My newly purchased home needed to be completely rewired. Thomas assessed both the house and detached garage, made good recommendations and gave a reasonable estimate for the extensive work required to bring the all the electrical up to code. Throughout the project Thomas demonstrated true professionalism, was always available to answer questions, and freely shared his extensive knowledge. Everything was completed within budget but more importantly I have full confidence that his work has made my home safe. Kolji Bros are great guys and I highly recommend them!

They did a great job upgrading the panel and hooking up our sauna. They were on time, well-mannered, and took the time to understand the customer's needs. He also provides clear explanations of options and recommendations without pressuring into unnecessary work.
