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!
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.
Kevin from Grasser Home Services was professional and a delight to meet. He did a great job installing several GFCI’s at my residence. When I need any other electrical work done, Grasser will be my go to!
Very professional and work was completed well and timely.
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.…
Paul G. was great. Extremely helpful, answered all questions, and was very knowledgeable. Was prompt, friendly, and overall great service. And left the house looking extremely clean. 5/5
Grasser was very accommodating. The electrician, Billy Lewis was friendly, knowledgeable and very neat and orderly.
We’ve been using Grasser for 20 years. Always great and honest service. Every employee is too notch
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…
I had a short list of things that I wanted done by a professional: Kevin from Grasser was exactly that. We talked about lighting options for the basement and garage. Kevin put together a couple quotes which included updates to outlets, installing a new doorbell, and correct labels on the basement breakers. By…
Grasser has been the easiest company to work with and they were well informed about any questions we had. They sent Brendan and Paul to install Alumicons in our outlets and switches for aluminum wire remediation in our new home. The guys were so respectful of our home and our time. Also, they got the job done while…
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.
Brendan is amazing! We had electrical to our pool pump go bad and after an entire day of me replacing outlets and breakers, my problem still was present. It was time for an electrician. Brendan was our tech and he was incredibly nice and knowledgeable. He was up front with the cost, which I greatly appreciated and…
Brendan and Jake were both Excellent from start to finish. In fact, the entire process from estimate to job completion was a good experience.
I had 2 fulls days off work done at my house by Grasser Electric. They upgraded my panel to 200 amps, pus installed many cans lights, outlets, and smart switches. I'm very happy with the work and professionalism of the team.
Grasser Electric did a phenomenal job installing track lighting in my jewelry store. The precision of their work is truly unmatched—it completely elevated the ambiance of the space. They are professional, courteous, and easy to work with. During our build-out, we ran into issues caused by the alarm company’s…
