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 Duct Repair & Sealing Across Burke
Duct repair and sealing in Burke, VA typically costs between $280 and $850 depending on whether the job involves spot mastic sealing or full flex-duct replacement, and most Burke Centre homes need structural ductwork attention rather than simple cleaning. Our crews are scheduled from our Washington, DC office and carry Rotobrush inspection cameras, Guardsman mastic compounds, and Honeywell airflow meters on every Burke truck. Call (240) 771-1508 for a written estimate before any panel comes off.
We know Burke’s streets because we’ve been working them since 2013. The Burke Centre planned community - those winding loops off Burke Centre Parkway, the townhome clusters near Wards Grove Circle, the split-foyers along Burke Lake Road - these aren’t just addresses to us. They’re homes running ductwork that was installed when Reagan was president. That matters when you’re deciding whether a register blowing warm air in July means a dirty duct or a collapsed one.
Why CleanRun Air Duct Cleaning Ashburn Is Burke’s Preferred Duct Repair & Sealing Company
Burke homeowners don’t buy from brochures. They buy from documentation. That’s why every Duct Repair & Sealing job we run in Fairfax County starts with a written price under Haven Standard Clause 1 and ends with a photo record of every duct run, before and after, delivered to your inbox before the truck leaves your driveway.
Our reputation in Burke is built on what we can show, not what we claim. We’ve served more than 52,000 homes since 2013, every one with that same written price and documented photo record. When a Burke Centre owner on Oak Leather Court calls us back because a neighbor asked who fixed their second-floor airflow, we know the work spoke for itself.
Scheduling runs from our Washington, DC office, so Burke appointments typically book within 48 to 72 hours. Technicians are background-checked, uniformed, and identified by name before arrival - Haven Standard Clause 3: Verified Crews. You’ll know who’s walking up your steps and what equipment they’re carrying.
The local knowledge matters. A technician who doesn’t know that Burke’s 1980s split-foyers often have duct-board plenums in the garage ceiling, or that Burke Centre townhomes share chase walls where flex-duct separates at fittings, will vacuum your registers and miss the actual problem. We train for Burke’s housing stock specifically.
Our Duct Repair & Sealing Services in Burke
Flex Duct Repair
Burke Centre’s late-1970s and 1980s townhomes were built with builder-grade flex duct that used thinner inner liners than modern code requires. After forty years of Northern Virginia humidity cycling - that May-through-September stretch where your air handler runs fourteen hours a day - those liners sag, tear, or pull completely free of the collar fittings. We got a call from a Burke Centre townhome on Wards Grove Circle where the second-floor registers were blowing weak, musty air; our tech ran a camera inspection and found the original flex-duct inner liner had separated from the fitting above the air handler, dumping conditioned air into the joist bay. We reconnected and mastic-sealed the run, then performed source removal with negative pressure and HEPA filtration on the supply and return ducts, and the static pressure at the registers came back to normal. Flex duct repair in Burke runs $340-$620 depending on linear footage and accessibility.
Mastic Sealant Application
Sheet-metal duct systems in Burke’s colonial-style homes - the ones built during the 1980s boom off Burke Lake Road and around the Kings Park area - were sealed at the joints with tape that degrades. Not duct tape, despite the name; fiberglass mesh tape with adhesive that turns brittle after two decades. We apply Guardsman mastic sealant, a water-based compound that remains flexible, to every accessible joint in the plenum and trunk lines. The camera shows the gaps before we start. The photo record shows them sealed after. Mastic sealing for a typical Burke single-family system runs $280-$450.
Air Leak Repair
Air leaks in Burke homes don’t announce themselves. They show up as rooms that won’t cool below 78°F in August, or as utility bills that climb every summer despite a new compressor. We pressure-test the duct system with an Abatement Technologies duct blaster, identify leakage points with theatrical smoke, then repair with mastic, mechanical fasteners, or replacement flex as the findings dictate. Burke’s older duct-board systems are especially prone to leakage at the plenum corners where the board meets the air handler cabinet. Air leak diagnosis and repair in Burke typically runs $380-$720.
Metal Duct Repair
The galvanized steel trunk lines in Burke’s pre-1992 homes corrode at the low points where condensation pools. Northern Virginia’s humidity cycle - outdoor dew points in the 70s from June through August - means supply ducts running through unconditioned attic spaces sweat continuously. We cut out corroded sections, fabricate replacements, and seal with mastic and mechanical draw bands. Metal duct repair in Burke runs $420-$850 depending on material gauge and access.
Duct Insulation
Condensation on poorly insulated supply runs during heat-index days above 100°F feeds mold growth on old duct-board. We wrap accessible metal ducts with formaldehyde-free insulation and vapor barrier, or replace deteriorated duct-board with insulated flex or sheet metal as appropriate. Duct insulation in Burke typically runs $320-$580.

BeforeAfterTrusted Brands We Service in Burke
Our Burke trucks stock Honeywell zone dampers and Aprilaire media cabinets for same-day replacement when inspection finds failed components. We don’t order parts from a warehouse across the state and make you wait. The Abatement Technologies HEPA negative-air machines we use for source removal are the same units specified in hospital IAQ protocols - you can look up the model numbers yourself. Every brand we name is one you can verify independently, because Haven Standard Clause 1 doesn’t just cover pricing. It covers transparency about what equipment enters your home.
Common Duct Repair & Sealing Problems We See in Burke Homes
- Collapsed flex-duct liners in Burke Centre townhomes. The original inner liners from the 1980s build-out separate from collar fittings after decades of humidity expansion and contraction. Conditioned air dumps into joist bays or chase walls. The homeowner feels weak airflow and assumes the compressor is failing.
- Duct-board delamination in split-foyers near Burke Lake Road. The fiberglass matting separates from the foil facing when condensation soaks the board repeatedly. Fibers shed into the airstream. The camera shows a fuzzy, degraded interior surface that vacuuming alone won’t fix.
- Pollen-driven filter failure overwhelming return systems. Fairfax County’s oak, pine, and maple spring pollen load is severe. When Burke homeowners delay filter changes, particulate bypasses the filter and packs into the return plenum, masking seal failures and stressing the blower motor bearings.
- Corroded metal trunk lines in attic installations. The galvanized steel used in 1980s Burke builds was often 30-gauge, thinner than modern 26-gauge code. Condensation at low points rusts through from the inside out. The first sign is a water stain on the ceiling below, not a duct noise.

What moves a Burke job toward the higher end: multiple flex-duct runs requiring attic access, duct-board plenum replacement, or corrosion repair in finished ceiling spaces. What keeps it lower: single-run flex repair with basement access, or straightforward mastic sealing of accessible metal joints.

FAQs - Duct Repair & Sealing in Burke
Run your system on a hot afternoon and check whether upstairs registers blow noticeably weaker than downstairs, or whether any room stays more than 4°F warmer than the thermostat setting. Those symptoms usually mean collapsed flex-duct liner or separated fittings, not debris. A camera inspection confirms it in ten minutes. Call (240) 771-1508 and we’ll show you the footage before discussing repair options.
New construction in Burke’s infill areas - the lots being developed off Old Keene Mill Road extensions - generates drywall dust, sawdust, and fiberglass insulation fragments that settle in ducts during the months between rough-in and final walkthrough. Builders rarely clean before certificate of occupancy. If you bought new, schedule an inspection. The camera will show whether the ducts are clean enough to pass, or whether source removal is warranted before you move furniture in.
Sealing fixes the pressure loss that makes your system run longer to achieve the same temperature, which in turn reduces the condensation load on cold supply surfaces. In Burke’s climate, an unsealed duct system in a vented attic can lose 20-30% of its conditioned air to the attic space. That wasted air is air that should be dehumidifying your living space. Mastic sealing restores design airflow and reduces the humidity strain that degrades old duct-board.
Every three to five years for camera inspection, sooner if you notice airflow changes or utility bill spikes. Burke’s original builder-grade systems are now 35-47 years old. The fiberglass duct-board and early flex-duct materials weren’t designed for that lifespan. Inspection finds delamination, liner separation, or corrosion before they become ceiling leaks or blower motor failures.
We use Rotobrush mechanical agitation with Abatement Technologies negative-pressure HEPA extraction on every source-removal job. Vacuuming registers without containment and filtration releases particulate into your living space. The photo record shows the difference: our after photos display clean duct interior, not just clean register grilles. Haven Standard Clause 2 requires documented method, not just documented result.
