Dryer Vent Cleaning in Kirkland

Dryer Vent Cleaning in Kirkland, WA

The part of a dryer vent nobody looks at is the hood outside. On the hillsides above Lake Washington it spends its life in damp air off the water and the Juanita Bay wetlands. We inspect the cage and the flap on every visit and photograph what is there.

Before and after a WindowWorks dryer vent cleaning on the Eastside, a lint-packed vent cleared to a clean, clear interior

A cage that has broken away is an open door for birds and rodents looking for a warm dry hole. A flap that has stopped moving does the opposite and seals lint and moisture inside the line. Both turn up on the older houses around Houghton and Rose Hill, on the newer builds up Juanita and Finn Hill, and on everything in between from Totem Lake to Bridle Trails.

Inside the line the work is a rotating brush and compressed air, driving the lint out through the exterior. The airflow gets checked afterward and a second camera pass confirms the run is open. If the cage is broken or missing, a pest guard can go on in its place.

Kirkland questions

Something is nesting in our dryer vent. Now what?
We photograph what is in there and tell you what clearing it involves. Active nest removal is quoted separately from the cleaning. Once the line is clear, a guard on the outside keeps the next one from moving in.
Our vent hood broke off. Can we just leave it open?
An open termination is how birds and rodents get in. A guard goes on in place of the broken hood and keeps them out while the exhaust flows freely. It is the kind of thing worth handling on the same visit.

Before and after

The difference, on real jobs.

  • Before and after WindowWorks clearing a dryer vent that a bird had died inside, the duct cleaned back to bare galvanized metal on the Eastside
    A bird got into this vent and died in it. The duct came back to bare metal.
  • Before and after WindowWorks clearing matted lint packed along the wall of a dryer duct on the Eastside
    Matted lint packed along the duct wall. That is the fuel, and it is what the lint screen never catches.
  • Before and after a WindowWorks dryer vent cleaning, a lint-fouled duct cleared to clean bare metal, Eastside Seattle.

Real jobs, up close.

  • A dryer transition duct behind the machine packed solid with gray lint on an Eastside Seattle job

    The transition duct behind the dryer, packed solid. This is the part the lint screen never catches.

  • Heavy wet, matted lint pulled out of a dryer vent on the cleaning brush

    Wet, matted lint on the brush. The airflow was so choked that the moisture had nowhere to go, so it piled up damp inside the duct.

  • The pile of lint removed from one dryer vent, in the truck bed with a marker for scale

    What came out of one vent, in the truck with a marker for scale. All of it was fuel sitting in the line.

  • An exterior dryer vent bird and rodent guard clogged with lint on an Eastside Seattle home

    The exterior guard, clogged. A damaged or missing cover is an open invitation for birds and rodents, so we can fit a screened guard.

Why it matters

The problem this solves.

Lint packs into the duct you never see, so the dryer runs longer, hotter, and wears out early. Slow dry times are usually airflow, not age, and packed lint is a leading contributor to dryer fires.

National Fire Protection Association (NFPA) logo

National Fire Protection Association

The NFPA is the U.S. nonprofit behind the fire codes and standards used across the country. It counted an average of 13,820 home fires a year involving clothes dryers from 2014 to 2018, and it recommends clearing lint from the dryer vent at least once a year, or having a dryer lint removal service do it.

What the data says

Thousands of dryer fires a year, and the top cause is lint.

This is not a scare number, it is a maintenance number. Federal estimates put residential dryer fires in the thousands every year, and the single leading factor is the one thing a homeowner can actually control.

5,600

residential dryer fires a year, averaged across 2018 to 2021.

Residential structure fires, clothes dryers only. These estimates exclude confined fires and intentionally set fires, which is why they run lower than the National Fire Protection Association's figure of 13,820 home fires a year for 2014 to 2018: that one counts confined fires too. The two are different measures of the same problem, not a disagreement.

Averaged from US Consumer Product Safety Commission, Residential Fire Loss Estimates (2018-2020 edition, August 2023; 2019-2021 edition, July 2024).

What matters more than the count is the cause. The US Fire Administration found failure to clean was the leading factor in home dryer fires from 2018 to 2020, at 31 percent. Not a faulty machine, not bad wiring. Lint nobody removed.

How we do it

Our approach.

A camera inspection first shows the line's condition and locates the restriction. We open the run at both ends, then a rotating brush and compressed air work the lint out toward the exterior, never back into your laundry room. An airflow check and a second camera pass verify the result, documented with photos.

  • Camera inspection before and after
  • Airflow verified after cleaning
  • Pest cage and vent flap inspected
  • Duct checked for kinks, crushes, disconnections, wear
  • Blockage severity and location assessed
  • Photo documentation of findings

New service

Catch the plastic before it leaves your house.

We fit a filter to your washing machine drain and clean it out once a year, so the synthetic fibers your clothes shed end up in a bag you can empty instead of in Puget Sound. We are already in your laundry room for the dryer vent, and the washer is the other half of the problem.

  • 135 Grams a Year

    What a household in the US or Canada can send down the drain in a year. Most of a modern wardrobe is plastic: fleece, activewear, swimwear, most sheets and towels, and the lining of almost every jacket. Every wash shakes fragments loose.

    Share of the microplastics found in Puget Sound sediment in a 2025 survey that were fibers rather than fragments. Nothing downstream of your house was built to stop a fiber twelve microns wide.

    What We Install

    A 100 micron laundry filter that mounts on the wall beside your machine, made in the USA by Wexco of Milaca, Minnesota. No electricity, no batteries, no app.

    It clamps onto the discharge hose your machine already has, so nothing is cut and it comes off without a trace. Rated to 25 gallons a minute, far above what a residential washer discharges, so the drain cycle does not slow down. Limited lifetime warranty on the housing, two years on our workmanship, and we test a full drain cycle before we leave.

  • Dimension diagram for the laundry filter, marked 16 inches tall, 9 inches wide, and protruding 8 inches from the wallManufacturer's diagram.

    Will It Fit Your Laundry Room?

    You need roughly 8 inches of clear wall above the mounting point so the lid lifts off, a reachable standpipe, wall box or laundry sink, and enough room to stand at the machine and empty a bag.

    In the largest field study of these filters, about one home in five could not be fitted. We check first, and there is no charge if yours will not take one. Send a photo of the space behind your washer and we will tell you.

The honest answer

How well does it work, and what we won't claim.

Independent testing has measured capture anywhere from about 25 to 90 percent by weight. Anyone quoting you one number has picked the test that flatters it. The high end is polyester through a fine mesh, and nylon has measured as low as 19 percent. The rest comes down to whether the filter gets cleaned, because a full one keeps draining but stops catching, and nothing looks wrong. That is why we sell the service and not just the hardware.

Your treatment plant is good at this, removing more than 90 percent and often well over 99. Two things still get through. Volume first: one Glasgow plant discharged an estimated 65 million particles a day after removing 98.4 percent of them. Then destination, because the fibers a plant does catch are not destroyed. Between 63 and 80 percent settle into sludge, which becomes biosolids and goes onto farmland.

One last thing, because you will see it claimed elsewhere. Microplastics have been found in human blood and tissue, but nobody has established that they harm people, and the World Health Organization found no apparent risk from those in drinking water at current levels. We will not tell you otherwise to sell you a filter. Keeping the fibers out of the water is reason enough.

Why WindowWorks

Who shows up matters.

This service happens inside your home. Who we send matters as much as what they clear out of the duct.

Anyone can rent a pressure washer. After 20+ years on Eastside exteriors, and a 4.9 rating across 300+ reviews, we can tell you the real difference is the person holding the wand: what they know, how they were trained, and whether the company behind them takes care of them. We take care of our techs, so they take care of your property.

A WindowWorks technician training on the mock roof at our facility

  • Background-checked

    Every technician is background-checked before they ever step onto a customer's property.

  • Certified, skill by skill

    Our crews earn certification across 369 individual skills in 10 categories, each one signed off by an evaluator, never just by clocking time.

  • Paid like professionals

    A living wage, healthcare, and dental. People who are treated well do careful work, and they stay, so you see the same faces.

  • Licensed, bonded, and insured

    With OSHA-aligned safety training for the at-height work. If someone is on your roof, they are trained and covered for exactly that.

  • Method matched to the surface

    Soft wash where pressure would damage, hot water where cold cannot lift, the right chemistry for the stain. The method follows the surface, not the other way around.

  • Documented before and after

    Every job is photographed before and after, so you can see exactly what changed and keep it on file.

Common questions

Good to know.

Isn't emptying the lint trap enough?

No. Lint packs the vent line, the lint trap housing below the screen, and the flexible duct behind the dryer, the part that crushes and wears fastest; Premium deep cleans the housing and exhaust port and replaces that duct.

What is the difference between Deluxe and Premium?

Deluxe is camera inspection plus full cleaning of the vent line, ductwork, and exterior termination. Premium adds deep cleans of the exhaust port and lint trap housing, light cleaning around the dryer, and a new transition duct; non-standard fittings get confirmed with you first.

Will this fix my dryer?

It restores airflow, which is what slow dry times usually are. It does not repair damaged ducting or internal dryer problems; any duct damage gets documented with photos and a recommendation.

What do you inspect on every visit?

The whole system: pest cage, vent flap, duct condition, and any blockage's severity and location, all photographed. A stuck flap means pests and moisture or blocked airflow; a broken cage is an open door for nesting.

What if you find a nest or damaged duct?

Severe blockages can take extra work or a repair visit, and active nest removal is quoted separately. You get a photo report either way, and if the exterior cage is broken or missing, we can install a pest mitigator.

Can you reach a rooftop or second-story vent?

Usually, yes; rooftop and high-wall vents are the same trained, insured at-height work our crews do daily. Ladder access above the ground floor adds to the price, and tight chases or finished construction can limit how far the inspection reaches.

Will the microfiber filter slow my washing machine's drain?

No. It is rated to handle up to 25 gallons per minute, far above what a residential washer discharges. What does cause slow draining is a filter nobody has cleaned in six months, which is what the annual service is for.

Do you have to cut into my plumbing to fit it?

No. It clamps onto the discharge hose your machine already has and drains into your existing standpipe, wall box, or laundry sink. Nothing is cut, nothing is permanent, and it comes off without a trace.

Will a filter fit my laundry room?

You need roughly 8 inches of clear wall above the mounting point so the lid lifts off, a reachable standpipe or sink, and room to stand and empty a bag. In the largest field study of these filters about one home in five could not be fitted. We check first, and there is no charge if yours will not take one.

How often does the filter need cleaning?

Rinse the bag every 8 to 10 loads, which is every one to three weeks for most households, and the bag itself lasts one to two years. Liquid fabric softener leaves a film that blinds the mesh, so if you use it expect to clean more often. We tell people that before we install, not after.

We're on septic. Does the filter help?

A septic system has no step designed to capture synthetic microfiber, and there is very little research on what happens to it in a drainfield. Catching it at the machine is the only certain way to keep it out. We are not going to claim it will save your drainfield, because nobody has shown that.
