 Trustindex verifies that the original source of the review is Google. Amazing work.

I hired sdm contractors Underpinning to do underpinning for my basement and I am very impressed with their work. Dion and his team were professional, courteous, and efficient throughout the whole process.

They explained everything to me clearly and answered all my questions. They completed the job on time and on budget, and left the site clean and tidy. My basement is now 2' feet higher and is much more spacious and comfortable, and I am very happy with the results. I would highly recommend sdm contractors Underpinning to anyone looking for underpinning services in Toronto.

They are the best in the business!

 Trustindex verifies that the original source of the review is Google. Dusan and the Underpinners are perhaps the best contractors I have ever worked with.  They are responsive, knowledgable, timely, thorough, friendly and considerate.  They completed our underpinning on budget and in less time than expected.  The job site was always clean and tidy and every one of the tradespeople on site was friendly and courteous and treated my home as if it was their own. Dusan  and the crew demonstrated their in depth knowledge of the work required from start to finish.  I would recommend The Underpinners to every one of my clients and friends. Truly a world class company.

They completed the work on time and on budget, no surprises, even with the extreme heat they kept working and finished to stay on schedule.
