Every credential is verifiable.

Statewide commercial + residential building contractor license. KB-1 Dual covers structural restoration and reconstruction across both classifications — the broadest residential/commercial scope a single license can hold in Arizona.

Dedicated AZ commercial + residential roofing license. CR-42 lets DRR self-perform full roofing scopes during restoration without subcontracting — important when a fire, storm, or water loss requires coordinated structural + roof work on a tight timeline.

IICRC-certified firms commit to the consensus industry standards for water (S500), mold (S520), fire (S700), trauma (S540), and HVAC (S540) restoration. The firm certification is renewed annually and requires multiple individual technician certifications on staff.

Authorizes asbestos abatement on regulated materials per the Asbestos Hazard Emergency Response Act. Required for any work disturbing materials in pre-1980 commercial buildings or schools — a common scope on Phoenix-area mid-century construction.

OSHA's 40-hour hazardous-waste-operations training plus annual 8-hour refresher. Required for crews working biohazard, chemical-spill, sewage, or industrial-hazmat events. Covers respiratory protection, decontamination, and incident-command-system protocols.

Healthcare-environment infection-control protocols for restoration in active patient-care facilities. Class III–V covers full-containment work in hospitals, skilled nursing, surgical suites, and similar high-acuity settings — negative-air, HEPA filtration, traffic flow management, and PCRA compliance.

DRR maintains an accredited profile with the Better Business Bureau. BBB accreditation requires meeting BBB's standards for trust, including responsive complaint handling and truthful advertising — both of which are reviewed annually.
