About

Hampshire Fire Protection Co., LLC is a well-established commercial fire protection company headquartered in Londonderry, New Hampshire, serving the Northern New England region — including New Hampshire, Massachusetts, Maine, and Vermont — since 1978. The company was founded by Larry Thibodeau, who transitioned from a summer fire protection job into building one of the region’s largest fire protection contractors. Since its inception, Hampshire Fire Protection has grown from a small local business to a major provider of fire safety systems, earning more than $21 million in yearly sales while remaining family-owned and managed. Hampshire’s core mission is to deliver comprehensive fire safety solutions that protect people, property, and business continuity. Its service portfolio includes fire sprinkler system design, engineering, fabrication, installation, and 24/7 maintenance service, ensuring the systems function reliably when needed most. The firm’s design department leverages advanced tools like BIM (Building Information Modeling) to produce precise layouts that streamline installation and permit approval processes. In addition to sprinkler systems, Hampshire Fire Protection sells and services fire alarm systems — including being an authorized distributor for Potter alarm products — and fire extinguishers with a full assortment of Amerex models and restaurant fire suppression systems. Annual inspections, hydrostatic testing, recharging services, and ongoing system checks are offered to help clients remain compliant with current fire protection codes. The company also places value on community involvement and industry recognition, earning repeated rankings in ENR/Engineering News-Record’s Top 600 National Specialty Contractors and recognition from Business NH Magazine among top family-owned and private companies. Hampshire supports many local nonprofits, civic programs, youth organizations, and fire safety initiatives across the region, illustrating a lasting commitment beyond just commercial service. With multiple regional offices and a focus on dependable service, Hampshire Fire Protection continues to grow while maintaining technical capabilities, personalized customer care, and safety-oriented practices built over nearly five decades.
