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

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

  • Protect your valuables from fading: When you switch to energy-efficient windows with low-emissivity coatings, your floors, carpets and furniture will fade less because of their ability to filter out harmful UV rays.
  • Protect your investment: When you have an older home, your windows could also be outdated or drafty. Upgrading your windows is an important part of maintaining your property and its value.
  • Reduce your carbon footprint: By using less energy once upgrading to Energy Star certified windows, you’ll also be cutting your indirect greenhouse gas emissions by about 12%, according to Energy Star.
  • Save on power bills: According to the Department of Energy, heat gained or lost through windows makes up about 25-30% of household energy use. Switching to energy-efficient models can help reduce how much you have to pay, therefore saving you about 12% more on your bills.

Estimated Cost of Window Replacement in East Northport

Windows come in all shapes and sizes, so costs and services will differ greatly. Here are the average costs and services that you can find from window installation companies.

How Much Do New Windows Cost?

Although the national average cost to install a single window is around $600, it can range from $200 to $1,200. Costs will vary significantly based on the current condition of your home, the number of windows you need, the quality of your products and your location. Many window companies also offer door installations and other add-ons like shutters, coating, baths and more. Additional services will increase overall project costs.

Whether or not you opt for energy-efficient windows is another factor that will determine the cost. These will usually cost more than other windows, but on the other hand, you can save about $215 a year on your energy bills in East Northport.

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

What Services do Window Installers Offer?

In regard to window replacements, there are generally two kinds that your installer will offer: full-frame and pocket installations.

Full-frame installations entail replacing the total window, including the sill, frame and trim. You most likely need a full-frame installation when you want a new style or your window has considerable rot or deterioration. Because these installations are more involved, they will increase overall costs. A pocket installation means replacing a window within the existing frame, which tends to be less expensive than a full-frame installation.

If you’re still trying to decide which kind of installation you need, you can consult with your installer and get their advice. The decision mostly is influenced by how old the frames are and if there’s any damage.

How We Choose the Best Window Installers in East Northport

The EcoWatch Reviews team is different from most reviewers, as we evaluate these companies through a sustainability lens. Along with energy efficiency, we analyzed several window installers in East Northport and ranked them using the following methodology:

Service Area

Because this is a guide for East Northport, we only included companies that serve the city. There are certainly reputable providers that didn’t make the list because they wouldn’t be able to serve homeowners in East Northport.

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 type of window you get. We do rate window installers higher if they offer high-quality products, but we also factor in workmanship as reflected in customer feedback.

Customer Reviews

We analyzed patterns in recent online reviews to determine the companies with the highest rates of customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across nearly every category, including quality of installation, warranty, professionalism, quality of parts, cost and more.

Cost

This one is a give-and-take: similar to most services, cheap window installation companies may not provide the highest quality service. On the other hand, we want to ensure we’re highlighting companies that provide a spectrum of price and financing options so they’re accessible to most homeowners.

Warranty

Protecting your investment in new windows is important. For that reason, window installation companies that give you lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Last but not least, we like to see companies that have a good track record in the industry. Window installers that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.

East Northport, NY Window Replacement FAQs

What is the average cost to install new windows in a home?

The national average cost of installing a single window is around $600 but can range from $200 to $1,200, depending on a variety of factors. The price is typically dependent on the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more initially but can save you hundreds of dollars a year in energy bills.

What kind of window is the most energy-efficient?

Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. To be sure you’ll get the most energy-efficient windows, look for models with the blue Energy Star certification — they’re certified energy-efficient by the U.S. Department of Energy.

What services do window installation companies do?

Window installers go to your house to remove your old windows and replace them with new ones. Some companies install products sold by other companies, whereas others install their own windows. The installer will also clean up after the installation is finished.

How often should you replace your windows?

Windows have a typical lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Other than that, if your windows have any damage on them, or they have become difficult to open or close, they may be in need of replacement.
