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.

Why We’re Duvall’s Go-To for Honest Dryer Vent Work
Duvall isn’t Redmond or Woodinville. The housing stock here mixes 1990s and 2000s Snoqualmie Valley plat homes with older valley-floor houses, and a lot of those dryers sit on exterior walls with long, elbow-heavy vent runs that terminate at or near the roof. That’s a configuration that traps lint far from the trap we can all reach, and it demands a different approach than a quick once-over. We know these homes because we work in them. The Cherry Valley rises, the older streets near the river, the newer developments up toward the ridge. Every Duvall job gets the same standard: a written price before we touch a single duct.
Cardinal operates under The Relay Visibility Guarantee, which means every Duvall booking includes a live trackable arrival time, before-and-after photo documentation, and a digital invoice you can pay from your phone. Founded in 2005, the Relay Home Co. family has held every location, including this one, to the same standard. That’s not a slogan. It’s the operating system. Omar Haddad leads our team, and when you book with Cardinal, you’ll know the technician’s name before they park on your street.
We answer calls with a live person 24/7. Not an answering service that takes a message. A person. If you call at 6 p.m. after the dryer has been running two cycles and the laundry room still feels humid, someone picks up.
Dryer Vent Repair in Duvall
Dryer Vent Repair in Duvall means fixing a vent run that is no longer moving air the way it should, whether that’s a crushed section behind the dryer, a disconnected joint inside the wall, a damaged roof cap, or a vent that was never properly supported in the first place. Older valley-floor homes in Duvall often have foil or vinyl venting that has sagged, torn, or been pinched behind the dryer, and newer plat homes sometimes have vent runs with so many elbows that airflow is compromised from day one. Repair work, depending on what we find, runs $80 – $180 for typical fixes like cap replacement or joint resealing. Full reroutes cost more, and we’ll show you a written price before any work begins.
Common Repair Work We Handle
Roof and wall cap replacement is the most frequent repair we see on Duvall’s two-story vent runs. Caps crack from sun exposure, get clogged with debris, or let birds and rodents nest inside. We replace them with proper backdraft-damped caps and can add bird guards where needed.
We also see disconnected joints inside walls, especially in 1990s construction where the original vent was plastic and the joints were taped rather than screwed. A disconnected joint means your dryer is blowing moist, lint-laden air into the wall cavity. That’s not a cleaning problem, it’s a repair problem, and it’s one we diagnose with a camera before quoting anything.
What a Camera Inspection Actually Shows
You can’t see past the first elbow from the laundry room, so we run a small camera through the vent before we clean or repair anything. In Duvall, this inspection has repeatedly revealed lint packed at the first elbow even in homes where the trap was emptied after every single load. The camera tells us what’s actually there, not what we assume is there.
Dryer Vent Cleaning Company in Duvall
Dryer Vent Cleaning Company in Duvall is what we are, but we’d rather you think of us as the team that gives you a written price, shows up when we said we would, cleans the vent at the source, and proves it with photos of your own ductwork. A standard cleaning for a Duvall home runs $140 – $230, one flat price per system. We don’t price per vent, per foot, or per elbow. The price you agree to over the phone is the price you pay, even if your vent run climbs two stories and exits at the roofline with three elbows in between. That’s the difference between an estimate and a promise.
The Actual Cleaning Process
We set up professional-grade equipment, including Rotobrush rotary brush systems and Nikro HEPA vacuums, then create negative pressure at the vent opening. Negative-pressure extraction means the loosened lint and debris get pulled directly into the HEPA-filtered vacuum rather than blown back into your laundry room. We agitate the inside of the run with rotary tools to break up matted lint, then work the full length of the vent from the dryer connection to the exterior termination. On multi-story Duvall vent runs, we may work from both ends to make sure nothing is left behind.
Before-and-After Proof
Every Duvall dryer vent cleaning ends the same way: you get original before-and-after photographs of your own vent interior, not stock images, not a generic “after” shot from someone else’s house. If we cleaned it, we documented it. That’s part of The Relay Standard, and it applies to every booking without exception.
What a Duvall Dryer Vent Cleaning Actually Looks Like
On a recent call in Duvall’s Cherry Valley area, our tech found a 2003-built home whose dryer vent run climbed two stories before exiting at the roofline. The homeowner had been emptying the trap religiously, but a camera inspection showed a packed lint pathway at the first elbow. We set up negative pressure with HEPA filtration, used agitation tools to break the matted lint loose, and pulled it through source removal. The blower motor load on the dryer dropped noticeably on the follow-up test. Before we left, we handed the homeowner before-and-after photographs of their own vent run. Not a stock image, not a generic diagram. Their actual duct, top to bottom.
That’s the difference with Dryer Vent Cleaning done properly. A quick shop-vac pass over the wall connection leaves most of the lint exactly where it was. Source removal pulls it out entirely.
We serve all of Duvall with this same standard. No shortcuts, no per-vent games, no price changes at the door.

Common Dryer Vent Cleaning Problems We See in Duvall Homes
- Long roof-terminated vent runs that never get camera-inspected. Many Duvall homes built in the 1990s and 2000s have dryer vents that run uphill for eight to fifteen feet before exiting at the roofline. Lint settles in the low spots and at each elbow, and without a camera, nobody ever sees it.
- Disconnected joints inside wall cavities. Plastic or foil venting from that era was often taped rather than screwed. Over time the tape dries out and the joints separate, sending moist air and lint into the wall instead of outside.
- Bird and rodent nests at the exterior termination. Duvall’s tree cover means open vent caps quickly become nesting sites. We remove the nest, clean the vent, and install a bird guard so it doesn’t happen again.
- Excessively long runs with too many elbows. Some newer plat homes route dryer vents through multiple turns to reach a wall or roof that meets HOA aesthetic requirements. Every elbow reduces airflow and traps lint. If a reroute would solve the problem, we’ll tell you what that costs up front.

FAQs About Dryer Vent Cleaning in Duvall
For most Duvall homes, once every 12 to 18 months is the honest answer. If your vent run is long, elbow-heavy, or roof-terminated, annual cleaning is the safer schedule. If you have a short, straight run to an exterior wall and you empty the lint trap every load, you can probably stretch it to two years. The only way to know for sure is a camera inspection. Call (737) 727-2314 and we’ll help you figure out if you need service now or can wait.
Per system. One flat price for the entire dryer vent run, agreed before we start, and it does not change once we see the actual lint pathway. We don’t price per vent, per foot, or per elbow, and we never come back with a higher number at the door. The price we quote over the phone is the price you pay. Call (737) 727-2314 for an exact quote.
We start with a camera inspection to see the real condition of the vent. Then we set up a Nikro HEPA vacuum at the vent opening to create negative pressure, agitate the interior with Rotobrush rotary tools, and pull the loosened lint out at the source so it doesn’t redistribute into your laundry room. We finish with before-and-after photos of your own ductwork. Most Duvall jobs take one to two hours. Call (737) 727-2314 to schedule yours.
Yes. If the camera inspection reveals a disconnected joint, a crushed section, a failed cap, or a nest, we can usually repair it on the spot because we stock common parts in the van.

Call (737) 727-2314 to talk through what you’re seeing.
We don’t promise same-day service because we don’t want to rush a job and leave lint behind.
