A sealed unit made to fit your window

An insulated glass unit, or IGU, contains panes separated by a spacer and sealed around the edge. When the unit fails, we replace it as a complete assembly. We check the frame and sash before deciding whether glass-only replacement is suitable.

The details that make the replacement fit

Glass and spacer dimensions

We check pane thickness and spacer depth as well as width and height. The replacement must fit the sash and its glazing system.

Low-E coatings and tint

We identify existing coatings and tint, then discuss the replacement specification. This helps the new unit suit the surrounding glass.

Fixed and opening windows

We work with insulated units in picture windows and operable wood, vinyl and aluminum windows. Many patio doors also use insulated glass.

Failed seals or broken glass

A cracked pane and moisture trapped inside the unit both need attention. A new factory-sealed unit replaces the failed assembly; we do not offer defogging as the repair.

A replacement specified for the opening.

The complete sealed assembly is measured and ordered for the existing window. Frame suitability and the glass details come before installation.

More about our process
  1. Start with the affected window

    Send your city or ZIP and tell us whether the glass is cracked, cloudy or otherwise damaged. Staff clarify the request and normally email an estimate or proposal before work is arranged.

  2. Inspect and measure

    We check the frame and sash, identify the glass, and measure the opening before ordering a replacement.

  3. Order the insulated unit

    We order glass with the agreed dimensions, spacer depth, tint and coatings.

  4. Install the glass

    We remove the failed glass, prepare the opening and set the replacement with appropriate setting blocks and sealants.

  5. Check and clean

    We check window operation and seals, clean the glass and remove old materials.

Double-pane glass questions.

A few practical details about assessing and replacing your glass.

Ask about your glass
Can you replace just one pane of a double-pane unit?

Our service replaces the failed insulated glass unit as a sealed assembly. The existing window frame and hardware can remain when they are in suitable condition.

Do you defog the old glass?

No. We replace failed insulated units with new sealed glass.

How many visits will it take?

We measure first, then return once the custom unit is ready. Many replacements are installed in one visit after fabrication; access and the number of windows affect scheduling.

Can you secure broken glass before the new unit arrives?

Ask about temporary board-up if the opening cannot be glazed right away.

Replace the sealed glass, keep a suitable frame.

We check the opening and match the replacement specification to it. Ask about a new insulated unit rather than assuming the entire window needs replacing.
