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.
Air Duct Cleaning Company in Renton, WA
Air duct cleaning in Renton typically costs between $350 and $700 for a whole-home system, depending on home size and how long the ducts have gone without service. Renton isn’t like the hilltop suburbs around it. The Cedar River valley traps moisture, the housing stock runs heavy with 1950s and 1960s tract homes built for Boeing workers, and a lot of those original sheet-metal duct systems have never been opened, let alone cleaned. Call (980) 447-2498 for a written quote before any work begins.
Why Renton Homes Are Different
Renton sits at the south end of Lake Washington in the Cedar River valley, and that low-lying geography does something specific to forced-air systems: it keeps them damp. Temperature inversions sit over the valley floor more often than they do over Bellevue or Issaquah, and ground fog lingers. Indoor relative humidity stays elevated through most of the year, and that moisture finds its way into ductwork. We routinely open ducts in Renton Highlands homes and find mold at the boot registers nearest the slab, where older concrete foundations wick ground moisture into the lowest duct runs.
The housing stock compounds the problem. The Renton Highlands were built out primarily in the 1950s through 1970s to house Boeing employees. Those are post-WWII ranch and split-level homes, and a striking number still run on their original galvanized forced-air duct systems, now 50 to 70 years old. Flex-duct retrofits were added piecemeal over the decades, often poorly sealed, and deteriorated duct board sheds fiberglass particulate into living spaces. That means a Renton cleaning job is rarely a light dusting. It’s opening panels and finding decades of compacted lint, dust, and biological growth that has never been disturbed since the house was wired for its first furnace.
Our Main Renton Services
Most Renton homeowners call us about two things: cleaning the air ducts that have accumulated valley moisture and debris for decades, and clearing dryer vents that have become a fire hazard. Air duct repair is the third service that keeps coming up, especially in Highlands homes with failing flex-duct retrofits.
Air Duct Cleaning in Renton
Our Air Duct Cleaning in Renton service uses negative-pressure extraction to pull accumulated dust, mold spores, and fiberglass particulate out of the entire duct run, from the main plenum to every boot register. In Renton’s valley climate, that biological growth is the real target: it thrives in ductwork that stays damp year-round. One flat price per system, written before we start, covering every supply and return run in the house.

Dryer Vent Cleaning in Renton
Dryer Vent Cleaning in Renton removes the compacted lint that builds up faster in valley homes, where humid air makes lint cling to vent walls instead of blowing clear. It’s a genuine fire hazard, and a blocked vent also makes your dryer run longer on every load. We clean the full run from the dryer connection to the exterior termination point and verify exhaust flow when we’re done.

Air Duct Repair in Renton
When a Home Inspection turns up separated flex-duct, crushed returns, or duct board that’s deteriorated past the point of cleaning, Air Duct Repair in Renton covers the fix. Renton’s older homes are prone to duct board breakdown, and piecemeal retrofits from decades ago frequently show gaps and disconnections. Every repair is covered by a written guarantee, and if a covered repair fails, we return at no charge.

FAQs About Air Duct Cleaning Company in Renton
Most Renton neighborhoods can be scheduled within one to three business days. We don’t promise same-day arrival, because a real duct cleaning is a scheduled job that takes a few hours and should not be rushed. Call (980) 447-2498 and we’ll give you the next available window for your ZIP code.
No. Duct cleaning and dryer vent cleaning are internal system maintenance and don’t require HOA approval in any Renton community we’re aware of. The only exception would be a condo or townhome where the dryer vent termination runs through shared wall space; in those cases, we coordinate with property management as needed.
Moisture. Renton’s valley fog and lake proximity keep indoor humidity higher than the hilltop suburbs just a few miles east, which means duct systems here grow mold and mildew faster and hold onto lint and dust more stubbornly. The work frequently includes biological contamination treatment that drier cities don’t need. Call (980) 447-2498 for a quote specific to your home.

What Renton Customers Say
"Thorough job on all eleven vents and the main trunk. Took longer than the three hours they quoted, but he told me early and kept working. Air feels fresher."
- Meredith L."Tech arrived with a badge and a printed sheet of what he'd be doing. Ran a camera through the main trunk before and after so I could see the dust difference. Vents smell cleaner already."
- Gina R."Priced by the system, not by the vent, and he told me up front. No pressure to add the sanitizer and I said no without any fuss."
- Faith N.
