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 Kent
Air duct repair in Kent usually means one of three things: a disconnected or torn flex run, a crushed section of rigid duct, or a leaking plenum connection. Most jobs run $320 – $680 depending on how much of the system is compromised and how accessible the damaged section is. We’ve worked Kent homes from East Hill to the valley floor long enough to know which failures show up where, and we’ll give you a written price before any work begins. Call (980) 447-2498 and we’ll send a technician who’s background-checked, identity-verified, and introduced to you by name and photo before they knock.
Why Linden Air Duct Cleaning Is Kent’s Preferred Air Duct Repair Company
Linden Air Duct Cleaning has served homeowners as part of the Threshold Group family since 2004, operating to the Threshold Verified standard on every job. That standard is not a slogan. It means the technician coming to your Kent home has been background-checked, identity-verified, and photo-badged, and we send you their name and photo before the visit so you know exactly who is at the door.
We carry professional-grade equipment from Rotobrush and Nikro into Kent homes, which matters when a repair requires negative-pressure extraction or camera inspection of hard-to-reach duct runs. The tech will show a photo ID badge at the door, no exceptions. And every repair is covered by a 365-Day Done Right Promise in writing: if the fix does not hold, our team returns at no charge. Marcus Veale oversees our work across the South King County market, holding every job to that standard.
Kent homeowners regularly tell us they called us because a competitor’s price changed after the van arrived. That does not happen with Linden. The price is written before work starts, every single time, for every repair.
Ductwork Repair in Kent
Ductwork Repair in Kent typically involves reconnecting separated flex runs, sealing leaking joints, patching punctured rigid duct, and replacing failed collars, connectors, and takeoffs. In Kent’s housing stock, the most common repair call we receive is a disconnected or torn supply run in the attic or crawlspace. Homeowners notice it when one room stops heating or cooling properly, or when the system runs longer than it should. A standard ductwork repair for a single failed run in Kent runs $320 – $520. Multiple failures or repairs in confined attic spaces run higher.
Reconnecting and Sealing
When a flex run separates from its collar, conditioned air dumps into the attic instead of the room it is supposed to serve. We reconnect the run, mechanically fasten rather than staple, and seal the connection with mastic. Then we run a pressure test to confirm the seal holds. For Kent homes with older ductboard plenums, we also check the plenum-to-duct connections, which are a common source of slow, invisible leakage.
Patching Damaged Sections
Crushed or punctured rigid duct is common in Kent crawlspaces where plumbing work or stored belongings have taken a toll on the runs. We cut out the damaged section and install a matching replacement, typically galvanized steel or aluminum. If the surrounding duct is in poor condition, we tell you straight: patching a segment that will fail again in a year is not a repair, it is a delay.
Duct Replacement in Kent
Duct Replacement in Kent is the better call when the existing runs are too deteriorated, undersized, or contaminated to justify patching. This is especially true in East Hill homes from the late 1980s and early 1990s, where original flex duct has been degrading for three decades or more. Replacing a short supply run typically costs $400 – $700. Replacing multiple runs, or a main trunk section, runs $900 – $2,200 depending on length, diameter, and access. Every quote is written before work begins.
Replacing Failed Flex Runs
Flex duct has a finite lifespan, and the material breaks down faster in Kent because of the sustained attic humidity our climate produces. When the inner liner tears, the run starts pulling insulation fibers into the airstream. Replacement means installing new insulated flex, properly sized to the room’s air requirements, connected with clamps at every collar and supported to manufacturer specifications. We do not staple.
When Repair Is Not Enough
There are times when a repair would solve the immediate leak but leave a system that is fundamentally compromised. If a camera inspection shows multiple failed runs, evidence of vermin damage, or pervasive mold colonization inside the ducts, replacement is the honest recommendation. We will show you the camera footage and explain what we are seeing before you commit to anything.
Trusted Brands We Service in Kent
We service and repair ductwork connected to every major HVAC brand found in Kent homes, and we stock common connectors, collars, takeoffs, and flex duct locally so we are not running back to a supplier mid-job. Our repair work is compatible with systems using equipment from Honeywell, Aprilaire, and Abatement Technologies, and we run professional-grade Rotobrush and Nikro tools on our own rigs. That means the brand of your furnace or air handler does not determine whether we can repair your ducts properly. It is the condition of the ductwork itself that matters.
Common Air Duct Repair Problems We See in Kent Homes
- Stapled flex-duct collars in East Hill tract homes. The late-1980s buildout along the East Hill produced thousands of homes where original flex runs were stapled at the collar instead of clamped. Over time, those staples tear through the flex liner, and attic particulates and insulation fibers get drawn directly into the supply airstream. The fix is mechanical reconnection and clamping, not another staple job.
- Separated takeoffs in valley-floor crawlspaces. Kent’s Green River Valley floor holds moisture, and crawlspace humidity accelerates the degradation of duct tape and old mastic at takeoff connections. Runs slowly separate from the trunk, leaking conditioned air into the crawlspace for years before the homeowner realizes the system is underperforming.
- Sagging trunk lines in downtown Kent homes. Homes in the downtown core were often retrofitted for forced air decades after construction, and the duct runs were squeezed into spaces never designed for them. Sagging trunks hold moisture, trap debris, and eventually fail at the hanging supports. We see this frequently in 1950s and 1960s housing stock.
- Late-summer wildfire residue buildup. Kent’s return-air intakes pull in fine particulate from eastern Washington wildfire smoke that settles into duct runs and does not get captured by standard filters. When we open those systems, the buildup is visible. A repair that ignores the contamination leaves the system clean only on paper.
Pricing for Air Duct Repair in Kent, WA
Air duct repair in Kent runs $320 – $680 for a typical single-failure repair, with more extensive work like multiple-run replacement ranging from $900 – $2,200. What moves the price in Kent specifically is access: East Hill split-level attics with tight clearances take longer than a valley-floor ranch with a full-height crawlspace. Downtown Kent homes with retrofitted duct runs can require more camera work to locate the failure before repair begins. You will receive a written price before any work starts, and every repair is covered in writing with a free second visit if the repair fails. Call (980) 447-2498 for an exact quote, free of charge.

FAQs About Air Duct Repair in Kent
If your home was built during the late-1980s East Hill tract surge and the ducts have never been opened, it is a real possibility. That decade’s rapid buildout produced widespread stapling rather than clamping at flex-duct collars, and we find it in Kent more than in Renton or Auburn, which were built on different timelines. The telltale signs are fiberglass dust on registers, unusual filter loading, and rooms that never reach the set temperature. Call (980) 447-2498 and we will run a camera inspection to confirm what is happening before recommending any repair.
Yes, but it requires coordination. Shared duct stacks mean the repair is not confined to your unit alone, and weak points in one section can pull contamination across shared returns. We schedule the work during building-approved hours, work within the access points your building designates, and document what we find so you can bring it to your HOA or building manager if the problem extends beyond your unit. Our standard written price and written guarantee apply to condo repairs the same as single-family homes.
Kent sits on the floor and hillsides of the Green River Valley, one of the most concentrated industrial logistics corridors in the Pacific Northwest. The valley’s temperature inversions trap diesel particulates and industrial dust at ground level, and residential HVAC systems pull that contamination in through return-air intakes. Renton does not sit in the same industrial-density geography. The result is faster contaminant accumulation inside Kent duct systems, which means small leaks and failures get dirtier, faster. Call (980) 447-2498 for an assessment of what is actually in your ducts.
It can be. Shared dryer vent stacks in Kent apartments accumulate lint that standard cleaning misses when the stack has a damaged section, a failed joint, or a restrictor bend. If the airflow restriction is caused by a separated or crushed stack section, that is a duct repair, not a cleaning. Our techs can camera the stack and identify whether the problem is lint accumulation, a mechanical failure in the run, or both, then give you a written price for the fix.
Yes. We repair ductwork connected to all major HVAC brands found in Kent homes, and we stock common connectors, collars, and flex duct locally so parts are not a delay. We run Rotobrush and Nikro equipment on our rigs, and our work is compatible with systems using Honeywell, Aprilaire, and Abatement Technologies components. The brand of your furnace does not determine whether we can repair the ductwork. Call (980) 447-2498 for a free estimate.
