"We hired Dave to inspect and assess the mold in our home. He is a great man to work with, has years of experience, and is full of knowledge. The inspection provided all the information we needed and I've even contacted him multiple times with somewhat-related follow-up questions. He is a great contact to know when it comes to this area of expertise and I would highly recommend him."

"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."

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

Mold Testing and Remediation questions, answered by experts

Toxic drywall has a sulfur smell, similar to rotten eggs or poop. It’s often a sign that the drywall mud is expired, there’s mold or mildew growth, or there’s a leak in your home. Drywall can also absorb moisture during storage, transportation, or installation, resulting in a distinct musty odor.

The cost for mold remediation typically ranges from $1,125 to $3,350, with a national average of around $2,400. The final price depends on various factors, including the location and square footage of the affected area, the type of mold, and local labor costs.

Additional factors that influence the total cost include:

  • Extent of Damage: The overall price can increase significantly if extensive repairs are needed after mold removal, such as replacing large sections of drywall. Removing mold from a small area of drywall might cost between $300 and $825, but full wall replacement is more expensive.

  • Health Risks: The cost is also justified by the health risks associated with toxic mold, which can cause respiratory distress, act as carcinogens, or even damage the nervous system.

  • Comprehensive Service: Remediation involves not only removing the mold but also addressing the moisture issues that caused it to prevent future growth.

  • Testing and Air Quality: The need for safety testing and measures to improve indoor air quality can also add to the cost.

For an accurate estimate, it is best to consult a mold removal specialist who can assess the specifics of your situation.

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.

Any unexplained smell in your house should be investigated. However, some home odors are "red flag" worrisome because they pose immediate health and safety risks. Odors should be taken seriously when accompanied by headaches, nausea, or lightheadedness. If you smell an egg-like aroma, this is probably natural gas. You should leave the home immediately, and  contact your gas company.  

Just because you find mold in your home does not mean you need to pursue professional remediation services. You can often clean small amounts of surface mold, such as in bathrooms or on windowsills, using household products. However, extensive mold growth, persistent odors, or mold caused by water damage require professional remediation. A good rule of thumb is to hire a pro when the mold is in an area larger than 10 square feet, poses health risks, or affects the structural integrity of your home.
