We recently used Klos Concepts to correct a number of electrical problems in our home. They were wonderful to work with. Prompt, polite, and excellent in the work done. I highly recommend them for any electrical needs.

Great work, very responsive, friendly and professional, would use Klos again without question.

Klos concepts executed flawlessly from start to finish. Karl provided insightful and constructive input on how to achieve desired results. His team executed quickly and was very professional. Definitely recommend this company.

Klos did all the electrical work on our new house. Approach, execution, and follow up all of the highest caliber. The electricians engaged in the work were professional, knowledgeable and personable. Excellent work and outcome.

Great customer service, very responsive and timely — we were in a bind with no heat due to breaker failure on rooftop unit. Klos was there with proper parts & technician within 24 hours, thankfully.

Klos is my go-to team for electrical needs big or small. I love working with Robyn — she’s a dedicated professional.

The team at Klos was very efficient and professional from start to finish for the addition of an outlet in my kitchen.

We had a wired-in smoke detector go rogue and activate at all hours of the night. We contacted Klos Concepts and were so impressed by the level of service! Andrew set up an appointment, and kept us informed at every stage of the process. Tom arrived when he said he would and fixed the problem in short order. Everyone we dealt with was professional, friendly, and communicated what was going on. 5 stars for sure!

Fantastic experience from start to finish. When quoting, the team gave lots of options and suggestions for repairs and possible upgrades. During work, the team took lots of time to throughly explain how everything was being done, and gave an excellent breakdown of potential options when roadblocks occurred. Everyone worked flexibly with our schedule and was kind, courteous, friendly, and very responsive. All the work was completed on time and on budget with an extremely high level of attention to detail. Very pleased with everything and would highly recommend Klos to everyone!

The only electrical team and company I trust in the city of Toronto, Province of Ontario and the Country. You hear so many stories of trades going wrong — not with Karl and his team — you are in amazing hands, the job is done right, nothing to worry about and reasonable. Don’t look anywhere else — call them for all of your electrical needs!
