Company Background
About Timberline Portes et Fenêtres
Timberline Portes et Fenêtres runs from 946 rue Bégin in Saint-Laurent and describes itself as a generational family team. Founder Frank Luongo brought more than 30 years of hands-on experience to the business, and his son and son-in-law later joined him. The company says it stays involved from the first product selection to the final installation rather than simply supplying units.
Heritage homes are called a core part of the work. Timberline replaces windows, entry doors and patio doors, and the services page describes careful removal of original units, a structural check of each opening and finishing that respects the home's character. Products span PVC, hybrid, wood and European tilt-and-turn systems, and the site shows Andersen among its manufacturers. It also says it helps homeowners navigate the Rénoclimat program for available grants.
The website lists RBQ licence 5729-2054-01 and describes ENERGY STAR certified products with up to 20 years of warranty, backed by manufacturer warranties. It says it serves the West Island, Laval, Westmount and surrounding areas of Greater Montreal. Posted hours are Monday to Friday, 9 a.m. to 4 p.m., with showroom visits by appointment only, and quotes are free.
Timberline has 5.0 stars from 112 Google reviews, read November 3, 2026. Check the Google listing for recent comments on scheduling and finishing work.
Timberline suits owners of older stone, brick and heritage houses who want a small family crew and are comfortable with a smaller company. It suits less well anyone who wants a large showroom to walk into or weekend hours. Before booking, ask for a written quote that names the product and series, ask for the manufacturer warranty documents, confirm the RBQ licence on the Régie du bâtiment du Québec lookup, and ask how long the install of a full set of windows will take.
