Licensed New Hampshire Private Investigator
Private investigator services in Portsmouth, New Hampshire
Kreymer Investigative provides surveillance, background checks, infidelity investigations, skip tracing, and insurance-fraud investigations for clients in Portsmouth and throughout Rockingham County — backed by court-admissible evidence and a nationwide investigator network for cases that cross state lines.
Local coverage & context
Portsmouth is the anchor city of New Hampshire's Seacoast region, reached by I-95 and the Route 1 Bypass. Our investigators are familiar with the area around Market Square, Strawbery Banke, the Piscataqua River waterfront, and Pease International Tradeport, and we run cases here regularly for clients who need boots-on-the-ground local knowledge, not a generic statewide template.
Portsmouth's tourism economy, seasonal rentals, and tight-knit downtown mean discretion matters as much as evidence quality — our surveillance work here is built around a city where people tend to know their neighbors.
