How Installing Energy-Efficient Windows in East Alton Saves You Money
Energy-efficient windows can benefit you in several ways. Here are a few reasons you may want to take the plunge and make the switch:
- Save money on power bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save around $283 annually on your energy bills in East Alton.
- Reduce your carbon footprint: By using less energy once switching to energy-efficient windows, you'll also be decreasing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if you have an older home.
Estimated Cost of Window Replacement in East Alton
Windows come in various styles, purposes and shapes, so costs and services will vary greatly depending on several factors. Below, we detail the average cost and services that you can get from window installers.
How Much Do New Windows Cost?
Typically, East Alton homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at around $600. This is because the cost of window installations depend on several factors specific to your home, like the size, material and number of windows you need to install, as well as the location of your property.
Bear in mind that energy-efficient windows may have a higher price, but Energy Star predicts the upgrade will save you between $101 and $583 a year when installing single-pane windows and between $27 and $197 a year when installing double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.
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 offer poor insulation. Vinyl frames are somewhat expensive and offer 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?
The first step when planning a window replacement is to think about whether you should get a full-frame or pocket installation.
Full-frame installations involve replacing the full window, including the frame, trim and sill. You most likely need a full-frame installation when you want a new style or your window has considerable deterioration. Because full-frame installations are more involved, they will increase the total cost. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.
If you're unsure which type of window installation service you should get, your installer can help you out. Typically, the choice is based on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in East Alton
In our search to find the most reliable, eco-friendly window installers in East Alton, EcoWatch chose the above companies as the best window installation companies in the city. Along with energy efficiency, we assessed window companies all across the state and assigned rankings based on the following methodology:
Service Area
Since this is a guide for East Alton, we paid more attention to companies that serve the city. There are certainly reputable providers that didn't make the cut because of the low odds that they would serve the average homeowner in East Alton.
Work Quality
We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each installer on this list to make sure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including quality of installation, professionalism, warranty, cost, quality of parts and more.
Cost
This one is a give-and-take: as with other services, cheap window installers may not provide the highest quality service. Still, we want to ensure we're highlighting companies that offer a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a hefty investment, so you'll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
East Alton, IL Window Replacement FAQs
What is the average cost to install windows in a home?
The national average cost to replace a single window is around $600 but can range from $200 to $1,200, depending on several factors. The price is usually influenced by the size of the window, the type and material of the window and the location of your property. Also, bear in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
Which kind of window is the best?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don't open are more efficient than windows that do. To be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.
What services do window replacement companies do?
Window installation professionals visit your property to remove your old windows and replace them with new ones. Some providers install products sold by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
How often should you replace your windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.
Should I replace my windows all at once?
If your windows are greater than 20 years old, you probably need to replace all of them. At that point, they are typically less efficient, draftier and/or more damaged than new windows. Replacing your windows all at the same time will involve less paperwork and less stress.
