How Installing Energy-Efficient Windows in Knightdale Saves You Money
When you upgrade to energy-efficient windows, you may see some benefits, such as:
- Save money on energy bills: Because energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save around $360 annually on your energy bills in Knightdale.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Keeping your windows up to date is an important part of maintaining your property and its real estate value.
- Reduce your carbon footprint: By using less energy once you switch to Energy Star certified windows, you'll also be decreasing your carbon dioxide emissions by about 12%, according to Energy Star.
Estimated Cost of Window Replacement in Knightdale
Each window replacement company offers varying services and has varying prices based on a few 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. These figures are based on the specifics of your installation, including size, number of windows, material, type, the location of your home and more.
Whether or not you want energy-efficient windows is another factor that will affect the cost. These will typically cost more than other windows, but on the other hand, you can save about $360 a year on your energy bills in Knightdale.
We advise requesting free quotes from several window installers to find the one that works best for you.
What Services do Window Installers Offer?
There are generally two kinds of window installation services: full-frame and pocket installations.
A full-frame installation is a total window replacement. This service involves removing the old window, the windowsill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which increase the total cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. A pocket installation entails replacing a window without replacing the frame. This means instead of taking out the whole unit and reinstalling it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installation company should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Knightdale
EcoWatch reviews are different from other reviews because we're examining these companies through a sustainability lens. We've evaluated the best window installation companies in Knightdale mostly based on their energy efficient offerings, as it's what's best for the environment and for you as a homeowner. Energy Star certified windows can reduce your power 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 Knightdale, we gave more points to companies that provide services to the city. There are certainly reputable providers that didn't make the list because they wouldn't be able to serve homeowners in Knightdale.
Work Quality
We're certain that you're looking for a company to do a great job installing windows. We've vetted each installer in our guide to make sure its contractors are well-qualified and that the company has received lots of positive customer feedback to vouch for its service.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If most customers don't have positive things to say about their service from a certain window installation company, it won't be featured on EcoWatch.
Cost
This one is a give-and-take: as with other services, cheap window companies may not provide the most quality service. On the other hand, we want to make sure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a hefty investment, so you'll want to make sure that investment is well protected. Window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have been in the industry for a while. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Knightdale, NC Window Replacement FAQs
How much does window installation cost?
The typical cost of installing a single window can range from $450 to $650. There are a variety of factors that affect the price, which include styles and sizes of windows, local labor costs, how energy-efficient the windows are, the number of windows, your property's location and the materials used in designing the windows.
Which type of window should I get?
A window's energy efficiency is affected by a number of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.
Can you replace your own windows?
Even though you can install your own windows, doing so is time-consuming and requires a lot of experience with home improvement projects. Hiring a professional can help guarantee that the installation is done properly and that you won't have to spend the time and effort to do it yourself.
What time of year should I replace my windows?
Replacement windows can be installed during any season, but warmer weather is typically better. No matter when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your home, so the temperature outside isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.
Should I replace my windows all at the same time?
If you're upgrading your windows to save on your energy bills, replacing all of your windows together is the only way to see a noticeable difference. However, if you have only one or two windows that are broken or drafty, you can replace just those.
