“I had an existing alarm system installed by another company, but their customer service was terrible and the contract was impossible to get out of. Sentinel not only helped me cancel my old contract, but they also took over my system, upgraded it, and lowered my monthly bill. Colton was honest, professional, and made everything super easy. It feels great to work with a local company that actually cares.”

“We just moved to Charleston from out of state and didn’t know who to trust with our home security. After reading reviews, we decided to go with Sentinel — and we’re so glad we did. They came out the next day, explained all our options, and set up a great system without pressuring us. It feels good knowing we’re supporting a local company that’s been protecting families for decades.”
