Quoting Costs at a Glance

Every home is different. Some windows are hand made or storm windows from the 1800s, others are modern and built for easy access.

Quotes are based on pane count, size (eg. french panes versus floor to ceiling), accessibility, and condition (eg. recent construction or pets or smokers versus routine touch-ups and little wear).

Know Your Panes, Know Your Costs

An educational infographic comparing windows and panes, showing parts of a window such as the frame, screen, and seal, with labels and descriptions.

When our technicians assess a property and prepare a quote, they count the panes your home has, not the windows.

The cost will reflect whether we are servicing the exterior only (one side of a pane and its screen) or the exterior and interior (both sides of a pane, the screens, tracks, and frame detailing).

Why know the difference?

1) You’ll be better prepared when talking with a professional service provider about a project’s cost.

2) You’ll be able to tell apart a professional from someone looking to make a quick buck, and who could make irreparable damages.
