Freeport Window Cost Calculator

Calculate how much you can expect to pay for window installation and replacement in Freeport, IL using our customized window cost calculator.

Estimated Window Cost:
161 homeowners have requested a free estimate in the last 3 days.

Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

How Installing Energy-Efficient Windows in Freeport Saves You Money

By upgrading to energy-efficient windows, you can benefit in several ways, including:

  • Save money on energy bills: The Department of Energy estimates that heat gained or lost via windows makes up around 25-30% of residential energy use. Upgrading to energy-efficient windows can help reduce that number, which helps you save more on your bills.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
  • Better temperature control in your home: Living in a very cold place like Freeport can often mean relying on your heater to keep your home cool. Energy-efficient windows can reduce the amount of heat lost through your windows when heating your home.

Estimated Cost of Window Replacement in Freeport

Windows come in all shapes and sizes, so costs and services will vary considerably. Here are the typical costs and services that you can find from the average window installation company.

How Much Do New Windows Cost?

The national average cost to replace a single window is about $600 but can range from $200 to $1,200. But prices vary considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations and replacements, which will make your project cost more.

Keep in mind that energy-efficient windows may cost more, 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. Your exact savings will 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 are the types of windows?

There are several different types of windows you can get for your home, including bay windows, double-hung and single-hung windows, casement windows, transom windows, slider windows, awning windows and picture windows.

What services do window installation companies provide?

Window installation professionals visit your home to remove your old windows and replace them with new ones. Some companies install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.

When is it time to replace your windows?

Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.
