The brick colonials and split-levels off Gallows Road, the ranchers near the Dunn Loring-Merrifield Metro station, the double-flue stacks in the neighborhoods around Idylwood Road - we’ve seen what Northern Virginia’s freeze-thaw winters do to them, and we know what Fairfax County inspectors want to see before they’ll sign off on a sale. Our dispatch is coordinated from our Washington, DC office, but our trucks are in Dunn Loring regularly, and we carry the liners, crowns, and refractory materials to handle most jobs without ordering parts.

Our Chimney Liner & Rebuild Services in Dunn Loring

Stainless Steel Liner Installation

Dunn Loring’s mid-century brick colonials and split-levels were built with terra cotta flue liners that crack predictably at 50 to 70 years old. A stainless steel liner - we install insulated DuraFlex and Gelco systems - creates a new, properly sized flue inside the existing chimney, containing flue gases and protecting the surrounding masonry. For homes near the Dunn Loring-Merrifield Metro with oil-to-gas conversions, this is often the only way to bring an oversized original flue into compliance with current Fairfax County codes. Most installations run $2,200-$3,800 for a single flue, depending on height and whether the smoke chamber needs parging.

Flexible Liner Systems

Not every Dunn Loring chimney is straight. The offset flues in some 1960s split-levels off Gallows Road require a flexible liner that can navigate bends without losing draft performance. We use professional-grade flexible stainless systems from DuraFlex, sized precisely for the appliance they’re serving - fireplace, furnace, or water heater. A flexible liner installation in Dunn Loring typically costs $2,600-$4,200, with the higher end covering double-bend offsets and insulation wraps for exterior chimneys.

Liner Replacement

When a terra cotta liner has cracked through its full height or suffered spalling damage that exposes the chimney wall to flue gases, partial repairs aren’t enough. We remove the damaged sections - or the entire original liner if necessary - and install a new system engineered for your current appliances. In Dunn Loring, this work often reveals deferred crown damage and deteriorated mortar joints that need attention before the new liner goes in. A full liner replacement with associated crown and mortar repair runs $3,500-$6,000.

Partial Rebuild

Sometimes the liner is sound but the structure around it isn’t. Spalled brick faces, deteriorated crown shoulders, and failed flashing let water into the chimney stack, accelerating freeze-thaw damage through Northern Virginia’s volatile winters. Our partial rebuilds address the damaged courses and crown while preserving sound masonry below. On a typical Dunn Loring colonial with crown and upper-course damage, expect $2,800-$5,500.

Full Chimney Rebuild

For chimneys where the damage extends below the roofline - extensive mortar failure, leaning stacks, or multiple cracked flues with compromised surrounding brick - we dismantle and rebuild from a stable point upward. This is serious work, and we don’t recommend it unless we’ve documented the damage with camera inspection and shown you the photos. A full rebuild in Dunn Loring, including new flue liners, runs $6,500-$12,000 depending on height, brick matching, and whether we’re working with one flue or two.

When a Fairfax County inspector’s notice arrives with a closing deadline attached, that turnaround matters.

Common Chimney Liner & Rebuild Problems We See in Dunn Loring Homes

• Original terra cotta liners cracking at 50-70 years old. Dunn Loring’s housing stock was built in a concentrated wave from 1950 to 1975, which means thousands of chimneys hit this failure window simultaneously. Northern Virginia’s repeated freeze-thaw cycling accelerates the damage - water infiltrates hairline cracks, expands when it freezes, and widens them through dozens of thermal cycles each winter.
• Gas appliances vented into oversized oil-furnace flues. When Dunn Loring homes converted from oil to gas, many chimneys were never properly relined. The resulting weak draft produces condensation inside the flue, accelerating liner deterioration and producing the deficiency notices Fairfax County inspectors routinely flag during real estate transactions near the Metro station.
• Deferred crown and flashing repairs letting water into aging mortar joints. What looks like cosmetic spalling on brick faces often signals deeper moisture intrusion. Once water reaches the liner interface, freeze-thaw damage compounds quickly - and the repair that could have been a crown rebuild becomes a liner replacement or partial rebuild.
• Double-flue chimneys with improper separation between fireplace and utility flues. Many Dunn Loring colonials have this configuration, and it’s frequently oversized for modern gas equipment. Without proper liner separation and sizing, flue gases can migrate between channels or fail to achieve adequate draft, creating both safety and code-compliance issues.
