How Installing Energy-Efficient Windows in Festus Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here's more information on how upgrading your windows could help you:
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Festus, that’s about 763 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 Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
- Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Replacing your windows with energy-efficient models can help lower how much you have to pay, therefore saving you about 12% more on your bills.
- Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out harmful UV rays.
Estimated Cost of Window Replacement in Festus
Windows come in various shapes, styles and purposes, so costs and services will differ greatly depending on your project. Below, we detail the average cost and services that you can get from window installation companies.
How Much Do New Windows Cost?
The typical cost to install a single window is about $600 but can range from $200 to $1,200. But prices vary remarkably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations, which will make your project cost more.
It’s important to remember that windows with the best efficiency may cost more upfront but can save you hundreds of dollars by lowering your energy bills. Investing in Energy Star certified windows can save Festus homeowners $370+ a year when replacing single-pane windows.
Something else that influences the total cost is the material of the frame you select. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
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 involve replacing the total window, including the trim, frame and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable damage. These installations are more involved and will raise the overall cost. A pocket installation involves installing a new window without replacing the frame. So, instead of tearing out the whole unit and reinstalling it, the installer will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company can help you choose which type of installation you should get.

How We Choose the Best Window Installers in Festus
In our search to make your home improvements easier and more eco-friendly in Festus, the EcoWatch team assessed many companies before deciding on these. We’ve reviewed the best window installation companies in Festus mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Festus, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Festus.
Work Quality
We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company in our guide to make sure its technicians are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including cost, quality of installation, warranty, quality of parts, professionalism and more.
Cost
This one is a give-and-take: as with most services, cheap window companies may not provide the most quality service. Still, we want to ensure we’re highlighting companies that provide a wide range of price and financing options so they’re accessible to most homeowners.
Warranty
As discussed, windows are a serious investment, so you’ll want to be certain that investment is well protected. Window installation companies with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Festus, MO Window Replacement FAQs
What is the average cost to install new windows?
The average cost to replace a single window can range from $450 to $650. There are several factors that affect the price, which include your property’s location, local labor costs, the number of windows, how energy-efficient the windows are, the materials used in designing the windows and styles and sizes of windows.
What type of window is the best for energy efficiency?
Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open will be 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 attached to them — this means they’re certified energy-efficient by the U.S. Department of Energy.
What services do window installation companies provide?
Window installation professionals cover the entire process — from replacing your old windows with brand-new ones to cleaning up after the installation. In addition, many companies offer window manufacturing, customization and repairs.
