When Glass Breaks, Your Security at Home or Business Shouldn't.

Security Window Film helps turn vulnerable glass into a stronger barrier against forced entry.

When an intruder strikes a window or glass door, the goal isn't necessarily to make the glass impossible to break. It's to slow them down, hold shattered glass together, and buy valuable time for your security system, monitoring service, or emergency response to do its job.

Diversified Security can help protect storefronts, offices, commercial buildings, and other vulnerable entry points with professionally installed security window film.

What Our Clients Are Saying

Ayman D. - Chester, NJ

Just a quick thank you to your technician who was able to fix my alarm system. He did a great job and was awesome to work with. He also gave me the ability to cancel my phone line which I never use.

Lou C. - Spring Lake, NJ

I am very happy with my alarm upgrade and the work that your technician, Dixon, had done. I truly appreciate his hard work. By adding smokes and carbons, I will be saving $200/year on my homeowner’s insurance!

Scott W. - Chatham, NJ

I have worked with many technicians over the years and have gained enough “hands-on” knowledge to probably make me dangerous but I’ve also been exposed to many technicians, some good, some not so good. Your technician that helped me is definitely one of the “good” ones. He was very accommodating and knowledgeable. He took the time to listen to my needs and questions and came up with the best solution for me. He also took the time to show and explain the work he did. He definitely met my needs.

Laura T. - Rumson, NJ

I have found Diversified to be very responsive and helpful. From the initial consultations, their staff explained everything they were recommending and answered all our questions. Moreover, going forward, each time I have raised a concern they address it promptly and schedule whatever service I need. Finally their service people are knowledgeable and resourceful. I feel good knowing they are in charge of our security system.

Jim C. - Short Hills, NJ

I own my own company and know how valuable good customer service is. This past Sunday my alarm system started to act up. The on-call technician put me through to your representative. She was very cordial and helpful. She walked me through the process to address the issue and followed up as promised. I ended up speaking with her on the phone a few more times and she was always the same – pleasant, helpful and concerned. As a fellow businessman, I hope to use this opportunity to reward your representative and thank her for her time!

Debbie P. - Westfield, NJ

I wanted to take a moment of your time to once again share my opinion of your staff. Your technicians are fabulous! They are always helpful and make me feel like they genuinely care about whatever situation is taking place. Your customer service representative goes beyond the call of duty and she is always helpful.

Michelle D. - Holmdel, NJ

We couldn’t be happier with Diversified Security. From sales to service and everything in between, they are professional, efficient and timely. They handled our security system as well as our phone. Their standard of work is excellent. We are extremely satisfied clients!
