How Installing Energy-Efficient Windows in Freeport Saves You Money
When you upgrade to energy-efficient windows, you may see some benefits, such as:
- Decrease your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 449 pounds.
- Protect your investment: If you have an older home, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
- Save on power bills: Because energy-efficient windows decrease the amount of energy needed to heat or cool your home, they can help you save around $326 annually on your energy bills in Freeport.
- Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.
Estimated Cost of Window Replacement in Freeport
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?
Generally, homeowners in Freeport can anticipate that most window installations will range from $250 to $1,200, with the average cost sitting at around $600. But costs differ remarkably depending 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 and replacements, which carry a higher price tag.
Bear in mind that energy-efficient windows may come at a higher price point, but Energy Star estimates the upgrade will save you between $101 and $583 a year when you install single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
We advise requesting free quotes from several window installers to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
The first thing to ask yourself when planning a window installation is: Do you want a full-frame installation or a pocket installation?
Full-frame installations involve replacing the complete window, including the trim, sill and frame. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable rot. Because full-frame installations are more involved, they will increase the overall 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 kind of installment if you have any pre-existing rot or water damage.
If you're not sure which type of window installation service you need, your installer should be able to help you out. Typically, the decision is influenced by 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 Freeport
EcoWatch reviews are different from other reviews since we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and ranked them using the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve the Freeport area so you can find a quality window installation company near you.
Work Quality
We're certain that you're looking for professionals who do a great job installing windows. We've vetted each company included on this list to make sure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don't have positive feedback about their experience with a certain company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: similar to most services, cheap window installation companies won't always provide the most quality service. On the other hand, we want to ensure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a sizable investment, so you'll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Freeport's climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Freeport window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Freeport, IL Window Replacement FAQs
What is the average cost to replace windows?
The average cost of installing a window ranges between $450 and $650. There are many factors that influence the price, including local labor costs, styles and sizes of windows, the number of windows, how energy-efficient the windows are, your property's location and the materials used in designing the windows.
What kind of window is the most energy-efficient?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — they're certified energy-efficient by the U.S. Department of Energy.
Can I replace my own windows?
If you're handy and know how to replace a window, it's possible to install your own windows. However, if you don't have the time or know-how, we recommend hiring a professional.
When is the best time of year to replace windows?
While you can install windows any time of year, warmer weather is typically better for installing replacement windows. In addition, it shouldn't be raining, since rain can make the installation more difficult.
Should I replace all my windows at once?
If you want to get more efficient windows and save money on energy costs, replacing all your windows at once is the only way to gain that benefit. However, if you have just one or two windows that are damaged or leaky, you can replace just those.
