Leave Us A Review

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!

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.

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.
