How Installing Energy-Efficient Windows in Great Falls Saves You Money

There are quite a few perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the switch are the following:

• Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
• Save money on power bills: Since energy-efficient windows reduce how much energy you need to heat or cool your home, the switch can help you save about $390 annually on your energy bills in Great Falls.
• Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can improve the insulation in your home and also help increase the value of your house if you decide to sell.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Great Falls

Let’s take a look at the cost of installing new windows and the types of services you may need for your home.

How Much Do New Windows Cost?

Typically, homeowners in Great Falls can anticipate that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at around $600. But costs vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also offer door replacements, which will make your project cost more.

With windows, efficiency is the most important factor for most homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Great Falls homeowners $390+ per year after replacing single-pane windows.

Costs will also vary depending on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

The first thing to ask yourself when considering a window replacement is: Do you need a full-frame installation or a pocket installation?

Full-frame installations are usually recommended when you want a new style or your window has a lot of rot or deterioration. With this service, your installers will replace the full window, including the sill, trim and frame. A pocket installation means replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.

If you’re still debating which kind of installation to get, you can talk to your installer and get their advice. The decision mostly depends on how old the frames are and if there’s any damage.
