"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

Yes, a one-time water leak can cause mold. Depending on the conditions, mold can begin to grow within 12 to 48 hours. The risk increases with the severity of the leak, high humidity, and when water soaks into absorbent materials like drywall. To prevent mold growth, stop the leak immediately and ensure the area is dried completely; running a blower fan for 24 hours is recommended. If you do notice mold, it's best to call a mold removal specialist to address the situation.

While mold in the bathroom can appear black, it isn’t always the dangerous black mold strain Stachybotrys chartarum. This type of mold typically appears after a flood or a long-term leak. If you suspect black mold, you should get it tested by a local mold testing service to determine whether it’s safe to remove yourself.

Air purifiers are meant to kill airborne mold, along with pollen and dirt. Air purifiers are a good option if you have allergies and need a whole-home solution, whereas dehumidifiers are best for naturally damp areas (like a bathroom). Consider getting an indoor air quality test to determine if an air purifier is right for you.

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.

Mold inspections are worth it because they can catch troublesome mold problems early before they get out of hand. It's worth it to address mold problems as soon as possible because mold can be hazardous to your health and cause damage to your home and its belongings. Mold testing and inspections are the best way to know if you have a mold issue in your house.
