Exceptional Service & Ongoing Support – Highly Recommend Kajk Constructors!

After interviewing four different solar installation companies, it was clear that Kajk Constructors stood out as the best choice. From our first interaction, their commitment to customer experience was evident—not just during the installation but, more importantly, after the project was completed.

The entire process was smooth, professional, and exactly as promised. The team adhered to the agreed-upon timeline and budget, ensuring there were no surprises along the way. Their customer service was truly exceptional, addressing all our questions and keeping us informed at every stage.

What really sets Kajk Constructors apart in our opinion is their attentive support and training. They took the time to educate us on how to monitor and optimize our system, ensuring we get the most out of our investment. The level of care they provide after installation is rare in any industry, and it gives us confidence knowing they are there when we need assistance.

If you're considering solar, I highly recommend this organization, Kajk Constructors delivers on their promises and goes above and beyond to ensure their customers are well-supported during and after the initial work is done.

We are thrilled with the installation of our 9kw solar system! Kajk’s team was always there to guide us through the entire project.
We also really love the look of the black panels on the roof ??
Top notch!!! Highly recommend ??

I hired Kajk Construction to design and install a hybrid solar system on my house. Their attention to detail and workmanship were outstanding. Having used the system for almost a year my hydro bills are basically nothing and soon I will be profiting from the money Hydro pays for having the system on the roof. The crew and owner are a pleasure to work with. If I ever move I will only consider Kajk for solar on my next house.

I've had an exceptional experience with Khaled and his team at Kajk. I had a 14kw system installed with a battery backup and car charger. The installation went smooth, everything was done on time and with high quality, and I was well informed and prepared for everything during the process.

I've had exceptional support over the year since it's been installed including ongoing troubleshooting and a battery replacement.

I highly recommend Kajk for your home solar needs.

After interviewing several contractors, we opted to have our project completed by Kajk. Khaled and his team spent the most time properly reviewing and explaining the system and made sure that all our questions. We ended up having 28 panels installed as well as the battery backup. They provided very good guidance, support and patience dealing with the grants as well as any post-install questions. The install was done on time, very efficiently, and we are very happy with the final result. The follow-ups and optimization after the fact have been great, with Jacob reaching out seasonally to make adjustments to the battery storage amounts and any other settings.
