Over 1,000 Cases of Water Damage Investigated

Fire investigation is a complex and detailed science that combines data from several different disciplines to include but not limited to, fire science, fire chemistry, explosion dynamics, computer fire modeling, failure analysis, and electrical systems.
Our investigations are conducted utilizing the latest scientific principles and methods, including those outlined in NFPA 921 and 1033 documents. We employ multiple, certified investigators who have years of training in fire origin and cause determination. Our investigators have fire department backgrounds and are certified by multiple agencies that require continuous training in order for the certifications to remain active.
Like fires, water losses and intrusions need to be properly investigated by qualified, highly trained personnel in order to identify the origin, cause, and subrogation potential. Most water losses occur as a result of manufacturer or construction defects or improper installation of plumbing or roofing components.
A complete origin and cause analysis can reveal factors concerning the ignition source, material first ignited, fuel, fire spread, and building systems that resulted in the ultimate extent of fire and smoke damage.
The codes and design standards involved can be included in the analysis, as well as construction, operation, and maintenance practices.
