"I contacted Colwell Electric because lightning struck my home and damaged quite a few outlets and light fixtures. Mike D. took great care of me. He was helpful and answered all my questions. His team was excellent - did a great job installing and replacing light fixtures and outlets. I am very pleased with their work and professionalism. I would highly recommend them to anyone."

"Called for an estimate on a chandelier replacement installation and a added outdoor electric socket. Casey came and gave me a reasonable price. I’m very happy with how professional and friendly he is. Great quality work. Will definitely be using Colwell electric in the future."

"As Realtors, we are always looking to add value to our clients. I’m excited about the new product Colwell is offering to monitor the electric connections in my home. It’s monitored 24/7 and if there’s ever a short, or over-heated wires, I get an alert. My home is 18 years old. I’ve not had any alerts, but I run ceiling fans 24/7 and have for 18 years. I have worried about shorts.....not anymore. What a great service you offer!!!"

"Colwell Electric showed up on time and completed the repair that was needed very professionally. When there was a minor error on the invoice, they took full responsibility and waved the charges. You just don't find that anymore."
- Don Sanders
"I contacted Colwell Electric for an estimate on repairing an electric pole that was taken down during a storm and adding electricity to a work shed. Mike and his crew displayed quality work, great value, and completed the project in the initial deadline. I will certainly use them again in the future. Thank you"
