How Installing Energy-Efficient Windows in Mastic Saves You Money
There are quite a few benefits of switching to energy-efficient windows. A few reasons you may want to consider making the change are the following:
- Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its real estate value, particularly if your home is on the older side.
- Save money on electricity bills: The Department of Energy estimates that heat gained or lost via windows makes up about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help reduce that number, which helps you save some money on your bills.
- Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Mastic, that’s about 307 pounds per year on average.
- Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
Estimated Cost of Window Replacement in Mastic
Each window replacement company offers varying services and has varying price points depending on a few factors.
How Much Do New Windows Cost?
The national average cost to replace one window is about $600 but can range from $200 to $1,200. But costs will vary significantly depending on the quality of your products, the number of windows you need, your location and the current condition of your home. Many window companies also offer replacement door installations and other add-ons like shutters, baths, coating and more. These extra services will increase overall project costs.
It’s also worth bearing in mind that energy-efficient windows will typically cost more upfront, but Energy Star estimates that upgrading the windows on your Mastic home can mean an average energy savings of $236 to $319 per year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. The amount of money you’ll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.
How much your window installation costs will also vary based on the type of material you choose for the frames. Wood windows are usually the most expensive, though it depends on whether they are completely wood or clad with aluminum or vinyl. Fiberglass windows also tend to be a bit more expensive than vinyl, but they are more efficient.
What Services do Window Installers Offer?
In regard to window installations, there are generally two kinds that your installer will have: full-frame and pocket installations.
Full-frame installations involve replacing the full window, including the trim, sill and frame. Full-frame installations are necessary when you want to change the style of your windows or your window has noticeable deterioration. Because these installations are more involved, they will increase overall costs. A pocket installation involves replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.
Your window replacement company should be able to help you decide what’s best for your needs. In Mastic, the decision will mostly depend on how old your windows are and if there’s any moisture damage. Wood can decay if it’s not maintained properly over the years, so it’s a good idea to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Mastic
In our hunt to make your home improvements easier and more eco-friendly in Mastic, EcoWatch examined dozens of companies before deciding on these. We’ve evaluated the best window installation companies in Mastic primarily based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows have been shown to reduce your power bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each installer included in our guide to ensure its contractors are well-qualified and that the company has gotten tons of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another very important review factor. If the majority of customers don’t have positive things to say about their service from a certain installer, it won’t be featured on EcoWatch.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing providers’ prices, we gave higher points 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 with lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. Window installers that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
Mastic, NY Window Replacement FAQs
What is the average cost to install new windows in a home?
The average cost to install one window can range from $450 to $650. There are several factors that influence how much it costs, which include your property’s location, the number of windows, local labor costs, the materials used in designing the windows, styles and sizes of windows and how energy-efficient the windows are.
Which type of window is the best?
A window’s energy efficiency depends on a number of factors, including the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are typically the most energy-efficient and are certified by the U.S. Department of Energy.
What do window installation companies do?
Window installers go to your property to remove your old windows and replace them with new ones. Some providers install products distributed by other companies, whereas others install their own windows. The installer will also clean up after the installation.
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 replacing windows. Additionally, it shouldn’t be raining, as rain can make the installation more difficult.
How do you know it’s time to replace your windows?
Windows generally last around 20 to 30 years, but anytime you notice damage on your windows, it’s a good time to have them looked at by an expert to determine if they are in need of a repair or replacement.
