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 green energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your home’s efficiency can also have a big impact on home energy conservation. Drafty or leaky windows can make your home uncomfortable in the summer or winter.

That’s also bad news for the environment because the extra energy used by old windows increases your carbon footprint.

Efficient windows are especially important in DeKalb, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $298 each year.

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 DeKalb Saves You Money

There are quite a few benefits of upgrading to energy-efficient windows. Some reasons you may want to consider making the change include the following:

  • Save on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Switching to energy-efficient models can help reduce that amount, therefore saving you about 12% more on your bills.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
  • Decrease your carbon footprint: Decreasing the amount of energy you use also lowers your carbon emissions. You could reduce it by 449 pounds per year on average.

Estimated Cost of Window Replacement in DeKalb

Each window installation company provides varying services and has varying price points based on a few factors.

How Much Do New Windows Cost?

Even though the average cost of installing one window is about $600, it can range from $200 to $1,200. But prices differ 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 provide door installations and replacements, which will add extra costs to your project.

It’s also worth noting that energy-efficient windows will almost always cost more initially, but Energy Star estimates that switching out the windows on your DeKalb home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. The amount of money you’ll save by upgrading 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 based on the kind of window material you choose for the frames. Wood windows are usually the most expensive, although it depends on whether they are solid 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?

The first question to ask yourself when planning a window installation is: Should you get a full-frame installation or a pocket installation?

Full-frame installations involve replacing the entire window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has significant damage. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations are simpler and won’t cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.

If you’re not sure which window installation service you should get, your installer can assist you. Typically, the choice depends 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 DeKalb

In our search to make your home improvements easier and more eco-friendly in DeKalb, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. We have evaluated the best window installers in DeKalb mainly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for DeKalb, we only included companies that provide services to the city. There are other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in DeKalb.

Work Quality

We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer included on this list to make sure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including warranty, professionalism, cost, quality of parts, quality of installation and more.

Cost

This one is a give-and-take: as with other services, cheap window installers may not provide the highest quality service. Still, we want to make sure 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. That’s why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

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

DeKalb, IL Window Replacement FAQs

How much should a window install cost?

The typical cost to replace one window ranges from $450 to $650. There are a variety of factors that affect the cost, which include styles and sizes of windows, the number of windows, the materials used in designing the windows, local labor costs, how energy-efficient the windows are and your property’s location.

What are the different kinds of windows?

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

Can I install my own windows?

Even though it is possible to install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Using a window replacement company can help guarantee that the job is done properly and that you won’t have to spend the time and effort to do it yourself.

How do you know it’s 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 should probably be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to operate, they may be in need of replacement.

How long does it usually take to install windows?

Each window takes around 30 minutes to install depending on the kind of window. However, the window installation can take two days or more if you have a lot of windows that must be installed.
