How Installing Energy-Efficient Windows in Oak Park Saves You Money

When you switch to energy-efficient windows, you may see several benefits, such as:

• Save money on electricity bills: Installing energy-efficient windows lowers your energy bills by about 12% because you use less energy.
• Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
• Decrease your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Oak Park, that’s about 449 pounds per year on average.
• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.

Estimated Cost of Window Replacement in Oak Park

Each window replacement company provides varying services and has varying prices based on several factors.

How Much Do New Windows Cost?

Though the average cost of replacing a single window is around $600, it can range anywhere from $200 to $1,200. These estimates vary based on specific characteristics of your installation, such as material, size, number of windows, type, the location of your home and more.

With windows, efficiency is the most important factor for many homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Oak Park homeowners $295+ a year after replacing single-pane windows.

How much your window installation costs will also vary depending on the kind of window material you choose for the frames. Wood windows are typically the most expensive, but it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

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

Full-frame installations involve replacing the complete window, including the sill, frame and trim. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable rot. These installations are more involved and will increase the total cost. A pocket installation involves replacing a window within the frame that’s already there. So, instead of tearing out the whole window and rebuilding it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.

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