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 environmentally friendly energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your house's energy efficiency can also have a considerable impact on home energy conservation. If you have traditional, outdated windows, your HVAC system could be working overtime to heat or cool your home. This means higher electricity bills.

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

Unlike other sites, EcoWatch ranks window companies on energy efficiency while also balancing cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Thornton Saves You Money

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

  • Protect your investment: If you have a relatively old home, your windows are most likely outdated.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.
  • Save on energy bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Upgrading to energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
  • Decrease your carbon footprint: By using less energy once you switch to energy-efficient windows, you'll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in Thornton

When looking into window installation, each company offers varying services and costs. Let's go over some typical costs and services.

How Much Do New Windows Cost?

According to our research, the typical cost to replace a single window is about $600. However, window installation costs can range from $200 to $1,200 per window. How much it will cost varies depending on several factors, like type, material, the location of your home, number of windows, size and more.

It's also worth bearing in mind that energy-efficient windows will cost more upfront, but Energy Star predicts that upgrading the windows on your Thornton home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Something else that influences the total cost is the material of the frame you pick. Aluminum frames are generally the least expensive and are sturdy and relatively maintenance-free, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and provide 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 typically two kinds of window installation services: full-frame and pocket installations.

A full-frame installation is a total window replacement. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves other materials, such as insulation and drip edges, which raise the overall cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations are simpler and won't cost as much because they involve merely replacing the window within its existing frame. But if the frame has any damage, you should opt for a full-frame installation instead.

Your window installation company can help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Thornton

EcoWatch is different from other reviewers, as we're examining these companies through a sustainability lens. We've evaluated the best window replacement companies in Thornton primarily based on their energy efficient offerings, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Thornton so you can find the right window installation company near you.

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 featured in our guide to ensure its technicians are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.

Customer Reviews

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

Cost

This one is a give-and-take: as with other services, cheap window installation companies are not going to provide the highest quality service. Still, we want to make sure we're highlighting companies that provide a wide range of price and financing options so they're accessible to most homeowners.

Warranty

As discussed, windows are a significant investment, so you'll want to be certain that investment is well protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a proven 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

How much does a window install cost?

The typical cost to install one window can range from $450 to $650. There are a variety of factors that affect how much it costs, such as your property's location, the number of windows, the materials used in designing the windows, how energy-efficient the windows are, local labor costs and styles and sizes of windows.

What type of window is the most energy-efficient?

A window's energy efficiency depends on a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.

When do I need to use a window installation company?

You should hire a window installation company whenever you want new windows. Installing windows is a complex process that can take a lot of time, so it's best handled by the professionals.

How often do you need to replace your windows?

Windows typically have a lifespan of about 20 to 30 years, but anytime you notice damage on your windows, it's a good idea to have an expert take a look at them to determine if they need any repairs or replacements.

Should I replace my windows all at once?

If your windows are greater than 20 years old, you most likely need to replace all of them. By that point, they are usually less efficient, draftier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
