How Installing Energy-Efficient Windows in Darien Saves You Money
By switching to energy-efficient windows, you and your family can benefit in several ways, such as:
- Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes tend to have windows that are outdated, drafty or maybe even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
- Save on energy bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you need less energy.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
- Reduce your carbon footprint: Reducing the amount of energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 65 pounds.
Estimated Cost of Window Replacement in Darien
When looking into window installation, each company provides different services and prices. Let's look at some typical costs and services.
How Much Do New Windows Cost?
According to our market research, the average cost of replacing a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. How much it will cost you is based on several factors, such as material, type, the location of your home, size, number of windows and more.
It's also worth bearing in mind that energy-efficient windows will almost always cost more initially, but Energy Star estimates that upgrading the windows on your Darien home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Costs will also vary based on the material of your frame. Aluminum frames cost the least. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They're also aesthetically pleasing and offer decent insulation for your home.
What Services do Window Installers Offer?
The first question to ask yourself when getting new windows is: Should you get a full-frame installation or a pocket installation?
Full-frame installations are usually recommended when you want a new style or your window has significant deterioration. With this service, your professionals will replace the complete window, including the trim, frame and sill. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and will be less expensive, but you can't do this kind of installment if you have any pre-existing rot or water damage.
Your window installation company can recommend the best type for your project. In Darien, the decision will mostly depend on the efficiency of your home and the age and condition of your existing frames.

How We Choose the Best Window Installers in Darien
In our search to make your home improvements easier and more eco-friendly in Darien, EcoWatch landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we reviewed window companies all across the state and ranked them based on the following methodology:
Service Area
Since this is a guide for Darien, we only included companies that provide services to the city. There are other reputable providers that didn't make our list because they wouldn't be able to serve homeowners in Darien.
Work Quality
When it comes to new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand of window you choose. 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 trends in recent online reviews to find the companies with the most consistent 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 warranty, cost, quality of installation, quality of parts, professionalism and more.
Cost
This one is a give-and-take: as with other services, cheap window companies won't always provide the highest quality service. On the other hand, we want to make sure we're highlighting companies that provide a wide range of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a serious investment, so you'll want to make sure that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Darien's climate, homeowners will want to mitigate low efficiency, water damage and rot. We factored in local experience to reflect the ability of Darien window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Darien, NY Window Replacement FAQs
How much does a window install cost?
The typical cost to install one window can range between $450 and $650. There are a variety of factors that influence how much it costs, including your property's location, local labor costs, the materials used in designing the windows, the number of windows, how energy-efficient the windows are and styles and sizes of windows.
What type of window is the best for energy efficiency?
A window's energy efficiency is influenced by 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.
What do window installation companies do?
Window installation professionals travel to your home to remove your old windows and replace them with new ones. Some companies install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is done.
Should I replace all my windows at once?
If you're upgrading your windows to get more efficient windows, replacing all of the windows at once is the only way to gain that benefit. However, if you have only a few windows that are damaged or drafty, you can replace just those.
