How Installing Energy-Efficient Windows in Stony Brook Saves You Money

There are quite a few perks of switching to energy-efficient windows. A few reasons you may want to consider making the change include the following:

  • Protect your investment: If your home is on the older side, your windows are most likely outdated. Updating your windows can improve the insulation in your home and also help increase the value of your property if you decide to sell.
  • Protect your valuables: The low-emissivity coatings on many energy-efficient windows help prevent your floors, carpets and furniture from fading by filtering out UV rays.
  • Save money on electricity bills: Since energy-efficient windows lower how much energy you need to heat or cool your home, the switch can help you save about $215 annually on your energy bills in Stony Brook.
  • Better temperature control in your home: When you reside in a place like Stony Brook where the summers can get quite hot, you often have to depend on your air conditioner to keep your house cool. Energy-efficient windows can reduce how much cool air is lost through your windows when cooling your home.

Estimated Cost of Window Replacement in Stony Brook

Let's take a look at the cost of installing new windows and the types of services offered by installers.

How Much Do New Windows Cost?

Generally, homeowners in Stony Brook can expect that most replacement window installations will cost between $250 and $1,200, with the most common installations sitting at around $600. How much it will cost depends on several factors, like type, material, the location of your home, size, number of windows and more.

With windows, efficiency is the most important factor for many homeowners. High efficiency windows may cost more upfront, 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 Stony Brook homeowners $215+ each year after replacing single-pane windows.

We recommend requesting free quotes from several window installation companies to find the one that works best for your budget.

What Services do Window Installers Offer?

The first question to ask yourself when getting new windows is: Should you get a full-frame installation or a pocket installation?

A full-frame installation is a replacement of the total window. It involves removing the old window, the sill, and the exterior and interior trim. It can also involve additional materials, such as insulation and drip edges, which increase the overall cost of the project. Also worth noting: it's not uncommon for homeowners to have to touch up the paint around the window after a full-frame installation. Pocket installations are on the simpler end and won't carry as large a bill, as they entail merely 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 replacement company should be able to help you choose what's best for your needs. In Stony Brook, the decision will mostly be based on the age of your windows and if there's any damage. Wood can decay if it's not maintained properly over the years, so it's good to have a professional check your frames and window sills.

How We Choose the Best Window Installers in Stony Brook

EcoWatch differs from other reviewers since we look at these companies through a sustainability lens. We've assessed the best window installers in Stony Brook mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can lower energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

Because this is a guide for Stony Brook, we only included companies that provide services to the city. There are certainly reputable providers that didn't make the list because of the low odds that they would serve the average homeowner in Stony Brook.

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 company in our guide 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

Customer feedback is another super important review factor. If most customers don't have positive feedback about their service from a certain company, it won't be featured on EcoWatch.

Cost

This one is a give-and-take: as with most services, cheap window installers are not going to provide the most quality service. Still, we want to ensure we're highlighting companies that provide a variety of price and financing options so they're accessible to most homeowners.

Warranty

Protecting your investment in new windows is important to many homeowners. That's why window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Stony Brook's climate, homeowners need to be wary of water damage, rot and low efficiency. We factored in local experience to reflect the ability of Stony Brook window companies to prepare homes for these issues. If a company has less than 10 years of experience, it loses points in this category.

Stony Brook, NY Window Replacement FAQs

What is the typical cost to replace windows?

The national average cost of installing one window is about $600 but can range between $200 and $1,200, based on a few different factors. The price is often influenced by the size of the window, the type and material of the window and the location of your property. Also, keep in mind that energy-efficient windows may cost more upfront but can save you hundreds of dollars 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. To be sure you'll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — that means they're certified energy-efficient by the U.S. Department of Energy.

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. But if you don't have the time or skills, we recommend getting a professional to do it for you.

When is it time to replace your windows?

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