"Tom did a fabulous job with the whole house plug installation for my back up generator. He was quick and efficient and cleaned up well after the work. He explained how to use the plug and manual interlock and made sure everything worked before leaving. Quality job on all fronts. Pricing was fair and he was able to fit me in on short notice due to another job rescheduling. I will definitely contact him again should the need arise."

"These guys were prompt, professional, and their prices were very fair. Brandon Neustel came to our house and added a generator inverter switch in less than an hour. Could not be happier with the work."

"We needed a 240V (level 2) EV charger installed in our garage. Our contractor friend highly recommended Charles. Charles looked at our current electrical panel which is almost 40 years old and had no space to add new circuits. He recommended we replace the panel with a larger one and promptly provided an estimate. We also asked Charles to install a generator inlet connection and an interlock switch for the panel so that the EV battery can be used to provide backup power in case of a power outage. Once we approved the project, Charles gave us a time and duration and he got the job done on schedule. He came back again to rearrange some circuits in the panel so that the EV battery can provide power to the important functions in the house such as kitchen, refrigerator, furnace, den, etc. Overall, we are very pleased with the work done by Charles and we have no hesitation in recommending him."

"Great electrician. Found a simple solution that others didn't think of."

"As we wanted a ev charger installed, they went out of their way to get us the correct one. They were prompt in installation and courteous in all interactions, fair and reasonable pricing. Would use again for electrical needs."

"Ideal experience with this company! They contacted me and came out to make the bid the same day I contacted them. They were super flexible and worked to accommodate my schedule. I needed to wait until my EV charger arrived from the manufacturer. They came out the day after it arrived, installed the unit in under two hours, and it's been working flawlessly ever since. Don't let their name fool you--John's Waterproofing is expert at electrical work! I will use them again."

"The whole experience with 3 Mountains Plumbing was outstanding from Nicole at the office to Jon Marc and Peter, the plumbers. They originally scheduled me for an appointment 5 days out, but Nicole watched appointments carefully and moved my appointment to the same day I called. Jon Marc, the plumber, was very knowledgeable and professional. He gave me different options, which allowed me to decide what worked best for me. He even gave me a teacher discount. After installing my water heater at 8:00 p.m. at night, he discovered a manufacturing problem with the water heater. He called another plumber, Peter. Peter was going off shift and was at the office, but got another water heater and brought it to my house so Jon Marc could install it! I think other plumbers would have said that they needed to come back the next day, but Jon Marc stayed until 10:00 p.m. installing the water heater. I will never use another plumbing company because 3 Mountains is the best! Nicole, Peter and Jon Marc... Thank you!"
