Local considerations in Sterling Heights & Macomb County

We regularly get calls from new Sterling Heights homeowners who inherited a security system from the previous owner — sometimes an old ADT or Brinks panel, sometimes a generic builder-installed system with no active monitoring. In most cases we can assess what's there, tell you honestly whether it's worth reactivating or replacing, and get it operational without starting from zero.

Older homes in ZIP codes like 48310 and 48312 sometimes have legacy wired systems from the 1990s–2000s still on landline-based signaling — since many Michigan landline services have been discontinued or degraded, we frequently upgrade these to cellular communicators so monitoring keeps working reliably.

What it costs

Diagnostic visits typically run $75–$150, often credited toward any repair performed. Sensor and battery replacement typically runs $20–$80 per device including labor. Panel or communicator upgrades (e.g., landline to cellular) typically run $150–$350.

Every quote is based on an on-site walkthrough — we don't sell fixed "packages" that leave gaps in coverage or charge for equipment you don't need. See our full 2026 cost guide →

Frequently asked questions

Can you service a system you didn't install?

Yes — most of our repair calls are on systems installed by a previous owner, builder, or another company.

My panel is beeping — is that an emergency?

Usually not — it's most often a low battery, a sensor fault, or a communication issue. Call us and we can often troubleshoot over the phone before scheduling a visit.

Is it worth repairing an old system or should I replace it?

Depends on age and parts availability — we'll give you a straight answer on repair vs. replace cost during the diagnostic visit.

Can you switch my monitoring to your company without new equipment?

In most cases yes, provided the existing panel is compatible — we'll confirm during the assessment.
