How Installing Energy-Efficient Windows in Mastic Saves You Money

Switching to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here's more information on how upgrading your windows could help you:

  • Protect your investment: If your home is on the older side, your windows are most likely in need of replacement. Upgrading your windows can make your home more comfortable and also help raise the value of your property if you decide to sell.
  • Save money on power bills: Switching to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
  • Decrease your carbon footprint: You can reduce your carbon footprint by about 12% once you install Energy Star certified windows. In Mastic, that’s about 307 pounds per year on average.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Mastic

Windows come in all shapes and sizes, so costs and services will vary considerably. Here are the typical costs and services that you’ll find from the average window installation company.

How Much Do New Windows Cost?

On average, homeowners in Mastic can anticipate that most replacement window installations will range from $250 to $1,200, with the average cost sitting at about $600. These numbers are based on the specifics of your installation, including type, number of windows, the location of your home, material, size and more.

It’s also worth noting that energy-efficient windows will typically cost more upfront, but Energy Star predicts that upgrading the windows on your Mastic home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 a year for double-pane windows. How much you’ll save by installing energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Costs will also vary depending on the material of your frame. Aluminum frames are the least expensive. They’re sturdy, light and maintenance-free, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

When considering window replacements, there are generally two kinds that your provider 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 windowsill, and the exterior and interior trim. It also involves extra materials, such as insulation and drip edges, which raise the total cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are simpler and won’t carry as large a bill, but you can’t do this kind of installment if you have any pre-existing rot or water damage.

Your window installation company should be able to help you figure out what’s best for your needs. In Mastic, the decision will mostly be based on the age of your home and if there’s any moisture damage. Wood can decay if it’s not properly maintained over the years, so it’s a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Mastic

In our search to make your home improvements easier and more eco-friendly in Mastic, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. We’ve reviewed the top window installers in Mastic mostly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows can cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:

Service Area

Because this is a guide for Mastic, we paid more attention to companies that cover the city. There are other reputable providers that didn’t make the cut because they wouldn’t be able to serve homeowners in Mastic.

Work Quality

When picking new windows, the quality and range of services can often play just as important of a role in insulation and performance as the type of window you opt for. 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 super important review factor is customer feedback. If the majority of customers don’t have good things to say about their service from a certain company, you won’t see it featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers would like to keep costs low when possible. When analyzing providers’ prices, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a serious investment, so you’ll want to be certain that investment is well protected. Window installation companies that offer 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 quite some time. Window installers that have more 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 typical cost to install new windows in a home?

The average cost of replacing a window can range between $450 and $650. There are several factors that influence how much it costs, such as your property’s location, styles and sizes of windows, how energy-efficient the windows are, the number of windows, the materials used in designing the windows and local labor costs.

What type of window is the best for energy efficiency?

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 usually the most energy-efficient since they are certified by the U.S. Department of Energy.

What services do window installation companies offer?

Window installers visit your home to remove your old windows and replace them with new ones. Some providers install products made by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation is done.

How do you know it’s time to replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, then they probably need to be replaced. Other than that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may be in need of replacement.
