John L. Carter Sprinkler Company, Inc. is a leader in designing, installing, and maintaining fire protection sprinkler systems. Founded in 1978, the company installs municipal, commercial, and residential sprinkler systems along with special hazard sprinkler systems in New Hampshire, Vermont, and Maine.
Although the company has installed fire protection in all types of buildings, the Carter Sprinkler design team and mechanics specialize in the craftsmanship of retrofitting sprinkler systems into existing buildings. The craftsmanship and attention to detail required for retrofits in existing and historic buildings is a source of pride with the company. Carter Sprinker has one of the most experienced work forces in the industry—the foremen have an average of 15 years of experience and the designers average 20 years of experience. Our design team has six NICET certified designers, including three NICET level IV designers, significantly more than any other related company in the state.
