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.

What makes Lansdowne different from the newer suburbs isn’t the fireplaces themselves. It’s the chimneys they’re connected to. The borough’s housing stock, built mostly between 1895 and 1930 as a streetcar suburb, left behind coal-era chimney stacks with clay-tile flues that were sized for coal, not for the gas inserts people use today. That mismatch creates problems in Lansdowne that a technician working mostly in, say, Media or Broomall rarely sees. So when we diagnose a gas fireplace here, we start with the flue, not the firebox.
Why Alcott Chimney Sweep Is Lansdowne’s Preferred Gas Fireplace Repair Company

The same framing and venting problems show up again and again here, and we know what to look for before we even ring the bell.
Every customer gets the same thing regardless of the job size. A background-checked, identity-verified technician whose name and photo are sent to you before arrival. Written pricing before any work starts. A written guarantee on every repair, and if that repair fails, the second visit is free.

Level 2 Camera Inspection Before Any Repair Quote
In Lansdowne, we will not quote a gas fireplace repair until we’ve run a camera through the flue. This is not a formality. On a borough home with an original clay-tile liner, the difference between a $180 fix and a $2,800 problem often only shows up on video. The oversized flues common to Lansdowne’s coal-era stacks can hide cracked tile joints, partial blockages, and moisture damage that push exhaust back into the room. We record the footage, walk you through it, and you decide from there. Nothing gets recommended without evidence you can see with your own eyes.

HeatShield Flue Liner Resurfacing
When a Lansdowne chimney has cracked or spalled clay tile, tearing the whole stack apart isn’t always necessary. HeatShield resurfacing rebuilds the interior flue surface with a ceramic coating that handles gas-appliance exhaust temperatures and restores a continuous, correctly sized passage. For the borough’s oversized legacy flues, this often means relining only the upper section where the damage sits, rather than dropping a new liner the full height. We use HeatShield products because they’re specified by chimney professionals for exactly this application, not picked up at a home center.

Draft, Damper, and Cap Correction for Oversized Flues
Gas fireplaces in Lansdowne are frequently connected to flues that are simply too big. A flue sized for a coal furnace has two or three times the cross-section a modern gas insert needs. Exhaust cools too quickly, stalls, and drops back into the living room. Fixing that can mean a correctly sized cap, a damper adjustment, or partial relining to restore the right draft. On Owen Avenue we worked on a Heat & Glo insert that kept shutting off after 20 minutes and leaving a sooty smell. The camera showed a liner that was oversized for the insert, cracked at a mortar joint two courses up, and partially blocked by a squirrel nest. We removed the nest, repaired the tile section with HeatShield, reset the damper and cap, and the fireplace drafted cleanly. The owner watched the entire recording before approving anything further.

Thermocouple, Pilot, and Ignition Repairs
When the flue checks out but the fireplace still won’t stay lit, the culprit is usually the thermocouple, the pilot assembly, or the ignition module. These are straightforward repairs, typically $145 – $260 in Lansdowne depending on brand and part availability. We carry common parts for major gas fireplace brands and source specialty components through our professional supply network, which keeps turnaround fast for Lansdowne customers.

Trusted Brands We Service in Lansdowne
We service and install gas fireplaces and venting components from the brands chimney professionals actually specify: Olympia Chimney caps and dampers, Famco venting systems, Copperfield chimney products, and DuraFlex liner systems. For Lansdowne homeowners, that matters because these components are built for the freeze-thaw conditions and older masonry common here. What we don’t do is substitute big-box parts to hit a lower price. The repair gets done with materials rated for the job, and the written guarantee stands behind them.
Common Gas Fireplace Repair Problems We See in Lansdowne Homes
- Backdrafting into the living room. Coal-era clay-tile flues are oversized for gas inserts, so exhaust cools, loses velocity, and stalls before it reaches the top. The symptom is a sooty smell in the room after 20 or 30 minutes of burn time.
- Water damage from heaving crowns and cracked mortar. Delaware County gets 30 to 50 freeze-thaw cycles per winter. Lansdowne’s older exposed chimney crowns absorb moisture that expands with each cycle, opening joints above the roofline and sending water down into the firebox and damper area. Rusted assemblies and stained smoke chambers are what keep repair bills high here.
- Shared-stack problems in brick twins. Many of Lansdowne’s classic twins share one interior chimney stack with two flues on either side of a party wall. A cracked liner or partial blockage in one unit’s flue can push combustion gases into the neighboring home. A single-unit inspection misses this entirely, which is why we coordinate access across both sides before certifying either flue.
- Pilot and thermocouple failures from corrosion. Moisture that tracks down through cracked crowns and open joints eventually reaches the firebox. When it does, pilot assemblies corrode, thermocouples fail, and the fireplace either won’t light or shuts off mid-burn. Replacing the part without addressing the water source just means replacing it again next season.

FAQs – Gas Fireplace Repair in Lansdowne
In Lansdowne, that smell is almost always the chimney. Gas fireplaces connected to coal-era clay-tile flues are vented into a passage that’s too large to maintain draft, so exhaust cools, stalls, and spills back into the room. The fireplace itself may be working correctly. The fix is a camera inspection to see what’s actually happening in the flue, then correcting the draft with the right cap, damper, or liner resurfacing. We show you the footage before recommending anything. Call (336) 863-3889 to schedule an inspection.
Yes, and this is a Lansdowne-specific condition we see regularly. Brick twins in the borough frequently share a single interior chimney stack with two flues on either side of a party wall. A cracked liner, animal nest, or partial blockage in one unit’s flue can push combustion gases into the neighboring home. If your neighbor’s fireplace has been acting up or if you smell exhaust you can’t explain, we coordinate an inspection across both sides of the party wall before certifying either flue as safe. Call (336) 863-3889 and we’ll walk you through exactly how that works.
The answer is footage, not opinion. We run a Level 2 camera inspection through the flue before quoting any liner work. You watch the video with us. If the tile joints are cracked, spalled, or missing, the footage shows it. If the flue is blocked with creosote and debris, that’s a cleaning, not a liner. If a damaged section is confined to a few feet of the stack, HeatShield resurfacing may handle it without a full liner replacement. In Lansdowne’s older homes, we often find the original clay tile is oversized for the gas insert, and the real fix is correcting the draft, not replacing everything. Come see the footage yourself before spending a dollar. Call (336) 863-3889 for an inspection with a free estimate.
Spring is actually a good time for gas fireplace inspection in Lansdowne, because late winter and early spring are when freeze-thaw damage shows up most clearly. The borough’s exposed chimney crowns and above-roofline brickwork take on moisture all winter, and by March the heaving, cracking, and opened mortar joints are visible. Waiting until October means discovering in burning season that water got into the firebox over the summer, rusted the assembly, and left you with a repair during the busiest stretch of the year. An off-season inspection costs less to schedule and leaves you with a clear flue before the first cold night. Call (336) 863-3889 anytime.
Yes, and in Lansdowne the risk is compounded by the borough’s older shared stacks. A gas fireplace produces carbon monoxide with every burn. When the chimney drafts properly, that gas exits above the roofline. When a flue is partially blocked, cracked, or oversized, exhaust can stall and spill back into the living space. In a brick twin with a shared stack, it can also push into the neighboring unit. Carbon monoxide is odorless and colorless, so the first sign is often a headache or a sooty smell, not an alarm going off. This is why we camera-inspect every flue before quoting any gas fireplace repair in Lansdowne. If you haven’t had your flue checked, call (336) 863-3889 and we’ll come out. A live person answers, and the estimate is free.
