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.

Although clean energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your home's energy efficiency can also have a considerable impact on home energy conservation. The Department of Energy estimates that heat or cool air lost through traditional or outdated windows could be responsible for around 30% of heating and cooling use. In Granite City, where the energy bills are an average of $26 per month, that's almost $$95 per year wasted.

That's bad for your wallet and the environment, but one of the best window installation companies can help you with that.

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

How Installing Energy-Efficient Windows in Granite City Saves You Money

Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to consider making the switch:

  • 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 because of their ability to filter out harmful UV rays.
  • Save on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of residential energy use. Switching to energy-efficient windows can help decrease that amount, which helps you save $313 a year on your bills.
  • 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 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 Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Granite City

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

How Much Do New Windows Cost?

Typically, Granite City homeowners can anticipate their window installations to range from $250 to $1,200. The average cost is at approximately $600. These numbers vary based on specific characteristics of your installation, such as material, the location of your home, number of windows, size, type and more.

Whether or not you choose 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 $313 a year on your energy bills in Granite City.

We advise getting free quotes from multiple window companies to find the right windows and the company that works best for you.

What Services do Window Installers Offer?

The first step of a window installation is to think about whether you should get a full-frame or pocket installation.

Full-frame installations involve replacing the whole window — the sill, frame, trim and all. These are typically done when you want a new style for your windows or when it has a great amount of deterioration. Full-frame installations involve more time and labor 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 will be less expensive, 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 kind of window installation service you need, your installer can help you out. Generally, the decision depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Granite City

EcoWatch differs from most reviewers, as we look at these companies through a sustainability lens. We have assessed the best window installation companies in Granite City mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can cut your electricity 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 Granite City, we only included companies that provide services to the city. There are certainly reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Granite City.

Work Quality

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

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including cost, quality of parts, warranty, quality of installation, professionalism and more.

Cost

This one is a give-and-take: similar to most services, cheap window companies 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

As discussed, windows are a substantial investment, so you'll want to make sure 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 years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Granite City, IL Window Replacement FAQs

How much does window installation cost?

The national average cost to install a single window is around $600 but can range from $200 to $1,200, depending on several factors. The price is often influenced by the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

Which kind of window is the best?

Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you're getting the most energy-efficient windows, look for models that have the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.

Do I really need to use a window installation company?

You should hire a window installation company whenever you need to upgrade your windows. Installing windows is a complicated process that can take a lot of time, so it's best left to the professionals.

How long does it take to install windows?

Because the average installation time of a window is 30 minutes, about 16 windows can be installed in an 8-hour work day.

When is the best time of year to replace windows?

Replacement windows can be installed any time of the year, but warmer weather is typically better. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into the house, so the temperature outside doesn't necessarily matter that much.
