Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although environmentally friendly energy sources like wind and solar are important when it comes to lowering your carbon footprint, improving your house’s efficiency can also have a considerable impact on home energy conservation. Potential leaks or drafts can cut your home’s energy efficiency by up to 30%, according to the Department of Energy. In Central Islip, that’s about $215 a year that you could save on your energy bills after making the switch.

That’s also bad for the environment because the additional energy required by drafty windows increases your carbon footprint.

Efficient windows are of particular importance in Central Islip, 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 $215 per year.

Estimated Window Cost:
161 homeowners have requested a free estimate in the last 3 days.

Estimates will vary based on window dimensions and other unique factors to your home. Getting in touch with a local window installer is the best way to get an accurate cost estimate for your home.

How Installing Energy-Efficient Windows in Central Islip Saves You Money

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

  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing fading of your furniture, carpet and other valuables.
  • Save money on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of energy use in your home. Upgrading to energy-efficient windows can help lower that number, which helps you save more on your bills.
  • Decrease your carbon footprint: By using less energy once you upgrade to energy-efficient windows, you’ll also be lowering your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or leaky. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.

Estimated Cost of Window Replacement in Central Islip

Windows come in different shapes, styles and purposes, so costs and services will vary greatly depending on your project. Below, we describe the typical cost and services that you can get from window installation companies.

How Much Do New Windows Cost?

On average, Central Islip homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at about $600. But prices vary considerably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door installations, which have a higher price tag.

It’s important to keep in mind that windows with higher efficiency may cost more initially but can save you hundreds of dollars by decreasing your energy bills. Investing in certified energy-efficient windows can save Central Islip homeowners $215+ a year when replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames are the least expensive. They’re sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are somewhat expensive and offer good insulation. Composite frames made from wood fibers encased in plastic also offer good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

There are typically two types of window installation services: full-frame and pocket installations.

Full-frame installations entail replacing the total window, including the trim, frame and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has considerable rot. Because these installations are more involved, they will raise the total cost. Pocket installations (or retrofits) entail replacing a window within its existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.

Your window installation company can help you decide which type of installation you need.

How We Choose the Best Window Installers in Central Islip

In our search to find the most reliable, eco-friendly window installers in Central Islip, the EcoWatch Reviews team landed on the above companies as the top window installation companies in the city. We have decided to review the best window installers in Central Islip mainly based on energy efficiency, as it’s what’s best for the environment and for you as a homeowner. Energy Star certified windows can reduce your 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 a wide variety of states and cities so you can find the right window installation company near you.

Work Quality

When installing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand of window you choose. 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 online reviews to find the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including cost, quality of parts, warranty, professionalism, quality of installation and more.

Cost

This one is a give-and-take: similar to most services, cheap window companies won’t always provide the most quality service. On the other hand, we want to make sure we’re highlighting companies that provide a variety of price and financing options so they’re accessible to most homeowners.

Warranty

As discussed previously, windows are a sizable investment, so you’ll want to make sure that investment is well protected. Window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of Central Islip’s climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Central Islip window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Central Islip, NY Window Replacement FAQs

How much does a window install cost?

The average cost of installing a single window ranges between $450 and $650. There are a variety of factors that influence how much it costs, which include the materials used in designing the windows, local labor costs, how energy-efficient the windows are, styles and sizes of windows, the number of windows and your property’s location.

Which kind of window is the best?

Generally, double-pane windows will be more efficient than single-pane windows and windows that do not open will be more efficient than windows that do. If you want to be sure you’ll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they’re certified energy-efficient by the U.S. Department of Energy.

What services do window installation companies do?

Window installation companies will do the entire process — from replacing old windows with brand-new ones to cleaning up afterward. Additionally, a lot of companies offer window manufacturing, customization and repairs.

When is the best time of year to replace windows?

Even though you can install windows any time of year, warmer weather is often better for installing replacement windows. Additionally, the weather should be dry, since rain can make the installation harder.
