How Installing Energy-Efficient Windows in East Shoreham Saves You Money
By upgrading to energy-efficient windows, you and your family can take advantage of several benefits, such as:
- More efficient energy use in your home: Because the summers can get quite hot in East Shoreham, homeowners often rely on their air conditioner a lot. Energy-efficient windows decrease how much cool air is lost through your windows, making it easier to keep your house cool.
- Reduce your carbon footprint: Reducing how much energy you use also lowers your indirect greenhouse gas emissions. You could reduce it by about 307 pounds.
- 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.
- More efficient energy usage in your household: In East Shoreham where the winters can get very cold, energy-efficient windows reduce how much heat is lost through your windows, making it easier to keep your home warm.
Estimated Cost of Window Replacement in East Shoreham
Windows come in different shapes and sizes, so costs and services will vary greatly. Here are the typical costs and the primary services that you can find from window installers.
How Much Do New Windows Cost?
Generally, East Shoreham homeowners can anticipate their window replacements to range from $250 to $1,200. The average cost is at around $600. These estimates are based on the specifics of your installation, including size, type, material, number of windows, the location of your home and more.
It's also worth keeping in mind that energy-efficient windows will typically cost more initially, but Energy Star predicts that switching out the windows on your East Shoreham 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. The amount of money you'll save by installing energy-efficient windows depends on your local climate, energy rates and other factors unique to your home.
We advise getting free quotes from several window companies to find the right windows and the company that works best for your budget.
What Services do Window Installers Offer?
The first step of a window replacement is to clarify whether you need a full-frame or pocket installation.
Full-frame installations are usually recommended when you want to change the style of your windows or your window has significant rot or deterioration. With this service, your installers will replace the full window, including the sill, frame and trim. Pocket installations are on the simpler end and won't cost as much, as they entail simply replacing the window within its existing frame. But if the frame has any damage, you may need a full-frame installation instead.
If you're not sure which kind of window installation service you should get, your installer can assist you. 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 East Shoreham
The EcoWatch Reviews team is different from most reviewers, as we assess these companies through a sustainability lens. Along with energy efficiency, we analyzed each installer and assigned rankings based on the following methodology:
Service Area
This one is self-explanatory, but we've chosen to highlight window installation companies that serve a wide variety of states and cities so you can find the best window installation company near you.
Work Quality
When choosing new windows, the quality and breadth of services often plays just as important of a role in overall efficiency and performance as the brand of window you opt for. We do give window installers more points if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.
Customer Reviews
We analyzed trends in recent online reviews to find the companies with the most 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, warranty, quality of installation, quality of parts, cost and more.
Cost
This one is a give-and-take: as with most services, cheap window installers won't always provide the most quality service. On the other hand, we want to make sure we're highlighting companies that provide a spectrum of price and financing options so they're accessible to most homeowners.
Warranty
As discussed previously, windows are a substantial investment, so you'll want to be certain that investment is well protected. Window installation companies that have 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 years of experience will earn higher rankings by our standards. We like to see at least ten years of experience.
East Shoreham, NY Window Replacement FAQs
How much does a window install cost?
The national average cost to replace one window is about $600 but can range from $200 to $1,200, based on a few different factors. The price is typically influenced by the type and material of the window, the size of the window and the location of your property. Also, remember that energy-efficient windows may cost more upfront but can save you hundreds of dollars a year in energy bills.
What are the most common kinds of replacement windows?
The most common types of windows for homes include: transom windows, double-hung and single-hung windows, casement windows, bay windows, picture windows, awning windows and slider windows.
Can you install your own windows?
If you're handy and have the time and patience to do the job right, it's possible to install your own windows. But if you don't have the time or skills, we recommend hiring a professional.
How often should you replace windows?
Windows have an average lifespan of about 20 to 30 years. If your windows are older than that, they should probably be replaced. Apart from that, if your windows have any damage on them, or they have become difficult to open or close, they may need to be replaced.
Should I replace my windows all at once?
If you want to get more efficient windows and save money on energy costs, replacing all of your windows together is the only way to gain that benefit. However, if you have only a few windows that are broken or drafty, you can replace just those.
