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.

We’ve been serving Alderwood Manor since Morton’s Air Duct Cleaning joined the Cedarwell family in 2005, and our technicians understand what the local canopy and climate do to ductwork here. This isn’t a cleared suburban neighborhood. The dense red alder and Douglas fir that give Alderwood Manor its name drop fine organic debris year-round, and the Puget Sound marine climate keeps humidity above 70% for months. That combination packs return-air intakes and breeds mold inside duct interiors that homeowners never see until the smell becomes unmistakable.
Why Morton’s Air Duct Cleaning Is Alderwood Manor’s Preferred Air Duct Cleaning Company
Alderwood Manor homeowners call us back because we treat their houses like the homes they are. Our background-checked, uniformed technicians arrive with shoe covers and drop cloths already on, and we work to the Cedarwell C.A.R.E. values, which means quiet tool settings during nap hours and pet-safe product choices where available. Paul Adeyemi built Morton’s on the principle that families deserve to know exactly what will happen and exactly what it will cost before anyone touches anything.
Our 365-Day Done Right Promise isn’t a slogan we mention when asked. It’s stamped on every job sheet. If something isn’t right, we make it right. Full stop. That matters in Alderwood Manor, where the original galvanized duct systems in most homes are now 50-70 years old and the 1980s flex-duct retrofits have their own failure patterns. You need a crew that will camera-inspect the sagging low points and show you what they found, not just vacuum and leave.
Every completed job includes a photo of the clean-up before our crew leaves, so you have visual proof your floors, furniture, and pet areas were protected and restored. A live person answers our phone 24/7, not a voicemail tree or chatbot. And we provide a written price before any work starts, every single time, with no exceptions.
Vent Cleaning in Alderwood Manor
Vent Cleaning in Alderwood Manor means more than wiping register covers. The north- and west-facing low-clearance crawlspace vents common to 1950s-70s ranch and split-level homes here sit almost flush with heavy alder leaf drop, so decomposed organic matter mats the exterior openings and creates a direct infiltration path into supply and return ducts. Our crews regularly pull leaf litter, black mold, and fine particulates from blower motors and vent lines that cleared suburban neighborhoods simply don’t face. A typical vent cleaning project in Alderwood Manor runs $180-$320 depending on system size and accessibility.
Exterior Vent Debris Removal
We start at the source. Our technicians clear matted leaf litter and organic debris from exterior intake and exhaust vents, then seal gaps where new infiltration would occur. This step alone often improves airflow measurably before we even enter the duct system.
Interior Line Agitation and Extraction
Using Rotobrush agitation tools and Nikro HEPA-filtered negative air machines, we dislodge packed debris from interior vent runs and extract it completely. We camera-verify the results so you see the difference, not just take our word for it.
Air Duct Repair in Alderwood Manor
Air Duct Repair in Alderwood Manor addresses the structural failures that cleaning alone cannot fix. The original galvanized sheet-metal duct systems in most local homes have reached 50-70 years of service, and rust at seams and joints is nearly universal. Meanwhile, the flex-duct retrofits added during 1980s-90s updates frequently sag into low points that trap standing moisture and debris through the October-April wet season. Repair becomes necessary when you feel weak airflow from certain rooms, smell mustiness that returns within weeks of cleaning, or see visible rust staining around register openings. Typical air duct repair in Alderwood Manor ranges from $280 for localized seam sealing to $1,200+ for extensive flex-duct replacement in crawlspaces.
Galvanized Duct Seam Restoration
We cut out rusted sections of original sheet metal and install properly sealed replacement segments, then test for static pressure balance. This preserves the durability of the original system while eliminating the air leaks that pull in crawlspace moisture and debris.
Flex-Duct Sag and Moisture Correction
Our crews re-support sagging flex-duct runs with proper hangers, replace water-damaged sections, and verify drainage paths stay clear. In Alderwood Manor’s damp climate, this prevents the standing moisture that breeds mold colonies inside duct walls.
Trusted Brands We Service in Alderwood Manor
We maintain equipment and stock replacement parts from Aprilaire, Abatement Technologies, Guardsman, and Rotobrush to keep turnaround fast for Alderwood Manor homeowners. When your Honeywell media air cleaner needs a new filter frame, or your Aprilaire humidifier pad is clogged with alder pollen scale, we don’t need to order and wait. Our vans carry the common components for systems installed in 1960s-1990s Alderwood Manor homes, and what we don’t have on hand, our Seattle office sources within a day. That matters when you’re running wood heat through a damp January and can’t afford a week without proper filtration.
Common Air Duct Cleaning Problems We See in Alderwood Manor Homes
- Blower motor caked with alder leaf litter. On a 1960s split-level off 36th Ave W in Alderwood Manor, our tech pulled the air handler cover and found the blower motor caked with alder leaf litter and black mold that had been drawn through the low north-facing crawlspace vents. We set up negative pressure with HEPA filtration, ran agitation tools through the 50-year-old galvanized supply and return ducts, and camera-inspected the sagging 1980s flex-duct low points where standing moisture had pooled. After source removal, the homeowner said the musty smell that had lingered every wet season was finally gone.
- Original galvanized ducts rusting through at seams. The 1950s-70s sheet metal in Alderwood Manor’s ranch homes corrodes from the inside out where condensation meets organic acids in trapped debris, creating pinhole leaks that pressurize crawlspaces and draw in more contaminants.
- Flex-duct retrofits sagging into standing water. The 1980s-90s flexible duct additions commonly found in local split-levels droop between supports, forming low points where the 35-38 inches of annual Alderwood Manor rainfall translates to chronic crawlspace dampness and mold growth.
- Rural outbuilding systems overloaded with dust and lint. Properties on unpaved roads with wood heat and shop or barn duct runs see MERV-rated filtration overload quickly, and longer service drives mean these systems often get deferred until airflow is severely compromised.

FAQs About Air Duct Cleaning in Alderwood Manor
Every 2-3 years for most Alderwood Manor properties with these conditions, compared to the 3-5 year interval typical of cleared suburban neighborhoods. Wood heat produces fine ash particulates that bypass standard filtration, and unpaved road dust loads MERV filters faster than pavement-served homes. If you run a shop or barn with ducted heat, those outbuilding systems often need annual attention. Call (323) 918-4345 and we’ll assess your specific setup.
The prevailing wind patterns in the Puget Sound lowlands drive alder and fir debris directly against north- and west-facing building exposures, and the low-clearance vents common to 1950s-70s slab-adjacent foundations sit almost flush with the leaf drop zone. Cleared neighborhoods with raised foundations and larger vent clearances don’t experience this structural infiltration path. We address it by clearing exterior vents thoroughly and sealing gaps where new debris would enter.
Often yes. The 50-70 year old galvanized sheet-metal systems in most Alderwood Manor homes show rust at seams and joints that cleaning cannot reverse. If you feel weak airflow in certain rooms or smell mustiness returning within weeks of service, the ducts likely need seam sealing or section replacement. We camera-inspect before quoting so you know exactly what you’re facing.
Relative humidity stays above 70% for much of the October-April wet season here, and that sustained moisture allows mold colonies to establish inside duct interiors even in well-maintained homes. The 35-38 inches of annual precipitation keeps crawlspaces chronically damp, and when combined with organic debris from the alder canopy, you have the exact conditions mold needs. Routine cleaning becomes mold mitigation, not just maintenance.
Yes. We schedule these jobs with realistic drive-time buffers and bring extra filtration capacity for the heavier dust loading typical of shop and barn duct runs. The same written price guarantee, shoe covers, and photo documentation applies. Call (323) 918-4345 to discuss your property’s layout and we’ll build a scope that covers every system you need addressed.
