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 Yeadon’s Preferred Gas Fireplace Repair Company
Most Yeadon homes were built between 1910 and 1945, and their chimneys were engineered for coal, not gas. That matters. A gas fireplace vented into an unlined or oversized clay flue behaves differently than one in a newer suburban house, and a technician who doesn’t know the difference will chase the wrong problem. Our Gas Fireplace Repair team sees Yeadon’s specific conditions every week: crumbling clay tile liners, weak draft from oversized flues, and mortar joints failing from decades of freeze-thaw cycles. We diagnose the actual cause before recommending any repair, and we prove it with camera footage you can watch yourself.
Ruben Castellano built Alcott Chimney Sweep in 2002 around a simple idea: show the customer exactly what’s wrong before asking them to spend a dollar. Every technician is background-checked and identity-verified under the Threshold Standard. You’ll get the technician’s name and photo before the visit, and they’ll show a photo ID badge at the door. Every job comes with a written price before any work starts, a written guarantee on every repair, and a free return visit if the repair fails within 365 days. That’s the 365-Day Done Right Promise, and it’s not an upsell. It’s how we’ve worked since day one.
Our Gas Fireplace Repair Services in Yeadon
Level 2 Camera Inspection
A Level 2 camera inspection in Yeadon runs $149 to $289 and is the single most important step before any gas fireplace repair. We run a camera through the full flue and show you exactly what it sees: cracked clay tile, missing mortar, creosote glaze, or a liner that was never installed in the first place. On Yeadon’s row homes and twins, the original coal-era flue is often two to three times larger than what a modern gas fireplace needs, which kills draft and lets moisture and creosote build up. Camera evidence means you never take our word for it. You see the problem with your own eyes.

Flue Liner Evaluation and Replacement
Clay tile liners in Yeadon’s 80-to-110-year-old chimneys crack and spall because they were sized for coal combustion, not sealed gas appliances. We evaluate every liner before recommending anything. When replacement is needed, we install DuraFlex or HeatShield systems, the same professional materials chimney professionals specify, with typical Yeadon jobs ranging from $1,100 to $3,600 depending on flue height and roof access. A properly sized liner restores draft, keeps carbon monoxide moving out of the house, and prevents condensation from eating the interior brickwork. We never recommend a liner without showing you the camera footage first.

Firebox and Damper Repair
Gas fireplaces in Yeadon row homes often sit inside fireboxes that once burned coal, and the mortar joints around them take a beating. Between the humidity from the Cobbs Creek corridor and Delaware County’s hard freeze-thaw cycles, mortar spalls and cracks. We repair firebox masonry, replace failing dampers, and seat gas logs properly so the flame burns clean and the exhaust drafts correctly. Typical firebox repairs run $175 to $490 in Yeadon, depending on the extent of the masonry work.

Gas Log and Burner Service
If your gas logs won’t light, light unevenly, or produce sooty flames, the burner assembly or thermocouple is usually the culprit. We service and replace thermocouples, thermopiles, pilot assemblies, and burner pans, and we clean burner ports so the flame pattern is even. Most burner service calls in Yeadon run $145 to $275 in parts and labor. We carry parts for Famco and Copperfield gas log sets and can source manufacturer-specific components for most major brands.

Trusted Brands We Service in Yeadon
We service and install gas fireplaces and components from the brands chimney professionals actually use: Copperfield gas log sets, Famco burner systems, DuraFlex liner systems, and HeatShield resurfacing. These aren’t box-store substitutes. They’re trade materials specified for the specific conditions Yeadon’s older chimneys present. We keep common parts stocked for faster turnaround on Yeadon jobs, so you’re not waiting on a shipment for a pilot assembly when the temperature drops in November.
Common Gas Fireplace Repair Problems We See in Yeadon Homes
- Oversized flues without liners. Yeadon’s pre-WWII chimneys were built for coal, and the flues are often twice the diameter a gas fireplace needs. That weakens draft, lets exhaust linger, and accelerates creosote buildup on the smoke chamber walls. A correctly sized liner fixes this at the root.
- Clay tile liner failure. After 80 to 110 years of thermal cycling and moisture intrusion, original clay tile liners crack, shift, and spall. On camera, it looks like the flue is shedding. If the liner has failed, venting a gas fireplace through it without repair is a carbon monoxide risk, not a cosmetic issue.
- Efflorescence and interior spalling. Homes on Yeadon’s eastern edge near Cobbs Creek sit in a persistently moist microclimate. White mineral staining on brickwork outside your house often means water is moving through the chimney from the inside, weakening mortar around the firebox. It looks cosmetic from the street. On camera, the interior joints are crumbling.
- Weak draft and gas odor on startup. Row homes packed tightly together create odd pressure zones. A gas fireplace that drafts fine in a detached house may backdraft in a Yeadon twin when the neighbor’s exhaust fan runs. This often points to liner sizing or a failing damper, both of which we evaluate on site.

FAQs – Gas Fireplace Repair in Yeadon
In Yeadon, poor draft usually points to an oversized flue, not a dirty one. Your chimney was built for coal, and the flue diameter is often twice what a modern gas fireplace needs. That oversized flue can’t maintain proper draft velocity, so exhaust lingers and the fireplace under-performs even when it’s spotless. The fix is usually a properly sized liner, and we’ll show you the camera footage that proves it before we touch anything. Call (336) 863-3889 for an inspection.
Yes, and here’s why: in Yeadon’s older chimneys, the liner and mortar are the issue even when the fireplace is clean. Gas combustion produces acidic condensate that attacks aging clay tile and mortar throughout the year, even in summer. An annual Level 2 camera inspection in Yeadon runs $149 to $289 and catches spalling and liner failure before they become safety hazards. If nothing is wrong, you’ve spent a small amount for certainty. If something is wrong, you’ve caught it early. Call (336) 863-3889 to schedule.
White staining on brick is efflorescence, and in Yeadon it’s especially common on homes near the Cobbs Creek lowlands. The creek valley’s shade and humidity keep those chimneys wet long after rainfall, and water moving through the masonry carries mineral salts to the surface. That same moisture is why interior mortar joints in that part of Yeadon often crumble on camera even when the exterior looks intact from the street. If you’re seeing white stains, schedule a camera inspection before the damage spreads.
Almost always, yes. In Yeadon’s older row homes, the brick chimney itself is rarely the problem. The liner, the damper, the firebox mortar, or the burner assembly is. Most repairs replace or repair those components, not the entire masonry stack. We only recommend a full rebuild in cases of severe structural compromise, and even then we’ll show you exactly why on camera. You’ll never be talked into a major job you can’t verify. Call (336) 863-3889 for a straight answer.
Yeadon’s chimneys are 80 to 110 years old, built for coal, and rarely relined when homes converted to gas. The original flues were oversized for modern appliances, and decades of hot gas exhaust followed by Delaware County’s freeze-thaw cycles and Cobbs Creek moisture have accelerated the cracking and spalling. Newer suburbs have newer chimneys sized for modern appliances. Yeadon has original clay tile and century-old mortar still doing a job they were never designed for. That’s why we emphasize camera inspection here more than anywhere else we work.
