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 Cleaning Across DuPont
Air duct cleaning in DuPont, WA typically runs $400 – $700 for a full system on a standard single-family home, with the real driver being how many supply and return runs your particular floorplan has. Most DuPont jobs we do are on 1990s – 2000s construction built around the old DuPont Works company town, which means the flex duct is aging out at roughly the same rate neighborhood by neighborhood. We’re the crew that shows up with a written price before any duct is touched, names the tech before they knock, and sends you before-and-after photos of your own registers. Call (737) 727-2314 for a straight answer on what your system needs.
If you’re reading this from a two-story off Center Drive or a rambler near Clocktower Park, you already know the signs: dust settling back on furniture within days, a furnace filter that clogs faster than it should, rooms that never quite hold temperature. That’s what a DuPont system does when the trunk line and return runs haven’t been opened in 20 years.
Why Cardinal Air Duct Cleaning Is DuPont’s Preferred Air Duct Cleaning Company
DuPont homeowners call us because we tell them the truth about what’s in their ducts before we quote a number. We’re part of the Relay Home Co. family, founded 2005, and every location is independently owned and operated under The Relay Visibility Guarantee. That means a live trackable arrival window, before-and-after photo documentation of the work, and a digital invoice you can pay from a link. In DuPont specifically, Omar Haddad leads the crew, and he’s the one who makes sure the written price handed to you before work starts is the price on the invoice when we leave.
We don’t do per-vent pricing. We don’t add charges at the door. We don’t promise same-day scheduling during a Puget Sound cold snap or a spring pollen spike, because a proper camera inspection and full source removal takes the time it takes. What we do is straightforward: background-checked, uniformed technicians running Rotobrush agitation tools and Nikro HEPA-rated extraction, containment that keeps loosened debris out of your living room, and a 365-Day Done Right Promise covering every single job. If it isn’t right within a year, we come back and make it right.
Air Duct Repair in DuPont
Air Duct Repair in DuPont usually means reconnecting or replacing sections of 1990s-era builder flex duct that have sagged, torn, or separated at the joints, often in crawlspaces and attic runs off major roads like McNeil Street. In a DuPont two-story with a dozen-plus registers, a failed return connection quietly pulls dust and crawlspace air into the system every time the blower runs, which is why a “cleaning” alone doesn’t fix the symptom. Repairs on isolated sections typically run $150 – $450 depending on access and how many runs are compromised.
Reconnecting Leaking Return Runs
The most common repair call we get in DuPont is a return duct that has pulled loose from the plenum or torn along a seam. That gap means the system draws air from wherever it can, and what it draws in DuPont’s damp, pollen-heavy spring months ends up scattered across every surface in the house. We seal and refit those runs before cleaning so the system actually holds negative pressure.
Replacing Crushed or Torn Flex Duct
Builder-grade flex from the 1990s has a finite life, and in DuPont’s tight crawlspaces we regularly find sections crushed by stored boxes or torn by rodents. We cut out the bad section, fit new insulated flex to match the existing sizing, and mastic-seal the connections. A written guarantee comes with every repair, and if that repair fails, a second visit is free.
Ductwork Cleaning in DuPont
Ductwork Cleaning in DuPont is source removal: we’re not vacuuming at the registers, we’re opening the supply trunk and every branch run so the debris that has settled in the sagging low spots between joists actually leaves the system. On a 1990s DuPont home, that means running agitation tools through duct that was installed before current sealing standards existed, which is why we set up negative-pressure extraction at the air handler with a Nikro HEPA-rated unit holding the dust out of your living space. A full system cleaning on a standard DuPont single-family home runs $400 – $700, one flat price agreed before we start.
Full Trunk and Branch Line Cleaning
We clean the entire system, not just the registers you can reach. That includes the supply trunk, every branch line, all return runs, and the return plenum. On a DuPont two-story that’s usually 10 to 16 register openings, and the price doesn’t change because there are 14 instead of 11.
Air Handler and Blower Access
On DuPont’s aging original equipment, skipping the blower motor and air handler cabinet while calling it a duct cleaning is a waste of your money. A clean trunk line feeding a dust-caked blower just redeposits everything back into the supply ducts within a season. We open the air handler, clean the blower wheel and cabinet, and photograph that too.
Trusted Brands We Service in DuPont
We work on systems built around Honeywell, Aprilaire, and Guardsman filtration components, and we carry common DuPont replacement parts on the truck so a failed flex run or a torn boot doesn’t mean a second appointment. Our equipment fleet is professional-grade: Rotobrush rotary brush systems for mechanical agitation, Nikro HEPA-rated vacuums for true negative-pressure extraction, and Abatement Technologies containment units when a DuPont attic or crawlspace job needs isolation. If you’ve got a builder-grade system from the DuPont Works era that’s never been opened, we know what we’re going to find before we open it. That’s not a guess, it’s just rep count.
Common Air Duct Cleaning Problems We See in DuPont Homes
- Uniform housing age means uniform failure. Most of DuPont’s residential core was built in the 1990s – 2000s, so a whole street of homes hits duct-cleaning-needed status around the same time, with the same builder-grade flex duct and the same 20-plus-year-old original equipment. Either the ducts are dirty or they’re not, and on a Palisade Boulevard block, they usually are.
- Sagging flex duct in crawlspaces and attics. 1990s builder flex has loosened over two decades, creating low spots between joists where debris settles and never moves. A surface pass at the registers never reaches that, which is why we pull camera footage to show you what’s actually in there.
- Dust-caked blower motors. DuPont’s original air handlers are running on borrowed time, and a caked blower wheel just flings dust back into supply ducts within a season. We address the blower and cabinet as part of the job because skipping it makes the cleaning cosmetic.
- Pollen and marine air loading the filter. Between DuPont’s proximity to Puget Sound and the spring pollen spike from the surrounding evergreen canopy, your filter is working harder here than in inland Pierce County. That means the return side of the system pulls harder and draws more through any gap in the return runs.

FAQs About Air Duct Cleaning in DuPont
How much does air duct cleaning cost in DuPont, WA?
Most standard air duct cleanings in DuPont run $400 – $700 for a full system on a typical single-family home. That’s one flat price per system, written down before work begins, and it includes the supply trunk, every branch run, all return runs, the return plenum, and the air handler and blower cabinet. Repairs are priced separately and quoted before we start. Call (737) 727-2314 for an exact quote on your home; estimates are free.
How often do DuPont homes actually need their ducts cleaned?
Most DuPont homes built in the 1990s – 2000s go 15 – 20 years before the flex duct truly needs source removal, barring a renovation, a major water event, or a failed return connection pulling crawlspace air. If your home has never had the ducts opened and the original builder-grade flex is still in place, this is the window where that original equipment and ducting usually reaches end of usable condition. After a proper cleaning, every 3 – 5 years is reasonable for most households. Less if you have serious allergies or pets. If someone is quoting you an annual subscription, they’re quoting a habit, not a need.
When is duct cleaning NOT worth it?
If your system is less than five years old, was properly sealed at install, and your filter has been changed regularly, duct cleaning is probably not worth it yet. If the only symptom is a little dust on furniture in August, that’s likely a filter issue or a leaky return run, not a dirty trunk line. If someone wants to vacuum the registers for $99 and call it done, that’s not worth anything. We tell DuPont homeowners this because our reputation matters more than a job we shouldn’t have taken. Call (737) 727-2314 and Omar will tell you straight whether your system needs cleaning or a repair instead.
Do you use NADCA standards and negative pressure, or just a shop vac?
We clean to NADCA standards using true negative-pressure extraction, which means the loosened debris goes straight into a HEPA-filtered Nikro vacuum unit at the air handler instead of back into your living room. A shop vac at the register is surface-level cosmetic work, and on DuPont’s 1990s-era flex duct, the debris that matters sits in the sagging low spots between joists where a surface pass never reaches. We use Rotobrush agitation tools to break that debris free while the Nikro unit holds negative pressure on the line, and we photograph everything before we call the job done.
Why won’t you promise same-day air duct cleaning?
A proper duct cleaning in DuPont is not a two-hour job when you’re opening the trunk line, running agitation tools through every branch, cleaning the blower motor and cabinet, and photographing every register. During a Puget Sound cold snap or a spring pollen spike, promising same-day scheduling means either cutting the job short or running a crew that hasn’t done a proper camera inspection. We’d rather tell you a straight arrival window you can track on your phone than hand you a rushed job. Call (737) 727-2314 and we’ll get you on the schedule with a live trackable arrival time.
