How Installing Energy-Efficient Windows in Mount Vernon Saves You Money
By upgrading to energy-efficient windows, you can enjoy several benefits, including:
- Protect your investment: If you have a relatively old home, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your home if you decide to sell.
- Save money on electricity bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save around $302 annually on your energy bills in Mount Vernon.
- Decrease your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 642 pounds.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
Estimated Cost of Window Replacement in Mount Vernon
Let's go over the cost of replacing your windows and the types of services offered by installers.
How Much Do New Windows Cost?
The average cost to install one window is about $600 but can range anywhere from $200 to $1,200. But prices differ considerably 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 offer door installations, which will make your project cost more.
It's also worth bearing in mind that energy-efficient windows will cost more upfront, but Energy Star estimates that upgrading the windows on your Mount Vernon home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
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 100% 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?
There are typically two kinds of window replacement services: full-frame and pocket installations.
Full-frame installations require replacing the entire window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has significant damage. Full-frame installations are more comprehensive and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and won't carry as large a bill, but you can't do this type of installment if you have any pre-existing rot or water damage.
If you're not sure which window installation service you should get, your installer should be able to help you out. In general, the choice is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Mount Vernon
EcoWatch differs from most reviewers since we examine these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Mount Vernon and assigned rankings based on the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve Mount Vernon so you can find the best window installation company near you.
Work Quality
When selecting new windows, the quality and range of services often plays just as important of a role in overall efficiency and performance as the brand of window you get. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another super important review factor. If the majority of customers don't have nice feedback about their service from a certain company, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers' prices, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
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 offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Mount Vernon, IL Window Replacement FAQs
How much does window installation cost?
The national average cost of installing a single window is about $600 but can range between $200 and $1,200, depending on several factors. The price is typically dependent on the size of the window, the location of your property and the type and material of the window. Also, bear in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What are the most common types of replacement windows?
There are several different types of windows you can get for your house, such as picture windows, double-hung and single-hung windows, casement windows, slider windows, bay windows, transom windows and awning windows.
What do window installation companies do?
Window installation companies cover the entire process — from replacing old windows with brand new ones to cleaning up after the windows have been put in place. In addition, some companies offer window manufacturing, customization and repairs.
How long does it generally take to install windows?
Each window takes about 30 minutes to install based on the type of window. However, the window installation can take two days or more if you have a lot of windows that must be installed.
Should I replace all my windows at the same time?
If you're upgrading your windows because of energy-efficiency, replacing all of the windows together is the only way to see a noticeable difference. However, if you have just a few windows that are broken or drafty, you can replace just those.
