"The owner, Donald, is a good communicator. He arrives on the job on time and worked over several days until the project was done. He was meticulous and thorough. My wife and I felt that what we paid for the project was reasonable and appropriate. Donald was very personable and easy to work with. We'd hire him again, and recommend him to you. Tim Fox, former Montana Attorney General."

"Mike helped me move out of my 4000sq/ft house. It was a big day of lifting carrying and stacking objects and he was capable and up for the challenge. Fun guy to spend a day with and went beyond the expectation, all for a fraction of the cost of the other quotes I received. Would recommend if you need a few extra hands for a move."

Biohazard Remediation FAQs, answered by experts

After you clean mildew or mold that appears in your home, you expect the nasty odor to disappear, too. Sometimes, though, the odor can linger after cleaning. To get rid of a mold smell, you may need to clean the area every few days for a few weeks. Use a dehumidifier or fans to try to remove moisture from the area. If the odor remains after a few weeks, you may still have mold or mildew in the area. Call a mold testing professional for another inspection.

Yes, it is common for mold to grow on the underside of the siding due to the moist atmosphere. When there is an abundance of moisture, mold has the ideal environment to spread and thrive. This fungus can be found on virtually any surface, both indoors and outdoors. Generally, it is most active when the environment is warm, damp, and humid.

The safest way to neutralize bleach for disposal is to mix one teaspoon of sodium metabisulfite (also called disodium disulfite, pyrosulfurous acid, and disodium salt) with 2 1/2 gallons of water. Then mix 1 gallon of this solution per 1/3 cup of bleach. But you still must handle and dispose of the mixture carefully.

Powdery mildew is exactly like it sounds—a widespread mold that looks like baking soda or talcum powder. It’s usually seen on plants and spread in warm climates, which is why many people first discover this issue in their home greenhouse. Over time, plants have become resistant, but if you see it spreading, baking soda and water can eliminate many cases. Otherwise, consider neem oil or fungicide. 

Dehumidifiers do not directly remove mold or spores from the air. However, by lowering the room’s humidity, spores are less likely to flourish when landing on surfaces.
