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 Philadelphia
Chimney repair in Philadelphia typically costs $180 for minor mortar repointing up to $8,500 for full rowhouse chimney rebuilds, with most common repairs falling between $1,200 and $3,800. Our crews dispatch from our Philadelphia office and carry DuraFlex liner stock, HeatShield refractory mortar, and crown repair materials on every truck - no waiting on parts to fix what we find.
We’ve worked on Philadelphia chimneys since 2009, and the rowhouse interior chase is a different animal than the exterior chimneys you’ll find in King of Prussia or Chester. In South Philly, Port Richmond, and Kensington, your flue is buried behind plaster and party walls with zero exterior access. That means crown leaks rot your structure from the inside out, and shared flues with neighbors create cross-contamination risks you’d never detect without a camera inspection from the roof. We run NFPA 211 Level 2 camera scans on every call, document what we find with photos, and give you a written price before any work starts. Call (484) 806-9176 for a free estimate.
Why Level Two Chimney Chesterbrook Is Philadelphia’s Preferred Chimney Repair Company
We’ve completed more than 38,000 chimney inspections and cleanings since 2009, and a significant share of those have been in Philadelphia’s rowhouse neighborhoods. Our Chimney Repair team knows the difference between a parlor fireplace flue, a converted furnace flue, and a water heater flue stacked through the same interior chase - because getting it wrong in a rowhouse means venting carbon monoxide into a bedroom.

Our Chimney Repair Services in Philadelphia

Chimney Relining with HeatShield and DuraFlex
This is the repair we find ourselves recommending most often in Philadelphia, and it’s not because we’re pushing liners - it’s because your 1920s rowhouse was built with a coal flue that was never relined when gas came in. The original clay tile is oversized for modern gas exhaust, chemically incompatible, and usually cracked from decades of thermal cycling. In Passyunk and Port Richmond, we regularly pull camera footage showing glazed third-degree creosote on smoke chamber walls where converted oil furnaces ran too cool for too long.
We install DuraFlex stainless steel liners for full relines and apply HeatShield cerfractory sealant for resurfacing damaged clay where the structure is sound. Both come with written warranties, and we show you the before-and-after camera footage so you understand exactly what was failing and why.

Mortar Repointing and Tuckpointing
Philadelphia’s 40-50 annual freeze-thaw cycles grind away at the soft lime mortar in pre-1940 brickwork. In rowhouse blocks where chimneys have no exterior wall exposure, the damage concentrates at the crown and roofline, where water enters and expands behind the brick face. We grind out failed joints to proper depth, match mortar composition to the original, and repoint with color-matched material that doesn’t scream “repair” from the sidewalk. Tuckpointing for decorative mortar lines is available where the original aesthetic matters.

Chimney Waterproofing and Chimney Cap Installation
With roughly 42 inches of annual precipitation hitting Philadelphia, an unprotected crown is a liability. We apply vapor-permeable waterproofing agents that let brick breathe while blocking liquid water, and we install Gelco and Olympia Chimney caps with proper overhang and mesh screening. In tight rowhouse configurations where the chase is interior, the cap is often your only defense - there’s no exterior wall to shed water, so the crown and cap assembly has to perform perfectly.

Flashing Repair and Crown Reconstruction
Rowhouse chimneys terminate at the roof with no side wall to stage from, so flashing inspection requires working at the penetration point on often-steep Philly roofs. We replace deteriorated step flashing, install cricket diverters where roof pitch demands it, and pour new concrete crowns with proper drip edges and slope. Every crown repair includes a photo record of the substrate condition before we cover it - Haven Standard Clause 4 requires documentation, and you get the files.

We source materials through Haven’s buying network specifically to keep customer prices honest: DuraFlex stainless liners for Philadelphia’s relining jobs, HeatShield cerfractory mortar for smoke chamber parging and clay tile resurfacing, and Gelco chimney caps for waterproofing at the termination. Olympia Chimney components round out our cap and flashing inventory. Because we stock these brands on Philadelphia-area trucks, most repairs don’t wait on parts - we quote the job, you approve the written scope, and we execute. No “we’ll order that and come back” delays on standard repairs.
Common Chimney Repair Problems We See in Philadelphia Homes

- Shared flue cross-contamination in attached rowhouses. Your neighbor’s converted furnace or water heater vents into the same interior chimney chase as your gas appliance, and without a top-down camera inspection, the shared stack goes undetected until draft problems or elevated carbon monoxide readings appear. We identify these configurations regularly in North Philly and Kensington rowhouse blocks.
- Crown and flashing failure on interior chases. With no exterior side wall to shed water, deteriorated crowns and flashing gaps let rain migrate silently into plaster and living spaces for years. By the time you see a water stain, the lath behind the plaster is often compromised. We catch this early with roof-level inspection and camera documentation.
- Oversized, cracked clay liners incompatible with modern gas exhaust. The original 1880-1940 coal flues were never relined during mid-century conversions. Their oversized, chemically incompatible clay tiles crack and spall, and the damage is only visible via camera inspection because the chase is buried behind party walls with zero exterior exposure.
- Spalling brick from freeze-thaw cycling. Philadelphia’s winter wet-dry cycles pop the faces off century-old brick, especially at the crown where salt deposition accelerates deterioration. We see this as endemic across South Philly and Port Richmond, not as an isolated defect.

FAQs - Chimney Repair in Philadelphia

The only reliable way to confirm a shared flue is a top-down camera inspection from the roof, because Philadelphia rowhouse interior chases have zero exterior wall access and are buried behind plaster and party walls. We run the camera, trace each flue to its source, and show you the footage. If we find cross-connection, we document it with photos and explain your options for separation or relining. Call (484) 806-9176 to schedule - estimates are free.
Your Philadelphia rowhouse was built with a coal flue sized for a 1880s furnace, then converted to gas or oil in the 1950s-1970s without relining - a shortcut that was common across the city but creates a mismatch between flue diameter and modern appliance exhaust. The oversized clay tile cracks, collects acidic condensation, and can vent carbon monoxide into living spaces. Suburban homes built after 1960 were typically constructed with properly sized flues for the appliances they served. We show you the camera footage of your liner condition and explain whether HeatShield resurfacing or full DuraFlex replacement is appropriate. Call (484) 806-9176 for a free estimate.
We work entirely from the roof and from the appliance connection point, using NFPA 211 Level 2 camera inspection to assess flue condition below the roofline. For repairs, we stage at the roof penetration, remove the cap, and execute crown work, repointing, or relining through the top opening. In tight Port Richmond or Passyunk blocks with minimal roof access, we’ve developed techniques for working in confined staging areas that technicians unfamiliar with Philadelphia rowhouses often refuse. The photo record we deliver shows you everything we found and everything we did. Call (484) 806-9176 to book.
Philadelphia’s 40-50 annual freeze-thaw cycles relentlessly attack soft, aged mortar joints and porous brick faces, especially where water has entered through a failed crown. The damage is concentrated at the roofline because rowhouse interior chases have no exterior wall to shed water. Spalling, open joints, and deteriorated crowns are endemic across South Philly, Port Richmond, and Kensington - not exceptional, but expected maintenance on century-old masonry. We assess the extent with camera and visual inspection, then quote repointing, crown repair, or waterproofing based on what we can document. Call (484) 806-9176 for an exact scope and price.
Stop using your appliance immediately and call us at (484) 806-9176 for emergency camera inspection. Cross-contamination in a shared stack can introduce carbon monoxide from your neighbor’s exhaust into your flue, or create draft interference that pushes your own combustion byproducts into living spaces. We document the shared configuration with camera footage, then recommend separation through individual relining or, in some cases, coordination with your neighbor for simultaneous flue separation. This is not a DIY assessment - the stakes are too high, and the access too restricted, for anything but professional inspection.
