How Installing Energy-Efficient Windows in Smithtown Saves You Money

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

  • Save on energy bills: Upgrading to energy-efficient windows lowers your energy bills by about 12% since you use less energy.
  • Protect your valuables from fading: When you switch to energy-efficient windows that have low-emissivity coatings, your floors, carpets and furniture will be protected from fading due to their ability to filter out damaging UV rays.
  • Decrease your carbon footprint: By using less energy once upgrading to energy-efficient windows, you’ll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Upgrading your windows can make your home more comfortable and also help increase the value of your house if you decide to sell.

Estimated Cost of Window Replacement in Smithtown

Windows come in various shapes and sizes, so costs and services will vary tremendously. Here are the typical costs and services that you can find from window installation companies.

How Much Do New Windows Cost?

The average cost to install a single window is about $600 but can range from $200 to $1,200. But prices vary remarkably depending on the size of your home, complexity of the installation, your location and the quality of the company you choose. Many window installers also provide door replacements, which will make your project cost more.

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

Getting free quotes from multiple companies is the best way to find out which one is right for you.

What Services do Window Installers Offer?

There are generally two kinds of window installation services: full-frame and pocket installations.

A full-frame installation replaces the total window, such as the windowsill, frame, trim and the window panes. Because this kind of installation requires more time and labor, it will cost more than a pocket installation. A pocket installation entails replacing a window within the existing frame, which is generally cheaper than a full-frame installation.

If you’re still debating which type of installation you need, you can ask your installer and get their advice. The choice mostly depends on how old the frames are and if there’s any damage present.

How We Choose the Best Window Installers in Smithtown

In our search to find the most reliable, eco-friendly window installers in Smithtown, the EcoWatch team examined many companies before deciding on these. Along with energy efficiency, we evaluated several window installers in Smithtown and assigned rankings using the following methodology:

Service Area

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

Work Quality

We’re willing to bet that you’re looking for a company to do a great job installing windows. We’ve vetted each installer featured on this list to ensure its technicians are well-qualified and that the company has received plenty of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent online reviews to determine the companies with the most customer satisfaction. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including warranty, cost, quality of parts, quality of installation, professionalism 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 previously, 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 labor 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 are going to earn higher rankings by our standards. We like to see at least ten years of experience.

Smithtown, NY Window Replacement FAQs

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

The national average cost of replacing one window is around $600 but can range from $200 to $1,200, depending on a few different factors. The price is generally dependent on the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more upfront but can save you a decent amount of money a year in energy bills.

Which kind of window should I get?

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

Can I replace my own windows?

Although it is possible to install your own windows, doing so requires a lot of time and experience with home improvement projects. Hiring a professional can help ensure that the job is done properly and that you can avoid spending the time and effort of doing it yourself.

When is the best time of year to replace windows?

Though you can install windows any time of year, warmer weather is typically better for replacing windows. Additionally, the weather should be dry, as rain can make the installation harder.
