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.
Fast, Reliable Dryer Vent Cleaning Across Renton
Dryer vent cleaning in Renton typically costs $150-$280 for a standard single-family home, with most appointments completed in 60-90 minutes and scheduled within a few business days. We’re Morton’s Air Duct Cleaning, and our Dryer Vent Cleaning team has been working the valley floor and hillside neighborhoods of Renton since 2005. Dispatch and scheduling run through our Seattle office, but the crews that roll into the Highlands, Talbot Hill, and the rural edges near Maple Valley are local technicians who know the difference between a 1962 crawl-space ranch and a Southport townhome before they step out of the van.

Why Morton’s Air Duct Cleaning Is Renton’s Preferred Dryer Vent Cleaning Company
We’ve built our reputation in Renton by treating every home like the technician’s own. That means shoe covers and drop cloths from the moment we walk in, quiet tools when there’s a toddler napping down the hall, and a written price agreed before anyone touches a tool. Our 365-Day Done Right Promise covers every job, not just the ones where a customer asks.
Our technicians are background-checked, uniformed, and trained to the Cedarwell C.A.R.E. values. They arrive with professional-grade equipment from Nikro and Rotobrush, not rental-shop vacuums. Every completed job includes a photo of the clean-up before the crew leaves, so you see the result, not just hear about it. And when you call (323) 918-4345, a live person answers, 24/7.
We know Renton’s housing stock. The Boeing-era crawl-space homes in the Highlands and North Renton weren’t built with modern dryer vent standards. Flex duct retrofitted into damp, shaded crawl spaces creates failure patterns we see weekly and fix properly. That local knowledge means we diagnose faster and fix it right the first time.
Dryer Vent Installation in Renton
Dryer Vent Installation in Renton addresses a specific problem: the original vent runs in 1950s-1970s homes were never designed for today’s dryer loads, and many have been patched together with flex duct that sags, crushes, or terminates in dangerous locations. A proper installation replaces the entire run with smooth metal duct, corrects the termination point to a code-compliant exterior hood, and ensures adequate airflow for modern appliance capacity. In Renton, where crawl-space moisture and shaded exterior walls compound every airflow problem, this isn’t cosmetic. It’s structural to the safety and efficiency of the system. Typical Dryer Vent Installation in Renton runs $350-$650 depending on run length, access difficulty, and whether we’re routing through a crawl space or an interior wall.
When Installation Beats Repair
We recommend full replacement when the existing run uses multiple flex-duct sections, when the termination hood is recessed into a moisture-trapped crawl zone, or when camera inspection shows crush damage or separation at joints. In Talbot Hill split-levels, we often find the original 4-inch run was later adapted with 3-inch flex to accommodate a relocated laundry. That never works. We pull it all and start clean.
Metal Duct and Proper Termination
Every installation we complete uses smooth metal duct with sealed joints, supported every 4 feet to prevent sag. The exterior hood gets a backdraft damper and a bird guard where needed. In Renton’s damp crawl spaces, we spec termination points that avoid shaded, low-ventilation zones. The difference in airflow and lint accumulation is immediate and measurable.
Dryer Vent Repair in Renton
Dryer Vent Repair in Renton covers the partial failures that don’t require full replacement but absolutely require professional attention: separated joints in crawl spaces, damaged termination hoods, crushed duct from storage or pest intrusion, and backdraft dampers seized shut with lint and biological growth. Most repairs run $180-$340 in the Renton market, with same-visit completion when parts are on the truck. We carry common hoods, dampers, and transition fittings for the brands we service, including Honeywell and Aprilaire components.
Crawl-Space Joint Separation
In Renton Highlands and North Renton crawl spaces, we regularly find flex-duct joints that have pulled apart at the clamps. The damp environment degrades the vinyl tape or zip-tie repairs homeowners attempted years ago. We rejoin with proper mechanical fasteners and seal with mastic rated for the temperature and moisture exposure. Then we support the line so it doesn’t sag again.
Hood and Damper Replacement
The exterior hood is where Renton’s climate does its damage. Shaded north-facing walls, persistent valley humidity, and lint combine to grow mold that seizes the flap. A stuck flap means moist exhaust air back-drafts into the laundry or crawl space. We replace with corrosion-resistant hoods and verify free-swinging operation before we leave.
Trusted Brands We Service in Renton
Our trucks stock parts and fittings for the major dryer vent and HVAC component brands we encounter in Renton homes: Honeywell dampers and controls, Aprilaire ventilation accessories, and Abatement Technologies HEPA filtration for our negative-pressure cleaning setups. We carry Nikro agitation tools and camera inspection gear for source-removal work that actually clears the line, not just pushes lint deeper. For termination hardware, we use Guardsman hoods and bird guards where the local bird pressure warrants them. Having parts on the truck means most repairs finish in one visit, not two. Rural properties on the Renton edge with longer service drives especially benefit from that efficiency.
Common Dryer Vent Cleaning Problems We See in Renton Homes
- Seized exterior hoods on shaded crawl-space walls. In the Highlands and Talbot Hill, dryer vents often terminate into damp, shaded zones where the flap jams with lint and biological growth. The dryer still runs, but moist air back-drafts into the home, raising humidity and creating that musty laundry smell.
- Sagged flex duct with packed lint mats. Retrofitted flex duct in 1960s crawl spaces develops low spots where lint and condensate combine into dense, felt-like blockages. Standard brushing from the laundry room misses the packed material entirely.
- Crushed or kinked runs from storage or pest activity. Crawl-space lines get damaged by seasonal storage, rodent pressure, or simply decades of vibration. A partially crushed 4-inch line behaves like a 2-inch line, doubling dry times and overheating the appliance.
- Excessive lint loading on rural-edge properties. Homes near unpaved roads and open land in outer Renton see heavier dust and pollen intake, which combines with fabric lint to accelerate buildup. These properties need shorter cleaning intervals than sheltered in-town homes.

FAQs About Dryer Vent Cleaning in Renton
Every 12-18 months for rural-edge properties with unpaved road exposure, wood heat, or outbuilding laundry setups. The dust and pollen loading is significantly higher than in sheltered neighborhoods, and lint traps don’t catch the fine particulate that accelerates buildup. Call (323) 918-4345 to set up a schedule that matches your property’s conditions.
The combination of original flex-duct retrofit, damp crawl-space air, and shaded exterior terminations creates a condensate-plus-lint failure pattern unique to these 1950s-1970s homes. Newer construction uses smooth metal duct, proper vapor barriers, and ventilated termination points that stay drier and clearer. We treat every Highlands vent as a moisture-and-lint problem, not just a lint problem.
Everything. A hood clogged with lint and biological growth forces moist exhaust air back into the crawl space or laundry room, which is why some Renton homeowners smell mustiness even after clearing the lint trap. Our cleaning includes hood inspection, flap function test, and replacement if the damper won’t swing free. The hood is half the system.
Yes. We schedule those properties with full equipment loads and adequate time blocks so the job gets the same camera-verified source removal as an in-town home. We don’t do trap-and-hose blow-outs that leave buried lint pathways intact. The written price is agreed before we start, regardless of drive time.
The lint trap catches roughly 60% of lint. The rest enters the duct, where it accumulates, restricts airflow, extends dry times, and creates fire risk. In Renton’s humid crawl spaces, that lint also holds moisture against duct walls, accelerating corrosion and biological growth. Cleaning the trap helps. Cleaning the duct is essential.
