Professional Mold Treatment Services in Spokane
Stop Mold at the Source
Our certified team uses proven treatments to eliminate mold, sanitize surfaces, and restore a clean, safe environment in your home.
Understanding Mold and Why It Spreads
Mold is a naturally occurring fungus that thrives in damp, poorly ventilated areas. In attics and crawlspaces, small leaks or trapped humidity can lead to hidden mold growth—especially within or around insulation. Left untreated, it spreads quickly and releases airborne spores that may cause allergic reactions or respiratory issues.
Our Approach to Mold Treatment
We begin with a detailed inspection to locate all signs of mold growth. Once the source of moisture is identified and addressed, our team applies a top-tier hospital grade solution for attic mold remediation, combining powerful antimicrobial action with safety and ease of use. Its EPA-registered formula effectively eliminates mold, mildew, and bacteria, making it ideal for treating attic spaces prone to moisture and poor ventilation.
Depending on the severity, we may also:
- Scrub visible growth from surfaces
- Use misting or fogging systems to reach hidden areas
- Apply encapsulating sealants to prevent regrowth
We treat every attic like a contamination zone—safely containing the space, using protective equipment, and preventing spores from entering your living space.
Why VitalOxide?
Vital Oxide's case rests on its active ingredient: stabilized chlorine dioxide (ClO₂), which works as an oxidizer rather than a bleaching or poisoning agent. That matters for attics in a few specific ways.
Why it fits attic work
Attic mold almost always lives on porous wood — OSB or plywood roof sheathing and the rafters/trusses. Mold hyphae grow into the wood fibers, not just on top, so a product needs to actually penetrate and kill at the root, and it needs to be safe to leave behind because you're not rinsing an attic. Chlorine dioxide is a small, soluble molecule that carries into porous material, and it can also break down the protective fungal biofilms that shield colonies from surface-only treatments. Because it oxidizes, it also handles the musty odor at the source instead of covering it. It's EPA registration #82972-1, so the mold and mildew claims on the label are ones the EPA actually reviewed — not marketing language.
The other half is the safety profile. It's free of VOCs and harmful residues, non-corrosive to treated articles and gentle enough to handle without causing skin irritation. That means no fumes migrating down into living space through can lights and attic hatches, no corrosion on HVAC equipment, ductwork, nail plates or electrical boxes up there, and the family and pets can be home during the job. For a homeowner, the honest comparison is "the same product hospitals use on patient rooms" versus "gallons of bleach sprayed above your bedroom ceiling."
Why a sprayer and full saturation of the sheathing
The label's mold direction is specific: apply until visibly wet, and keep it completely wet for 10 minutes before allowing it to air dry. That contact time is the whole game. Wiping or misting a 1,200 sq ft attic can't achieve it; a paint sprayer can. Concretely.
Even, complete coverage.
Mold on sheathing is rarely confined to the visible black patches — spores and early growth are typically across the whole cold side of the roof deck. A sprayer treats every square foot between the rafters, up into the ridge, down to the eaves and behind blocking, where a hand applicator can't reach.
Real penetration.
Saturating (not just dampening) pushes the solution into the wood grain where the hyphae actually are, and keeps the surface wet long enough to meet the labeled contact time.
Consistency and speed.
A sprayer meters the same volume everywhere, so you're not under-dosing the hard-to-reach areas and over-dosing the easy ones. It also lets you do the job in one visit without the crew spending hours on their knees on joists.
Residual benefit.
It inhibits and keeps mold and mildew from growing for up to 4 weeks on soft surfaces, so full coverage means that inhibiting effect is uniform across the deck while the moisture fix (ventilation, bath fan venting, air sealing) takes hold.
Products commonly used that homeowners should worry about
- Chlorine bleach (sodium hypochlorite). Still the most common attic "treatment" in the industry. The chlorine evaporates and mostly stays on the surface while the water component soaks into the wood — feeding the mold you didn't kill. It off-gasses chlorine into the house, corrodes nail plates, duct straps and HVAC components, degrades wood fibers, and if it ever contacts an ammonia-based cleaner it produces chloramine gas. The EPA and OSHA both discourage bleach for porous-material mold.
- Ammonia-based cleaners. Strong fumes, ineffective on porous wood, and a dangerous mixing hazard with bleach.
- Encapsulant paints and "mold-proof" coatings sprayed over untreated mold. Some companies paint over the sheathing white without killing or removing growth first. It looks great in the after photos, hides the problem from the next inspector, and traps moisture in the wood. Encapsulation only belongs after the mold is dead and the wood is clean and dry.
- Ozone generators and "shock" treatments. Ozone is a respiratory hazard, has poor documented effectiveness on established mold in wood, and the house has to be vacated. The EPA has said ozone at safe concentrations doesn't effectively remove mold.
- Quaternary ammonium ("quat") disinfectants and phenolic products used as fogs. Effective on hard surfaces but they leave residues, are respiratory and skin irritants, and many aren't labeled for the porous-wood mold use they're being applied to. Dry-fogging with unregistered or off-label chemistry is a recurring problem in the industry.
- Undiluted or heavy hydrogen peroxide (higher than household strength) sprayed in bulk — a strong oxidizer that can bleach and degrade wood and is a skin/eye hazard for the applicator.
