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 Jessup
Gas fireplace repair in Jessup typically runs $185 – $475 for most common fixes like thermocouple replacement, pilot assembly work, or valve service. More involved repairs, like flue relining or chimney cap replacement after a storm, land in the $900 – $2,800 range depending on what the camera inspection actually shows. We quote a written price before any work starts, so you’re never guessing at the total. If your fireplace smells like something’s burning when it shouldn’t, or the flame won’t stay lit, call us at (336) 863-3889. We’ll send a technician whose name and photo you’ll see before they knock on your door.
Jessup sits in a strange spot, and we mean that literally: the Howard County – Anne Arundel County line runs right through the neighborhoods along Route 1. That means the house on one side of the street may need Anne Arundel paperwork for a liner permit while the house next door falls under Howard County’s building department. When you call a company that doesn’t work Jessup regularly, they miss this. We don’t.
Most of what we see in Jessup homes is tied to two things: storms and an old oil-to-gas conversion story. Wind and rain get past caps that shifted in a nor’easter, water sits in the smoke chamber, and the first cold night of the season you smell something that isn’t quite right. We’ll get to the specifics below, but the short version is this: we’ve been repairing gas fireplace repair problems in this exact housing stock for years, and we know which failure shows up first in a 1960s rambler off Guilford Road versus a split-level north of Dorsey Run Road.
Why Alcott Chimney Sweep Is Jessup’s Preferred Gas Fireplace Repair Company
Alcott Chimney Sweep has been serving homeowners since 2002, and we’ve built our Jessup work around one uncomfortable truth: opening your door to a stranger is harder when that stranger is going to be in your living room, near your gas line, for an hour. Ruben Castellano, who leads our team, set the standard early: every technician is background-checked, identity-verified, and announced to you by name and photo before the truck leaves our Baltimore scheduling office. That’s the Threshold Standard, and it’s not an upgrade you ask for. It’s just how we operate.
When we arrive in Jessup, the technician at your door is wearing a photo ID badge that matches the name and picture you already received. No exceptions. We know a lot of our Jessup customers are home alone during the day or have young kids in the house, and we don’t treat that as a footnote. We treat it as the reason the process exists in the first place.
Our gas fireplace repair in Jessup work is backed by the 365-Day Done Right Promise. Every repair gets a written guarantee. If the repair fails within the coverage period, the second visit is free.

If something smells like smoke at 11 p.m. in a Jessup winter, you won’t get a voicemail.
Our Gas Fireplace Repair Services in Jessup
Gas Fireplace Draft and Venting Diagnosis
A gas fireplace that won’t draw in Jessup is rarely one problem. It’s usually two or three stacked on top of each other. The house was built in the 1950s or 1960s, the chimney was sized for an oil burner, and someone converted to gas without relining the flue. Now the flue is oversized for the appliance, the draft is weak, and combustion byproducts linger instead of venting. We diagnose this with a camera inspection, not guesswork. You see the footage. We point at the screen and explain what’s happening in plain English.
Chimney Cap and Flashing Repair After Storm Damage
Jessup gets real weather. Freeze-thaw cycles along the Patuxent River floodplain crack mortar, and a hard windstorm can shift a chimney cap enough to let rain pour into the smoke chamber. When that water reaches the ceiling below, it reads as a stain, and homeowners often blame a roof leak. We find it’s the chimney more often than you’d think. We’ll reset or replace the cap, repair the flashing at the roof line, and seal the crown so the next storm doesn’t undo the work. This is not a one-visit patch job; we inspect the whole top of the chimney while we’re up there.
Flue Liner Replacement for Oversized, Unlined Converted-Gas Flues
This is the single most common structural repair we do on older Jessup homes. The original flue was built for an oil burner. Gas was piped in later. Nobody relined the chimney. The result: an oversized, unlined flue that drafts poorly and collects acidic condensate that eats mortar from the inside out. We install correctly sized liners from DuraFlex, Famco, or Olympia Chimney, the same brands chimney professionals specify. The liner resolves the draft failure and protects the masonry from further condensate damage. A properly sized liner is not an upsell; it’s the fix for a conversion that was never finished.
Fireplace Gas Valve, Thermocouple, and Pilot Assembly Service
Sometimes the problem is simpler. A thermocouple that’s worn out, a pilot that won’t stay lit, a gas valve that’s sticking. These are the repairs that run at the lower end of the pricing spectrum, and they’re often done in a single visit if we have the part on the truck. We stock common parts for the brands Jessup homes typically have, which cuts down on wait time. If it needs a part we don’t carry, we order from our local supply network and don’t leave you without a working fireplace longer than necessary.

Trusted Brands We Service in Jessup
We service and install professional-grade components from Gelco, HeatShield, and Famco, among others. These are not box-store substitutes. They’re the materials a working chimney professional specifies because they survive freeze-thaw cycles and acidic condensate, the two things Jessup’s humid summers and hard winters throw at a chimney every year. We stock common parts locally for faster turnaround on Jessup calls, and when a repair calls for a liner or cap from a specific manufacturer, we’ll tell you the brand by name before we order it. You’ll know exactly what’s going into your home, which is exactly how it should be.
Common Gas Fireplace Repair Problems We See in Jessup Homes
- Back-drafting after an oil-to-gas conversion. The flue was sized for an oil burner, not a gas fireplace. The oversized flue can’t maintain draft, and combustion gases push back into the room. We see this on ramblers and split-levels throughout the Route 1 corridor, and it requires a reline, not a tune-up.
- Water intrusion through a displaced chimney cap. A windstorm shifts the cap, rain gets into the smoke chamber, and the homeowner notices a ceiling stain weeks later. By the time we’re called, the stain is the only visible symptom. The camera finds the rest.
- Flashing failures at the roof line. Freeze-thaw cycles in Jessup expand and contract the metal until the seal breaks. Water tracks down the outside of the flue, mixes with acidic condensate, and accelerates mortar deterioration. We repair the flashing and assess the flue while we’re on the roof.
- Failed thermocouples and pilot assemblies. A pilot that won’t stay lit is annoying, but it’s also a sign the thermocouple has worn out. This is a routine repair, and it’s one of the most common calls we get from Jessup homeowners before the first fire of the season.

We were called to a 1960s rambler off the Route 1 corridor in Jessup where a converted gas fireplace had been back-drafting, leaving a faint ceiling stain the homeowner blamed on rain. Our tech found a displaced chimney cap and failed flashing letting water into the smoke chamber, plus an oversized unlined flue sized for the home’s old oil burner. A Level 2 inspection confirmed condensate damage at the mortar joints. We reset the cap, repaired the flashing, and lined the flue with a correctly sized DuraFlex liner, and the draft and stain issue cleared. That’s a typical Jessup job for us: three problems, one visit, all visible on camera before we start.
Why the Howard – Anne Arundel County Line Matters for Your Repair
This is the part most companies miss, and it’s the reason a generic gas fireplace page won’t help you. Because the Howard – Anne Arundel county line cuts directly through Jessup’s neighborhoods, two gas fireplaces on the same Route 1-side street can fall under different permitting authorities. A flue liner or vent repair here has to be scoped to the correct county’s code before a single part is ordered. We know which side of the line you’re on because we work Jessup every week, not once a season. We pull the right paperwork the first time, which keeps your repair from stalling at inspection.
Many of those same flues were originally sized for oil burners and later converted to gas. That leaves an oversized, unlined chimney that fails draft and collects acidic condensate. In a house on the Anne Arundel side, the permitting path is one process. On the Howard side, it’s another. Same street, different rules. We handle both so you don’t have to think about it.

FAQs – Gas Fireplace Repair in Jessup
Yes, and it’s a common call for us after a hard windstorm. A displaced chimney cap lets rainwater into the smoke chamber, and that water sitting near warm flue gases produces a musty, smoky smell. If the cap shifted enough to partially block the flue, you’ll also see poor draft. We’ll inspect the cap, crown, and flashing, and show you the camera footage before recommending anything. Call (336) 863-3889 to schedule a diagnostic visit.
The flue was sized for an oil burner, not a gas fireplace. Oil exhaust is hotter and needs a larger flue to draft properly. Gas runs cooler and needs a smaller flue. When the conversion happens without relining, the oversized flue can’t maintain enough draft, and combustion gases stall or push back into the room. We fix this with a correctly sized liner, typically from DuraFlex or Famco, sized to the gas appliance that’s actually there now.
It affects the permitting and code path, which can absolutely delay a repair if the technician doesn’t know which county you’re in. Parts of Jessup fall under Howard County’s building department; other parts fall under Anne Arundel. The repair itself is the same work, but the paperwork and the code details differ. We pull the right permit for your side of the line before ordering parts, which keeps the job moving. This is one of the reasons we tell Jessup homeowners to call someone who actually works this area.
At least once a year, ideally before the first fire of the season. Jessup’s humid summers and freeze-thaw winters put stress on caps, flashing, and mortar joints, so an annual inspection catches problems before the fireplace becomes a carbon monoxide risk or a water intrusion problem. If the fireplace is on an oversized, unlined flue from an oil-to-gas conversion, we’d recommend a camera inspection even sooner. A Level 2 inspection runs $149 – $225, and you’ll see the footage yourself.
Almost always, yes. Most repairs are component-level: thermocouple, pilot assembly, gas valve, warped cap, cracked crown, or a liner installed inside the existing flue. We don’t recommend masonry replacement unless the structural inspection shows bricks are spalling or the flue has collapsed. Even then, the fix is often a partial rebuild and reline, not a full tear-down. We’ll show you the camera footage and give you a written price before you commit to anything.
