"Did you know mildew is the gas given off from mold?? Joe offered great advice about the growth of mildew into mold, and my landlord's responsibility to remove it. I feel that he is knowledgable and would perform a thorough inspection. Based on my present economics and quotes from 2 other firms, and not to discount Mold Testing CO at all, I decided on another company. Joe at Mold Testing CO is definitely my second choice."

"Working with Belmont was fantastic. They were fast to respond, came and did a free inspection of my mold situation, were super informative (be prepared to learn, if you d like, everything there is to know about the various forms of mold), were very courteous, shared space with another contractor to help me correct the water leak, worked around my hectic schedule, made a temporary containment zone, and provided an accurate quote. When we did finally have them come to mitigate, they were super diligent and honest. Final removal came under the estimate. Thanks for making my home safe for my newborn and family."

Mold Testing and Remediation FAQs, answered by experts

If you find black residue in your toilet tank, chances are it’s caused by manganese deposits from hard water and not mold growth. You can prevent these deposits from damaging your toilet by installing a water softener in your home, which also might improve the quality of your drinking water. You can also remove the deposits inside your toilet tank once every six months or so to prevent them from causing problems with toilet functionality.

Costs depend on property size, test types, and additional services like mold sampling.

If you can locate building records, you may be able simply to see what type of tiles (or bonding agent) was used. Any flooring made between 1950 and 1989 more than likely contains asbestos. Asbestos tiles can also be slightly thicker than other tiles and often measure 9” x 9”, 12” x 12”, and 18” x 18. Black mastic was a commonly used adhesive that contains asbestos.

Signs of mold under silicone caulk include discoloration or dark spots appearing through or around the caulk, a musty odor in the area, and visible growth on the surface of the caulk. Additionally, if the caulk feels soft or spongy, it could indicate moisture trapped underneath, which is a breeding ground for mold.

Sewer gas in any location can cause eye and respiratory irritation if you’re exposed at low levels, or more severe symptoms if you’re exposed at high levels—but fortunately, the fresh air outside means it’s less likely to affect your physical health. However, sewer smells outside can still indicate significant plumbing problems that will need to be dealt with, such as a potentially damaged sewer line or roof vent pipe.
