How Installing Energy-Efficient Windows in South Rock Island Saves You Money

When you switch to energy-efficient windows, you may see a few benefits, such as:

• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
• Protect your valuables from fading: When you upgrade to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out harmful UV rays.
• Save on energy bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you’ll need less energy to heat or cool your house.
• Reduce your carbon footprint: You can reduce your carbon footprint by about 12% after you install Energy Star certified windows. In South Rock Island, that’s about 478 pounds per year on average.

Estimated Cost of Window Replacement in South Rock Island

Windows come in varying shapes and sizes, so costs and services will vary tremendously. Here are the average costs and the primary services that you can find from the average window installation company.

How Much Do New Windows Cost?

Generally, homeowners in South Rock Island can expect that most replacement window installations will range from $250 to $1,200, with the average cost at around $600. These numbers vary based on the specifics of your installation, such as size, type, the location of your home, material, number of windows and more.

It’s also worth keeping in mind that energy-efficient windows will usually cost more initially, but Energy Star predicts that upgrading the windows on your South Rock Island home can mean an average energy savings of $236 to $319 each 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.

Another factor that affects the total cost is the material of the frame you select. Aluminum frames are usually the least pricey and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive because 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?

The first step when considering a replacement is to decide whether you need a full-frame or pocket installation.

A full-frame installation is a total window replacement. It involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve extra materials, such as insulation and drip edges, which raise the overall cost of the project. It’s also worth noting that it’s not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. A pocket installation means replacing a window without removing the whole frame, which tends to be less expensive than a full-frame installation.

If you’re hiring a reputable window installation company, your company will be able to recommend the best type for your project. In South Rock Island, the decision will mostly be based on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in South Rock Island

EcoWatch reviews are different from other reviews, as we’re examining these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and assigned rankings using the following methodology:

Service Area

Because this is a guide for South Rock Island, we only included companies that provide services to the city. There are other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in South Rock Island.

Work Quality

When installing new windows, the quality and range of services often plays just as important of a role in insulation and performance as the type of window you choose. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including cost, professionalism, quality of installation, quality of parts, warranty and more.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

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

Years of Experience

Due to South Rock Island’s climate, homeowners will want to mitigate low efficiency, rot and water damage. We factored in local experience to reflect the ability of South Rock Island window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
