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 Fullerton
Chimney cap and crown work in Fullerton, PA typically runs $340-$890 depending on whether we’re sealing a cracked crown or installing a custom multi-flue cap, and most jobs are completed in a single visit with upfront pricing agreed before we start. We’re Hearthstone Chimney Co., and our crews have been working the Lehigh Valley’s older housing stock for over 42 years. If you live in Fullerton, your chimney was likely built for coal and converted to gas - that matters for how the crown fails and why the cap fits wrong. Call (610) 595-5754. A live person answers, 24 hours a day.
Dispatch and scheduling for Fullerton runs through our Philadelphia office, but our technicians live in the Valley and know the difference between a 1950s Fullerton cape cod off W. Turner Street and a 1970s ranch near Mauch Chunk Road. We’ve replaced crowns on brick rowhomes along the Hamilton Street corridor and fitted multi-flue caps on converted doubles near the Fullerton Dam. That local knowledge means we spot the coal-era problems other sweeps miss.

Our Chimney Cap & Crown Services in Fullerton
Cap Installation
New cap installation on a Fullerton chimney starts around $340-$520 for a standard single-flue galvanized or stainless unit, and $580-$890 for a custom multi-flue cap on a coal-era stack with multiple appliances. Most Fullerton homes we see need the latter. That original coal-fired flue was oversized, and when the furnace converted to gas, the new liner or reduced flue opening often leaves gaps a standard cap won’t seal. We measure with a camera first, then source from Copperfield or Famco to fit the actual geometry - not the theoretical one.
Cap Replacement
Cap replacement in Fullerton runs $290-$640 depending on whether we’re swapping like-for-like or adapting to a modified flue. The post-war caps on Fullerton’s cape cods and ranches were sized for 8×12 or 12×12 terra-cotta flues meant to handle coal exhaust. Slap a 5-inch gas liner inside that flue and the old cap sits loose, rattles in wind, and lets rain pool on the crown below. We see this constantly on homes near the Fullerton Fire Company station and along the older streets toward the Lehigh River. Our replacement caps are measured to the current flue, not the original one.
Crown Repair
Crown repair in Fullerton typically costs $420-$680 for partial rebuilding and resurfacing, or $740-$1,150 for full tear-off and pour on a larger coal-era stack. Here’s the local problem: Fullerton’s original single-wythe brick crowns were poured flat or with minimal slope because coal exhaust was hot enough to evaporate any water that landed. Modern gas furnaces run cooler. Water sits. Then Lehigh Valley freeze-thaw cycling - those weeks in January and February when temperatures oscillate around 32°F day and night - expands that moisture and cracks the crown within a few seasons. We slope and seal every crown repair to shed water, and we document the before-and-after with photos you can see.
Crown Coating
Crown coating, when the concrete is sound but weathered, runs $340-$520 in Fullerton. We use professional-grade flexible sealers, not hardware-store brush-on products that crack by spring. This is often the right call for a Fullerton homeowner whose crown has minor alligatoring but no structural separation from the brick below. Our tech checks with a camera and hammer test first. If the crown is too far gone, we’ll say so plainly. No coating over a failed base - that’s not a repair, it’s a delay.
Multi-Flue Cap
Multi-flue cap installation in Fullerton ranges $640-$980, and it’s the right solution for many of the converted doubles and rowhomes near Hamilton Street where two or three appliances - furnace, water heater, maybe a fireplace insert - vent into one oversized coal-era stack. A multi-flue cap covers the entire crown, protects the masonry from direct rain, and gives each flue its own screened opening. We size these from Famco and Copperfield to overhang the crown by at least 2 inches on all sides, which is critical on Fullerton’s older chimneys where the crown itself may already be compromised.
Custom Cap
Custom caps for unusual flue configurations or heritage masonry run $780-$1,340 in Fullerton. We’ve fabricated custom solutions for Fullerton homeowners with decorative corbelled brick tops, offset flues from multiple heating conversions, and other quirks of 1940s-1960s construction that no catalog cap fits.

Common Chimney Cap & Crown Problems We See in Fullerton Homes
- Flat or reverse-sloped crowns cracking from freeze-thaw. Fullerton’s original coal-era crowns were poured with little or no slope because coal exhaust ran hot enough to flash off moisture. Modern gas appliances don’t. When Lehigh Valley temperatures hover around freezing for weeks, water trapped in porous concrete expands and contracts until the crown spalls and separates from the brick. We see this on nearly every 1950s cape cod in Fullerton.
- Oversized flues creating condensate that destroys from the inside. Fullerton’s coal-era chimneys were built with terra-cotta flues sized for anthracite furnaces. Convert to an 80% gas furnace and the flue never warms enough to establish draft. Acidic condensate pools at the bottom and dissolves mortar joints and clay tile. The cap and crown look fine from the ground while the liner fails. Camera inspection catches what eyes cannot.
- Post-war caps that don’t seal on converted gas flues. That original cap was built for a 12-inch flue. Now there’s a 5-inch liner inside it, or a reduced opening, and the cap sits loose or is adapted with cobbled sheet metal. Rain gets in. Animals get in. And the homeowner doesn’t realize the crown beneath is rotting because the cap “looks okay.”
- Efflorescence and white staining mistaken for cosmetic aging. That white powder on Fullerton brick is minerals left behind when water migrates through the masonry. It means water is getting in, usually through a cracked crown or failed cap seal, and carrying salts from the mortar. It’s not cosmetic. It’s a symptom of ongoing moisture damage that accelerates every freeze-thaw cycle.

We inspect with a camera before quoting, show you the photos, and agree on a fixed price before any work begins. Estimates are free. Call (610) 595-5754 for yours.
We were called out to a 1950s brick cape on W. Turner Street where the homeowner kept finding white powder staining the chimney’s exterior brick; our tech ran a camera and found badly pitted clay tiles with efflorescence-crusted mortar joints - the signature of an oversized coal-era flue venting a modern 80% gas furnace. We installed a correctly sized HeatShield liner, then topped the stack with a custom Copperfield multi-flue cap and rebuilt the cracked crown to shed water away from the spalling brick. Annual camera-verified cleanings have kept the replacement liner clear since.

FAQs - Chimney Cap & Crown in Fullerton
Your crown keeps cracking because gas exhaust is cooler and wetter than coal exhaust, so water now sits in the concrete instead of evaporating, and Fullerton’s freeze-thaw cycles expand that water until the crown fails. The original flat or nearly flat pour made sense for coal. It doesn’t for gas. We rebuild with proper slope and professional-grade sealers designed for the Lehigh Valley climate. Call (610) 595-5754 for a free inspection and exact quote.
Yes - we use Level-2 camera inspection to show you exactly what is happening inside your flue, and we recommend nothing without photo evidence you can see for yourself. If the liner is sound and the crown is the problem, we say so plainly and quote crown repair only. If the liner is failing, we show you the pitting, the gaps, the efflorescence, and explain why addressing the cap or crown alone would be a temporary fix on a deeper problem. The decision is yours. We document, explain, and stand behind whatever you choose.
A multi-flue cap covers the entire chimney top with a single hood that protects the crown from rain while giving each appliance its own screened vent opening, preventing cross-drafting and backdrafting in an oversized flue that was never designed for multiple modern appliances. On Fullerton’s converted rowhomes and doubles, this is often the only way to properly cap a stack that now serves a furnace, water heater, and perhaps a fireplace insert. We size the overhang to shed water beyond the spalling brick, which buys time on aging masonry.
White staining - efflorescence - means water is migrating through your masonry and carrying dissolved salts to the surface, which indicates a failed crown, loose cap, or compromised mortar joints that are letting moisture in. On Fullerton’s coal-era chimneys, this almost always pairs with hidden liner damage from condensate pooling inside an oversized flue. It’s not cosmetic. It’s a warning that the chimney is taking on water and the freeze-thaw damage is accelerating. Camera inspection reveals the full picture.
Every year, without exception - because in Fullerton, the real damage comes from your furnace, not your fireplace. That 80% gas furnace runs all winter, producing acidic condensate in an oversized coal-era flue that never warms enough to draft it out. The liner deteriorates whether you light fires or not. Annual Level-2 inspection with camera documentation catches pitting, joint failure, and crown damage before they become expensive rebuilds.
