DeMark’s Window and Pressure Cleaning proudly extends our top-rated service; 4.9 stars across 775+ reviews to homeowners throughout Oconomowoc and the surrounding Lake Country communities. Whether you’re on Fowler Lake, Lac La Belle, Okauchee Lake, or Silver Lake, we know exactly what your windows are up against: relentless lake spray, hard-water mineral buildup, pollen drift, and the wear that comes with waterfront exposure.
Our fast-moving, multi-person crews specialize in large, multi-story lakefront estates clearing interior glass, exterior glass, screens, and mirror surfaces efficiently, often in under two hours per home, without sacrificing the detail work your property deserves.
Why Oconomowoc Homeowners Choose DeMark’s
Built for Lakefront Properties Lake spray and wind-driven mineral deposits create a stubborn haze that regular window cleaning can’t touch. Our team uses proven hard-water removal techniques designed specifically for lakefront glass, restoring clarity without streaking or damaging seals.
Sunroom & Multi-Pane Expertise Lake Country homes often feature expansive sunrooms, floor-to-ceiling lake-view windows, and intricate multi-pane grids. Our technicians take the extra time these details require because a streak on a lake-view window is a lot more noticeable than one anywhere else.
Large Crews, Fast Turnaround For sprawling lakefront estates, our multi-man crews work efficiently as a team, minimizing disruption to your day while still delivering the meticulous, mirror-clean finish our reviews consistently mention.
Bundle with Pressure Washing Many Oconomowoc homeowners pair window cleaning with a full exterior soft-wash to tackle dock algae, deck grime, and siding buildup from lake humidity, all in one visit.

What Lake Country Customers Are Saying
“Our crew — Justin and Anthony — had our entire lake house done inside and out faster than I expected, and the windows have never looked better. You could actually see the lake clearly again.”
