How Installing Energy-Efficient Windows in Smithton Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here are more details about how switching out your windows could benefit you:
- 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- Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading and repairing your windows is an important part of maintaining your property and its value.
- Better temperature control in your home: Energy-efficient windows can decrease how hard your heating system needs to work to heat your home.
- Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of residential energy use. Installing energy-efficient windows can help decrease that number, which helps you save some money on your bills.
Estimated Cost of Window Replacement in Smithton
Let's take a look at the cost of installing new windows and the types of services you may need for your home.
How Much Do New Windows Cost?
According to our research, the typical cost to replace a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. How much it will cost depends on several factors, like material, number of windows, type, the location of your home, size and more.
Keep in mind that energy-efficient windows may have a higher price, but Energy Star predicts the upgrade will save you between $101 and $583 per year when you replace single-pane windows and between $27 and $197 per year when you replace double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.
Something else that affects the overall cost is the material of the frame you select. Aluminum frames are generally the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
There are typically two kinds of window installation services: full-frame and pocket installations.
A full-frame installation is a total window replacement. It involves removing the old window, the windowsill, and the exterior and interior trim. It also involves additional materials, such as insulation and drip edges, which increase the total cost of the project. It's also worth noting that it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. A pocket installation involves installing a new window without replacing the frame. This means instead of removing the whole unit and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installer should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Smithton
The EcoWatch Reviews team differs from most reviewers because we're examining these companies through a sustainability lens. We've evaluated the top window replacement companies in Smithton primarily based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your energy 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 Smithton, we paid more attention to companies that cover the city. There are certainly reputable providers that didn't make our list because of the low odds that they would serve the average homeowner in Smithton.
Work Quality
When it comes to new windows, the quality and range of services can often play just as important of a role in insulation and performance as the type of window you choose. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it reflects the quality of services across nearly every category, including quality of parts, quality of installation, professionalism, warranty, cost and more.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. That's why window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Smithton's climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Smithton window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Smithton, IL Window Replacement FAQs
What is the average cost to install new windows?
The national average cost of replacing a single window is around $600 but can range between $200 and $1,200, based on several factors. The price is often dependent on the location of your property, the type and material of the window and the size of the window. Also, remember 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 best for energy efficiency?
A window's energy efficiency is affected by a variety of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
Do you really need to use a window installation company?
You should use a window installation professional whenever you want to replace your windows. Installing windows is a complex process that can take a lot of time, so it's best handled by the professionals.
How often do you need to replace windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they should probably be replaced. Apart from that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.
