“Having had ADT for approximately 30 years, I can confidently say that my experience with their service has been outstanding. The customer service is always excellent, and the technicians they send out are incredibly pleasant and knowledgeable. I've even explored other options, but honestly, I'm very happy with ADT and don't see the need for change.”

“I’ve remained with ADT over the last 20 years and they've upgraded my system to keep up with technological advancements. Each interaction with their customer service has been remarkable, offering an outstanding experience. Even when their representatives come for upgrades or installations, the process is seamless, with great support and guidance throughout. If asked for a recommendation, I'd certainly advise friends or family to go with ADT. They consistently provide top-notch service across all areas, including customer care and product offerings. My overall experience has been impressive, and I would rate them at the top of the scale.”

“We always had ADT growing up and it just happened that the townhouse that I moved into was using it as well. It's been a great experience and we've never had any hiccups. We have one of those digital keypads. The guy came out and he was nice and quick. He got everything done and explained everything. It was perfect. I only have one exit in my house and I feel very secure. ADT is reliable. I can do things on my phone, like arm and unarm the house.”

Houston, TX Service Area & Local Process
The ADT Houston branch provides professional installation of the ADT Smart Home System throughout Harris County and surrounding counties, including Fort Bend, Montgomery, Brazoria, and Galveston counties. Professional installation times in the Houston metro area varies with the technician configuring each device — the ADT Base, sensors, cameras, and the ADT+ app — based on the home's layout, entry points, and the homeowner's priorities.
Houston's proximity to the Gulf of Mexico makes hurricane preparedness a priority. The metro's flat terrain and extensive bayou system create recurring flood risk during tropical storms and heavy rainfall events. In the event of a power outage, the ADT Smart Home System includes backup battery power to help keep the system powered during a power outage. If internet service is disrupted, cellular backup may help keep the system connected to ADT monitoring, as long as you have an active ADT monitoring plan and cellular service is available. Water and temperature sensors are essential for Houston homes, where bayou overflow and flash flooding affect neighborhoods from Meyerland and Brays Bayou to areas along Buffalo Bayou and Cypress Creek. For homeowners in flood-prone zones, water sensors positioned near water heaters, sump pumps, and ground-floor entry points provide early notifications that can prevent significant damage.
