Stephenson Home Improvement has been providing new and replacement, high-quality, maintenance-free vinyl windows to homes and businesses in Strathroy and the surrounding area since 1959. We offer several styles and colours to fit your project’s needs.
We supply and install North Star Windows, a Canadian manufacturer offering a wide range of vinyl windows. Their products come in several styles, colours and glass options, with great warranty coverage.

Explore the nine window styles we offer.

Vinyl casement windows open and close easily with the turn of a handle and offer an unobstructed view. Installed on their own or paired with other windows, casement windows complement any room.

Our single-hung vinyl windows offer the traditional look of a hung window while providing improved security, lower maintenance and increased energy efficiency. The operating sash also tilts in for easy cleaning.

Double-hung windows have two movable sashes, allowing you to open the window from the top or bottom. They look traditional, have good ventilation and the tilt-in sashes make it easier to clean.

Sliding windows open horizontally and are easy to use. They're a good option for wider openings, offering plenty of natural light and a clear outside view.

Vinyl awning windows are often placed above or below other windows, or above doors for increased ventilation and light. Hinged at the top, awning windows open outward with the turn of a handle.

Bow windows extend outward from your home, creating additional space inside and allowing more natural light into the room. Typically made up of four or five window sections, they're a great option for living rooms and other spaces where you want a wider view.

Vinyl bay windows add space to a home’s exterior and improve natural light in the interior spaces. Projecting outward from a wall at 30 or 45 degree angles, bay windows create a cozy alcove using any combination of picture, casement, or hung windows.

Custom windows are available in a variety of shapes and sizes to suit your home's design and existing openings.

Picture windows are a simple, versatile option that lets in plenty of natural light and provides an unobstructed view outside. Since they don't open, they also offer excellent energy efficiency.

We offer a range of glass packages to improve comfort, efficiency and privacy.
Thermal performance is improved by replacing the air between the panes of a window with Argon gas, an inert, slow-moving gas. Argon gas helps prevent heat loss to improve energy efficiency.
Triple-glazed windows use three panes of glass to dramatically reduce condensation and thermal transfer while insulating as much as 60% better than double-glazed windows. North Star’s optional triple-glazed windows offer incredible energy efficiency.
Krypton gas is an inert, slow-moving gas that improves thermal performance. Denser than Argon, Krypton gas does an excellent job of preventing heat loss. Krypton gas filled windows are available exclusively in North Star triple-glazed windows.
Glass that features a bronze tint can cut down on the amount of glare and heat entering a building.
LoE 366 is recommended when cooling costs outweigh heating costs, or where summer discomfort from heat build-up is a concern. It has a lower Solar Heat Gain Coefficient (SHGC) and a very high reflection rate in order to minimize radiant outside heat, preventing heat gain in the summer while still retaining radiant heat in the winter. LoE 366 is the best glass for areas of direct sunlight.
LOF – Pilkington Energy Advantage Low-E is the best glass for most applications in a northern climate. It has a very high retention rate of the heat in your home in winter and prevents heat gain from outside in summer. Energy Advantage Glass has a higher Solar Heat Gain Coefficient (SHGC) than Low-E glass designed for more southern climates, providing free winter heat for your home. Since as much as 95% of your energy expense for heating and cooling combined is for heating, this glass is more cost effective than glass without a high SHGC.
A unique treatment that allows the glass to break down organic dirt that collects on the surface. Dirt washes away with the next rain, leaving no streaks or spots. Pilkington Activ™ Self-Cleaning Glass is available in every North Star window.
Tempered glass offers added strength that is up to four times greater than conventional glass so that when shattered, it breaks into small pieces. It is required as safety glazing in patio doors, entrance doors, and side lights.
Obscure glass provides an effective shield without shutting out the sun. Obscure glass is particularly useful for bathrooms, basements or along walkways. North Star offers obscure glass in Rain, Glue Chip, Frosted and Acid Etch patterns.
