Fast, Reliable Gas Fireplace Repair Across Pelham
Gas fireplace repair in Pelham typically runs $145 to $385 for most common fixes, and we can usually have a technician at your door within 48 hours of your call. Hadley Chimney Yonkers has been repairing gas fireplaces in Pelham’s older homes since 2003, and we know exactly what happens to a 1920s chimney when a modern gas insert vents into it. If your fireplace is acting up, call (914) 233-3156 and a live person will answer, day or night.
Why Hadley Chimney Yonkers Is Pelham’s Preferred Gas Fireplace Repair Company
Pelham homeowners call us because we show them what’s actually wrong before we quote a fix. That matters here more than almost anywhere else in Westchester. Pelham’s housing stock skews old: Colonial Revivals on the Esplanade, brick Tudors off Manor Lane, and the tight lots of Pelhamwood all tend to have original chimney stacks that were built for wood fires, not the gas logs installed decades later. Gas fireplaces vent differently than wood fires, and a flue that worked fine for one can be genuinely dangerous for the other.
We arrive in a tracked window, not a four-hour guess, and every repair comes with a written guarantee and a free second visit if the repair fails. That’s the 365-Day Done Right Promise, and it applies to every job we do in Pelham. Cory Mitchell, who leads our team, started Hadley Chimney Yonkers in 2003 and has spent those two decades refining a camera-first inspection process that catches problems other companies miss or misdiagnose.
We’re part of the Relay Home Co. family, which means every Pelham customer gets live arrival tracking, before-and-after photo documentation, and a written price before any work begins. No vague verbal quotes. No surprise upcharges when the tech is already in your living room.

Our Gas Fireplace Repair Services in Pelham
Flue Liner Inspection and Repair
The single most common gas fireplace issue we find in Pelham is a compromised flue liner. Homes in Pelham Manor and Pelham Heights built before 1930 often still have their original terra cotta clay tiles, and those tiles crack. Gas fireplaces produce lower-temperature exhaust than wood fires, but they also produce more water vapor. That moisture condenses inside the flue, soaks into old mortar, and freezes during Pelham winters. The freeze-thaw cycle widens hairline cracks into gaps, and suddenly combustion gases are seeping into wall cavities. We inspect with a camera, not a mirror and a flashlight, and you see the footage yourself.

Chimney Crown and Flashing Repair
Pelham’s humid continental climate is hard on chimney crowns. Snow sits on the crown, melts during the day, refreezes at night, and spalls the concrete. Once the crown cracks, water runs down the flue and onto your gas fireplace’s venting components. Rusted dampers, corroded flue pipes, and draft failures all trace back to water entry. We repair crowns with flexible sealant systems and replace flashing where it’s pulled away from the roofline. Given how many Pelham homes have original slate or cedar roofs, flashing work here requires care that run-of-the-mill crews don’t always bring.

Gas Fireplace Draft and Venting Diagnosis
A gas fireplace that won’t stay lit, produces a smell even when off, or sends soot staining up the mantel usually has a draft problem, not a gas valve problem. This is where Pelham homeowners get the most misleading diagnoses from other companies. The issue is almost always in the chimney: a blocked flue, a liner that’s too large for the appliance, or venting that was never sized correctly when the gas insert was installed. We use manometers and smoke tests to verify actual draft performance before recommending any repair. If you need a full Gas Fireplace Repair, our team can walk you through exactly what the diagnostics show.

Chimney Cap Installation and Replacement
Most Pelham chimneys have caps that are either missing, rusted through, or sized wrong for the flue. A proper cap keeps rain and snow out, blocks birds and squirrels, and actually helps stabilize draft. We stock Copperfield caps in our New York City dispatch office and can match the existing cap on older Pelham homes that have custom crown dimensions. Without a cap, every rainstorm in Pelham is quietly damaging your fireplace venting.

Trusted Brands We Service in Pelham
We work with the brands chimney professionals actually rely on: DuraFlex flexible liner systems, HeatShield ceramic repair compound, and Olympia Chimney caps and accessories. When a Pelham home needs a liner repaired rather than replaced, we use HeatShield’s ceramic resurfacing system to restore the flue without tearing out walls or rebuilding the stack. When a liner is beyond saving, we install DuraFlex. No off-brand parts, no whatever-is-cheapest-on-the-truck. Everything carries the manufacturer’s warranty plus our 365-Day Done Right Promise.
Common Gas Fireplace Repair Problems We See in Pelham Homes
- Cracked 1920s terra cotta flue tiles. In Pelham Manor especially, we find original clay liners that cracked under decades of thermal stress. The crack lets carbon monoxide and moisture into wall cavities, and it’s often misdiagnosed as a gas valve issue by companies that don’t run a camera.
- Deteriorated mortar joints in unlined flues. Older Pelham chimneys sometimes have no liner at all, just brick and mortar. Hot gas erodes the mortar, and eventually heat reaches the framing. This is a fire risk that stays invisible until someone does a proper Level 2 inspection.
- Freeze-thaw spalling on the chimney crown. Pelham winters cycle through dozens of freeze-thaw events. Water expands when it freezes, and old concrete crowns break apart. The water then drips onto gas fireplace venting, causing rust and draft failure that shows up as a smoky smell in the living room.
- Improperly sized flues for gas conversions. When a Pelham homeowner converts a wood-burning fireplace to gas, the original flue is often too large. The result: poor draft, soot buildup on the mantel, and combustion byproducts lingering in the room. We can resize the venting correctly.

What moves the number: whether your flue is accessible from the roof or requires a lift (common on the taller Pelham Heights homes), whether the liner damage is localized or full-length, and whether water damage has spread to the crown or flashing. You’ll get a written price before anyone starts work, always. Call (914) 233-3156 for an exact quote on your fireplace.
Here’s what we don’t do: recommend a three-thousand-dollar liner replacement based on a glance down the flue. In Pelham, where Century-old chimneys are the norm, other companies sometimes use the home’s age as a scare tactic. Our rule is simple: if we’re recommending a liner repair or rebuild, you’re watching the camera footage with us. You decide if the work makes sense. If it can safely wait, we’ll tell you that too.

FAQs – Gas Fireplace Repair in Pelham
The only way to know is a camera inspection, which we do on every diagnostic visit in Pelham. Original terra cotta clay liners from the 1920s were designed for wood fires, not the water-vapor-rich exhaust of gas appliances. Cracks that are invisible from the top or bottom show up clearly on camera footage. If your liner has hairline cracks but structural integrity is still good, HeatShield resurfacing usually fixes it for far less than a rebuild. Call (914) 233-3156 to schedule, and you’ll see the footage yourself.
Yes, in most cases. We use HeatShield’s ceramic resurfacing compound to seal cracked clay tiles from the inside, restoring the flue’s integrity without removing a single brick. This works well even on Pelham’s older chimneys, as long as the surrounding masonry is sound. If the chimney itself is compromised beyond the liner, we’ll show you that footage and walk through the options honestly. Sometimes the most cost-effective answer is a full liner replacement, and sometimes it’s a rebuild, but you’ll never be guessing.
Usually, yes. A gas fireplace that smells when off typically has a draft reversal or a blocked flue pulling combustion byproducts back into the room. In Pelham’s older homes, we also find odor coming from cracked flue tiles that let gases accumulate in wall cavities and seep back inside. We serviced a 1920s Tudor on Manor Lane where the homeowner smelled gas and saw soot staining around the mantel. A camera inspection showed a cracked terra cotta flue tile and deteriorated mortar joints. We installed a HeatShield resurfacing system and a copper chimney cap, then verified proper draft with a smoke test. The smell was gone that week. If you’re smelling gas, call us at (914) 233-3156 and we’ll diagnose it properly.
Once a year, even if you only burn a few times each season. Pelham’s freeze-thaw cycles damage chimney masonry regardless of use, and gas fireplaces produce enough water vapor to accelerate lining deterioration. An annual inspection catches small problems before they become a five-thousand-dollar rebuild. For Pelham homes with original 1920s liners, we recommend inspection every fall before heating season starts.
Yes, absolutely. Pelham gets around 45 inches of rain and snow each year, and every storm sends water down an uncapped flue. Water pooled at the base of your gas fireplace’s venting causes rust, draft failure, and in winter, ice damage. A proper cap also keeps birds and squirrels out, which is a real issue in Pelham’s tree-lined neighborhoods like Pelhamwood and Pelham Heights. We stock caps sized for original Pelham chimney flues and can install one during the same visit as your inspection.
