Why Hearthstone Chimney Co. of Philadelphia Is Pennsport’s Preferred Chimney Cap & Crown Company
Pennsport homeowners know their chimneys weren’t built for modern life. These 1880-1930 brick rowhomes were designed for coal heat, converted later to gas or oil, and many still run oversized flues without proper relining. We’ve documented thousands of these systems with our Level-2 camera inspections, and we explain what we find in plain English, with photos you can see yourself.
Our reputation in Pennsport is built on showing up when we say we will and standing behind the result. The 90-Day Done Right Promise means if it’s not right, we come back. In writing. No arguing. Carl Bridwell started this company in 1984, and we’ve been answering the phone with a live person ever since, not a voicemail queue.
Most of our Pennsport calls come from homeowners who’ve lived in their houses for twenty-plus years, or from new buyers who just discovered what the previous owner hid. Either way, we give upfront pricing before any work begins. The number on the estimate is the number on the invoice.
Our technicians are background-checked and uniformed, and they complete most cap and crown jobs in a single visit. We carry professional-grade materials from DuraFlex, Famco, and Copperfield, so we’re not waiting on parts while your flue stays open to the weather.
Our Chimney Cap & Crown Services in Pennsport
Crown Repair
Crown repair is the most common call we get in Pennsport, and for good reason. Philadelphia’s freeze-thaw cycles, amplified by the Delaware River’s persistent moisture, spall the mortar crowns on century-old brick stacks until the flue top is essentially open to the sky. A typical crown repair in Pennsport runs $450-$720. We demo the damaged crown, pour a new concrete crown with proper slope and a 2-inch overhang, and seal it with a waterproofing treatment rated for our climate. On a 1910 rowhome on Tasker Street, we found a crumbled terra-cotta crown that had let rain pool around the flue tile, spalling the masonry for two feet down. We demoed the old crown, installed a new poured-in-place concrete crown with a 2-inch overhang, and topped it with a stainless steel multi-flue cap from DuraFlex to vent the homeowner’s gas furnace and re-opened fireplace safely.
Crown Coating
For crowns with minor cracking but sound structure, crown coating buys years of protection at lower cost. In Pennsport, where the river air keeps masonry perpetually damp, we apply flexible, breathable coatings that move with freeze-thaw expansion instead of cracking again the first winter. Crown coating in Pennsport typically runs $340-$520. We only coat crowns that pass our camera inspection, because trapping moisture behind a coating on already-saturated masonry accelerates damage. This is especially critical on Pennsport’s shared-wall chimneys, where water infiltration can travel horizontally into neighboring flues.
Multi-Flue Cap Installation
Most Pennsport rowhomes vent multiple appliances through a single chimney chase, often a gas furnace and a reopened fireplace sharing the same flue or adjacent flues. A multi-flue cap covers the entire crown, protecting all flue openings with one integrated unit. Multi-flue cap installation in Pennsport runs $380-$650 depending on chase dimensions and whether we need to extend or modify the flue terminals. We size and fabricate these on-site from stainless steel DuraFlex components, because Pennsport’s narrow roof access and shared-wall configurations rarely accommodate off-the-shelf sizes.
Cap Replacement
Single-flue cap replacement is straightforward when the crown beneath is sound. In Pennsport, it rarely is. We inspect the crown before quoting any cap replacement, because a new cap on a crumbling crown is money wasted. Cap replacement alone runs $180-$340; when paired with crown repair, we bundle the work. We stock galvanized, stainless, and copper caps from Famco and Copperfield, and we match the cap to your venting configuration, not just what we have on the truck.

Trusted Brands We Service in Pennsport
We work exclusively with professional-grade materials from DuraFlex, Famco, and Copperfield, no builder-grade substitutes that fail in three seasons. For Pennsport’s harsh crown environment, we specify stainless steel over galvanized unless the homeowner specifically requests copper for historical compatibility. We keep common multi-flue cap sizes and crown-forming materials stocked locally, so most Pennsport jobs don’t wait on delivery. When we quote a job, we’re quoting work we can complete, not work we’ll start and then order parts for.
Common Chimney Cap & Crown Problems We See in Pennsport Homes
- Sealed flues reopened by new owners. Pennsport’s rapid gentrification has sent new buyers into rowhouses where mid-century residents bricked up fireplaces and forgot them. When new owners reopen the damper, they often find missing or shattered clay-tile liners behind it, with a crown that’s been crumbling unseen for decades. We inspect before any use.
- Freeze-thaw spalling on river-exposed masonry. The Delaware River’s moisture-laden air keeps Pennsport chimney crowns saturated through winter. When temperatures drop below freezing, water in the mortar expands, flakes off surface material, and exposes fresh porous masonry to more water. By March, we’re rebuilding crowns that were intact in October.
- Shared-wall water migration. Pennsport’s brick rowhomes share party-wall chimneys, so a compromised cap or crown on one side can send water and debris into the neighbor’s flue. We coordinate with adjacent homeowners when possible, because crown replacement on a shared chase is almost always a two-home job.
- Mid-century abandonment, modern rediscovery. Bricked-up fireplaces with no cap maintenance for fifty years leave crowns that look intact from the street but are structurally failed. We camera-inspect every reopened flue and rebuild crowns before any venting resumes.

FAQs - Chimney Cap & Crown in Pennsport
No, you generally cannot replace just your side’s crown on a shared party-wall chimney, because the crown is a single continuous structure capping both flues. We coordinate with both homeowners, inspect both flues with our Level-2 camera, and quote the rebuild as a joint project when possible. The cost typically splits $450-$720 per side for a full crown rebuild with integrated multi-flue cap. If your neighbor won’t participate, we can sometimes install an internal flue-sealing solution on your side, but the crown itself must be addressed as one unit. Call (866) 580-4069 and we’ll walk through your specific chase configuration.
The cap is probably missing entirely, and the crown is likely crumbled or severely cracked from decades of zero maintenance. Mid-century owners who bricked up fireplaces rarely invested in cap or crown upkeep, because they weren’t using the flue. Before you light any fire or connect any appliance, we need to camera-inspect the flue, assess the liner condition, and rebuild the crown if needed. This is standard practice on every Pennsport sealed-flue call we get. Schedule an inspection at (866) 580-4069.
Pennsport’s proximity to the Delaware River keeps crown masonry saturated with moisture-laden air, so when temperatures drop below freezing, that water expands and fractures the mortar surface. Each cycle removes a thin layer of material, progressively exposing deeper porous masonry. By late winter, we’ve rebuilt dozens of crowns that were intact in fall. A properly sloped concrete crown with waterproofing treatment and an overhanging cap is the only lasting defense in this climate.
A multi-flue cap is a single stainless steel cover that protects multiple flue openings on one chimney chase, with screening to block animals and debris. You need one if your Pennsport rowhome vents a furnace and fireplace through the same chase, or if you have adjacent flues that a single cap can protect more reliably than separate units. Most Pennsport shared-wall chimneys benefit from multi-flue caps because the integrated design seals better against wind-driven rain off the river. Installation runs $380-$650.
The crown itself is concrete, not brick, so we match slope and overhang proportions to your original design rather than brick color. If your chase has decorative brick corbelling below the crown, we preserve it during rebuild. For homeowners who want copper caps that weather to a green patina matching Pennsport’s historic architectural details, we stock Copperfield copper multi-flue caps. We’ll show you samples during the estimate. Call (866) 580-4069 to see options.
