Guardian Preservation Services was founded on over 20 years of industry experience and the breakthrough Oceanic enzyme solution. We are one of the only companies in the nation with proprietary rights to use this remarkable mold remediation method, which simply makes all past methods obsolete.

Since its inception in 2007, Guardian Preservation Services has grown from a local mold remediation company based in Tinley Park, IL to include nationwide coverage with offices in Texas, Florida, and Indiana. Through strong partnerships, referrals, and satisfied customers, our company revenue has doubled each year.

The secret to our rapid success is very simple: proven results. We are one of the few mold remediation companies that offers a lifetime guarantee on our work. This is because we have absolute faith in our services, and, once our customers see the results, they unequivocally agree.
