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 Chimney Liner & Rebuild Across Lansdowne
Most Lansdowne chimneys were built to vent coal smoke, not today’s high-efficiency gas furnaces. That mismatch is the root cause of nearly every liner failure we find between Hammonds Ferry Road and the Patapsco River valley. If your 1950s Cape Cod or brick bungalow still has its original clay tile liner, odds are it’s spalling, cracked, or partially collapsed right now. Call (443) 332-7798 and we’ll put a camera up there before anyone recommends spending a dime.

Our Chimney Liner & Rebuild Services in Lansdowne
Our Chimney Liner & Rebuild team handles the full range of flue work, but in Lansdowne three jobs dominate: stainless steel liners for gas conversions, liner replacements for failed clay tiles, and full rebuilds for chimneys that have gone too far. Here’s how each works in this neighborhood’s older homes.
Stainless Steel Liner
When we run a Level 2 camera inspection on a Lansdowne chimney and find cracked clay tiles, the fix is usually a properly sized stainless steel liner. This is not a one-size-fits-all job. A liner for a gas furnace needs different diameter calculations than one for a wood stove. We install DuraFlex liners sized exactly to the appliance’s BTU output and venting requirements, so the flue drafts correctly and condensation doesn’t eat the new liner the way it ate the old clay.
Flexible Liner
Older Lansdowne flues are rarely straight. Most of the brick chimneys on 1940s and 1950s bungalows have offsets, corbels, or subtle shifts from decades of settling. A rigid liner won’t navigate those turns without tearing out brick. We stock Famco and Copperfield flexible liners that snake through existing flue geometry, avoiding demolition wherever possible. When Wendell recommends a flexible liner, he shows you the camera footage first so you can see why it’s necessary.
Liner Replacement
Some Lansdowne homeowners think a stainless liner was installed years ago and assume it’s fine. But old aluminum liners, improperly sized liners, and liners installed without insulation all fail. If your furnace has been venting into an uninsulated liner, condensation on the liner’s exterior corrodes it from the outside while flue gas attacks it from within. We pull the old liner, document everything on camera, and install a replacement rated for the current appliance. If the previous liner was installed wrong, you’ll see the evidence yourself.
Partial Rebuild
Chimney crowns on Lansdowne’s older homes are typically poured concrete slabs that crack within a decade, letting water into the brick and mortar below. The top five to fifteen courses of brick absorb that water, freeze and thaw through Patapsco River valley winters, and start spalling. If the damage is confined to the upper section, a partial rebuild makes sense: we tear down to stable brick, relay the courses with proper mortar, pour a new crown with a drip edge, and seal everything with Gelco. But we don’t quote a partial rebuild until the camera confirms the lower flue is sound. Recommending a partial when a full rebuild is needed just kicks the problem down the road, and we won’t do that to a Lansdowne neighbor.

Trusted Brands We Service in Lansdowne
We install and service liners and rebuild components from DuraFlex, HeatShield, Famco, and Copperfield. These are the brands we trust because they’ve held up year after year in Baltimore County’s damp climate. Since we stock common liner components and crown materials locally, most Lansdowne liner jobs don’t wait on shipping from a distributor. When your chimney is open and exposed, downtime matters. We keep the parts on hand to finish the job in one visit whenever the camera inspection confirms what’s needed.
Common Chimney Liner & Rebuild Problems We See in Lansdowne Homes
- Spalling clay tiles from freeze-thaw cycles. Lansdowne’s position at the edge of the Patapsco River valley means persistent humidity and fog. Moisture seeps into aging clay flue tiles, freezes in winter, and fractures the tile from within. We regularly pull chunks of clay tile off smoke shelves on Hollins Ferry Road, Oak Road, and the streets off Washington Avenue.
- High-efficiency gas appliances venting into oversized coal-era flues. A gas furnace or water heater produces far less exhaust heat than the coal furnaces these chimneys were built for. That cooler exhaust doesn’t draft properly in an oversized flue. It condenses inside the chimney, and the acidic condensate dissolves mortar and brick from the inside out.
- Collapsed flue sections hidden behind rooflines. A chimney can look perfectly fine from the ground while the clay liner has collapsed ten feet above the firebox. Carbon monoxide and flue gases then move through wall cavities instead of out the top. The only way to find it is a Level 2 camera inspection, which we include before any liner recommendation in Lansdowne.
- Crown and wash failures letting water into the chimney system. The original crowns on 1950s Lansdowne bungalows are often just a thin mortar wash sloped toward the flue tile rather than away from it. That’s a design flaw by today’s standards. Water pools, saturates the brick, and accelerates every other failure mode on this list.
Pricing for Chimney Liner & Rebuild in Lansdowne, MD
A full stainless steel liner installation in Lansdowne typically runs $3,200 to $5,800 depending on flue height, liner diameter, and whether insulation is required. Liner replacement on a single-story bungalow with a straight flue can come in around $2,400 to $3,500. Partial rebuilds run $1,800 to $4,000 depending on how many courses of brick need relaying and whether a new crown is poured. A full chimney rebuild from the roofline up on a two-story Lansdowne Cape Cod generally lands between $6,000 and $11,000. We give the exact number in writing before any tool comes off the truck, and the $40-off-any-repair-over-$200 offer applies to liner and rebuild work. If you’ve already got a written estimate from another company, we’ll give you a free second opinion, and there’s no trip charge for calls inside the county. Seniors and veterans always get 10% off.
Here’s a quick reference for what affects the final number in Lansdowne:
- Flue height: A two-story chimney costs more to line than a single-story bungalow. More liner, more labor, more scaffolding.
- Liner diameter and insulation: Gas appliances need smaller liners than wood stoves. Insulated liners add material cost but prevent condensation corrosion.
- Access: Some Lansdowne rowhouse clusters have tight setbacks and shared chimneys, which complicate ladder placement and add time.
- Condition of surrounding brick: If a liner failure has also damaged the crown or upper brick courses, the total job includes partial rebuild work.

FAQs - Chimney Liner & Rebuild in Lansdowne
You can’t know for certain without a Level 2 camera inspection, which we run before any liner recommendation in Lansdowne. Homes built between 1945 and 1965 in this area almost always shipped with clay tile liners, and those liners are now 60 to 80 years old. The camera shows us exactly what’s happening inside: cracking, spalling, collapse, or intact tile. You watch the footage on site and get a plain-English verdict before a single recommendation is made. Call (443) 332-7798 to schedule an inspection, and remember there’s no trip charge inside the county.
Because your chimney was built for coal or early oil combustion, not the low-temperature exhaust of a high-efficiency gas furnace. Older flues were oversized for the fuel they burned, which created enough draft to move exhaust out. A modern gas appliance produces cooler exhaust in lower volume. That exhaust doesn’t draft properly in an oversized flue and instead condenses inside the chimney, creating acidic moisture that dissolves mortar and brick. In Lansdowne, where most homes still vent gas appliances through original clay tile flues, this is the single most common code violation we document. A properly sized stainless liner fixes it. Call (443) 332-7798 and we’ll show you the camera evidence from your own chimney before recommending anything.
If the damage is confined to the upper brick courses and crown, a partial rebuild is usually all that’s needed. We tear down to stable brick, relay the courses, and pour a new crown. But we won’t commit to a partial rebuild until the camera confirms the lower flue is sound. If the flue liner has collapsed lower in the stack, a partial rebuild would leave a dangerous condition in place. The camera tells us what the roofline can’t. Call (443) 332-7798 for a free estimate and we’ll inspect before we quote.
Third-degree creosote is a hardened, glossy glaze that forms when wood burns at low temperatures and creosote condenses on the flue walls. In an old Lansdowne chimney with a failing clay liner, that glaze seals the surface and can’t be removed with standard brushing. A new liner doesn’t remove third-degree creosote; the old flue must be cleaned or the glazed tiles removed before a liner is installed. We’ll show you the footage so you can see the exact condition, and we only recommend a liner rebuild if the existing flue can’t be restored. Call (443) 332-7798 and we’ll schedule the inspection.
Once a year, burn or no burn. Chimneys break in the off-season too. For an older Lansdowne home with a 60-plus-year-old chimney, we recommend a Level 1 inspection every year and a Level 2 camera inspection whenever there’s a change in appliance, a chimney fire, a real estate transaction, or visible masonry damage. The Level 2 is what catches the collapsed clay liner sections, the oversized-flue condensation damage, and the hidden crown failures that Level 1 can’t see. Call (443) 332-7798 and we’ll get you on the schedule before burning season.
Camera First. No Upsell. That’s the Standard.
We relined a 1952 brick bungalow on Hollins Ferry Road after our Level 2 camera showed a 20-foot run of original clay tile with horizontal cracks at every mortar joint and a collapsed section three feet above the smoke chamber. The homeowner had been venting a high-efficiency gas furnace into that oversized flue, and acidic condensate had eaten the mortar so badly that spalled clay shards were piling up on the smoke shelf. We installed a DuraFlex stainless steel liner properly sized for the gas appliance, sealed the crown with Gelco, and capped it with a Copperfield cap. That was the first time that chimney had been safe since coal was phased out.
That’s how we work in every Lansdowne home. The camera footage and a plain-English verdict, every time, no exceptions. If the chimney doesn’t need work, we’ll tell you that too and hand you the inspection report. If it does need work, you’ll see exactly why, and the price stays the same from the phone call to the invoice.
Your flue doesn’t care how the fire looks. It cares how it breathes. If your Lansdowne chimney was built for coal and is now venting a gas furnace, it’s worth having us take a look. Call (443) 332-7798 for a free estimate and a straight answer from Wendell and his crew.
