How Installing Energy-Efficient Windows in Medford Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here's more information on how upgrading your windows could help you:

• Save money on power bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
• Reduce your carbon footprint: By using less energy after switching to energy-efficient windows, you’ll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
• Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
• Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.

Estimated Cost of Window Replacement in Medford

When researching window installation, each company offers different services and costs. Let’s look at some typical costs and services.

How Much Do New Windows Cost?

Generally, Medford homeowners can expect their window replacements to range from $250 to $1,200. The average cost is at approximately $600. Costs will vary significantly based on the current condition of your home, your location, the quality of your products and the number of windows you need. Many window companies also offer replacement door installations and other add-ons like coating, shutters, baths and more. These extra services will increase your overall project costs.

With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more upfront, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Medford homeowners $464+ per year after replacing single-pane windows.

Another factor that affects the total cost is the material of the frame you select. Aluminum frames are generally the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first question to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?

Full-frame installations involve replacing the complete window, including the trim, sill and frame. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable damage or rot. Because these installations are more involved, they will increase the total cost. Pocket installations (or retrofits) involve installing a new window within its existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any damage or rot, you will most likely need a full-frame installation instead.

Your window installer can help you figure out which type of installation you need.
