How Installing Energy-Efficient Windows in Mascoutah Saves You Money
When you switch to energy-efficient windows, you may see several benefits, including:
- 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 Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Decrease your carbon footprint: By using less energy after you switch to Energy Star certified windows, you'll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
- Save money on power bills: After you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll require less energy to heat or cool your home.
Estimated Cost of Window Replacement in Mascoutah
When researching window installation, each company provides varying services and costs. Let's go over some typical costs and services.
How Much Do New Windows Cost?
The average cost to replace one window is about $600 but can range from $200 to $1,200. But costs vary remarkably 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. Windows with higher efficiency may cost more off the bat, 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 Mascoutah homeowners $321+ a year after replacing single-pane windows.
How much your window installation costs will also vary depending on the kind of material you choose for the frames. Wood windows are generally the most expensive, although it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first question to ask yourself when planning to replace your windows is: Do you need a full-frame installation or a pocket installation?
Full-frame installations entail replacing the total window, including the sill, trim and frame. Full-frame installations are necessary when you want to change the style of your windows or your window has significant deterioration. Because full-frame installations are more involved, they will increase the overall cost. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any damage or rot, you will most likely need a full-frame installation instead.
Your window installation company will be able to help you choose what's best for your needs. In Mascoutah, the decision will mostly depend on how old your windows are and if there's any damage. Wood can decay if it's not properly maintained over the years, so it's a good idea to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Mascoutah
The EcoWatch Reviews team is different from most reviewers because we evaluate these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and ranked them based on the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.
Work Quality
When choosing new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don't have good things to say about their service from a certain company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window installers won't always provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that provide a range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a substantial investment, so you'll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Due to Mascoutah's climate, homeowners need to be wary of low efficiency, rot and water damage. We factored in local experience to reflect the ability of Mascoutah window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Mascoutah, IL Window Replacement FAQs
What is the typical cost to replace windows in a home?
The average cost to install a window can range from $450 to $650. There are several factors that influence how much it costs, such as local labor costs, styles and sizes of windows, the number of windows, how energy-efficient the windows are, your property's location and the materials used in designing the windows.
What are the most common kinds of replacement windows?
There are several different types of windows you can get for your house, such as awning windows, bay windows, casement windows, picture windows, double-hung and single-hung windows, slider windows and transom windows.
What do window installation companies do?
Window installers visit your home to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others install their own windows. The installer will also clean up after the installation is complete.
How long does it usually take to install windows?
Each window takes around 30 minutes to install depending on the type of window. However, the window installation can take two days or more if you have a lot of windows that have to be installed.
How often should you replace windows?
Windows typically have a lifespan of around 20 to 30 years, but anytime you notice damage on your windows, it's a good time to have them checked by an expert to see if they need any repairs or replacements.
