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.

AfterFast, Reliable Gas Fireplace Repair Across Villanova
Gas fireplace repair in Villanova usually means working on chimneys that are 70 to 100 years old, and that changes everything about the job. Most homes here were built between 1920 and 1955 from Wissahickon schist and brick, and their gas fireplace inserts were often tapped into flues never designed for them. That mismatch causes the draft, liner, and carbon monoxide issues we see most often on the Main Line. If your gas fireplace is acting up, call us at (336) 863-3889. We’re Alcott Chimney Sweep, and we’ve been diagnosing chimneys like yours since 2002.
Why Alcott Chimney Sweep Is Villanova’s Preferred Gas Fireplace Repair Company
Villanova homeowners call us because we show our work. When a tech drives onto a property off Spring Mill Road or Conestoga Road, they arrive with a written price already prepared for review after the diagnosis, not before they’ve told you what’s actually wrong. Ruben Castellano set the standard for that in 2002: no recommendation without camera evidence you can see with your own eyes. Especially with gas appliances on original clay-tile flues, that distinction matters. A lot of companies tell homeowners they need a liner or crown rebuild without ever putting a camera up the flue. We won’t do that. If we recommend a repair, you’ll see the video or photos that justify it.
Every technician who comes to a Villanova home has passed a background check and identity verification through the Threshold Standard. You’ll know their name and see their photo before we arrive, and they’ll show a photo ID badge at the door. For homeowners who are alone during the day, or parents with kids home from school, that’s not a nice-to-have. It’s the reason we do it, every time, no exceptions.
Our Gas Fireplace Repair crews serve the entire Villanova area, from the neighborhoods around Villanova University up through the estate roads near Radnor Township line. Dispatch and scheduling are coordinated from our Philadelphia office, but the techs working on your home are local to the Main Line and know these chimneys.
Our Gas Fireplace Repair Services in Villanova
Gas Fireplace Repair
When a gas fireplace in Villanova starts producing a weak flame, sooting up the glass, or spilling exhaust odor into the room, the cause is almost never what it looks like on the surface. On the 800 block of Mt. Moro Road, we were called to a stone colonial where exhaust odor was building up in the room whenever the fireplace ran. Our tech ran a camera up the flue and found cracked clay tile dividers between the fireplace flue and an adjacent boiler flue, a common defect in these 1920s multi-flue stacks. We repaired the divider with HeatShield and installed a properly sized DuraFlex liner. The draft restored, the smell disappeared, and the home passed Radnor Township inspection. That’s the kind of repair we do most often on Villanova estate homes.
Repair work typically runs $285 to $640 depending on what the camera finds: thermocouple or thermopile replacement, gas valve servicing, burner cleaning, or draft correction. Written price before any work starts, always.
Level 2 Chimney Inspection
Villanova homes with gas fireplaces should have a Level 2 inspection at least once every two years, and more often if the home has multiple flues sharing one chase. A Level 2 inspection includes a camera scan of the full flue interior, the smoke chamber, and the flue dividers. In Villanova’s 1920s and 1930s homes, those dividers are frequently cracked or missing mortar entirely, which Radnor Township treats as a code violation because it allows cross-contamination between fireplace and boiler flues. A Level 2 inspection in Villanova typically runs $195 to $350. We’ll hand you the camera footage, not just a checkbox report.
Flue Liner Installation
Most original Villanova chimneys are unlined or have deteriorating clay tile flues. Gas appliances produce acidic condensation that clay tile can’t handle, and unlined masonry flues are worse. We install stainless liners sized to the specific BTU output of your gas fireplace, not a one-size-fits-all tube. We use DuraFlex liners, the same product chimney professionals specify on the Main Line. A gas fireplace liner installation in Villanova runs $1,200 to $2,800 depending on flue height, diameter, and whether the chimney has offsets. We’ll show you the camera footage of the original flue before any liner work is recommended, so you know exactly why it’s needed.
Chimney Crown Repair and Waterproofing
The Philadelphia Main Line gets 25 to 35 freeze-thaw cycles per year, and that’s brutal on Villanova’s soft mortar crowns and stone chimney tops. Water gets into the crown, freezes, expands, and spalls the masonry. Once water reaches the gas fireplace components below, it corrodes burners, gas valves, and flue liners. We repair crowns with professional-grade materials and apply a breathable waterproof coating when the masonry allows it. Crown repair in Villanova runs $450 to $1,100 depending on the size of the crown and the condition of the underlying masonry.

Common Gas Fireplace Repair Problems We See in Villanova Homes
- Gas fireplaces vented into unlined or clay-tile flues not rated for gas. Homes built before 1955 rarely had gas-rated flues, and the acidic exhaust eats through clay tile. Camera inspection reveals missing mortar joints, and we often recommend a stainless liner at that point, with the footage to prove it.
- Cracked or missing flue dividers in multi-flue chimneys. A single exterior chimney chase often carries three or four separate clay-tile flues in Villanova, serving different fireplaces and sometimes an old boiler. When the dividers crack, exhaust from one flue bleeds into another. That’s a Radnor Township code violation, and it’s exactly the kind of defect that only a camera inspection catches.
- Deteriorating chimney crowns and soft mortar joints. Freeze-thaw cycling on the Main Line spalls brick and stone crowns faster than most homeowners realize. Once water gets in, it corrodes gas fireplace components and accelerates liner damage. This is the most common cause of “weird smell when the fireplace runs” calls we get in Villanova.
- Gas log sets installed in wood-burning fireplaces without proper draft testing. Gas burners need a different draft than wood fires. On older Villanova stacks with oversized or unrestored flues, a gas log set can spill combustion gases into the room even though it looks fine. We test draft on every gas repair call, not just when there’s an obvious problem.

FAQs – Gas Fireplace Repair in Villanova
The most likely cause in a Villanova home is a draft failure caused by a cracked flue divider, a deteriorated clay tile liner, or a gas appliance vented into a flue never designed for it. Each of these allows combustion gases to spill back into the room instead of rising through the flue. On the 800 block of Mt. Moro Road, we traced exhaust odor to cracked clay tile dividers between the fireplace flue and a boiler flue, a common defect in 1920s multi-flue stacks. If you smell exhaust, stop using the fireplace and call us at (336) 863-3889. We’ll run a camera up the flue and show you exactly what’s causing it.
Almost always, yes. Original Villanova chimneys were built with unlined masonry or clay tile flues. Gas fireplaces produce acidic condensation that clay tile and raw masonry cannot handle. A stainless liner sized to your specific gas appliance solves it. In Villanova’s 1920s and 1930s homes, if your chimney has multiple flues sharing one chase, the divider condition matters too. We’ll show you camera footage of the existing flue before recommending any liner work. A properly sized DuraFlex liner installation for a gas fireplace in Villanova runs $1,200 to $2,800.
Radnor Township inspection standards flag cracked or missing flue dividers in multi-flue chimneys as a code violation because they allow exhaust from one flue to bleed into another. In Villanova’s older estate homes, a single exterior chimney chase often contains three or four clay-tile flues serving different fireplaces and sometimes an old boiler. Cracked dividers between those flues can send boiler exhaust into a fireplace flue, or vice versa. That’s not a technicality. It’s a carbon monoxide risk. Every Level 2 inspection we perform in Villanova includes a camera assessment of flue divider condition, and we’ll show you what the camera sees. Call (336) 863-3889 to schedule one.
Every 12 to 24 months, depending on how often you use the fireplace and how old your chimney is. Villanova homes built between 1920 and 1955 with original clay-tile or unlined flues should be inspected annually until the flue condition is documented. Gas fireplaces in newer homes with stainless liners can usually go 24 months. A Level 2 inspection with a camera scan runs $195 to $350 in Villanova. If you’ve never had a camera inspection of your flue, call us at (336) 863-3889, and we’ll schedule one.
Yes, and this is not a negotiation. Every repair we recommend in Villanova comes with camera footage or photos of the actual defect in your actual chimney. Ruben Castellano built Alcott Chimney Sweep on that principle in 2002, and it’s never changed. If a flue liner is deteriorating, you’ll see the cracked tile. If a divider is missing mortar, you’ll see the gap. If a crown is spalling, you’ll see the water damage. Nothing is recommended without evidence you can see, and no work starts without a written price in your hand. Call (336) 863-3889 and we’ll show you what’s actually going on up there.
