How Installing Energy-Efficient Windows in Alton Saves You Money

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

• Save on energy bills: The Department of Energy estimates that heat gained or lost via windows accounts for around 25-30% of household energy use. Installing energy-efficient windows can help reduce that amount, which helps you save more on your bills.
• Reduce your carbon footprint: In Alton, you can reduce your indirect greenhouse gas emissions by about 642 pounds per year after you install energy-efficient windows.
• Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can improve the insulation in your home and also help raise the value of your home if you decide to sell.
• Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Alton

Let's take a look at the cost of replacing your windows and the kinds of services offered by installers.

How Much Do New Windows Cost?

The typical cost to install a single window is about $600 but can range from $200 to $1,200. These amounts vary based on the specifics of your installation, like material, the location of your home, size, number of windows, type and more.

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 $307 a year on your energy bills in Alton.

The cost of your window installation will also vary depending on the kind of window material you choose for the frames. Wood windows are generally the most expensive, but it depends if they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.

What Services do Window Installers Offer?

The first step when planning a replacement is to figure out whether you need a full-frame or pocket installation.

Full-frame installations entail replacing the total window, including the sill, frame and trim. Full-frame installations are necessary when you want a new style or your window has significant damage. Because full-frame installations are more involved, they will raise the total cost. A pocket installation means replacing a window without taking out the complete frame, which is usually cheaper than a full-frame installation.

If you're unsure which kind of window installation service you should get, your installer can advise you. Generally, the choice is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

Service Area

This one is self-explanatory, but we've chosen to highlight window installation companies that serve Alton so you can find a quality window installation company near you.

Work Quality

When picking new windows, the quality and breadth 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 give window installers more points if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent customer feedback to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including professionalism, quality of parts, quality of installation, warranty, cost and more.

Cost

This one is a give-and-take: as with most services, cheap window companies won't always provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. That's why 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 been in the industry for quite some time. Window installers that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
