How Installing Energy-Efficient Windows in Cornelius Saves You Money

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here's more information on how switching out your windows could help you:

  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent damage from the sun's UV rays to your floors, carpets and furniture.
  • Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
  • Reduce your carbon footprint: By using less energy once you upgrade to Energy Star certified windows, you’ll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
  • Save on energy bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of residential energy use. Upgrading to energy-efficient windows can help reduce that number, which helps you save more on your bills.

Estimated Cost of Window Replacement in Cornelius

When researching window installation, each company offers varying services and prices. Let’s take a look at some typical costs and services.

How Much Do New Windows Cost?

According to our market research, the average cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. But costs differ remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations and replacements, which will add extra costs to your project.

Keep in mind that energy-efficient windows may come at a higher price point, but Energy Star predicts the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.

Costs will also vary depending on the material you want for your window frames. Aluminum frames cost the least. They’re sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

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

Full-frame installations entail replacing the full window, including the frame, trim and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has considerable damage. Because these installations are more involved, they will raise the overall cost. A pocket installation entails installing a new window without replacing the frame. This means instead of tearing out the whole unit and reinstalling it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

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

How We Choose the Best Window Installers in Cornelius

In our search to make your home improvements easier and more eco-friendly in Cornelius, the EcoWatch team examined many companies before landing on these. Along with energy efficiency, we assessed each installer and assigned rankings using the following methodology:

Service Area

Since this is a guide for Cornelius, we paid more attention to companies that cover the city. There are certainly other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Cornelius.

Work Quality

When picking new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the type of window you get. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent customer feedback to determine the companies with the highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including professionalism, warranty, quality of installation, cost, quality of parts and more.

Cost

This one is a give-and-take: as with most services, cheap window installers may not provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that offer a wide range of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed, windows are a substantial investment, so you’ll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Cornelius, NC Window Replacement FAQs

How much should window installation cost?

The typical cost to install one window can range between $450 and $650. There are several factors that affect the cost, including local labor costs, the materials used in designing the windows, how energy-efficient the windows are, the number of windows, styles and sizes of windows and your property’s location.

What type of window is the best for energy efficiency?

Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. To be sure you’re getting the most energy-efficient windows, look for models with the blue Energy Star certification — they’re certified energy-efficient by the U.S. Department of Energy.

When do I have to use a window installation company?

You should hire a window installation company whenever you want to replace your windows. Installing windows is a complicated process that can be difficult to do on your own, so it’s best left to the professionals.

How long does window installation generally take?

Since the average installation time of a window is 30 minutes, around 16 windows can be installed in an 8-hour work day.
