The equipment used in carpet cleaning, when combined with specialized drying equipment, is well suited for many damage circumstances. However, in more severe loss conditions, a trained damage restoration contractor may be better able to address the unseen damage, such as water hidden in walls and under cabinets. The agent probably has experience with one or more reputable companies. Look for professional affiliation with a relevant trade association. The Association of Specialists in Cleaning and Restoration and its divisions, including the Water Loss Institute and the National Institute of Disaster Restoration, offer continual education for damage contractors.
Membership is an indicator of industry specific knowledge.
Ask for their certification. Look for a company that has a water loss specialist or a certified restorer on staff. These are designations earned with time, training and testing. The International Institute of Certification in Restoration and Cleaning is an organization that approves training and then certifies individuals and firms that meet their testing requirements. Be certain the certification is in the area of water damage.
