Additional window replacement factors

These include:

Window location

-Basement window replacements $250-$1,000+

-Basement egress windows $2,500-$5,000

-Bathroom/bedroom windows $300-$700

-Foyer/dining room windows $300-$700

Large picture, bay or bow windows can double or triple replacement costs while upper-level windows require more installation time and additional equipment adding to labor costs.


Glass size and type

The right glass type can boost energy efficiency lowering utility bills.  Tinted glass helps reduce harmful UV rays, and depending on a home’s geographical location, impact-resistant glass might be an appropriate choice.

In other instances, depending on the location and age of a home, tempered or safety glass might be a requirement by law.


Number of glass panes

The more panes in a window, the more it will cost as a general rule.


Age of house

Older homes come with special challenges like windows requiring custom orders or repairing and replacing rotting and damaged trim.


Full-frame window cost vs. retrofit replacement

The difference is a nail fin, a flange around the edge to attach to the frame directly to the studs found in new construction. Retrofit (replacement) windows cost 10-15% less than new construction and don’t require as much labor.


Labor costs and cleanup

Labor costs average $40/hour ranging from $30-$65/hr. You can save by replacing more windows at once rather than one by one.  Also, if you live in an area with a higher cost of living, your labor costs will also reflect that difference.

When a contractor estimates labor costs, disposal and cleanup are sometimes factored in or added separately.


Structural repairs

This includes repairing trim, siding, or drywall adding $300-$1,100+.


Insulation and weatherproofing

This involves adding insulation in the gaps around a window and can cost $450-$3,300.


Location of job

Your home’s geographical location can significantly affect your window replacement cost(s).  For example, local codes and ordinances can determine the type of frame and glass required for window replacement in your area.

More expensive triple-pane windows are best for cold climates because they provide the most insulation and energy efficiency while double-pane windows typically provide adequate insulation and protection for warmer climates.


Reasons to consider window replacement(s)

  • Difficulty opening and closing
  • Visible damage
  • Higher energy bills
  • Poor outside noise insulation
  • Leaky windows
  • No double glazing
  • Decaying frames

  • Mold growth (can be a serious health hazard)
