How Installing Energy-Efficient Windows in Islip Saves You Money

There are several benefits of switching to energy-efficient windows. Some reasons you may want to consider making the change include the following:

• Reduce your carbon footprint: In Islip, you can lower your indirect greenhouse gas emissions by about 307 pounds per year after you switch to energy-efficient windows.
• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.
• Save money on electricity bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of residential energy use. Installing energy-efficient models can help lower that number, therefore saving you about 12% more on your bills.
• Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or potentially even damaged in some way.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 Islip

Let’s take a look at the cost of replacing your windows and the kinds of services you may need for your home.

How Much Do New Windows Cost?

On average, Islip homeowners can anticipate their window installations to range from $250 to $1,200. The average cost is at around $600. These estimates vary based on specific characteristics of your installation, such as material, type, the location of your home, number of windows, size and more.

Keep in mind that energy-efficient windows may cost more upfront, but Energy Star estimates the upgrade will save you between $101 and $583 a year when replacing single-pane windows and between $27 and $197 per year when you install double-pane, clear glass windows. Your exact savings will vary depending on your local climate, energy rates and individual home characteristics.

Asking for free quotes from several companies is the best way to find out which one will work best for your budget.

What Services do Window Installers Offer?

When considering window replacements, there are typically two types that your provider will offer: full-frame and pocket installations.

Full-frame installations are necessary when you want a new style or your window has a lot of rot. With this service, your installers will replace the total window, including the trim, sill and frame. Pocket installations (or retrofits) involve installing a new window within the existing frame, which makes pocket installations take less time and therefore cost less. But, if the frame has any damage or rot, you should opt for a full-frame installation instead.

If you’re not sure which window installation service you need, your installer can advise you. Typically, the decision is based on factors like the age and condition of the home, the type of building material, budget and time restrictions.

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.
