Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although clean energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house's energy efficiency can also have a big impact on home energy conservation. If your windows are outdated or drafty, you could be sending 25-30% of your house's heat or cool air out of them.

Thankfully, helping you save energy with upgraded windows also aligns with our goals of reducing energy usage for the environment.

Efficient windows are especially important in Danbury, where the temperature varies throughout the year. According to Energy Star, switching to energy-efficient windows can save the average homeowner up to $441 per year.

How Installing Energy-Efficient Windows in Danbury Saves You Money

By switching to energy-efficient windows, you can enjoy several benefits, including:

  • More efficient energy use in your household: In Danbury where the winters can be very cold, energy-efficient windows reduce the amount of heat that is lost through your windows, making it easier to keep your house warm.
  • Protect your investment: When you have an older home, your windows could also be outdated or leaky. Upgrading your windows is an important part of maintaining your property and its real estate value.
  • 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: Upgrading to energy-efficient windows reduces your energy bills by about 12% because you use less energy.

Estimated Cost of Window Replacement in Danbury

Windows come in various shapes, styles and purposes, so costs and services will differ considerably based on your project. Below, we detail the typical cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

Typically, Danbury homeowners can anticipate their window installations to range from $250 to $1,200. The most common installations sit at around $600. But prices 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 will add extra costs to your project.

With windows, efficiency is the most important factor for many homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can give you many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Danbury homeowners $441+ per year after replacing single-pane windows.

Getting free quotes from multiple companies is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

In regard to window replacements, there are generally two kinds that your installer will offer: full-frame and pocket installations.

Full-frame installations are usually done when you want a new style or your window has significant rot. With this service, your installers will replace the complete window, including the frame, trim and sill. A pocket installation entails replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.

Your window installation company can help you choose which type of installation you need.

How We Choose the Best Window Installers in Danbury

In our search to find the most reliable, eco-friendly window installers in Danbury, the EcoWatch team landed on the above companies as the top window installation companies in the city. Along with energy efficiency, we assessed several window installers in Danbury and ranked them using the following methodology:

Service Area

This one is pretty self-explanatory, but we've chosen to highlight window installers that serve Danbury so you can find the right window installation company near you.

Work Quality

When picking new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the type 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 consistent customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including warranty, quality of installation, professionalism, cost, quality of parts and more.

Cost

This one is a give-and-take: similar to most services, cheap window companies may not provide the most quality service. Still, we want to ensure 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. For that reason, window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a good track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Danbury, CT Window Replacement FAQs

How much should a window install cost?

The national average cost of replacing a window is around $600 but can range from $200 to $1,200, based on several factors. The price is generally influenced by the location of your property, the type and material of the window and the size 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?

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 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 have home repair skills and have all of the necessary tools to replace your own windows, we recommend hiring the pros. The window installation process is complicated 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 company is a faster, more efficient and much safer option.

How long does it usually take to install windows?

Because a window takes about 30 minutes to install, around 16 windows can be installed during an 8-hour work day.
