"Had this machine put in to kill mold with a guarantee to come back if the mold come back . Well guess what it came back . They came out and said that the warranty was void because the machine was unplugged . Once i informed them we had cameras they made another excuse . That was another lie . Then when i addressed the situation the owner then yelled at me accused me of threatening him so he could justify not covering the warranty.

HouseMaster has been in the home and business inspection industry for more than 3 decades, inspecting over 2 million homes across the United States. We are one of the most trusted names in home inspections, providing our customers with the highest quality.

"The team did an excellent job. Two walls were removed and they cleaned and treated inside the walls. They also pulled up my carpet which was a great help, as I was worried about spores being in there after the work. They sealed off each area with plastic to contain it and used the appropriate safety equipment. It is difficult to find mold specialists who really know what they are doing. They were transparent and informative about the job, which made me feel confident moving forward with them. The work performed was very thorough and they kept me updated throughout the process with pictures. Everyone I met/talked to from Stay Dry was very professional and polite. It is apparent that they care about the quality of their work and their customer service. That matters to me because I need to feel safe and healthy in my home. I will hire them for the next job."

Mold Testing and Remediation questions, answered by experts

A mold inspection costs $660 for the average homeowner. This cost can range anywhere from $150 to $2.800, depending on the size of your home, the number and type of samples, and the number of hard-to-reach areas of your home that need testing. 

Places like air ducts, crawl spaces, and wall cavities are particularly inviting for mold spores but require more time from your mold inspection pro. Additionally, swab testing, where a surface sample from an area of your home is collected, generally costs $200 to $300 per area. Air testing, however, is more costly, ranging from $250 to $350, but can cost as much as $700.

Mold grows in areas with humidity levels above 60%, but ideal conditions for mold growth occur when humidity is between 70% and 90%, especially in poorly ventilated areas. To prevent mold growth, aim to maintain indoor humidity levels between 30% and 50% using dehumidifiers, proper ventilation, and temperature control. Regularly check your home's humidity with a hygrometer to help you monitor and avoid conditions conducive to mold.

Standard wood stains often contain volatile organic compounds (VOCs), which the EPA states can irritate those exposed to their odor. Inhaling the fumes can pose health risks to humans. Prolonged exposure to VOCs from wood stains can lead to wood stain poisoning, manifesting in symptoms such as a burning sensation, blurred vision, and even collapse. Taking precautions when using these products is crucial to minimize the risk of adverse health effects.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

If you’ve spotted a skunk or know that one of these furry creatures sprayed one of your family members, your answer is fairly obvious. However, a skunky smell in your house that isn’t coming from these critters may be a sign of a dangerous gas leak. If you suspect this, leave your home immediately and call emergency services. It could also be a build-up of dangerous gas in your home’s septic system or plumbing. Call a professional plumber near you to make an assessment.
