How Installing Energy-Efficient Windows in Alton Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on energy bills. Here are more ways upgrading your windows could benefit you:

• Save on power bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you use less energy.
• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, particularly if you have an older home.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing your furniture, carpet and other valuables from fading.
• Reduce your carbon footprint: Because energy-efficient windows improve the insulation in your house, you can cut your indirect greenhouse gas emissions by about 12%, according to Energy Star.

Estimated Cost of Window Replacement in Alton

Each window installer provides varying services and has different price points depending on a few factors.

How Much Do New Windows Cost?

The average cost to replace one window is about $600 but can range anywhere from $200 to $1,200. But costs vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also offer door installations, which will add extra costs to your project.

With windows, efficiency is one of the most important factors for many homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Alton homeowners $313+ per year after replacing single-pane windows.

Requesting free quotes from several companies is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

There are generally two types of window installation services: full-frame and pocket installations.

A full-frame installation replaces the entire window, including the sill, frame, trim and the window panes. As this type of installation is more involved, it will cost more than a pocket installation. Pocket installations (or retrofits) involve replacing a window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any damage or rot, you will most likely need a full-frame installation instead.

Your window installation company should be able to help you choose which type of installation you need.

How We Choose the Best Window Installers in Alton

EcoWatch differs from most reviewers because we evaluate these companies through a sustainability lens. We’ve reviewed the best window replacement companies in Alton primarily based on energy efficiency, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows have been shown to lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve the Alton area so you can find the best window installation company near you.

Work Quality

When picking new windows, the quality and range of services often plays 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 consider workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another very important review factor. If most customers don’t have good things to say about their experience with a certain company, it won’t be featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window installation companies may not provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that provide a spectrum 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 that provide 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 been in the industry for quite some time. Window installation companies 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.
