Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Whether you're updating for aesthetics or have damaged windows, windows play a important role in conserving electricity in your home. According to the Department of Energy, heat gained or lost through traditional, outdated windows could account for 25-30% of heating and cooling costs.

That's also bad news for the environment because the additional energy required by outdated windows increases your carbon footprint.

We've made this list of the top installation companies to help you in your research, so you can not only benefit from brand new windows, but also save money on your electricity bills.

How Installing Energy-Efficient Windows in Cahokia Saves You Money

By switching to energy-efficient windows, you and your family can enjoy several benefits, such as:

  • Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Save on electricity bills: Installing energy-efficient windows reduces your energy bills by about 12% because you use less energy.
  • Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.

Estimated Cost of Window Replacement in Cahokia

Windows come in various shapes and sizes, so costs and services will vary greatly. Here are the average costs and services that you can find from window installation companies.

How Much Do New Windows Cost?

The typical cost to replace a single window is about $600 but can range from $200 to $1,200. But costs 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 installers also offer door installations and replacements, which will make your project cost more.

Whether or not you want to install energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $300 a year on your energy bills in Cahokia.

How much your window installation costs will also vary based on the type of material you choose for the frames. Wood windows are usually the most expensive, although it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

The first step of a replacement is to think about whether you need a full-frame or pocket installation.

A full-frame installation is a total window replacement. This service involves taking out the old window, the sill, and the exterior and interior trim. It also involves additional materials, including insulation and drip edges, which raise the total cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you will likely need a full-frame installation instead.

Your window installer should be able to help you figure out which type of installation you need.

How We Choose the Best Window Installers in Cahokia

EcoWatch differs from most reviewers, as we examine these companies through a sustainability lens. Along with energy efficiency, we reviewed window companies all across the state and ranked them using the following methodology:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

We're certain that you're looking for a company to do a great job installing windows. We've vetted each company on this list to make sure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If most customers don't have nice things to say about their experience with a certain window installation company, it won't be featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window installers won't always provide the highest quality service. Still, we want to ensure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Cahokia's climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Cahokia window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Cahokia, IL Window Replacement FAQs

How much should window installation cost?

The national average cost of replacing one window is around $600 but can range between $200 and $1,200, based on several factors. The price is usually dependent on the size of the window, the type and material of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.

What are the most common types of replacement windows?

The most common kinds of windows for homes are awning windows, slider windows, double-hung and single-hung windows, bay windows, transom windows, picture windows and casement windows.

Do I really need to use a window installation company?

You should hire a window installation professional whenever you need to upgrade your windows. Installing windows is a involved process that can be difficult to do on your own, so it's best handled by the professionals.

How long does it typically 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 have to be installed.

What time of year should I replace my windows?

Replacement windows can be installed at any time, but autumn might be the best season. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into your house, so the temperature outside doesn't necessarily matter that much. What's most important is that the weather should be dry.
