How Installing Energy-Efficient Windows in Westport Saves You Money
Upgrading to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here's more information on how switching out your windows could help you:
- Save on power bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% because you'll use less energy to heat or cool your house.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
- Decrease your carbon footprint: By using less energy once switching to energy-efficient windows, you'll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.
Estimated Cost of Window Replacement in Westport
Each window replacement company provides various services and has different price points depending on a few factors.
How Much Do New Windows Cost?
Although the average to install a single window is around $600, it can range anywhere from $200 to $1,200. But costs will vary significantly depending on your location, the current condition of your home, the quality of your products and the number of windows you need. Many window companies also offer replacement door installations and other add-ons like baths, shutters, coating and more. These extra services will increase your overall project costs.
Whether or not you opt for energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $333 a year on your energy bills in Westport.
How much your window installation costs will also vary depending on the type of window material you choose for the frames. Wood windows are typically the most expensive, but it depends if they are 100% 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?
The first step when considering a window installation is to figure out whether you need a full-frame or pocket installation.
Full-frame installations are usually done when you want to change the style of your windows or your window has significant rot. With this service, your installers will replace the entire window, including the sill, frame and trim. Pocket installations are simpler and won't cost as much because they entail simply replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.
Your window installation company can help you figure out which type of installation you need.

How We Choose the Best Window Installers in Westport
The EcoWatch Reviews team differs from other reviewers because we look at these companies through a sustainability lens. Along with energy efficiency, we assessed 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 a wide variety of states and cities so you can find the right window installation company near you.
Work Quality
When selecting new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand 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
Customer feedback is another super important review factor. If most customers don't have nice things to say about their experience with a certain installer, you won't see it featured on EcoWatch.
Cost
Cheaper windows don't necessarily mean better windows, but we know many of our readers try to keep costs low when 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. For that reason, window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Due to Westport's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Westport window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Westport, NC Window Replacement FAQs
How much does a window install cost?
The national average cost of replacing a single window is about $600 but can range from $200 to $1,200, based on a variety of factors. The price is typically dependent on the size of the window, the type and material of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
Which type of window is the best?
A window's energy efficiency is affected by a number of factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified by the U.S. Department of Energy.
When do I need to use a window installation company?
Unless you have experience with home improvement projects and have all of the necessary tools to replace your own windows, we recommend hiring a professional installer. The window installation process is complicated and can take anywhere from four to six hours for a single window. Although it's tempting to try to save some money by doing it yourself, hiring a company is a faster, more efficient and much safer alternative.
When is the best time of year to replace windows?
Replacement windows can be installed any time of the year, 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 the home, so the temperature outside doesn't necessarily matter that much. What's most important is that the weather should be dry.
Should I replace my windows all at the same time?
If your windows are more than 20 years old, it's probably time to replace all of them. By that point, they are typically less efficient, leakier and/or more damaged than new windows. Doing your windows all at once will involve less paperwork and less stress.
