Pieux Vissés Rousseau is a screw pile contractor based at 630 Rue Favre in La Prairie, Quebec, on Montreal's South Shore. Its website describes galvanized steel screw piles and lists a Quebec construction license (RBQ) number.
The company installs screw piles for sheds, patios, stabilization work, sunrooms, foundations, cottages and additions, and it also offers mini-excavation. The site states that its piles carry a lifetime guarantee and that quotes are free. Screw piles go in without pouring concrete, which suits small outbuildings and light structures as well as additions where a conventional footing would be disruptive.
The website is in French and shows weekday hours from 7:00 to 17:00 and Saturday mornings. Homeowners in La Prairie and the surrounding South Shore area can call 514-213-2365 for a free quote. Before hiring, ask what pile size and shaft diameter will be used, how the installer confirms depth and capacity, what the guarantee covers in writing, and whether an engineer's letter is needed for your permit.
