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.

Gas fireplace repair in Severn typically runs $120 – $380 for common fixes like thermocouple or igniter replacement, and $800 – $2,400 when a flue liner or chase cover needs replacement.

We know Severn’s housing stock because we work in it every week: the 1960s – 80s colonials in Quarterfield Farms, the split-levels near Severn Station, and the 1990s townhome sections off Quarterfield Road. Those homes share a problem that most chimney companies never mention: gas fireplaces retrofitted into wood-burning fireboxes without proper liners. That’s our specialty here, and it’s why our Gas Fireplace Repair team runs a camera before recommending anything.
Why Alcott Chimney Sweep Is Severn’s Preferred Gas Fireplace Repair Company
Homeowners in Severn call us for two reasons: we show our work on camera, and they know exactly who’s walking through the door before the truck pulls up. Every technician who serves Severn passes a background check and identity verification as part of the Threshold Standard, and you receive the technician’s name and photo before the visit. When they arrive, they show a photo ID badge at the door. No exceptions. That matters in Severn, where so many homes are occupied by families with young kids, people working from home near Fort Meade, and older homeowners who simply want certainty about who they’re letting in.
Ruben Castellano has set one rule for every gas fireplace job in Severn: nothing gets recommended unless the homeowner sees it with their own eyes on a camera screen. No liner replacement pitch without Level 2 camera footage showing the damage. No firebox repair without photos of the rusted metal. If the camera shows the fireplace is safe, you’ll hear that too. Our Severn customers get the same written guarantee on every repair: if it fails within 365 days, the second visit is free. That’s the Done Right Promise, in writing, on every job.
Dispatch and scheduling for Severn are coordinated from our metro Baltimore office, with crews serving Severn locally throughout the week.
Our Gas Fireplace Repair Services in Severn
Gas Fireplace Level 2 Camera Inspection
The single most valuable service for Severn homes, especially those built before 1985, is a Chimney Inspection - Severn. In the 1990s, a lot of Severn homeowners converted original wood-burning fireplaces to gas by sliding in an insert and calling it done. No flue liner. No chase cover upgrade. Anne Arundel County inspectors now flag those unlined retrofits at resale. Our Level 2 camera inspection runs $189 – $289 and puts real footage in your hands: what’s inside the flue, what condition the firebox is in, and whether exhaust is venting correctly. You watch the screen while we walk you through it.

Gas Insert Flue Liner Assessment and Replacement
If your Severn home has a gas insert retrofitted into an original wood-burning firebox, there’s a strong chance it’s venting into unlined clay tile. That’s the exact scenario we find regularly in Quarterfield Farms and the older sections off WB&A Road. The clay tile corrodes over time, and exhaust that should go up the flue seeps into the chase or the wall cavity instead. Liner replacement in Severn typically runs $850 – $2,200 depending on length and access, and we install HeatShield or Famco liner systems, never box-store substitutes. We show you the camera footage before we quote it. If the liner is intact, we say so and you keep your money.

Firebox and Chase Cover Repair
Severn’s humid, Chesapeake-fed weather is hard on metal. Factory-built zero-clearance fireplaces from the 1960s – 80s are everywhere in Severn’s older colonials, and many are now 30 – 50 years past their rated service life. The thin metal fireboxes rust through, and chase covers on the roof leak, letting water drip into the unit. A rusted chase cover replacement typically runs $350 – $750 in Severn. A firebox replacement runs $1,200 – $2,400. We quote both with photos showing exactly what failed, so you’re not taking anyone’s word for it.

Igniter, Thermocouple, and Gas Valve Repair
Sometimes the problem is simpler: a dead thermocouple, a failed igniter, or a gas valve that won’t hold pressure. Those repairs run $120 – $380 in Severn, parts and labor included, with the written price in your hand before we start. We service inserts and fireplaces from Olympia Chimney and Copperfield, along with most major brands installed in Severn homes over the past three decades. If your fireplace is older and parts are discontinued, we’ll tell you that plainly and show you what the replacement options actually cost.

Trusted Brands We Service in Severn
We install and repair gas fireplace components from Copperfield, Famco, and Olympia Chimney – the same trade brands chimney professionals specify. For Severn customers, that means no waiting weeks for generic parts to ship. We keep common replacement components stocked for the fireplace models most common in Severn’s 1960s – 90s housing stock, so a thermocouple or igniter swap often happens on the first visit. When a HeatShield liner or new chase cover is ordered, we give you a firm install date and show you the manufacturer’s documentation before the work begins.
Common Gas Fireplace Repair Problems We See in Severn Homes
- Unlined retrofits from the 1990s. In Quarterfield Farms and the older subdivisions around Severn Station, gas inserts were commonly slid into original wood-burning fireboxes without an approved flue liner. Exhaust then runs through unlined clay tile, which corrodes and can vent carbon monoxide into the chase. This is where Anne Arundel County inspections catch problems during home sales, and it’s why a camera inspection matters before any repair quote.
- Rusted chase covers and fireboxes on zero-clearance units. Severn’s humidity and wet winters mean metal fireplace components fail faster here than in drier inland suburbs. A 40-year-old factory-built fireplace with a rusted chase cover will leak water into the firebox, and what starts as a “won’t light” call turns into a firebox replacement.
- Freeze-thaw spalling on older masonry. Severn sits in the Chesapeake Bay watershed, so winter moisture soaks into mortar joints on pre-1985 brick chimneys, freezes, and pops the mortar loose. If a gas insert is vented through that chimney, the structural problem needs attention before the exhaust path is safe.
- Deferred maintenance in rental stock near Fort Meade. Severn has one of Anne Arundel County’s highest concentrations of transient military and DoD contractor renters. Occupants cycle out every two to three years, and landlords often don’t track fireplace service history. The result: gas fireplaces that haven’t been inspected in three to five years, with clogged burners, failed dampers, and sometimes first- or second-degree creosote buildup from wood burned before conversion.

FAQs – Gas Fireplace Repair in Severn
If the original wood-burning fireplace was vented through unlined clay tile and the gas insert was simply slid in without a new liner, then yes, you almost certainly need a flue liner. Unlined gas retrofits exhaust into clay tile that corrodes over time, and the gap between the insert and the old flue lets carbon monoxide seep into the chase or wall cavity. The only way to know for sure is a Level 2 camera inspection, which we run for $189 – $289 in Severn, and which shows you the inside of the flue on screen. If the liner is intact, we’ll tell you that and you won’t pay for a liner you don’t need. Call (336) 863-3889 to schedule an inspection.
That sticky residue is creosote, and it’s most common in Severn homes where a wood-burning fireplace was converted to gas and the flue was never cleaned before the insert was installed. Wood creosote doesn’t disappear when you stop burning wood; it sits in the flue and can off-gas a tar-like smell, especially during humid Severn summers. In rental units near Fort Meade, we often find this because fireplaces go years without any inspection at all. A Level 2 camera inspection plus a thorough flue cleaning usually resolves the smell in one visit. Call (336) 863-3889 for a free estimate.
Yes. Severn’s humid mid-Atlantic climate, fed by the Chesapeake Bay watershed, accelerates rust on thin-metal chase covers and zero-clearance fireboxes. Freeze-thaw cycling makes it worse: moisture sits in seams and joints, freezes, expands, and opens micro-cracks that let more water in. A rusted chase cover left alone will leak into the firebox and eventually force a full replacement, which runs $1,200 – $2,400 in Severn. Replacing just the chase cover early costs $350 – $750. Call (336) 863-3889 and we’ll put a camera on it.
Ask your landlord for a Level 2 camera inspection, and request the video and written report yourself. Severn’s rental stock has some of the highest deferred-maintenance rates in Anne Arundel County because occupants cycle every two to three years and landlords lose track of service history. A fireplace that hasn’t been inspected in three to five years may have a failed damper, clogged burner, or a rusted chase cover that’s leaking into the firebox. We serve Severn renters and landlords, and we provide a written report with time-stamped photos so there’s no disagreement about what the camera showed. Call (336) 863-3889 to book an inspection.
Yes, Anne Arundel County home inspectors regularly flag gas inserts retrofitted into original wood-burning fireboxes without an approved flue liner, and it’s a recurring reason pre-listing chimney inspections have become common in Severn’s older subdivisions like Quarterfield Farms. If you’re selling a home in Severn and you know the previous owner converted the fireplace to gas sometime in the 1990s, getting a Level 2 camera inspection before listing saves you from a deal-killing surprise during the buyer’s inspection. We provide the written report and photos in the same day. Call (336) 863-3889 for a free pre-listing consultation.
