ProVia replacement windows. Double-hung, casement, bay, bow, sliders, and awning, measured at the house. This page covers Lexington Park, plus California and Great Mills: 17 ZIP codes in St. Mary's County.
The style is chosen for how the opening should move. We confirm it at the in-home measure.
Both sashes move, and they tilt in so you can clean the outside glass from inside.
Cranks open up to 90 degrees for ventilation, then closes tight against the frame.
Bay, bow, and special-shaped combinations. Framing holds the projection. Flashing keeps it dry.
Horizontal sliders, awning, and single hung when the wall wants a different motion.
You can feel air moving near the frame, or the room by the window never warms up.
Condensation trapped inside the glass means the seal between the panes has failed.
Windows that stick, will not stay up, or will not lock.
Heating and cooling working harder every season often points to the openings.

From 2025-11-11 through 2026-11-11, National Weather Service severe reports for St. Mary's County include this headline: 59 mph winds recorded in St. Marys County. That is a county record. It does not mean every home in these ZIP codes experienced that weather. Wind-driven rain is one reason a new window is foamed and flashed into the wall. We confirm that at the measure, not from a county headline.
