Why you can trust EcoWatch
Although renewable energy sources like wind and solar are important when it comes to decreasing your carbon footprint, improving your house’s efficiency can also have a big impact on home energy conservation. Drafty or leaky windows can make your AC or heater work extra hard in the summer or winter.
Replacement windows improve your home’s insulation, not only making you more comfortable during the summer and winter, but also saving you some money and helping the environment.
Efficient windows are of particular importance in Hempstead, where the temperature varies throughout the year. According to Energy Star, making the switch to energy-efficient windows can save the average homeowner up to $283 per year.

How Installing Energy-Efficient Windows in Hempstead Saves You Money
When you upgrade to energy-efficient windows, you may see some perks, such as:
- Save on power bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% because you use less energy.
- Decrease your carbon footprint: Because energy-efficient windows improve the insulation in your home, you can lower your indirect greenhouse gas emissions by about 12%, according to Energy Star.
- Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your home if you decide to sell.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Hempstead
When considering window installation, each company offers varying services and costs. Let’s go over some typical costs and services.
How Much Do New Windows Cost?
Typically, Hempstead homeowners can expect their window installations to range from $250 to $1,200. The most common installations sit at around $600. How much it will cost varies depending on several factors, like type, material, the location of your home, number of windows, size and more.
Bear in mind that energy-efficient windows may have a higher price, 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 a year when replacing double-pane, clear glass windows. Your savings will vary depending on your local climate, energy rates and individual home characteristics.
We advise getting free quotes from several window companies to find the one that works best for you.
What Services do Window Installers Offer?
There are typically two kinds of window replacement services: full-frame and pocket installations.
A full-frame installation replaces the complete window, including the sill, frame, trim and the window panes. As this kind of installation is more involved, it will cost more than a pocket installation. A pocket installation entails replacing a window within the existing frame, which is usually less expensive than a full-frame installation.
Your window installation company will be able to help you decide what’s best for your needs. In Hempstead, the decision will mostly be based on the age of your home and if there’s any damage. Wood can decay if not properly maintained over the years, so it’s a good idea to have a professional examine your frames and window sills.

How We Choose the Best Window Installers in Hempstead
In our hunt to find the most reliable, eco-friendly window installers in Hempstead, the EcoWatch team landed on the above companies as the best window installation companies in the city. We’ve evaluated the best window replacement companies in Hempstead mostly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can lower power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve Hempstead so you can find the best window installation company near you.
Work Quality
When selecting new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the type of window 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 determine the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including quality of parts, cost, quality of installation, professionalism, warranty and more.
Cost
Cheaper windows don’t necessarily 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 scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
As discussed previously, windows are a sizable 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
Last but not least, we like to see companies that have been in the industry for quite some time. Window installers that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.
Hempstead, NY Window Replacement FAQs
How much does window installation cost?
The national average cost of installing a window is around $600 but can range from $200 to $1,200, depending on a few different factors. The price is often influenced by the size of the window, the type and material of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
What kind of window is the most energy-efficient?
A window’s energy efficiency is influenced by a variety of factors, including the quality of the installation and the kind of window. Look for Energy Star Certified windows — these are often the most energy-efficient since they are certified 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 companies install products manufactured by other companies, whereas others install their own windows. The installer will also clean up after the installation is complete.
When is the best time of year to replace windows?
Although you can install windows any time of year, warmer weather is often better for installing replacement windows. In addition, the weather should be dry, as rain can make the installation more difficult.
How long does window installation usually take?
Each window takes around 30 minutes to install based on the type of window. However, the window installation can take two days or more if you have a lot of windows that have to be installed.
