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

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

• Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only insulate your home better, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
• Save money on power bills: According to the Department of Energy, heat gained or lost through windows accounts for around 25-30% of household energy use. Switching to energy-efficient models can help lower that amount, therefore saving you about 12% more on your bills.
• Protect your investment: When your home is on the older side, your windows could also be outdated or damaged. Upgrading and repairing your windows is an important part of maintaining your property and its real estate value.
• Decrease your carbon footprint: In East Islip, you can cut your indirect greenhouse gas emissions by about 307 pounds per year once you install energy-efficient windows.

Estimated Cost of Window Replacement in East Islip

Let's take a look at the cost of window installation and the types of services you may need for your home.

How Much Do New Windows Cost?

On average, East Islip homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost sits at approximately $600. But costs will differ considerably depending on the quality of your products, the current condition of your home, the number of windows you need and your location. A lot of window companies also offer door installations and other add-ons like coating, baths, shutters and more. Additional services will increase your overall project costs.

It's also worth keeping in mind that energy-efficient windows will almost always cost more initially, but Energy Star estimates that upgrading the windows on your East Islip home can mean an average energy savings of $236 to $319 each year for single-pane window replacement, or between $87 to $126 each year for double-pane windows. How much you'll save by upgrading to energy-efficient windows varies based on your local climate, energy rates and other factors unique to your home.

Costs will also vary depending on the material you pick for your window frames. Aluminum frames have the lowest price. They're sturdy, light and easy to maintain, but provide poor insulation. Vinyl frames are somewhat expensive and provide good insulation. Composite frames made from wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames cost the most and are the most in-demand. They're also aesthetically pleasing and provide decent insulation for your home.

What Services do Window Installers Offer?

In regard to window installations, there are typically two types that your provider will offer: full-frame and pocket installations.

A full-frame installation is a replacement of the full window. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve extra materials, including insulation and drip edges, which raise the overall cost of the project. It's also worth noting that it's not uncommon for homeowners to have to touch up the paint surrounding the window after a full-frame installation. A pocket installation involves replacing a window within the existing frame, which tends to be cheaper than a full-frame installation.

If you're hiring a reputable window installation company, your company will be able to advise you on the best type for your project. In East Islip, the choice will mostly depend on the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in East Islip

In our hunt to find the most reliable, eco-friendly window installers in East Islip, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. Along with energy efficiency, we evaluated window companies all across the state and assigned rankings using the following methodology:

Service Area

Because this is a guide for East Islip, we paid more attention to companies that provide services to the city. There are other reputable providers that didn't make the list because they wouldn't be able to serve homeowners in East Islip.

Work Quality

When choosing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the brand you choose. We do rate window installers higher 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 determine the companies with the most customer satisfaction. Customer satisfaction may be the factor we place the most value on, as it indicates the quality of services across most other categories, including professionalism, quality of parts, warranty, cost, quality of installation and more.

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

As discussed previously, windows are a sizable investment, so you'll want to be certain that investment is protected. Window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.

Years of Experience

Because of East Islip's climate, homeowners will want to mitigate rot, water damage and low efficiency. We factored in local experience to reflect the ability of East 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.
