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 know Wind Gap. Our crews work the borough’s late-19th and early-20th century housing stock regularly - the modest worker homes and vernacular colonials off Chestnut Street, the older masonry along Broadway, the post-war builds up toward the mountain ridge. These chimneys have seen decades of coal and wood burning, and they sit in one of the most punishing wind corridors in Northampton County. If you’re seeing ceiling stains, smoke rollback on northwest-wind nights, or brick faces flaking off your chimney, call (610) 756-1504. A live person answers, 24 hours a day.
Why Hearthstone Chimney Co. Is Wind Gap’s Preferred Chimney Repair Company
We’ve been serving Northampton County communities for over 42 years. Our Chimney Repair team understands what the Blue Mountain notch does to chimneys here - the sustained directional wind load, the accelerated freeze-thaw cycling, the pattern of wind-scoured mortar joints we simply don’t see at this frequency in sheltered towns like Bath or Nazareth. That local knowledge means faster diagnosis and repairs that actually last.
Our technicians are background-checked, uniformed, and arrive with professional-grade materials from brands like DuraFlex, HeatShield, and Copperfield. Most repairs are completed in a single visit. You’ll get photos you can see, a plain-English verdict, and no-hassle upfront pricing - the number on the estimate is the number on the invoice. Every job is backed by our 90-Day Done Right Promise in writing: if it’s not right, we come back, no arguing, no paperwork games.
Calls are answered by a live person, 24/7. Not voicemail. Not a callback queue. Scheduling is coordinated from our Philadelphia office, and our Chimney Repair in Wind Gap crews are local to the Lehigh Valley.
Our Chimney Repair Services in Wind Gap
Chimney Rebuilding
Some Wind Gap chimneys - especially the original masonry on pre-1950s homes - have reached the point where repointing isn’t enough. The combination of aging coal-fire clay flue tiles, wind-scoured mortar, and decades of freeze-thaw damage leaves the structure compromised. We rebuild partial chimney sections using professional-grade materials, matching existing brick courses and installing proper Chimney Liner & Rebuild - Wind Gap components from Olympia Chimney or DuraFlex. A full rebuild in Wind Gap typically runs $3,200-$6,800 depending on height and access; partial rebuilds often fall between $1,800-$3,500.
Flashing Repair
The gap in Blue Mountain doesn’t just channel wind - it drives rain and sleet against chimney flashings with sustained force. We see lifted counter-flashing, corroded step flashing, and sealant failures that show up as brown ceiling stains after storms. Our flashing repairs use copper or heavy-gauge aluminum with proper integration into existing roofing. Most Wind Gap flashing repairs cost $450-$1,200. We document the damage with camera photos before touching anything, so you see exactly what failed and why.
Chimney Waterproofing
Wind Gap’s wind-driven precipitation pushes water deeper into masonry than in sheltered Lehigh Valley towns. Standard waterproofing sprays often fail within a season here. We use professional-grade, vapor-permeable sealers from HeatShield and Copperfield - formulated to repel liquid water while letting trapped moisture escape. Application runs $680-$1,400 for most residential chimneys in the borough, and we always repair spalled brick and compromised mortar before sealing. Sealing damaged masonry traps water inside. We don’t do that.
Mortar Repointing & Tuckpointing
The worker homes off Chestnut Street and the older builds along Broadway share a common problem: original lime mortar weakened by coal and wood combustion acids, then scoured by decades of wind through the mountain notch. We grind out failed joints to proper depth and repoint with mortar matched to the original composition - not Portland-heavy mixes that accelerate deterioration of soft historic brick. Typical repointing in Wind Gap runs $850-$2,400 depending on accessibility and joint condition.
Spalling Brick Repair
Freeze-thaw cycling hits Wind Gap harder than Pen Argyl or Bath because the wind gap accelerates temperature swings at the chimney crown. Water enters micro-cracks, expands, and pops brick faces off in sheets. We remove spalled units, install proper drainage details, and replace with matching brick when possible. Spalling repair without structural rebuild typically costs $650-$1,800 in this market.

Trusted Brands We Service in Wind Gap
We don’t use builder-grade substitutes. Our trucks carry professional-grade materials from DuraFlex, HeatShield, Copperfield, and Famco - brands that hold up to Wind Gap’s specific wind and weather load. That means faster turnaround for you: no waiting on special orders for standard repairs. When we recommend a wind-directional cap or a crown rebuild with HeatShield’s refractory system, it’s because we’ve installed those products in this borough before and know they survive the notch’s sustained northwest exposure.
Common Chimney Repair Problems We See in Wind Gap Homes
- Wind-warped or displaced standard chimney caps. The venturi effect through Blue Mountain subjects caps to constant lateral wind load that round, fixed models aren’t engineered for. We regularly find caps that have rotated, lifted, or had their mesh screens torn away - opening the flue to direct rain and animal entry.
- Crown cracks from accelerated freeze-thaw. Wind Gap chimneys experience more rapid temperature cycling than sheltered Lehigh Valley properties. Hairline crown cracks widen each winter, eventually channeling water straight into the chimney structure and down to the attic framing.
- Wind-scoured mortar joints revealing hidden flue gaps. As mortar erodes between courses, gaps open between the clay flue liner and surrounding brick. Creosote accumulates in these voids, creating a hidden fire hazard that standard visual inspection misses - one reason we always run a Level-2 camera.
- Flashing failure after wind-driven rain events. The sustained directional pressure forces water behind improperly seated flashing, especially on older homes where original step flashing was never properly integrated with counter-flashing. The first sign is often a brown stain on the ceiling below the chimney.

FAQs - Chimney Repair in Wind Gap
Wind Gap’s position in the notch eroded through Blue Mountain creates a venturi effect that funnels prevailing northwest winds straight through the borough, subjecting chimneys to sustained, directional wind loads that scoured mortar joints and cracked crowns over decades - a pattern far less pronounced in sheltered Lehigh Valley towns like Nazareth or Pen Argyl. Standard round caps aren’t rated for constant lateral load; they warp, rotate, or lift, opening the flue to water and debris. We were called out to a circa-1920s worker’s home off Chestnut Street where the homeowner reported smoke rollback on every cold northwest-wind night. Our tech found the original round chimney cap had been wind-warped and the crown had multiple hairline cracks from years of freeze-thaw cycling accelerated by the gap’s wind channel. We rebuilt the crown, repointed the spalled mortar joints, and installed a Chimney Cap & Crown - Wind Gap 180-degree draft-inducing cap oriented to the prevailing NW flow - the downdraft complaints stopped immediately. Call (610) 756-1504 if you’re seeing similar symptoms.
Most ceiling stains below a chimney indicate compromised flashing, and Wind Gap’s wind-driven rain makes this more likely than in sheltered towns. The sustained pressure forces water behind lifted counter-flashing or corroded step flashing, then it tracks along framing until it exits through your ceiling drywall. We verify with a camera inspection of the chimney exterior and attic space when accessible - photos included, no guesswork. Flashing repair in Wind Gap typically runs $450-$1,200. Call (610) 756-1504 for a free inspection before the next storm.
Annually, without exception - and we recommend inspection in late summer or early fall, before the first heating season burn. Wind Gap’s accelerated freeze-thaw cycle and wind-scour mean damage progresses faster than in more sheltered communities. An annual Level-2 inspection catches crown cracks, mortar deterioration, and cap displacement before winter wind and precipitation compound them. The $89 Seasonal Tune-Up includes full inspection and Chimney Cleaning & Sweep - Wind Gap service. Call (610) 756-1504 to schedule.
A wind-directional or 180-degree draft-inducing cap, properly oriented to the prevailing northwest flow, resolves most Wind Gap downdraft complaints. Standard round or hooded caps often worsen the problem by creating turbulent eddies in sustained directional wind. We install caps from Famco and Copperfield rated for lateral wind load, with proper mesh screening that resists tearing. Installation typically costs $380-$750. Call (610) 756-1504 for sizing and orientation assessment.
Yes - most crown damage in Wind Gap is repairable without rebuilding the chimney structure. We remove deteriorated concrete to sound substrate, form a proper slope for drainage, and pour a new crown with reinforced professional-grade refractory material or apply HeatShield’s crown resurfacing system. Rebuilds run $1,200-$2,800; resurfacing for less severe cracking falls at the lower end. We only recommend full rebuild when the chimney structure itself is compromised - and we’ll show you the camera evidence so you can decide with confidence. Call (610) 756-1504 for a free evaluation.
