I recently worked with Kolji Bros for electrical work in my new home, and I couldn’t be happier with the experience. Thomas was professional, thorough, and an excellent communicator — he explained any issues in detail and provided practical solutions. He also made sure to follow up on any incomplete work to ensure everything was finished properly. The pricing was very reasonable, and the quality of work was of a very high standard. I’d highly recommend Kolji Bros for any electrical project, big or small, in your home.
