How Installing Energy-Efficient Windows in Islip Saves You Money

By switching to energy-efficient windows, you can take advantage of several benefits, including:

• Decrease your carbon footprint: In Islip, you can cut your indirect greenhouse gas emissions by about 307 pounds per year after you upgrade to energy-efficient windows.
• Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will be protected from fading because of their ability to filter out harmful UV rays.
• Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for about 25-30% of household energy use. Installing energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.
• Protect your investment: Upgrading and repairing your windows is an important part of maintaining your property and its value, especially if your home is on the older side.

Estimated Cost of Window Replacement in Islip

Windows come in various shapes and sizes, so costs and services will vary remarkably. Here are the typical costs and services that you'll find from window installation companies.

How Much Do New Windows Cost?

According to our research, the typical cost to replace a single window is about $600. However, window replacement costs can range from $200 to $1,200 a window. These numbers vary based on specific characteristics of your installation, like material, number of windows, the location of your home, size, type and more.

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

We recommend getting free quotes from several window installers to find the one that works best for your budget.

What Services do Window Installers Offer?

In general, there are two kinds of window installation services companies offer: full-frame and pocket installations.

Full-frame installations involve replacing the full window, including the frame, trim and sill. You most likely need a full-frame installation when you want to change the style of your windows or your window has noticeable damage. Full-frame installations are more involved and will increase the overall cost. Pocket installations (or retrofits) entail replacing a window within the existing frame, which makes pocket installations more simple and affordable. But, if the frame has any rot or deterioration, you will likely need a full-frame installation instead.

Your window installation company should be able to help you figure out which type of installation you need.

How We Choose the Best Window Installers in Islip

EcoWatch is different from most reviewers because we assess these companies through a sustainability lens. We have reviewed the top window replacement companies in Islip mainly 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 cut your electricity bills by hundreds of dollars. Along with energy efficiency, our rating methodology considers the following factors:

Service Area

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

Work Quality

We're willing to bet that you're looking for a company to do a great job installing windows. We've vetted each installer featured in our guide to make sure its contractors are well-qualified and that the company has gotten 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 highest rates of customer satisfaction. Customer satisfaction might be the most important factor, as it reflects the quality of services across most other categories, including professionalism, quality of installation, quality of parts, warranty, cost and more.

Cost

Cheaper windows don't necessarily mean better windows, but we know many of our readers would like to keep costs as low as 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. That's why window installation companies that give you lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Due to Islip's climate, homeowners need to be wary of rot, low efficiency and water damage. We factored in local experience to reflect the ability of 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.
