How Installing Energy-Efficient Windows in Carol Stream Saves You Money

By upgrading to energy-efficient windows, you and your family can benefit in several ways, such as:

• Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In Carol Stream, that’s about 449 pounds per year on average.
• Save on electricity bills: Since energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save around $300 annually on your energy bills in Carol Stream.
• Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in Carol Stream

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

How Much Do New Windows Cost?

Generally, homeowners in Carol Stream can anticipate that most window installations will cost between $250 and $1,200, with the average cost sitting at about $600. This is because the cost of window installations depend on several factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.

It’s also worth keeping in mind that energy-efficient windows will almost always cost more initially, but Energy Star estimates that switching out the windows on your Carol Stream 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 varies based on your local climate, energy rates and other factors unique to your home.

What Services do Window Installers Offer?

When considering window replacements, in general there are two kinds that your provider will offer: full-frame and pocket installations.

Full-frame installations entail replacing the complete window, including the sill, trim and frame. Full-frame installations are necessary when you want a new style or your window has significant damage or rot. Because these installations are more involved, they will increase the total cost. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations take less time and therefore cost less. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

Your window installation company should be able to help you choose what’s best for your needs. In Carol Stream, the decision will mostly be based on how old your windows are and if there’s any moisture damage. Wood can decay if it’s not properly maintained over the years, so it’s good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Carol Stream

EcoWatch is different from most reviewers, as we’re examining these companies through a sustainability lens. Along with energy efficiency, we assessed window companies all across the state and ranked them based on the following methodology:

Service Area

This one is 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 willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each company included on this list to ensure its contractors are well-qualified and that the company has gotten 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 good feedback 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 other services, cheap window installers won’t always provide the most quality service. On the other hand, 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

As discussed previously, windows are a substantial investment, so you’ll want to make sure that investment is protected. Window installation companies that have 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 good track record in the industry. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
