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 Allison Park
Chimney cap and crown work in Allison Park typically runs $340 to $1,150 depending on whether we’re repairing a crown, coating one, or fabricating a custom multi-flue cap. Most jobs are completed in one visit. A cracked crown or missing cap isn’t cosmetic, it’s how water gets into your flue and starts tearing apart mortar from the inside. We’ve worked on hundreds of Allison Park chimneys, and the ones giving homeowners the most trouble are usually the ones that look fine from the driveway. Call (980) 580-8641 and we’ll put a camera up the flue before anyone quotes you a dollar.
Allison Park’s housing stock is specific, and it rewards a crew that knows what they’re looking at. The split-levels and colonials spread through Hampton Township between the mid-1950s and mid-1980s were built with masonry chimneys engineered for a different era, oil furnaces, coal heat, wood fires. Most have since been converted to natural gas, and that conversion quietly changed what the chimney has to handle. We see it in the caps and crowns first.
Why Emberly Chimney Cleaners Is Allison Park’s Preferred Chimney Cap & Crown Company
Three things set us apart in Allison Park. First, we don’t quote without camera evidence. Every visit includes a Level 2 camera scan down the flue, and you see the photos before anyone discusses a repair. Clause 4 of the Haven Standard requires a documented photo record on every job, and we’ve run that way since 2009. Second, our pricing is written down before work begins. A written scope, a written price, and a written warranty, delivered up front. Not a ballpark after the tech is already on your roof. Third, our crews know Allison Park’s peculiar failure modes. When a split-level off Mt. Royal Boulevard has a chimney buried against a rising slope, we know to check the lower courses for freeze-thaw damage that a ground-level inspection would miss. That’s not generic chimney knowledge. That’s specific to this terrain.
Corrine Halstead runs our cap and crown division, and she’s the one who signs off on every Allison Park job. If a report says a crown is spalling, Corrine has seen the camera footage herself. Background-checked, uniformed technicians arrive on schedule with a text when they’re en route. Call (980) 580-8641 and a live person answers, 24/7.
Our Chimney Cap & Crown Services in Allison Park
We handle the full Chimney Cap & Crown spectrum in Allison Park, but most of our work here falls into four categories. Here’s what each actually involves.
Crown Repair
The crown is the concrete or mortar slab that caps the top of the chimney and sheds water away from the flue. In Allison Park, crowns take a beating. Freeze-thaw cycles, for one, Pittsburgh gets roughly 40 inches of snow a year and the temperature swings around freezing dozens of times each winter. Water seeps into micro-cracks, freezes, expands, and pries the crack wider. Spalling, the flaking and crumbling you see on old crowns, is the result. We repair crowns by rebuilding the damaged section, typically with a proper overhang and a drip edge so water stops running down the brick face. A crown repair in Allison Park generally runs $425 to $700 depending on the size of the damaged area.
Crown Coating
A crown that’s structurally intact but porous can be sealed with a flexible coating like Gelco. This is common on Allison Park homes where the crown hasn’t cracked yet but has lost its skim coat and is absorbing water. Coating buys years before a full rebuild is needed. We apply it after cleaning and prepping the surface, and we photograph the result. Crown coating in Allison Park runs $340 to $520 for a standard single-flue chimney. On split-levels where the crown is hard to access from below, we set up staging to reach it safely rather than leaning a ladder against a damaged chase.
Cap Installation
A cap does two jobs: it keeps rain, snow, and leaves out of the flue, and it keeps animals, squirrels and raccoons are regulars in Allison Park, out of your chimney. It also has a third, less obvious job on converted homes. If your chimney vents a gas furnace through an old clay tile liner, the cap has to be sized correctly to prevent backdrafting while still keeping water out. We install caps sized to the actual flue dimensions, not a generic one-size-fits-all unit. Cap installation in Allison Park typically runs $220 to $410 for a standard stainless cap.
Cap Replacement
If your existing cap is rusted through, blown off, or the wrong size for the flue, replacement is straightforward but worth doing right. We measure the flue, check the crown condition underneath, and install a replacement that actually fits. In Allison Park, where many chimneys still have the original clay tile from the 1960s and 70s, we often find caps that were never properly sized in the first place. A replacement cap runs $180 to $380 installed.

Common Chimney Cap & Crown Problems We See in Allison Park Homes
- Spalled crowns from freeze-thaw cycling. Allison Park sits in the North Hills, and winter temperatures swing around freezing all season. Water works into hairline cracks, freezes, and flakes away the crown surface. Early spalling is fixable with a rebuild; ignored spalling means water reaches the flue liner and the chase.
- Acidic condensate eating crowns from below. Homes converted from oil to natural gas vent lower-temperature, higher-moisture exhaust through clay tile liners that were oversized for oil. The condensate is mildly acidic. It rises, condenses at the crown, and etches the mortar and cap flanges over time.
- Buried chimney bases on uphill lots. In Hampton Township subdivisions, many split-levels sit on sloping lots where the grade rises nearly to the chimney base. The lower courses stay damp, freeze and thaw, and erode invisibly. A cap or crown that looks bad from the driveway may be hiding damage at the base that’s been progressing for years.
- Debris-clogged caps under tree canopy. Allison Park lots back up to wooded corridors and hardwood branches hang over rooftops. Leaves and twigs land on caps, trap moisture against the crown, and speed up spalling. We recommend an inspection every two years if your chimney sits under a canopy.
Pricing for Chimney Cap & Crown in Allison Park, PA
Here’s where Allison Park pricing actually lands, based on the work we’ve done in Hampton Township. Crown coating runs $340 to $520. Crown repair runs $425 to $700. Standard cap installation runs $220 to $410. A custom multi-flue cap, which many Allison Park split-levels need because they have two flues sharing one stack, runs $580 to $1,150. A full custom cap fabricated for an unusual flue configuration can push toward $1,400. What moves the number: access difficulty, flue count, crown condition underneath, and whether we’re matching an existing cap or designing from scratch.

FAQs - Chimney Cap & Crown in Allison Park
The tell is a flaking, sandy surface with small crescent-shaped chips missing, often concentrated on the corners and edges where water sits. Freeze-thaw spalling looks like erosion; old age looks more like uniform wearing. You’ll also usually see efflorescence, white mineral staining, on the brick below the crown. In Allison Park’s wet, cold winters, spalling advances in a season or two. The fix is a crown rebuild before the damage reaches the liner. Call (980) 580-8641 and we’ll put a camera on it and show you exactly what’s happening.
Split-levels in Allison Park were typically built with two flues in a single stack: one for the furnace or boiler, one for a fireplace. The flue openings are often different sizes, and the spacing between them doesn’t match stock caps. A custom multi-flue cap fabricated to the actual dimensions is the correct fix, and it’s what we recommend rather than jerry-rigging two single caps onto one crown. We measure on site and order the cap from Copperfield cut to size.
Yes, and this is a real issue on Hampton Township lots where grade rises to meet the chimney. The cap can look straight and dry while the lower courses, buried or partially buried, are eroding out of sight. We check what’s below grade when the terrain allows, and we always run the camera down to the base of the flue. If water is getting in at the bottom, a new cap up top won’t stop it. The camera report shows what the driveway view doesn’t.
Gas exhaust is cooler and wetter than oil exhaust. In a clay tile liner sized for oil, that moisture condenses before it exits, and the condensate is slightly acidic. Over years, it etches mortar and corrodes cap flanges and the underside of the crown. The crown doesn’t just crack from freeze-thaw; it actually loses material from the chemical attack. A Gelco crown coating applied after cleaning can arrest the surface damage, but if the liner is badly deteriorated, a DuraFlex liner may be needed to properly vent the gas appliance. We’ll show you the camera footage before recommending anything.
Every two years. Allison Park’s tree canopy means caps fill with leaves and twigs, and the debris holds moisture against the crown and mortar. Homes backing up to wooded corridors, off Mt. Royal Boulevard or along the green space near Hampton Community Park, are the ones we see with clogged caps and accelerated spalling. An inspection with a camera scan takes under an hour and gives you a photo record you can compare year over year.
