Aspen Environmental is the Premier Company for Mold Remediation in Massachusetts, New Hampshire, Greater Boston, and New England. We have the professional certifications and experience not only for cleaning mold and removing mold that you may have, but for taking 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 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).
