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

Energy-efficient windows can benefit you in several ways. Here are some reasons you may want to make the switch:

  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent the fading of your floors, carpets and furniture by filtering out UV rays.
  • Save on power bills: Once you install energy-efficient windows, you can see a reduction in your bills by about 12% since you’ll need less energy to heat or cool your house.
  • Decrease your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by about 307 pounds.
  • Protect your investment: When your home is on the older side, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its value.

Estimated Cost of Window Replacement in Central Islip

Each window installer offers varying services and has different price points depending on a few factors.

How Much Do New Windows Cost?

Although the national average cost of installing a single window is around $600, it can range from $200 to $1,200. These figures are based on the specifics of your installation, like the location of your home, type, material, number of windows, size and more.

It’s also worth keeping in mind that energy-efficient windows will usually cost more upfront, but Energy Star predicts that upgrading the windows on your Central Islip home translates to an average energy savings of $236 to $319 a year for single-pane window replacement, or between $87 to $126 per year for double-pane windows. How much you’ll save by upgrading to energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.

Costs will also vary depending on the material you choose for your window frames. Aluminum frames have the lowest price. 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 with wood fibers encased in plastic also provide good insulation and are moderately expensive. Wood frames are the most expensive and are the most in-demand. They’re also aesthetically pleasing and offer decent insulation for your home.

What Services do Window Installers Offer?

The first step of a replacement is to decide whether you need a full-frame or pocket installation.

A full-frame installation is a total window replacement. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve extra materials, like insulation and drip edges, which increase the overall cost of the project. It’s also worth noting that you may have to touch up the paint around the window after a full-frame installation. A pocket installation entails replacing a window without replacing the frame. This means instead of taking out the whole window and reinstalling it, the contractor will just put the replacement window (also called a retrofit or insert window) into the frame.

Your window replacement company will be able to help you choose what’s best for your needs. In Central Islip, the decision will mostly be based on how old your home is and if there’s any damage. Wood can decay if not maintained properly over the years, so it’s a good idea to have a professional check on your frames and window sills.

How We Choose the Best Window Installers in Central Islip

In our search to find the most reliable, eco-friendly window installers in Central Islip, the EcoWatch Reviews team assessed many companies before landing on these. Along with energy efficiency, we analyzed window companies all across the state and ranked them based on the following methodology:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve Central Islip so you can find a quality window installation company near you.

Work Quality

When it comes to new windows, the quality and variety of services can often play just as important of a role in overall efficiency and performance as the brand of window you opt for. We do give window installers higher marks if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

Customer feedback is another super important review factor. If most customers don’t have good feedback about their service from a certain window installation company, you won’t see it featured on EcoWatch.

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers want 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

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that offer lengthy warranties for products, parts and labor 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 installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

Central Islip, NY Window Replacement FAQs

How much does a window install cost?

The average cost to replace a window ranges from $450 to $650. There are several factors that influence the price, such as local labor costs, your property’s location, how energy-efficient the windows are, the materials used in designing the windows, styles and sizes of windows and the number of windows.

Which type of window is the best?

A window’s energy efficiency is affected by a number of factors, such as the quality of the installation and what kind of window it is. Look for Energy Star Certified windows — these are often the most energy-efficient and are certified by the U.S. Department of Energy.

What do window installation companies do?

Window installation professionals cover the entire process — from replacing old windows with brand-new ones to cleaning up after the windows have been put in place. In addition, some companies offer window manufacturing, customization and repairs.

What time of year is the best time to replace my windows?

Although you can install windows any time of year, warmer weather is often better for installing replacement windows. In addition, it shouldn’t be raining, since rain can make the installation harder.
