How Installing Energy-Efficient Windows in Fayetteville Saves You Money

Switching 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 upgrading your windows could help you:

  • 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 Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
  • Reduce your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 345 pounds per year on average.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
  • Save money on electricity bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% because you use less energy.

Estimated Cost of Window Replacement in Fayetteville

Windows come in varying shapes, purposes and styles, so costs and services will differ tremendously based on several factors. Below, we describe the typical cost and services that you can get from window replacement companies.

How Much Do New Windows Cost?

The average cost to install a single window is about $600 but can range from $200 to $1,200. This is because of the fact that window installations depend on a variety of factors specific to your home, including the size, material and number of windows you need to install, as well as the location of your property.

It’s also worth keeping in mind that energy-efficient windows will almost always cost more upfront, but Energy Star estimates that switching out the windows on your Fayetteville home translates to 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. The amount of money you’ll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Something else that influences the total cost is the material you pick for your frame. Aluminum frames are generally the least expensive 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 offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

When it comes to window installations, there are generally two kinds that your provider will have: full-frame and pocket installations.

Full-frame installations entail replacing the full 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 these installations are more involved, they will increase overall costs. Pocket installations are simpler and won’t cost as much because they involve simply replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.

Your window installation company will be able to recommend the best type for your project. In Fayetteville, the decision will mostly be influenced by how much damage there is currently and the age and condition of your existing frames.

How We Choose the Best Window Installers in Fayetteville

In our search to find the most reliable, eco-friendly window installers in Fayetteville, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we analyzed several window installers in Fayetteville and assigned rankings using 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 a quality 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 installer included in our guide to ensure its technicians are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.

Customer Reviews

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

Cost

This one is a give-and-take: as with other services, cheap window companies are not going to provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that provide a wide range 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 installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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

Fayetteville, NC Window Replacement FAQs

How much does window installation cost?

The average cost of replacing a window ranges from $450 to $650. There are a variety of factors that influence how much it costs, such as your property’s location, how energy-efficient the windows are, the number of windows, the materials used in designing the windows, local labor costs and styles and sizes of windows.

What kind of window is the best for energy efficiency?

A window’s energy efficiency is affected by several factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.

What do window installation companies do?

Window installation professionals travel to your home to remove your old windows and replace them with new ones. Some companies install products distributed by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.

When is the best time of year to replace windows?

Replacement windows can be installed at any time, but warmer weather is typically better. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into your house, so the temperature outside isn’t necessarily a big factor. What’s most important is that the weather should be dry.
