These guys are here to serve you, not sell you. They built their business off making genuine relationships. They continuously take care of our family no matter how small or big the job is. You will not be disappointed by choosing Grandslam.

In 2017 we had Grand Slam AV and Security install a server and Control 4 system. It controls lighting inside and out, 5 TVs in 4 bedrooms and family room, 2 separate HVAC systems, security cameras, door locks, monitored fire, door and window alarm system and wireless wifi access points covering entire house. All this from a remote control or iPhone/iPad app. I called last week for a service call to repair a light switch and install 2 Apple TVs. Jerry and his crew showed up as scheduled first thing Tuesday morning. They got the light repaired and Apple TVs installed and showed us how to operate a few features we were not aware of. These people are true professionals in every sense of the word.

The Grand Slam team has been great throughout the install process and helping me troubleshoot and resolve some issues. My install consisted of three cameras and a video doorbell, all installed quickly and professionally. The technicians helped guide me through the apps and showed me how to access my cameras. The customer care is top notch -extremely responsive and very accommodating (thank you, David!). The technicians are always very friendly and helpful as well. I would recommend Grand Slam for any home security needs.

If any review will be the one potential customers will make their decision on, let this be it. We shopped for weeks, at least a dozen different install services around Houston, including the company that pre-wired our new construction home, and we just weren't happy with the quotes we were provided. I just happened to see Grand Slam's service
van driving while I was on my way to work one morning; it was like a sign from above *cue angelic, ethereal music* and I cannot say enough great things about these guys. They came out, got the job done exactly how we wanted it, and even made some suggestions to help us get the most out of our security system. We had some technical issues with one of the cameras and they came out asap to fix it. Their customer service is unparalleled; they are responsive, professional, and I would recommend them to any and everyone looking for AV/Security set up. Stop searching and call Grand Slam now!

These guys are the real deal!
They will work with you , very respectful, keep to time and even when I had to call them back to fix something, they responded on time. I would recommend them to everyone.
Thanks John, Jared, David and Edgar for hooking up my 133" media room and the internet networking.
