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.

Why Hearthstone Chimney Co. Is Greenbelt’s Preferred Chimney Liner & Rebuild Company
We’ve been answering calls with a live person for over 42 years, and that steady presence matters in a city like Greenbelt where homeowners stay put for decades. Our technicians are background-checked, uniformed, and trained to document every inspection with photos you can see and a plain-English verdict - no jargon, no pressure.
Greenbelt’s housing stock demands this level of documentation.

Our Chimney Liner & Rebuild Services in Greenbelt
Stainless Steel Liner Installation
For Greenbelt’s 1950s-70s ranchers and colonials in Greenbelt East, a stainless steel liner from Olympia Chimney or Gelco is often the right fix when the original clay tile has cracked from decades of freeze-thaw cycling. Prince George’s County winters deliver genuine freeze-thaw stress, and once a clay tile liner spalls or separates, exhaust gases can leak into the chimney cavity. We measure your flue on-site, cut the stainless steel to length, and install it with proper insulation and a new top plate - usually in one day. The homeowner sees camera footage of the damage before we start and the completed installation after.
Flexible Liner Installation
Flexible liners solve the offset flues and tight chimney chases common in Greenbelt’s older homes. In Old Greenbelt’s GHI row houses, the original 1937 construction often includes bends or narrow passages where rigid stainless steel won’t pass. Our flexible DuraFlex liners navigate these obstacles while maintaining proper draft. This matters especially in Greenbelt’s humid subtropical climate, where summer moisture accelerates corrosion in unlined or damaged flues. We size the flexible liner to your appliance - wood stove, gas insert, or furnace - and back it with the manufacturer’s warranty plus our own 90-Day Done Right Promise.
Liner Replacement
Liner replacement is our most common call in Greenbelt, and for good reason. The original clay tile liners in Old Greenbelt’s GHI units are approaching 90 years old. Clay tile shrinks, cracks, and shifts; mortar between tiles crumbles. We’ve replaced liners on homes along Ridge Road and throughout the historic district where the flue was so deteriorated that a Level-2 camera inspection revealed gaps you could slide a pencil through. We don’t recommend replacement based on age alone. We show you the camera footage, explain the condition, and quote the job before any work begins. If the liner can be repaired with HeatShield cerfractory sealant instead, we’ll tell you that too.
Partial Chimney Rebuild
When the liner has failed and the surrounding masonry is compromised, a partial rebuild addresses the firebox, smoke chamber, or upper chimney stack without tearing down the entire structure. In Greenbelt’s GHI row houses, this requires particular care: the party-wall construction means one exterior stack serves two units, and any rebuild must preserve or restore the clay tile divider between flue channels. We’ve rebuilt chimney crowns and upper courses on Greenbelt homes where freeze-thaw spalling had exposed the liner to direct water intrusion. Our crews work with Famco and Copperfield components, matched to the existing masonry, and we coordinate with GHI maintenance when the shared stack requires association notification.

Common Chimney Liner & Rebuild Problems We See in Greenbelt Homes
- Cracked clay tile dividers in GHI party-wall chimneys. In Old Greenbelt’s cooperative row houses, a single exterior stack contains two flue channels separated by thin clay tile. Our camera inspections regularly find hairline cracks in this divider, which allows exhaust and creosote to migrate between units. Any liner or rebuild work must address this divider specifically, not just the flue opening you can see from the roof.
- Third-degree creosote glazing in original 1937 flues. The narrow, unlined or original clay tile flues in Greenbelt’s oldest homes trap creosote that standard brushes cannot remove. We’ve encountered tar glaze so thick it reduces the flue diameter by a third. Without a camera inspection, this hazard stays hidden until it becomes a chimney fire risk.
- Freeze-thaw spalling in 90-year-old mortar joints. Prince George’s County winters produce repeated freeze-thaw cycles that break down the original 1930s mortar in Old Greenbelt chimneys. Spalling mortar exposes liner tiles to direct moisture, accelerating deterioration. Annual inspection catches this early; waiting until chunks of masonry fall off means the rebuild scope grows.
- Appliances vented into chimneys never designed for them. Greenbelt East’s mid-century homes often have furnace or water heater retrofits venting into old fireplace flues. The original liner sizing and material may be wrong for the appliance type, creating draft problems and condensation damage. We evaluate the entire system, not just the visible flue top.

Costs in Greenbelt run comparable to College Park and Beltsville, with variation driven by flue accessibility and whether the chimney is a single-family stack or a GHI party-wall unit requiring association coordination. The highest-cost factor we see is deferred maintenance: a liner that could have been repaired with HeatShield at $1,500 becomes a full replacement at $3,500 after three more years of freeze-thaw damage. We offer $50 off any repair over $250, free second opinions on written estimates from other companies, and a permanent 5% senior and veteran discount.

FAQs - Chimney Liner & Rebuild in Greenbelt
Yes, for most liner and rebuild work on GHI cooperative properties, the association’s maintenance office must authorize the repair because the chimney stack is a shared structural element. We coordinate this paperwork directly with GHI once we’ve completed our camera inspection and prepared our recommendation. Call (301) 479-9806 and we’ll walk you through the specific approval steps for your unit.
We run a high-resolution camera down both flue channels and specifically inspect the shared divider wall from each side. A crack in the divider is invisible from the roof opening but clearly visible on camera as a gap or displacement in the clay tile. In Old Greenbelt, we were called to a 1937 GHI row house on Ridge Road where a homeowner reported a faint smoke smell in the upstairs bedroom whenever the neighbor’s fireplace was burning. Our crew ran a camera down the flue and found a hairline crack in the clay tile divider between the two party-wall channels, plus first-degree creosote coating both sides. We documented the crack with photos, coordinated the repair through GHI’s maintenance office, and installed a HeatShield liner in the affected channel with a new chimney cap to stop water intrusion.
It depends on the condition of the tiles and the mortar joints between them, which we determine with a Level-2 camera inspection. If the tiles are intact with minor mortar loss, HeatShield cerfractory sealant can restore a smooth, insulated flue surface without full replacement. If tiles are cracked, shifted, or missing, replacement is the safer and longer-lasting option. We’ve done both in Greenbelt’s GHI properties, and we recommend based on what the camera shows - not on age alone. Call (301) 479-9806 for a free inspection and we’ll show you exactly what your flue looks like inside.
A smoke smell migrating between units in a GHI row house almost always indicates a breach in the clay tile divider between the two flue channels within the shared chimney stack. Exhaust gases and creosote odors pass through cracks or missing sections of this divider, then enter the neighboring flue and leak into the living space through any opening in the fireplace or surrounding structure. This is a cross-contamination issue unique to party-wall construction, and it requires camera inspection of both flues plus repair or relining of the affected channel. We document the breach with photos and coordinate the repair through GHI.
Yes, especially in Greenbelt’s humid subtropical climate with freeze-thaw winters. Even gas and oil appliances produce acidic condensation that deteriorates clay tile and mortar. In a 90-year-old chimney, annual inspection catches spalling mortar, cracked tiles, and water intrusion before they require full rebuild. For GHI properties, the inspection also verifies the integrity of the party-wall divider, which affects both units regardless of which one burns fuel. We recommend annual Level-2 inspections for all pre-1950 Greenbelt chimneys, and we include photo documentation with every report. Call (301) 479-9806 to schedule - estimates are free.
