On installation day he and his coworker were here from 9am-6pm, they worked really hard with wiring and setting up 5 cameras for us. Once done he went over everything with us, moved camera angles as needed and explained how everything worked. I highly recommend him to anyone looking for camera installation, Jose is a true professional and a really nice guy!

I reached out and Don came by the next morning, and gave me a quick and simple quote that blew the other guys out of the water. He was quick and professional, and fully delivered with terrific quality cameras. We have had two small issues since then (not to do with the quality of work, just minor snafus) and Don responded to me right away and helped me fix the problem. These guys will be my first call the next time I need anything like this.

I had to use another company in between my two times and was very dissatisfied and that experience made me realize how much better Dupage Security Solutions is. Dupage Security Solutions technicians are responsive, timely, affordable, professional, thorough, patient, and they explain everything step by step, tell you your options, and get your permission before moving forward on another step. I called this most recent technician "my hero" and he humbly smiled and went on his way. :) They aren't 24 hours (that's why I had to try another company- next time I will wait!) so keep that in mind. They do many other things- check them out at www.dupagesecuritysolutions.com.

About 2 weeks ago I signed up for conceal & carry classes with Glenbard Security. I was…read moreapprehensive as I'm not a regular client at shooting ranges but was considering becoming one, and I wanted to know more about the carry/conceal aspects of owning a firearm in Illinois. The classes are priced competitively, take 16 hours which included qualifying time at a local range, and had ten people attending. Much of the classroom material consists of the Illinois State Police worded laws and restrictions, but the instructor Jason took the time to explain anything that wasn't clear. Being in law enforcement, Jason also shared plenty of practical experience and videos of real-life situations. If you are considering a conceal & carry class I recommend Glenbard Security.

Because my project involved a custom door replacement that required condo association approval, custom ordering, painting, lock placement, and installation, there were several phases involved. Throughout it all, the team remained professional, responsive, organized, and attentive to detail. Walter, the locksmith technician who handled the project from beginning to end, did an outstanding job. His workmanship, professionalism, and attention to detail truly stood out, and the finished result exceeded my expectations. Chicago Locksmith is lucky to have someone such as Walter that is extremely skilled, professional and pleasant to deal with. I also want to recognize the Chicago Locksmith office staff for their excellent customer service and communication throughout the process. Everyone was courteous, helpful, and a pleasure to work with. Overall, I highly recommend Chicago Locksmith for their professionalism, quality work, and outstanding service.
