Replacement windows in this Oakland home

At Winning Windows Inc. we provide a complete range of quality products to suit your every need from our high value Anlin vinyl to high-end Marvin Ultimate Wood and Integrity fiberglass windows, French doors, sliding patio doors, and entry doors.

Save Energy

Energy-efficient replacement windows reduce heating and cooling costs, save energy and improve your personal comfort. All of our windows and doors are Energy Star products which exceed the federal energy star guidelines and the standards of California Title 24 Energy Standards in the reduction of energy use to help you reduce your environmental footprint and save on today’s rising energy costs. Title 24 was established by legislation in order to reduce California’s energy consumption.


When choosing a window style, look to your home’s architectural style for guidance. Traditional or modern, grids or clear glass, casements, double hungs, awnings, single hungs, sliders, picture windows, geometrics, sliding patio and hinged French Doors — we’ve got you covered. Whether you want to preserve or maximize your amazing view with a casement window, or let out steam from the shower with a double hung, we’ve got the solution. If you live on a noisy street, we can minimize those sounds for you, too

Our window installation will depend on the best solution for your home.

An insert or retrofit installation leaves the perimeter frame intact, so as not to disrupt the existing flashing, stucco, or siding. An insert installation works well with existing wood framed windows with sloped sills where the existing wood sills are in good condition. Retrofit installations are also used on stucco homes with existing aluminum or steel windows which are weather tight and not showing any signs of water entry.

With a new construction or nail fin installation, the entire window frame is removed. This is the preferred method if there are any signs of water entry or the window frames are severely damaged. Because of the extra time required, this is a more costly installation.

“I had a great experience with Winning Windows. Windows came on time, were well-installed, and they look great.” — Alex G., Yelp

Entry Doors

Whether ornate with decorative glass, simply adorned craftsman, mid-century modern, or contemporary, an entry door can reflect your artistic imagination, or support the original architectural style of your home. We work with you to find a style that reflects your taste with materials, glass, and hardware. While wood doors offer a beautiful natural grain and high-end look, they require regular maintenance. As an alternative, fiberglass doors can be used in locations that have exposure to sun, wind, and moisture. With either choice, your doors will be beautiful and last a lifetime.

Low-E 3 windows have three layers of silver coating applied to the window, insulating your rooms in colder weather and keeping the heat out in warm weather. It blocks 95% of the sun’s damaging ultraviolet rays (a leading cause of fading), so it will help your furniture, carpets, curtains as well.
