Mike Came out to our home in St Ann. He did an amazing job and finished the work the same day as the quote. Phenomenal customer service, knowledge and execution.
Brendan showed up on time, had clear communication and set expectations well, explained pricing in detail, and completed the work in a timely manner. He went above and beyond!
I had an estimate done, then within the week they were out to do the job. They sent Billy and Phil out today to update my electrical wiring. Both were great!! They were friendly and knowledgeable. They went right to work and answered any questions I had. I highly recommend Grasser! Thanks guys!
Had a great first meeting with Mike today. Can wait to get the project going. Finished project with Mike everything was great.
My technician Mike was friendly, knowledgeable and very thorough. He went over and beyond in services. He addressed items of concern that initiated the service tequest but also explained a few additional items that were non related and helped troubleshoot. He was on time and spent the needed amount of time without rushing.
We had a problem with our dryer if it was beyond half full, it would trip the 30 amp breaker and have to be reset often multiple times per day. Mike came out and showed me the thermal scans of it heating up and failing, so we opted to replace all of our aluminum wiring with copper from new breakers to the wall…
Huge thanks to IBEW Local 1 for recommending Grasser Electric. From the initial proposal all the way through the final walk-through, working with them was seamless. Billy and Sean did a top-shelf job upgrading our main panel, adding a circuit for our mini-split project, along with a dedicated garage circuit.…
Mike was courteous and professional. The work that was performed and pricing for the service was fully explained upfront beforehand. He got the job done quickly and am pleased with the outcome. I would highly recommends Mike for all electrical needs.
Grasser was very accommodating. The electrician, Billy Lewis was friendly, knowledgeable and very neat and orderly.
Grasser was the 3rd company I called about an issue with our breaker box. They were the only company that didn’t charge us a fee to come look at it. We had two companies quote to replace (and combine) our breaker boxes. Grasser was significantly cheaper. From the staff in the office to the electrician in the field…
Paul G was our electrician, he was kind and helpful and gave us some suggestions for our basement lighting. We had 8 new large lights installed, plus a surge protector on our circuit breaker box, two new light switches and cleaned up and took down old wiring/lights that were not to code. I would highly recommend him…
Sean did a great job helping me determine the best way to power my camper by using a larger breaker. He also installed a new GFI plug for our spare refrigerator in the garage.
Sean and Kevin were fantastic. The completed work included multiple outlets added to the basement, as well as a new light fixture, which had a dry walled ceiling. They completed all the work without a trace of mess left behind. Would definitely use again for other work.
Adding EV charging and surge protector was fast and efficient. Billy was friendly and professional. He offered solutions to what was needed and answered all of my questions. This was truly a 5 star experience! Billy, keep being awesome!!
Update: Sean and Jordan did a significant amount of work and were great. They communicated well and asked if we had questions throughout. The work was top notch. We would continue to recommend them. Original Post: We had two high ceiling light fixtures replaced as well as a wireless light switch outside our a…
From the moment we called Grasser the experience was five stars!! Gabby & Lisa in the office helped set up our estimate & followed up afterwards. Candy thoroughly explained financing available. Paul G came out & gave us a thorough explanation & estimate of everything! On the day of service Paul G and Jordan F got…
Marc and the Grasser Electric team are great to work with. Communication and quality of work is top notch!
Jordan did an excellent job repairing electrical wiring, installing two ceiling fans and installing a new doorbell system. Jordan was prompt, very knowledgeable, very informative, friendly, and answered any questions that I had. I was very pleased with the service I received from Grasser.
The Jul 4th storm caused water leaking into our electrical panel. I called Grasser Monday and Tuesday Marc H. arrived to assess the problem. Water in the panel was the major concern but Marc took the time to review other electrical notables of our 50 year old electrical. It was decided the panel needed to be…
Marc Horton was professional and respectful. Walk through each step in order to solve our issue.
Billy did an amazing job getting our home ready to sell. He installed can lights and work to trouble shoot and repair some issues. He was polite, professional and knowledgeable. We've enjoyed working with Billy and Grasser Electric. Would highly recommend him and his services!
Kevin installed a new light switch and hooked up electrical for the installation of a shower light
Excellent service from Paul G. Very nice and super efficient. Explained everything in a simple way so us non electricians understand. Very accommodating of my crazy uncle and his mess. Second time using you guys. Will definitely call again in the future as long as we get Paul.
Jordan did an excellent job installing a new sub panel and repairing a broken line in the wall. Will definitely use this companies services again. They are responsibly priced and stand behind their work.
The entire process was fantastic, from initial contact with the Grasser office to job completion. Sean was assigned to perform my estimate. After we discussed my desire of the job, Sean walked me through a detailed evaluation, explanation and estimate of the job, along with options. Sean performed the tasks quickly…
We had Brendan out for electrical work in our garage. He was prompt, fast, and did exactly what we agreed to. The best part was that when he was done, everything was restored to new. We can’t recommend Brendan or Grasser Electric enough and will definitely reach out to them again for our electrical needs.
Billy did a great job.
Marc was knowledgeable and friendly.
I have used Grasser Electric for years for all of our electrical needs at several large multifamily apartment complexes and have zero complaints or issues. John Baumann is great to work with and the staff is very well trained and they have a great support team behind them. You will save money in the long run by using them, trust me.
Billy Lewis did a fantastic job putting a transfer switch for our generator. Very nice and professional!! I highly recommend Grasser Electric!!
Our technician Billy was great! He was patient while we explained our vision and more than helpful to give us his insight on the possibilities that we hadn't even thought about.
I lost power in half of my house. I called the after hour line and asked for someone to call me first thing in the morning. The sales manager called me and had Billy out there that day they detected. I needed a new panel and gave me a very fair price. They were able to replace it the following Monday including…
