Following the recent work completed in just a day and a half, I highly recommend EXCAVATION CHANTHIER for their professionalism, as well as the friendliness and attentiveness of the workers. Impeccable work! Thank you from the bottom of our hearts for giving us back our yard after removing a 45-year-old pool. Now, it's time to play.

Excavation Chanthier is a name to keep in mind. Impeccable work on the removal of our inground pool. Marc-André and Jérémie did an excellent job—true professionals. We are more than satisfied with the work done, not only for their punctuality but also for sticking to the quote and keeping their word.
We easily give this company 5 stars.
Thanks again for your work. Highly recommended.
