Air Duct Cleaning in Shoreline - One Flat Price, Before-and-After Photos

Air Duct Cleaning in Shoreline, WA

Dryer vent cleaning in Shoreline homes is a different job than it is in most of King County. The 1950s-to-1970s ranch and split-level homes that dominate Shoreline’s neighborhoods often have long, uninsulated vent runs that snake through unheated crawl spaces, and the marine air keeps lint damp and sticky inside those pipes almost year round. If your dryer has a vent run longer than ten feet, or the flapper doesn’t seat fully at the roof cap, you’re already dealing with the conditions that make Shoreline vent fires and restricted airflow a regular call for us. Call (806) 606-6902 for a written price before any work starts.

Why Shoreline Homes Are Different

Shoreline’s housing stock was not built around forced-air heating. Most of the homes from roughly 1950 to 1975 started as unincorporated King County tracts with oil heat or electric baseboards, then got retrofitted with gas forced-air systems during the 1970s and 1980s. Those retrofit duct runs were often shoehorned into crawl spaces and wall cavities with nonstandard bends, duct tape joints that dried out years ago, and fiberglass liner that has been slowly shedding particles into the air stream for decades. The result is a network of ducts that was never engineered for the airflow it now carries.

Then there is the marine humidity. Shoreline sits in the Puget Sound lowlands, where winter cloud cover and onshore flow push crawl-space relative humidity above 80% for months at a time. In neighborhoods like Ridgecrest, Briarcrest, and Paramount Park, that moisture migrates through unsealed penetrations and settles inside cold metal ductwork every night. Dust mites thrive in those conditions. Mold spores that would stay dormant in a drier inland city like Spokane will colonize damp duct liner in Shoreline within a winter. The problem is not seasonal here. It is structural.

One more factor is the current wave of renovations. With the Lynnwood Link light rail stations at 145th and 185th opening in 2024, pre-sale flips and remodels have swept through adjacent neighborhoods, and the construction dust from knocking out walls and replacing panels finds its way into exposed ducts. Much of that original duct wrap still contains asbestos. A duct inspection after any renovation that opened a wall or ceiling is not precautionary theater in Shoreline; it is a legitimate health and documentation issue, and a post-renovation photo record is something we recommend for every flip we walk into.

Our Main Shoreline Services

Two services account for most of the calls we take from Shoreline homeowners, and each one has its own page with full local details.

Air Duct Cleaning in Shoreline

The homes here were built before air filtration was a design consideration, and the original duct runs have rarely been opened since they were installed. Our Air Duct Cleaning in Shoreline service starts with a camera inspection inside every run, then a negative-pressure extraction with Rotobrush or Nikro tools that removes what the camera shows. You get before and after photos of the inside of every duct run, plus a written price before we begin. No per-vent add-ons, no surprise line items.

HVAC Cleaning in Shoreline

When a Shoreline forced-air system has been pushing air through 50-year-old ductwork, the blower motor, coils, and plenum carry the same accumulated debris the ducts do. Our HVAC Cleaning in Shoreline service cleans the entire air pathway, including the return side, the supply trunk, and the equipment itself. The job concludes with the same documented photo record, so you can see what was actually removed from inside the system, not just trust a verbal summary.

Dryer Vent Cleaning in Shoreline

Shoreline’s ranch and split-level homes often route dryer vents through unheated crawl spaces, which means the warm, lint-laden exhaust hits cold metal surfaces before it reaches the roof or soffit cap. That temperature drop causes moisture to condense inside the pipe, and the condensation glues lint into a layer that narrows the vent opening over a single winter season. We do not run coupon specials or per-vent add-ons. We inspect, clean, and document the entire vent run, and you see the before and after photos from inside the pipe.

Dryer Vent Inspection

Signs you need it

Clothes are taking longer than 45 minutes to dry, or the exterior vent hood does not open while the dryer is running.

What it costs in Shoreline

A dryer vent inspection in Shoreline typically falls between $95 and $155, depending on vent length and access.

How we do it

We run a camera through the entire vent run from the dryer connection to the outside cap, photograph every restriction, and give you a written scope with the price for any needed cleaning or repair.

Vent Cleaning

Signs you need it

You can see lint escaping from the exterior cap, or the laundry room stays humid even an hour after a cycle finishes.

What it costs in Shoreline

Standard vent cleaning for a typical Shoreline ranch home runs $165 to $285, with longer or multi-story runs quoted higher.

How we do it

We use a negative-pressure extraction system with a rotating brush matched to the vent diameter, working from both ends of the run and photographing the inside before and after.

Lint Removal

Signs you need it

There is a visible mat of lint built up inside the outside vent opening, or the dryer’s lint trap is no longer catching the volume it used to.

What it costs in Shoreline

Heavy lint removal, where the vent is substantially blocked, runs $195 to $350 in Shoreline because of the extra passes and block-clearing work involved.

How we do it

We break up the compressed lint with specialized tools, extract it under negative pressure, and then run the camera again to confirm the full diameter is clear end to end.

Bird Guard Installation

Signs you need it

Birds are landing on or nesting at the exterior vent cap, or you hear scratching sounds near the laundry wall in early morning.

What it costs in Shoreline

A bird guard with installation ranges from $85 to $140, depending on the cap style and roof access.

How we do it

We install a stainless steel hood cover with a removable guard that blocks entry while maintaining full airflow, and we photograph the finished installation.

What Dryer Vent Cleaning Costs in Shoreline

How do I know if my Shoreline dryer vent is clogged?

Clothes take longer than one full cycle to dry, the laundry room gets humid, and the exterior vent cap stays closed while the dryer runs. In Shoreline’s unheated crawl spaces, condensation inside the vent makes lint stickier and more likely to accumulate. Call (806) 606-6902 for an inspection with a written price.

Why does Shoreline humidity affect dryer vents?

The marine air keeps lint damp, and the uninsulated vent runs through cold crawl spaces cause exhaust moisture to condense before it reaches the outside cap. That water vapor saturates lint inside the pipe, creating a thick, clinging layer that restricts airflow and resists simple dislodging. A yearly cleaning is not excessive in this climate.

Duct Repair & Sealing in Shoreline

In a 1960s Shoreline ranch, the ductwork is frequently held together with failed duct tape strips and pieces of sheet metal that vibrate apart every time the furnace kicks on. The unsealed gaps and disconnected joints pull crawl-space air directly into the system, and the same high humidity that condenses on the outside of the ducts also gets drawn inside through those openings. The result is air that has already been filtered and heated, leaking back out before it reaches the living space, while the system pulls in whatever is under the house. Our Duct Repair & Sealing service addresses these failures one run at a time, with a written price and a photo record of every repair.

Duct Sealing

Signs you need it

Rooms at the far end of the house stay cold in winter, and you can feel air movement near duct joints in the crawl space or basement.

What it costs in Shoreline

Whole-house duct sealing with mastic and metal tape typically runs $800 to $1,600 depending on the number of runs and access.

How we do it

We identify every leak with a smoke pencil and pressure testing, then seal all accessible joints with mastic and reinforced tape before rechecking airflow at each register.

Flex Duct Repair

Signs you need it

A flex duct has collapsed, kinked, or separated from its connection, usually in a crawl space or attic with tight clearance.

What it costs in Shoreline

Repairing or reconnecting a single flex duct run in Shoreline costs between $275 and $550, depending on length and access.

How we do it

We inspect the full run with a camera, identify the exact failure, cut and reconnect or replace the damaged section, and photograph the completed repair.

Mastic Sealant

Signs you need it

You see dust streaks or discoloration on the insulation around duct joints, indicating air escaping from the duct body.

What it costs in Shoreline

A mastic sealing pass for a typical Shoreline 3-bedroom home runs $700 to $1,400 for the full system.

How we do it

We brush mastic sealant onto every accessible connection, let it cure, and then re-pressurize the system to confirm the leakage rate dropped.

What Duct Repair & Sealing Costs in Shoreline

Why do Shoreline homes have so many duct leaks?

The forced-air retrofits from the 1970s and 1980s used duct tape that fails over time, and the original sheet metal runs were never sealed to today’s standards. Shoreline’s crawl-space moisture also corrodes the metal and loosens joints faster than in drier climates. A camera inspection will find them.

How much does it cost to fix leaky ducts in Shoreline?

Whole-house sealing typically starts around $800 and can reach $1,600 for a multi-story home with difficult access. We give a written price before any work starts, and that number does not change unless the scope changes and you approve it in writing. Call (806) 606-6902 for an exact figure.

Air Quality & Sanitizing in Shoreline

When crawl-space relative humidity stays above 80% through a Shoreline winter, the inside of every metal duct becomes a water-carrier for whatever spores are moving through the crawl space. The fiberglass liner in those old retrofit ducts absorbs moisture and holds it, creating exactly the environment where mold colonies establish themselves and then shed spores into the air stream every time the system cycles. Removing the visible dust is only part of the fix. The moisture-driven microbial growth that builds up in damp liner and around the evaporator coil needs a targeted response. Our Air Quality & Sanitizing service treats the full air pathway with the exact documentation we deliver on every other job.

Mold Treatment

Signs you need it

A steady musty or earthy odor comes from the registers when the system is running, especially in the first minute of a cycle.

What it costs in Shoreline

Targeted mold treatment for the plenum and primary trunk lines in Shoreline runs $350 to $850, depending on the extent of visible growth.

How we do it

We identify the affected surfaces with camera verification, apply an EPA-registered antimicrobial treatment, and return with a second camera pass to document the post-treatment condition.

Odor Removal

Signs you need it

Persistent odors from previous occupants, cooking, pets, or moisture remain in the house even after repeated cleaning of the living areas.

What it costs in Shoreline

Whole-system odor removal, including the duct surfaces and the air handler, runs $300 to $600 in an average Shoreline home.

How we do it

We identify the odor source with the camera, then apply a surface treatment to the duct interior and replace the filter media before retesting airflow at each register.

UV Light Installation

Signs you need it

Mold keeps returning around the evaporator coil despite previous cleaning, a common condition in Shoreline’s persistently damp crawl-space environments.

What it costs in Shoreline

UV light system installation runs $850 to $1,300, with the final price depending on the unit selected and the power access at the furnace.

How we do it

We mount the UV lamp directly above the coil, wire it to a dedicated circuit, and photograph the finished installation to show lamp placement and sealed housing.

What Air Quality & Sanitizing Costs in Shoreline

Is mold in Shoreline ducts actually dangerous?

Not all duct mold is toxic, but the spores released into living spaces can worsen allergies and asthma. Shoreline’s winter crawl-space humidity makes mold growth more persistent here than in drier parts of the state. The only way to know the full extent is a camera inspection of the duct interior, which is always included in our scope.

How does Shoreline humidity affect air quality inside ducts?

When crawl-space relative humidity exceeds 80% for months, moisture condenses on the cold metal of duct walls and saturates the fiberglass liner. That damp surface becomes a habitat for dust mites and mold. Without addressing the humidity or sanitizing the duct interior, cleaning alone will not fully stop the problem from returning. Call (806) 606-6902 for a written scope.
