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.

AfterFast, Reliable Chimney Cap & Crown Across East Allen
Chimney cap and crown repair in East Allen typically runs $280-$890 depending on whether you’re sealing a single crown crack or fitting a custom multi-flue cap across a three-flue farmstead stack. Most East Allen jobs are completed in one visit, and our crews are already working the Lehigh Valley corridor daily.
We know East Allen’s chimneys. The township’s mix of pre-1940 Pennsylvania German bank farmhouses and 1990s-2010s tract subdivisions creates two completely different cap and crown failure patterns, sometimes on the same road. Our Chimney Cap & Crown technicians carry both masonry crown materials for soft-mortar fieldstone stacks and stainless multi-flue caps for zero-clearance prefab units. Dispatch is coordinated from our Philadelphia office, but our trucks are already serving Northampton County every day of the week. Call (610) 632-1394 and you’ll reach a live person, 24 hours a day.
Why Hearthstone Chimney Co. Is East Allen’s Preferred Chimney Cap & Crown Company
We’ve been answering calls with a live person for over 42 years. That matters in East Allen, where many of our customers have lived in the same farmhouse for thirty years and remember the last contractor who never called back.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict. On a converted bank farmhouse off Weaversville Road, we pulled a squirrel nest from a summer-kitchen flue while replacing a cracked concrete crown on a three-flue stack. The main wood-stove flue serving the homeowner’s primary heat source was lined with first-degree creosote, so we set a DuraFlex liner, sealed the adjacent abandoned flues, and fitted a custom multi-flue cap - one visit, three masonry fixes, and a draft that finally held through a below-freezing night.
Every job is backed by our 90-Day Done Right Promise in writing, no arguing. Our technicians are background-checked and uniformed, and we use professional-grade materials from brands like HeatShield, Gelco, and Olympia Chimney - no builder-grade substitutes. The number on your estimate is the number on your invoice.
Our Chimney Cap & Crown Services in East Allen
Crown Repair
Crown repair is our most common call in East Allen’s older farmsteads. The township’s freeze-thaw cycle funnels Arctic air through the Blue Mountain gaps, and on pre-1940 Pennsylvania German farmsteads those cycles crack the soft-mortar crowns that cap a single multi-flue stack. One cap inspection routinely reveals mortar rot and abandoned-flue hazards on the same call. We grind out damaged concrete, pour a new sloped crown with proper overhang and drip edge, and seal it with a flexible waterproof coating that moves with the masonry through East Allen’s hard winters. Typical crown repair in East Allen runs $340-$620.
Multi-Flue Cap
Multi-flue caps are essential on East Allen’s original farmstead properties, where chimney stacks often served two or three separate flues - a main fireplace, a summer kitchen flue, and a stove flue. Only one flue may still be active, but all three share a single deteriorating cap. A multi-flue cap covers the entire stack with one welded stainless unit, keeping rain and snow out of active and abandoned flues alike. We measure on-site and fabricate to fit your stack’s exact dimensions. Multi-flue cap installation in East Allen typically costs $480-$890.
Custom Cap
Standard caps don’t fit every East Allen chimney. Oversized flues, irregular crown profiles, or decorative chimney pots on restored farmhouses require custom fabrication. We template on-site, specify 304 or 316 stainless depending on your fuel type and exposure, and weld caps that shed Lehigh Valley snow loads without blocking draft. Custom caps in East Allen generally run $520-$950 depending on metal gauge and screen configuration.
Cap Replacement
Builder-grade caps on 1990s-2010s tract homes corrode faster than homeowners expect. East Allen’s wet springs and hard freeze cycles accelerate rust-through on galvanized caps, and once the screen fails, squirrels and starlings move in fast. We replace with stainless or copper caps from Famco and Olympia Chimney, properly sized to the flue with correct clearance. Cap replacement in East Allen usually costs $180-$340.
Crown Coating
For crowns with minor cracking but sound structural integrity, crown coating extends service life five to ten years. We clean and prep the existing crown, then apply a flexible elastomeric sealant rated for freeze-thaw cycling. It’s a square deal for East Allen homeowners who want to defer full crown replacement without risking water infiltration through another Lehigh Valley winter. Crown coating runs $280-$450 in East Allen.

We stock professional-grade materials from HeatShield, Gelco, Olympia Chimney, and Famco - brands that hold up to East Allen’s freeze-thaw abuse, not hardware-store substitutes that rust out in three seasons.

When a custom fabrication is needed, we template on the first visit and return with the finished unit, typically within a week. Done right, and we stand behind it.
Common Chimney Cap & Crown Problems We See in East Allen Homes
- Soft-mortar crowns spalling after hard freezes. East Allen’s position in the Lehigh Valley corridor south of Blue Mountain means sustained below-freezing temperatures that aggressively expand water infiltrating mortar joints. Pre-1940 fieldstone stacks with original soft mortar are especially vulnerable. We see this on rural roads throughout the township every spring.
- Abandoned flues open to the weather. On multi-flue farmstead stacks, homeowners often cap only the active flue and leave summer kitchen or stove flues exposed. Rain and snow enter freely, accelerating liner cracking and creating hidden hazards that a Level-2 inspection routinely uncovers.
- Builder-grade caps failed on tract-home prefabs. The 1990s-2010s subdivisions near Hanoverville Road and beyond feature factory-built fireplaces with metal flue liners that sit unused for years. Their original galvanized caps corrode, screens collapse, and bird or squirrel nests go unseen until draft problems or odors drive a call.
- Single storm losses across multiple flues. High winds funneled through the Appalachian gaps can tear off several caps from one multi-flue stack in a single event. Homeowners discover the damage only when water stains appear on the ceiling below, often weeks later.

FAQs - Chimney Cap & Crown in East Allen
Every 30-45 fires during burning season, or at minimum twice yearly - once in fall before first use, and once in spring after shutdown. East Allen’s rural properties often burn hardwood six months straight, and first-degree creosote can advance to third-degree glaze in a single season of heavy use. Call (610) 632-1394 to schedule - estimates are free.
Pennsylvania German farmhouses were built with separate flues for each heat source - main fireplace, summer kitchen, and cooking stove - all rising through one masonry stack. Only one may be active now, but the abandoned flues still need caps to keep water and animals out. Our multi-flue caps address the whole stack in one unit.
First-degree creosote is dry, flaky soot that brushes off easily - common with dry hardwood and hot fires. Third-degree creosote is a hard, glossy, tar-like glaze that requires rotary removal and is highly combustible. We see both in East Allen: first-degree in well-tended wood stoves, third-degree in fireplaces smoldering wet wood or damped down overnight. A Level-2 camera inspection tells you which you have.
Yes, aggressively. Arctic air masses funnel through Blue Mountain gaps each winter, driving sustained freezes that expand water in mortar joints. East Allen’s wet springs add more moisture to absorb. The result is spalling, cracking, and eventual crown failure that lets water straight into the flue. Annual inspection catches it before the crown is lost.
Most tract-home prefabs have only one flue, so a standard single-flue cap suffices. But if your home was built with a decorative second flue or if a previous owner added a wood-stove insert with its own liner, a multi-flue cap covers both with proper clearance and unified protection against Lehigh Valley wind and snow. We measure and fit on-site.
