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.

We’ve been dispatching crews to Bangor from our Philadelphia office for decades. We know the borough’s slate-roof worker cottages along Broadway and the brick rowhouses clustered near the old quarry yards. We know that a “simple cap replacement” call here often turns into something more interesting once we get up on the roof. Bangor chimneys are old, most built for coal, many unlined, and the freeze-thaw cycling coming off Blue Mountain is harder on mortar than what you’ll find down in the Lehigh Valley. That’s why our Chimney Cap & Crown team brings a Level-2 camera to every job, and why we don’t recommend anything you can’t see for yourself.
Why Hearthstone Chimney Co. Is Bangor’s Preferred Chimney Cap & Crown Company
Bangor homeowners tend to stay put. They’ve owned their houses for twenty, thirty, forty years. They’ve also been burned by contractors who showed up, guessed at the problem, and sold them work they didn’t need. We don’t work that way. Every inspection ends with photos and a plain-English verdict. The 90-Day Done Right Promise covers every cap and crown job in writing. If it’s not right, we come back. No paperwork to dig up, no argument.
Our technicians are background-checked, uniformed, and trained to work on century-old masonry. Most jobs finish in one visit. The price we quote is the price on the invoice. We’ve answered the phone with a live person for over 42 years, and that includes 2 AM on a January night when a Bangor homeowner smells something wrong from their fireplace.
We understand the local housing stock. The late Victorian rowhouses on South Main Street, the quarry cottages off Market, the converted duplexes near the old slate yards. These chimneys weren’t built for modern inserts and stainless steel liners. They were built for coal stoves, vented into unlined brick flues or clay tile that has been slowly deteriorating since the Harding administration. A technician who doesn’t know that history will sell you a cap when your real problem is a crown that’s been funneling water into spalled brick for a decade.
Our Chimney Cap & Crown Services in Bangor
Cap Installation
New cap installation in Bangor runs $220-$480 for standard single-flue models, with multi-flue caps for the borough’s larger homes or converted duplexes starting at $550. We size caps to fit the actual flue opening, not the closest stock size from the truck. On Bangor’s older chimneys, that matters. Many original flues are oversized for modern appliances, or have been partially lined with clay tile that reduces the effective opening. A cap that’s too small traps moisture. A cap that’s too large lets in wind-driven rain from Blue Mountain downdrafts. We measure, we photograph, we fit.
We install Gelco and Famco caps with stainless steel mesh that won’t rust out in three winters. The hardware is galvanized or stainless, never aluminum that fatigues in the freeze-thaw cycle. Every installation includes a camera look down the flue to confirm the crown beneath is sound. We’re not putting a new cap on a crown that’s already crumbling.

Cap Replacement
Cap replacement in Bangor costs $180-$420 depending on accessibility and whether the existing mounting hardware has corroded into the flue tile. We see this often on homes near the ridge line where wind exposure is worst. The old cap blows off or rusts through, and the homeowner assumes that’s the end of it. But we always check why the cap failed. Was it poor fit? Crown deterioration underneath? Or water coming in from failed step-flashing at the slate roof junction, which accelerates corrosion of everything metal on the chimney?
On a slate-roof worker cottage near the Bangor borough core, our crew pulled a crumbling mortar crown that had been shedding into an unlined flue for years. Every rainstorm was washing crown grit straight down onto the smoke chamber shelf. We reset the crown, coated it, and installed a custom multi-flue cap sized for the two original flues plus the clay tile liner the homeowner had added decades ago, then ran a Level 2 inspection camera to prove the terra cotta below was still sound before we’d sell anything else. The water intrusion they’d blamed on the cap was actually failed step-flashing where slate met brick, which we flagged with photos the homeowner could see.

Crown Repair
Crown repair in Bangor typically costs $340-$580 for full rebuilds of the mortar wash, with partial repairs starting at $280 when damage is caught early. This is where Bangor’s climate hits hardest. The Kittatinny Ridge freeze-thaw cycle opens hairline cracks every winter, and by spring they’re wide enough to stick a pencil in. Water gets in, freezes, expands, and the crown starts shedding chunks into the flue.
Original coal-era chimneys in Bangor rowhouses are frequently unlined or have crumbling terra cotta flues that no modern appliance was ever vented for. A new cap on a failed liner just traps moisture and creosote. We won’t do it. Crown repair without inspecting the flue below is guesswork, and we don’t guess. The camera goes down first. The photos come back. Then we talk about what the crown actually needs.

Crown Coating
Crown coating in Bangor runs $180-$320 and is the best value for crowns with surface cracking but intact structural integrity. We use HeatShield CrownCoat, a flexible refractory compound that bridges hairline cracks and sheds water without the brittle failure of standard cement washes. It’s not a substitute for a crown that’s already spalling or separating from the brick below. But on a Bangor chimney where the crown is basically sound but weather-checked, coating adds years of life at roughly half the cost of rebuild.
We apply it in weather-appropriate conditions, which in Bangor means planning around the freeze-thaw window. Late spring through early fall is ideal. A coating applied to a damp or frozen crown will fail by February, and we don’t do work we can’t stand behind. The 90-Day Done Right Promise applies to coating jobs same as everything else. Done right, and we stand behind it.

Trusted Brands We Service in Bangor
We stock caps, crowns, and flashing materials from HeatShield, Gelco, and Olympia Chimney, with Famco hardware for custom fits. These aren’t builder-grade substitutes from the wholesale club. They’re professional-grade products rated for the temperature cycling and wind exposure that Bangor chimneys face. We keep common sizes in stock for faster turnaround on standard jobs, and we can fabricate custom multi-flue caps for the borough’s irregular flue configurations. Most Bangor homeowners get their cap or crown job completed in a single visit once we’ve done the camera inspection and agreed on scope.
Common Chimney Cap & Crown Problems We See in Bangor Homes
- Slate-to-brick step-flashing failures divert roof water into the crown and flue, spalling brick and eroding mortar long before the cap itself wears out. This is the hidden failure mode in Bangor. The slate roof looks fine. The cap looks fine. But water is tracking down behind the flashing and rotting everything from the inside.
- Freeze-thaw spalling on crown mortar opens cracks that widen every winter. Bangor’s position in the Kittatinny Ridge foothills means more freeze-thaw cycles than lower-elevation towns. Wind funneling along Blue Mountain drives rain and snow into those cracks, accelerating the damage.
- Original terra cotta flues deteriorating beneath intact crowns. The crown looks decent from the roofline, but the flue liner below has cracked from decades of thermal shock. A cap replacement alone traps moisture in the flue and makes the liner problem worse. Camera inspection catches this. Visual inspection from the roof does not.
- Improperly converted coal fireboxes venting into unlined flues. The crown and cap were never designed for the higher moisture content of wood combustion. Creosote condenses on the cool brick, the crown absorbs the runoff, and the mortar wash fails prematurely. We see this pattern constantly in Bangor’s converted worker cottages.

FAQs - Chimney Cap & Crown in Bangor
Failed step-flashing at the slate-to-brick junction is likely sending roof water straight into your crown, where freeze-thaw cycling from Blue Mountain winds opens cracks faster than the mortar can handle. The slate roof itself is fine, but decades of repairs by roofers unfamiliar with slate have left gaps that channel water behind the masonry. We investigate this with a camera and document it with photos before recommending crown work. Call (610) 609-7634 for a free estimate.
Yes. A cap on a failed flue liner traps moisture and accelerates deterioration you can’t see from the roof. Our Level-2 camera inspection shows you the condition of the terra cotta or unlined brick below the crown. We don’t sell caps without this step. The $89 inspection fee is waived when you book a repair. Photos you can see, a plain-English verdict.
The crown is the mortar or concrete wash that seals the top of your chimney structure; the cap is the metal cover that sits above it to keep rain and animals out of the flue. In Bangor, we often find the crown failing while the cap looks fine, or water entering from bad flashing has destroyed both. Camera inspection and roofline photos tell us which is which. We explain what we found before we quote any work.
It depends on whether the flue was properly lined for wood combustion and whether the crown has been maintained since the conversion. Wood produces more moisture and creosote than coal did, and an unlined flue with a deteriorating crown is a fire and carbon monoxide hazard. We inspect with a camera, show you the photos, and tell you plainly what’s safe and what needs attention. Some issues can wait. Others can’t. We’ll be straight about which is which.
Bangor’s combination of century-old coal-era chimneys, original slate roofs with botched flashing repairs, and aggressive Kittatinny Ridge freeze-thaw cycling creates a perfect storm for mortar failure. Easton and Stroudsburg see some of this, but not at the frequency or scale we encounter in Bangor’s dense concentration of quarry-era housing. The good news: it’s fixable, and caught early, it’s far less expensive than rebuilding. Call (610) 609-7634 and we’ll show you exactly what’s happening in your flue.
