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 Old Greenwich
Gas fireplace repair in Old Greenwich usually costs between $190 and $480 for common fixes like thermocouple replacement, pilot assembly cleaning, and burner adjustment. More involved work, like replacing a corroded damper or installing a stainless chimney cap near Greenwich Point, runs $300 to $900. We’re Alcott Chimney Sweep, founded in 2002 and led by Ruben Castellano, and we’ve been repairing gas fireplaces in Old Greenwich long enough to know one thing: the Sound changes everything. Salt air, marine moisture, and nor’easter spray attack outdoor chimney components here on a timeline that inland towns never experience. If your fireplace won’t stay lit, smells like gas, or has a damper that won’t budge, call us at (336) 863-3889. We’ll give you a written price before any work starts, and you’ll know exactly who’s coming to your door before we arrive.
Why Alcott Chimney Sweep Is Old Greenwich’s Preferred Gas Fireplace Repair Company
Old Greenwich homeowners call us for gas fireplace repair because we understand what this specific stretch of coastline does to chimney components. The same home ten miles inland in Greenwich’s backcountry might get fifteen years out of a stainless chimney cap. Here, four or five years is the reality near Tod’s Point. That’s not a defect. That’s salt spray off Long Island Sound working on metal every single day. Ruben and our techs know which components fail first on colonials and Tudors along Shore Road, Binney Park, and the streets branching off Sound Beach Avenue. Our Gas Fireplace Repair team arrives with the parts that actually matter here: marine-grade stainless caps, replacement dampers sized for 1920s-era flues, and liner repair materials like HeatShield and Gelco that hold up to coastal moisture.
Every Alcott technician is background-checked and identity-verified under the Threshold Standard. Before anyone steps onto your property, you get their name and photo. When they knock, they show photo ID at the door. No exceptions. This matters to homeowners who are often home alone, parents managing nap schedules, and older residents who want to know exactly who’s walking up the driveway. You’ll also get a written price before work begins, a written guarantee on every repair, and a free return visit if that repair fails within 365 days. That’s our 365-Day Done Right Promise, and it’s included on every job in Old Greenwich.
Our Gas Fireplace Repair Services in Old Greenwich
Gas Fireplace Repair
Gas fireplaces in Old Greenwich fail differently than wood-burning units. The salt-heavy air that rolls off the Sound corrodes thermocouples, pilot assemblies, and burner tubes at an accelerated rate. We regularly find gas fireplaces in 1930s colonials along Shore Road that won’t stay lit because moisture has worked its way into the firebox and rusted the pilot assembly. We diagnose the exact failure, show you what’s wrong, and give you a written price before touching a tool. You won’t get recommended for work that can safely wait.
Chimney Caps & Dampers
This is the single most common repair we perform in Old Greenwich, and it’s the one homeowners never expect. Stainless steel caps and dampers that would last a decade or more inland corrode through here in four to five years. Constant salt spray off the Sound pits the metal, then water gets in, soaks the firebox, and seizes the damper solid. We replace galvanized and even stainless caps with marine-grade components and install dampers that can handle the coastal environment. If your cap was installed within the last few years and already looks rough, that’s not bad luck. That’s Old Greenwich.
Flue Liner Repair
Most Old Greenwich homes built between 1910 and 1955 still have their original clay tile liners. Those liners are now 60 to 100 years old. Add marine moisture, freeze-thaw cycles that spall the brick around them, and you get cracked tiles and debris that block the gas flue draft. We repair these with HeatShield resurfacing or Gelco cast-in-place liners rather than jumping straight to a full rebuild. Both products are what chimney professionals specify for coastal applications, and both restore a smooth, insulated flue path without tearing out your chimney.
Chimney Crown & Flashing Repair
Nor’easters drive rain horizontally into Old Greenwich chimneys at angles a standard interior Connecticut rain event never would. Crowns crack. Flashing pulls away from the roofline. The result is water where it shouldn’t be, and a gas fireplace that won’t perform. We repair crowns with proper expansion joints and replace flashing with materials rated for marine exposure. The fix is straightforward, but it has to be done right the first time because the next nor’easter is always coming.

Trusted Brands We Service in Old Greenwich
We install and service gas fireplace components from the brands chimney professionals actually specify: HeatShield for flue liner resurfacing, Gelco for cast-in-place repair, plus Olympia Chimney and Famco dampers and caps. These are pro-grade trade brands, not box-store substitutes. Because we work Old Greenwich regularly, we keep the marine-grade versions of these products staged and ready. That means shorter turnaround when your fireplace quits in February and you’d rather not wait a week for parts.
Common Gas Fireplace Repair Problems We See in Old Greenwich Homes
- Corroded stainless chimney caps: This is our number-one call from streets near Greenwich Point and Tod’s Point. Salt spray pits even quality stainless in four to five years, letting water straight down the flue and into the firebox. Owners are often shocked because the cap looks new to them. It isn’t new. It’s marine-aged.
- Seized dampers from salt-water infiltration: When a failed cap lets moisture in, the damper is usually the first casualty. Rust welds the mechanism solid, and you get a fireplace that won’t draft properly or smells faintly of gas when off. We free or replace them, then fix the actual water entry so it doesn’t happen again next season.
- Cracked clay tile liners from freeze-thaw spalling: Salt-laden water saturates Old Greenwich brick and mortar before winter temperatures arrive. When it freezes and expands, the brick spalls, and the original clay tile liner cracks. Debris falls, the gas flue draft gets blocked, and the system stops working safely. HeatShield resurfacing fixes this without a full rebuild.
- Pilot and thermocouple corrosion: Gas fireplaces near the Sound draw in salt-heavy combustion air. Over time, sensors and pilots corrode faster than the same unit inland would. The good news: these are usually straightforward repairs once we confirm the venting is sound and the firebox hasn’t been water-damaged.

FAQs – Gas Fireplace Repair in Old Greenwich
The most likely culprit is a corroded thermocouple or pilot assembly, and in your location, salt-air corrosion is the usual cause. The same moisture that pits your chimney cap also attacks the small components inside your firebox. We’ll confirm with a quick diagnostic, show you the failed part, and give you a written price before replacing it. Most pilot and thermocouple work in Old Greenwich runs $190 to $340. Call (336) 863-3889 for an exact quote.
Annually, and we recommend scheduling it in late summer or early fall before burning season. Homes within a quarter mile of Long Island Sound, especially near Tod’s Point and Shore Road, need closer monitoring because salt spray degrades caps, dampers, and crowns on an accelerated timeline. If your home sits on the water, consider a mid-winter visual check after the first few nor’easters.
Because it was likely a standard stainless cap, not a marine-grade one, and Old Greenwich salt air punishes standard stainless relentlessly. Constant salt spray off Long Island Sound causes pitting and through-corrosion in four to five years, even when the cap looks structurally fine from the ground. We replace it with a marine-grade cap and note the install date so you know when to expect the next replacement window.
Water staining on the ceiling near the chimney, dampness or efflorescence on the brick, rust streaks running down from the cap, and a gas fireplace that won’t draft are the tell-tale signs. On coastal homes, flashing can separate from the roofline after a nor’easter without being obvious from the ground. We inspect, show you photos, and give you a written price for repair before any work proceeds.
Yes, in most cases. HeatShield resurfacing or a Gelco cast-in-place liner restores a smooth, insulated flue path without tearing apart your chimney. We confirm the extent of the cracking with a camera first, show you the footage, and only then recommend the appropriate repair. Full rebuilds are rare, and we won’t recommend one unless the structure itself is failing.
Why Old Greenwich’s Salt Air Makes Gas Fireplace Repair Different
Here’s what most Old Greenwich homeowners don’t realize until a fireplace quits working: the Sound is the single biggest variable in your chimney’s lifespan. Salt-laden marine moisture saturates porous brick and mortar all year. Then winter comes, the water freezes, and the brick spalls. The same salt that pits your stainless cap also corrodes your damper, your flashing, and the small metal bits inside your gas fireplace. Inland Fairfield County homes deal with weather. You deal with weather plus a corrosive marine environment. That’s why we stock marine-grade components for Old Greenwich specifically, and why we recommend inspection cycles that reflect your actual exposure, not a generic Connecticut schedule.
We saw this up close on a 1930s colonial off Shore Road near Tod’s Point. The gas fireplace wouldn’t stay lit, and the damper wouldn’t move. The original clay flue liner had cracked, and the stainless cap had pitted through from salt-air exposure, letting water soak the firebox and corrode the damper assembly. We fitted a new marine-grade cap, installed a HeatShield flue liner repair, and freed the damper. The fireplace drafted properly and burned safely again. The homeowner had replaced that cap only four years earlier. That’s the marine timeline, and it’s the only timeline that matters in Old Greenwich.
