and repairs can cost thousands. In Swarthmore’s older neighborhoods, where chimneys are part of the home’s original construction, neglect leads to cascading failures: a small crack in the liner lets water in, which rusts out the damper, which then fails to seal, allowing smoke to escape. The result? A chimney that’s no longer safe to use. The key is proactive maintenance. We recommend scheduling a chimney sweep in Glenolden or Sharon Hill at least twice a year if you use your fireplace regularly, once before winter and once after. For homes with unlined masonry chimneys, an annual inspection is a must. See our seasonal chimney maintenance schedule for Swarthmore, it’s tailored to our climate and older brick homes.

Frequently Asked Questions
My chimney in Glenolden looks fine from the outside, but I keep smelling smoke in my house even after a sweep. What’s wrong?
That smell means your chimney isn’t venting properly, often due to a damaged liner, a blocked flue, or a failed damper. In older brick homes like those in Glenolden, liners can sag or crack over time, creating gaps that let smoke bypass the flue. If your chimney was swept recently but the smell persists, the issue might be structural, a sagging liner or a cracked crown. Contact us for a diagnostic inspection, we’ll use a camera to check your flue and find the root cause before it becomes a fire hazard.
Why does my Sharon Hill chimney need a liner if it’s been working for years? Isn’t the brick enough?
Brick alone isn’t enough protection for a chimney, especially in Swarthmore’s climate. Older brick chimneys lack the insulation and durability of modern liners, which shield against heat damage, creosote buildup, and moisture. Without a liner, your brick erodes faster, and the flue can become a fire risk. If your chimney’s over 30 years old or you’ve noticed cracks in the mortar, a liner could extend its life and improve safety. Learn about liner options for older brick chimneys, we specialize in retrofitting them without major demolition.
I found white powder near the base of my chimney in Swarthmore. Is that just dirt, or should I be worried?
That white powder is efflorescence, a sign of water damage seeping through cracked mortar or brick. In Swarthmore’s humid summers and freeze-thaw cycles, it’s a red flag that your chimney’s integrity is compromised. If ignored, it can lead to structural weakness and even chimney collapse. Get a professional to inspect your mortar joints, we’ll determine if repointing or masonry repair is needed before winter worsens the damage.
How much does a chimney sweep cost in Glenolden, and why do older brick homes cost more?
A standard chimney sweep in Glenolden or Sharon Hill typically ranges from $120 to $250, depending on the chimney’s height, condition, and whether it’s lined. Older brick chimneys often cost more because they require extra time to inspect for hidden damage, like cracked mortar or deteriorated liners. If your chimney needs repairs beyond sweeping, costs can rise quickly, repointing mortar might add $500 to $1,500, while a new liner can cost $1,500 to $3,000.
