Fireplace Installation & Service in Maryland
Gas inserts (vented and ventless), wood-burning inserts, pellet stoves, EPA-certified appliances, wood-to-gas conversions, glass door installs, and hearth refresh.

About Our Fireplaces Service
A fireplace is more than a heat source — it is the visual and emotional center of the room it occupies. Eagle Chimney Service designs, installs, and services the full range of residential fireplaces and stoves across Maryland and DC: vented gas inserts that retain the look of a wood fire with thermostatic convenience, ventless gas appliances for spaces where venting is impossible, EPA-certified wood inserts that turn an open fireplace into a 70-percent-efficient heater, pellet stoves that burn renewable biomass with automated feeders, and traditional wood-burning open fireplaces refreshed with new doors, dampers, and refractory panels.
The most common installation we perform is a gas insert. A gas insert slides into an existing masonry fireplace, vents through a stainless steel co-axial liner system up the existing chimney, and converts an inefficient open fireplace into a 70- to 85-percent-efficient heat source operated by remote or wall thermostat. We size the liner to manufacturer specifications based on Btu input, install the insert per IRC and NFPA 211, run gas line where needed (coordinated with licensed gas-fitters), and commission the appliance with a complete safety check including manometer pressure test, draft verification, and CO test. Vermont Castings, Lopi, Jotul, Regency, Napoleon, Heat-N-Glo, and Mendota are among the brands we install regularly.
Wood-burning inserts deliver the experience of a real wood fire with dramatically improved efficiency over an open masonry fireplace. We install EPA Phase 2 and Phase 3 certified inserts with proper insulated stainless liners, install required combustible clearances, and verify the existing chimney can support the insert's vent requirements. For homeowners committed to wood heat, pellet stoves and freestanding wood stoves remain popular — we install both with the venting, hearth pad, and clearance requirements specified by the manufacturer and code.
Conversions are a frequent request. Converting a wood-burning fireplace to gas requires a properly sized liner (often dramatically smaller than the existing wood chimney), a sealed firebox or insert, a gas supply line, and a damper modification or block-off to prevent the open damper from killing efficiency. We handle the entire conversion as a single project — Level 2 chimney inspection, liner installation, appliance install, gas line coordination, and final commissioning. Glass door installs on existing open fireplaces, refractory panel replacement, gas log set installations with safety pilot kits, and hearth refresh complete our fireplace service offering. Every installation is registered with the manufacturer for full warranty coverage.

Frequently Asked Questions
Quick answers to common chimney questions.
NFPA 211 and the International Residential Code require a code-compliant liner for every active chimney. Common triggers for relining are: cracked or missing clay tile liner (visible on Level 2 video scan), wood-to-gas conversion (existing wood flue is oversized for new gas appliance), post-chimney-fire thermal damage, and any chimney with no liner at all (common pre-1940).
Stainless steel liners (UL-listed 316Ti for wood/oil, 304 for gas) are the most common solution and the gold standard for most relining jobs. HeatShield is a ceramic cerfractory material that bonds to existing intact clay tile and rebuilds damaged areas — right where the tile is structurally sound but joints have failed. Supaflu is a cast-in-place liner for chimneys with unusual geometry (multiple offsets, oversized flues, odd shapes).
A typical stainless steel reline takes one day. HeatShield Joint Repair takes one day; full Resurfacing System takes 2-3 days including cure time. Supaflu cast-in-place takes 2-4 days. We schedule based on weather (concrete cure considerations) and your appliance availability.
Yes — this is one of our most common installations. Full conversion includes NFPA 211 Level 2 inspection, properly sized stainless steel liner install, direct-vent gas appliance install, gas-line coordination with a licensed gas-fitter, and commissioning with manometer pressure test and CO verification. We install Vermont Castings, Lopi, Jotul, Quadra-Fire, Regency, Napoleon, Heat-N-Glo, and other premium brands.
Yes. We install EPA Phase 2 and Phase 3 certified wood-burning inserts, freestanding wood stoves with Class A chimneys, and pellet stoves with vertical and horizontal vent runs. All installations include code-compliant clearances per NFPA 211 and manufacturer specifications, plus hearth pad installation where required.
Yes. A throat damper — even one that looks closed — typically leaks 8-15 percent of HVAC energy because warped, rusted, or imperfect seal allows continuous air exchange up the chimney. A top-sealing damper at the crown uses a silicone rubber gasket to create an airtight seal, eliminating the loss. On a typical Maryland home, the upgrade pays for itself in 1-3 winters.
Yes, where local code permits. Ventless gas appliances have strict CO and ODS (Oxygen Depletion Sensor) requirements and combustion-air calculations. We install only models with current AGA/CSA listing and only where applicable code allows ventless operation. We do not recommend ventless installation in bedrooms or bathrooms regardless of local code.
Yes. We register every manufacturer warranty (cap, liner, insert, damper, waterproofing) in your name and email you the registration confirmation before we leave the property. This is included in every install — you do not have to chase paperwork.
