What Giertsen Company does

Giertsen Company is a privately held, fourth-generation family-owned restoration and exterior services contractor founded in 1918 by Walter D. Giertsen in Minneapolis, Minnesota. The company operates two primary divisions: a Restoration Division providing 24/7 emergency response, mitigation, and reconstruction services for fire, water, and wind damage across residential, commercial, multi-family, institutional, and healthcare properties; and an Exterior Services Division delivering roofing, siding, gutter, and capital improvement construction for commercial, multi-family, and residential clients across the Midwest. Giertsen targets property owners, insurance adjusters, property managers, and commercial clients, with a one-hour on-site emergency response commitment for storm events.

The company's service delivery rests on specialized restoration technology and industry-standard tools rather than proprietary software. Capabilities include Matterport 3D scanning for comprehensive loss documentation, thermal imaging cameras and moisture mapping systems for water damage assessment, Hover 360 digital measuring for exterior projects, and industrial water extraction, air scrubbing, and structural drying equipment. Operations integrate with insurance estimation platforms (Xactimate/Symbility) and content inventory software (Assured Software) to streamline claims processing. Field staff include IICRC-certified technicians and production managers averaging 15+ years of experience, supporting the company's positioning around speed, documentation quality, and adjuster-friendly reporting.

Giertsen's business model is sales-led and project-based. Revenue is generated through emergency response contracts, insurance claim-driven restoration projects, commercial bidding for capital improvements, and long-term relationships with multi-family and commercial property managers. Pricing is quote-based and not publicly disclosed, and the company emphasizes working within insurance carrier programs to determine scope, timeline, and repair methods. Demand is sourced through 24/7 emergency phone lines, insurance industry referrals, property management association partnerships, and content marketing including newsletters, video case studies, and educational resources. The company operates from three regional offices in Golden Valley (MN), Waukesha (WI), and Buffalo Grove (IL), with leadership distributed across fourth-generation family members and a long-tenured general manager.
