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.

Our Chimney Repair Services in Lansdowne
Mortar Repointing
The soft historic mortar in Lansdowne’s 1940s-60s brick chimneys crumbles faster than modern mixes, especially where Baltimore County’s freeze-thaw cycle hits hard. We grind out deteriorated joints to proper depth and repoint with color-matched, professional-grade mortar that bonds correctly with the original brick. On a semi-detached colonial off Hammonds Ferry Road, our tech pulled a Level 2 inspection before a Baltimore County real estate closing and found the original single-wythe flue had spalling brick faces, a cracked crown, and offset clay tile sections weeping condensation from a 1980s gas conversion - no liner ever fitted. We capped the draft issue with a correctly sized DuraFlex liner, rebuilt the crown, and repointed the joints so the sale could close. Typical repointing in Lansdowne runs $1,200-$2,400 for a standard two-flue stack.
Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is common in Lansdowne where decades of moisture penetration meet gas-conversion condensation. We remove damaged brick, source matching replacements when possible, and rebuild the affected courses with proper weep holes and drainage. Most spalling repairs in Lansdowne fall between $800 and $1,800.
Chimney Waterproofing
Lansdowne’s position in the low-lying Patapsco River valley traps ambient moisture against masonry that was never designed for it. Our waterproofing treatment uses vapor-permeable sealers from professional-grade suppliers - not the hardware-store coatings that trap water inside. We apply with proper saturation and cure time, typically $650-$1,100 for an average Lansdowne chimney. This is preventive work that pays for itself by delaying repointing or rebuilds.
Flashing Repair
Step flashing and counterflashing at the roofline fail predictably on Lansdowne’s older homes where original galvanized steel has corroded or where prior roofers caulked over the real problem. We fabricate custom flashing from copper or lead-coated copper and integrate it properly with your roofing system. Flashing repair in Lansdowne generally costs $450-$950.
Chimney Rebuilding
When deterioration exceeds what spot repair can address, we rebuild from the roofline up or perform partial rebuilds of damaged sections. We match existing brick and mortar profiles, install proper crowns with adequate overhang and drip edges, and ensure the flue is correctly sized for whatever fuel you burn. Full rebuilds in Lansdowne typically range $3,500-$7,500 depending on height, access, and liner requirements.
Tuckpointing
Tuckpointing is the decorative cousin to repointing - removing old mortar and installing new with a thin raised bead to mimic fine historic joint lines. On Lansdowne’s modest Capes and bungalows, true tuckpointing is rare; most homeowners need structural repointing instead. We’ll tell you honestly which you have and which you need. When tuckpointing is appropriate, expect $1,800-$3,200.

Trusted Brands We Service in Lansdowne
We stock professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - no builder-grade substitutes. For Lansdowne’s gas-converted flues, we keep DuraFlex and HeatShield liner components on our trucks because that call comes up so often here. That means faster turnaround and no waiting for special orders when your inspection reveals what we both suspect it might. Every part is spec’d for the application, installed to manufacturer standards, and documented in your photo report.
Common Chimney Repair Problems We See in Lansdowne Homes
- Gas conversions venting into oversized, unlined clay flues. Lansdowne’s 1940s-60s brick Capes and colonials were largely converted from oil or coal heat to gas in the 1970s-80s, leaving original oversized clay flue liners venting cooler, acidic gas exhaust - so a routine call here is more likely to need a HeatShield or DuraFlex liner install than a simple sweep. The condensation eats mortar joints from the inside, invisible until a Level 2 inspection pulls the camera.
- Freeze-thaw destruction of soft historic mortar. Baltimore County’s temperatures cross 32°F multiple times each winter, and that cycling pops the soft mortar common in Lansdowne’s post-war brick. Crowns spall. Joints erode. Water finds new paths. We see it every February.
- Efflorescence from valley moisture. The low-lying terrain near the Patapsco River keeps humidity high. White mineral staining on brick faces - efflorescence - signals water moving through the masonry, carrying salts to the surface. Homeowners often mistake it for a cleaning problem. It’s a water problem.
- Cracked crowns and deteriorated flashing on original construction. Most Lansdowne chimneys have never had their crowns replaced. The original thin concrete wash cracks, water enters, and the cycle accelerates. Same with flashing - 60-year-old galvanized steel was never meant to last forever.

FAQs - Chimney Repair in Lansdowne
Yes, almost certainly. The oversized clay flue designed for coal or oil exhaust is too large for cooler gas combustion, which causes acidic condensation that deteriorates mortar from the inside. We find this exact scenario on most Lansdowne inspections of converted homes. A correctly sized DuraFlex or HeatShield liner protects the masonry and meets modern venting standards. Call (410) 305-7884 and we’ll camera-inspect to confirm what you have.
Every year, per NFPA 211, and especially critical in Lansdowne where multiple original flues may serve both a living-room fireplace and a basement utility appliance. Each flue accumulates different combustion byproducts and deterioration patterns. Our Level 2 inspection covers every flue with photos and a separate verdict for each. Annual scheduling keeps small problems from becoming rebuilds.
Repointing removes deteriorated mortar and replaces it with new mortar that matches the original profile - this is structural repair, and it’s what most Lansdowne chimneys need. Tuckpointing is a decorative technique that creates the illusion of fine, narrow joints by adding a thin raised bead; it’s historically appropriate on ornate Victorian masonry, not on your post-war Cape or colonial. We’ll tell you honestly which applies.
That’s efflorescence - mineral salts carried to the surface by water moving through the masonry. Lansdowne’s low-lying position near the Patapsco River valley keeps ambient moisture high, and aging mortar lets more water in. The staining is a symptom. The cure is stopping the water intrusion, usually through repointing, crown repair, and waterproofing. Call (410) 305-7884 for an inspection that identifies the entry point.
A Level 2 inspection includes a visual examination of all accessible interior and exterior chimney surfaces, plus a video scan of every flue liner from top to bottom. In Lansdowne, these inspections routinely reveal gas-conversion damage inside oversized, unlined flues that neither the homeowner nor their HVAC contractor suspected. We document everything with photos, provide a plain-English verdict, and note any conditions that could delay closing. The report is yours to share with buyers, agents, or your attorney.
