Fast, Reliable Chimney Cap & Crown Across Allentown
A properly fitted chimney cap and intact crown in Allentown typically runs $280-$750 depending on the job, and our Chimney Cap & Crown technicians complete most repairs in a single visit. We’ve been driving to Allentown since 1984, and we know the difference between a West End twin home chimney and a South Side rowhouse stack. Call (844) 803-1545 - a live person answers, day or night.
Allentown’s brick rowhouses and semi-detached twins, built heavy between 1900 and 1945, carry masonry chimneys that were never designed for today’s heating equipment. The oversized flues, soft older brick, and shared party-wall stacks common in 18103 and the center city ZIP codes create cap and crown problems you won’t find in newer Lehigh Valley construction. Water gets in through cracked crowns. Draft pulls backward when northwest winds funnel down the valley. Squirrels nest in flues left open after a cap rusts through. We’ve fixed thousands of them.
Why Hearthstone Chimney Co. Is Allentown’s Preferred Chimney Cap & Crown Company
We’ve worked in Allentown for over 42 years. Russell Haines started this company in 1984, and we’ve sent trucks to the South Side, the West End, and up toward Trexler Park ever since. That longevity means something in a city where contractors come and go. We’re not a chain sending kids with a truck wrap. We’re a company that plans to be here in thirty more years, and we act accordingly.
Our technicians are background-checked, uniformed, and trained to document every inspection with photos you’ll see and a plain-English verdict you’ll understand. Most cap and crown jobs in Allentown finish in one visit because we stock the right materials - Gelco and Olympia Chimney caps in common sizes, HeatShield crown coating for the spalled concrete we see on center-city chimneys - and we measure before we drive.
Calls reach a live person 24 hours a day, 7 days a week. No voicemail, no callback queue. When water’s pouring through your crown into the flue during a February freeze-thaw cycle, that matters.
Our 90-Day Done Right Promise covers every job in writing. If it’s not right, we make it right. No paperwork, no arguing. That’s the Keystone Standard.
Our Chimney Cap & Crown Services in Allentown
Cap Installation
New cap installation in Allentown runs $280-$450 for a standard single-flue galvanized or stainless unit, $480-$750 for multi-flue or custom-fit models on the larger rowhouse chimneys common in 18104. We measure the flue tile, check the crown condition beneath, and install a cap that vents properly without trapping moisture. On South Side party-wall stacks, we verify which flue serves which unit before we seal anything - a step the one-truck operators skip.
Cap Replacement
Most caps we replace in Allentown have rusted through, blown off in a Lehigh Valley windstorm, or been torn loose by raccoons. Replacement costs $250-$550 depending on flue count and material. We remove the old hardware, inspect the crown for hidden water damage, and install a new cap with proper clearances. If your flue is oversized for a modern gas insert - common in pre-WWII Allentown homes - we’ll tell you straight and discuss whether a Chimney Liner & Rebuild in Allentown makes sense before you spend money on a cap alone.
Crown Repair
Crown repair in Allentown typically costs $350-$650. The freeze-thaw cycling here is brutal on poured concrete crowns, especially the thin, poorly sloped originals on center-city chimneys. We cut back deteriorated edges, apply a proper bond coat, and resurface with material rated for Pennsylvania winters. For crowns too far gone, we pour new. Either way, you get photos before and after, and a written warranty.
Crown Coating
Crown coating with HeatShield or equivalent professional-grade sealant runs $280-$480 in Allentown. This is preventive work - best done when the crown has minor cracking but hasn’t started spalling chunks into the flue. We clean the surface, fill hairline cracks, and apply a flexible, breathable coating that moves with the masonry through freeze-thaw cycles. It’s not a cure for a crown that’s already crumbling, and we’ll tell you if you’re past the point where coating helps.

Trusted Brands We Service in Allentown
We install and service caps and crowns using professional-grade materials from brands that hold up in Lehigh Valley weather. Gelco stainless caps resist the salt and acid rain that accelerate rust on cheaper hardware. Olympia Chimney supplies multi-flue covers that fit the broad, shared stacks on Allentown’s older twins. For crown coating and repair, we use HeatShield and Famco products rated for the thermal cycling these chimneys endure. We stock common sizes locally, so most Allentown customers don’t wait for special orders. The number on your estimate is the number on your invoice - no surprises when the truck shows up.
Common Chimney Cap & Crown Problems We See in Allentown Homes
- Spalled concrete crowns from freeze-thaw damage. Allentown’s position in the Lehigh Valley basin funnels cold northwest winds across chimney tops all winter. Water penetrates hairline cracks, freezes overnight, and pops off concrete in sheets. By March, we’ve replaced dozens of crowns in 18103 and 18105 that were intact in October.
- Rusted-through galvanized caps on pre-WWII flues. The original caps on Allentown’s rowhouse chimneys were often thin galvanized steel, sometimes nothing more than a terra-cotta flue tile with a brick across the top. After eighty years, they’re holes with edges. We replace them with stainless or copper that outlasts the next generation of homeowners.
- Improperly sized caps on oversized flues. Coal-era chimneys in Allentown’s center city and South Side frequently measure 8×12 inches or larger - far too big for modern gas appliances. A cap that fits the flue tile but doesn’t address the draft problem is a band-aid. We flag this during inspection and explain your options without pressure.
- Shared-stack liability on party-wall chimneys. On tight South Side blocks, one masonry stack may serve three homes through separate flues. A cracked crown or missing cap on your side can funnel water, debris, or combustion gases into a neighbor’s system. We document the stack condition and note any party-wall concerns in your written report.
