"Very satisfied with the whole process. Gerald did an excellent job. Arrived punctually and observed COVID protocols. Explained clearly what he was going to do and how. Showed us preliminary findings, and obtained our permission to take samples for lab testing. We felt he listened to, and responded to, our concerns. Overall a very professional experience. We’ve now received the written report and feel we got what we wanted: an objective analysis of the problem and information we need to remedy it."

Biohazard Remediation FAQs, answered by experts

Ensure proper ventilation, fix leaks, and schedule regular pest inspections to protect your property.

Vinegar and bleach are effective options for removing mold from drywall. Vinegar is a better choice if you have a smaller mold issue while bleach is best if you have a larger mold problem. If the area you're cleaning has limited ventilation, using vinegar would be a better option. In that case, you could mix vinegar with baking soda to remove more stubborn mold growth.

Yes, outside leaks can easily cause damage to your home if you don’t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home’s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.

Once again, contact with moisture is the culprit here, though water-resistant varieties of wallpaper are less likely to become wet and develop mold. Using a high-quality exhaust fan or dehumidifier and leaving the doors or windows cracked after bathing will keep this issue at bay. 

Yes, it is safe to clean silicone caulk with bleach, but proceed with caution and don’t use bleach as part of your regular maintenance cleaning. Always wear protective gear like gloves and a mask, and ensure the area is well-ventilated to avoid inhaling fumes. Never mix bleach with other cleaning products, especially those containing ammonia, because this can create hazardous fumes. Properly used, bleach effectively and safely removes mold and mildew from silicone caulk in severe cases.
