Customer Testimonials

I have worked with DIY Alarm for over 20 years at both my home and business. Dave L. provides terrific support on any install, troubleshooting or upgrade issues. His product fees are very competitive and the monitoring service at Central Station handles all issues promptly and professionally. I couldn't be more satisfied with this security system and Dave's service.                          Hugh R Phillis, DMD - Nashua, NH

I’ve known Dave Lemay from diyalarms for a long time. I’m now on my third system from him and I have to say, I’ve never had better service from any vendor. He not only recommends a system and programming suited for your needs, but talks you through the setup, makes any adjustments necessary and is available to solve any problem with phone response faster than other vendors or services. He talks alarm systems with no bs and you can be sure you won’t be enticed with a price for a basic system and then find out later, what you bought doesn’t meet your needs. I trust Dave and High Level Alarms and I highly recommend that if you want a good alarm system, this is the one for you. Al S., Londonderry, NH
