Recommended Customer Reviews

I live in an older house and had issues with an outlet occasionally burning out and shutting power off to a section of the house. I always try to support local businesses so I called and spoke with John who listened to my problem and was able to send Steve within a couple hours. Steve had a good idea of what was wrong and corrected the old wiring in all 8 outlets which were on the same circuit and replaced a burned out outlet in about 2 hours. Price was reasonable and I was happy to pay for high quality work. Will call on them again if needed.

John was very accommodating. Electricity went out in my neighborhood and when it returned, part of my house had no electricity. I called John and he was willing to help me out that same day. He informed me of his hourly rate up front which was reasonable and he showed up as promised. He is an excellent communicator and kept me informed. He completed the repair in timely and profession fashion. I plan on hiring him to replace my breaker and rewire my home. I was very pleased with John.

My contractor recommended JSA to replace a gable fan that broke. John returned my call very quickly. He made a coupe of recommendations on how to replace it and had someone out within a few days. They showed up on time to make the repairs and had an excellent model to replace the fan. They made sure I knew how to operate the fan. They are are the top of my list next time I need work.

John and Steve did a great job upgrading us to a 200 amp panel. They were easy to work with and made us feel comfortable in the context of the pandemic. Plus they're local! Can't get better than that. Highly recommend.

A great experience working with John. He goes above and beyond. Re-wired entire house, getting rid of all the old non and tube wiring. Highly recommend!

John and Steve were fantastic! I see why they have all 5 star reviews. They were prompt, polite, cleaned up after themselves and did a fantastic job installing cans in the living room, outside patio lights, backyard lights and even redid an old rickety plug in the garage because they noticed it wasn't functioning properly. They will now be our go-to electricians. Could not recommend more highly!

John and Steve were great! They fixed both electrical
and non-electrical issues for me. Very knowledgeable and honest. Thank you! Would highly recommend them.

We could not be happier with John Andrus. He worked very hard to get our electric panel installed. He was there when he said he would be and worked many hours to get our electricity back and working. He is very meticulous and checked everything to make sure all was in order. His assistant, Steve, was also very good at what he did. They were a great team. We would highly recommend him. Thank you John.

John and Steve were wonderful -- they did a number of projects, large and small, all over our house -- with great professionalism and workmanship.

John installed a 50 amp breaker, all required wiring and Tesla Wall Connector in our garage for a new electric vehicle. Was responsive, work was flawless and even followed up with me after the vehicle had arrived to make sure everything was going well. Finally (and he did not need to do it) his team pointed out a water pipe leak in the crawl space of my house that if it went unfixed could have been a real probably for my family. Thanks to his team for a great job - very high attention to quality and met schedule and budget!
