The problem
Tired of windows that look worse after a "cleaning"?
Most Bay Area homeowners have hired the wrong crew at least once. Here's what we hear most — and exactly how K2 fixes it.
Streaks, water spots & hard-water haze
Cheap squeegees and tap water leave your glass looking worse than before. We use purified water + pro tools so glass dries spot-free.
Clogged gutters & overflowing downspouts
Bay Area pine needles and oak debris back up gutters fast — leading to fascia rot, foundation cracks, and basement leaks. We clear it all, by hand.
Driveways & siding that make the whole house look tired
Black mildew on stucco, oil stains on concrete, cobwebs under eaves. Soft-wash + pressure-wash brings curb appeal back in a single visit.
