How Installing Energy-Efficient Windows in Greenfield Saves You Money
By switching to energy-efficient windows, you and your family can enjoy several benefits, including:
- Reduce your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 117 pounds.
- Save on energy bills: Installing energy-efficient windows reduces your energy bills by about 12% because you use less energy.
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.
- Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Greenfield
When researching window installation, each company offers varying services and costs. Let's go over some average costs and services.
How Much Do New Windows Cost?
Typically, Greenfield homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at about $600. These figures are based on specific characteristics of your installation, such as type, number of windows, size, material, the location of your home and more.
It's also worth bearing in mind that energy-efficient windows will usually cost more upfront, but Energy Star estimates that switching out the windows on your Greenfield home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. The amount of money you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
Requesting free quotes from several installers is the best way to find out which one will work best for your budget.
What Services do Window Installers Offer?
Generally, there are two kinds of window replacement services companies offer: full-frame and pocket installations.
A full-frame installation replaces the full window, including the windowsill, frame, trim and the window panes. As this kind of installation requires more time and labor, it will cost more than a pocket installation. A pocket installation involves replacing a window without replacing the frame. This means instead of taking out the whole unit and reinstalling it, the installer will just put the replacement window (also called a retrofit or insert window) into the frame.
If you're still trying to decide which kind of installation you need, you can ask your installer and get their recommendation. The decision mostly is influenced by how old the frames are and if there's any damage.

How We Choose the Best Window Installers in Greenfield
The EcoWatch Reviews team differs from most reviewers since we look at these companies through a sustainability lens. Along with energy efficiency, we reviewed window companies all across the state and assigned rankings using the following methodology:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installers that serve Greenfield so you can find the right window installation company near you.
Work Quality
When it comes to new windows, the quality and range of services often plays just as important of a role in insulation and performance as the brand you choose. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.
Customer Reviews
Another self-explanatory yet very important review factor is customer feedback. If the majority of customers don't have good feedback about their service from a certain window installation company, you won't see it featured on EcoWatch.
Cost
This one is a give-and-take: as with most services, cheap window installers won't always provide the highest quality service. Still, we want to make sure we're highlighting companies that offer a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed, windows are a substantial investment, so you'll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Because of Greenfield's climate, homeowners will want to mitigate water damage, low efficiency and rot. We factored in local experience to reflect the ability of Greenfield window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.
Greenfield, CA Window Replacement FAQs
How much should window installation cost?
The national average cost to install a window is about $600 but can range from $200 to $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, bear in mind that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.
What are the most common kinds of replacement windows?
There are several different kinds of windows you can get for your house, including casement windows, transom windows, picture windows, slider windows, bay windows, awning windows and double-hung and single-hung windows.
What services do window installation companies provide?
Window installation professionals will do the entire process — from replacing old windows with new ones to cleaning up after the installation. Additionally, some companies offer window manufacturing, customization and repairs.
How long does it take to install windows?
Each window takes about 30 minutes to install based 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.
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 home, so the temperature outside isn't necessarily a big factor. What's more important than the temperature is that the weather should be dry.
