What our customers say about us
Known for reliability, efficiency, and precision, MJ Ontario Constructions is Windsor’s trusted partner for commercial, industrial, and luxury residential projects
From the initial design consultation to the final installation, their professionalism and attention to detail were exceptional. Manjeet is extremely humble and approachable, and he offered creative suggestions while always keeping our budget in mind. The quality of workmanship is excellent, and everything looks amazing.
I highly recommend MJ Ontario Constructions Inc to anyone looking for a seamless and high-quality construction and renovation work.
What stood out the most was his ability to listen to our needs, keep our budget in mind and suggest only what was absolutely required without cutting any corners. This honesty and reliability made the entire process stress-free. Manjeet also has a strong knowledge of the Ontario Building Code, which proved invaluable. His expertise helped us save a significant amount of money by demonstrating relevant OBC guidelines to the city's building official, which avoided the need to remove bathroom walls.
We had pulled a permit for the basement ADU, and Manjeet took charge of scheduling inspections and worked seamlessly with the City of Windsor inspectors, ensuring that all inspections were passed without any issues. He interacted with the city several times regarding the permit, making sure that only the necessary work was done and that it was done correctly. He remained committed and focused until the very end, accommodating city inspection comments patiently until we received our occupancy permit.
Moreover, I have referred Manjeet to three of my friends, and each one of them has been just as happy with his work as I am. This consistency in delivering exceptional service speaks volumes about his professionalism and dedication. He also made sure to engage the right licensed trades for electrical, plumbing, and other critical work, ensuring everything was done to the highest standard.
A big shoutout to his crew as well, who were professional, skilled, and hardworking. They showed up on time, were respectful of our home, and contributed significantly to the success of the project.
Overall, I highly recommend Manjeet and his team at MJ Ontario Constructions for any construction project. Their professionalism, expertise, and dedication are unmatched. Thank you for making our basement ADU project a success!
I cannot speak highly enough of the exceptional service and craftsmanship provided by this construction company. From start to finish, their team exhibited professionalism, expertise, and attention to detail that surpassed all expectations. Our project was completed on time, within budget, and the results are simply outstanding. I wholeheartedly recommend them to anyone seeking top-notch construction services.
Thanks again from Amanda and Bradley🙏🏼
