How Installing Energy-Efficient Windows in Holtsville Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here are more details about how upgrading your windows could help you:
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% when you install Energy Star certified windows. In Holtsville, that's about 307 pounds per year on average.
- Protect your investment: Upgrading your windows is an important part of maintaining your property and its real estate value, particularly if you have an older home.
- Save money on energy bills: Because energy-efficient windows reduce the amount of energy used to heat or cool your home, the switch can help you save about $437 annually on your energy bills in Holtsville.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
Estimated Cost of Window Replacement in Holtsville
Let's take a look at the cost of updating your windows and the types of services offered by installers.
How Much Do New Windows Cost?
According to our market research, the national average cost to replace a single window is about $600. However, window replacement costs can range from $200 to $1,200 per window. These numbers vary based on specific characteristics of your installation, including number of windows, size, material, type, the location of your home and more.
Keep in mind that energy-efficient windows may come at a higher price point, but Energy Star predicts the upgrade will save you between $101 and $583 per year when installing single-pane windows and between $27 and $197 per year when installing double-pane, clear glass windows. These savings vary based on your local climate, energy rates and individual home characteristics.
Something else that affects the total cost is the material you choose for your frame. Aluminum frames are typically the least pricey and are sturdy and relatively maintenance-free, but they offer poor insulation. On the other hand, wood frames are the most expensive because they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation as well and cost somewhere between the other two.
What Services do Window Installers Offer?
In regard to window installations, there are typically two kinds that your installer will offer: full-frame and pocket installations.
A full-frame installation is a replacement of the full window. This service involves removing the old window, the sill, and the exterior and interior trim. It also involves extra materials, like insulation and drip edges, which raise the overall cost of the project. It's also worth noting that it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. A pocket installation involves replacing a window without replacing the frame. This means instead of removing the whole unit and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.
Your window installer should be able to help you decide which type of installation you should get.

How We Choose the Best Window Installers in Holtsville
In our search to make your home improvements easier and more eco-friendly in Holtsville, EcoWatch evaluated many companies before landing on these. We've assessed the best window replacement companies in Holtsville mostly based on energy efficiency, as it's the most sustainable option and the best one for homeowners. Energy Star certified windows have been shown to lower electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is pretty self-explanatory, but we've chosen to highlight window installation companies that serve Holtsville so you can find a quality window installation company near you.
Work Quality
When selecting new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the type of window you choose. 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 patterns in recent online reviews to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across nearly every category, including professionalism, quality of installation, cost, quality of parts, warranty and more.
Cost
This one is a give-and-take: similar to other services, cheap window companies are not going to provide the highest quality service. On the other hand, we want to ensure we're highlighting companies that provide a wide 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 provide lengthy warranties for products, parts and labor 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.
Holtsville, NY Window Replacement FAQs
What is the typical cost to install new windows?
The average cost to install a single window can range from $450 to $650. There are a variety of factors that influence how much it costs, such as your property's location, how energy-efficient the windows are, local labor costs, the number of windows, styles and sizes of windows and the materials used in designing the windows.
Which kind of window is the best?
Generally, double-pane windows are more efficient than single-pane windows and windows that don't open will be more efficient than windows that do. To be sure you'll get the most energy-efficient windows, look for models with the blue Energy Star certification — that means they're certified energy-efficient by the U.S. Department of Energy.
What do window installation companies do?
Window installers go to your home to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
How long does it take to install windows?
Since a window takes about 30 minutes to install, about 16 windows can be installed in a typical 8-hour work day.
What time of year is a good time to replace my windows?
Replacement windows can be installed any time of the year, but warmer weather is typically better. Regardless of when you install them, the contractors will take steps to make sure that too much hot or cold air doesn't get into the home, so the temperature outside isn't necessarily a big factor. Most importantly, the weather should be dry.
