Leave Us A Review

Strickland Builds I.

We’ve worked with Klos Concepts on many projects over the years, both larger scale renovations and smaller jobs, and they are exceptional across the board. As a contractor and home builder, trust, reliability, attention to detail and competence are non negotiable, and they have always consistently delivered on all.
Everyone on their team is highly professional, knowledgeable, and efficient, with a clear commitment to doing things properly and safely. Everyone communicates well, stays organized, and get the job done right. On the rare occasion something needs to be adjusted or revisited, they’re quick to respond and always make it right without hesitation.
We also appreciate their diverse team of skilled men and women something both we and our clients appreciate.
An excellent company with an excellent team. We trust Klos Concepts completely and highly recommend them to anyone throughout the GTA.

Glen N.

I had an excellent experience with Klos Concepts when they were called in to troubleshoot some electrical issues at my property. From start to finish, the service was professional, efficient, and incredibly reassuring.

A special shout-out to Robyn for her exceptional work. She arrived exactly on time, was friendly and approachable, and demonstrated absolute electrical expertise. What really stood out was her ability to quickly get to the root of the problem, clearly explain what was happening, and provide sound, practical advice on next steps. It was obvious she knew exactly what she was doing and took real pride in her work.

Electrical issues can be stressful, but Klos Concepts inspires confidence. They are the kind of professionals you truly trust to do the job right the first time. I would not hesitate for a second to recommend them for any job that requires the very best in electrical work.

If you’re looking for skilled, reliable, and top-tier electricians — Klos Concepts is the team to call

N K.

We are very happy with the service we received from Klos Concepts. When we contacted them via their website form, Andrew and Kristen responded promptly and professionally. They were able to accommodate us quickly in their schedule. Their electrician Jeff arrived 10 minutes early (on a snow day, no less) for the appointment and he was excellent and knowledgeable. It has been great dealing with such a professional and friendly team that also communicates well. We will always use Klos Concepts from now on for any electrical issues and repairs.

Heeral S.

Karl and his team always do great work and are very reliable

Jordan G.

I needed a few things done in our loft (which already has a bit of tricky wiring) and Klos came in quickly and efficiently, diagnosed the problems, solved them all, did the work, cleaned up, and left timely. As a person with *some* trade experience myself, I can guarantee you these guys know what they’re doing. You’re in good hands!

Ada H.

Very thorough and professional. Great communication, before, during and after. I will defiantly be calling them in the future for any electrical work.

Leslieville B.

We had a last minute need for an electrician to help solve an electrical problem for a holiday lighting activation. Someone from Klos came out immediately (within an hour) and they quickly assessed and solved the problem. It took 30 minutes and the activation that we had struggled to figure out was solved. They were incredibly pleasant and easy to work with. Efficient and effective. Cannot recommend enough.

cheryl L.

I had an emergency electrical issue at my business and the response was incredibly fast.
Communication was clear and professional from start to finish. Robyn my technician was great.
Highly recommend.

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!
