What Do Replacement Windows Cost Per Window on Long Island?
Most window replacement projects on Long Island fall within a fairly wide range. For a typical project, homeowners can expect:
- Basic window replacement: $600 – $900 per window installed
- Mid-range window replacement: $800 – $1,200 per window installed
- High-end window replacement: $1,200 – $1,500+ per window installed
Homes in areas such as Huntington, Smithtown (Suffolk County), and Massapequa (Nassau County) often fall in the mid-range price range.
- Basic projects involve standard vinyl windows going into existing openings with minimal adjustments. These are the most straightforward installs and tend to stay on the lower end.
- Mid-range projects include upgraded materials, larger sizes, or added features like improved glass or color options. Most Long Island homes fall here.
- Higher-end projects start to include premium materials like fiberglass and composite, custom sizing, or more involved installation work. Older homes, especially ones with worn frames or structural issues, can also push pricing into this range.
- Labor costs on Long Island also vary by region. Compared to national averages, pricing in both Nassau and Suffolk County tends to run higher due to regional demand, varying permitting requirements by town, and the age of homes in different parts of the island.
Window Prices by Material (What You’ll Actually Pay)
The material you choose has one of the biggest impacts on your total window replacement cost. It affects not just the price, but also how the window performs over time and how much upkeep it needs.
Here’s how the most common options compare on Long Island.
Vinyl Windows Cost

Vinyl windows are the most affordable and popular choice for homeowners.
You can expect to pay $600 to $900 per window installed for a standard vinyl replacement.
Modern vinyl windows are built with high-quality UV stabilizers to prevent the yellowing or brittleness often caused by direct sun exposure in high-sun areas across Nassau and Suffolk.
They work well for most homes and come in a range of basic color options. Since they don’t require painting or sealing, they’re a low-maintenance option that fits a lot of budgets. Vinyl windows are the best choice for homeowners looking for low maintenance and affordable windows that will last along time.
Wood Windows Cost
Wood windows sit on the higher end of the price range and are often chosen for their traditional look.
Most projects fall between $1,000 and $1,700+ per window installed.
They’re common in older or historic homes to maintain original style, but require more upkeep. You will need to continually paint these windows, and they will not withstand the elements as well as other materials. Most homes are getting rid of wood windows because of these reasons.
Fiberglass and Composite Windows Cost
Fiberglass and composite windows offer a step up in strength and durability.
Fiberglass is ideal for Long Island because it doesn’t expand and contract as much as other materials during our 90°F summers and below-freezing winters, preventing seal failure over time.
These usually range from $800 to $1,500+ per window installed, depending on the brand and configuration.
Fiberglass and composite windows withstand changing weather and allow slimmer frames. Prices can overlap wood, especially for high-end models such as Andersen 100 Series or Pella Impervia. Fiberglass and composite windows are stronger and more durable in temperatures than vinyl windows. If you are looking for the best window for your home, these are the best options on the market right now.
Aluminum Windows Cost
Aluminum windows are less common in residential homes today, but they still appear in some properties.
Costs range from $700 to $1,200 per window installed.
They have a modern look and thin frames, but aren’t as widely used in homes as vinyl or composite types. Aluminum windows are very heavy and often only used on commercial properties since they are very strong, secure, and weather-resistant. However, they are known to corrode and not be as energy efficient as other windows.
Window Cost by Style

Window style affects cost, even with the same material. Design, size, and operation all impact the final price. The glass size, window size, and type of window are big factors that play in the price.
Here’s how the most common window styles compare on Long Island.
Double-Hung Windows
Double-hung windows are the most common option in Long Island homes. You can expect to pay $600 to $1,200 per window installed, depending on size and glass options.
Casement Windows
Casement windows are hinged on the side and open outward using a crank. Pricing ranges from $700 to $1,200 per installed window. They tend to cost more than double-hung windows due to the hardware and design.
Sliding Windows
Sliding windows open horizontally and suit wider openings. Most fall within the $600 to $1,100 range per installed window. Their simple design and fewer moving parts keep costs moderate. Sliding windows can come with 2 lites or 3 lites, depending on the size.
Picture Windows
Picture windows do not open and are designed to provide a clear, unobstructed view. Costs are $800–$1,500+ per window installed, depending on size. Larger glass areas and custom sizing can push pricing higher.
Bay and Bow Windows
Bay and bow windows are larger, multi-panel units that extend outward from the home. These are priced as a full unit rather than per window, with costs ranging from $3,000 to $8,000+ installed. They need more labor and structural support, making them very expensive.
How Window Size Impacts Cost

Window size is a major price factor. Larger windows use more material, heavier glass, and more labor. Here’s how pricing breaks down based on size.
Small Windows
Small windows, often found in bathrooms, basements, or utility spaces, are the most affordable. Most fall between $500 and $800 per window installed.
These are quicker to install and use less material, which keeps costs down.
Standard Windows
Standard-sized windows are the most common in residential homes and fall right in the middle of the pricing range. Expect to pay $600–$1,200 per standard window, depending on material and style.
This category includes most double-hung, casement, and sliding windows in typical living spaces.
Large and Oversized Windows
Larger windows increase both material and labor costs. Pricing starts at $1,200 and can reach $3,000+ per large window, especially for wide or tall openings.
Heavier glass, reinforced frames, and additional support during installation all contribute to the higher cost.
Custom-Sized Windows
Custom windows are made to fit non-standard openings and often cost 20%–50% more than standard sizes, based on complexity.
Custom manufacturing, longer lead times, and detailed installation add to the final price. A custom-made window for your home is always the best option, which will allow for the best fit, increasing its energy efficiency for your home.
Glass Upgrades That Increase Window Cost

Glass upgrades change both price and performance. Standard glass is included, but upgrades cost more. To see the specific efficiency requirements for our region, you can review the ENERGY STAR guidelines for the Northern Climate Zone.
Homes in coastal towns like Freeport, Babylon, or the Hamptons face unique challenges from salt air, which can corrode hardware and wear down frames faster. We recommend hardware finishes specifically designed to resist salt spray for these South Shore properties.
For homes on the North Shore or in windier areas like Montauk, upgrading to triple-pane glass or Argon gas fills provides the extra insulation needed to block out harsh winter gusts and reduce heating bills.
Double-Pane Glass (Standard)
Most replacement windows today come with double-pane glass as the baseline.
Triple-Pane Glass
Triple-pane windows add an extra layer of glass for improved insulation and noise reduction. This upgrade adds $300 to $800 per window, depending on the brand and size.
Low-E Glass Coatings
Low-E (low emissivity) coatings are designed to reflect heat while still allowing light in. Most modern windows have Low-E coating, but advanced versions can raise costs.
Blinds Between Glass
Blinds between glass give homeowners additional privacy without having to get additional window treatments put up. This is a perfect option for homeowners who want to have added privacy without the addition of bulky or expensive window treatments.
Gas Fills (Argon or Krypton)
Many windows are filled with insulating gas between the panes to improve performance.
- Argon gas is the most common and typically included
- Krypton gas is more advanced and can increase costs.
Price differences are usually built into the window package, not shown separately.
Tempered and Safety Glass
Tempered glass is required in certain areas of the home, such as near doors, bathrooms, or low-to-the-ground windows. This upgrade can add $50 to $200 per window, depending on size and placement.
Do Window Colors and Finishes Cost More?
Color isn’t always the first thing people think about when pricing windows, but it can quietly push your total higher. Most standard windows come in white, beige, or black. These are included in the base price. Other colors cost more.
Exterior color upgrades can cost $100 to $500 per window, especially for darker finishes or specialty coatings. Interior woodgrain finishes, which mimic the look of real wood without the upkeep, also fall into that upgrade range.
Mixing interior and exterior colors adds complexity and boosts the final price. It’s a smaller cost factor, but with 10–15 windows, these upgrades add up.
Installation Costs (And What Drives Them Up)
The window itself is only part of the total cost. Installation can raise prices, especially in older Long Island homes with tricky existing conditions.
Basic Replacement Installation
In a standard setup where the existing frame is still in good shape, installation runs between $200 and $400 per window.
This type of job moves quickly. The new window fits into the existing opening with minimal adjustments.
Full Frame Replacement
Full frame replacements involve removing the entire existing window, including the frame. This type of installation falls between $400 and $800+ per window, depending on the amount of work involved.
It takes more time, material, and labor, but it also allows everything to be rebuilt properly from the inside out.
Other Factors That Can Drive the Cost Up
This is where prices can rise quickly within the same project.
- Rotten wood is one of the most common issues. Once the old window comes out, damaged framing or sills may need to be repaired or replaced before the new window can go in.
- Framing adjustments can also be necessary, especially in older homes where openings may have shifted over time.
- Interior work, like new trim or molding, adds another layer. Some homeowners keep the existing look, while others choose to update it during the install.
- On the exterior, capping is often used to protect exposed wood. This can be done in PVC, aluminum, or wood, each with its own price point.
- Homes built before certain years may also require extra steps due to older materials, which can increase labor time.
- Making the existing opening larger or smaller can be very costly. If you are making the window wider, taller, shorter, or smaller, additional labor and materials are needed. Construction work with the framing of your home or adding additional sheetrock, tape, and spackle when making an opening smaller adds additional costs
Cost Breakdown Examples (What Homeowners Actually Pay)
Looking at individual window pricing helps, but most Long Island homeowners are replacing multiple windows at once. The total project cost depends on how those individual factors come together
- A smaller, budget-focused project involving 10 standard vinyl windows typically costs between $6,000 and $9,000, assuming the existing openings are in good condition and require no repairs.
- A mid-range project using upgraded materials or larger window sizes often falls between $8,000 and $14,000 for 10 windows. This is where many homeowners land.
- Higher-end projects can climb to $12,000 to $20,000 or more for 10 windows.
That’s why per-window pricing is helpful as a baseline, but the full project scope ultimately determines the final number.
Why Window Replacement Costs More on Long Island
Homeowners on Long Island often notice that window replacement quotes come in higher than what they see online.
Older homes play a big role. Many houses across Long Island were built decades ago, and the original window frames don’t always hold up over time. Once the old windows are removed, it’s common to find worn wood, shifting openings, or areas that need rebuilding before the new windows can go in.
Labor costs also trend higher in this area. Skilled installation crews, insurance requirements, and the general cost of doing business all factor into pricing.
In some towns, permits or inspections may be required depending on the scope of work. That can add both time and cost to the project.
Exposure to the elements over the years can also impact what’s needed during installation. Homes closer to the water or in open areas show more wear around windows. Areas closer to the South Shore and coastal towns often show more wear around window openings due to long-term exposure.
Popular Window Brands on Long Island

Once homeowners get a sense of pricing, the next step is comparing brands. Different manufacturers offer their own materials, frame designs, and upgrade options, which can influence both cost and long-term performance. To help compare performance across different manufacturers, we recommend checking the NFRC ratings for U-factor and solar heat gain.
Andersen Windows (100 Series & 400 Series)
Andersen windows are widely recognized and offer a range of materials across their product lines.
The 100 Series uses Fibrex, a composite material designed to be stronger than standard vinyl. These windows fall into the mid-range price category and are a common step up from entry-level options.
The 400 Series features a wood interior and a durable exterior, placing it closer to the higher end of the price range. These are often chosen for homes where interior finish matters more.
Pella Impervia Windows
Pella Impervia windows are made from fiberglass and are known for their durability and slimmer frames.
They fall into the mid- to high-price range, depending on size and configuration. Many homeowners consider this option when they want something stronger than vinyl but don’t want to move into wood.
How Many Windows Does a Typical Long Island Home Have?
Most homes on Long Island have between 8 and 15 windows, depending on the size and layout. Smaller ranch-style homes often fall on the lower end, while larger colonials and split-level homes can have 12 or more windows. This matters because most contractors price projects as a full package, not just per window. Even small upgrades can add up quickly across a full home.
Window replacement costs on Long Island can vary widely.
Material, size, style, and installation conditions all play a role, and no two homes are exactly the same. That’s why online averages can only take you so far. The real number comes down to what’s happening behind your existing windows.
