Why you can trust EcoWatch
A guide on the best window installation companies in Darien may not seem like the most riveting article on EcoWatch, but trust us, windows have more of an impact on your life than you might think. Potential leaks or drafts can cut your home's energy efficiency by up to 30%, according to the Department of Energy. In Darien, that's about $365 per year that you could save on your electricity bills after making the switch.
That's also bad for the environment because the extra energy required by outdated windows increases your carbon footprint.
Because windows have such a big impact on your home, picking the right company for you is a big choice to make. That's why the EcoWatch team has curated this list of the top window installation companies, so you can more easily make an informed decision.

How Installing Energy-Efficient Windows in Darien Saves You Money
When you upgrade to energy-efficient windows, you may see a few benefits, such as:
- Better temperature control in your home: Living in a warm city like Darien can often mean needing your AC to keep your house cool. Energy-efficient windows can cut back on how much cool air is lost through your windows when cooling your home.
- More efficient energy use in your home: Because the winters can get cold in Darien, homeowners often depend on their heater during that time. Energy-efficient windows reduce how much heat is lost through your windows, which makes it easier to keep your house warm.
- Decrease your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 65 pounds.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Darien
Each window installer provides various services and has different costs depending on several factors.
How Much Do New Windows Cost?
The national average cost to install a single window is about $600 but can range from $200 to $1,200. But costs vary considerably based on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window companies also provide door installations, which carry a higher price tag.
With windows, efficiency is one of the most important factors for many homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — especially during the winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Darien homeowners $365+ per year after replacing single-pane windows.
Something else that affects the total cost is the material of the frame you choose. Aluminum frames are typically the least expensive and are sturdy and light, but they offer poor insulation. On the other hand, wood frames cost the most, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.
What Services do Window Installers Offer?
When it comes to window installations, in general there are two types that your installer will offer: full-frame and pocket installations.
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 can also involve additional materials, like insulation and drip edges, which increase the total cost of the project. It's also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation means replacing a window without removing the complete frame, which tends to be cheaper than a full-frame installation.
If you're unsure which window installation service you should get, your installer should be able to help you out. Generally, the choice depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Darien
EcoWatch differs from most reviewers because we examine these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and ranked them based on the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installers that serve the Darien area so you can find the best window installation company near you.
Work Quality
When picking new windows, the quality and range of services often plays just as important of a role in insulation 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 may be the most important factor, as it reflects the quality of services across nearly every category, including professionalism, cost, quality of parts, warranty, quality of installation and more.
Cost
This one is a give-and-take: similar to most services, cheap window installers won't always provide the highest quality service. Still, we want to make sure we're highlighting companies that offer a range of price and financing options so they're accessible to most homeowners.
Warranty
Protecting your investment in new windows is important to many homeowners. That's why window installation companies that give you lengthy warranties for products, parts and labor 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 years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
Darien, NY Window Replacement FAQs
How much does window installation cost?
The national average cost of replacing a single window is about $600 but can range from $200 to $1,200, based on several factors. The price is often influenced by the location of your property, the size of the window and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.
What type of window is the best for energy efficiency?
A window's energy efficiency depends on several factors, including 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.
Do you really have to use a window installation company?
Unless you have home repair skills and have all the tools you need to replace your own windows, we recommend hiring a professional. The process of installing windows 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 company is a faster, more efficient and safer option.
How long does window installation typically take?
Because the average installation time of a window is 30 minutes, about 16 windows can be installed during an 8-hour work day.
When is the best time of year to replace windows?
Replacement windows can be installed any time of the year, but autumn might be the best season. 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.
