Seacoast Security Continues Growth in Maine

October 14, 2022

Seacoast Security, Maine’s top voted residential and commercial security company across Maine, announced its purchase of Rennie Security Systems, Inc. This acquisition adds approximately 300 additional residential and commercial customers to Seacoast Security’s portfolio in southern Maine.

Rennie Security has operated in Saco, Maine for 42 years, and offers home and commercial security installations and service throughout southern Maine. While many small companies have sold out to large muti-national corporations who out-source monitoring services to out of state call centers, Seacoast Security has continued to work to acquire these companies and keep the jobs here in the state of Maine.

Seacoast Security is the largest self-monitoring security company in the state of Maine. Over the last 50 years, Seacoast Security has grown from a small security company, based in West  Rockport, Maine, to offer state-wide coverage as well as service in New Hampshire and Vermont. Seacoast Security has maintained its operations in West Rockport and employs Maine people for all of its security dispatch operations. Currently, Seacoast Security employs 117 people to serve their thousands of customers across the three states.

“There are no better people to service our customers than people who know what it’s like to live and work in the states our customers call home.” said Vice President and Owner, Stephen Haynes. “We’re all experiencing the same challenges, same weather and same tragedies at the same time.” Haynes goes on to explain the challenges of maintaining your own monitoring center; “The job is tough. It’s tough keeping our monitoring center staffed 24/7, tough to keep people trained and tough to find the right people to do the job for our customer’s day in and day out. We are very fortunate to have a team of people who enjoy and excel at their jobs. We know we are doing the right thing because we hear it from our customers daily. Our Dispatchers are saving lives at work while raising their families in beautiful mid-coast Maine.”

Seacoast Security, in addition to investing in Maine jobs, also invest in all the communities they serve. Seacoast Security runs a trades scholarship program, which provides scholarships to two Maine students each year that are attending a Maine trade school.
