Alside Windows

Professional Home Improvement is a certified installer for Alside windows.

Whether you are remodeling, renovating or building a new home, Alside vinyl windows deliver unmatched beauty and state-of-the-art performance for energy savings, reduced maintenance and a more comfortable home.

Each window is custom-made from virgin vinyl resin combined with the best stabilizers and impact modifiers for consistent color and strength. Alside insulated glass units use the latest technology to ensure the best possible insulation performance and seal strength. And Alside features a wide array of styles, decorative options, complementary trim selections and performance packages for a fully customizable product to suit your personal style.

Alside windows are custom-made to fit your current window openings precisely. They are easier to install because they require no additional wall construction, in comparison to stock windows found at your local retailer.

Featuring a broad range of styles; from single- and double-hung, sliding, fixed lite, casement and awning, bay, bow and garden window models -- and even patio doors, Alside understands that your vision has no limitations. Without compromising performance or beauty, our unlimited choice of products are designed to bring your vision to reality.


Casement windows are a great way to add drama by bringing in the natural light, creating a larger more open space. They add aesthetic appeal to any type of room.


Awning windows add just the right amount of simplistic elegance to a home. While still letting in the natural light, they can be either crank or push out to let in the beautiful outdoors.

Single/Double Hung

Single and double hung windows provide a simple look with the everyday aspect of an up and down window.


Sliding windows provide ease with maintenance without looking too simple or throwing off your home's aesthetics.

bay & Bow

With either 3 or 5 windows, mulled at 10 degrees, more sunlight enters a room. Add more interest to a room with these unique shapes.


Garden windows add a vintage dimension to the home allowing any warm breezes come through the side vents or to hold your favorite small potted plants year round.
