"Jason handled the project expertly and delivered everything right on time. Before starting, he visited our home to assess the current system, quickly identified the issue, and presented us with two clear solutions. He took the time to answer all our questions thoroughly and patiently. The installation was completed in a single day, and Jason made sure both my spouse and I felt comfortable using the remotes and phone apps for our new system. There was quite a bit to learn, but Jason stayed with us as long as we needed, ensuring we were completely confident. The final price matched his original quote exactly, and we couldn’t be happier with both the outcome and our experience with Illumi-Tech. "

Home Security Systems questions, answered by experts

The average cost of a home security system is about $700, ranging from $280 to $1,150. Costs to consider include equipment, surveillance fees, and other additional features. Cost factors that determine your system’s price include the type of security system, materials, labor, activation fees, monthly fees, and permits. Additional features and upgrades may include:

  • Video surveillance monitoring: $40–$65 per month

  • Smart home locks: $150

  • Smart home lighting: $15–$90

  • Smart smoke, fire, and carbon monoxide alarms: $35–$100

  • Smart thermostat: $130–$500

Yes, driveway gates can help secure your home by deterring burglars from accessing your property. Climbing a gate slows down burglars while also attracting attention to your gate. If you live further down your property and want to increase security, you can also install a gate security camera that connects to your gate and monitors the area for suspicious activity.

Not all security systems are equal, so familiarize yourself with the many features available and any associated costs. Decide on a wireless or wired system and look at monthly subscription fees to access the service. Finally, read plenty of reviews to check out the efficacy of your intended security system.

If you're wondering what you should do with your old security alarm system after installing a new one, one option is to properly dispose of it at an electronics collection facility. Otherwise, if your old system is still in good shape, you can also donate it for someone else to use in their home.

You'll likely need more than great home staging to sell your home. Now is a great time to get to work on the curb appeal of your home . Hire local exterior painters and landscapers to coat the exterior of your home and bring it new life with some sprucing up.
