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.

Hellertown sits in the lower Saucon Valley, where the old Bethlehem Steel neighborhoods of twin homes and row houses line streets like Main Street, Water Street, and the slopes below Saucon Park. These homes were built for workers between 1910 and 1950, and their chimneys tell the same story: coal converted to oil, oil converted to gas, the flue never properly resized, and the crown left to crumble through decades of freeze-thaw cycles that run well into March. We’ve been working on chimneys like these for over 42 years. We know what we’ll find before we set the ladder.
Why Hearthstone Chimney Co. Is Hellertown’s Preferred Chimney Cap & Crown Company
Our reputation in Hellertown was built on twin homes and row houses where the chimney stack belongs to two properties, not one. Homeowners here have learned that a cap job done without checking both flues invites callbacks - rain down one flue, neighbor’s furnace exhaust backing into the other, creosote dropping from an uncapped side onto a newly swept liner. We document every stack with our Level-2 camera inspection, show you the photos, and give you a plain-English verdict before we quote.
Response time to Hellertown is same-week for standard bookings, and our technicians arrive background-checked, uniformed, and with the parts to finish in one visit. No-hassle upfront pricing means the number on the estimate is the number on the invoice. Every job carries our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back.
Russell Haines has led Hearthstone Chimney Co. since 1984, and the company plans to be answering calls in this region for decades more. That changes how we work. We don’t chase a quick sale and disappear. We cap your stack knowing we’ll see it again at the next cleaning.
Our Chimney Cap & Crown Services in Hellertown
Cap Installation
New cap installation in Hellertown starts with understanding your flue configuration. On the borough’s dual-flue stacks - common on twins off Walnut Street and the Rentzheimer Hill area - a single-flue cap is worse than no cap at all. It protects one flue while leaving the other open to rain, squirrels, and debris from the neighboring appliance. We measure both flues, check cross-draft patterns, and install either individual caps at proper heights or a single multi-flue cap sized to cover the entire masonry top. Materials are Gelco or Famco galvanized and stainless options, sized for the specific flue diameter and local wind exposure.
Cap Replacement
Cap replacement is our most common call in Hellertown, and the reason is almost always the same: a rusted-through galvanized cap from a big-box store, installed by a previous owner, has finally collapsed into the flue or blown off in a Saucon Valley wind. We remove the old cap, inspect the flue mouth for spalling brick or liner damage that the failed cap allowed to worsen, and install a replacement that fits correctly. On older homes near the Saucon Creek corridor, we often find the original cap was never properly flashed to the crown, so water has been running behind it for years. We fix that too.
Crown Repair
Crown repair is where Hellertown’s climate does its worst damage. The lower Saucon Valley’s cold air drainage intensifies winter temperature swings, and the sharp freeze-thaw cycling into March opens mortar joints and spalls the concrete crown on pre-1960 brick stacks. Water gets in, freezes, expands, and repeats until the crown is cracked through and shedding pieces onto the roof below. We cut out the damaged crown, form and pour a new concrete slope with proper overhang and drip edge, then seal it with a flexible crown coating rated for the thermal movement these stacks see. Most crown repairs run $650-$1,200 depending on stack size and access.
Crown Coating
Crown coating buys time on a crown that’s cracked but not yet structurally failed. In Hellertown, we use this most often on mid-century stacks where the crown is sound enough to save but porous enough to admit water. We clean the crown surface, fill hairline cracks, and apply a flexible, UV-stable coating that bridges future thermal movement. It’s not a substitute for a proper crown pour on a spalled or separated crown, but on the right stack it’s a square deal that extends service life five to ten years. Coating alone runs $280-$450; combined with cap replacement, it’s often the most cost-effective protection we can offer.
Multi-Flue Cap
Multi-flue caps are essential on Hellertown’s dual-flue and shared stacks. These custom-fabricated covers span the entire chimney top, protecting multiple flues with a single structure that sheds water and prevents cross-contamination between flues. We size them to the exact masonry dimensions, with screen height calculated for proper draft on each flue type - gas furnace flues need different clearances than wood-burning fireplace flues. On a recent job off Water Street, a multi-flue cap solved a two-year problem where the neighbor’s high-efficiency furnace exhaust was cooling and dropping into the adjacent fireplace flue, causing persistent moisture damage. Multi-flue caps typically run $480-$890 installed, depending on size and material.
Custom Cap
Custom caps cover everything else: oversized flues, unusual masonry shapes, historic stacks where standard sizes won’t fit, or installations where local ordinance or HOA requirements specify material or style. We fabricate to spec using measurements taken on-site, with turnaround usually under two weeks. In Hellertown’s historic core near the Old Hellertown Cemetery and along Main Street’s older commercial buildings, custom work is sometimes the only option that preserves the building’s character while meeting modern safety requirements.

Trusted Brands We Service in Hellertown
We install and service caps and crowns using professional-grade materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney - brands we’ve specified for decades because they survive the thermal cycling and moisture exposure that destroy builder-grade alternatives. For Hellertown customers, we stock common cap sizes and crown coating materials locally, so most replacements don’t require a second trip. When a custom fabrication is needed, we order direct and track delivery so we’re back on your roof the day the part arrives. No waiting, no excuses, no “we’ll come back when it gets here.”
Common Chimney Cap & Crown Problems We See in Hellertown Homes
- Single-flue caps on dual-flue stacks. A previous installer capped one flue and left the other open, or installed a cap so low that debris from the uncapped flue drops into the capped one. We see this on nearly every block of twins in the borough. The fix is always a multi-flue cap or properly height-separated individual caps.
- Crown water intrusion into cracked clay liners. Hellertown’s 70-100+ year old clay tile liners are already compromised from decades of coal-oil-gas conversion. When a spalled crown admits water, it runs straight into those cracks, accelerating deterioration and creating steam pressure that opens the liner further during heating season.
- Freeze-thaw destruction of pre-1960 mortar and brick. The lower Saucon Valley’s extended freeze-thaw season destroys exposed mortar joints and porous brick crowns. By late March, we’ve already booked a dozen crown repairs on stacks that were intact in October.
- Cross-contamination between adjacent flues. On shared stacks - common in Hellertown’s row and twin housing - a failed or missing cap on one flue allows exhaust, moisture, or creosote to migrate into the neighboring flue. This is a carbon monoxide risk on gas flues and a fire risk on wood-burning flues.

FAQs - Chimney Cap & Crown in Hellertown
A standard single-flue cap replacement in Hellertown runs $180-$340 installed, while a multi-flue cap for the borough’s common dual-flue stacks runs $480-$890. Custom fabrication for unusual sizes or historic requirements starts around $680. Call (610) 632-1394 for an exact quote - estimates are free.
Yes - we work across the borough including the Rentzheimer Hill area, the twin-home blocks off Walnut Street and Main Street, the Saucon Creek corridor, and the older commercial structures near the historic core. We know the access challenges of each: tight alleys between twins, steep pitches on hillside homes, shared driveways where ladder placement requires coordination.
We specify Gelco and Famco for standard and multi-flue caps, Olympia Chimney for specialized flue-top applications, and HeatShield crown coating for preventive sealing and minor crack repair. These are professional-grade materials, not builder-grade substitutes, and we stock common sizes for fast turnaround on Hellertown jobs.
Calls are answered by a live person 24 hours a day, 7 days a week, and we prioritize active water intrusion, animal entry, or storm damage that leaves a flue open. For true emergencies - a cap blown off in high winds, a crown chunk fallen through the roof - we can usually inspect same-day and temp-cap if permanent repair requires custom fabrication. Call (610) 632-1394 any hour.
Every job carries our 90-Day Done Right Promise - in writing, no arguing, no paperwork to file. If it’s not right, we come back. This is company-wide policy, not location-dependent. We’ve honored it on Hellertown jobs twice in the past three seasons: once for a crown coating that didn’t adhere properly due to unexpected moisture in the substrate, once for a multi-flue cap that needed screen height adjustment after the first firing season. Both were fixed within 48 hours of the call.
On a twin off Rentzheimer Hill, our tech pulled a rusted Famco cap off a shared two-flue stack and found the left flue serving the neighbor’s gas furnace, the right flue fully glazed with third-degree creosote from the fireplace below. The crown was spalling badly with open mortar joints on the freeze-thaw face, so we cut and recast the crown, coated it, and set a custom multi-flue cap sized to both flues so debris from one side can no longer drop into the other. The callback risk here isn’t the flue we clean - it’s the one we don’t.
Because so many Hellertown core stacks were built as dual-flue chimneys serving a coal furnace and a fireplace off one masonry structure, a cap or crown job here usually means capping two or more flues at different heights on the same stack - and the neighbor’s appliance can be venting into the flue you haven’t looked at yet. Our Chimney Cap & Crown team checks every flue on the stack, documents what we find with photos you can see, and sizes the solution to protect the whole structure, not just the side that called.
Ready to protect your stack? Call (610) 632-1394 for a free estimate. A live person will answer, we’ll schedule at your convenience, and we’ll give you a plain-English verdict with photos before any work begins. Done right - and we stand behind it.
