Absolutely the best electrician I’ve worked with. Professional, knowledgeable, and very reliable. The work was done safely, efficiently, and exactly as promised. They took the time to explain everything clearly and made sure the job was done right the first time. Fair pricing, great communication, and top-quality workmanship. I highly recommend them to anyone looking for an honest and skilled electrician.
Can’t recommend Denisco enough, came out for an emergency after hours call for us to make sure we were okay and had what we needed. Honest and fairly priced. They did a great job installing our home electric car charger and it has made life so much easier.
Professional, responsive, and great workmanship. Trevor and Dillan did an excellent job, worked efficiently, and cleaned up thoroughly when they were done. Communication throughout the process was clear and easy with the owner TJ. I’d absolutely request this crew again for future projects. Highly recommend.
Denisco Electric was outstanding from start to finish. Their team was prompt, professional, and clearly knowledgeable, taking the time to explain what needed to be done and then completing the work efficiently and safely. They arrived when they said they would, cleaned up thoroughly, and the quality of the workmanship shows they take real pride in what they do. It is great to work with a fully licensed, insured local company that genuinely focuses on customer service and getting the job done right. I will definitely be calling them for future electrical projects and highly recommend them to anyone looking for a reliable electrician in the Manchester/Concord area.
Is 2025 and I've been using mr TJ and his company since 2018. He's helping me updating my electric panel because the summers are getting harder and I need more window AC. Thank you so much for great work as always. Also I really appreciate you installing the 5 head mini split by Samsung at a single-family home
