"Thomas M was an excellent technician and did great work fixing all the basement windows around the house. These windows are difficult to find a replacement but he was able to repair and repaint them. The other technician was Pablo He worked on caulking all the windows around the house and he did some filling work on the garage sliding doors You did a good job, but Pablo left his trash around and didn’t pick up after himself so Thomas M and I did that on the third day. It took three days total, but it was two men for two days and one man for a 3/4 of a day actually. Although I’ll probably get charged for a full day, since it went past noon. The labor portion is the most expensive and a little higher than I initially anticipated. So, I was hoping for a quicker turnaround, but overall quality work was completed. I would highly recommend Thomas M as a technician to do future work. He’s very knowledgeable, friendly and does a great job. I would hire again but include more details in the contract language."

FAQs for alarm or security system installation projects in Essex, MD

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.
