ASPEN ENVIRONMENTAL IS THE PREMIER MOLD REMEDIATION COMPANY IN NEW ENGLAND FREE ESTIMATES – (800) 931-MOLD We have the professional certifications and experience not only to clean and remove any mold issues you may have, but to take the corrective measures to insure it won’t happen again. Most companies are not certified in toxic mold removal. All they do is a “cleaning”. This usually does not kill the mold spores, and they grow back in a short time. We follow the strict standards of NORMI (National Organization of Remediators and Mold Inspectors) and the IICRC (Institute of Inspection, Cleaning, and Restoration Certification).
