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.

We’ve been working in Lansdowne long enough to know the pattern: a Cape Cod or small brick home off Hammonds Ferry Road or along Washington Boulevard, built in the 1950s for a Bethlehem Steel or GM worker, chimney still original, flue never properly lined when the furnace switched from coal to gas. The setup looks fine from the outside. It often isn’t. That’s why we start every Lansdowne liner or rebuild call with a Level 2 camera inspection - photos you can see, a plain-English verdict, and no recommendation without evidence.
Why Hearthstone Chimney Co. Is Lansdowne’s Preferred Chimney Liner & Rebuild Company
Lansdowne homeowners call us back because we document what we find and stand behind what we do. Our 90-Day Done Right Promise is in writing, no arguing - if it’s not right, we come back.

Dispatch and scheduling are coordinated from our Baltimore office, but our crews serve Lansdowne locally and know the area’s chimneys: the Patapsco valley humidity, the freeze-thaw cycle that attacks mortar, the coal-era flues that were never meant for gas.

Our Chimney Liner & Rebuild Services in Lansdowne
Stainless Steel Liner Installation
A stainless steel liner is the right fix for most Lansdowne homes with deteriorated clay tile or no liner at all. We size the liner to the appliance, not the chimney - critical in Lansdowne, where a flue built for coal is often three times too large for a modern gas furnace. An oversized flue causes poor draft, condensation, and accelerated mortar damage. We install DuraFlex and Olympia Chimney stainless systems, cut to length on site for the shorter runs typical of Lansdowne’s one-and-a-half-story Cape Cods. Most installations run $2,200-$3,800 and are completed in a single day.

Flexible Liner Installation
Some Lansdowne chimneys have offsets or bends that rigid pipe won’t navigate - common in homes where the flue was modified during a basement conversion or where the chimney was built around a structural post. A flexible liner, properly insulated, threads through these obstacles without breaking the flue wall. We use professional-grade flexible systems from DuraFlex, not the thin-wall products sold at hardware stores. Flexible installations in Lansdowne typically cost $2,600-$4,200, depending on length and whether the existing clay tile must be removed first.

Liner Replacement
When a liner has failed completely - cracked clay tile, collapsed sections, or corrosion from years of condensation - replacement is the only safe option. In Lansdowne, we see this most often in chimneys that vent both a bricked-up first-floor fireplace and a basement furnace through the same damaged flue. That shared-flue configuration is a carbon monoxide risk we won’t patch over. Liner replacement includes full camera documentation, proper sizing, and a new cap and connector. Most Lansdowne liner replacements fall between $2,800-$4,500.

Partial Chimney Rebuild
When the liner has failed because the chimney itself is failing - spalling brick, deteriorated mortar joints, a cracked crown letting water straight to the flue - a liner alone won’t solve it. Partial rebuilds address the upper section of the stack, the crown, and the flashing, preserving the sound brick below. In Lansdowne’s Patapsco valley climate, freeze-thaw damage concentrates at the crown and shoulders. We rebuild with matching brick where possible and always install a proper concrete crown with drip edge. Partial rebuilds in Lansdowne typically run $3,200-$6,500.

Common Chimney Liner & Rebuild Problems We See in Lansdowne Homes
- Unlined or cracked clay-tile flues from the coal era. Most Lansdowne chimneys were built for coal heat and never received a proper liner when furnaces converted to oil or gas. The original clay tile, if present at all, is now 60-80 years old and often cracked from thermal shock. Carbon monoxide can seep through gaps into living spaces - a hazard camera inspection reveals immediately.
- Shared flues between bricked-up fireplaces and basement furnaces. A distinctive Lansdowne pattern: the first-floor fireplace was bricked up decades ago, but the same flue now vents a gas furnace below. Two different eras of use, one undersized or unlined passage. Local sweeps flag this routinely; homeowners are usually unaware until the camera shows them.
- Flue dimensions wrong for modern appliances. Coal combustion required large, hot flues. Today’s low-temperature gas appliances need smaller, precisely sized passages. An oversized flue in a Lansdowne home leads to sluggish draft, condensation running down the walls, and mortar deterioration from the inside out. A liner sized to the appliance fixes it.
- Freeze-thaw damage from Patapsco valley moisture. Lansdowne sits in a humidity corridor where winter moisture wicks into aging brick, freezes, and spalls the face off. Crown cracks and failed flashing follow, letting water reach the flue liner. We repair the source of water entry, not just the symptom.

FAQs - Chimney Liner & Rebuild in Lansdowne
Yes, and it’s one of the most common hazards we find in Lansdowne. The original coal-era chimney was built to serve the first-floor fireplace; when heat converted to oil or gas, the furnace was tied into the same flue without resizing or lining. A Level 2 camera inspection will show you exactly what’s inside. Call (410) 849-6273 and we’ll document it - estimates are free.
You need a camera inspection to know for certain. Cleaning removes creosote and debris; it does not fix cracked clay tile, an unlined flue, or improper sizing for your appliance. In Lansdowne’s older housing stock, we find liner problems in roughly two out of three chimneys built before 1970. We’ll show you the footage and explain what you’re seeing. No recommendation without evidence you can see yourself.
Lansdowne sits in the Patapsco River valley, where winter humidity is higher and freeze-thaw cycling more pronounced than in drier inland areas. Moisture wicks into 60-80-year-old brick, freezes, and pushes off the face. The crown and flashing fail next, and water reaches the flue. We repair the water entry point as part of any liner or rebuild job - otherwise the new work fails too.
We install DuraFlex, Olympia Chimney, and Famco systems - professional-grade products, not hardware-store substitutes. We stock the common diameters for Lansdowne’s gas furnaces and water heaters on our trucks, so most jobs don’t wait for parts. Every installation carries our 90-Day Done Right Promise in writing.
Yes. In Lansdowne, the bigger risk is often the gas furnace or water heater venting through an unlined or deteriorated flue - not the fireplace. Carbon monoxide has no smell. An annual Level 2 inspection with a camera finds liner cracks, mortar gaps, and shared-flue hazards before they become emergencies. Call (410) 849-6273 to schedule; estimates are free.
