Windows & Exterior Doors


New windows and doors not only add style and comfort to your home, they’re also engineered to be energy efficient. Whether you're building new, renovating an older home or upgrading your cottage, windows and doors play an important role. Coordinated, updated doors and windows enhance curb appeal, energy efficiency and home security. Updating old single pane windows to current Energy Star windows can significantly reduce energy loss and utility bills. Coordinating window treatments, awning, shutters, detailed exterior doors and hardware create a modern, professionally finished look that adds pride and value to your home. There are so many great reasons to replace your old inefficient doors and windows. You can even match them to your roofing and siding colours.
