How Installing Energy-Efficient Windows in Greenwich Saves You Money

There are several perks of upgrading to energy-efficient windows. Some reasons you may want to consider making the change include the following:

  • Save money on power bills: Because energy-efficient windows decrease the amount of energy used to heat or cool your home, the switch can help you save about $441 annually on your energy bills in Greenwich.
  • Protect your investment: When you have an older home, your windows could also be outdated or leaky.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.
  • Reduce your carbon footprint: In Greenwich, you can reduce your indirect greenhouse gas emissions by about 147 pounds per year once you switch to energy-efficient windows.
  • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less due to their ability to filter out damaging UV rays.

Estimated Cost of Window Replacement in Greenwich

Windows come in different shapes and sizes, so costs and services will vary greatly. Here are the typical costs and services that you can find from the average window installation company.

How Much Do New Windows Cost?

The typical cost to install a single window is about $600 but can range from $200 to $1,200. How much it will cost varies based on several factors, including the location of your home, size, number of windows, material, type and more.

Whether or not you want to install energy-efficient windows is another factor that will affect 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 Greenwich.

Asking for free quotes from multiple providers is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

There are generally two types of window installation services: full-frame and pocket installations.

Full-frame installations are necessary when you want a new style or your window has significant rot or deterioration. With this service, your installers will replace the complete window, including the sill, trim and frame. A pocket installation entails replacing a window without replacing the frame. So, instead of tearing out the whole window and reinstalling it, the window installer will just put the replacement window (also called a retrofit or insert window) into the frame.

If you're still debating which type of installation you should get, you can ask your installer and get their recommendation. The decision mostly is influenced by the age of your window frames and if there's any damage present.

How We Choose the Best Window Installers in Greenwich

EcoWatch is different from other reviewers because we assess these companies through a sustainability lens. We have evaluated the best window installation companies in Greenwich mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows have been shown to cut your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Since this is a guide for Greenwich, we gave more points to companies that serve the city. There are certainly reputable providers that didn't make the cut because they wouldn't be able to serve homeowners in Greenwich.

Work Quality

When it comes to new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand you get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the most consistent customer satisfaction. Customer satisfaction may be the most important factor, as it reflects the quality of services across most other categories, including quality of installation, cost, warranty, quality of parts, professionalism and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs as low as possible. When analyzing the prices of providers, we gave higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed, windows are a hefty investment, so you'll want to be certain that investment is protected. Window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for a while. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

Greenwich, CT Window Replacement FAQs

What is the typical cost to replace windows?

The national average cost to replace one window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is often influenced by the size of the window, the location of your property 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 kind of window is the best for energy efficiency?

A window's energy efficiency depends on several factors, such as the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are usually the most energy-efficient since they are certified by the U.S. Department of Energy.

Do I really have to use a window installation company?

Unless you have home repair skills and have the time to replace your own windows, we recommend hiring a professional. The window installation process is complicated and can take anywhere from four to six hours for a single window. Although it's tempting to try to save money by doing it yourself, hiring a company is a faster, more efficient and much safer option.

How long does window installation typically take?

Since the average installation time is 30 minutes per window, around 16 windows can be installed during an 8-hour work day.

Should I replace all my windows at the same time?

If you're upgrading your windows because of energy-efficiency, replacing all of the windows at once is the only way to see a noticeable difference. On the other hand, if you have only one or two windows that are broken or drafty, you can replace just those.
