How Installing Energy-Efficient Windows in Greenfield Saves You Money

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

• Decrease your carbon footprint: Reducing how much energy you use also lowers your carbon emissions. You could reduce it by 497 pounds per year on average.
• Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Updating your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.
• Save on electricity bills: The Department of Energy estimates that heat gained or lost through windows makes up about 25-30% of household energy use. Switching to energy-efficient windows can help lower that amount, which helps you save some money on your bills.
• Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Greenfield

Let’s take a look at the cost of window installation and the types of services you may need for your home.

How Much Do New Windows Cost?

Though the average cost of replacing a single window is about $600, it can range from $200 to $1,200. This is due to the fact that the cost of window installations are based on a variety of factors specific to your home, including the size, material and number of windows you need to install, as well as where your property is located.

With windows, efficiency is the most important factor for most homeowners. Efficient windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the winter — they can give you decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Greenfield homeowners $426+ per year after replacing single-pane windows.

We advise requesting free quotes from multiple window installation companies to find the one that works best for your budget.

What Services do Window Installers Offer?

In general, there are two kinds of window replacement services companies offer: full-frame and pocket installations.

Full-frame installations involve replacing the full window — the sill, frame, trim and all. These are typically done when you want a different style for your windows or when it has significant deterioration. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations more simple and affordable. However, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

Your window installation company will be able to recommend the best type for your project. In Greenfield, the choice will mostly be influenced by how much damage there is currently and the age of your existing frames.
