How Installing Energy-Efficient Windows in Port Jefferson Saves You Money

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

  • Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which filter out damaging UV rays, reducing fading of your furniture, carpet and other valuables.
  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes usually have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help increase the value of your home if you decide to sell.
  • Reduce your carbon footprint: You can reduce your indirect greenhouse gas emissions by about 12% after you install Energy Star certified windows. In Port Jefferson, that's about 307 pounds per year on average.
  • Save money on power bills: Since energy-efficient windows decrease the amount of energy used to heat or cool your home, the switch can help you save about $437 annually on your energy bills in Port Jefferson.

Estimated Cost of Window Replacement in Port Jefferson

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

How Much Do New Windows Cost?

Typically, Port Jefferson homeowners can anticipate their window replacements to range from $250 to $1,200. The most common installations sit at approximately $600. These estimates are based on specific characteristics of your installation, such as number of windows, the location of your home, type, size, material and more.

Whether or not you pick energy-efficient windows is another factor that will influence the cost. These will almost always cost more than other windows, but on the other hand, you can save about $437 a year on your energy bills in Port Jefferson.

Something else that influences the overall cost is the material you select for your frame. Aluminum frames are generally the least pricey and are sturdy and light, but they offer poor insulation. On the other hand, wood frames are the most expensive, as they are aesthetically pleasing and offer decent insulation. Fiberglass and vinyl frames provide good insulation and cost somewhere between the other two.

What Services do Window Installers Offer?

In regard to window replacements, in general there are two types that your provider will have: full-frame and pocket installations.

Full-frame installations require replacing the full window — the sill, frame, trim and all. These are most common when you want a new style for your windows or when it has a great amount of rot or deterioration. Full-frame installations involve more time and labor and will increase overall costs. Pocket installations are on the simpler end and won't cost as much, as they entail merely replacing the window within its existing frame. But if the frame has any damage or deterioration, you may have to get a full-frame installation instead.

Your window installation company should be able to help you decide what's best for your needs. In Port Jefferson, the decision will mostly depend on the age of your windows and if there's any damage. Wood can decay if not properly maintained over the years, so it's a good idea to have a professional evaluate your frames and window sills.

How We Choose the Best Window Installers in Port Jefferson

EcoWatch reviews are different from most reviews because we look at these companies through a sustainability lens. Along with energy efficiency, we evaluated several window installers in Port Jefferson and assigned rankings using the following methodology:

Service Area

Since this is a guide for Port Jefferson, we gave more points to companies that cover the city. There are other reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Port Jefferson.

Work Quality

We're willing to bet that you're looking for professionals who do a great job installing windows. We've vetted each company on this list to make sure its technicians are well-qualified and that the company has gotten lots of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed patterns in recent online reviews to find the companies with the highest rates of customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across nearly every category, including professionalism, quality of installation, quality of parts, cost, warranty 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 providers' prices, we awarded higher points to companies with reasonable prices and accessible financing rather than "cheaper" services.

Warranty

As discussed, windows are a serious investment, so you'll want to be certain that investment is well protected. Window installation companies that provide 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 been in the industry for a while. Window installation companies that have more years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

Port Jefferson, NY Window Replacement FAQs

What is the average cost to replace windows in a home?

The average cost of installing one window can range between $450 and $650. There are a variety of factors that affect how much it costs, which include styles and sizes of windows, your property's location, local labor costs, the materials used in designing the windows, the number of windows and how energy-efficient the windows are.

Which type of window is the best?

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

Can you replace your own windows?

If you're handy and have experience with installing a replacement window, you may be able to install your own windows. However, if you don't have the time or know-how, we recommend getting a professional to do it for you.

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

Replacement windows can be installed during any season, but autumn might be best. Regardless of when you install them, the contractors will take steps to ensure that too much hot or cold air doesn't get into your home, so the temperature outside doesn't necessarily matter that much. Most importantly, the weather should be dry.

Should I replace my windows all at the same time?

If you want to get more efficient windows and save money on energy costs, replacing all of your windows at once is the only way to gain that benefit. On the other hand, if you have only one or two windows that are broken or leaky, you can replace just those.
