Windows That Keep the Outside Outside
If it rattles in the wind, it’s time.
Old windows don’t usually fail all at once — they draft, fog, stick, and quietly drive up energy bills. CNK Enterprises provides professional window replacement designed for Wisconsin weather and everyday use.
We install windows suited for Wisconsin’s climate — accounting for freeze-thaw cycles, wind exposure, and long-term durability. Proper installation matters just as much as the window itself, and that’s where many problems start.
CNK focuses on fit, sealing, and flashing, so your windows perform season after season.
Good windows aren’t exciting. They’re effective.

A door should open smoothly, close securely, and seal properly. If it doesn’t, you’ll feel it — drafts, sticking, water intrusion, or security concerns.
CNK Enterprises installs exterior and entry doors built to perform, not just look good.
Wisconsin weather exposes weak doors fast. CNK installs doors with proper fit, alignment, and sealing so they hold up against wind, rain, snow, and temperature swings.
