20-YEAR WARRANTY

LMO installation stands out considerably from the competition by offering you a turnkey installation backed by a 20-year labour warranty. The quality of materials required for our installations, such as urethane foam insulation and exterior caulking, is often neglected by companies, which greatly reduces the efficiency of the window. By combining the best components on the market such as Hilti brand insulation and commercial grade caulking, the energy efficiency of your opening is maximized and has a much higher life expectancy. For the interior finish, we cover the perimeter of the window with adhesive tape and then install (nail + glue) the interior mouldings. Our mouldings are touched up with paint at the end of the installation. And finally, Michel of Laveur de vitres 4M, will make your windows shine 48 to 72 hours following the installation (the drying time recommended), making this a true a turnkey installation.

Our insulation is Hilti spray urethane foam, the only company to guarantee complete insulation up to -40°C. We then seal the perimeter of the window with quality adhesive tape before installing the mouldings.
