"I called Montana Basement Solutions when we discovered mold in our basement. We were stressed and worried about the safety of our children in the home. When I called, the receptionist quickly put me in touch with Rich, who talked me through the process and helped give me information about what I could do prior to having someone come out. He set up a time when one of the guys would be close to town and waved the travel fee since he would be in this area anyway. He was kind, knowledgable and made me feel like he really wanted to help us. Wynn came out a few days later and gave us tons of information. He walked us through what we needed to do and was willing to spend an exorbitant amount of time, late into the evening, prior to a long drive home, explaining everything we needed to know about our problem. He addressed every one of our concerns and answered all of our questions in depth. He was friendly, knowledgable and professional. I would highly recommend this company. From the very first phone call, I have been so pleased with the customer service I have received. I had called 4 other companies prior to and after talking with Montana Basement Solutions, 2 who said they would come out two days later ( never heard from them) and 1 that still has not called back (and I have left 2 messages). I am so grateful for the time Wynn gave to us and did I mention , he did all of this free of charge? He also gave me the answer to my problem and it did not require me using their services. If you have a mold problem, I would start with Montana Basement Solutions."

Mold Testing and Remediation questions, answered by experts

Knowing what to expect during a mold inspection can help make the process easier. Prepare by closing doors and windows for 48 hours, turning off HVAC systems for at least two hours, and avoiding disinfectant chemicals for at least 48 hours. 

The mold inspection process takes between 24 and 48 hours. Your professional will check walls, fireplaces, air ducts, vents, and windows for visible spores. They will also take an outdoor base air sample. Your pro will send these samples to a lab for testing and advise you on the findings.

Signs you may need mold remediation include visible mold growth on walls or ceilings, a persistent musty odor, or health symptoms like allergies and respiratory issues. Areas affected by water damage or excessive humidity are prone to hidden mold. A professional inspection can confirm whether mold remediation is required, especially for large or concealed infestations.

Mildew is a type of mold that forms in areas of excessive moisture and poor ventilation. Although it commonly exists in household air, it can’t take hold and spread if a surface is clean and dry. Generally, if you have any mildew or mold issues, it’s because the humidity in either your house, room, cabinet, or cupboard is above 50 percent. Common areas where you’ll find mildew are around water sources, which is why it’s commonly found near showers and in kitchen sinks.

Mold growth is just one common sign of excess moisture in the bathroom. You may also see the paint in the room start to peel away from the walls, or that the walls remain wet for some time after you bathe.

Condensation on the windows is another sign that your bathroom has a potential moisture problem. The room itself may start to smell like mildew.

Condensation in your dryer can create a dangerous situation. It can cause lint to clog up the venting components of the system. If you have a gas-powered dryer, excessive lint buildup can create the potential for carbon dioxide buildup within your home. Clogged vent systems can also be a severe fire hazard.
