EXCELLENT Based on 519 reviews Posted on Google Cubby’s Reviews Had my breaker replaced same day as request for service. they were in and out quickly, and the amount due was very fair. I am going to set up a future appointment to have the complete electrical box replaced. Jordan communicated effectively and efficiently. Update 10/15/2026: Travis from LEHMANN electrical and design completed installing 4 gfci outlets and installed a CSST bonding for my gas line. He communicated throughout the process and did outstanding work. Do yourself a favor and contact LEHMANN if you need any electrical work completed they’re honest, their pricing is fair,and they always give you an estimate before they start work.Posted on Google Linda Sumwalt 16 year old solar panel removal from a barn roof.Posted on Google Verneesha Banks The guys from Lehman were great! They were very knowledgeable and informative. Answered my questions and went Above and Beyond to get things done.!Posted on Google Sally Shoemaker Great workers!Posted on Google Alicia Allison Travis did a great job, was VERY knowledgeable and kind, answered all my questions and more. Will be using LED again. Really like that they don't charge for estimates. Fair pricingPosted on Google Chris Cullen Fantastic service and communication. Highly recommend!Posted on Google Ed Chaltry We worked with Travis. From the moment he came out to give the estimate, he was very professional and able to answer our questions and provide the detail we needed to move forward. The installation itself was quick and of high-quality. I highly recommend Lehmann. Thank you!Posted on Google Renee Schultz Andy and Joe were so kind and professional. Andy offered fair pricing, and tried to repair my electrical issue using the most cost-effective solution. Would highly recommend Lehmann Electrical and Design!Posted on Google Sandy S I’d like to highly recommend Lehmann Electrical and Design. Recently my kitchen lost all power due to an overheating outlet. After calling several companies who were scheduling a week out for appointments, I called Lehmann and they came out the next day. Not only were their technicians, Alex and Travis, a pleasure to work with, they didn’t come in with a standard, by the book, approach. They thoughtfully considered and explained the options for fixing the problem, with safety being the number one priority. Lehmann will be my only choice for any future electrical needs.Posted on Google Krista Had a panel upgrade, fan installation, and some outlets relocated and added. I couldn’t be happier with Cavin and Team at Lehmann Electric! They were courteous, flexible, and knowledgeable; willing to answer any and all questions. Everything looks and works great!Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust. Only the greatest companies can get the verified badge who has a review score above 4.5, based on customer reviews over the past 12 months. Read more
