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

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

  • Protect your valuables: Many energy-efficient 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.
  • Decrease your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you'll also be cutting your carbon dioxide emissions by about 12%, according to Energy Star.
  • Protect your investment: Keeping your windows up to date is an important part of maintaining your property and its value, particularly if you have an older home.
  • Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of residential energy use. Upgrading to energy-efficient models can help lower how much energy is used in your home, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in Islip Terrace

Each window installation company offers varying services and has different prices based on a few factors.

How Much Do New Windows Cost?

Typically, Islip Terrace homeowners can expect their replacement window installations to range from $250 to $1,200. The most common installations sit at about $600. 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 companies also provide door installations, which will add extra costs to your project.

With windows, efficiency is the most important factor for most homeowners. High efficiency windows may cost more off the bat, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Islip Terrace homeowners $215+ each year after replacing single-pane windows.

Getting free quotes from several providers is the best way to figure out which one is right for you.

What Services do Window Installers Offer?

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

A full-frame installation is a total window replacement. This service involves removing the old window, the sill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which raise the total cost of the project. It's also worth noting that you may have to touch up the paint surrounding the window after a full-frame installation. A pocket installation entails installing a new window without replacing the frame. So, instead of removing the whole unit and rebuilding it, the contractor will just slide the replacement window (also called a retrofit or insert window) into the frame.

If you're unsure which window installation service you need, your installer can advise you. Typically, the decision is influenced by factors such as the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Islip Terrace

In our search to make your home improvements easier and more eco-friendly in Islip Terrace, the EcoWatch Reviews team chose the above companies as the top window installation companies in the city. Along with energy efficiency, we analyzed several window installers in Islip Terrace and ranked them using the following methodology:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve Islip Terrace so you can find the best window installation company near you.

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 get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another very important review factor. If the majority of customers don't have good things to say about their experience with a certain window installation company, 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 low when possible. When analyzing the prices of providers, we awarded 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 that offer 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 a proven track record in the industry. Window installers that have more years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Islip Terrace, NY Window Replacement FAQs

How much does a window install cost?

The national average cost to replace a window is around $600 but can range from $200 to $1,200, based on several factors. The price is usually influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

What are the different types of windows?

The most common types of windows for homes include: bay windows, slider windows, double-hung and single-hung windows, casement windows, picture windows, transom windows and awning windows.

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 involved process that can be difficult to do on your own, so it's best left to the professionals.

How long does window installation typically take?

Each window takes about 30 minutes to install based on the type of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that must be installed.

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

Windows generally have a lifespan of around 20 to 30 years, but anytime you see damage on your windows, it's a good idea to have them checked by an expert to see if they need any repairs or replacements.
