Therrell Alarm Protection Service

Recently had our Alarm system upgraded and the work was done quickly, we got great operating instructions, and the remote access functions are awesome! Thanks Y’all.

I have used Therrell Alarm both for my home system and to install an upgraded security system for our church. The later was an extensive project involving multiple phases. Throughout, they were knowledgeable, courteous, and prompt. I highly recommend them.

You'll be happy and safe if you choose these guys! Absolutely can't beat having their services.
