How Installing Energy-Efficient Windows in Knightdale Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are some reasons you may want to make the switch:
- More efficient energy usage in your home: In Knightdale where the summers can get pretty hot, energy-efficient windows decrease how much cool air is lost through your windows, which makes it easier to keep your house cool.
- 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.
- Reduce your carbon footprint: In Knightdale, you can reduce your indirect greenhouse gas emissions by about 345 pounds per year after you upgrade to energy-efficient windows.
- Save money on energy bills: Once you install 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.
Estimated Cost of Window Replacement in Knightdale
Each window installation company provides varying services and has different 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. How much it will cost varies depending on several factors, including type, material, size, the location of your home, number of windows and more.
It's also worth noting that energy-efficient windows will usually cost more upfront, but Energy Star estimates that upgrading the windows on your Knightdale home can mean an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you'll save by switching to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
Something else that affects the total cost is the material of the frame you pick. Aluminum frames are usually the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and provide decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
Generally, there are two types of window installation services companies offer: full-frame and pocket installations.
A full-frame installation is a replacement of the total window. It involves removing the old window, the sill, 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 surrounding the window after a full-frame installation. A pocket installation entails replacing a window without taking out the complete frame, which is generally less expensive than a full-frame installation.
Your window installation company will be able to help you decide what's best for your needs. In Knightdale, the decision will mostly be based on the age of your home and if there's any damage. Wood can decay if it's not maintained properly over the years, so it's a good idea to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Knightdale
In our search to find the most reliable, eco-friendly window installers in Knightdale, EcoWatch evaluated many companies before deciding on these. We've assessed the best window installers in Knightdale mainly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy-efficient windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve the Knightdale area so you can find the right window installation company near you.
Work Quality
We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each company featured on this list to ensure its contractors are well-qualified and that the company has gotten a lot of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don't have positive things to say about their experience with a certain company, you won't see it featured on EcoWatch.
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
Protecting your investment in new windows is important. That's why 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 a good track record in the industry. Window installers that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.
