How Installing Energy-Efficient Windows in St. Charles Saves You Money

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

• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
• Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In St. Charles, that’s about 763 pounds per year on average.
• Save 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 $382 annually on your energy bills in St. Charles.
• Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.

Estimated Cost of Window Replacement in St. Charles

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

How Much Do New Windows Cost?

According to our market research, the national average cost of installing a single window is around $600. However, window installation costs can range from $200 to $1,200 per window. But costs differ remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door replacements, which will make your project cost more.

With windows, efficiency is the most important factor 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, buying certified energy-efficient windows can save St. Charles homeowners $382+ each year after replacing single-pane windows.

Costs will also vary based on the material you want for your window frames. Aluminum frames have the lowest price. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are a bit more 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 offer decent insulation for your home.

What Services do Window Installers Offer?

Generally, there are two types of window installation services companies provide: full-frame and pocket installations.

Full-frame installations are usually recommended when you want a new style or your window has a lot of deterioration. With this service, your installers will replace the whole window, including the trim, sill and frame. Pocket installations are on the simpler end and won’t carry as large a bill because they involve merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.

If you’re still trying to decide which type of installation you need, you can talk to your provider and get their recommendation. The decision mostly is influenced by the age of your window frames and if there’s any damage present.
