Why Hearthstone Chimney Co. Is Wilson’s Preferred Chimney Cap & Crown Company

Wilson homeowners tend to stay put. They’ve owned their houses for twenty, thirty, forty years. They’ve also been burned by contractors who recommended work they couldn’t verify, and they remember it. We don’t operate that way.

Our technicians are background-checked, uniformed, and trained specifically on the shared-stack configurations common in Northampton County’s older boroughs. Most jobs complete in one visit. The price we quote is the price on the invoice.

Our Chimney Cap & Crown Services in Wilson

Custom Cap Installation

Wilson’s party-wall and shared chimneys rarely fit standard big-box caps. On a block of 1920s twins off Spring Garden Street, our tech ran a camera down a shared party-wall stack and found the crown cracked and spalling with missing mortar joints, allowing water to run down the flue and degrade the original clay tile liner. We identified which flue served each unit, then installed a custom multi-flue cap sized to both openings with Copperfield mesh to keep out animals, and coated the crown with a flexible Gelco sealant to stop further water intrusion. Custom fabrication means the cap fits the flue, not the other way around.

Cap Replacement

Old caps rust, warp, or blow off in the Lehigh Valley’s winter wind. In Wilson, we replace more caps that were never properly sized to begin with - installed by roofers or handymen who didn’t account for the flue diameter, the draft requirements, or the shared-stack layout. We measure, we photograph, we fit. A proper cap keeps rain, animals, and debris out while letting exhaust escape. Done right, and we stand behind it.

Crown Repair

The crown is the concrete or mortar slab that seals the chimney top where the flue exits. On Wilson’s early-20th-century masonry, soft lime-based mortar joints erode faster under freeze-thaw cycles, causing the crown to crack and separate from the flue top. Once water enters, it runs down the flue, degrades clay tile, rusts dampers, and stains interior walls. We remove loose material, rebuild the crown to proper pitch and overhang, and seal it against further intrusion.

Crown Coating

Not every cracked crown needs rebuilding. If the structural integrity is sound but the surface is weathered, a professional-grade flexible coating - we use Gelco CrownCoat and similar products - fills hairline cracks and creates a waterproof membrane. This is often the right call on Wilson chimneys where the crown is structurally intact but the Lehigh Valley’s repeated freeze-thaw has opened surface fissures. We’ll show you the camera footage and tell you straight whether coating is sufficient or rebuild is the honest recommendation.

Multi-Flue Cap

Shared party-wall chimneys in Wilson’s tight row-home blocks often serve two separate households with two separate appliances. A single multi-flue cap covers both flues with one integrated unit, properly screened and vented, eliminating the cross-draft problems that let smoke and creosote accumulate unevenly. These require precise measurement and custom sizing - not a stock item from a hardware store.

Trusted Brands We Service in Wilson

We work exclusively with professional-grade materials: DuraFlex stainless liners and components, HeatShield cerfractory resurfacing products, Gelco crown sealants and coatings, and Copperfield chimney caps and screening. We stock common cap sizes and crown coating supplies locally, so Wilson jobs don’t wait on shipping. When a custom cap is needed, we fabricate to spec rather than forcing a near-fit. No builder-grade substitutes. A square deal, no surprises on the bill.

Common Chimney Cap & Crown Problems We See in Wilson Homes

• Crown cracking from freeze-thaw damage. The Lehigh Valley delivers cold, wet winters with repeated freeze-thaw cycles that are particularly destructive to the aging brick and soft mortar found on Wilson’s early-20th-century chimneys - accelerating spalling, joint erosion, and crown cracking. Proximity to the Delaware River corridor adds persistent moisture that speeds efflorescence and masonry deterioration on structures that may not have been repointed in decades.
• Cross-draft problems in shared party-wall stacks. Party-wall shared chimneys create cross-draft problems that let smoke and creosote accumulate unevenly, accelerating first- and second-degree creosote buildup and stressing the cap seal. Determining which flue belongs to which unit is a required step before any cap or crown assessment, something technicians coming from suburban markets frequently miss on their first Wilson job.
• Mismatched flues venting modern appliances. Original clay-tile flues sized for anthracite coal now venting gas inserts or wood stoves have mismatched draft, leading to improper drafting that can push flue gases past a poorly sealed crown or cap. The cap and crown must accommodate the actual appliance and flue combination, not the original 1920s design.
• Water intrusion degrading original clay tile. Once a crown cracks or a cap fails, water runs directly down the flue. On Wilson’s unlined or original clay-tile flues, this accelerates liner deterioration, thins the tile, and can open gaps between flue sections that allow heat transfer to combustible framing. We catch this with camera inspection before it becomes a structural problem.
