I had three doors replaced in my house and garage. I haven’t painted the trim yet but the alarm sensors had to be reinstalled. The service technician Mike did a great job. He was prompt, courteous and professional.
I couldn’t ask for better service.
Hopefully Mike gets some recognition for his fine work.

Writing for Paws and Whiskers Cat Shelter. Rudy was an excellent tech who made sure all of our cameras were right where they needed to be. He talked us through the process of installation of our new cameras, then also made sure we understood the app. I highly recommend Guardian and highly recommend Rudy to be your technician.

They sent a few text messages through the week to notify appointment. Once the day of appointment was here, they called and confirmed the 1 to 2 hour window they were showing up. 30 minutes before they called to make sure we were still home and ready for their arrival. They showed up and fixed the problem within 10/20 minutes.
- great communication
- great service
