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.

Our Chimney Cap & Crown Services in Franconia
Cap Installation
New cap installation in Franconia ranges from $220-$450 for a standard single-flue stainless unit, and $480-$920 for a custom multi-flue cap on a historic stone chimney. We size caps to your flue count and exterior dimensions, not guess. For the pre-1850 farmhouses along Allentown Road and the corridors near the Perkiomen Creek drainage, we often recommend extended overhangs and wind-resistant anchoring. Storms here lift poorly secured caps. A cap installed correctly the first time stays put.
Cap Replacement
When a cap is rusted through, wind-damaged, or was never the right size to begin with, replacement is straightforward. We remove the old unit, inspect the crown beneath it for hidden cracks, and install a new cap with proper clearances. In Franconia’s newer subdivisions, we see builder-grade caps that lasted five or six years before the mesh corroded. We replace those with 304 or 316 stainless from Gelco or DuraFlex. Done right, the new cap outlasts the roof.
Crown Repair
Crown repair addresses the concrete or mortar wash that seals the top of your chimney between the flue tiles and the edge. On Franconia’s historic fieldstone chimneys, the crown takes the worst of 40-60 freeze-thaw cycles each winter. Water gets in, freezes, and spalls the surface. We cut back deteriorated material, form a proper slope for runoff, and pour a new crown with expansion joints around each flue. For stone chimneys with lime-mortar construction, we match materials that breathe with the original masonry. Portland cement traps moisture and makes things worse.
Crown Coating
Crown coating is a flexible, waterproof membrane applied over sound but weathered crown surfaces. In Franconia, we recommend this as preventive maintenance on any crown showing early map-cracking but still structurally intact. The coating runs $340-$580 and buys years of protection against the freeze-thaw spalling that destroys unprotected crowns here. It’s particularly valuable on chimneys near the Perkiomen Creek drainage, where spring dampness lingers and efflorescence accelerates deterioration. We apply it after cleaning and minor crack filling, not as a cover-up for crumbling concrete.
Multi-Flue Cap
Multi-flue caps cover two or more flues with a single hood, common on the large exterior chimneys of Franconia’s Pennsylvania German farmhouses. These chimneys often served cooking hearths and heating stoves simultaneously, and the flue spacing can be irregular. We measure on-site and fabricate or order caps with proper height clearances and mesh screening. A multi-flue cap installed after crown repair protects the entire assembly from wind-driven rain and animal entry. Prices start around $520 and run to $1,100 for custom copper or oversized stainless units.
Custom Cap
When standard sizes don’t fit your chimney’s dimensions, pitch, or architectural requirements, we build custom. This includes oversized rectangular caps for historic stone stacks, steep-pitch models for high-wind exposure, and decorative copper caps that match period details. Custom caps in Franconia typically fall between $680-$1,400 depending on metal choice and complexity. We template on-site, fabricate to order, and return to install with proper flashing integration.

Common Chimney Cap & Crown Problems We See in Franconia Homes
- Storm-driven wind displaces caps on tall fieldstone chimneys. The multi-flue caps on historic farmhouses along Harleysville Pike and Allentown Road sit high above the roofline and catch full wind exposure. When anchoring fails or the crown beneath crumbles, the cap lifts or shifts, exposing flue liners to direct rain and snowmelt that accelerates spalling at the crown.
- Freeze-thaw cycles crack crowns within one or two seasons. Franconia’s 40-60 annual freeze-thaw events relentlessly attack the soft, hand-cut limestone and sandstone mortar in pre-1850 chimneys. A crown that looks sound in October can be spider-webbed by March, allowing water to run behind flashing and stain ceilings in the room below.
- Oversized fieldstone flues with modern liners rattle loose and pack with debris. Previous owners often dropped a wood-stove liner into a flue built for an open cooking hearth. The liner sits with an air gap inside the stone shaft, and that gap fills with decades of loose mortar, leaves, and bird nesting. The cap looks fine from the ground. The hazard is invisible until a camera goes up.
- Prefabricated chase enclosures in newer subdivisions suffer crown wash failure. The poured concrete crown wash on vinyl-sided chases cracks and separates from the flue collar, letting water run directly into the chase cavity. We’ve found rotted framing and rusted fireboxes in homes off Route 113 where this went unaddressed for two seasons.

Costs run higher on historic stone chimneys because we match lime-mortar mixes and sometimes need custom forming for irregular flue spacing. Access difficulty matters too. A three-story fieldstone stack with a steep roof pitch takes longer than a single-story chase. We assess on-site, show you photos, and give you a written estimate before any work begins. Call (610) 991-8179 for an exact quote.

FAQs - Chimney Cap & Crown in Franconia
The crack is on top where you can’t see it, and wind-driven rain is entering behind the flashing. On Franconia’s historic stone chimneys, freeze-thaw spalling opens hairline fractures in the crown that direct water into the gap between masonry and flashing. That water runs down the interior and stains your ceiling. We find this exact pattern on farmhouses near the Perkiomen Creek drainage, where damp masonry stays wet longer. A Level-2 camera inspection and crown assessment confirms it. Call (610) 991-8179 for a free inspection.
Inspect annually before burning season, and plan replacement every 12-18 years for stainless, 20-25 for copper, sooner if wind events damage anchoring. The multi-flue caps on Franconia’s tall fieldstone stacks endure more wind shear than caps on lower suburban chimneys. After any severe storm, check from the ground for tilting, gaps, or missing mesh. We include cap and crown condition in every Level-2 inspection, with photos you can see.
Yes, if other flues remain active or could be used later, but the cap must be sized to the liner’s termination height and clearance requirements. The bigger issue we find in Franconia: the gap between the liner and the oversized fieldstone shaft. A multi-flue cap with proper mesh keeps animals and debris out, but it won’t fix draft failure or hidden fire risk from packed nesting material. We camera-inspect the full shaft before recommending any cap. The right cap on the wrong flue condition is a bandage, not a repair.
Crown coating is more necessary here than in many markets because of the freeze-thaw severity. Patching individual cracks with standard mortar buys a season or two. The flexible membrane in a professional crown coating system from HeatShield or similar expands and contracts with temperature swings, preventing the rapid recurrence of cracking that we see on unprotected crowns after Franconia winters. For historic chimneys with sound but weathered crowns, coating is preventive maintenance that avoids a full rebuild. For crumbling concrete, we rebuild first, then coat.
Check three things from the ground: cap position and mesh integrity, visible crown cracks or spalling, and any new interior stains on the ceiling near the chimney. If you have a historic stone chimney, also note whether mortar joints on the upper courses look powdery or recessed. In Franconia, the combination of freeze-thaw cycling and Perkiomen Creek dampness means crown and cap damage progresses faster than homeowners expect. Don’t climb the roof. Our Level-2 inspection covers cap, crown, flue condition, and liner fit with photos and a written report. Call (610) 991-8179 to schedule before the weather turns.
