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

Upgrading to energy-efficient windows can help improve the comfort of your home and help you save on power bills. Here are more details about how switching out your windows could benefit you:

  • Save money on energy bills: Because energy-efficient windows reduce how much energy you need to heat or cool your home, they can help you save around $215 annually on your energy bills in West Islip.
  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
  • Reduce your carbon footprint: In West Islip, you can lower your indirect greenhouse gas emissions by about 307 pounds per year once you switch to energy-efficient windows.
  • 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 Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way.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.

Estimated Cost of Window Replacement in West Islip

Windows come in various shapes, purposes and styles, so costs and services will vary greatly based on several factors. Below, we describe the typical cost and services that you can get from window installers.

How Much Do New Windows Cost?

Though the typical of installing one window is about $600, it can range anywhere from $200 to $1,200. Costs will vary considerably based on your location, the quality of your products, the number of windows you need and the current condition of your home. Many window companies also offer door installations and other add-ons like shutters, baths, coating and more. These extra services will increase overall project costs.

With windows, efficiency is the most important factor for most homeowners. Windows with higher efficiency may cost more off the bat, but by increasing the efficiency of your home — especially during the summer and winter — they can provide decades of energy savings. According to Energy Star, purchasing certified energy-efficient windows can save West Islip homeowners $215+ a year after 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 maintenance-free, but offer poor insulation. Vinyl frames are a bit more expensive and offer good insulation. Composite frames made using 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 require replacing the entire window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant damage. Full-frame installations are more involved and will increase overall costs. Pocket installations (also known as retrofits) are when you replace a window without replacing the frame. Pocket installations are on the simpler end and won't cost as much, but you can't do this type of installment if you have any pre-existing rot or water damage.

Your window installation company can recommend the best type for your project. In West Islip, the decision will mostly depend on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in West Islip

In our search to make your home improvements easier and more eco-friendly in West Islip, the EcoWatch Reviews team examined dozens of companies before settling on these. We've assessed the top window installers in West Islip mostly based on their energy efficient offerings, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can reduce your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

This one is self-explanatory, but we've chosen to highlight window installers that serve a wide variety of states and cities so you can find the best 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 choose. We do give window installers more points 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 most important factor, as it reflects the quality of services across most other categories, including cost, professionalism, quality of parts, quality of installation, warranty and more.

Cost

This one is a give-and-take: similar to other services, cheap window installation companies may not provide the highest quality service. Still, we want to make sure we're highlighting companies that offer a wide range of price and financing options so they're accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. That's why window installation companies that provide 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 experience will earn higher rankings by our standards. We like to see at least ten years of experience.

West Islip, NY Window Replacement FAQs

What is the average cost to install windows in a home?

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

Which type of window should I get?

A window's energy efficiency is affected by 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 installation professionals will do the entire process — from replacing old windows with new ones to cleaning up afterward. In addition, some companies offer window manufacturing, customization and repairs.

How long does it usually take to install windows?

Because the average installation time of a window is 30 minutes, around 16 windows can be installed in an 8-hour work day.

Should I replace my windows all at once?

If your windows are more than 20 years old, you probably need to replace all of them. By that point, they are often less efficient, leakier and/or more damaged than new windows. Replacing your windows all at once will involve less paperwork and less stress.
