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.

Service has been very professional and friendly. Andrew was very attentive to my EV charger needs and was very transparent about the work that would be needed. He made sure I was fully informed and made the process very seamless. Highly recommend
Nathan C.
I have been a client of Karl and Klos for many years. Karl and the team are always responsive. They do great work, leave the house clean and have reasonable rates. I recommend them for any size of a job.

Klos concepts has assisted me and my family on 3 seperate projects. Always timely, efficient, reliable and easy to work with. Prior to the job beginning, the scope of work was clearly communicated which avoided any surprises. Thank you to the Klos concepts team for your help. Looking forward to working with them again.
Ellen D.
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!

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.
Very pro and kind. Did a great job on my garage and fast. I would highly recommend Klos Concepts LTD
Molline G.
Everyone I dealt with at Klos has been beyond helpful, professional and accommodating. My questions were always responded to and I never felt I was overstepping the bounds by asking for more clarity/details on such things as the extent of the work being quoted or project invoicing. Finding good suppliers is important and Klos Concepts is definitely one of those reliable companies to call upon when needed. They have been a pleasure to work with at my cottage and I will certainly call upon them again for my electrical needs in the city.
