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.
Fast, Reliable Chimney Repair Across Lansdowne
Chimney repair in Lansdowne typically runs $350 – $2,800 depending on what’s actually wrong, and the honest answer is that a proper diagnosis requires a camera, not a guess. We’ve spent two decades working on the 1920s – 1940s brick bungalows and Tudor-style homes that fill Lansdowne’s streets, and we know exactly how those chimneys fail. Before any work starts, you get a written price. Before any repair is recommended, you see photo evidence of the problem. That’s how Flint Chimney Sweep operates under The Garrison Standard, and it’s why Lansdowne homeowners call us at (830) 251-4560 when something looks wrong up top.
Why Flint Chimney Sweep Is Lansdowne’s Preferred Chimney Repair Company
We’ve been at this since 2002 as part of the Garrison Partners family, and the reason Lansdowne homeowners keep calling us back is simple: everything goes in writing. The price, the scope, the guarantee. Hank Delano, who leads our operation, built the business on a code that doesn’t allow vague estimates or surprise add-ons. When our background-checked, uniformed tech pulls up to a house off Washington Boulevard or near the elementary school, you already know exactly who’s walking through the door and what the job will cost.
Lansdowne is tight-knit. Word travels when a contractor leaves a mess or won’t answer a callback. Our reputation here is built on the 365-Day Done Right Promise: every repair carries a written guarantee valid for one full year, and if a covered repair fails in that window, we return at no charge. No argument, no second invoice. We also answer the phone with a live person 24/7. That matters when you’re staring at a water stain spreading across the ceiling on a rainy Sunday night in November.
Our crews know Lansdowne’s housing stock intimately. We’ve run camera inspections on bungalows along Railway Avenue, Tudors near the library, brick fronts on both sides of the 21227 ZIP. That local familiarity means we arrive already knowing what we’re probably looking at, which is faster for you and more accurate.
Chimney Masonry Repair in Lansdowne
Chimney Masonry Repair in Lansdowne is frequently about one thing: soft Baltimore-area brick that has spalled after decades of freeze-thaw cycling on the south and west exposures of the stack. Those 1920s – 1940s era homes were built with brick that was never meant to absorb forty or fifty Maryland winters. When the face of a brick pops off and crumbles, that’s spalling, and it’s not cosmetic. Water gets into those exposed pores, freezes, expands, and the damage accelerates year over year. Left alone, a homeowner who thinks they need a small cap repair ends up looking at a partial or full chimney rebuild. Masonry repair in Lansdowne typically runs $450 – $1,800 depending on how much of the stack needs Tuckpointing, repointing, or brick replacement.
Mortar Repointing and Tuckpointing Work
Repointing is removing deteriorated mortar joints and packing fresh mortar into the gaps. Tuckpointing is the finer version, where we include a contrasting thin line to mimic the original joint on older brickwork. On a 1930s Lansdowne bungalow, the original mortar was lime-based and softer than modern mixes. We match it properly so the joints can flex and breathe the way the original masons intended.
Flashing and Waterproofing Repairs
Flashing repair is the single most common masonry-adjacent fix we do in Lansdowne. Galvanized flashing rusts through after twenty or thirty years, and the metal bends and pulls away from the brick line. When that happens, water tracks down the side of the chimney and into the house. We install Copperfield or Olympia Chimney flashing and apply a breathable waterproofing membrane to the exposed brick faces where appropriate. A straightforward flashing replacement in Lansdowne generally falls between $300 and $700.
Chimney Cap Installation in Lansdowne
Chimney Cap Installation in Lansdowne solves three problems at once: rainwater entering the flue, animals nesting inside the stack, and backdraft that pulls smoke into the house on windy days. A properly fitted stainless cap, usually from Famco or Olympia Chimney, lasts decades and pays for itself the first time it keeps a Baltimore County rainstorm out of your firebox. Cap installation in Lansdowne runs $250 – $500 depending on the flue size and whether the crown needs repair first. The cap itself is the cheap part. The crown underneath is often where Lansdowne homeowners find the larger issue.
Crown Sealing and Replacement
The crown is the concrete or mortar slab that bridges the gap between the brick stack and the flue liner. Cracking in the crown is how water gets behind the brick, into the flue liner joints, and eventually into your ceilings. We see cracked crowns on at least half of the 1930s-era chimneys we inspect in Lansdowne. A crown repair with proper overhang and a flexible sealant runs $350 – $800 depending on whether we’re sealing or rebuilding the slab entirely.
Stainless Multi-Flue Cap Sizing
When a Lansdowne home has two flues, like one for a furnace and one for a wood-burning fireplace, a single multi-flue cap makes better sense. We size it to the full crown footprint and anchor it securely. This keeps precipitation out of both flues and solves the occasional problem where a single-flue cap allows water to pool on one side of the crown.
Trusted Brands We Service in Lansdowne
We don’t install bargain parts that fail in five years. Our repair work in Lansdowne involves professional-grade materials from brands homeowners can verify independently. We keep an inventory of stainless steel components, flue liners, caps, and masonry products from Copperfield, DuraFlex, and Famco stocked for the common configurations we see on Lansdowne’s pre-war housing stock. That local parts availability means when we find a problem during an inspection, we can often complete the repair the same week instead of waiting on a special order from somewhere out of state. We specify the material by the job, not by which product line earns us the highest margin. That’s The Garrison Code in action.
Common Chimney Repair Problems We See in Lansdowne Homes
Lansdowne’s chimneys fail in predictable ways, and being familiar with those patterns means we find problems faster and recommend repairs at the right time. Here’s what we regularly find, from the ground up:
- Soft brick spalling on south and west facings. Those faces take the brunt of sun and storm exposure. A homeowner on Scottdale Road may not notice the deterioration until pieces of brick are scattered on the roof or in the gutter. By the time it’s visible from the ground, the masonry behind it is often compromised.
- Second-degree creosote in the smoke chamber. A few seasons of slow-burning fires in a 1930s bungalow builds a hard, flaky layer that a standard brush can’t fully remove. We see this on nearly every wood-burning chimney in Lansdowne that hasn’t been professionally cleaned in two or more years. It needs chemical treatment or mechanical removal, not just a sweep pass.
- Cracked crowns and rusted flashing. Lansdowne’s neighborhoods are full of chimneys where the crown was poured without a proper overhang edge, and the flashing was installed with roofing tar instead of proper ice-and-water membrane. Water wicks into the flue liner joints and shows up as spalling brick, not an obvious leak. Homeowners call about a damp wall and don’t realize the path started at the top of the chimney.
- Flue liner deterioration in unlined or terra cotta flues. Many 1920s Lansdowne homes were built with a simple terra cotta liner, which splits under repeated heating and cooling cycles. The cracks let heat and carbon monoxide into the wall cavity. A camera inspection is the only way to confirm this, and we always provide the video or photos before recommending a stainless reliner.
On a recent call off Scottdale Road, our tech ran a Level 2 inspection on a 1930s brick bungalow and found the firebox mortar joints crumbling while second-degree creosote flaked off the smoke chamber walls. We installed a HeatShield flue liner resurfacing and a new stainless chimney cap, then handed the homeowner a photo report showing before and after images of every joint we touched. That’s the standard. Every Lansdowne job gets that same documentation.
Pricing for Chimney Repair in Lansdowne, MD
We don’t make Lansdowne homeowners call just to learn the ballpark. Here’s what repairs actually cost here, based on the work we do across Lansdowne’s 1920s – 1940s housing stock:
- Chimney cap installation (stainless, single-flue): $250 – $500
- Crown repair or seal: $350 – $800
- Mortar repointing / tuckpointing (partial chimney): $450 – $1,100
- Flashing repair or replacement: $300 – $700
- Chimney waterproofing treatment: $200 – $450
- Partial or full masonry rebuild: $1,500 – $2,800
- HeatShield flue liner resurfacing: Starts at $1,100 depending on flue height
The two variables are access and the condition of the underlying masonry. A chimney on a tight lot with a steep roof pitch takes longer to stage safely. A chimney where spalling has progressed behind the cap or crown costs more because we’re rebuilding structure, not just sealing a surface. Free estimates are real. We come out, put eyes and a camera on the chimney, and hand you a written price. Call (830) 251-4560.

FAQs About Chimney Repair in Lansdowne
A wood-burning flue in Lansdowne needs cleaning once per year if it’s used regularly from October through March, and likely once every two years if it’s used occasionally. The reason is creosote accumulation in the smoke chamber of older bungalows, where a shallow throat and tight turn catch more soot than a modern firebox would. We recommend an inspection combined with the sweep so you see the inside of the flue and know whether anything has changed since last year. Call (830) 251-4560 to schedule, and we’ll give you a written price before any work starts.
A Level 2 inspection adds a video camera scan of the entire flue interior, from firebox to cap, to the standard visual check of all accessible parts. For a Lansdowne home built in the 1920s or 1930s, this camera pass is the only way to confirm the condition of the terra cotta liner, the smoke chamber, and the interior masonry. We provide a photo report after every inspection, so you can see exactly what the camera saw and why we’re recommending anything. The inspection itself is priced up front like every Flint service.
No. Third-degree creosote is a hard, tar-like deposit that has been baked by repeated chimney temperatures and cannot be removed with a standard wire brush. In a Lansdowne flue with decades of use, this material usually requires chemical breakdown treatments or mechanical removal with specialized rotary tools. Attempting to burn it off is dangerous. We’ll show you the camera footage of exactly what’s in the flue before recommending a removal method.
Most of the 1920s – 1940s bungalows in Lansdowne were built with unlined or terra cotta lined flues, and a significant number of those terra cotta liners have cracked after ninety years of heating cycles. A cracked liner is a legitimate safety issue because it can allow heat and carbon monoxide into the wall cavity. We recommend a stainless steel liner from DuraFlex or a HeatShield resurfacing depending on the flue shape and condition. Either way, you’ll see the defect on camera before we ask you to spend a dollar.
Only if the water problem starts at the top of the flue, which is common but not universal. Water issues can also originate from a cracked crown, worn flashing at the roofline, or spalling brick that’s soaking water into the structure from the side. We’ll trace the actual path, which is why our inspections include the full stack and not just a glance at the top. If the cap is the fix, expect to pay $250 – $500 for a stainless unit, and we’ll show you the write-up before we install anything.
