Mold Removal Seattle

Mold Cleanup Seattle

Mold is a type of fungus, it is Nature’s Recycler, decomposing dead organic material

• Mold is a good thing… outside!

Mold needs TWO ingredients to initiate and propagate

• A constant water supply AND a food source
• Your wood dresser is a food source, but no water so no mold!
• Your kitchen sink is always wet, but it is not organic, so no mold!

Estimated over 100k species of mold worldwide; many colors 

• Penicillium, Aspergillus, Cladosporium, Chaetomium, Stachybotrys
• Only a handful are mycotoxins, toxic substances produced by a fungus

Mold is microscopic, always in the air, traveling as spores

• Spores are the reproductive method for all types of mold

Restoration companies are concerned about mold in three spaces

• Attic Space, Living Space, Crawlspace

Types of Mold

Know the Types: Mold Remediation Seattle Pros Tackle Every Day

Attic Mold

#1 Reason for Attic Mold – Greater than 90% of attic mold Seattle residents can face is caused by inadequate ventilation alone. Other common reasons include roof leaks around skylights and vents, tree branch damage during storms, or simply the age of your roofing materials. By identifying these issues early, Seattle homeowners can prevent costly mold growth and protect their property’s long-term health and value.”

• • Peaked roofs have more mold growth on north facing side – never gets warmed up in winter months due to Seattle latitude.

• We use chemistry developed by Sandia National Laboratories for military anti-germicidal warfare. Not available in stores, we work with a licensed formulator.

• Our process is efficient, effective, almost always only takes 1 visit, cost friendly.

Seattle Mold Cleanup Before & After

Living Space Mold

#1 Reason for mold – relative humidity sustained above 60%.

• Shower wall affected (organic), shower tile and shower head not affected (inorganic).
• Unoccupied home– hot water heater pinhole leak, hot moist air raises relative humidity.
• Inside a closet, only surface damage and can be cleaned and disinfected.
• Wood window seal – single pane glass, condensation, constant water supply, both mold ingredients. Best to have double-pane vinyl framed windows.
• Ceiling mold – if leak from above, material has to be removed and area disinfected.
• Inside Chemistry – quats, or essential oil Thymol (doesn’t even have a warning label, can drink it).

Crawlspace Mold

#1 Reason for Mold – Leak in the crawlspace from pressurized pipes (freshwater lines).

• Flooded or heavily water affected crawlspaces often have heavy wet, slimy mold on the joists and flooring ceiling.
• We first remove the batt insulation, then chemically treat the wood, then fog the area, then set drying equipment.
• If the area is not water affected but has surface mold because of higher RH (common in large areas), we remove the insulation, surface treat the wood, replace the same insulation.

Other Common Causes for Mold Remediation Seattle Residents Miss

Roof Leaks

Roof leaks are a common cause of mold contamination in both residential and commercial properties. When water infiltrates through damaged shingles or flashing, it often seeps into dark, undisturbed spaces like attics, insulation, or wall cavities. These areas provide ideal conditions for mold growth. If undetected, this hidden moisture can lead to severe mold infestations that compromise indoor air quality and weaken building materials. Immediate mold cleanup Seattle and professional inspection are necessary to stop further damage. Our team specializes in fast, effective mold remediation in Seattle, Lynwood and Western WA to keep your property safe.

Weather-Related Incidents

Storms, flooding, and heavy rainfall frequently trigger water damage in Western Washington homes, particularly in basements and crawlspaces. After the water recedes, lingering moisture creates the perfect breeding ground for mold. Timely mold remediation Seattle is essential to stop mold growth before it spreads.

Excessive Humidity

Humidity levels above 60% can quickly lead to mold growth in vulnerable areas like bathrooms, laundry rooms, and poorly ventilated basements. In these environments, moisture doesn’t evaporate properly, allowing mold to take hold.

A Washington State Certified Mold Inspector is required to identify mold

• Contractors and home inspectors use the term “possible microbial growth”

No certification requirements for performing mold remediation in Washington State

• IICRC offers mold remediation certification, we are an IICRC certified company

Two principal test methods

• Air sampling is the most common – determines ambient mold levels vs. outside levels
• Tape lift (surface) identifies mold on a surface, but does not indicate indoor air quality
