"Dave was extremely helpful in giving grounded, low cost solutions for my ongoing mold issue. Proving sound and reliable advice in a sea of so much overwhelming information was invaluable. He took the time to look over a previous report that provided misguided information and recommendations and took the time to walk me through the correct steps saving me so much time and headache. Thank you so so much. I highly recommend this company for their mold services and consult."

"They were the third mold company to work on my problem and the only one to get it right. Showed up quickly, worked hard to remove a shower and floors in upstairs bathroom and destroy mold throughout and also removed ceiling from dining room below and treat that area. Their knowledge was apparent, and I have great confidence in their expertise and work product, especially after a couple of disappointments with other mold "experts" prior to engaging Premier. Very high rating."

Mold Testing and Remediation questions, answered by experts

Pressure-treated wood offers some protection from the elements but doesn’t protect against mold. However, if you spot mold growing on pressure-treated wood, it doesn’t indicate rot or an interior fungal infection—the treatment process ensures that the mold stays on the exterior. Keep the wood dry, but if you spot some mold, remove it immediately and clean the area.

Yes, mold can grow under your shower tiles if they aren’t thoroughly waterproofed. Even if you have a durable, non-porous tile material, water can make its way through grout or gaps around the edges of the shower. This will slowly erode the grout, which can cause tiles to come loose. It can also trap moisture behind tiles, and within a day or two, mold and mildew can rapidly grow.

Mold can be hazardous to your health. Some people are allergic to mold and experience a reaction when exposed to mold spores. The reaction varies from person-to-person, but can include a runny nose, skin irritation, and asthma attack. Mold can also be irritating to people who aren't allergic, causing respiratory, skin, and eye irritation. In some cases, mold exposure can lead to infections.

Most of the health problems associated with exposure to fiberglass insulation are short-term in nature. You may suffer from minor and temporary skin or eye irritation if you come into contact with it, and you may experience some sneezing, coughing, or breathing issues if you inhale fiberglass. Those with asthma and allergies may suffer more and longer. Though fiberglass was once a suspected carcinogen, there’s now no good evidence that exposure to fiberglass can cause lung cancer.

Bathroom tiles can contain asbestos, just the same as patio tiles or kitchen tiles. Remember that asbestos was used primarily for its insulative and fire-resistant properties, both of which are desired in a house. Before we knew asbestos caused cancers and other diseases, it made a lot of sense to include it in many different building materials, including bathroom tiles.
