How Installing Energy-Efficient Windows in Thornton Saves You Money

By switching to energy-efficient windows, you and your family can take advantage of several benefits, including:

  • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Thornton, that’s about 449 pounds per year on average.
  • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its value.
  • 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.
  • Save on electricity bills: Switching to energy-efficient windows reduces your energy bills by about 12% because you use less energy.

Estimated Cost of Window Replacement in Thornton

Let’s go over the cost of window installation and the kinds of services offered by installers.

How Much Do New Windows Cost?

The national average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. This is because of the fact that window installations depend on several factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.

Whether or not you opt for energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $295 a year on your energy bills in Thornton.

Something else that affects the overall cost is the material of the frame you pick. Aluminum frames are usually the least pricey and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.

What Services do Window Installers Offer?

There are generally two kinds of window replacement services: full-frame and pocket installations.

Full-frame installations involve replacing the total window, including the trim, frame and sill. Full-frame installations are necessary when you want a new style or your window has considerable damage. Because these installations are more involved, they will raise the total cost. A pocket installation entails replacing a window without replacing the frame. This means instead of removing the whole unit and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

If you’re still trying to decide which kind of installation to get, you can ask your provider and get their recommendation. The decision mostly depends on the age of your window frames and if there’s any damage present.

How We Choose the Best Window Installers in Thornton

EcoWatch reviews are different from other reviews because we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed window companies all across the state and assigned rankings using the following methodology:

Service Area

Because this is a guide for Thornton, we paid more attention to companies that serve the city. There are certainly other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Thornton.

Work Quality

When picking new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand of window you opt for. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don’t have positive feedback about their service from a certain installer, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: similar to other services, cheap window installers are not going to provide the highest 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

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

Lastly, we like to see companies that have a good track record in the industry. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Thornton, IL Window Replacement FAQs

What is the typical cost to replace windows in a home?

The typical cost to replace one window ranges between $450 and $650. There are several factors that influence how much it costs, including styles and sizes of windows, how energy-efficient the windows are, the materials used in designing the windows, the number of windows, local labor costs and your property’s location.

What are the different kinds of windows?

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

What services do window installation companies offer?

Window installers go to your house to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is done.

When is the best time of year to replace windows?

Replacement windows can be installed any time of the year, but autumn might be the best season. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn’t get into the home, so the temperature outside doesn’t necessarily matter that much. What’s more important than the temperature is that the weather should be dry.

How long does it typically take to install windows?

Each window takes around 30 minutes to install depending on the type of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
