Why you can trust EcoWatch

Our panel of energy experts work tirelessly to create unbiased reviews and informative content to help homeowners make educated decisions. No other windows site has covered energy efficiency and sustainability as long as EcoWatch, which means we're going to help you find windows replacements that will save on your energy bill and put more money back in your wallet.

Although eco-friendly energy sources like wind and solar are important when it comes to reducing your carbon footprint, improving your house's energy efficiency can also have a big impact on home energy conservation. If your house has old or damaged windows, your HVAC system could be working extra hard to heat or cool your house. This means higher electricity bills.

That's bad news for both your bank account and the environment, but one of the top window installation companies can help with that.

Because windows have such a big impact on your home, selecting the right company for you is a big decision to make. That's why the EcoWatch team has made this list of the best window installation companies, so you can make an informed decision more easily.

How Installing Energy-Efficient Windows in Ronkonkoma Saves You Money

When you upgrade to energy-efficient windows, you may see several perks, including:

  • Decrease your carbon footprint: By using less energy after you upgrade to energy-efficient windows, you'll also be lowering your carbon dioxide emissions by about 12%, according to Energy Star.
  • Protect your valuables from fading: When you upgrade 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.
  • Save on energy bills: The Department of Energy estimates that heat gained or lost through windows accounts for about 25-30% of residential energy use. Installing energy-efficient windows can help lower that amount, which helps you save some money on your bills.
  • Protect your investment: The older your home is, the more likely you are to benefit from switching to energy-efficient windows. Older homes usually have windows that are outdated, leaky or maybe even damaged in some way. Updating your windows could help raise the value of your home if you decide to sell.

Estimated Cost of Window Replacement in Ronkonkoma

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

How Much Do New Windows Cost?

According to our market research, the average cost of replacing a single window is around $600. However, window replacement costs can range from $200 to $1,200 a window. These numbers are based on specific characteristics of your installation, such as number of windows, the location of your home, type, size, material 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 Ronkonkoma home translates to an average energy savings of $236 to $319 per 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 varies based on your local climate, energy rates and other factors unique to your home.

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

What Services do Window Installers Offer?

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

Full-frame installations involve replacing the total window, including the sill, trim and frame. Full-frame installations are necessary when you want a new style or your window has noticeable rot. Because full-frame installations are more involved, they will increase overall costs. Pocket installations are simpler and won't carry as large a bill because they entail simply replacing the window within its existing frame. But if the frame has any damage or deterioration, you may need a full-frame installation instead.

Your window installation company should be able to help you understand what's best for your needs. In Ronkonkoma, the decision will mostly be based on how old your home is and if there's any moisture damage. Wood can decay if it's 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 Ronkonkoma

In our search to find the most reliable, eco-friendly window installers in Ronkonkoma, EcoWatch assessed many companies before deciding on these. Along with energy efficiency, we assessed 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 Ronkonkoma so you can find a quality window installation company near you.

Work Quality

We're willing to bet that you're not looking for a company to do a shoddy job installing windows. We've vetted each installer included on this list to ensure its technicians are well-qualified and that the company has received a lot of positive customer feedback to vouch for its service.

Customer Reviews

We analyzed trends in recent customer feedback to determine the companies with the most consistent customer satisfaction. Customer satisfaction might be the factor we place the most value on, as it indicates the quality of services across most other categories, including professionalism, warranty, quality of installation, quality of parts, cost and more.

Cost

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

Warranty

Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that give you 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 years of experience earn higher rankings by our standards. We like to see at least ten years of experience.

Ronkonkoma, NY Window Replacement FAQs

How much does a window install cost?

The typical cost of installing a single window ranges between $450 and $650. There are a variety of factors that affect the cost, including local labor costs, your property's location, the materials used in designing the windows, styles and sizes of windows, how energy-efficient the windows are and the number of windows.

What are the kinds of windows?

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

What do window installers do?

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

How long does it take to install windows?

Since the average installation time is 30 minutes per window, about 16 windows can be installed in a typical 8-hour work day.

Should I replace all my windows at the same time?

If you're upgrading your windows to get more efficient windows, replacing all your windows together is the only way to see a noticeable difference. On the other hand, if you have just a few windows that are damaged or leaky, you can replace just those.
