Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterFast, Reliable Air Duct Repair Across Alexandria
Air duct repair in Alexandria usually means finding and sealing the leaks, crushed runs, and bad transitions that a routine cleaning exposes but doesn’t fix. In this city’s older housing stock, that often costs between $350 and $1,200 depending on how much of the original ductwork is still in place and how accessible it is. If you’re hearing a rattle in the walls of a Del Ray bungalow or smelling musty air from the registers of an Old Town rowhouse, call us at (980) 447-2498. We’re Linden Air Duct Cleaning, and we’ve been repairing ductwork in Alexandria long enough to know what’s behind those plaster walls before we open them up.
Why Linden Air Duct Cleaning Is Alexandria’s Preferred Air Duct Repair Company
Alexandria homeowners call us because we tell them exactly who is walking through the door before the van ever arrives. Every technician carries a photo ID badge, arrives in a clean marked uniform, and their name and photo are sent to you ahead of the appointment. That’s the Threshold Standard we’ve operated under since 2004, and it matters in a city where letting a stranger into an 1880s rowhouse on a narrow Old Town street is a real decision. Marcus Veale leads our repair crews, and he’s the one who makes sure the written price lands in your hand before any work begins.
Our Alexandria customers consistently mention two things in reviews: the technician showed up when promised, and the final invoice matched the written quote. No bait pricing, no surprise line items added while the van is parked on King Street. The job gets a written guarantee, and if a covered repair fails, we come back at no charge. That’s not a marketing line. It’s in writing, on every repair ticket.
Air Duct Replacement in Alexandria
Air Duct Replacement in Alexandria is frequently the right call when the original galvanized steel from a 1940s Cape Cod has rusted through at the seams or when a flex run in an Old Town wall cavity has been crushed beyond repair. The job involves removing the failed sections, sizing the replacement to the existing air handler, sealing every joint, and testing the system under pressure. A typical full-trunk replacement in an Alexandria rowhouse runs $1,800 to $4,200. Partial replacements, like replacing a single crushed supply run serving one or two rooms, typically run $400 to $900.
Material Choices for Older Homes
Most Alexandria replacements use rigid galvanized steel or sealed flex with a reinforced liner. For homes with original plaster-and-lath chases, we match the duct dimensions to the existing cavity rather than forcing a square peg into a round hole. For tight floor-joist bays in Del Ray and Rosemont, sealed rigid duct holds shape better than flex and won’t sag into the bay over time.
When Replacement Beats Repair
Replacement is the smarter investment when a duct run has multiple pinhole leaks, when the interior liner is delaminating, or when a previous homeowner’s DIY patch has made the section structurally unreliable. In Alexandria’s humid summers, a leaking duct also pulls attic air into the system, so replacement and proper sealing is often what actually fixes a dusty-house complaint. We’ll show you the camera footage before we recommend pulling anything out.
Ductwork Repair in Alexandria
Ductwork Repair in Alexandria covers the jobs that don’t require full replacement: re-sealing plenum joints, replacing crushed flex sections, adding support hangers in sagging runs, rebuilding bad transitions, and reconnecting ducts that have separated at the boot. The cost for a targeted repair on one or two problem areas in an Alexandria home typically runs $350 to $700. Larger repairs, like re-sealing an entire trunk line or replacing several crushed runs, run $800 to $1,500.
Sealing the Joints That Quietly Leak
Most repair jobs in Alexandria’s pre-war homes come down to sealing. Mastic and UL-listed foil tape on every joint, collar, and plenum penetration on the section we’ve opened. An unsealed return pulling attic dust through a plaster-and-lath cavity is the most common single fault we find, and it’s the one a cleaning alone can’t touch.
Rebuilding Transitions After Old Conversions
When a radiator-era home was converted to forced air decades ago, the transition pieces were often improvised. We rebuild those with proper collar sizes, sealed seams, and the right slope so condensation drains rather than pools. It’s unglamorous work, but it’s the difference between a system that works and one that fights itself every cycle.
Trusted Brands We Service in Alexandria
Our technicians repair and replace ductwork from every major manufacturer, and we keep common parts stocked for faster turnaround on Alexandria jobs. We run professional-grade equipment from Rotobrush and Nikro, and we work with air-quality products from brands like Honeywell and Guardsman when a repair calls for filtration or surface treatment. We also offer Dryer Vent Cleaning - Alexandria as part of our full-service approach. If your system has an Aprilaire filter housing that’s leaking at the cabinet, we’ll fix that too. You don’t need to call three companies; one repair visit covers the ductwork and the components attached to it.
Common Air Duct Repair Problems We See in Alexandria Homes
- Crushed flex runs in Old Town wall cavities. Tight chases behind original plaster and lath bend flex at sharp angles, and over decades the liner collapses. Debris piles up at the pinch point, airflow drops, and the blower motor works harder every cycle.
- Improvised transitions from radiator-era conversions. Homes that switched from steam or oil heat to forced air often have mismatched collars and unsealed plenum joints. Those gaps leak conditioned air into joist bays and attics instead of rooms.
- Dead-end runs from old remodels. A remodel in a 1950s Rosemont Cape Cod leaves the old supply duct capped but still connected to the trunk. It collects condensation all summer and feeds microbial growth that spreads into the rest of the system.
- Rusted-through galvanized in humid basements. Alexandria’s 70%+ summer humidity and low elevation near the Potomac accelerate rust on uninsulated metal duct in crawlspaces and basements. Pinhole leaks form within decades, not generations.
Pricing for Air Duct Repair in Alexandria, VA
Whole-system duct sealing in a typical Alexandria rowhouse runs $900 to $1,800. A targeted repair on one or two crushed flex sections runs $350 to $700. Full duct replacement in an average Alexandria home runs $1,800 to $4,200. What moves the number is access: a run in an open basement is straightforward; a run behind an Old Town plaster wall with no existing chase takes time. Every job gets a written price before we start. No per-vent pricing, no bait quote, no invoice that grows while the van is parked on Mount Vernon Avenue. Call (980) 447-2498 and we’ll walk you through what your specific home is likely to need, based on the age and layout of the house.

FAQs About Air Duct Repair in Alexandria
Because Old Town’s historic district has a Board of Architectural Review that restricts structural alterations, so decades of HVAC retrofits were forced to route ducts through original 18th- and 19th-century floor joists and plaster-and-lath wall cavities rather than cutting new chases. Those tight, improvised runs hold over a century of accumulated debris, including coal and oil combustion residue from the home’s pre-forced-air era. A cleaning removes what’s loose; a repair fixes the leak or crushed section that has been trapping it for years. Call (980) 447-2498 to get a camera inspection scheduled.
Alexandria sits at low elevation in the humid Potomac River basin, and summer relative humidity regularly exceeds 70%, which means condensation inside unsealed or dead-ended duct runs is common. We prioritize sealing work and antimicrobial treatment in Alexandria more than we would in drier inland markets. A small air leak that would be insignificant in a dry climate will feed mold here within a season. That’s why our Alexandria repair quotes often include sealing and sanitizing after the mechanical fix is done.
Yes, in most cases. Del Ray bungalows from the 1920s and ’30s have tight floor-joist bays that were never designed for forced air, but we can usually pull a new sealed flex or rigid section through the existing cavity rather than opening new chases. If the cavity itself has collapsed or the joists have shifted, we’ll show you the camera footage and talk through the least invasive option. The goal is always to fix the duct without turning a repair into a renovation.
A camera inspection in an Alexandria home typically finds exactly what our Air Duct Repair team expects in this housing stock: crushed flex at sharp angles behind plaster walls, separated boots at register connections, dead-end runs left over from decades-old remodels, and rusted-through seams in humid basements. In a Del Ray bungalow off Mount Vernon Avenue, our tech found an original 1930s return dropping through a plaster-and-lath cavity with a crushed section behind the baseboard. A cleaning would never have revealed it. The camera did, and the repair stopped the homeowner’s dusty-house complaint at the source.
Yes, every Alexandria repair job follows NADCA standards for source removal, system cleaning, and mechanical repair. We use negative-pressure extraction with agitation tools from brands like Rotobrush and Nikro, and every repair is sealed with mastic and UL-listed tape to NADCA specifications. When a job involves anti-microbial treatment in Alexandria’s humidity, we use EPA-registered products appropriate for HVAC surfaces. The written guarantee covers the repair for 365 days, and if a covered repair fails, we return at no charge.
