"Steve Cavanee Electric installed a power transfer unit at my house to transfer power from the grid to generator power. They did excellent work, showed on time and did the installation at a fair and reasonable price. They provided follow-up communication with directions as well. I will be using them again as the need arises."

"Very happy with the work completed by Bill (owner), Josh and Pat. Bill always responds promptly to text and calls and explains things clearly. Provided free quote and visited the house to confirm quote. Josh and Pat arrived on time and worked neatly. Josh was able to avoid trenching thru the ceiling even though attic space was limited. They even put back closet shelf that had to be removed to access attic. Josh and Pat even came by another day to help install a remote that I did not have on the day of installation."

"The folks a M&ES CONSTRUCTION ENGINEERING INC. Did a great job with my project. They renovated my garage, they drywalled and painted it, also gave me a beautiful epoxy floor thats easy to clean and a treat for the eyes. I also had them remove my old brick gas fireplace and build a tile faced electric fireplace with an insert for my Television. My TV fits perfectly and it looks amazing. Workmanship is top notch, they are transparent, punctual, and very communicative. Truly the best contractors I’ve worked with."
