Our Chimney Repair Services in Calverton
Mortar Repointing
The mortar joints in Calverton’s 1960s and 1970s masonry were never meant to survive six decades of mid-Atlantic freeze-thaw. When we grind out failed joints on chimneys near Cherry Hill Road or along the Calverton Boulevard corridor, we match the original joint profile and pack with professional-grade mortar formulated for this climate. Done right, repointing adds twenty years of service. Typical repointing on a Calverton chimney runs $850-$1,400 for a standard two-flue stack.
Spalling Brick Repair
Spalling - that flaking, popping, and crumbling of brick faces - is epidemic in Calverton because summer humidity drives moisture deep into porous older brick, then winter freeze-thaw blows the surface off. We see it worst on south- and west-facing chimney exposures where daily temperature swings are most extreme. Our technicians remove damaged brick, source matching replacements, and rebuild with the same care as original construction. Single-area spalling repair in Calverton typically costs $400-$750; extensive face rebuilds range $1,200-$1,800.
Chimney Waterproofing
Calverton’s combination of heavy clay soils, mature tree canopy, and humid summers creates constant upward and lateral moisture pressure on chimney bases. Our waterproofing treatment uses breathable silane-siloxane sealers from professional-grade suppliers, never the hardware-store coatings that trap moisture inside. We apply after any needed repointing, with special attention to the chimney-shoulder junction where roof runoff pools. Waterproofing a typical Calverton chimney runs $350-$550 and carries our Done Right Promise.
Flashing Repair
Step flashing and counterflashing around chimney penetrations fail predictably in Calverton’s housing stock: original galvanized steel rusts through, caulking dries and splits, and the gentle roof pitches common here let water linger. We fabricate custom flashing from long-wearing materials and seal with proper integration into existing roofing, not surface goop that peels in two seasons. Flashing repair in Calverton typically runs $250-$600 depending on access and roof complexity.

Common Chimney Repair Problems We See in Calverton Homes
- Crown deterioration on mid-century construction. The original mortar crowns in Calverton’s 1960s-70s homes were poured thin and reinforced poorly. After fifty winters, they’re cracked powder that funnels water straight into the chimney core.
- Gas insert backdrafting from oversized flues. Homeowners near Calverton Center and along Old Columbia Pike call us convinced their insert is defective. More often, the original 12×12 clay flue was never lined down to 6 inches, so exhaust cools, condenses, and spills into the room.
- Efflorescence and mortar joint erosion. Calverton’s humid summers and hard freezes create the perfect cycle for white mineral bloom and crumbling joints, especially on chimneys shaded by the mature oaks that now tower over these original lots.
- Flashing failure at low-slope roof intersections. The split-levels and ranches common here have gentle pitches where ice dams and leaf accumulation accelerate rust at the chimney base.
