GCI Consultants Proven Process

Qualify, Research, & Review

We review all of the documentation about your building including its original construction and repair history, maintenance records, before-and-after photographs and videos, and weather data from the day(s) the damage occurred.

Investigate & Assess

We do a visual investigation of your damage looking for clues such as wet drywall and mold. We bring along the proper equipment and investigative tools to provide additional data on the damage.

Analyze, Strategize, & Report

Next, we develop an appropriate testing protocol based on our historical research and our on-site visual investigation. Through the on-site testing we’ll isolate various components and likely remove finish materials to view inside cavities and trace the leakage paths back to the sources. Once testing and review of the results is completed, we will provide a thorough, state-of-the-art report and recommendations.

Defend & Testify

We will provide consultation with expert input about claim resolution, including presentations and consultations at mediation and arbitration proceedings. Our experts team will conduct testimony at depositions and trials.
