What Our Customers Have to Say

Leave Us A Review

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.

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.

Dina Lee M.

Super impressed with Klos Concepts! They were fast, professional, and got the electrical work done exactly when we needed it. Everything was handled efficiently without cutting corners, and the team was friendly and respectful throughout. Highly recommend!

Kathy M.

We hard Klos Concepts do the electrical work for our new Duke’s Live Music venue upstairs at Duke’s in Port Carling. They were so helpful with product and design ideas, scheduled the work and communicated just exactly the right amount and we would recommend them to other to use in Muskoka!

Nicole F.

We have worked with Klos three times in the last year and every time they have been fantastic! They’re incredibly professional — both the staff in the office and the electricians they send out on site. The work has been great. Communication is smooth and efficient. They arrive on time and give a specific appointment time as opposed to a long window. They’re definitely our go-to electricians!

Tristan M

I had the pleasant experience of hiring Klos Concepts Ltd. They were accommodating to my schedule, and had quick communications. After speaking with the electricians they were able to identify my electrical issues and make the necessary repairs. They installed a lighting unit in a room without prior lights. Amazing work and very professional. Would recommend.

Morgan A.

Five Stars – Outstanding Service from Klos Concepts!

We recently hired Klos Concepts to help upgrade the lighting and entertainment setup in our condo, and we couldn’t be happier with the results. From start to finish, the team was professional, punctual, and incredibly skilled.

They installed potlights, dimmers, and pendant lights throughout our space, transforming the overall ambiance and making every room feel brighter and more modern. Their attention to detail really stood out — they made sure every fixture was perfectly aligned and thoughtfully placed.

In addition to the lighting work, they also mounted our flat-screen TVs with precision and care. Everything looks sleek and clean, with all the wiring neatly concealed. It’s clear they take pride in their work, and it shows in the final result.

Klos Concepts made the entire process smooth and stress-free. Communication was excellent, and they were respectful of our home at every step. We highly recommend them to anyone looking for high-quality electrical work. We’ll definitely be calling them again for future projects!
