Double-Pane & Insulated Glass Unit Replacement

Broken or Cracked Units Replaced, Frame Kept

A double-pane window is two sheets of glass sealed together as one insulated glass unit. When one pane cracks or breaks, the whole unit is replaced, but the window frame usually is not. Prestine Glass Solutions replaces broken and cracked double-pane units in homes and commercial buildings across Washington DC, Virginia and Maryland.

If your glass is not broken but has gone cloudy between the panes, the seal has failed. That is covered on our foggy window and IGU replacement page.

Double-Pane Work

Broken or Cracked Units

Impact damage, stress cracks and broken outer or inner panes.

Fogged Units

Moisture between the panes means the seal has failed and the unit needs replacing.

Patio Doors and Large Panels

Sliding door and picture window units, which are heavier and larger.

Replace the Unit, Keep the Window

In most windows the insulated unit sits in the sash or frame held by stops or glazing beads. We remove them, take out the damaged unit, and fit a new one made to the measured size, with the right glass type: tempered where safety glass is required, and low-E where the original had it. That keeps the window you have and avoids a full window replacement when the frame is still sound.

What Happens After You Call

Send photos of the window and the damaged pane, and the rough size. We measure on site, order the unit and come back to install it. If the pane is broken and the opening is not secure in the meantime, ask about a temporary fix. More on 24/7 emergency glass repair.

Frequently Asked Questions

Can you replace just the glass in a double-pane window?

Yes. The insulated unit is replaced and the frame stays, as long as the frame is in good shape.

No. Fog between the panes means the seal failed. Both are fixed by replacing the unit.

We match the glass type and thickness, and low-E coating where the original had it.

No. Prestine works on commercial and residential building glass only. We do not do windshields or vehicle glass.
