Introduction first.

The faces behind the names

Mason Alarms was first formed as 'P.L. Mason Alarms' in 2005. Founders Peter and his daughter, Morgan, cut the name to simply 'Mason Alarms' in 2010. We soon grew to include Colt, Kasie, and Barry. Our small group of family and friends enjoy providing service to clients throughout New Hampshire.

  • Protect people where they work and live with life safety products and services.  
  • Support our clients by fully supporting the systems that protect them.

Our mission is to earn the community’s trust by providing highly dependable systems that enrich their lives.

  • Unwavering Integrity
  • Reliability & Dependability
  • and above all, Trustworthiness

What do YOU need for security?

What your neighbor needs may not be the same as what YOU need.

Every client is unique. So, we first listen to you, and then offer solutions that make the most sense.

What's new with Mason Alarms?

Most recently, we have purchased a Main Street location in Tilton. To find us, take Exit 19 or 20 off Route 93, go West about a mile. After renovations in late 2018, we will open New Hampshire’s first retail showroom for the DIY tinkerers and anyone else with an interest in alarm systems.​
