How Installing Energy-Efficient Windows in Westport Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here's more information on how upgrading your windows could help you:
- Reduce your carbon footprint: By using less energy once switching to Energy Star certified windows, you'll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
- Protect your valuables: The low-emissivity coatings on many Energy Star certified windows help reduce damage from the sun's UV rays to your floors, carpets and furniture.
- Save on power bills: Once you switch to energy-efficient windows, you can see a reduction in your bills by about 12% since you'll need less energy to heat or cool your house.
- 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 Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Westport
Each window installation company provides various services and has varying price points depending on several factors.
How Much Do New Windows Cost?
According to our research, the average cost of replacing a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. How much it will cost is based on several factors, including the location of your home, number of windows, size, material, type and more.
With windows, efficiency is the most important factor for most homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — particularly if you live in a hot climate — they can give you decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save Westport homeowners $349+ a year after replacing single-pane windows.
The cost of your window installation will also vary based on the type of material you choose for the frames. Wood windows are typically the most expensive, though it depends if they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are shown to be more efficient.
What Services do Window Installers Offer?
The first thing to ask yourself when planning on installing new windows is: Do you want a full-frame installation or a pocket installation?
A full-frame installation is a replacement of the total window. This service involves removing the old window, the windowsill, and the exterior and interior trim. It also involves extra materials, including insulation and drip edges, which raise 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. Pocket installations are simpler and won't cost as much because they involve merely replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.
If you're still trying to decide which kind of installation to get, you can ask your provider and get their recommendation. The decision mostly is influenced by the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Westport
In our hunt to find the most reliable, eco-friendly window installers in Westport, the EcoWatch team assessed dozens of companies before settling on these. We've reviewed the best window installation companies in Westport mostly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve Westport so you can find the best window installation company near you.
Work Quality
When installing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand of window you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed patterns in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction might be the most important factor, as it reflects the quality of services across nearly every category, including quality of parts, warranty, professionalism, quality of installation, cost 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
As discussed, windows are a considerable 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
Because of Westport's climate, homeowners will want to mitigate 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 should window installation cost?
The typical cost to install one window can range from $450 to $650. There are several factors that affect how much it costs, such as how energy-efficient the windows are, the number of windows, your property's location, local labor costs, the materials used in designing the windows and styles and sizes of windows.
Which type of window should I get?
Generally, double-pane windows are more efficient than single-pane windows and windows that don't open are more efficient than windows that do. If you want to be sure you'll have the most energy-efficient windows, look for models with the blue Energy Star certification — they're certified energy-efficient by the U.S. Department of Energy.
Do you really have to use a window installation company?
Unless you're handy and have the tools needed to replace your own windows, we recommend hiring a professional. The window installation process is complex 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 company is a faster, more efficient and much safer alternative.
What time of year is the best time to replace my windows?
Replacement windows can be installed at any time, 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 more important than the temperature is that the weather should be dry.
Should I replace all my windows at once?
If your windows are greater than 20 years old, you probably need to replace all of them. By that point, they are often less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less time.
