Our Chimney Repair Services in McLean

Chimney Rebuilding

McLean’s teardown-and-rebuild cycle keeps us busy. A 1960s rancher comes down, a 6,000-square-foot custom home goes up, and sometimes the old flue gets hidden inside new walls without proper decommissioning or capping. We’ve found original clay-tile liners deteriorating inside otherwise brand-new construction, and we’ve rebuilt from the roofline up when freeze-thaw damage has compromised structural integrity. A full chimney rebuild in McLean typically runs $3,200-$4,500, with partial rebuilds starting around $1,800. We use HeatShield refractory mortar and Olympia Chimney components - professional grade, no builder-grade substitutes.

Flashing Repair

Flashing is where your chimney meets the roof, and it’s the most common leak point we see in McLean’s older colonials. The original step flashing on a 1970s or 1980s brick home has often corroded or pulled away, letting water run straight into the attic and down the flue. In attached homes along narrow lots, poor flashing on one unit can damage the neighboring structure too. Flashing repair in McLean typically costs $650-$1,400 depending on roof pitch and accessibility. We fabricate custom flashing on site and seal with professional-grade compounds - not caulk from a hardware store.

Chimney Waterproofing

Northern Virginia’s freeze-thaw cycling - temperatures crossing 32°F multiple times per week from November through March - destroys unprotected masonry. Water seeps into brick pores, freezes, expands, and spalls the face right off. McLean’s high summer humidity then keeps flue interiors damp between burning seasons, accelerating liner deterioration. We apply breathable, vapor-permeable waterproofing agents that let the chimney dry out while blocking liquid water. Waterproofing a typical McLean chimney runs $800-$1,600 and adds years of service life to sound masonry.

Mortar Repointing & Tuckpointing

The mortar joints on McLean’s exposed masonry chimneys take the worst of it. We grind out deteriorated mortar to proper depth and repoint with color-matched, weather-resistant mortar - not a surface skim that will flake off in two winters. Tuckpointing for cosmetic refinement is available where the brick is sound but the appearance matters. Repointing a standard McLean chimney runs $1,200-$2,200. We match the original mortar profile so the repair disappears.

Spalling Brick Repair

Spalled brick - the face popped off by freeze-thaw pressure - is everywhere in Langley and Chesterbrook. Once the hard outer face is gone, the soft inner brick erodes fast. We replace spalled units with matching brick and address the water source, or we rebuild the affected courses if the damage is extensive. Spot brick replacement in McLean starts around $350-$800; larger areas scale from there.

Common Chimney Repair Problems We See in McLean Homes

• Spalling brick and mortar crowns from freeze-thaw cycles. McLean’s exposed masonry chimneys, especially in Langley and Chesterbrook, suffer aggressive spalling when temperatures cross freezing repeatedly. The crown - the concrete cap atop the chimney - cracks first, then water penetrates the brick below.
• Cross-contamination in shared flues of attached properties. In McLean’s closely spaced colonials, a neighbor’s appliance venting into the same stack can push creosote odors and combustion byproducts into your home. We’ve traced “mystery smells” to exactly this - a water heater or boiler on the other side of the wall.
• Improperly capped or decommissioned flues in teardown-and-rebuilds. New construction sometimes encapsulates old flues without proper capping, creating water intrusion paths and hidden liner deterioration that doesn’t surface until stains appear on drywall.
• Animal nests and leaf debris from dense hardwood canopy. The mature oaks and maples along Georgetown Pike drop leaves straight into uncapped flues, and squirrels or raccoons nest in chimneys used only occasionally. We pull nests almost routinely in older neighborhoods.

We were called to a 1970s brick colonial off Georgetown Pike where a second-degree creosote smell was seeping into the living room. Our tech found the original clay-tile flue liner spalling and a squirrel nest blocking the chimney cap, which had also trapped leaves from the overhanging hardwoods. After pulling the nest, we installed a DuraFlex liner and Gelco crown coat, restoring proper draft and stopping the odor.
