Why there is no price on this page

Nobody can give a firm price for replacement windows from a web page. The number depends on how many windows, their size, the style, the glass.

What a web page can do is tell you what shifts the number, so the price you are eventually given makes sense and you can compare two quotes on the same terms.

What makes the price go up or down

  • How many windows. Per-window cost usually falls as the count goes up, because the crew sets up once.

    Count: fewer windows on the left, more on the right.FewerMore

  • Size. A large unit costs more than a small one of the same style, and very large glass can need two people to set.

    Size: a small window on the left, a large one on the right.SmallLarge

  • Style. A fixed picture window is the simplest. Bay and bow units cost the most because they carry structural work.

    Style: a flat picture window on the left, a projecting bay on the right.PictureBay

  • Glass package. Double against triple pane, the coating on the glass, and the gas between the panes.

    Glass: two panes on the left, three panes on the right.DoubleTriple

  • Access. Upper floors and anything needing scaffolding takes longer.

    Access: a window at ground level on the left, an upper-floor window reached by ladder on the right.GroundUpper floor

  • Finish work. Interior trim, exterior wrap and paint are separate from the window itself.

    Finish: interior trim fitted around the new window.Trim

Comparing two quotes

  • Check the two quotes cover the same number of windows at the same sizes. A cheaper quote is sometimes a shorter list.
  • Check the glass package. Pane count and coating change the price and are easy to miss on a summary line.
  • Check what finish work is included, and whether removal of the old units is in the price.
  • Check which part of the work each warranty term applies to.
