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 Cap & Crown Across Allentown
Chimney cap and crown work in Allentown usually runs $425-$2,300 depending on whether you need a simple cap replacement or a full crown rebuild with a custom multi-flue cap. Most jobs are completed in a single visit because our crews carry the common cap sizes and crown materials with them into Allentown’s row-home neighborhoods. We work across the city, from the South Side to the West End, and our team knows the older brick stacks along 7th Street and the surrounding blocks better than most. Call (980) 580-8641 for a written quote before anyone steps on a ladder.
Why Emberly Chimney Cleaners Is Allentown’s Preferred Chimney Cap & Crown Company
Allentown’s housing stock predates modern chimney standards. Most of the row homes and twins in Center City and the South Side were built before 1940, and their chimneys were sized for coal furnaces, not the gas appliances they vent today. That means the cap and crown work here isn’t a simple parts swap. It’s an audit of what’s actually happening at the top of the stack, and we’ve been doing that audit with a camera since 2009.
We’re the company that made camera-scan documentation the default. Clause 4 of the Haven Standard requires a photo record on every job. When we tell you your crown is spalling or your flue is oversized for your furnace, we show you the footage. You see the cracked mortar. You see the uncapped abandoned flue next to the active one. Nothing gets recommended without evidence you can look at yourself, and nothing gets a price until the scope is in writing.
Corrine Halstead leads our team, and every technician who shows up in Allentown is background-checked and uniformed, with a license number on the page and a text sent when they’re on the way. Our crews coordinate from the Philadelphia office and dispatch locally. The person who answers your call at (980) 580-8641 is a trained scheduler, not a voicemail tree, and they can tell you what a crown repair typically costs in Allentown before you ever book.
Our Chimney Cap & Crown Services in Allentown
Cap Installation
A properly fitted cap keeps rain, birds, and debris out of the flue. In Allentown’s attached row-home blocks, that’s not just a comfort issue. An uncapped abandoned flue sharing the same masonry stack as your active gas flue channels cold outside air and moisture directly into it. We install stainless caps sized to the actual flue opening, not a one-size-fits-all piece from a hardware store. For Allentown row homes, that often means a custom cap matched to the coal-era opening that was never resized when the conversion to gas happened.
Cap Replacement
Rusted or blown-off caps are common after Lehigh Valley windstorms. When we replace a cap in Allentown, we check the flue opening beneath it. If the clay liner is cracked or the opening is oversized for the appliance it serves, a new cap alone won’t fix the draft problem. The replacement gets sized in writing, with the measurements in the quote. You see exactly what you’re paying for before we touch the chimney.
Crown Repair
The crown is the concrete or mortar slab that seals the top of the chimney. Allentown’s freeze-thaw cycling crosses the 32°F threshold dozens of times each heating season. Water seeps into hairline cracks, freezes, expands, and splits chunks off the crown over a few winters. By the time we see many Allentown crowns, the spalling has exposed the flue tiles and let water run behind the flashing. We grind down the loose material and rebuild the crown with a proper overhang and drip edge so water sheds away from the masonry. This is the single most common repair we do on pre-WWII Allentown row homes.
Crown Coating
For crowns that haven’t yet spalled but are showing surface cracking, we apply a flexible crown coat that seals micro-cracks and moves with the freeze-thaw cycle. It’s not a substitute for a rebuild when the concrete is failing structurally, and we’ll tell you plainly when a coating is enough and when it isn’t. In Allentown’s older stacks, we often recommend a crown inspection with a camera scan at the same time so you’re not just sealing over a liner problem you can’t see.
Multi-Flue Cap and Custom Cap
Allentown’s row blocks frequently have a single chimney stack containing two or three separate flues serving different units or appliances. A multi-flue cap covers all the openings under one hood, and for attached homes where a neighboring unit’s flue has been abandoned for decades, that shared coverage matters. We fabricate custom caps in stainless steel for non-standard Allentown stacks, including the oversized coal-era openings that no stock cap fits. Our Chimney Cap & Crown team documents the measurements, the fabrication spec, and the finished installation in your photo record.

Common Chimney Cap & Crown Problems We See in Allentown Homes
- Oversized coal-era flues condensing flue gases. Allentown’s pre-WWII row homes were built with large-bore clay-tile flues sized for coal. Converted to gas without relining, those flues never get hot enough to push combustion gases out efficiently. The gases condense inside, producing first- and second-degree creosote that fast-tracks into third-degree tar glaze. A new cap alone won’t solve this. The flue needs to be right-sized, and we show you the camera footage before recommending anything.
- Uncapped abandoned flues in shared row-home stacks. This failure mode barely exists in Whitehall or Lower Macungie because those homes are single-family and were built later. In Allentown’s attached blocks, a neighboring unit’s long-abandoned oil-burner flue often sits uncapped in the same exterior stack as your active gas flue. That opening funnels cold air and moisture straight into your chimney, and the fix is a custom cap or a properly sealed abandonment, documented with photos.
- Freeze-thaw spalling on exposed crowns. Allentown regularly crosses the 32°F threshold dozens of times per heating season. Water enters micro-cracks in the crown, freezes, expands, and widens the gaps over several winters. What starts as a hairline crack turns into a spalled crown with exposed flue tiles and water running behind the flashing. Crown coating seals the early damage; crown repair rebuilds it when the concrete is failing.
- Tall, narrow stacks worsened by Lehigh Valley wind. The valley’s topography channels cold northwest winds off South Mountain in winter. Allentown’s 19th- and early-20th-century row-home chimneys are tall and narrow, and that combination makes downdraft problems worse than in the surrounding suburban townships. A properly sized cap with the right mesh and a crown that sheds water correctly both matter more here than on a newer suburban chimney.
Pricing for Chimney Cap & Crown in Allentown, PA
Here’s what Allentown homeowners can expect to pay. A standard stainless cap installation runs $425-$800 on a single flue. Cap replacement on an oversized coal-era opening with a custom-fabricated cap runs $650-$1,100. Crown coating for surface cracking runs $600-$950. A full crown repair with grinding, rebuilding, and a proper overhang runs $1,100-$2,300 depending on access and the size of the stack. A custom multi-flue cap for a shared row-home stack generally falls between $900 and $2,300.
What changes the price in Allentown? Roof access matters. Row homes with flat roofs and shared parapets are often easier to reach than a steep twin with a pitched roof. The condition of the existing crown matters more. If the concrete is spalled to the point of structural failure, coating won’t fix it and a rebuild is the honest quote. We put the price in writing before work starts, with the scope and the warranty documented. Call (980) 580-8641 for a written quote.

FAQs - Chimney Cap & Crown in Allentown
In most Allentown row homes, a cold draft on a mild day points to an uncapped or abandoned flue in the same shared masonry stack as your active flue. Cold outside air flows down the open flue, chills the shared chimney mass, and gets pulled into your home through the active flue. It’s a structural issue specific to attached housing, not an appliance problem. The fix is verifying the opening with a camera and capping or sealing it properly. Call (980) 580-8641 and we’ll show you exactly what’s open.
Allentown sits in a valley that crosses the freezing threshold dozens of times each winter. Water enters micro-cracks in the crown during the day, freezes and expands at night, and widens the crack over repeated cycles. The city’s pre-WWII brick chimneys have crowns that were built with older, more porous mortar than newer suburban construction, so they absorb more water per cycle. The damage compounds faster. Sealing early cracks with a flexible crown coat costs a fraction of a full rebuild, and we’ll tell you if that’s the right step based on camera footage.
Clay flue liners in coal-era Allentown chimneys were sized for high-volume coal combustion. When the home converted to gas, the flue became dramatically oversized. Gas appliances don’t produce enough heat to keep the large flue warm, so combustion gases condense inside the clay tiles instead of exiting. That condensate is acidic and eats at the mortar joints between tiles, plus the moisture accelerates spalling in the crown above. The liner fails from the inside out, and the crown cracks from the top down. Both show up clearly on a camera scan, and we don’t recommend any repair without showing you that footage first.
If your chimney stack contains two or more flue openings, whether they’re both active or one is abandoned, a multi-flue cap is the correct solution in Allentown’s attached housing. Row-home stacks on blocks along 7th Street and across the South Side typically have multiple flues sharing one masonry structure. A single-flue cap on each opening often doesn’t shed water or block cross-drafts as well as one properly fabricated multi-flue cap. We measure, quote in writing, and show you the fabrication spec before ordering.
Creosote is measured in three degrees. First-degree is fine, dusty soot. Second-degree is flaky and granular. Third-degree is a hardened tar glaze that refuses to be removed by brushing. Allentown row homes are more prone to third-degree because their oversized coal-era flues condense flue gases aggressively. The gases cool too quickly in the oversized flue, depositing creosote faster, and the repeated condensation bakes it into glaze. Third-degree creosote is a fuel source for chimney fires, and it usually means the flue needs to be right-sized, not just swept. We’ll show you the grade on camera and quote the correct fix in writing. Call (980) 580-8641.
