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 Air Duct Cleaning Across Shoreline
Air duct cleaning in Shoreline, WA typically runs $350-$650 for a whole-house residential system, and every job starts with a written price before we touch anything. We’re Morton’s Air Duct Cleaning, and our crews know Shoreline’s neighborhoods from Richmond Beach to Ridgecrest to Briarcrest - the 1950s ranches with crawl-space ductwork, the split-levels off NE 145th, the homes that sat through years of light rail construction dust. Scheduling and dispatch run through our Seattle office, but the technicians who arrive at your door live and work in this market. They understand why a Shoreline home’s ducts are different from a newer build in Bothell or a dry-climate house east of the mountains. Call (323) 918-4345 and a live person will pick up, 24 hours a day.
Why Morton’s Air Duct Cleaning Is Shoreline’s Preferred Air Duct Cleaning Company
We’ve been part of the Cedarwell family since 2005, and our reputation in Shoreline is built on what happens inside the house, not what we claim on a website. Shoreline customers mention the same things in reviews: shoe covers at the door, drop cloths before the vacuum comes in, the written price that matches the final invoice, the photo of clean floors we send before we leave.
Our response time to Shoreline is same-day or next-day for most requests - we’re not crossing a bridge or fighting I-5 from the eastside. That matters when you’ve just had an inspection for a home sale and the buyer’s agent flagged the ductwork. We know the difference between a Richmond Beach home with salt air corrosion on the registers and a Ridgecrest split-level with original 1960s fiberglass ductboard in the crawl space. That local knowledge changes what we bring and what we look for.
Every technician is background-checked, uniformed, and trained to the Cedarwell C.A.R.E. values. We work to the Cedarwell Care Promise on every single visit: written price first, shoe covers and drop cloths always, quiet tools during nap hours, pet-safe product choices where available, and a photo of the clean-up before the crew leaves. Our Air Duct Cleaning team doesn’t rush. We’ve seen what rushed looks like in Shoreline crawl spaces - disconnected runs left dangling, boot gaps unsealed, concrete dust stirred around and called “cleaned.”
Air Duct Inspection in Shoreline
Air Duct Inspection in Shoreline starts with understanding that most of the problems in this city’s housing stock are invisible from the living room. We use camera-equipped scopes from Nikro and Abatement Technologies to trace every supply and return run, especially the originals sitting in damp crawl spaces beneath 1950s-1970s ranches and split-levels. A typical inspection in Shoreline runs $150-$250, and we apply that fee toward the cleaning if you proceed.
What We Look For Underground
Shoreline’s crawl-space foundations hold the real story. We check for crushed supply runs where someone crawled through for plumbing work, separated return joints that pull musty crawl-space air straight into bedrooms, and the gray-tan concrete particulate layer that sits in return plenums near the light rail station footprints. Camera inspection finds what a flashlight and mirror cannot.
Static Pressure and Flow Mapping
We measure static pressure at the air handler and temperature differential at each register. In Shoreline’s older homes, we often find back bedrooms running 8-12 degrees off the thermostat setpoint because of disconnected or blocked runs. The inspection report shows you exactly where the air is going, and where it isn’t.
Residential Air Duct Cleaning in Shoreline
Residential Air Duct Cleaning in Shoreline means source removal under negative pressure with HEPA filtration - not a brush shoved a few feet into each register boot. A typical whole-house residential cleaning in Shoreline runs $350-$650 depending on system size, accessibility, and whether we find separated runs that need reconnection and sealing. We give you that number in writing before we start.
Source Removal, Not Surface Dusting
Our Rotobrush and Nikro equipment agitates debris at the duct wall while a negative-pressure HEPA vacuum captures it at the source. In Shoreline homes, this matters enormously. Without negative pressure and HEPA containment, the fine silica and concrete fines from years of light rail construction get stirred into your living space instead of removed from it.
Sealing the Real Leaks
Cleaning without sealing is temporary in Shoreline. We reconnect separated return joints, seal boot gaps with mastic, and close penetrations where crawl-space humidity and ground dust re-enter the system. The 365-Day Done Right Promise covers this work - if the static pressure drops or the grit returns because we missed a gap, we make it right.
Trusted Brands We Service in Shoreline
We clean and service systems with components from Honeywell, Aprilaire, and Abatement Technologies - brands we trust because they hold up in Shoreline’s demanding conditions. Honeywell media air cleaners and Aprilaire whole-house dehumidifiers are common in local retrofits, and we stock replacement parts so Shoreline customers aren’t waiting on cross-country shipping. Our Nikro and Rotobrush cleaning equipment is professional-grade, not rental-store level, because Shoreline’s ductwork - original sheet metal in damp crawl spaces, loaded with construction-era particulate - demands it. When we find an Aprilaire or Honeywell component that needs attention during a clean, we can often address it same visit.
Common Air Duct Cleaning Problems We See in Shoreline Homes
- Crushed and disconnected supply runs in crawl spaces. Shoreline’s original 1950s-1970s ductwork sits low in damp crawl spaces where plumbing repairs, pest activity, or simple age have flattened or separated the metal. The back bedroom stays cold because the air never arrives, not because the furnace is failing.
- Concrete and silica particulate in return plenums near light rail stations. Homes within roughly a half-mile of the NE 145th St or NE 185th St station footprints routinely hold a gray-tan layer of fine grit - visually distinct from ordinary lint - drawn in during years of tunneling, grading, and station-box excavation from 2019 to 2024.
- Mold and dust-mite allergen buildup from marine humidity. Shoreline’s relative humidity sits above 80% for months each fall through spring. That moisture wicks into crawl-space ductwork and creates conditions for colonization that drier inland suburbs simply don’t face.
- Boot gaps and unsealed returns pulling crawl-space air. Original installations in Shoreline ranches often left register boots and return plenums unsealed at the floor or wall penetration. The system “cleans” the crawl space instead of the living space, and no filter change fixes that.
Pricing for Air Duct Cleaning in Shoreline, WA
A whole-house residential air duct cleaning in Shoreline typically runs $350-$650. Air duct inspection runs $150-$250, applied to the cleaning if you proceed. Dryer vent cleaning, often booked together, adds $120-$180. What moves the number: system size (a 2,000-square-foot ranch with full basement versus a split-level with cramped crawl space), accessibility, the amount of construction particulate we find, and whether we need to reconnect or seal separated runs.
We don’t quote per-vent. One flat price per system, agreed in writing before work starts. No teaser coupon that triples once the van is in your driveway. We serve Shoreline families who’ve been burned by that model before. Call (323) 918-4345 for a free estimate - we’ll ask about your home’s age, square footage, and any pressure or odor issues, then give you a real number you can plan around.
We Also Serve Cities Near Shoreline
Our crews work throughout the metro area, and we regularly schedule jobs in Seattle, Spokane, Tacoma, and Vancouver. Each city’s housing stock and conditions are different - what we find in a Spokane ranch on a dry basalt slope is not what we find in a Shoreline crawl space - and our inspections and pricing reflect that local reality.

FAQs About Air Duct Cleaning in Shoreline
It’s likely fine silica and concrete particulate from the Lynnwood Link light rail construction that bored through neighborhoods near NE 145th St and NE 185th St between roughly 2019 and 2024. That gray-tan grit is visually and texturally distinct from ordinary household dust, and it doesn’t respond to filter changes because it’s already inside the return plenum. We remove it with source-removal techniques under negative pressure and HEPA filtration, then seal the system so it doesn’t reaccumulate. Call (323) 918-4345 for an inspection - estimates are free.
Original sheet metal can almost always be cleaned and restored if the metal itself is intact. What we more often find in Shoreline ranches is crushed runs, separated joints, or boot gaps - problems that need reconnection and sealing, not replacement. Camera inspection tells us which. Replacement becomes necessary only when the metal has rusted through or the ductboard has degraded to structural failure. Call (323) 918-4345 and we’ll inspect before recommending anything.
Yes, the conditions are genuinely favorable for it. Shoreline’s relative humidity regularly exceeds 80% from October through April, and that moisture wicks into crawl-space ductwork where temperatures are cooler and condensation forms. We find active mold colonization and dust-mite allergen buildup more frequently here than in drier inland markets. Source removal with HEPA containment, followed by sealing gaps that pull humid crawl-space air, is the effective response - not chemical fogging that leaves residues. Call (323) 918-4345 for an inspection.
Source removal means we agitate debris at the duct wall and capture it under negative pressure with HEPA filtration at the point of origin - we don’t push it deeper or stir it into your living space. It matters more in older Shoreline homes because the construction-era particulate and decades of accumulation are finer and more abrasive than typical household dust. Without negative pressure containment, that material becomes airborne inside your home. Our Rotobrush and Nikro equipment is built for this. Call (323) 918-4345 for an exact quote.
Yes, and increasingly buyers and their inspectors expect it. A clean system with documented inspection, reconnected runs, and sealed joints removes a common negotiation point in Shoreline’s competitive mid-century market. We provide before-and-after photos, static pressure readings, and a written summary of work completed that you can share with listing agents and buyers. The investment typically runs $350-$650 and pays back in smoother transactions. Call (323) 918-4345 to schedule before your listing photos.
