"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

Mold Testing and Remediation questions, answered by experts

It is safe to remove old linoleum, but it may require the help of a specialist due to the risk of asbestos in the material. Before you cut into linoleum or try to peel it up, have it tested for asbestos. If it tests positive, professionals will need to remove it to prevent the risk of health issues from airborne toxic particles. If it’s asbestos-free, DIY removal is possible and safe.

A one-time leak can cause mold, but it depends on the severity of the leak, the humidity in your home, and other factors. If you catch the leak quickly and the damage is minor, you may not experience any mold. If the water soaks into absorbent materials like drywall and doesn’t dry quickly enough, though, mold will start to grow within 24 to 48 hours. If your home’s interior has a high humidity level, mold could set in within just 12 hours. It’s best to run a blower fan for 24 hours after a one-time leak to avoid mold growth.

Mold loves moisture, so prolonged high humidity levels or standing water can trigger mold growth. Mold also needs a food source to grow on, such as wood, fabric or another material. However, it's moisture that's most important for mold growth, which is why you want to keep humidity levels low.

You probably have mold on your shower curtains because mold and mildew thrive and spread in warm, dark, wet, and unventilated spaces. Your shower is the perfect environment, especially the shower curtains, because they trap water in the folds and creases, plus they’re exposed to the most water spray. The best way to ensure mold stays off your shower curtains is to keep it dry so it doesn’t have a place to grow. Doing this can also help keep mold off your bathroom ceiling.

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.
