What Our Customers Have to Say

Leave Us A Review

Ruth P.

Impressive. Prompt response to service inquiry. Prompt appointment made. Highly professional scheduling team with clear communication on timing of visit. The electrician, Robin, was on time and did a great job of troubleshooting and repairing our issue. She even took notes in the event we needed to consider other options in the future. She explained what she did and why in plain language and could not have been more efficient or pleasant. Truly the experience with Klos was first class from start to finish. They even checked in to see how everything was working BEFORE they sent the very reasonable invoice. Definitely top of the list on our household service/repair list. We have our next door neighbour to thank for the recommendation.

Alexander C.

Best electrician’s. Team is super responsive on the back end too.

Really happy to have called these guys. Thank you

Lydia B.

The service and support provided from beginning to end was incredible. During the recent wind storm and heat wave our hydro meter post was damaged and needed a full replacement.…… during the heatwave!! The team that arrived first thing in the morning were awesome. They worked hours in the heat explaining things along the way. Our power was restored by mid day .…. A/C included. We would highly recommend Klos Concepts Ltd. Lydia

Jim T.

Klos Concepts did a good job tackling a knotty problem for us. A tree limb took down our power lines, breaking the insides of the meter base. The owner Karl Klos searched diligently for a replacement part, in order to save us some expense. This was unsuccessful because of the age of the equipment. Ultimately, a bunch of stuff had to be replaced, including a brand new meter base, but Karl worked closely with ESA to re-use as much of the existing installation as possible. They coördinated with Hydro for disconnection and reconnection of the power lines to minimize our time without power. The techs on site encountered a few issues, but solved them without a lot of drama. They were conscientious and efficient. The final installation is clean and does not affect the appearance of the house. They had gotten pre-approval from ESA for their work, and so once Hydro reconnected us, we had full power. We highly recommend Klos Concepts for electrical work.

Sarah X.

Truly 5* service!
Klos Concepts was quick to respond to my inquiry, got 2 electricians over to my house within a few hours, and had the issue fixed shortly thereafter.
Information (including prices) was sent to me ahead of time, so there were no surprises.
The problem we thought was the culprit was actually not, but Connor and Noah worked diligently and were able to figure out the issue and get it fixed. They were kind, professional, and respectful!
Thank you so much for your help. Klos Concepts will be our go-to for our electrical needs!

Great service! They were very professional and responsive. Jeff and Noah were prepared and very knowledgeable. They were neat and left everything clean.
