How Installing Energy-Efficient Windows in Darien Saves You Money
Energy-efficient windows can benefit you in more than one way. Here are a few reasons you may want to take the plunge and make the switch:
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, particularly if you have an older home.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Decrease your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by 147 pounds per year on average.
- Save money on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of residential energy use. Installing energy-efficient models can help reduce how much energy is used in your home, therefore saving you about 12% more on your bills.
Estimated Cost of Window Replacement in Darien
Windows come in different purposes, styles and shapes, so costs and services will differ remarkably based on your project. Below, we go over the average cost and services that you can get from window replacement companies.
How Much Do New Windows Cost?
According to our market research, the national average cost of installing a single window is around $600. However, window replacement costs can range from $200 to $1,200 for each window. How much it will cost depends on several factors, like number of windows, the location of your home, type, size, material and more.
Whether or not you want 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 $441 a year on your energy bills in Darien.
Costs will also vary depending on the material you choose for your window frames. Aluminum frames have the lowest price. They’re sturdy, light and maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also provide 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?
Generally, there are two types of window installation services companies offer: full-frame and pocket installations.
A full-frame installation replaces the complete window, such as the windowsill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation means replacing a window without removing the complete frame, which is usually cheaper than a full-frame installation.
If you’re hiring a reputable window installation company, your company can recommend the best type for your project. In Darien, the decision will mostly depend on how much damage there is currently and the age and condition of your existing frames.

How We Choose the Best Window Installers in Darien
EcoWatch reviews are different from most reviews because we examine these companies through a sustainability lens. Along with energy efficiency, we evaluated each installer and ranked them based on the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve Darien so you can find a quality window installation company near you.
Work Quality
When choosing new windows, the quality and variety of services can often play just as important of a role in insulation and performance as the brand of window you opt for. We do rate window installers higher if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet super important review factor is customer feedback. If the majority of customers don’t have good things to say about their experience with a certain company, it won’t be featured on EcoWatch.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers’ prices, we awarded higher points to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed, windows are a substantial investment, so you’ll want to make sure that investment is protected. Window installation companies that offer lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Because of Darien’s climate, homeowners need to be wary of 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, CT Window Replacement FAQs
How much should a window install cost?
The typical cost of replacing a window can range between $450 and $650. There are a variety of factors that affect how much it costs, including your property’s location, local labor costs, the number of windows, the materials used in designing the windows, how energy-efficient the windows are and styles and sizes of windows.
What type of window is the best for energy efficiency?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you’ll get the most energy-efficient windows, look for models with the blue Energy Star certification attached to them — this means they’re certified energy-efficient by the U.S. Department of Energy.
When do I need to use a window installation company?
Unless you’re handy and have the time needed to replace your own windows, we recommend hiring the pros. The process of installing windows is quite involved and can take anywhere from four to six hours for one window. Although it’s tempting to try to do it yourself to save money, hiring a professional is a faster, more efficient and much safer option.
How do you know it’s time to replace your windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they probably need to be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to operate, they may be in need of replacement.
How long does it usually take to install windows?
Since a window takes about 30 minutes to install, around 16 windows can be installed in a typical 8-hour work day.
