How Installing Energy-Efficient Windows in Cary Saves You Money
By switching to energy-efficient windows, you can take advantage of several benefits, such as:
- Protect your investment: When you have an older home, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its value.
- Save money on power bills: After you install energy-efficient windows, you can expect a reduction in your bills by about 12% since you’ll use less energy to heat or cool your house.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Cary, that’s about 345 pounds per year on average.
Estimated Cost of Window Replacement in Cary
Windows come in various shapes and sizes, so costs and services will vary tremendously. Here are the typical costs and the primary services that you’ll find from window installation companies.
How Much Do New Windows Cost?
Typically, homeowners in Cary can anticipate that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at about $600. But costs will differ significantly based on the current condition of your home, your location, the number of windows you need and the quality of your products. Many window companies also offer door installations and other add-ons like coating, shutters, baths and more. These extra services will increase overall project costs.
Whether or not you opt for energy-efficient windows is another factor that will influence the cost. These will usually cost more than other windows, but on the other hand, you can save about $360 a year on your energy bills in Cary.
Something else that influences the overall cost is the material of the frame you select. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
The first step when considering a window replacement is to decide whether you should get a full-frame or pocket installation.
A full-frame installation replaces the complete window, such as the sill, frame, trim and the window panes. As this kind of installation requires more time and labor, it will cost more than a pocket installation. Pocket installations are on the simpler end and won’t carry as large a bill, as they entail merely replacing the window within its existing frame. But if the frame has any damage or rot, you may need a full-frame installation instead.
Your window replacement company should be able to help you understand what’s best for your needs. In Cary, the decision will mostly depend on how old your windows are and if there’s any moisture damage. Wood can decay if not properly maintained over the years, so it’s a good idea to have a professional assess your frames and window sills.

How We Choose the Best Window Installers in Cary
In our search to make your home improvements easier and more eco-friendly in Cary, the EcoWatch team evaluated dozens of companies before deciding on these. We have evaluated the best window installers in Cary mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve Cary so you can find a quality window installation company near you.
Work Quality
When picking new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the type of window you choose. 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 determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it indicates the quality of services across nearly every category, including cost, professionalism, quality of parts, warranty, quality of installation and more.
Cost
This one is a give-and-take: similar to most services, cheap window installers are not going to provide the highest quality service. Still, we want to make sure we’re highlighting companies that offer a variety of price and financing options so they’re accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Cary’s climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Cary window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.
Cary, NC Window Replacement FAQs
How much should window installation cost?
The national average cost of installing a window is about $600 but can range from $200 to $1,200, based on a variety of factors. The price is typically influenced by the size of the window, the type and material of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What type of window is the most energy-efficient?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. To be sure you’ll have the most energy-efficient windows, look for models with the blue Energy Star certification — this means they’re certified energy-efficient by the U.S. Department of Energy.
Can you replace your own windows?
If you’re handy and know how to replace a window, it’s possible to install your own windows. However, if you don’t have the time or experience, we don’t recommend trying it.
When is the best time of year to replace windows?
While you can install windows any time of year, warmer weather is generally better for replacing windows. Additionally, it shouldn’t be raining, since rain can make the installation harder.
Should I replace my windows all at the same time?
If you’re upgrading your windows because of energy-efficiency, replacing all of the windows at the same time is the only way to see a noticeable difference. However, if you have only one or two windows that are damaged or drafty, you can replace just those.
