"The project was top notch. Marty installed a flood light and switch and would definitely use again and refer to others. Price was very reasonable. They were easy to reach, responded quickly, and communication was great."

"Excellent experience, highly satisfied! Based on the 5 star reviews on Nextdoor, I called Just In Time Electrical to have some electrical issues fixed and new lighting added. Michael came out within a couple days to do an estimate and returned a couple days later to do the work. My home presented a few special challenges, but Michael and another technician, John, worked through them with patience and expertise, and they successfully completed all 3 projects with professionalism and to my specs. I am thrilled with the new living room recessed lighting, remote wall switch solution in another room, as well as the corrections made to my bathroom 3-way lighting. Thanks guys!"

"Precision installed my water heater two years ago. When I had my furnace serviced, the technician checked the pressure on the water heater and it was very high, a component had failed. A plumber from Precision came out and replaced the defective part since it was under warranty. He suspected that a water pressure regulator may have to be installed but when he checked the water pressure coming into the house, it was in the acceptable range. He could have just as easily told me I needed this and it would have cost me $600 but Jacob was an honest man. I am so impressed with his integrity. I will use them again in the future for sure. The replacement of the defective part didn't cost me anything. Thank you Precision for being an honest company."
