Home Security in Newcastle, OK
Newcastle grew about 38% from 2020 to 2025, and it's now the largest city in McClain County. It's bordered by Oklahoma City to the north and the Canadian River to the northeast, with I-44 and Main Street (U.S. 62) running through town, and much of the growth is new subdivisions on what used to be farmland.
New homes come with their own blind spots: a builder doorbell that doesn't see the driveway, a back fence with open field behind it and a garage door left up overnight. If your builder put in a system, we can often take it over and add to it. If not, we'll design one around how your family actually uses the house, with cameras, a monitored alarm system and smart locks.
Newcastle has been hit by tornadoes in 1999, 2011 and 2013, so every alarm system we install has battery backup guaranteed for 72 hours or more.

Good questions, straight answers.
Should I wait until we're moved in?
You don't have to. We can install before move-in, or within your first week, so your new codes and cameras are ready from day one.
Our builder installed a basic alarm. Can you work with it?
Often, yes. We'll look at what's there, take it over if it's worth keeping and tell you what, if anything, you'd add.
Do you serve all of McClain County?
Yes. We serve Newcastle, Blanchard, Purcell, Goldsby and the rural areas in between.
