At Tri State Flood Inc, we specialize in comprehensive disaster restoration services. Our team is dedicated to safeguarding homes and businesses from the damaging effects of water, fires, mold and storms. Here’s what sets us apart: Water Removal and Storm Damage Restoration: When water wreaks havoc due to storms or other incidents, we’re here to help. Our 24/7 emergency response team swiftly tackles water extraction, drying, and structural repairs. Comprehensive Services: Beyond mold and water remediation, we handle storm damage repairs, basement flood cleanup and fire restoration. Choose Tri State Flood Inc for reliable, efficient, and compassionate restoration services. We’re committed to restoring peace of mind and protecting your property.

"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

Mold Testing and Remediation questions, answered by experts

Inhaling smoke from burnt food can be harmful to your health. Smoke and strong odors released when food burns can cause respiratory distress, especially for people with health conditions like asthma or for pregnant people. Even for those without such sensitivities, burnt food smoke can cause lung inflammation and irritation when inhaled.

Mold on window sills is common, especially in damp or poorly ventilated areas. Windows are prone to condensation, which creates the moisture mold needs to grow. Dust, dirt, and other debris on the sills can further feed mold spores. While it’s not unusual, it should be addressed quickly to prevent further growth and potential health risks.

The CDC does not consider diatomaceous earth toxic to humans or animals, though it can cause skin, eye, and lung irritation when handled without PPE. It's important to note that non-food-grade diatomaceous earth can be toxic when handled or consumed, so homeowners should only purchase the food-grade option.

The gasket and drum of a washing machine are ideal spots for mold to grow. They are dark, warm, and humid, conditions that mold thrives in. The products you use to wash your clothing, such as fabric softener and detergent, can also encourage growth by giving the mold a food source.

Black discoloration on your attic insulation may be caused by buildup from soot, dust, or dirt, which does not come with dampness or a musty odor. However, another cause of black discoloration on attic insulation is black mold, which has a musty smell and other signs of damage. If you’re unsure what black stuff you’re looking at, consult a pro to be safe.
