I called Steven V who came highly recommended by a roofer we spoke with. We wanted to assess the state of our attic space and kept getting highly contentious information from various folks we were calling out for consultations. In short, I think you can trust these guys. Steve was very thorough and forthright about the inspection/consult and showed me in detail the issues I was concerned with, and then some. He didn't try at all to upsell anything, and instead presented the information in a way that helped me make an informed decision. His experience was very apparent. I actually made several comments he could have easily turned into an upsell, and he recommended against them, showing total honesty.

If ever there were a Godsend of informed experience, Peter of Mold Solutions NW fits the bill to a tee. His crew performed an excellent job of remediation. And we appreciated his informative education. So I say thank you, Peter, for a job well done and your generous sharing of your knowledge!

I had a very last minute request that required the team to come out on the same day, for a very small project so I can close my house. Peter made special arrangement to have his team come out within 3 hours and took care of the issue with phone communications and pictures taken along the way so I can present them to my buyer. Their flexibility and professionalism are very much appreciated and will definitely use them again for any mold related jobs.

We had a mold issue show up on an inspection report. The client was very concerned. John from Mold Solutions NW showed up on time. His customer service was excellent. He took the time to explain the issue with the client and was able to put her mind at ease. I highly recommend calling Mold Solutions NW.

Mold Remediation

Mold is a sneaky predator that can grow virtually anywhere, and remain undetected for years. Our proven mold remediation solutions can provide you with the peace of mind you need to know that your home or workplace is free of mold—today, and for years to come

Mold Prevention

We can help you treat existing mold growth or better yet, prevent mold right from the beginning stages of construction of your new home! Protect your family and your new home against mold with our safe and effective Mold Prevention System.

Mold Inspection

Mold inspection involves identifying mold and what has caused mold to grow. Mold requires elevated moisture levels and this is something we focus on so that we can eliminate the cause or advise the homeowner what steps need to be taken to eliminate it.

Why the Cheapest-Sounding Bid Isn't Always the Best One

Most Seattle homeowners calling a mold removal company for the first time assume every estimate will look roughly the same. It doesn't. Some companies quote based on the whole room instead of the actual contamination. We inspect first and scope the job to what's really there.

Testimonial from a Seattle Home Owner

"Peter provided an assessment on some minor mold we had in the attic. While other companies dialed up the fear and quoted $3,000 for remediation, Peter actually recommended doing nothing as the mold wasn't active and growing."

Preventing Mold Before It Starts

Most mold problems come down to one thing: moisture that hangs around too long. A few habits go a long way toward keeping your home mold-free between inspections:

  • Run exhaust fans in bathrooms, the kitchen, and the laundry room every time they’re in use.
  • Repair plumbing leaks as soon as you spot them — don’t wait for a bigger problem.
  • Keep large furniture a few inches off the walls so air can circulate behind it.
  • Dry out any flooding or spills completely within 24-48 hours, even minor ones.
  • Watch for condensation buildup around windows, especially in winter.
