We’ve been driving out to Willow Grove from Philadelphia for over 42 years. We know the postwar neighborhoods off Route 611, the split-levels near Fitzwatertown Road, and the brick colonials around Willow Grove Park. These houses were built in a different era, with chimneys sized for coal and oil, not modern gas appliances. That matters when we’re fitting a cap or rebuilding a crown. The wrong cap on an oversized flue traps condensation. An uncoated crown in Montgomery County’s freeze-thaw cycle won’t last five winters. Our Chimney Cap & Crown team measures twice and solves the actual problem, not just the symptom.

Our Chimney Cap & Crown Services in Willow Grove
Crown Repair
Crown repair is our most frequent call in Willow Grove, and there’s a reason. Montgomery County’s freeze-thaw cycle is aggressive. Water seeps into hairline cracks, freezes overnight, and heaves the concrete apart by spring. Willow Grove sits inland enough to miss the slight moderating effect of the Delaware River, so masonry chimneys here face more repeated freeze-thaw stress than those in closer-in Philadelphia neighborhoods. We remove the damaged crown, pour a new sloped cap with proper overhang and drip edge, and seal it with a professional-grade crown coating. Done right - and we stand behind it.
Custom Cap
Standard caps don’t fit chimneys that have been modified over sixty years. Willow Grove’s 1950s-1970s housing stock was built with coal-chimney dimensions - typically 8×8 or 8×12 clay tiles - which, when repurposed for modern gas appliances, create oversized flues that accelerate condensation and liner decay. A custom cap solves this. We fabricate caps to exact flue dimensions, with proper screening and clearance, using materials from Copperfield and Famco. On a split-level on Prospect Avenue in the 19090 ZIP, we found a 1965 original clay flue, cracked and spalled from decades of condensation, feeding a 40,000-BTU gas water heater. We installed a 6-inch DuraFlex stainless steel liner and sealed the oversized flue with a custom copper cap, solving the perpetual chimney dampness and preventing further mortar acid attack. Photos you can see, a plain-English verdict.
Crown Coating
Not every cracked crown needs full replacement. If the structural concrete is sound but the surface is weathered, a professional crown coating extends life by 10-15 years at a fraction of the cost. We use HeatShield and Gelco formulations designed for masonry crowns, not the hardware-store brush-on products that peel in two seasons. In Willow Grove, where older chimneys lack modern waterproofing, this is often the most cost-effective path. We clean, patch minor cracks, and apply two coats with proper cure time. The number on the estimate is the number on the invoice.
Cap Installation & Replacement
New cap installation on a sound chimney runs straightforward. Cap replacement on a neglected flue often reveals deeper issues - rusted flue edges, eroded mortar, or tile fragments blocking the draft. We inspect with a camera before we quote, so you’re not surprised by additional needs mid-job. For Willow Grove’s multi-flue chimneys, common on the larger colonials near Terwood Road, we install multi-flue caps with proper height and screening to meet current clearances.

Common Chimney Cap & Crown Problems We See in Willow Grove Homes
- Freeze-thaw cycles crack and heave uncoated masonry crowns. Willow Grove’s inland location means colder overnight lows than riverfront Philadelphia, and older chimneys built without modern waterproofing absorb water all fall. By March, the crown is spalling and the mortar joints are opening.
- Sulfuric acid condensation from oversized flues eats mortar joints invisible from the roof. Technicians working 19090 regularly find chimneys with 6-inch or 8-inch clay tile flues feeding a modern 40,000-BTU gas water heater - a holdover from the original oil-burner install. The cool, slow-moving exhaust never fully exits before condensing on the tile walls.
- Aging clay flue tiles spall and fragment, blocking flues. Fifty to seventy years of thermal cycling on tiles never designed for gas exhaust takes its toll. We find tile shards wedged beneath caps, causing dangerous backdrafting into living spaces.
- Rusted or missing caps allow water and wildlife directly into the flue. Original galvanized caps from the 1960s and 1970s have long since corroded through. A missing cap in Willow Grove means rain, squirrels, and starlings enter a flue already compromised by age.

FAQs - Chimney Cap & Crown in Willow Grove
Willow Grove’s inland location exposes masonry to more aggressive freeze-thaw cycles than riverfront Philadelphia neighborhoods, where the Delaware River moderates overnight lows. Older chimneys in 19090 were also built without modern waterproofing or crown overhangs, so water infiltration and winter heaving are more severe. If your crown has visible cracks or pooling water, call (866) 580-4069 for a free inspection - we’ll show you photos and give you a plain-English verdict.
The most common issue is a rusted-through original galvanized cap combined with an oversized flue opening. Cape Cods in the 19090 ZIP typically have 8×8 clay tile flues built for coal or oil heat; when converted to gas, the flue is too large for the exhaust volume, causing condensation that accelerates both cap corrosion and tile spalling. We replace the rusted cap with a properly sized model and inspect the flue with a camera to assess liner condition. Call for a free estimate - estimates are free, and most jobs finish in one visit.
Yes. An oversized flue requires a cap that seals tightly to the correct liner diameter, not the original tile opening, or condensation will continue to damage the chimney. We often install a stainless steel liner from DuraFlex to resize the flue, then cap that liner precisely rather than capping the oversized original flue. The custom cap prevents rain entry while maintaining proper draft. Call (866) 580-4069 to discuss whether your flue needs resizing - the inspection is free.
If the crown has surface cracks but the concrete is solid and sloped properly, a professional coating is sufficient. If the crown is flat or concave (water pools), if chunks are missing, or if the concrete crumbles when probed, replacement is necessary. We determine this with a hands-on inspection and photo documentation - you’ll see what we see. For coating, expect $280-$550; for replacement, $850-$1,800. Call for an exact quote - estimates are free.
A custom cap alone cannot fix poor draft caused by an oversized flue, but it is the essential final step after correcting the flue size. The real solution is installing a properly sized liner so exhaust gases move fast enough to exit before condensing; the custom cap then seals and protects that corrected system. We’ve done this exact repair on Prospect Avenue and throughout Willow Grove’s 1950s-1970s neighborhoods. Call (866) 580-4069 - we’ll inspect with a camera and explain what your chimney actually needs.
