How Installing Energy-Efficient Windows in Knightdale Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on power bills. Here's more information on how switching out your windows could help you:
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
- Decrease your carbon footprint: In Knightdale, you can lower your indirect greenhouse gas emissions by about 345 pounds per year once you upgrade to energy-efficient windows.
- 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 damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of energy use in your home. Installing energy-efficient windows can help decrease that number, which helps you save some money on your bills.
Estimated Cost of Window Replacement in Knightdale
Each window installation company provides varying services and has varying costs based on several factors.
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. How much it will cost is based on several factors, including material, type, the location of your home, size, number of windows and more.
It’s also worth keeping in mind that energy-efficient windows will cost more upfront, but Energy Star predicts that upgrading the windows on your Knightdale home translates to an average energy savings of $236 to $319 a 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 upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
The cost of your window installation will also vary based on the kind of window material you choose for the frames. Wood windows are generally the most expensive, though it depends on whether they are completely 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?
Generally, there are two types of window replacement services companies provide: full-frame and pocket installations.
Full-frame installations involve replacing the full window, including the frame, trim and sill. Full-frame installations are necessary when you want to change the style of your windows or your window has considerable damage. These installations are more involved and will raise the total cost. Pocket installations (also known as retrofits) are when you replace a window within its existing frame. Pocket installations are simpler and will be less expensive, but you can’t do this type of installment if you have any pre-existing rot or water damage.
Your window installation company can advise you on the best type for your project. In Knightdale, the choice will mostly be influenced by the efficiency of your home and the condition of your existing frames.

How We Choose the Best Window Installers in Knightdale
EcoWatch is different from other reviewers since we examine these companies through a sustainability lens. Along with energy efficiency, we reviewed each installer and ranked them based on the following methodology:
Service Area
Since this is a guide for Knightdale, we only included companies that provide services to the city. There are certainly other reputable providers that didn’t make our list because of the low odds that they would serve the average homeowner in Knightdale.
Work Quality
When picking new windows, the quality and breadth of services can often play just as important of a role in insulation and performance as the brand of window you choose. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If most customers don’t have positive things to say about their experience with a certain window installation company, you won’t see it featured on EcoWatch.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important. That’s why window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have a good track record in the industry. 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 should window installation cost?
The average cost to install a window can range between $450 and $650. There are a variety of factors that affect the cost, such as styles and sizes of windows, the number of windows, your property’s location, how energy-efficient the windows are, the materials used in designing the windows and local labor costs.
What are the types of windows?
There are various kinds of windows you can get for your house, such as bay windows, double-hung and single-hung windows, awning windows, slider windows, picture windows, casement windows and transom windows.
When do I need to use a window installation company?
Unless you have experience with home improvement projects and have the tools needed to replace your own windows, we recommend hiring the pros. The window installation process is quite involved and can take anywhere from four to six hours for a single window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer alternative.
When is the best time of year to replace windows?
Replacement windows can be installed during any season, but autumn might be best. Regardless of 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 most important is that the weather should be dry.
Should I replace all my windows at the same time?
If your windows are greater than 20 years old, it’s most likely time to replace all of them. At that point, they are often less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
