How Installing Energy-Efficient Windows in Darien Saves You Money
There are several benefits of upgrading to energy-efficient windows. A few reasons you may want to consider making the switch are the following:
- Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
- Save money on power bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of energy use in your home. Switching to energy-efficient windows can help reduce that number, which helps you save some money on your bills.
- Decrease your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Darien, that’s about 449 pounds per year on average.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
Estimated Cost of Window Replacement in Darien
Windows come in different shapes, purposes and styles, 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 installation companies.
How Much Do New Windows Cost?
Generally, Darien homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at around $600. How much it will cost varies based on several factors, such as the location of your home, size, type, material, number of windows and more.
It’s important to remember that windows with higher efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in Energy Star certified windows can save Darien homeowners $300+ a year when replacing single-pane windows.
Costs will also vary based on the material of your frame. Aluminum frames cost the least. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide 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 provide decent insulation for your home.
What Services do Window Installers Offer?
There are typically two types of window replacement services: full-frame and pocket installations.
A full-frame installation is a replacement of the total window. This service involves taking out the old window, the sill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which raise the total cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. A pocket installation entails replacing a window within the existing frame. This means instead of tearing out the whole window and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.
Your window installer should be able to help you choose which type of installation you should get.

How We Choose the Best Window Installers in Darien
EcoWatch reviews are different from most reviews because we’re examining these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and assigned rankings based on the following methodology:
Service Area
Since this is a guide for Darien, we gave more points to companies that cover the city. There are certainly other reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in Darien.
Work Quality
When choosing new windows, the quality and breadth of services can often play 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. Customer satisfaction may be the most important factor, as it reflects the quality of services across nearly every category, including quality of installation, professionalism, quality of parts, warranty, cost and more.
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 the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies with 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 rot, low efficiency and water damage. 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, IL Window Replacement FAQs
What is the average cost to install new windows in a home?
The national average cost to install one window is around $600 but can range between $200 and $1,200, based on several factors. The price is usually influenced by the type and material of the window, the location of your property and the size of the window. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the most common kinds of replacement windows?
There are several different types of windows you can get for your home, such as awning windows, picture windows, casement windows, transom windows, bay windows, double-hung and single-hung windows and slider windows.
When do I need to use a window installation company?
You should use a window installation company whenever you want new windows. Installing windows is a complex process that can be difficult to do on your own, so it’s best left to the professionals.
When is the best time of year to replace windows?
Replacement windows can be installed at any time, but autumn might be the best season. No matter when you install them, the contractors will take steps to make sure that too much hot or cold air doesn’t get into your house, so the temperature outside doesn’t necessarily matter that much. Most importantly, the weather should be dry.
How long does it typically take to install windows?
Each window takes about 30 minutes to install depending on the kind of window. However, the window installation can be a two-day job — or more — if you need to have a lot of windows installed.
