 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!

Why Mold Concerns Are Common in Maple Valley Properties

Located southeast of Renton, Maple Valley experiences prolonged rainfall, forested surroundings, and ongoing residential development.

Common mold risk factors include:

Newer Construction Moisture

Many Maple Valley homes were built in the past 20–25 years. Construction during wet seasons without adequate dry-out can contribute to hidden mold conditions.

Crawlspace Humidity

Homes with crawlspaces may experience:

Damp soil
Inadequate vapor barriers
Limited ventilation
Elevated humidity

Attic Condensation

Modern homes with tight building envelopes may develop:

Condensation on roof sheathing
Improper bathroom exhaust venting
Limited airflow

Forested & Shaded Lots

Dense tree coverage can reduce sunlight exposure and slow exterior drying, contributing to moisture retention.
