How Installing Energy-Efficient Windows in Islip Saves You Money
Switching to energy-efficient windows can improve the comfort of your home and help you save on energy bills. Here are more details about how upgrading your windows could benefit you:
- Reduce your carbon footprint: In Islip, you can reduce your indirect greenhouse gas emissions by about 307 pounds per year once you upgrade to energy-efficient windows.
- Protect your valuables from fading: The low-emissivity coatings on many energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
- Save money on power bills: Upgrading to energy-efficient windows reduces your energy bills by about 12% since you use less energy.
- 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 Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way.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 raise the value of your home if you decide to sell.
Estimated Cost of Window Replacement in Islip
Windows come in varying shapes, styles and purposes, so costs and services will vary remarkably depending on several factors. Below, we describe the typical cost and services that you’ll find from window installers.
How Much Do New Windows Cost?
Although the national average cost of installing a single window is about $600, it can range anywhere from $200 to $1,200. This is due to the fact that window installations are based on a variety of factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.
Whether or not you choose energy-efficient windows is another factor that will determine the cost. These will almost always cost more than other windows, but on the other hand, you can save about $215 a year on your energy bills in Islip.
We advise getting free quotes from several window installation companies to find the one that works best for your budget.
What Services do Window Installers Offer?
When it comes to window installations, in general there are two kinds that your installer will have: full-frame and pocket installations.
Full-frame installations are usually done when you want a new style or your window has a lot of rot. With this service, your installers will replace the whole window, including the sill, frame and trim. A pocket installation involves replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.
Your window installer should be able to help you figure out which type of installation you should get.

How We Choose the Best Window Installers in Islip
In our hunt to make your home improvements easier and more eco-friendly in Islip, the EcoWatch Reviews team evaluated many companies before settling on these. Along with energy efficiency, we assessed window companies all across the state and assigned rankings using the following methodology:
Service Area
This one is pretty self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find a quality window installation company near you.
Work Quality
We’re certain that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each company in our guide to ensure its contractors are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.
Customer Reviews
We analyzed patterns in recent customer feedback to determine the companies with the most consistent customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across nearly every category, including cost, professionalism, quality of installation, warranty, quality of parts and more.
Cost
Cheaper windows don’t necessarily mean better windows, but we know many of our readers would like 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
Protecting your investment in new windows is important to many homeowners. That’s why window installation companies with lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more years of experience are going to earn higher rankings by our standards. We like to see at least ten years of experience.
