## The windows Alton asks for

We're a St. Louis window and door company that's been family-owned since 1953. We bring the same crews and the same standard to Alton that we hold at home, whether it's a single window, a new front door, or a whole-home replacement.

Alton climbs the bluffs above the Mississippi, and its streets hold some of the oldest housing in the metro: brick Victorians on Christian Hill, frame homes through Middletown and Upper Alton. Houses like these deserve an honest answer, not an automatic sales pitch. If a foggy pane or a worn sash can be repaired, we repair it. When a window is truly done, we replace it with one sized to the original opening so the house keeps its character.

### Double-hung windows

The St. Louis classic: both sashes open, both tilt in to clean.

### Casement windows

Crank-out windows that seal the tightest and catch a breeze.

### Sliding windows
