Why you can trust EcoWatch
Although renewable energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your house's energy efficiency can also have a big impact on home energy conservation. Potential leaks or drafts can reduce your home's energy efficiency by up to 30%, according to the Department of Energy. In Charlotte, that's nearly $346 per year that you could save on your electricity bills after making the switch.
That's also bad for the environment because the extra energy required by drafty windows increases your carbon footprint.
Unlike other sites, EcoWatch ranks window installation companies based on energy efficiency while also taking into consideration cost, customer satisfaction and service area.

How Installing Energy-Efficient Windows in Charlotte Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more ways upgrading your windows could benefit you:
- More efficient energy use in your household: In Charlotte where the summers can be pretty hot, energy-efficient windows lower how much cool air is lost through your windows, which makes it easier to keep your house cool.
- Save money on energy bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
- Reduce your carbon footprint: In Charlotte, you can lower your indirect greenhouse gas emissions by about 345 pounds per year after you switch to energy-efficient windows.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, especially if your home is on the older side.
Estimated Cost of Window Replacement in Charlotte
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?
On average, homeowners in Charlotte can expect that most replacement window installations will cost between $250 and $1,200, with the average cost sitting at around $600. These figures are based on the specifics of your installation, including type, number of windows, size, material, the location of your home and more.
With windows, efficiency is the most important factor for many homeowners. Efficient windows may cost more initially, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Charlotte homeowners $346+ per year after replacing single-pane windows.
Something else that affects the total cost is the material you select 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 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?
In regard to window replacements, in general there are two types that your installer will have: full-frame and pocket installations.
Full-frame installations are usually recommended when you want a new style or your window has significant rot or deterioration. With this service, your installers will replace the entire window, including the frame, sill and trim. Pocket installations (or retrofits) entail installing a new window within its existing frame, which makes pocket installations more simple and affordable. However, if the frame has any damage or rot, you should opt for a full-frame installation instead.
If you're still trying to decide which kind of installation you should get, you can consult with your provider and get their recommendation. The choice mostly is influenced by how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Charlotte
EcoWatch reviews differ from most reviews because we examine these companies through a sustainability lens. Along with energy efficiency, we assessed each installer and assigned rankings based on the following methodology:
Service Area
Since this is a guide for Charlotte, we only included companies that cover 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
When selecting new windows, the quality and variety of services often plays just as important of a role in overall efficiency 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 factor in workmanship as reflected in customer feedback.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don't have nice things to say about their experience with a certain installer, it won't be featured on EcoWatch.
Cost
Cheaper windows certainly don't mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing providers' prices, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
Protecting your investment in new windows is important. That's why window installation companies that provide lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Charlotte's climate, homeowners need to be wary of water damage, low efficiency and rot. We factored in local experience to reflect the ability of Charlotte window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Charlotte, NC Window Replacement FAQs
How much should window installation cost?
The typical cost of installing a single window ranges from $450 to $650. There are a variety of factors that affect how much it costs, such as your property's location, local labor costs, how energy-efficient the windows are, the number of windows, styles and sizes of windows and the materials used in designing the windows.
What kind of window is the best for energy efficiency?
A window's energy efficiency is influenced by several factors, such as 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 installers do?
Window installers go to your property to remove your old windows and replace them with new ones. Some companies install products made by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is finished.
What time of year should I replace my windows?
Although you can install windows any time of year, warmer weather is usually better for replacing windows. In addition, it shouldn't be raining, since rain can make the installation harder.
Should I replace all my windows at once?
If you want to get more efficient windows and save money on energy costs, replacing all your windows at the same time is the only way to gain that benefit. On the other hand, if you have just one or two windows that are broken or drafty, you can replace just those.
