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 Cap & Crown Across Fullerton
Chimney cap and crown work in Fullerton, PA typically runs $280-$650 for standard repairs and $340-$890 for full crown rebuilds or custom cap installations, with most jobs completed in a single visit. We’re Hearthstone Chimney Co., and our Chimney Cap & Crown crews have been working the Lehigh Valley for over 42 years. Dispatch runs from our Philadelphia office, and we route trucks to Fullerton daily - usually with next-day or two-day availability, sometimes same-week depending on season. Call (610) 632-1394 and a live person picks up, 24 hours a day.
Fullerton’s not unfamiliar territory for us. The post-WWII ranches along Fifth Street, the cape cods near the Whitehall line, the semi-detached homes off MacArthur Road - we’ve capped and coated crowns on all of them. These chimneys were built for coal and oil, not wood stoves or gas inserts. That matters when you’re choosing a cap. The wrong size, and you’ve got rain in the firebox, creosote in the gap, and a crown that won’t survive another Lehigh Valley winter.
Why Hearthstone Chimney Co. Is Fullerton’s Preferred Chimney Cap & Crown Company
We’ve earned our reputation in Fullerton the slow way: by showing up when we say, documenting what we find with photos the homeowner can see, and standing behind the work with the 90-Day Done Right Promise in writing. No arguing. If it’s not right, we come back.
Our technicians are background-checked and uniformed. They carry professional-grade materials from DuraFlex, HeatShield, and Copperfield on every truck, so most Fullerton jobs finish in one visit. No-hassle upfront pricing means the number on the estimate is the number on the invoice.
Calls get answered by a live person, every hour of every day. Not a voicemail tree. Not a callback queue. A real person who can book your appointment or answer a question about your chimney crown while you’re looking at the crack.
We know the local conditions: the hard freeze-thaw cycles that spall mortar on Fullerton’s older brick crowns, the shallow-pitched ranch roofs that trap ice against chimney flashing, the coal-era flues that need caps sized to the opening, not the appliance. That local knowledge changes what we recommend and how we build it.
Our Chimney Cap & Crown Services in Fullerton
Crown Repair
Crowns on Fullerton’s 1940s-70s brick chimneys take a beating. The Lehigh Valley sits in a bowl between South Mountain and Blue Mountain, which channels cold air and drives aggressive freeze-thaw cycles through winter. Water seeps into hairline cracks, freezes, expands, and spalls the concrete. We’ve rebuilt crowns on ranches off Fifth Street where the crown had deteriorated to exposed aggregate, letting water run straight down into the smoke chamber.
Our crown repair process starts with a camera inspection so you see the damage yourself. We remove loose material, apply a bonding agent, and pour a new cementitious crown with proper slope and drip edge - built to shed water, not collect it. Most crown repairs in Fullerton run $340-$520 and finish in one day.

Crown Coating
Not every cracked crown needs rebuilding. If the structural concrete is sound but the surface is weathered, Crown Coating extends the life five to ten years at roughly half the cost of a rebuild. We use professional-grade flexible coatings formulated for the thermal cycling these crowns see.
In Fullerton, Crown Coating is often the right call for homeowners who caught the damage early - before freeze-thaw opened gaps wide enough to let water reach the flue. Typical range: $280-$420. We won’t sell a coating if the crown is too far gone. Photos first, verdict second, work third.

Custom Cap & Multi-Flue Cap
Here’s where Fullerton’s housing stock changes the math. Your post-WWII ranch or cape was built with a wide, rectangular flue sized for a coal stoker or fuel-oil furnace. Maybe a previous owner stuffed a gas insert down it with a flexible liner, or maybe you’re burning a wood stove connected to that original flue. Either way, a stock cap from a hardware store won’t fit properly. It’ll cover the liner and leave the old flue opening exposed, or it’ll sit crooked on a crown that’s the wrong shape.
We fabricate and install custom caps and multi-flue caps sized to your actual flue opening - not the firebox, not the insert, the opening. A properly sized multi-flue cap on a coal-era chimney seals the entire top, stops downdrafts, keeps animals out, and prevents the moisture wicking that turns second-degree creosote into a chimney fire hazard. Custom caps in Fullerton typically run $420-$890 depending on metal choice and complexity.

Cap Installation & Replacement
Standard cap installation on a properly lined, correctly sized flue is straightforward. We stock Gelco and Olympia Chimney caps in common sizes for fast turnaround. If your existing cap is rusted through, wind-damaged, or was never the right size to begin with, we remove it, assess the crown beneath, and install a cap that actually fits. Most cap-only replacements in Fullerton run $180-$340.
But we always check what’s underneath. A cap is only as good as the crown it sits on. We won’t bolt a new cap onto a crumbling base.

Common Chimney Cap & Crown Problems We See in Fullerton Homes
- Freeze-thaw spalling on 1950s-70s crowns. The Lehigh Valley’s hard winters open cracks in concrete crowns that were never built with air-entrainment or proper reinforcement. By March, we’ve seen crowns on Fullerton ranches reduced to gravel. Water follows the cracks straight to the flue liner, or to the unlined brick if there is no liner.
- Stock caps on oversized coal flues. A cap sized for a 6-inch round liner leaves half a 12-by-16-inch rectangular flue opening exposed. Squirrels get in. Rain gets in. Downdrafts blow smoke into the living room. We see this constantly on Fullerton homes where a previous owner or a handyman grabbed whatever was on the shelf.
- Wood stoves connected to unlined coal flues. The wide flue stays cold, creosote condenses on the brick, and because the homeowner never got a Level 2 inspection after the stove went in, third-degree glaze builds for years. The cap, if there even is one, was never sized for this setup and doesn’t vent properly.
- Ice damming and flashing failure on shallow ranch roofs. Fullerton’s ranches with their low pitches collect ice at the chimney base. Water backs up under flashing, rots the roof deck, and enters through the chimney structure. A sound crown and properly flashed cap assembly are the first defense.
Pricing for Chimney Cap & Crown in Fullerton, PA
| Service | Typical Range in Fullerton |

What moves the number? Crown size and accessibility. A ranch with a straight shot at the roof is simpler than a cape with a steep second-story pitch. The extent of spalling - surface cracks versus exposed rebar - determines whether we coat, patch, or pour new. Custom cap fabrication in stainless or copper costs more than galvanized steel, and lasts longer.
Every estimate starts with a Level 2 camera inspection: $89 during our seasonal tune-up, credited toward the work if you proceed. No surprises on the bill. Call (610) 632-1394 for an exact quote - estimates are free.

FAQs - Chimney Cap & Crown in Fullerton
We can cap it, but the cap must be sized to the flue opening, not the firebox or any insert inside it. A stock cap sized for a 6-inch liner on a 12-by-16-inch coal flue leaves the opening partly exposed. We fabricate multi-flue caps or custom caps that seal the entire top. Call (610) 632-1394 and we’ll measure it properly.
A wood stove connected to an unlined or improperly lined coal-era flue should be inspected annually and swept when creosote reaches 1/8 inch. In practice, with Fullerton’s cold winters and the thermal inefficiency of wide, unlined flues, that’s often every season for primary-heat stoves. The camera inspection tells you exactly where you stand.
The Lehigh Valley’s freeze-thaw cycles attack concrete crowns that were poured without modern air-entrainment or proper slope. Water enters micro-cracks, freezes, and pops off surface layers. By the time you see gravel on the roof, the crown is compromised. Crown coating catches it early; rebuild fixes it late. We’ll show you which with photos.
Probably not. Most gas inserts use a flexible liner smaller than the original flue. If the cap was never changed, it may be sized for the old flue and leak around the new liner, or it may be sized for the liner and leave the old flue open. Either way, it’s wrong. Our camera inspection shows exactly what’s up there and what cap fits.
No. Our standard rates apply across the Lehigh Valley service area, including Fullerton. The estimate is free, and the price we quote is the price on the invoice. Call (610) 632-1394 to book - a live person answers, any time.
On a ranch off Fifth Street in Fullerton, a homeowner burning a wood stove as primary heat called us after a rain-soaked firebox; our tech’s camera scan found a stove connector dumping into the original wide coal flue with no flue liner, so the gap between the flue wall and the pipe was packed with second-degree creosote that had been wicking moisture down for years. We set a properly sized Copperfield multi-flue cap, coated a spalled chimney crown that the freeze-thaw had opened, and wrote the homeowner a burn-practice card for the stove; the next March visit showed a crown still intact and creosote back at first-degree only.
Fullerton’s post-WWII ranches and capes were built with wide, unlined coal- and oil-era flues, so a chimney cap and crown has to be sized to a flue opening far larger than any modern wood stove or gas insert actually needs - a cap sized for the firebox, not the liner, is the wrong cap here. That distinction changes the creosote and moisture math on every wood-stove chimney in this neighborhood. We’ve seen it. We measure it. We build it right.
