Colin Merritt has led Bellows since its founding, and our Air Quality & Sanitizing in Des Moines crews understand the local failure patterns that out-of-town operators miss.

Our Air Quality & Sanitizing Services in Des Moines

Mold Treatment

Mold treatment in Des Moines homes typically costs $320-$580 depending on duct length and contamination severity. In Des Moines’s hillside neighborhoods west of Pacific Highway S, salt-laden marine air infiltrates crawl spaces from the Puget Sound bluffs, creating a biological growth pattern inside duct liners that is rare even a few miles east toward the I-5 corridor. Original fibrous duct board in 1960s homes absorbs moisture from damp crawl spaces, fostering mold that recontaminates cleaned ducts within weeks if not sealed. We treat with EPA-registered products, then seal penetrations to block future intrusion. We recently treated a 1960s split-level on Marine View Drive where original flex duct in the vented crawl space was coated with black mold from decades of salt-moisture exposure. After thorough Rotobrush cleaning and UV light installation, we sealed all crawl space penetrations to block future marine air intrusion.

Bacteria Sanitizing

Bacteria sanitizing runs $280-$450 for most Des Moines homes, applied after mechanical cleaning to eliminate what brushing alone cannot reach. Vented crawl spaces on hillside lots rarely fully dry between storm seasons, allowing persistent humidity that sustains biological growth even after cleaning. We use professional-grade applicators from Abatement Technologies to distribute sanitizer throughout the system, including the dead legs and returns that harbor the most buildup. The 98198 zip code sees more of this persistent dampness than inland Kent or Federal Way, and our protocol accounts for it.

Odor Removal

Odor removal service in Des Moines ranges from $180 for light treatment to $420 for deep contamination requiring multiple applications. How does the marine air smell affect indoor air quality in Des Moines homes? That persistent musty, brackish odor many homeowners notice in spring and fall comes from salt-laden marine air accelerating corrosion on metal duct components and degrading flexible duct liners faster than in inland suburbs. The smell isn’t just unpleasant; it signals active biological processes that affect respiratory health. We source the contamination, eliminate it mechanically and chemically, then verify with camera inspection that the source is gone, not masked.

UV Light Installation

UV light installation in Des Moines costs $380-$720 per unit depending on system size and placement complexity. Can UV lights really prevent mold regrowth in my Des Moines crawl space ducts? Yes, when properly specified and positioned - but only after thorough cleaning and sealing of crawl space penetrations. We install Honeywell and Aprilaire UV-C units at the coil and supply plenum, the two critical growth points in marine-climate systems. The light interrupts mold spore reproduction, which is essential in Des Moines where ambient humidity never drops low enough to inhibit growth naturally. Without sealing the crawl space first, though, UV is a partial solution at best.

Trusted Brands We Service in Des Moines

We stock and install professional-grade equipment from Rotobrush, Nikro, Abatement Technologies, Honeywell, and Aprilaire - the same brands serious HVAC contractors specify for Pacific Northwest marine climates. For Des Moines homeowners, this means no waiting on special orders when your 1970s ranch needs immediate attention. Our trucks carry UV-C units, HEPA filtration media, and EPA-registered sanitizers sized for the duct profiles common in mid-century Des Moines homes. When we quote a job, the parts are already on the truck or available from our Seattle warehouse within hours, not days.

Common Air Quality & Sanitizing Problems We See in Des Moines Homes

• Original fibrous duct board saturated with decades of marine moisture. The 1960s-70s ranch and split-level homes that dominate Des Moines’s residential core often still run original duct board through vented crawl spaces. That material acts like a sponge, and once mold colonizes the interior surface, simple cleaning cannot restore it. Replacement with sealed metal or modern flex becomes the only lasting fix.
• Salt corrosion on metal components invisible from the living space. Salt-laden marine air from Puget Sound accelerates corrosion on metal duct components and degrades flexible duct liners faster than in inland suburbs. We find rusted collar ties, corroded dampers, and degraded flex connections that release particles into the airflow. Camera inspection reveals what homeowners cannot see from the register.
• Persistent humidity sustaining biological growth between “clean” cycles. Vented crawl spaces on hillside lots rarely fully dry between storm seasons, allowing persistent humidity that sustains biological growth even after cleaning. Without addressing the moisture source through sealing and dehumidification, mold returns within one to two seasons.
• Odors misattributed to plumbing or general dampness. Many Des Moines homeowners spend months chasing a musty smell they assume comes from a drain or foundation leak. The actual source is often contaminated ductwork distributing spores and volatile organic compounds every time the furnace or AC cycles. Proper duct inspection isolates the real problem.
