Real Reviews from Our Customers

“We have used Sentry Electric several times and have always been very pleased with the quality of work, professionalism and pricing. Most recently Steve came to our home to work on our daughter’s fairy bedroom installing some new lights and reworking outlets. The work was done quickly and cleanly and our daughter is over the moon with the results. We will be using Sentry Electric’s services for all our electrical needs in the future.”

- Cymon K.

“I had a relatively straightforward problem with my outdoor outlets not staying on and flipping their central GFCI switch often and then eventually just not coming back on. The guys who helped me (I believe it was Steven and Reagan, apologies if I’m misspelling the names) not only got things back up and running with a new GFCI switch, but explained to me why the strange wiring in my house was likely done the way it was, how I can keep the outlets from flipping that switch so much (hint: don’t have an extension cord plugged in outside year-round where water can get in it), why GFCI switches might fail constantly after being flipped enough times, and what I could do with the outlets themselves if I ever wanted to make a more permanent change to the way they are being flipped at a central point.”

- Robert W.

“I received terrific service today from Sentry Electric. Joshua and Wyatt were very courteous and professional. I had a dryer outlet and relay box with wiring that had gone south. They gave me an estimate, explained the work scope thoroughly and did an EXCELLENT job on the new installation!! They also completely cleaned up after the install which I appreciated. I would definitely recommend Sentry Electric and will use them again for my future needs.”

- Carol S.

“Vincent is always friendly and thorough, and I appreciate his willingness to answer our questions. Sentry has always treated us with the highest level of professionalism, and we certainly recommend their services.”
