How Installing Energy-Efficient Windows in Kings Mountain Saves You Money
Energy-efficient windows can provide benefits in several ways. Here are some reasons you may want to take the plunge and make the switch:
- Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
- Save on energy bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
- Reduce your carbon footprint: In Kings Mountain, you can reduce your indirect greenhouse gas emissions by about 345 pounds per year after you switch to energy-efficient windows.
- Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes usually have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Kings Mountain
Let’s take a look at the cost of window installation and the types of services offered by installers.
How Much Do New Windows Cost?
The typical cost to install a single window is about $600 but can range from $200 to $1,200. This is because of the fact that the cost of window installations depend on several factors specific to your home, like the size, material and number of windows you need to install, as well as where your property is located.
Bear in mind that energy-efficient windows may cost more, but Energy Star predicts the upgrade will save you between $101 and $583 a year when you replace single-pane windows and between $27 and $197 a year when you install double-pane, clear glass windows. These savings vary depending on your local climate, energy rates and individual home characteristics.
The cost of your window installation will also vary depending on the kind of window material you choose for the frames. Wood windows are typically the most expensive, though it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first step of a replacement is to decide whether you should get a full-frame or pocket installation.
A full-frame installation replaces the entire window, such as the windowsill, frame, trim and the window panes. As this type of installation requires more time, it will be more expensive than a pocket installation. Pocket installations (also known as retrofits) are when you replace a window while leaving the existing frame. Pocket installations are on the simpler end and won’t cost as much, but you can’t do this type of installment if you have any pre-existing rot or water damage.
Your window replacement company should be able to help you choose what’s best for your needs. In Kings Mountain, the decision will mostly depend on how old your windows are and if there’s any moisture damage. Wood can decay if it’s not properly maintained over the years, so it’s good to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Kings Mountain
In our search to find the most reliable, eco-friendly window installers in Kings Mountain, the EcoWatch team evaluated many companies before landing on these. We have decided to review the top window installation companies in Kings Mountain primarily based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows have been shown to reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
Because this is a guide for Kings Mountain, we only included companies that cover the city. There are certainly reputable providers that didn’t make the cut because of the low odds that they would serve the average homeowner in Kings Mountain.
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 featured on this list to make sure its contractors are well-qualified and that the company has gotten plenty of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including quality of installation, cost, warranty, quality of parts, professionalism and more.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers’ prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important to many homeowners. That’s why window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Kings Mountain’s climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of Kings Mountain window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Kings Mountain, NC Window Replacement FAQs
What is the typical cost to install new windows?
The average cost of replacing a window ranges from $450 to $650. There are many factors that influence the cost, including the materials used in designing the windows, your property’s location, how energy-efficient the windows are, styles and sizes of windows, the number of windows and local labor costs.
What are the different types of windows?
The most common kinds of windows for homes are slider windows, transom windows, awning windows, casement windows, picture windows, bay windows and double-hung and single-hung windows.
Can I install my own windows?
If you’re handy and have experience with similar home improvement projects, you may be able to install your own windows. However, if you don’t have the time or experience, we don’t recommend it.
What time of year is a good time to replace my windows?
While you can install windows any time of year, warmer weather is often better for replacing windows. In addition, the weather should be dry, because rain can make the installation more difficult.
