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

By switching to energy-efficient windows, you and your family can benefit in several ways, such as:

  • Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Upgrading your windows could help increase the value of your home if you decide to sell.
  • Save money on energy bills: According to the Department of Energy, heat gained or lost through windows makes up around 25-30% of residential energy use. Switching to energy-efficient models can help reduce that number, therefore saving you about 12% more on your bills.
  • Decrease your carbon footprint: Decreasing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by 307 pounds per year on average.
  • Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.

Estimated Cost of Window Replacement in East Islip

Let's go over the cost of installing new windows and the kinds of services you may need for your home.

How Much Do New Windows Cost?

According to our research, the average cost to replace a single window is about $600. However, window installation costs can range from $200 to $1,200 for each window. But costs differ remarkably based 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 and replacements, which will make your project cost more.

It's important to note that windows with higher efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save East Islip homeowners $437+ a year when replacing single-pane windows.

Costs will also vary based on the material of your frame. Aluminum frames cost the least. They're sturdy, light and easy to maintain, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made with 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?

When it comes to window installations, in general there are two types that your installer will have: full-frame and pocket installations.

A full-frame installation replaces the entire window, including the windowsill, frame, trim and the window panes. Because this type of installation requires more time and labor, it will be more expensive than a pocket installation. A pocket installation means replacing a window without removing the entire frame, which is generally cheaper than a full-frame installation.

If you're unsure which window installation service you should get, your installer can advise you. In general, the decision depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in East Islip

In our hunt to find the most reliable, eco-friendly window installers in East Islip, the EcoWatch Reviews team chose the above companies as the best window installation companies in the city. We have evaluated the top window replacement companies in East Islip mostly based on energy efficiency, as it's what's best for the environment and for you as a homeowner. Energy-efficient 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 installers that serve the East Islip area so you can find a quality window installation company near you.

Work Quality

When it comes to new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand of window you get. 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 patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it reflects the quality of services across most other categories, including quality of installation, warranty, professionalism, quality of parts, cost and more.

Cost

Cheaper windows certainly don't mean better windows, but we know many of our readers want to keep costs low when 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, windows are a significant investment, so you'll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have been in the industry for a while. Window installation companies that have more experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.

East Islip, NY Window Replacement FAQs

What is the typical cost to install new windows?

The national average cost to replace a window is around $600 but can range from $200 to $1,200, depending on several factors. The price is typically dependent on the size of the window, the location of your property and the type and material of the window. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.

Which kind of window is the best?

A window's energy efficiency is affected by several factors, such as 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 since they are certified by the U.S. Department of Energy.

Do you really have to use a window installation company?

You should hire a window installation professional whenever you want to upgrade your windows. Installing windows is a complex process that can be difficult to do on your own, so it's best handled by the professionals.

When is the best time of year to replace windows?

While you can install windows any time of year, warmer weather is usually better for installing replacement windows. In addition, it shouldn't be raining, since rain can make the installation harder.

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. Apart from that, if your windows have damage anywhere on them, or they have become difficult to open or close, they may need to be replaced.
