How Installing Energy-Efficient Windows in Cornelius Saves You Money
By upgrading to energy-efficient windows, you and your family can enjoy several benefits, including:
- Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its value.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, reducing fading of your furniture, carpet and other valuables.
- Decrease your carbon footprint: By using less energy once switching to Energy Star certified windows, you'll also be reducing your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Save money on energy bills: Switching to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
Estimated Cost of Window Replacement in Cornelius
Each window installer offers various services and has varying prices depending on several factors.
How Much Do New Windows Cost?
The typical cost to replace one window is about $600 but can range from $200 to $1,200. How much it will cost varies based on several factors, including number of windows, type, size, the location of your home, material and more.
Keep in mind that energy-efficient windows may cost more upfront, but Energy Star estimates 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 replace double-pane, clear glass windows. Your exact savings will vary based on your local climate, energy rates and individual home characteristics.
We recommend getting free quotes from multiple window installers to find the one that works best for your budget.
What Services do Window Installers Offer?
The first step when considering a replacement is to decide whether you need a full-frame or pocket installation.
Full-frame installations require replacing the full window — the sill, frame, trim and all. These are typically done when you want to change the style of your window or when it has significant rot or deterioration. Full-frame installations require more time and labor and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler 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.
If you're still debating which kind of installation you should get, you can talk to your provider and get their recommendation. The decision mostly is influenced by how old the frames are and if there's any damage present.

How We Choose the Best Window Installers in Cornelius
In our search to find the most reliable, eco-friendly window installers in Cornelius, the EcoWatch Reviews team examined many companies before settling on these. Along with energy efficiency, we evaluated window companies all across the state and ranked them using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve the Cornelius area so you can find the best window installation company near you.
Work Quality
When selecting new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand of window you opt for. 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 patterns in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might 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, professionalism, quality of parts and more.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs as low as possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than "cheaper" services.
Warranty
As discussed, windows are a hefty investment, so you'll want to make sure that investment is well protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for quite some time. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Cornelius, NC Window Replacement FAQs
How much does a window install cost?
The average cost to install one window can range between $450 and $650. There are several factors that influence how much it costs, which include the materials used in designing the windows, styles and sizes of windows, local labor costs, your property's location, the number of windows and how energy-efficient the windows are.
What type of window is the best for energy efficiency?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you'll get the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.
Can you replace your own windows?
Even though it is possible to install your own windows, doing so requires a lot of time and handiness. Hiring a professional can help guarantee that the job is done properly and that you can avoid spending the time and effort of doing it yourself.
How long does it generally take to install windows?
Since the average installation time is 30 minutes per window, around 16 windows can be installed in a typical 8-hour work day.
How often should you replace windows?
Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.
