We had smoke detectors and a pull alarm installed and couldn’t be happier with the service. Jr and his team were professional, punctual, and extremely knowledgeable about fire safety requirements. Everything was installed cleanly and efficiently, and he made sure to test all the equipment before leaving to ensure it was working properly. He also took the time to explain how everything works and answered all of our questions, which we really appreciated. The whole process was smooth and stress-free. I would highly recommend him to anyone needing electrical or fire safety work done!

We had Jr and his team install an EV outlet in our garage, and it was a job very well done. They were professional, friendly, and took the time to explain our options. ?Our installation required upgrading a circuit breaker and running heavier gauge (AWG) cables to handle the power load safely. They did a great job navigating our home’s limitations and helped us make the most informed decision for our setup. The final result is clean, professional, and works perfectly. Thanks for the great experience!
