What Our Customers Have to Say

Leave Us A Review

Stan O.

I had an exceptional esperience with Klos Concepts. FIrst, Karl personally came to my home to evaluate my needs and his insiights and recommendations were realy helpful. I needed a re-installation and upgrade to my EV charging port and his team handled everything in the fastest and most effective possible manner. They dealt with minor challenges in the wall placement and existing intrastructure with care and consideration and the end result is perfect. They worked with me to schedule the installation job as soon as I received the charging device from Best Buy and he whole service from top to bottom was smooth.

Susanne G.

Customer service beyond compare, from booking the appointment to the follow-up after the job is done. They deal in electrical solutions and peace of mind. The team works diligently, they’re on time, efficient, professional, skilled, and they leave no trace that they were here other than a job well done. Highly, highly recommend.

Klos concepts has assisted me and my family on 3 seperate projects. Always timely, efficient, reliable and easy to work with.

The team did a great job for me with a minor repair needed for an old fluorescent light fixture. They were fast, responsive, competitively priced and very pleasant to work with. Thank you!

John B

Robyn and Sean from Klos Concepts were amazing! They handled outlet and switch installations, repaired our potlights, and even fixed a tricky chandelier in our 120-year-old house. They were professional, friendly, and clearly skilled at working with older homes. Everything works perfectly now, and they left the space spotless. We’re so impressed and would highly recommend Robyn, Sean, and the Klos Concepts Team.

Gerald C

Best decision we made. We just finished a complete kitchen renovation in our 100+ year old house and of all the trades involved Klos was the best. From start to finish the team was amazing. Excellent communications, on-time and on-budget! Helpful and informative at every step. New potlights, chandelier, under counter lighting and all the new plugs and circuits to totally modernize the electrical and improved the functionality of the space. The results were spectacular. Special thanks to Andrew, Ryan and Kristin: the inhouse team. On site electricians — Jeff and Min were amazing. They turned a spaghetti mess of wiring into a modern, and safe system.

Steven M.

Klos Concepts provided the electrical services for our recent renovation, from the original tear-out “make safe” work to the installation of new wiring, outlets, smart lighting, and data networking. Three different electricians in all — and they were all true professionals in both their work and their personal deportment. We’d recommend Klos to the closest of family and friends — and that’s a rare thing for us.

David N.
