What Our Customers Have to Say 

Leave Us A Review
Carolyn C.
I’m really lucky to know Karl, and he did an amazing job today. He helped me with an electrical issue at my home that had plagued me for almost five years. He was incredibly professional and handled the issue like the expert he is.
Kira von R.
This is our second time using Klos Concepts for electrical work at our unit. They are always punctual and did a great job addressing the issues we had in a timely manner. Jeff was great and answered all of our questions. We highly recommend!
Benoit J.
Klos did my entire house in 2019, and I have always used them since whenever I needed a new outlet. They are not cheap, but this is a case where you actually get what you pay for. Always effective, timely, good results.
Stefie M.
Excellent company! Efficient, professional, with excellent customer service. The electricians were always on time, handled the tasks expertly, and everything was done extremely well, and no dust spect to speak of after they left. Highly recommended!
Richard G.
We have an older renovated house in Riverdale.We had wiring problems in the kitchen overhead light and in the external security light.

We called Klos, who we had used before, on other electrical matters and they were able to send someone the next day. The electrician was able to identify the problems and to resolve the issues on site in an hour.

We were very satisfied with the service and would use Klos again in the future.
NADIA G.
I had the opportunity to once again use Klos Concepts for a repair. As always, they were responsive, took extra care and completed the repair. They are dependable and trustworthy and are my ‘go to’ for all my electrical repairs. You are always in good hands with Klos!
Karen H.
Klos Concepts has done work for me over the past several years. I’ve always been happy with their professionalism, courtesy and trustworthiness. I look forward to using Klos Concepts for future projects and would definitely recommend them to family and friends.
Adele M.
I’m very happy with the work we had done! The whole experience was great. They were communicative, on time, knowledgeable, and cleaned up afterwards. I highly recommend!
Michael H.
We hired Klos Concepts Ltd. to install a light in our entry hall. Normally this is a relatively simple procedure; however, our house was built in 1922, and installing the light required the removal of a cast iron bar and box that were part of the original knob & tube system. This was no easy job, and we were told that it may not be possible to complete without damage to the surrounding ceiling. From what I could hear from the comfort of a Laz-Z-Boy upstairs, removing that ancient box and part of the bar it was attached to required several cutting tools, both electric and manua,l and a lot of meticulous and, I would guess, frustrating work. When the light was installed, the ceiling was fully intact, no damage was done, and the dust and iron filings this job would create were nowhere to be seen or found. So, if you need electrical work done or your home, go with the best, the pros: hire Klos Concepts Ltd.
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.
