They did a great job, very professional and friendly. They actually were able to help me over the phone instead of coming out and charging me. I will be using them soon to do work on my system. Great service!

i hired them to install burgalar alarm system, they did an excellent job. I have used them in the past. Their technicians are knowledgeable, courteous, and neat. they also monitor my security system, their monitoring services are very effective, i would highly reccomend this company.

I have been using Naperville Alarm for my company for over 6 years. They provide great service with very reasonable prices. Employees are always polite and professional and have excellent technical support. I recently moved my business to a new location and they did very good job with installing new system and connecting everything to the monitoring company. I highly recommend their service to any home or business owner
