"Working with Rush security has been highly disappointing and mediocre at best. We had multiple missed appointments with their technician until I put my foot down and said I'd cancel service if they did not show up. He started to show up after that, but just for a couple days and in my opinion still did subpar work. At first, the alarm system would not register away, only "stay". Then the doorbell camera was constantly ringing even when no one was there. The motion detector also does not work. Next, we paid $400 for equipment and a $75 monthly monitoring. I wish I would just gone with Ring because they are cheaper but I wanted to support local. When we asked to cancel we were told we'd have to pay a 1400 cancellation fee to recoup the loss of having an electrician come out and for the 'low' $75 monitoring and to buyout the contract. Initially, we were told they offered no contract service, which was the only reason we went with them. I did the math and that 1400 fee would total out to about 1.5 years of subpar service. No thanks. We took the loss but you do not have to, go with someone else or just install your own alarm"

We are a new company trying to stand out by providing low prices, free consultations, excellent customer service, and unbeatable quality on our installs in comparison to the current industry standards. We are based in Morrison and serve everywhere within 2 hours of Denver, and we are open 7 days a week, so if a customer ever has a question or concerns with their system, we can send a technician to get them taken care of as soon as the very same day!

"From consult to install Jack and Eric were extremely friendly and helpful. They asked questions to make sure that the products chosen made sense for my home and situation. After install, they walked through each piece of equipment and explained how to use them with the phone aps and in practice (arming/disarming security system, setting up codes and new users etc.) and made sure I was comfortable with all the things (cameras, security control box and so on). Would absolutely recommend and will use again in the future if I move or decide to change/upgrade."

"I've been using ADT Home Security for over a year now, and it’s been worth every penny. The peace of mind it gives my family is priceless, but the cost is surprisingly reasonable—just $99.99/month for the Smart Home package. The installation was quick and professional, and the technician took time to explain everything. I love being able to control the system from my phone, and the instant alerts are super reliable. The customer service has also been excellent whenever I had questions. With 24/7 monitoring and smart home integration, I truly feel my home is protected at all times.

FAQs for alarm or security system installation projects in Westminster, CO

If you terminate your security system before your contract ends, you’ll likely have to pay a cancellation fee—often a percentage of the remaining contract balance. To avoid these fees, consider choosing a brand that offers contract-free plans, like SimpliSafe or Vivint. You can also negotiate with your provider to see if they provide pro-rated cancellation fees or special exceptions.

Paying for a security system is a valuable investment because it enhances your home’s safety and deters criminal activity. With millions of property crimes each year, having robust security measures helps protect your property and might even lower your insurance premiums. It's a worthwhile investment for lasting peace of mind.

The average cost to install security cameras ranges from $125 to $3,500, depending on the amount, type, and placement. To install a complete setup of four cameras, homeowners can expect to invest an average of $1,300 for labor and equipment. Installing multiple cameras gives you comprehensive coverage of vulnerable entry points and enhances overall property security.
