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 driving the back roads of the Slate Belt for over 42 years, and Wind Gap sits in a spot that punishes chimneys differently than anywhere else in Northampton County. The borough’s namesake dry gap in Blue Mountain funnels northwest winds straight through town with a force you don’t feel five miles south in Nazareth or Bath. That wind finds every weakness in a cap, every hairline crack in a crown, every screen mesh that’s a half-inch too large. We’ve replaced caps on Sullivan Trail homes that looked perfect from the driveway and found crowns on Broadway Street chimneys crumbling from freeze-thaw cycles that Easton simply doesn’t see. Our technicians are background-checked, uniformed, and trained to work around the slate roofs common in this part of the Slate Belt. Dispatch and scheduling are coordinated from our Philadelphia office, but crews serve Wind Gap locally with no-hassle upfront pricing - the number on the estimate is the number on the invoice.
Why Hearthstone Chimney Co. Is Wind Gap’s Preferred Chimney Cap & Crown Company
Wind Gap homeowners know the difference between a company that passes through and one that knows the ridge. We’ve worked on pre-WWII houses near the Wind Gap park, mid-century ranches off Route 512, and converted farmsteads up toward the mountain base. Our reviews from Wind Gap customers consistently mention the same things: we show up when we say, we explain the camera footage in plain English, and we don’t invent problems.
Our response time to Wind Gap is typically same-week during the shoulder seasons, and we prioritize crown emergencies - active water intrusion, visible spalling, or cap blow-off - because we understand how fast Blue Mountain weather turns a small crack into a saturated wall. The 90-Day Done Right Promise covers every cap and crown job in writing: if it’s not right, we make it right, no paperwork and no arguing. That’s the Keystone Standard, and it’s how we’ve operated since 1984.
Russell Haines built this company on the K.E.Y.S. code - Krafted right, Every time, Your home first, Standing behind it - and that still governs how we treat every Wind Gap chimney. Live person answers the phone. Photos you can see. A verdict you can understand.
Our Chimney Cap & Crown Services in Wind Gap
Cap Installation
New cap installation in Wind Gap demands more than matching flue dimensions. The wind funnel through Blue Mountain means standard mesh screens often clog with ridge debris within a season. We size caps with taller screened skirts for north- and west-facing flues, and we source professional-grade materials from Gelco and Famco that withstand sustained 40-plus mph gusts common here. A typical single-flue cap installation in Wind Gap runs $340-$520, including inspection and fitting. Most jobs complete in one visit.
Cap Replacement
Cap replacement is our most common call in Wind Gap, and for a reason specific to this ridge town. On a pre-WWII house near the Wind Gap park, we pulled a Famco cap off a west-facing flue that looked fine from the driveway, and it was packed solid with pine needles and nesting material blowing in off the ridge. The flue behind it was an unlined stack built for coal and never relined when the appliance switched to gas, so the oversized clay tile was wet and the crown mortar was spalling from freeze-thaw. We set a new multi-flue cap with a taller screened skirt, coated the crown with Gelco, and showed the homeowner the camera footage of the flue walls before recommending anything. Cap replacement in Wind Gap typically runs $280-$480 for standard sizes, $620-$890 for multi-flue setups.
Crown Repair
Crown repair in Wind Gap addresses a failure mode you won’t find in the Lehigh Valley floor. Sitting at the base of Blue Mountain’s ridge, Wind Gap accumulates significant snow load along the north-facing slope, accelerating mortar joint freeze-thaw deterioration faster than Valley-floor towns. We see crowns on Broadway Street and Sullivan Trail homes with spalling that penetrated to the brick course below in five years, not fifteen. Our crown repair process includes removing loose material, applying proper bonding agents, and finishing with a slope that sheds water and snow. Typical crown repair in Wind Gap: $420-$680.
Crown Coating
Crown coating is preventive medicine for Wind Gap chimneys, and we recommend it aggressively - but only where camera inspection shows the crown structure is sound underneath. We apply Gelco CrownCoat, a professional-grade flexible coating that bridges hairline cracks and sheds water without trapping moisture. On a sound crown, this extends service life by years. On a crown that’s already structurally compromised, coating is a waste of money, and we’ll tell you so. Crown coating in Wind Gap runs $340-$520 depending on crown size and accessibility. We won’t sell it without showing you the inspection photos first.
Multi-Flue Cap
Multi-flue caps solve a specific Wind Gap problem: coal-era chimneys with multiple flues in a single stack, common in pre-WWII Slate Belt construction. These chimneys were built oversized for coal appliances, then converted to oil or gas without relining, leaving flues that draft poorly and catch debris from every direction. A multi-flue cap covers the entire chimney top with a single screened structure, eliminating the gaps between individual caps where Blue Mountain wind drives needles and leaves. Multi-flue cap installation in Wind Gap: $890-$1,400.
Custom Cap
Custom caps serve Wind Gap’s non-standard flues - oversized square clay tiles, rectangular oil-vent flues, or chimneys with odd projections from decades of modifications. We fabricate to measurement from stainless or copper, with mesh sizing calibrated to block pine needles while maintaining draft. Custom work starts at $720 and scales with material and complexity. Every custom order includes a field template before fabrication.

Trusted Brands We Service in Wind Gap
We install and service professional-grade chimney caps and crowns from Gelco, Famco, and Olympia Chimney - brands that hold up to Blue Mountain wind and Slate Belt freeze-thaw without the callbacks we’ve seen from builder-grade alternatives. We stock common sizes and screen configurations for Wind Gap’s typical flue dimensions, which means most cap replacements don’t wait on shipping. For crown coating, we use Gelco CrownCoat exclusively - it’s the product we’ve trusted through fifteen Pennsylvania winters. When a Wind Gap homeowner needs a part we don’t have on the truck, our Philadelphia office coordinates next-day delivery so we’re not making multiple trips up Route 512. Done right, and we stand behind it.
Common Chimney Cap & Crown Problems We See in Wind Gap Homes
- Wind-funnel downdraft and backdraft on north- and west-facing flues. The dry gap in Blue Mountain accelerates northwest winds directly into these flues, driving smoke and moisture back into the smoke chamber instead of up the stack. A properly sized cap with adequate draft clearance - not just any cap off the shelf - fixes this.
- Caps that appear intact from the ground but are packed with Blue Mountain debris. Wind Gap’s geographic wind funnel loads north- and west-facing caps with pine needles, leaf litter, and bird nesting material even when the cap structure looks sound. This blocks draft, traps moisture, and accelerates flue deterioration. We find this on Sullivan Trail, on Broadway, up toward the ridge - it’s a pattern that doesn’t show in Bangor or Pen Argyl.
- Freeze-thaw spalling on chimney crowns along the north-facing slope. Snow load and ridge exposure eat mortar joints faster here than in Valley-floor towns. The crown cracks, water penetrates, freeze-thaw widens the cracks, and suddenly you’re looking at brick repair below the crown line. Crown coating on a sound crown prevents this; crown repair addresses it once spalling starts.
- Unlined or oversized clay flues venting gas appliances. Wind Gap’s coal-era housing stock left chimneys built for solid fuel, then converted to oil or gas without relining. The oversized flue cools too fast, condenses moisture, and combines with debris intrusion through inadequate caps to produce saturated, deteriorating systems. We document this with camera footage and explain what needs immediate attention versus what can be monitored.

FAQs - Chimney Cap & Crown in Wind Gap
Wind Gap sits at an actual dry gap in Blue Mountain that funnels northwest winds directly through the borough, carrying pine needles and leaf debris from the ridge slope straight into north- and west-facing flues. Nazareth sits on the Lehigh Valley floor, sheltered from this accelerated wind channel, so caps there don’t see the same debris loading. We solve this with taller screened skirts and finer mesh on Wind Gap caps, sized to the specific wind exposure. Call (610) 609-7634 for an exact quote - estimates are free.
Not necessarily, but you need a camera inspection to know. The oversized flue common in Wind Gap’s coal-era housing cools too quickly with modern gas appliances, causing condensation that combines with debris intrusion to accelerate deterioration. A new cap stops the debris, but if the flue walls are already saturated or the clay tile is cracked, relining becomes the priority. We show you the camera footage and explain what’s urgent versus what can wait. No recommendation without evidence you can see. Call (610) 609-7634 to schedule.
Wind Gap’s position at the Blue Mountain base means more snow accumulation and longer freeze-thaw cycling on north-facing exposures than Valley-floor towns like Easton or Bethlehem. Water enters crown hairlines, freezes, expands, and spalls mortar within seasons rather than decades. Crown coating on a structurally sound crown prevents this; once spalling starts, repair is required. We determine which category you’re in with camera inspection, not guesswork. Call (610) 609-7634 for a free evaluation.
Slate roofs are common in Wind Gap’s Slate Belt housing stock, and our technicians are trained to work around them without breakage. We use ladder access and roof brackets where possible, distribute weight across multiple points, and replace any slate we disturb - though that’s rare with proper technique. We carry the insurance and bonding to cover the unexpected, but more importantly, we carry the experience to avoid it. Your roof stays intact. Call (610) 609-7634 to discuss access for your specific chimney.
Yes, specifically in Wind Gap. The Blue Mountain wind funnel creates downdraft conditions on north- and west-facing flues that push smoke backward into the smoke chamber, especially during northwest weather events. This happens with properly functioning fireplaces because the cap and flue configuration aren’t matched to the local wind pattern. A properly sized cap with adequate draft clearance, sometimes combined with flue extension, typically resolves it. We diagnose this with smoke testing and visual inspection, not speculation. Call (610) 609-7634 - estimates are free.
