The young lady I spoke to on the phone was extremely kind and informative. Any question I had she could answer. She represents the company extremely well! We need more people like her.

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

5 microns was so easy to work with. Absolutely loved Carole! She was so through and educating, a true pleasure to work. I was happy to give them a call and request her to come back for mold clearance.

On time smart great explanations. These folks know their stuff. Kind and don't make you feel stupid. General inspector and real estate agent very impressed as well. Can't go wrong with these guys. Bit expensive but you get what you pay for here.

โญ๏ธโญ๏ธโญ๏ธโญ๏ธโญ๏ธ 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!

Pascal was very professional and attentive to our needs. He was also empathetic to our situation. He took quite a bit of time explaining things to us. The report is very detailed and professional too. Thanks 5 Microns

If your home feels humid, damp, or uncomfortable even when the temperature seems normal, there may be an underlying indoor air quality or moisture issue.

Many Seattle homes experience elevated humidity due to climate, ventilation limitations, or hidden moisture problems.

At 5 Microns Inc., we provide air quality and moisture-related testing to help identify the cause and determine whether conditions may lead to mold or other indoor air concerns.

What Causes a House to Feel Humid?

Excess indoor humidity can result from:

  • poor ventilation or air exchange
  • high outdoor humidity entering the home
  • moisture buildup from daily activities (cooking, showering)
  • HVAC system inefficiencies
  • hidden water intrusion or leaks

When moisture isnโ€™t properly controlled, it can accumulate indoors.

ย Signs of High Indoor Humidity

You may notice:

  • air feels damp or heavy
  • condensation on windows
  • musty or stale odors
  • discomfort even with air conditioning
  • increased allergy-like symptoms

Why Humidity Matters

High humidity can:

  • create conditions for mold growth
  • affect indoor air quality
  • contribute to odors and discomfort
  • impact building materials over time

Testing helps determine whether levels are elevated and contributing to other issues.

Common Issues We Identify

Through testing, we often find:

  • elevated humidity levels
  • poor ventilation
  • hidden moisture sources
  • mold growth or conditions that support it

When Should You Test?

Consider testing if:

  • your home consistently feels humid
  • condensation or musty smells are present
  • you suspect moisture or water intrusion
  • symptoms occur indoors

Our Testing Process

We evaluate both air quality and moisture conditions.

Testing may include:

  • humidity and environmental measurements
  • indoor air quality assessment
  • mold air sampling (if needed)
  • ventilation evaluation

 

โœ”ย Certified lab analysis (if applicable)

โœ”ย Clear reporting

โœ”ย Practical recommendations

Cost of Testing

Typical pricing:

  • IAQ testing: $300 โ€“ $900+
  • Additional testing depends on conditions

Why Choose 5 Microns Inc.

  • Independent testing (no remediation upselling)
  • Certified laboratory analysis
  • Fast turnaround
  • Experience with Seattle homes and moisture-related issues
