Why Mold Concerns Are Common in Bothell Properties

Bothell sits along the Sammamish River and spans both King and Snohomish counties. Like much of the Puget Sound region, it experiences prolonged rainfall and seasonal humidity.

Common mold risk factors in Bothell include:

Newer Developments & Construction Moisture

Bothell has seen rapid growth over the past 20+ years. Homes framed during rainy seasons without adequate dry-out can develop hidden moisture issues.

Townhomes & Shared Wall Assemblies

Attached housing is common. Moisture migration between units can impact indoor air quality.

Crawlspace Humidity

Many homes feature crawlspaces that may experience:

Elevated humidity
Limited ventilation
Damp soil
Insufficient vapor barriers

Split-Level & Hillside Homes

Lower levels may experience foundation seepage or condensation if drainage is inadequate.

Remodeling Activity

Significant remodeling and infill construction can introduce moisture if building materials are not properly dried.

Mold concerns frequently arise during:

 Trustindex verifies that the original source of the review is Google. Very disappointed with how 5 micron left my walls and building agree inspection
Usually a company would take carpet up in the corner of the room they did it right in the middle 47 cuts and slashes
Gave them a chance to make repairs - they refused
Be careful when using them and always have someone who knows what they are doing onsite
Refused to fix any of it
Costing me thousands- they said the building was going to be completely renovated - reason for sloppy job but I never told them that

I had some concerns for mold in my office after gone through some water damage a year back, and I contacted 5 microns, and they came in the following day and ran all the necessary tests. A couple days later they emailed my results with the breakdown of everything I needed to know and how to take care of my concerns! Pascal was also very professional! Highly recommend!
