How Installing Energy-Efficient Windows in Greenwich Saves You Money

Switching to energy-efficient windows can improve the comfort of your home and help you save on electricity bills. Here are more details about how switching out your windows could benefit you:

• 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 Older homes tend to have windows that are outdated, leaky or maybe even damaged in some way. Upgrading your windows could help increase the value of your property if you decide to sell.
• Protect your valuables from fading: When you switch to energy-efficient windows that have 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 electricity bills: Since energy-efficient windows decrease how much energy you need to heat or cool your home, they can help you save about $441 annually on your energy bills in Greenwich.
• Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Greenwich, that’s about 147 pounds per year on average.

Estimated Cost of Window Replacement in Greenwich

Windows come in varying styles, purposes and shapes, so costs and services will differ considerably based on your project. Below, we go over the average cost and services that you’ll find from window installers.

How Much Do New Windows Cost?

On average, homeowners in Greenwich can anticipate that most replacement window installations will range from $250 to $1,200, with the most common installations sitting at around $600. How much it will cost is based on several factors, such as material, type, the location of your home, size, number of windows and more.

Whether or not you want 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.

Something else that influences the overall cost is the material of the frame you pick. Aluminum frames are generally the least expensive and are sturdy and light, but they provide poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

The first step when planning a window installation is to clarify whether you should get a full-frame or pocket installation.

A full-frame installation replaces the total window, such as the sill, frame, trim and the window panes. As this type of installation requires more time, it will be more expensive than a pocket installation. A pocket installation entails installing a new window without replacing the frame. So, instead of removing the whole window and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you’re not sure which kind of window installation service you should get, your installer can help you out. Typically, the decision depends on factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Greenwich

In our hunt to find the most reliable, eco-friendly window installers in Greenwich, EcoWatch chose the above companies as the best window installation companies in the city. Along with energy efficiency, we analyzed each installer and assigned rankings using the following methodology:

Service Area

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

Work Quality

When selecting new windows, the quality and breadth of services often plays just as important of a role in insulation and performance as the brand 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

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

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs low when possible. When analyzing the prices of providers, we awarded 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 that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

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