How Installing Energy-Efficient Windows in Ronkonkoma Saves You Money

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

  • Reduce your carbon footprint: Decreasing how much energy you use also lowers your carbon emissions. You could reduce it by 307 pounds per year on average.
  • Save money on electricity bills: Switching to energy-efficient windows reduces your energy bills by about 12% because you use less energy.
  • Protect your investment: The older your home is, the more likely it is that switching to energy-efficient windows will benefit you. Older homes tend to have windows that are outdated, drafty or potentially even damaged in some way. Updating your windows could help raise the value of your property if you decide to sell.
  • Protect your valuables from fading: The low-emissivity coatings on some energy-efficient windows filter out harmful UV rays, preventing fading of your furniture, carpet and other valuables.

Estimated Cost of Window Replacement in Ronkonkoma

Windows come in various shapes and sizes, so costs and services will differ considerably. Here are the average costs and services that you’ll find from the average window installation company.

How Much Do New Windows Cost?

According to our research, the national average cost of replacing a single window is around $600. However, window replacement costs can range from $200 to $1,200 for each window. But costs will vary considerably depending on the current condition of your home, your location, the quality of your products and the number of windows you need. A lot of window companies also offer door installations and other add-ons like baths, shutters, coating and more. These extra services will increase overall project costs.

With windows, efficiency is one of the most important factors for most homeowners. Windows with higher efficiency may cost more initially, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide decades of energy savings. According to Energy Star, buying certified energy-efficient windows can save Ronkonkoma homeowners $215+ a year after replacing single-pane windows.

The cost of your window installation will also vary based on the kind of window material you choose for the frames. Wood windows are usually the most expensive, although it depends on whether they are 100% wood or clad with aluminum or vinyl. Fiberglass windows also tend to be somewhat more expensive than vinyl, but they are shown to be more efficient.

What Services do Window Installers Offer?

The first step when considering a window installation is to decide whether you want a full-frame or pocket installation.

A full-frame installation is a total window replacement. It involves taking out the old window, the sill, and the exterior and interior trim. It can also involve extra materials, such as insulation and drip edges, which increase the overall cost of the project. Also worth noting: you may have to touch up the paint around the window after a full-frame installation. 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 not sure which type of window installation service you need, your installer can help you out. In general, the decision depends on factors like the age and condition of the home, the type of building material, budget and time restrictions.

How We Choose the Best Window Installers in Ronkonkoma

In our hunt to make your home improvements easier and more eco-friendly in Ronkonkoma, the EcoWatch Reviews team evaluated dozens of companies before settling 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 pretty self-explanatory, but we’ve chosen to highlight window installation companies that serve Ronkonkoma so you can find a quality window installation company near you.

Work Quality

When installing new windows, the quality and variety of services often plays just as important of a role in insulation and performance as the brand you opt for. 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

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

Cost

Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs as low as 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. That’s why window installation companies that offer lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Lastly, we like to see companies that have a proven track record in the industry. Window installation companies that have more experience will earn higher rankings by our standards. We like to see at least ten years of experience.

Ronkonkoma, NY Window Replacement FAQs

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

The average cost of replacing a window can range from $450 to $650. There are many factors that affect the price, which include styles and sizes of windows, the materials used in designing the windows, the number of windows, your property’s location, how energy-efficient the windows are and local labor costs.

What are the most common types of replacement windows?

There are various kinds of windows you can get for your home, such as picture windows, bay windows, double-hung and single-hung windows, slider windows, casement windows, transom windows and awning windows.

Can you install your own windows?

If you’re handy and know how to replace a window, you may be able to install your own windows. However, if you don’t have the time or skills, we recommend hiring a professional.

How often do you need to replace windows?

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

Should I replace all my windows at the same time?

If you’re upgrading your windows because of energy-efficiency, replacing all the windows at the same time is the only way to gain that benefit. On the other hand, if you have just a few windows that are damaged or leaky, you can replace just those.
