Black Mold Removal in Portland, OR

The reality is that many mold removal companies in Portland don’t actually remove the mold. They paint over it. They arrive with an airless sprayer and a bucket of paint, cover the affected area, and leave. It may look clean on the surface, but the mold is still alive underneath, and it will return.

We do it differently. At NW Environmental Solutions, we spray an organic-based treatment that kills mold on contact. The difference is visible immediately. Then we fog the entire area to eliminate the airborne spores that other methods leave behind.

The best part: We back every single job with a 2-year guarantee.

Not sure if what you’re looking at is actually black mold? We can find out. Call us to schedule a mold inspection and we’ll identify what you’re dealing with before any removal work begins.

If you need a serious long lasting fix I definitely recommend these guys.

“Very impressed with their mold removal! We had mold in our attic and they did a thorough job removing it. They also tested every room in the house for mold. Also helped replace old clogged vents. Because they also do roofing they helped fix a mistake made by whomever installed the last air duct system who nailed straight thru the roof and was causing a leak, they patched that up.”

The Problem with Painting Over Mold

Here’s what typically happens when mold is painted over instead of properly removed:

  • The mold remains alive under the paint and continues to grow.

  • When proper treatment is eventually needed, the chemicals can’t penetrate the paint layer. The job becomes more difficult and more costly.

  • Within months, the mold pushes through the paint and comes back, often worse than before.

  • The homeowner ends up paying twice: once for the paint job that didn’t work, and again for proper removal.

This approach is called encapsulation, and it’s a shortcut that doesn’t hold up. We’ve been called to dozens of Portland homes to properly remediate mold after encapsulation failed.

How We Remove Black Mold

Our process is the same on every job, and there’s a reason for each step:

Fix the ventilation and ductwork first

Before we touch the mold, we deal with what caused it. That usually means replacing damaged ducts and reconnecting bathroom exhaust fans so they vent outside instead of dumping moisture into your attic. Without addressing this, mold will return regardless of how thorough the surface treatment is.

Spray the organic-based mold treatment. 

We apply an organic-based chemical directly to the affected surfaces. It kills mold on contact, and the results are visible immediately. No paint. No cover-up.

Fog the entire area.

This is the step most companies skip. When mold is treated on surfaces, spores are released into the air. If those airborne spores aren’t addressed, they settle and the problem begins again. Our fogging treatment fills the entire space. The fog reaches into crevices, behind insulation, and throughout areas the spray can’t access, eliminating remaining airborne spores.

About our fogging process

Fogging is included as a standard part of every remediation job we perform. It’s not an add-on or an upgrade. It’s built into our process because without it, airborne spores remain in the space.

Most companies in the Portland area don’t include fogging in their process. We do, because we’ve seen firsthand what happens when it’s skipped. Our goal is to get it right the first time so we don’t need to come back.

How Long Does It Take?

Most black mold removal jobs take 3 to 6 hours. It depends on how big the affected area is and how severe the growth. But in almost every case, you’ll see the results before we leave your house.

Questions About Black Mold Removal?

  • It can be. Black mold (Stachybotrys) produces mycotoxins that can cause respiratory issues, headaches, allergic reactions, and more serious health concerns with prolonged exposure. If it’s present in your home, it’s important to address it promptly.

  • Two things set us apart: we never encapsulate, and we fog every job. The spray treatment kills mold on the surface. The fogging eliminates what’s in the air. Most companies do one or the other, or skip straight to paint. We do both, every time.

  • Most jobs take 3 to 6 hours. You’ll see the difference before we leave your property.

  • Every mold remediation job we complete comes with a 2-year guarantee.

  • It depends on the scope. If you can already see the mold, give us a call and we’ll come out for a free estimate. If you’re not sure whether you have mold, start with a mold inspection.
