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.

Call (361) 326-5060 for a free written estimate.
We’ve worked on enough homes around Lake Morton and the surrounding wetland edges to know the local profile: private wells, septic systems, and long dryer runs through crawlspaces that were sized for 1980s laundry loads, not modern high-capacity machines. That combination produces a specific kind of blockage you won’t find in Kent or Covington. Our Dryer Vent Cleaning team carries the agitation tools and camera gear to clear it properly, not just blow compressed air through and call it done.
Why Hollis Air Duct Cleaning Is Lake Morton-Berrydale’s Preferred Dryer Vent Cleaning Company
Hollis Air Duct Cleaning has been part of the Garrison Partners family since 2004. We operate under The Garrison Standard, which means written prices before any work starts, background-checked uniformed technicians, and a 365-Day Done Right Promise backed in writing on every job. In Lake Morton-Berrydale, that standard matters because the work is often invisible: a 24-foot run through an unlit crawlspace, a shared termination wall behind landscaping, a low elbow under a septic drain field access. You need a crew that documents what they found and what they did, not one who disappears after the van leaves.
Our technicians know the local housing stock. Mid-century ranches off SE Lake Morton Drive, split-levels from the 1970s with original vent routing, newer custom builds on acreage with heat-pump air handlers and extended dryer runs to reach the nearest exterior wall. Each configuration gets a written scope and a written price before we touch anything. If the repair fails within a year, we return and make it right at no charge, including a free second visit. That’s the 365-Day Done Right Promise, and it’s on every Lake Morton-Berrydale invoice.
Phones are answered by a live person 24 hours a day, 7 days a week. No callback queues, no “leave a message and we’ll get back to you Monday.” Scheduling is coordinated from our Seattle office, and crews serve Lake Morton-Berrydale locally with Rotobrush rotary brush systems and Nikro negative-air machines, the same tools commercial crews use. You know who’s arriving, when, and what it’ll cost. That’s The Garrison Code in practice.
Dryer Vent Cleaning Service in Lake Morton-Berrydale
Dryer Vent Cleaning Service in Lake Morton-Berrydale addresses a specific regional problem: the well-water mineral dust and septic-adjacent humidity that bind with lint into a dense, clay-like paste clinging to vent walls. Standard lint traps catch surface debris. They don’t catch what hardens in the low elbows of a 20-foot run or packs the exterior flapper into a solid mat. Our process starts with a camera inspection so you see the blockage, followed by mechanical agitation with Rotobrush tools to break the deposit loose, then negative-air extraction to pull it out completely. We finish with airflow verification and a written report.
A typical single-run Dryer Vent Cleaning Service in Lake Morton-Berrydale costs $180 – $240. Homes with long runs over 15 feet, multiple bends, or shared termination points run $260 – $340. Multi-system properties with two or more dryers start at $320 and scale by run count, not by vent cap. The price is written before we start. It does not move at the door.
When to Schedule Cleaning
Watch for longer dry cycles, a hot laundry room, or a musty wet-cardboard smell after loads finish. In Lake Morton-Berrydale, these symptoms often appear after wet winters when closed-up houses trap septic-adjacent humidity in the vent pathway. If your dryer’s taking more than 45 minutes for a standard load, the run’s likely restricted.
What the Job Includes
We inspect the full run with a borescope, clean with rotary brush and negative-air extraction, verify airflow with an anemometer, and document before-and-after photos on your invoice. For homes near the Lake Morton shoreline or surrounding wetlands, we also check the termination hood for mold seeding, common after prolonged dampness.
Dryer Vent Installation in Lake Morton-Berrydale
Dryer Vent Installation in Lake Morton-Berrydale often means correcting original runs that were never adequate for the home’s current use. Many mid-to-late 20th-century houses here were built with 3-inch ducting or flexible transition hose buried in walls, neither of which handles modern dryer output or the local lint profile. We replace with rigid 4-inch galvanized duct, proper slope for condensation drainage, and exterior terminations sized for airflow. For acreage homes with distant utility rooms, we design longer runs with inline booster fans where code allows.
Standard Dryer Vent Installation in Lake Morton-Berrydale runs $340 – $580 for a single run with wall termination. Rerouting through crawlspace or attic space, adding a booster fan for extended runs, or installing bird guard and pest-proof cap adds $120 – $280. Multi-run properties with shared exterior walls require custom scope and written pricing before work begins.
Code and Safety Compliance
King County requires rigid metal duct for concealed dryer vent runs, with maximum length based on elbows and termination type. We pull permits when required and inspect to code. For homes with heat-pump air handlers in unconditioned attics, we coordinate vent routing to avoid conflict with refrigerant lines or duct sealing mastic work.
Bird Guard and Pest Protection
Terminations without screens invite starlings and rodents, common around the large lots and wetland margins near Lake Morton. We install Guardsman-brand bird guards and replacement vent caps with integrated pest barriers, not mesh that clogs with lint. Annual cleaning still matters, but the pathway stays protected between visits.
Trusted Brands We Service in Lake Morton-Berrydale
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for extraction, and filtration products from Honeywell, Aprilaire, and Guardsman. We stock common vent caps, bird guards, and rigid duct fittings for Lake Morton-Berrydale properties, so most repairs don’t wait on parts. For heat-pump homes with Aprilaire media filters or Honeywell MERV-rated systems, we verify that dryer vent airflow doesn’t compromise the HVAC air balance. That’s a specific check we run on acreage properties where the laundry room and air handler share a mechanical zone.
Common Dryer Vent Cleaning Problems We See in Lake Morton-Berrydale Homes
- Mineral-dust lint paste in long runs. Well-water mineral dust binds with septic-adjacent humidity to form a dense deposit that standard shop-vacs won’t touch. We find it packed into low elbows on 20-foot-plus runs in original-build homes off SE Lake Morton Drive and surrounding roads.
- Exterior flapper packed solid. Homeowners check the lint trap, assume the run’s clear, and never inspect the termination hood. After wet winters, the flapper becomes a solid mat of damp lint and mineral dust that stops airflow entirely. Cycle times creep up for months before anyone notices.
- Cross-contamination on shared vent walls. Multiple-system houses, common on acreage properties, often route two dryers or a dryer plus bath exhaust through one exterior penetration. One system’s backpressure loads the other with lint. Single-run cleaning misses it; camera inspection catches it.
- Mold seeding in termination hoods after wet winters. The Pacific Northwest’s prolonged dampness, combined with septic-adjacent humidity and closed-up houses, creates conditions where lint mats grow mildew. The laundry room smells musty even when the dryer’s off. Agitation cleaning plus antimicrobial treatment on the hood solves it.

FAQs About Dryer Vent Cleaning in Lake Morton-Berrydale
Yes. We price by dryer vent run, not by house size or HVAC count. A single dryer vent run in Lake Morton-Berrydale costs $180 – $240; a second run adds $140 – $200. Your three HVAC systems don’t affect dryer vent pricing unless they share a termination wall, which we’d note during inspection and address in the written scope. Call (361) 326-5060 for an exact quote – estimates are free.
The combination of private well water, septic-adjacent humidity, and the Pacific Northwest’s prolonged dampness creates a specific lint profile here that traps moisture and seeds mildew in the termination hood. Kent’s municipal water and sewer infrastructure doesn’t produce the same mineral-dust-and-humidity binding. Our Lake Morton-Berrydale process includes antimicrobial treatment on the hood when we find mold indicators. Call (361) 326-5060 for an exact quote – estimates are free.
Yes. Many newer Lake Morton-Berrydale builds on acreage use heat pumps with ducted air handlers, and the dryer vent routing is often independent. We inspect for cross-contamination between systems, verify that dryer backpressure doesn’t affect HVAC airflow, and document both pathways. The cleaning process is the same; the inspection protocol is more thorough. Call (361) 326-5060 for an exact quote – estimates are free.
We show you. Every Lake Morton-Berrydale job includes borescope photos of the full run before and after cleaning, plus anemometer readings that verify airflow at the termination. On a large-lot property off SE Lake Morton Drive, we pulled a 24-foot run that had been “cleaning fine” for years; camera inspection showed the exterior flapper packed solid, and our tech extracted a mineral-dust-and-lint mat so thick the homeowner’s Honeywell MERV 11 filter had been doing nothing for the dryer side. After agitation tools cleared the run and we verified airflow, cycle times dropped back to normal and the laundry room lost its wet-cardboard smell. You get the photos and the numbers on your invoice. Call (361) 326-5060 for an exact quote – estimates are free.
For many Lake Morton-Berrydale homes, yes. The wet winters and septic-adjacent humidity mean lint mats form faster and denser than in drier climates. Homes near the Lake Morton shoreline or surrounding wetlands, especially those closed up for months, often show elevated moisture in the vent pathway. We recommend annual inspection with cleaning every 12 – 18 months for standard use, or annually for households with heavy laundry loads or long runs. Call (361) 326-5060 for an exact quote – estimates are free.
