Why you can trust EcoWatch
Although clean energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your home's energy efficiency can also have a big impact on home energy conservation. If you have traditional, outdated windows, your HVAC system could be working overtime to heat or cool your home. This means higher electric bills.
Installing energy-efficient windows on your home can help you save money every month on your electric bills — and you can help the environment, too.
Unlike other review sites, EcoWatch ranks window replacement companies based on energy efficiency while also taking into consideration cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Alton Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to make the switch:
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its value.
- Save money on energy bills: After you upgrade to energy-efficient windows, you can expect a reduction in your bills by about 12% because you'll use less energy to heat or cool your home.
- Reduce your carbon footprint: By using less energy once switching to Energy Star certified windows, you'll also be reducing your carbon dioxide emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Alton
When considering window installation, each company provides varying services and prices. Let's go over some average costs and services.
How Much Do New Windows Cost?
Though the national average to replace a single window is around $600, it can range anywhere from $200 to $1,200. How much it will cost depends on several factors, including the location of your home, material, number of windows, size, type and more.
With windows, efficiency is the most important factor for many homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — especially if you live in a hot climate — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Alton homeowners $460+ each year after replacing single-pane windows.
Costs will also vary depending on the material you want for your window frames. Aluminum frames cost the least. They're sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made with 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 question to ask yourself when getting new windows is: Do you need a full-frame installation or a pocket installation?
Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has a great amount of deterioration. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations are simpler and won't carry as large a bill because they entail merely replacing the window within its existing frame. But if the frame has any damage, you may have to get a full-frame installation instead.
Your window installation company can help you decide which type of installation you need.

How We Choose the Best Window Installers in Alton
In our search to find the most reliable, eco-friendly window installers in Alton, the EcoWatch team assessed many companies before settling on these. We've evaluated the top window installation companies in Alton mainly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy-efficient windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Since this is a guide for Alton, we paid more attention to companies that cover the city. There are other reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Alton.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each installer included on this list to make sure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent customer feedback to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including warranty, quality of parts, quality of installation, cost, professionalism and more.
Cost
This one is a give-and-take: similar to most services, cheap window installers are not going to provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a considerable investment, so you'll want to be certain that investment is protected. Window installation companies that provide 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 installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Alton, TX Window Replacement FAQs
How much does a window install cost?
The national average cost of replacing one window is about $600 but can range from $200 to $1,200, depending on a few different factors. The price is usually dependent on the type and material of the window, the size of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What type of window is the most energy-efficient?
Generally, double-pane windows are more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. To be sure you're getting the most energy-efficient windows, look for models with the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.
What do window installers do?
Window installation companies will do the entire process — from replacing old windows with new ones to cleaning up after the windows have been put in place. Additionally, many companies offer window manufacturing, customization and repairs.
What time of year is a good time to replace my windows?
Though you can install windows any time of year, warmer weather is usually better for installing replacement windows. In addition, the weather should be dry, since rain can make the installation more difficult.
