Why you can trust EcoWatch
Although green energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your home’s efficiency can also have a big impact on home energy conservation. The Department of Energy estimates that heat gained or lost through traditional or outdated windows could be responsible for nearly 30% of heating and cooling use. In Charlotte, where the energy bills are an average of $41 per month, that’s almost $$147 per year wasted.
Installing efficient windows on your home can help you save money each month on your electric bills — and you can help the environment as well.
Efficient windows are of particular importance in Charlotte, where summers are long and hot. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $346 each year.

How Installing Energy-Efficient Windows in Charlotte Saves You Money
When you switch to energy-efficient windows, you may see some perks, 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 Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help increase the value of your property if you decide to sell.
- Save on electricity bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Upgrading to energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Reduce your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Charlotte, that’s about 345 pounds per year on average.
Estimated Cost of Window Replacement in Charlotte
Let’s go over the cost of updating your windows and the types of services offered by installers.
How Much Do New Windows Cost?
According to our research, the typical cost of installing a single window is about $600. However, window replacement costs can range from $200 to $1,200 for each window. How much it will cost varies based on several factors, including number of windows, material, size, type, the location of your home and more.
Whether or not you pick energy-efficient windows is another factor that will affect the cost. These will usually cost more than other windows, but on the other hand, you can save about $346 a year on your energy bills in Charlotte.
The cost of your window installation will also vary depending on the type of material you choose for the frames. Wood windows are usually the most expensive, but it depends on whether 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 question to ask yourself when planning to replace your windows is: Should you get a full-frame installation or a pocket installation?
Full-frame installations entail replacing the complete window, including the trim, sill and frame. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable damage. These installations are more involved and will raise the total cost. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.
If you’re not sure which kind of window installation service you need, your installer can advise you. Generally, the decision is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Charlotte
In our hunt to make your home improvements easier and more eco-friendly in Charlotte, the EcoWatch team examined many companies before landing on these. We’ve reviewed the best window replacement companies in Charlotte mostly based on their energy efficient offerings, as it’s the most sustainable option and the best one for homeowners. Energy-efficient windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
Since this is a guide for Charlotte, we gave more points to companies that serve the city. There are certainly other reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Charlotte.
Work Quality
We’re willing to bet that you’re looking for professionals who do a great job installing windows. We’ve vetted each company in our guide to make sure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don’t have good feedback about their service from a certain window installation company, you won’t see it featured on EcoWatch.
Cost
This one is a give-and-take: similar to other services, cheap window companies may not provide the highest quality service. Still, we want to ensure we’re highlighting companies that provide a 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 with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Charlotte’s climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of Charlotte window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Charlotte, NC Window Replacement FAQs
What is the average cost to install new windows in a home?
The average cost to replace a single window ranges from $450 to $650. There are several factors that influence how much it costs, including local labor costs, the materials used in designing the windows, the number of windows, styles and sizes of windows, how energy-efficient the windows are and your property’s location.
Which type of window should I get?
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’ll have the most energy-efficient windows, look for models that have the blue Energy Star certification — that means they’re certified energy-efficient by the U.S. Department of Energy.
Can I replace my own windows?
If you’re handy and have experience with installing a replacement window, it’s possible to install your own windows. But if you don’t have the time or know-how, we recommend hiring a professional.
When is the best time of year to replace windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. Regardless of 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 doesn’t necessarily matter that much. What’s more important than the temperature is that the weather should be dry.
