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.

Why Hearthstone Chimney Co. Is Hellertown’s Preferred Chimney Repair Company
We’ve worked on chimneys in Hellertown long enough to recognize the borough’s signature problem before we set up the ladder: dual-flue stacks built for coal, converted to oil, then gas, often without proper relining, shared between attached neighbors who may not know their flues connect. That kind of institutional memory matters. It means we check both flues every time, even when you called about one. It means we spot cross-contamination risks that a technician unfamiliar with Hellertown’s housing density might miss.
Our customers here tend to be long-term homeowners, the kind who remember when their street was all Bethlehem Steel families and who want the repair done correctly so their children won’t inherit the problem. The 90-Day Done Right Promise governs every job - Krafted right, Every time, Your home first, Standing behind it - and it’s backed in writing with no arguing. Background-checked, uniformed technicians arrive when scheduled, document the inspection with photos you can see, and explain the verdict in plain English before any work begins. No-hassle upfront pricing means the estimate number matches the invoice number. Period.
Our Chimney Repair Services in Hellertown
Mortar Repointing
The freeze-thaw cycle in the lower Saucon Valley runs long past February, and by March the mortar in a 1920s Hellertown chimney has been through fifty or sixty stress cycles. We grind out deteriorated joints to proper depth and repoint with color-matched, professional-grade mortar formulated for the region’s wet winters and sharp temperature swings. On twin homes off Main Street, we pay particular attention to the party-wall joints where shared stacks take abuse from both sides. Most repointing jobs in Hellertown run $350-$900 for accessible sections, with full-stack work climbing toward $1,800 on taller structures.
Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is nearly universal on pre-1960 Hellertown homes where moisture has penetrated failed crowns or open mortar joints and then frozen. We remove damaged brick, source matching replacements where possible, and rebuild the affected courses with proper bonding and weep details. In the borough’s core neighborhoods, we’ve learned to expect spalling concentrated at the flue partition walls of dual-flue stacks, where temperature differentials between active and dormant flues accelerate moisture movement. Typical spalling repair runs $500-$1,400 depending on height and access.
Chimney Waterproofing
Hellertown’s position in the valley collects cold air drainage and holds moisture against masonry longer than ridge-top properties nearby. We apply vapor-permeable waterproofing agents - never film-forming sealers that trap moisture inside - after repairing any underlying mortar or brick damage. The treatment is particularly valuable on the exposed south and west faces of chimneys in the borough’s tighter street grids, where wind-driven rain hits hard and drying time is limited. Waterproofing typically adds $300-$600 to a repair job, or $450-$800 as a standalone treatment.
Flashing Repair
Step flashing and counterflashing on Hellertown’s older homes often dates to the last roof replacement, which may have been two or three decades ago. We remove corroded or improperly lapped flashing, install new galvanized or copper components with proper integration to the roofing membrane, and seal with high-temperature compounds rated for chimney applications. On the borough’s steeper-pitched roofs - common on the 1920s bungalows - safe access requires proper staging, which we build into every quote. Flashing repair generally runs $400-$950.
Chimney Rebuilding
When deterioration exceeds 30-40% of the stack, partial or full rebuilding becomes the honest recommendation. We’ve rebuilt chimneys from the roofline up on Water Street twins and done full-height reconstructions on detached homes near the Saucon Creek. Every rebuild includes a properly sized liner system - usually DuraFlex stainless steel - and a Chimney Cap & Crown - Hellertown with proper overhang and drip edge. Full rebuilds in Hellertown typically range $2,200-$5,500, with height, access, and liner specification driving the final figure.
Tuckpointing
Where mortar joints are sound but weathered, tuckpointing restores appearance and adds a protective layer without full joint removal. It’s a precision craft, and on Hellertown’s historic-facing homes it preserves the streetscape while sealing out moisture. We match existing mortar color and profile exactly, using techniques appropriate for the era of construction. Tuckpointing runs $450-$1,200 for most Hellertown chimneys.

Common Chimney Repair Problems We See in Hellertown Homes
- Shared-stack cross-contamination in twin and row housing. Original dual-flue chimneys serving both a furnace and fireplace were never designed for the vent pressures of modern gas appliances. When clay tile liners crack, exhaust gases migrate between flues - sometimes into a neighbor’s living space. We inspect both flues and both appliances on every call.
- Freeze-thaw destruction of crowns and mortar. The lower Saucon Valley’s cold air drainage and late-season freeze cycles shatter concrete crowns and open mortar joints by March. Water enters, freezes, expands, repeats. Annual inspection catches this before rebuild territory.
- Improperly sized flues from successive fuel conversions. Coal flues are too large for modern gas; oil conversions often skipped relining entirely. The result is poor draft, excessive creosote, and accelerated liner deterioration. Repair without resizing just relocates the problem.
- Spalled brick at flue partitions. The internal wall separating dual flues takes thermal stress from both sides. In Hellertown’s converted stacks, this partition is often the first masonry element to fail, creating hidden pathways for gases and moisture.

FAQs - Chimney Repair in Hellertown
Because your chimney was built as a dual-flue stack serving both your fireplace and your neighbor’s heating appliance from one masonry structure, and cracks in the shared partition or crown let gases and moisture cross between flues. On a twin home off Main Street in Hellertown, our tech pulled the damper and found the firebox flue clogged with glazed second-degree creosote while the adjacent flue - serving the neighbor’s converted furnace - was venting into the same stack with a cracked clay tile liner. We repointed the shared crown, repaired the spalling brick at the flue partition, and installed a Chimney Liner & Rebuild - Hellertown solution with a DuraFlex liner in the fireplace flue so neither appliance could feed the other. The draft improved immediately and the callback we’d normally expect from a shared-cap setup never came. If you live in attached or twin housing in Hellertown, we inspect both flues every time. Call (610) 632-1394 to schedule.
Repointing is sufficient when mortar joints are eroded but the brick faces are sound and the structural courses are intact; rebuilding becomes necessary when more than 30-40% of the brick is spalled, courses are loose, or the stack leans. Our Level-2 camera inspection and photo documentation show you exactly which condition applies to your chimney. Most Hellertown homes built 1910-1950 are in repointing territory if caught early; delay through a few Saucon Valley winters and the same chimney crosses into rebuild territory. The inspection costs nothing when bundled with repair scheduling. Call (610) 632-1394 and we’ll give you a plain-English verdict you can see for yourself.
Often yes, because the original clay tile liner was sized for coal and is now cracked from decades of incompatible flue gas temperatures and moisture loads after conversion to oil or gas. Repairing the masonry without addressing liner sizing leaves you with a sound stack and a dangerous flue. We use DuraFlex stainless steel liners or HeatShield cerfractory resurfacing depending on the flue’s condition, and we size correctly for your current appliance. The liner work is integrated into our rebuild quotes, not tacked on as a surprise. Call (610) 632-1394 to discuss your specific setup.
Before burning season begins in late September, because the freeze-thaw damage from the previous winter has had all summer to worsen, and because masonry repairs need curing time before sustained heating begins. That said, we repair chimneys year-round in Hellertown, including emergency crown and flashing repairs during active leaks. The lower Saucon Valley’s late freeze-thaw cycles into March mean spring inspections often reveal winter damage that should be addressed before the next heating season. Call (610) 632-1394 to book - we’ll tell you honestly if your repair can wait or if it needs immediate attention.
Yes, and the distinction matters for safety. First-degree creosote is flaky, dry, and brushes away readily; second-degree glaze is shiny, hardened, and requires mechanical removal or chemical treatment; third-degree glaze is tar-like, highly combustible, and demands immediate professional intervention. In Hellertown’s coal-converted chimneys, we frequently find glazed deposits where undersized or oversized flues have cooled flue gases below the condensation point. Our Chimney Cleaning & Sweep in Hellertown camera inspection shows you the type and location before we recommend removal method. Call (610) 632-1394 - estimates are free, and we’ll show you exactly what we’re seeing.
