How Installing Energy-Efficient Windows in New Castle 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 help you:
- Save on energy bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% because you'll require less energy to heat or cool your home.
- Reduce your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can reduce your carbon footprint by about 12%, according to Energy Star.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.
Estimated Cost of Window Replacement in New Castle
Windows come in different shapes, purposes and styles, so costs and services will differ considerably depending on your project. Below, we describe the typical cost and services that you'll find from window replacement companies.
How Much Do New Windows Cost?
The national average cost to replace one window is about $600 but can range from $200 to $1,200. This is because the cost of window installations are based 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.
It's also worth keeping in mind that energy-efficient windows will almost always cost more initially, but Energy Star estimates that switching out the windows on your New Castle home can mean 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 installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Costs will also vary based on the material you choose for your window frames. Aluminum frames are the least expensive. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.
What Services do Window Installers Offer?
In general, there are two types of window installation services companies provide: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. It involves taking out the old window, the windowsill, and the exterior and interior trim. It can also involve other materials, including insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails replacing a window within the existing frame, which is generally less expensive than a full-frame installation.
Your window installer should be able to help you figure out which type of installation you need.

How We Choose the Best Window Installers in New Castle
The EcoWatch Reviews team differs from other reviewers since we evaluate these companies through a sustainability lens. Along with energy efficiency, we evaluated window companies all across the state and ranked them based on the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve New Castle so you can find the best window installation company near you.
Work Quality
When picking 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 consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including professionalism, quality of parts, warranty, cost, quality of installation and more.
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
As discussed, windows are a significant investment, so you'll want to make sure that investment is protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a good track record in the industry. Window installation companies that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
New Castle, CO Window Replacement FAQs
How much should window installation cost?
The national average cost of replacing a single window is about $600 but can range between $200 and $1,200, based on a variety of factors. The price is typically dependent on the location of your property, the type and material of the window and the size of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What kind of window is the best for energy efficiency?
Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you'll get the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — this means they're certified energy-efficient by the U.S. Department of Energy.
When do I need to use a window installation company?
You should use a window installation professional whenever you want new windows. Installing windows is a involved process that can take a lot of time, so it's best handled by the professionals.
How often do you need to replace your windows?
Windows generally last about 20 to 30 years, but anytime you see damage on your windows, it's a good time to have them checked by an expert to determine if they need any repairs or replacements.
Should I replace my windows all at the same time?
If you're upgrading your windows to save on your energy bills, replacing all your windows at the same time is the only way to gain that benefit. However, if you have just a few windows that are damaged or leaky, you can replace just those.
