"Henry came to our house. He was very knowledgeable about mold and what to look for. He answered all my questions and was very helpful. Peter who called me with the results was very nice and answered my questions. He even called back the next day when he noticed that an email he sent me didn t go through. They gave me a lot of information to help me continue my search to get rid of my mold and poor air flow."

"For anyone looking for a reliable and honest company- I highly recommend Pacific Pure Maintenance. After having exposure to TOXIC mold in my home, I had Pacific Pure Maintenance quote the project for mold remediation. My insurance company however, had me go with another company that cut and removed the mold without doing any kind of treating to the air. Months later I was still ill and contacted Pacific Pure Maintenance and they were very knowledgeable and helpful. They removed the toxins /air spores that were continuing to make me sick. (Something that other companies did not do NOR recommend). At the time, I knew NOTHING about mold exposure and I was looking to the experts for advise and none of the other mold removal companies were as helpful as Pacific Pure Maintenance. I am forever grateful to this company for doing what other companies didnt and going above and beyond."

"Shane was my first contact (via phone) and was very knowledgeable and went above & beyond to answer all my questions. I tend to have pretty good discernment, and I immediately sensed I was dealing with an honest, straightforward company. Shane offered me an appointment 2 days later that s fast! Awesome when you re concerned about mold! Ray came to our house (a several hour drive to the Redding area!), and was prompt & called ahead to be courteous. Total genuine and nice guy (especially bc he s a dog lover ;) He wasn t rushed at all, answered all our questions (we had a lot), and actually said he likes & welcomes questions! After we received our report & invoice, I THOUGHT I was messaging my husband, lol, but I texted Shane: Thumbs up! They did thorough testing, & the price was still what was initially quoted! I highly recommend these guys!!"

Mold Testing and Remediation FAQs, answered by experts

In most cases, it is safe to return home after mold remediation is complete. You should follow your mold remediation technician’s recommendations, but most pros request that homeowners wait one day after the process is complete to move back in.

After returning home, be sure to carefully inspect the exposed areas for any remaining signs of mold spores. Contact the mold remediation company if you detect any lingering mold.

Many types of mold spores and fungi spores are constantly present in the air, but they need a friendly surface and moisture to grow. Should some of these spores land on paper or wood with significant moisture present—such as drywall with a paper cover that is soaking up water from a leak—mold or fungi could begin growing. Dampness from leaky pipes, condensation on windows, leaks in a roof, flooding in a basement, or high, prolonged humidity in a small area all can create the excess moisture that mold and fungi need to grow in your home.

Checking for mold yourself is crucial, as catching mold in the early stages is ideal. Mold can appear green, brown, black, blue, or yellow. It can smell musty and can feel like velvet, leather, or cotton. 

Most often, mold grows near water damage. It’s best to inspect these places for signs of mold growth:

  • Basement: Look in corners, windows, carpet, closets, and around appliances. 

  • Bathrooms: Check around sinks, ceilings, and around toilets. 

  • Kitchen: Inspect around the sink, behind the refrigerator, and behind trash can.

  • Attic: Look near the insulation and near intake and exhaust vents.

No. When dry, mold enters a dormant state. While “sleeping,” the mold won’t multiply, but when it encounters moisture again, it springs back to life, releasing spores. That's why it's crucial to not only control humidity but also actively eliminate mold to prevent its resurgence and further growth inside your home.

Yes, mold can build up in a dehumidifier if not properly emptied and clean. Clean it every few weeks by removing dirty water, scrubbing with a mild dish soap, and allowing it to fully dry before reassembling.
