An Alarm Company You Can Trust

For close to 50 years our family has provided friends, neighbors, small businesses and large with the best systems around. Now, with our third generation learning the ropes, we hope to continue for many more. Our employees live, play and work here, giving back to the community, supporting other local businesses.

 

No Hidden Fees

We don’t use bait and switch sales tactics. We don’t quote a minimal system and try to upsell you at the time of install. We set out all options and pricing up front and deliver guaranteed pricing for 30 days. These are important factors to keep in mind while comparing estimates which often contain variances like minimal or even missing equipment in order to show a low price.

We care about more than your tools

Sure a burglar alarm system is a great protection tool but we care a lot about people’s lives. Monitored combination smoke/carbon monoxide detectors can provide critical notification if someone is overcome by smoke inhalation, breathing poison gas, or gone from home when a fire starts. And those nasty water leaks! They can cause thousands of dollars of damages if not caught quickly. To us, those are some of our most important tools.

 

Insurance Discounts

Most insurance companies offer homeowners a premium discount for having a monitored alarm system, and an additional discount for fire devices. These discounts are often greater than the expense of monthly central station monitoring. Check with your insurance agent about available savings.
