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.

Ductwork Repair in Bellevue
Ductwork Repair in Bellevue means finding and fixing the leaks, separations, and corrosion that keep conditioned air from reaching the rooms you actually heat and cool. In our experience, Bellevue’s older east-side ranch homes present a specific problem: original 1960s and 1970s fiberglass flex-duct branches that have separated at the plenum takeoff, silently venting air into crawlspaces for years. A typical ductwork repair in Bellevue runs $280 – $650 depending on accessibility and how much sealing is needed. Camera inspection costs $150 – $250 when done as a standalone diagnostic.
Camera Inspection and Leak Sealing
We run a high-resolution camera from the air handler through the main trunk and branch lines. What we find in Bellevue homes is often invisible from the outside: disconnected flex-duct, crushed sections, or joints that were never sealed properly at installation. After we locate the problem, we seal it with mastic and mechanical fasteners, not tape.
Air Handler Connection Repair
Homes near Mercer Slough wetlands and the Lake Washington shoreline often route ducts through unconditioned crawlspaces. That’s where we find corroded plenum connections and mold starting on fiberglass insulation. We repair the connection, replace damaged duct sections, and seal the system so crawlspace air stops getting pulled into the return side.
Duct Replacement in Bellevue
Duct Replacement in Bellevue is the job we recommend when repair would cost more than replacing the run, or when the existing duct is too contaminated to clean safely. For a Bellevue ranch home with separated fiberglass flex-duct throughout, full replacement of branch runs typically lands between $1,800 and $4,200. A single trunk-line section replacement runs $600 – $1,400. We give you the written price before any cutting or removal starts.
Full Branch Replacement for Older Ranches
If you own a home in Lake Hills or Crossroads built in the 1960s or 1970s, there’s a strong chance your flex-duct branches are original. We replace them with insulated, code-compliant flex duct, properly sealed at every plenum takeoff. The difference in room-by-room airflow is immediate, and you stop paying to condition your crawlspace.
Post-Construction Duct Replacement
Downtown Bellevue’s ongoing high-rise and mixed-use construction leaves behind a specific problem: drywall dust and debris inside brand-new duct systems. When a developer’s final cleaning skipped the ducts, we replace or deep-clean the contaminated sections before first occupancy. Shared vertical stacks complicate this, so we coordinate with building management and neighboring units when necessary.
Trusted Brands We Service in Bellevue
We stock parts and filters for the brands Bellevue homeowners actually have, including Aprilaire, Guardsman, and Rotobrush systems. Our shop carries common plenum fittings, mastic sealant, and flex-duct sizes used in Eastside construction, which means we can often finish a repair in one visit instead of ordering parts and coming back. If your system uses Honeywell or Abatement Technologies air-quality components, our techs know how to integrate them correctly with repaired ductwork.
Common Air Duct Repair Problems We See in Bellevue Homes
- Separated flex-duct at plenum takeoffs. In 1960s – 70s homes across Lake Hills and Crossroads, original fiberglass branches pull loose from the main trunk and vent into crawlspaces. Camera inspection shows the disconnection clearly, and sealing it restores airflow fast.
- Post-construction dust in downtown high-rises. Bellevue’s construction boom means brand-new units often have drywall dust packed into ducts before anyone lives there. Shared vertical stacks let one unit’s dust migrate into neighboring returns.
- Mold-colonized ducts near wetlands. Homes near Mercer Slough and Lake Washington shoreline run air handlers through damp crawlspaces. Persistent marine humidity encourages mold on duct insulation, which then traps wildfire particulate each August.
- Crawlspace air handler corrosion. Unconditioned spaces near water push moisture through plenum connections year-round. We replace corroded collars and seal the return so damp air stops bying pulled into the home.

FAQs About Air Duct Repair in Bellevue
Bellevue condos and apartments use shared vertical duct stacks and common returns, so one unit’s disconnected branch or construction dust migrates into neighboring units. A repair that ignores the shared stack just pushes the problem next door. We coordinate with building management, inspect common returns, and often clean the shared sections before sealing your unit’s branch lines.
Eastern Washington wildfire smoke funnels through Snoqualmie Pass into the Bellevue basin each August and September, loading ductwork with fine PM2.5 particulate. If you need a repair during or after smoke season, we recommend cleaning the ducts at the same time. Repairing a leak without removing the particulate just circulates contaminated air through the sealed system. Call (980) 447-2498 and we’ll quote both together.
Rooms that never reach the thermostat setpoint, registers that barely move air, or a crawlspace that stays warm in winter are classic signs. We got a call from a condo owner in a Lake Hills building off 156th Ave SE who said her second-floor registers barely moved air while her neighbor’s unit stayed comfortable. Camera inspection found the original 1970s flex-duct branch had fully separated at the plenum takeoff, dumping air into the crawlspace. We reconnected and sealed it, then used negative pressure and HEPA filtration to clear the loose fiberglass and dust from the system.
Yes. Shared dryer vent stacks require roof or exterior wall access, and the repair often involves clearing the entire stack, not just your unit’s connection. We coordinate with building management, inspect the stack from both ends, and seal the connections to prevent exhaust from leaking into wall cavities. Written pricing applies to the whole building, and every repair includes the free-second-visit guarantee.
Yes. Our technicians follow NADCA (National Air Duct Cleaners Association) standards for inspection, repair, and cleaning on every Bellevue job. We document the before-and-after condition with camera footage, and we give you the written guarantee on all repair work. Call (980) 447-2498 to schedule a camera inspection and written estimate.
