If you suspect that your home or business has a mold problem, Continental Remediation Services can inspect and assess your property. If mold is found, we have the training, equipment, and expertise to handle the situation. We provide 24/7 emergency service!

Mold Testing and Remediation questions, answered by experts

Determining if vermiculite contains asbestos requires professional testing. Visual inspection alone cannot confirm the presence of asbestos fibers, as these fibers are so small that they are not visible to the naked eye. A certified asbestos inspector will collect samples of the vermiculite insulation and send them to a laboratory for analysis. Microscopic examination using polarized light microscopy (PLM) or transmission electron microscopy (TEM) is necessary to accurately identify asbestos fibers. DIY sampling is strongly discouraged due to the potential health risks associated with asbestos exposure.

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.

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.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.

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.
