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 Repair Across Lansdale
Chimney repair in Lansdale typically runs $850-$4,200 depending on scope, and most jobs start with a Level 2 camera inspection that gives you photos, a written scope, and a fixed price before any work begins. Our crews serve Lansdale from our Philadelphia office, and we book most inspections within a few business days. Call (484) 806-9176 to schedule.
We’ve worked the borough’s housing stock long enough to know that Lansdale chimney problems rarely follow the suburban pattern. The dense blocks near Main Street and the SEPTA Lansdale station hold Victorian-era row houses and foursquares with full brick masonry chimneys, many built for coal-burning systems and later converted to oil or gas. Those conversions left behind oversized, often unlined flues that don’t match modern appliances, and shared stacks where one neighbor’s dead flue can quietly destroy the other’s active one. That’s not a theory for us. Our Chimney Repair team has documented it on inspection reports across the borough since 2009.
Why Level Two Chimney Chesterbrook Is Lansdale’s Preferred Chimney Repair Company
We’ve completed more than 38,000 chimney inspections and cleanings since 2009, and a significant share of our repair calls come from Lansdale’s older core. Customers here tend to research before they call, and they stay on the line when we explain what the camera actually showed.
Our reviews from Lansdale homeowners consistently mention the same things: the tech named the problem in plain terms, showed the photo evidence, and delivered a written price before asking for a decision. No verbal estimates that change once the ladder is up. That practice is Clause 1 of the Haven Standard: written scope, written price, written warranty, delivered before work starts.
Response time to Lansdale is typically a few business days for standard repairs, faster for active water intrusion or structural concerns. Dispatch and scheduling are coordinated from our Philadelphia office, but the crew that arrives at your Lansdale door is assigned by name, background-checked, uniformed, and tracked by text when they’re on the way. That’s the “A” and “V” in H.A.V.E.N.: Arrive on schedule, Verified crews.
Local knowledge matters here because Lansdale’s chimney failures follow a specific history. The borough’s compact core grew densely around the North Penn Railroad corridor in the late 1800s and early 1900s, leaving a high concentration of pre-1940 masonry chimneys originally built for coal-burning systems that were later converted to oil or gas. Those conversions frequently left large, unlined flues now badly mismatched to smaller modern appliances, creating chronic draft problems, excessive condensation, and accelerated liner deterioration that is far more common here than in the post-war suburban sprawl of neighboring Hatfield or Montgomeryville. When we inspect a Lansdale chimney, we’re looking for that history before we even raise the ladder.
Our Chimney Repair Services in Lansdale
Chimney Rebuilding
Full rebuilds in Lansdale are most common on the pre-1940 blocks where coal-era stacks have suffered decades of fuel-type changes, freeze-thaw damage, and shared-wall moisture migration. A typical rebuild on a Lansdale row house runs $3,200-$4,200 and includes teardown to sound masonry, reconstruction with matching brick where possible, and a new crown with proper overhang and drip edge. We document the full process with photos at each stage, per Clause 4 of the Haven Standard.
Spalling Brick Repair
Montgomery County’s winters bring repeated freeze-thaw cycling rather than sustained deep freezes, which is particularly destructive to the aging mortar joints and brick spalling found on Lansdale’s oldest chimneys. Moisture infiltrates hairline cracks in October, expands through repeated January thaw-refreeze cycles, and by spring homeowners discover accelerated crown and flaunching failures that need addressing before the next heating season. Spalling repair in Lansdale typically runs $850-$1,800 depending on surface area and whether the damage has reached the wythe (the inner wall separating flues). We replace spalled brick, repoint surrounding mortar, and seal with a vapor-permeable waterproofing agent that lets the masonry breathe.
Flashing Repair
Flashing failures on Lansdale’s older homes often trace to two sources: original step flashing that has corroded through after 80+ years, or more recent counter-flapping jobs that didn’t account for the movement of a heavy masonry stack on a wood-framed roof. Repair runs $650-$1,400. We use copper or lead-coated copper where the chimney meets the roof plane, and we always inspect the adjacent decking for hidden water damage while the flashing is exposed. On shared stacks in Lansdale’s attached housing, we also verify that our repair doesn’t open a path for water into the neighbor’s side.
Mortar Repointing & Tuckpointing
Repointing in Lansdale costs $1,200-$2,800 for a typical two-flue stack. The price varies with scaffold needs on tight row-house lots, where roof access can be constrained by adjacent buildings and overhead lines. We grind out failed mortar to a uniform depth, match the original mortar composition (critical on historic Lansdale masonry where modern Portland cement can trap moisture and accelerate freeze-thaw damage), and tool the joints to shed water.
Chimney Waterproofing
Waterproofing a Lansdale chimney runs $400-$950 and is often the most cost-effective preventive repair we offer. We apply a silane/siloxane-based treatment that penetrates the masonry rather than forming a surface film, which is essential on older brick that needs to exhale moisture from the inside. We recommend it after any repointing or spalling repair, and as a standalone measure for chimneys with sound mortar but porous brick.

Common Chimney Repair Problems We See in Lansdale Homes
- Oversized coal-era flues converted to gas, left unlined. The appliance can’t hold draft in a flue built for a coal furnace. Condensation forms on the oversized terracotta surface, rots mortar from the inside out, and by the time you notice a problem, the liner is cracked and the wythe is compromised. We find this on roughly half the pre-war Lansdale inspections we perform.
- Improperly capped dead flues in multi-flue stacks. Technicians working the older streets near Lansdale Avenue and Broad Street routinely find chimneys with two or three flues where one was capped off when a coal furnace was removed, but improperly capped, allowing animal intrusion and moisture to degrade the shared masonry wall, which then compromises the active flue right next to it.
- Freeze-thaw cycling through hairline cracks. Starting in October, moisture infiltrates. Each January thaw refreezes it. By March, spalled brick and crown failure are visible from the street. The repair is always more extensive than it would have been the previous fall.
- Shared-stack moisture migration in attached housing. On the dense blocks near Main Street, one neighbor’s unsealed dead flue can saturate the masonry wall shared with an active flue, causing liner failure and draft problems in a chimney the other homeowner maintains diligently. We address both sides when both owners agree, or we seal and isolate the shared wall when only one side is accessible.

FAQs - Chimney Repair in Lansdale
Yes, we can repair your flue independently, but we inspect the shared masonry wall and any adjacent dead flues because moisture migration from their side commonly damages yours. On a row house block off Lansdale Avenue, we opened a shared brick stack with two live flues and one coal furnace flue that had been capped years earlier but not sealed against weather, and the capped flue’s damp masonry had migrated into the active flue wall beside it. Our tech relined the active side with a DuraFlex stainless liner sized to the appliance, rebuilt the failed crown and flashing, and repointed the shared stack so the neighbor’s side stopped drawing moisture into ours. We document the shared-wall condition with photos and explain what we can and can’t seal without access to the other unit. Call (484) 806-9176 to schedule an inspection.
Your chimney was built for coal, which required a large flue and often served multiple appliances or even multiple units in a row house. When heating systems converted to oil or gas, the new appliances needed smaller flues, so some were capped off and left dormant. The problem: those dead flues were rarely sealed properly against weather or animals, and their deterioration now threatens the active flue they share a wall with. We see this constantly on the older blocks near Lansdale Avenue and Broad Street. A Level 2 camera inspection shows exactly which flues are active, which are dead, and whether the wythe between them is intact. Call (484) 806-9176 to book.
It needs attention before next heating season, and sooner if you can see gaps or feel drafts from the firebox. Crumbling mortar in Lansdale is typically freeze-thaw damage: moisture entered hairline cracks in fall, expanded through January thaw cycles, and dislodged mortar by spring. Left unaddressed, water reaches the inner wythe, liner damage accelerates, and you risk carbon monoxide leakage or structural failure. Repointing runs $1,200-$2,800 in Lansdale. We grind, match, and seal the joints so the next freeze cycle has no water to work with. Call (484) 806-9176 for a written estimate.
Third-degree (Class III) creosote is less common in Lansdale than in rural areas burning unseasoned wood, but we do find it, especially in older fireplaces where homeowners burn pressed logs or operate dampers incorrectly. More often, we find glazed creosote in the oversized flues left from coal conversions, where reduced draft allows smoke to linger and condense. Class III creosote is a genuine fire hazard and requires mechanical removal, not just brushing. We document the class and extent with camera footage and remove it with rotary chains or chemical treatment depending on thickness. Call (484) 806-9176 if you’ve noticed reduced draft or a tar-like coating in your firebox.
A Level 1 inspection is a visual check of accessible portions, appropriate for annual maintenance on a chimney with no known changes. A Level 2 inspection is what we perform for every repair evaluation in Lansdale: camera scan of the full flue interior, inspection of accessible attics and crawl spaces, and documentation with photos and written findings. Clause 4 of the Haven Standard requires this photo record on every job. Given Lansdale’s prevalence of hidden flue damage from dead-flue moisture and fuel-conversion mismatches, a Level 1 inspection routinely misses the actual problem. We include the Level 2 camera inspection and documented record as standard, not as an upsell. Call (484) 806-9176 to schedule.
