The first step in solving an indoor mold problem is ALWAYS stopping the source of moisture. Mold will begin to grow on porous surfaces within 24–48 hours. First Response Restoration Services will find the source and dry the area without spreading the mold dust and spores. Protect your health and let us eradicate the mold before it causes health problems. The goal of remediation is to remove or clean contaminated materials in a way that prevents the emission of fungi and dust.
