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.

Why Alcott Chimney Sweep Is Exton’s Preferred Chimney Inspection Company
Exton’s housing stock is a specific animal. Most of it went up between the late 1970s and early 2000s in planned subdivisions that repeat the same-era construction techniques street after street. Our techs work these neighborhoods weekly and know what to expect before we even climb the ladder: original clay-tile flues from the Reagan and Clinton eras, factory-built metal fireplaces that look fine from the living room but are riding on 40-year-old chase components, and gas logs retrofitted into stacks that were never sized for them.
That local knowledge matters when the alternative is a technician from a neighboring county who’s never opened a firebox off Whitford Chase and doesn’t know that 50% of what we flag in Exton comes back on camera as condensation damage inside oversized clay tiles. We don’t guess. We put a camera up the flue and show you the footage before we recommend a single repair.
We were founded in 2002 as part of the Threshold Group family, and every Alcott tech who steps onto an Exton driveway 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 – that’s not a courtesy, it’s how we’ve operated for over two decades. We carry HeatShield, Gelco, and Olympia Chimney materials on the truck, coordinate scheduling from our Philadelphia office, and answer every call with a live person, 24/7.
Chimney Camera Inspection in Exton
Chimney Camera Inspection in Exton is the difference between guessing what’s wrong above your damper and seeing it on a monitor in real time. We run a high-resolution camera up the flue from the firebox to the cap, and you watch the feed with us as we go. In Exton’s 30-to-50-year-old chimneys, this is rarely optional. The failure modes we find on camera – spalled clay tiles, separated prefab flue sections, condensation-eaten liner from a too-big gas-log retrofit – are almost always invisible from the living room.
What the camera catches
In a 1980s Exton colonial, the camera typically shows what the naked eye can’t: hairline vertical cracks in clay tiles that freeze-thaw cycling has opened up, mortar joints corroded by years of interior condensation, and factory-built flue sections that separated at a coupling decades ago. These are specific, documentable defects. We record the footage and include still images in your written inspection report, so nothing we recommend sits on a tech’s verbal say-so.
When Exton homeowners need it
A camera inspection costs $249 – $449 in Exton, depending on system complexity and whether we’re doing a full Level 2 with attic and crawlspace access. You want it before buying a home, after a chimney fire, when you’ve never had the liner evaluated, or when you’re switching a wood-burning fireplace to gas logs. If you’ve lived in your Exton home for a decade and never seen your flue from the inside, you need it this fall, before burning season starts.
Fireplace Inspection in Exton
Fireplace Inspection in Exton covers the whole system – firebox, damper, smoke chamber, flue, cap, and the chase on a factory-built unit – not just the inside of the firebox you can see with a flashlight. In Exton’s suburban build-out era, that usually means a prefabricated metal fireplace that is now 30 to 50 years old and well past its rated service life. These units don’t age gracefully. Firebox panels crack, flue couplings separate, and the chase top rusts out in our wet mid-Atlantic winters.
Prefab fireplaces and their expiration date
Most Exton homeowners don’t realize factory-built fireplaces carry a rated service life, typically 20 to 30 years. We regularly inspect units from 1985 that are still burning fires on original components. A full fireplace inspection includes removing the refractory panels enough to see the firebox floor and sidewalls, checking the flue connection point, and getting eyes on the chase top from a ladder. One Exton neighborhood alone, Whitford Chase, has enough identical 1988 prefab units that we can usually predict what we’ll find before we open the firebox.
Gas logs in a wood-burning firebox
Many Exton homes had gas log sets installed in the 1990s and 2000s without relining the original clay-tile flue. The tile was sized for a full wood fire, not a low-BTU gas appliance. The result is chronic interior condensation that degrades the liner from the inside out, a failure pattern we flag on camera in Exton zip codes on a regular basis. A fireplace inspection catches this before the liner fails completely, and we can often resize the flue or drop in a proper liner rather than tell you to stop using the fireplace.
Trusted Brands We Service in Exton
We install and service professional trade materials on Exton homes: HeatShield resurfacing for cracked clay liners, Gelco and Olympia Chimney components for caps and chase systems, and Famco venting for factory-built units. These are the brands chimney professionals specify, not box-store substitutes. If your Exton prefab needs a replacement refractory panel or your clay liner needs resurfacing, we’re not ordering parts from a catalog and making you wait two weeks – we stock the common ones on the truck and can usually complete the job in a single visit. We don’t improvise material substitutions, and we don’t install whatever’s cheapest. Same standard we’ve held since 2002.
Common Chimney Inspection Problems We See in Exton Homes
- Spalled clay tile flues from freeze-thaw cycling. Exton sits in the Great Valley where wet mid-Atlantic moisture combines with cold inland temperatures, and every winter the clay tiles expand and contract until sections begin to crack and flake. By the time you see tile shards on the damper ledge, the liner has been failing for years.
- Oversized flues from gas log retrofits. Exton’s 1990s and 2000s wave of gas log insert installs left original clay flues in place, and an 8×12 tile stack venting a small gas appliance never gets hot enough to push moisture out. The condensation sits inside the tile and degrades it from the inside.
- Separated factory-built flue sections. In prefab units from Exton’s original 1970s – 1990s build-out, the flue sections are often coupled with friction-fit connections that shift over 40 years of thermal cycling, north-south runs through cold attics, and general settling. A separated section means exhaust escapes into the chase instead of up and out.
- Rust and water entry through deteriorated chase tops. Prefab chases on Exton homes were often capped with a simple galvanized top that rusts through after 20 to 30 years in our climate. Water gets in, rusts the flue collar, and eventually compromises the firebox itself.
Pricing for Chimney Inspection in Exton, PA
A Level 1 inspection in Exton, which covers the accessible portions of the fireplace and flue with no special tools, typically runs $199 – $249. A Level 2 inspection, which is what you need for a real estate transaction or any system that’s been modified, runs $349 – $449 and includes full camera documentation. A Level 3, where we open a wall or chase to access hidden components, starts around $700 and is quoted in writing before any work begins. What affects your price: prefab versus masonry, accessibility of the chase, whether we need a second tech for ladder work on a steep pitch, and whether previous repairs left components that are hard to access. Every inspection comes with a written price before we start, a written report with photos after, and a full year of accountability under our 365-Day Done Right Promise.

FAQs About Chimney Inspection in Exton
Because the parts that fail first are the parts you can’t see from the living room. In Exton’s 1980s construction – particularly the colonial and traditional builds off Routes 30, 100, and 202 – the factory-built fireplaces and clay tile liners are now 35 to 45 years old. Clay spalls from the inside, prefab flue sections separate at couplings, and gas log retrofits cause interior condensation that eats liner from within. None of these show up as a visual problem in the firebox until the damage is advanced. A camera inspection documents the actual condition of the flue so you’re not relying on a visual guess. Call (336) 863-3889 to schedule yours.
Very often, yes. The original clay flue in a 1970s – 1980s Exton home was sized for a full wood fire, not a small gas log set. The oversized tile venting a low-BTU appliance produces chronic interior condensation, which degrades the liner from the inside out. We’ve documented this in subdivisions across Exton, including in homes where the liner looked fine from the firebox but spalled badly mid-flue. A camera inspection confirms whether your retrofit is venting properly or slowly destroying the liner. We’ll show you the footage before we recommend anything text and a fix may be simpler than you think.
Exton sits in the Great Valley of Chester County, where wet winters and repeated freeze-thaw cycles put clay tile flues under constant expansion and contraction stress. When water from a cracked crown or rusted chase top gets into the tile, each freeze widens hairline cracks into structural gaps. After 40 winters, tiles spall and sections collapse, and that damage sits hidden above the damper until a camera goes up. This is the single most common failure we document in Exton masonry fireplaces built before 1990.
A Level 1 inspection checks the accessible portions of the fireplace and flue without special tools or camera work; it’s the right choice for an annual maintenance check on a system that hasn’t changed. A Level 2 inspection adds a full camera scan of the flue interior plus attic and crawlspace access, and it’s required for a real estate transaction, any system that’s been modified (including adding gas logs), or any fireplace that hasn’t been inspected in years. In Exton, most homes built before 2000 with original clay tile or factory-built flues warrant a Level 2. We’ll tell you which one fits your situation before we book, and the price is written down before we arrive.
Yes. We don’t recommend a repair we can’t show you on camera, and we don’t quote a repair you haven’t seen evidence for. If we flag a separated flue section in your Whitford Chase prefab or condensation damage in your gas-log clay liner, you’ll see the footage on our monitor before any work is quoted. We write the price, you approve it, and nothing gets done without your sign-off. If we do repair it, the work carries a written guarantee for a full 365 days – if it fails within that window, the second visit is free. Call (336) 863-3889 and we’ll inspect before we ever recommend a fix.
