Real talk from our service techs: the #1 thing we hear on house calls is "I've been meaning to get this fixed for months."

The beeping panel. The camera that's been offline since spring. The sensor that fell off the window in 2023 and lives in the junk drawer now.

We get it — calling the alarm company usually means an hour on hold and someone reading a script while YOU do the fixing.

So we do it the old way: a real tech, in a real van, at your door. We service any system, any brand — even ones we didn't install. Most fixes happen in one visit, explained in plain English.

We're running routes all across Greater San Antonio this week — Leon Valley, Helotes, Schertz, Shavano Park, Kirby and everywhere between.

If your system's been "on the list" for a while, this is the week: texashomesafe.com or (866) 665-2210. Takes about 60 seconds to book.

Samuel was paying ADT $63.99 a month in monitoring. Locked into a 36-month contract. He assumed his home was fully covered.
Then he sat down with us and we walked his house.

What he actually had: a panel, two door sensors, and one motion detector. No cameras. No glass break sensors. No coverage on any windows. If someone broke a window in the middle of the night — nothing. No alarm. No alert. No one coming.

Three years of payments for a system that barely covered the front door. And that bill was going up every year.

What he got with ASG: sensors on every entry point, three outdoor cameras, glass break detectors, smoke and CO monitoring, a Honeywell smart panel with key fobs — and local cellular monitoring for $9.99 a month. Month-to-month. No contract. His equipment package was custom built for his home's layout.

His monitoring dropped from $63 to $9.99. That's real money back in his pocket every single month.

Samuel's review is on Google right now. So are dozens more from families across San Antonio who made the same switch — from ADT, from Brinks, from Vivint.

If you want to know where your home actually stands, we'll walk it with you. Free. No pressure.

Last July it hit 107° in San Antonio. It'll happen again this summer.

Most cameras aren't built for that. They overheat. They fog. They drop connection when the power goes out during a thunderstorm.
And that Ring doorbell on the front porch? It's covering one angle on one entry point.

Every outdoor camera we install is weather-rated for Texas heat. Solar-powered 360° units that charge themselves. Battery backup on every panel. Equipment that works through the worst this city throws at it — because we live here too.

We don't ship a box from a warehouse in Ohio and hope it holds up. Our licensed technicians install everything themselves and they know this climate because they work in it every single day.

Monitoring: $9.99/mo. Custom packages: $44.99–$129.99. No contract.

Stone Oak. Leon Valley. Helotes. Hollywood Park. Timberwood Park. Alamo Heights.

Families across San Antonio are switching to ASG Security. And once that yard sign goes up, the neighbors start asking questions.

"Who installed that?" "How much is the monitoring?" "Is it better than what I have?"

The answer is almost always the same — they didn't realize how little of their home was actually covered until someone walked it with them.

We monitor every entrance on local cellular for $9.99 a month. No contract. No rate hikes. Equipment is custom priced based on your floor plan — not a one-size-fits-all box.

Your neighbor already made the call. Have you?

Here's something most homeowners don't think about until they're three years deep.

That monitoring bill you signed up for? It went up. And it'll go up again. And you're locked in.

Year 1: $50/mo. Year 2: $63.99/mo. Year 3: $75/mo. Year 5: $85/mo. Still locked in. Still paying. Still covering the same front door and hallway.

That's over $2,700 in monitoring alone over three years. For a system most families don't even realize barely covers half their home.

ASG Security charges $9.99 a month for local cellular monitoring. Month-to-month. No contract. No rate increases. If you want to cancel, you cancel. No fees. No calls. No fine print.

That's $359 over three years. You keep the other $2,341.
Equipment is custom tailored — $44.99 to $129.99 depending on your home's layout. Not a package. A plan.

Your monitoring bill should protect your home. Not drain it.

It's 3:00 AM. Everyone in the house is asleep.

Someone tries the back sliding door. Then the side garage entry. Then a window.

In most homes across San Antonio, nothing happens. No alarm.

No alert. No dispatch. Because those entry points were never monitored in the first place.

The alarm industry has been selling the same thing for twenty years — a panel, three door sensors, and a motion detector.

That's the "package." And they charge you $55, $63.99, even $85 a month for it. Locked into a contract that only goes up.

We walk your home. We count every way in. And we build a system around your actual floor plan — not a box from a shelf.

Monitoring: $9.99 a month. Month-to-month. No contract.
Custom systems: $44.99–$129.99 based on what your home needs.

We don't write our own headlines. Our customers do.

Harry switched from Brinks. His home had no window sensors, no cameras, and no glass break detectors. He was paying every month for a system that left his family exposed.

Samuel switched from ADT. He was skeptical at first. Now his entire home — every single window — is covered for under $65 a month.

Rachel switched from Vivint. She never had the window sensors or the 360° cameras she actually wanted. Now she does.

George was new to ASG. Carson came back to his house twice after the install just to make sure everything was working the way it should.

These are real Google reviews from real San Antonio families. We didn't ask anyone to say anything. They just did.

If you're paying for a system right now and you're not sure what's actually covered — message us. We'll walk your home for free and show you.

Samuel and his wife made the switch from ADT to ASG.

He'll be the first to tell you — he was skeptical. They hadn't heard of us before. But after talking with Andrew, who was patient, upfront, and took the time to actually explain everything, they decided to try it.

His words, not ours:
"We're so glad we did. I never thought we'd be able to get full coverage — including every single window — for under $65 a month. And the 360° spotlight camera? Clear as day, even at night."

That's a verified Google review from a real family right here in San Antonio.

100% of windows covered. 360° spotlight cameras. 24/7 recording for 30 days. All for less than what most people are already paying for half the coverage.

If you've been thinking about it — or you just want to know what your current system is actually missing — message us. We'll walk your home for free and show you.
