Our most affordable patio door: a vinyl slider with welded corners, an aluminum track and heavy-duty rollers.
The Cascade WinPro is the most affordable patio door we install, and it doesn't cut corners where it counts. The vinyl frame is reinforced with aluminum, the frame and sash corners are welded, and the panels ride on adjustable heavy-duty rollers over an aluminum track instead of a vinyl one.
It's a smart pick for replacing a drafty aluminum or builder-grade slider, for rentals, and for anyone who wants a new, efficient door without paying for a premium frame. Cascade backs it with a limited lifetime warranty for as long as the original owner lives in the home. We measure, order, remove the old slider, and install the new one.

Welded frame and sash corners help keep water and drafts out, and aluminum reinforcement inside the vinyl keeps the panels straight and strong.
An aluminum track and adjustable heavy-duty rollers keep the door gliding easily. A single-point lock is standard, with a multi-point lock as an upgrade.
Go beyond white with almond or clay vinyl, or choose a black or bronze cap stock exterior for a darker, more modern look from the yard.
Two- and three-panel doors come in standard sizes, and four-panel doors are made to size. The moving panel can go on either side.
The classic slider: one panel moves and one stays put. Standard sizes fit most existing openings, and Low-E glass with argon gas and grid options keeps the room comfortable.
For a wider opening, add panels for more glass and a bigger view. Three-panel doors come in standard sizes, and four-panel doors are built to fit your opening.
Five exterior colors and three interior colors. The handle comes color-matched to the door.
Swatches are approximate. We bring real color samples to your free in-home estimate.

Our own crews remove your old slider, install the new Cascade door, and seal it for Puget Sound weather. Cascade's limited lifetime warranty covers the door, and our 5-year workmanship warranty covers the install.
