- Save on power bills: After you upgrade to energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll use less energy to heat or cool your house.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its value, especially if your home is on the older side.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% once you install Energy Star certified windows. In Kannapolis, that’s about 345 pounds per year on average.
Estimated Cost of Window Replacement in Kannapolis
When looking into window installation, each company provides different services and costs. Let’s look at some average costs and services.
How Much Do New Windows Cost?
Although the typical cost of replacing a single window is around $600, it can range from $200 to $1,200. This is due to the fact that window installations are based on several factors specific to your home, like the size, material and number of windows you need to replace, as well as the location of your property.
Whether or not you pick 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 $347 a year on your energy bills in Kannapolis.
How much your window installation costs will also vary based on the type of window material you choose for the frames. Wood windows are usually the most expensive, but it depends on whether they are solid wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
The first step of an installation is to think about whether you should get a full-frame or pocket installation.
Full-frame installations involve replacing the total window, including the frame, sill and trim. Full-frame installations are necessary when you want a new style or your window has significant damage or rot. Because these installations are more involved, they will raise the total cost. A pocket installation involves replacing a window within the existing frame, which is usually cheaper than a full-frame installation.
If you’re not sure which kind of window installation service you should get, your installer should be able to help you out. Generally, the choice depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Kannapolis
The EcoWatch Reviews team differs from other reviewers because we assess these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and assigned rankings using the following methodology:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installation companies that serve Kannapolis so you can find the right window installation company near you.
Work Quality
When choosing new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand you get. 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 trends in recent customer feedback to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including quality of installation, professionalism, cost, warranty, quality of parts and more.
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 providers’ prices, we gave higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that have 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 experience earn higher rankings by our standards. We like to see at least ten years of experience.
Kannapolis, NC Window Replacement FAQs
What is the average cost to install windows in a home?
The typical cost of replacing a window ranges between $450 and $650.

Generally, double-pane windows are more efficient than single-pane windows and windows that don’t open are more efficient than windows that do.
