"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

You can find the smell of mold in your house in two ways: following your nose, and using common sense tactics like looking anywhere there’s water first. Mold cannot form in a completely dry environment, which is why you see mold much more often under kitchen sinks than on garage floors. If you have looked everywhere and still can’t find the source, hire a pro, because you may have mold in your walls.

In mild cases of mold growth, you can DIY mold remediation with a simple cleaning using safe and natural cleaning solutions like baking soda, hydrogen peroxide, vinegar, or lemon juice. However, if the mold is larger than 10 square feet or you suspect toxic black mold, you should not do mold remediation on your own. Instead, you should hire a professional mold removal company to handle the job.

Many caulk alternatives are safe for use in kitchens and food preparation areas, provided you apply them correctly and let them cure for the right amount of time. If you’re unsure about this step, call in a pro to do it for you. Silicone putty and caulk strips are often used around sinks and countertops due to their waterproof and flexible nature. Always choose products labeled as safe for kitchen use and follow the manufacturer's instructions for proper application and curing.

Professionals suggest through ventilation, source removal, or filtration systems.

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.
