Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Fast, Reliable Chimney Inspection Across Collingdale
A chimney inspection in Collingdale typically costs between $189 and $549 depending on the level, with most Level 1 visual checks running $189 – $279 and a Level 2 camera inspection (the kind nearly every Collingdale twin and row home needs) falling between $349 and $549. We’re Alcott Chimney Sweep, and we’ve worked these dense Delaware County blocks long enough to know that most chimneys here were built before 1945 and have a story to tell. If yours hasn’t been scoped in years, or you’re buying a home on Chester Pike or Clifton Avenue, call (336) 863-3889 and we’ll get you on the schedule with a written price before anyone climbs a ladder.
Why Alcott Chimney Sweep Is Collingdale’s Preferred Chimney Inspection Company
Collingdale homeowners call us because we show our work. Ruben Castellano built Alcott Chimney Sweep on a simple rule: no repair gets recommended unless the homeowner can see it on camera with their own eyes. That matters in a borough full of century-old brick twins where ambiguous chimney issues routinely become expensive upselling opportunities for less careful companies. We won’t tell you a liner is shot because it’s old. We’ll show you the crack, explain what it means for the flue next door, and give you a written price before anything starts.
Every technician who rolls into Collingdale has passed a background check and identity verification under the Threshold Standard. You’ll know the technician’s name and see their photo before we arrive, and they’ll show a photo ID badge at the door. No exceptions. That’s not an upgrade offer. It’s how we’ve operated since 2002.
When a Collingdale homeowner calls about a chimney that smells like smoke at odd hours, a live person answers. Not a voicemail. Not a callback queue. Twenty-four hours a day, seven days a week. And every repair we complete here carries a written guarantee. If it fails within the coverage period, the second visit is free. That’s our 365-Day Done Right Promise, and it applies to every job we finish in this borough.
Fireplace Inspection in Collingdale
Fireplace inspection in Collingdale is not a quick glance up the flue. It’s an evaluation of the firebox, damper, smoke chamber, and the liner behind them. Most homes here still run their original masonry, so what we’re checking is whether the system you light fires in is still structurally coherent after 80 to 110 years of coal smoke, gas conversion, and Southeastern Pennsylvania weather. In Collingdale, a standalone fireplace inspection runs $189 – $279 when it’s a Level 1 check, but if we’re in a century-old twin where the stack is shared or signs of moisture show up, we’ll recommend stepping up to a Level 2 camera scope.
Visible Firebox and Damper Review
We examine the firebox bricks for spalling (the face of the brick popping off under heat and moisture), check the damper’s operation and seal, and look for the first signs of acidic creosote eating at the smoke shelf. Collingdale fireplaces that only get used a few times each winter often hide first-degree creosote that’s gone acidic during humid summers. We document all of it with photos.
When to Time Your Inspection
The best time to inspect a fireplace in Collingdale is before you light it for the season. Late September through October is when we see the most calls, because the first fire of fall is when hidden problems become visible. But if you’re buying or selling a row home in this market, don’t wait for winter. Real estate transactions in the borough now routinely require a Level 2 inspection, and we handle those regularly.
Chimney Inspection Services in Collingdale
Chimney inspection services in Collingdale cover more than fireplaces. Most of the chimneys we scope here vent gas furnaces and water heaters, and that’s where the real safety issues live. A Level 1 inspection is a visual check of accessible portions of the flue, and it runs $189 – $279 in Collingdale. A Level 2 adds a scan with a camera system, which lets us see the entire lining of the flue from top to bottom, and in this borough it costs $349 – $549. That’s the price range for scoping one flue. If you live in a twin, both flues need to be looked at, and we’ll price that before we start so there’s no surprise.
Camera Scoping of Full Flue Length
Our Chimney Inspection team uses a push-camera system that shows us every inch of the flue on a screen we can hold up for you. You’ll see exactly what we see. That’s how we discovered a cracked wythe on a twin along Chester Pike’s residential blocks. Two side-by-side flues, one shared brick column, and the thin divider between them had spalled open, letting flue gas from the neighboring unit’s furnace bleed toward the other side. We documented it on camera for both homeowners, then HeatShield-resurfaced the damaged clay tile and reset the chimney crown while the feed stayed live. Neither owner had ever been told their stack was shared.

Real Estate and Pre-Purchase Inspections
Collingdale’s housing stock moves steadily because the location is solid and the prices are reasonable relative to Philadelphia. But nearly every transaction on a 1910s – 1940s brick twin or row should include a Level 2 inspection, because the seller rarely knows what’s inside the flue any better than the buyer does. We provide a written, photo-supported report that both sides can use at the table. No vague claims, no scare tactics. Just documented facts.

Trusted Brands We Service in Collingdale
When repairs do come up, we work with the materials chimney professionals actually specify: HeatShield for resurfacing clay tile liners, Gelco for water repellents and cap systems, and Olympia Chimney for accessories and components. We keep common parts accessible for Collingdale customers, which means if your inspection turns up a failed cap or a deteriorating flue crown, we can usually quote the fix and schedule it without waiting on a special order. You won’t find box-store substitutes on any job we do in this borough, because a shared-wythe twin chimney is not the place for off-brand shortcuts.
Common Chimney Inspection Problems We See in Collingdale Homes
- Cracked original clay tile liners. Homes built between 1910 and 1945 in Collingdale used clay tile that has now endured a century of freeze-thaw cycles. Southeastern Pennsylvania weather swings above and below freezing dozens of times each winter, and that’s what cracks tile from the outside while acidic condensate works from within. We scope it, document it, and show you before any repair talk starts.
- Flues oversized by coal-to-oil-to-gas conversions. Most Collingdale homes were built for coal, then converted to oil, then to natural gas. Modern gas furnaces push cooler, moister exhaust into flues sized for coal, which means poor draft, condensation, and liner corrosion on virtually every street in the borough. We see it on MacDade Boulevard, on Andrews Avenue, and on the side streets off Chester Pike, and it’s fixable once it’s measured and documented.
- Shared wythes in twin and row chimney columns. This is the Collingdale issue no one talks about until two households are involved. The brick divider between flues in a shared stack can crack, spall, and let combustion gas migrate between units. The only way to catch it is to scope both flues together. One-at-a-time inspection won’t see it.
- Acidic creosote in infrequently used fireplaces. The humid mid-Atlantic summers let first-degree creosote absorb moisture, which turns it acidic and begins eating the firebox, damper, and smoke chamber. By the time a homeowner notices poor draft or a smell, the surface damage is already underway. That’s why we check before heating season, not after.
Pricing for Chimney Inspection in Collingdale, PA
A Level 1 chimney inspection in Collingdale runs $189 – $279, and it’s the right call if you’ve used your fireplace regularly and nothing has changed. A Level 2 inspection with camera scoping is $349 – $549 for one flue, and it’s what we recommend for any home built before 1945, any brick twin or row where the stack is shared, any real estate transaction, or any system that’s been dormant. If both flues in a shared column need scoping, we quote the combined job before work begins. A Level 3 inspection, which involves accessing concealed areas, is quoted per job and only comes up when a Level 2 finds something structural that demands it. Every quote is written. Every job includes a written guarantee. Call (336) 863-3889 for a free estimate.

FAQs About Chimney Inspection in Collingdale
Yes, if both flues share a single brick column, both need to be scoped at the same time. The divider between them, called the wythe, can crack and let flue gas from one unit’s furnace move toward the other side of the wall. A one-flue-only camera inspection physically cannot show that. We’ve found this exact condition on twins along Chester Pike, and neither owner had ever heard the stack was shared. We scope both flues whenever a Collingdale twin has a shared chimney, and we document the divider for both households. Call (336) 863-3889 to set it up.
No, a Level 2 camera inspection is exactly what that liner needs. Original clay tile in Collingdale row homes is now 80 to 110 years old, and decades of freeze-thaw winters plus acidic condensate from gas furnaces have almost certainly done damage you can’t see from the top or bottom. A Level 1 visual check can only see the accessible ends of the flue. If you’re going to spend money on an inspection, spend it on the one that actually sees the full length. That’s the $349 – $549 Level 2, and we’ll show you the footage before anyone suggests a repair. Call (336) 863-3889 for a written quote.
Because the flue was likely sized for coal, not for a modern gas furnace. Most Collingdale twins were converted from coal to oil to gas over decades, and the flue cross-section stayed the same while the exhaust changed from hot, dry coal smoke to cool, wet gas byproducts. That oversized flue drafts poorly and lets moisture condense inside, corroding the liner from within, all while the exterior brick looks untouched. A camera scope is how we measure what’s actually happening inside. Call (336) 863-3889 and we’ll schedule a Level 2 inspection.
Creosote degree tells us how far the buildup has progressed, and in Collingdale the humid summers make even first-degree creosote a problem. First-degree is a flaky soot that absorbs moisture, turns acidic, and eats the firebox and damper surfaces before you ever light a fire in October. Third-degree is a hardened tar glaze that’s far harder to remove and usually means the chimney ran hot and stayed tarred for years. An annual inspection and sweep before winter keeps the degree low and the liner intact. We give you a written report with photos each time.
No. That’s a hard rule from Ruben Castellano, and it’s the reason Alcott Chimney Sweep operates the way it does. If we find a cracked liner, a spalled wythe, or a damaged crown, you’ll see it on camera with your own eyes before we quote anything. If the video doesn’t clearly show the problem, we won’t recommend the repair. Period. That’s the standard, and it applies to every home we inspect in Collingdale. Call (336) 863-3889 for a free estimate and a written price before any work starts.
