Will New Windows Save You Money?

Sometimes companies that sell replacement windows exaggerate how much money people might save on their heating and cooling bills when new windows are installed. The truth is the money you could save depends on several factors:

What material your existing windows are made of?
How well your home is insulated?
The size of your home and how many windows it has.
The shade around your home.
The climate you live in.

Of course, when deciding whether new windows will save you money, it’s important to consider the upfront costs. The price per window can range from a few hundred to a few thousand dollars, depending on the materials and features you choose and cost of installation.

Are new windows more secure?

Depending on the age or current condition of your existing windows, replacement windows are likely to be more secure.  They will have stronger frames, thicker glass, and better locking systems.  Energy efficiency and appearance are all great reasons to replace windows, but isn't the security of your home just as important?

Window Material and Options

The choices you make about materials, style, glazing, and installation could have a big impact on your energy bill. And some features, like how easy they are to take care of, make windows more appealing for other reasons.

Window Materials

Different window frame materials can affect the appearance, durability, and insulation of your window. For example, wood-framed windows provide good insulation but are heavy and high-maintenance. Vinyl-frame windows insulate well and don’t need painting.

Window Style

The style of a window can affect how well your window insulates. Single-hung, double-hung, and sliding windows leak more air than casement, awning, and hopper windows.

Glass Technologies

Certain window glazes and glass may provide better insulation, light quality, and condensation resistance. For example, windows with low-emissivity (low-e) coatings often are more energy efficient than windows without.

Cleaning and Maintenance

Some materials and features, like tilt-in sashes, make windows easier to care for.

Certified Installation

If your windows are not installed according to the manufacturer’s instructions, you might not get the savings or comfort you expect.  We are Marvin Certified and all of our installers work only for us.

NFRC Label

Look for the National Fenestration Rating Council’s window label when you shop. It can help you compare how well a window blocks cold, heat, and outside air; allows light in; and blocks condensation.
