Once your home is equipped with our top-of-the-line system, it is connected to a network of ADT Monitoring Centers nationwide which deliver non-stop security monitoring 365 days a year. All of our installation technicians are internal employees, and not third-party contractors. You can count on your Security Advisor to take the time to set up your system properly, help you understand how the system works, and help make sure your home and family are thoroughly protected.

"I got signed up with adt recently to get professional monitoring for my home. I don’t think I will ever need to use it but I want to be prepared for a variety of possible emergencies. The following pieces of high tech equipment came with my package – two control panels, one siren box, six door sensors, four motion detectors, one smoke detector, one doorbell camera for the front, and one exterior camera for the backyard. Got a lot for a reasonable price. I suggest going with ADT because of all that they offer and their history."

When you move, you’re packing up more than just “stuff.” You’re packing everything that makes your house a home. Across town, the state, or the country - we’ll help you get it there safely.

"JK uses a virtual estimate to provide a quote. That's a trick! It's common that the price they quote is a lot lower than what you WILL HAVE to pay to get your stuff. The process was easy, but can say the estimate we received to move across the country was $5,000 higher than 2 large PODs to start. In the end, they ended up adding almost $8,000...b/c they quoted the incorrect weight to start, as well as charging for a smaller truck that we never requested. The moving company that did the physical part, wasn't JK, and they were hard, polite, and great workers! I reached out and begged JK to help with the major increase (added 65% more to the total...and that was NOT budgeted in whatsoever! After numerous requests for ANY $ help, we were told simply "No." I worked with the physical moving company and they offered to help with some of the expenses...JK, Nope, Nadda, & basically told me TOO D*** BAD! DON'T USE THEM FOR ANY QUOTES!"

For over 35 years, American Home Contractors has provided exterior household services and upgrades across Maryland, Washington DC, and Northern Virginia. American Home takes great pride in ensuring customer satisfaction and commits to delivering the highest quality of work when renovating any home.

"American Home Contractors and Hugo in particular were great to work with. We had multiple jobs done which required several trips and Hugo kept us informed and worked around several weather delays. He relocated and installed a new attic fan, hooked up the bathroom fan to a new roof vent, insulated a pipe in the attic, installed apron flashing on four windows, painted the flue vent, reconnected some lose siding and replaced three pieces of rotted trim and painted it. The work appears to be top notch and we appreciate the hard work and long hours Hugo put in! I would definitely recommend this company and most certainly Hugo to everyone. We also had American Home Contractors replace our gutters and install gutter guards. They did an excellent job with that as well."

FAQs for alarm or security system installation projects in Germantown, 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.
