Why homeowners call us
Why Northline
-
One crew for low voltage and high voltage
Cameras, speakers, network cable and the circuits behind them are handled by the same licensed team, so nobody waits on another contractor.
-
Written quotes, no pressure
We walk the house, then send an itemized quote. If you want to think about it, that's fine. We won't call you every day.
-
Clean installs
Wires run inside walls where the house allows it. We patch what we open and clean up before we leave.
-
We show you how it works
Before we go, we set up the apps on your phone and walk you through the remotes, the cameras and the alarm.

How it works
From first call to finished install
-
Tell us about the project
Use the form or call. A short note about the house and what you want is enough.
-
Site visit
We look at the space, the wiring and the network, and answer your questions. Usually 30 to 60 minutes.

Written quote
You get an itemized quote with equipment, labor and timing. No obligation.
-
Install and walkthrough
We install, test everything, clean up and show you how to use it.
Common questions
Do you charge for a quote?
No. The site visit and written quote are free.
Do I have to sign up for alarm monitoring?
No. We can set up professional monitoring, self-monitoring through an app, or no monitoring. We'll explain the trade-offs and costs.
Can you work with equipment I already have?
Often, yes. Tell us the brand and model and we'll say honestly whether it's worth keeping.
Do you pull permits for electrical work?
Yes. When the city requires a permit, for example for a panel upgrade or a new EV charger circuit, we pull it and schedule the inspection.
What areas do you serve?
Plano, Frisco, McKinney, Allen, Richardson and nearby cities, roughly 30 miles from our shop. If you're a little farther out, ask anyway.
