Frequently Asked Questions

Most homeowners replace their windows when they begin to notice issues with comfort, operation, energy efficiency or appearance. While some window problems can be repaired, older or failing windows often become more expensive to maintain and less effective at protecting your home.

You may want to consider replacement windows if:

• Your windows are difficult to open, close or lock
• You feel drafts near the windows
• You notice condensation or fog between the glass panes
• Outside noise seems more noticeable than in previous years
• Your energy bills continue to rise
• The frames are rotting, warping or deteriorating
• You’re tired of painting and maintaining older windows
• You’re updating your home’s appearance

Many Long Island homes still have windows that are 20, 30 or even 40 years old. While age alone doesn’t mean a window needs to be replaced, older windows often lack modern energy-efficient features such as Low-E glass, argon gas, advanced weatherstripping and improved frame designs.

Replacing outdated windows can help improve comfort, reduce drafts, minimize maintenance and enhance curb appeal. Many homeowners also notice quieter interiors and more consistent indoor temperatures after installing new energy-efficient windows.

For many homeowners, replacement windows are among the most worthwhile investments they can make in their homes. New windows improve comfort, energy efficiency, curb appeal and ease of maintenance while helping protect your home from the elements.

If your existing windows meet any of these conditions, replacement windows can make a noticeable difference in your day-to-day life:

• Drafty
• Difficult to operate
• Fogged between the glass
• Simply outdated

Many homeowners report more consistent indoor temperatures, fewer drafts, reduced outside noise and improved comfort throughout the year.

Beyond comfort, replacement windows can also enhance your home’s appearance inside and out. With a wide range of colors, styles and grid options available, new windows can dramatically update the look of your home and increase its curb appeal.

Modern replacement windows are also designed to require far less maintenance than older windows. Vinyl windows won’t rot, peel or require regular painting, making them an ideal choice for Long Island homeowners.

If you’re planning to stay in your home for years to come, replacement windows are often an investment that delivers value through improved comfort, appearance and performance every day.

Yes! Updating your old windows with brand-new Window World replacement windows raises the value of your home, yielding a high return on your investment.

We’re proud to offer a diverse selection of window styles for our customers. Whether you’re looking for easy-to-use functionalities, curb appeal or extended glass space, we have the style for you. Explore our window options and discover the best fit for your space.

As a homeowner, choosing a product that can withstand the elements is critical. That’s why we craft our windows using durable, vinyl frames. Vinyl stands strong against harsh weather conditions; plus, it is virtually maintenance-free for easy cleaning. The combination of functionality, beauty and affordability makes vinyl windows a popular choice for homeowners everywhere.

No. Window World does not provide repair or replacement services for window screens or broken window glass. (If you are a Window World customer, please contact us to discuss your product warranty.)

We sell both 4000 Series and 6000 Series windows. They’re both custom-manufactured vinyl replacement windows designed to improve your home’s comfort, energy efficiency and appearance. 

However, the 6000 Series is our most popular and most commonly recommended window because it offers more features, more customization selections and enhanced performance. 

The 6000 Series is considered our premium replacement window option. It features:

• A heavier-duty frame
• Thicker glass package
• Enhanced energy-efficiency options 
• A wider range of available colors, grids and customizations 
• Improved noise reduction and overall appearance. 

For these reasons, the 6000 Series is our standard recommendation for homeowners planning to stay in their home for years to come.

The 4000 Series is a quality replacement window that offers excellent value, but with fewer options and upgrades than the 6000 Series. It is a good fit for homeowners who are preparing a property for sale, updating a rental property, working within a tighter budget or simply looking for a more economical solution.

Both offer:

• Custom sizing for your home’s exact openings
• Welded vinyl frames and sashes
• Energy-efficient glass packages
• Tilt-in sashes for easy cleaning
• Professional installation
• Lifetime warranty coverage

The biggest differences come down to performance, aesthetics and available options. During your free consultation, our design consultants can demonstrate both window series side by side to help you determine which fits your goals and budget.

To lock your double-hung window, be sure to check the alignment of your locks. Your upper sash should be pushed all the way up, and your lower sash should be pushed completely down so they’re fully sealed. This will allow your locks to be secured without any obstructions.

The best replacement windows for homes in Nassau County are those that provide excellent energy efficiency, durability, and long-term value. Because every home is different, the right window depends on your goals, budget and the style of your home.

For most homeowners, vinyl replacement windows are a popular choice because they are energy-efficient, resistant to rot and corrosion and require very little maintenance. Features such as Low-E glass, argon gas, welded frames and sashes and advanced weatherstripping can help improve comfort and reduce drafts year-round.

When selecting replacement windows, it’s important to consider:

• Energy efficiency and insulation performance

Nassau County homeowners also benefit from choosing windows that can handle the area’s seasonal temperature changes, humidity, coastal conditions and occasional severe weather.

Ultimately, the best window is one that fits your home’s needs and your budget. A professional consultation can help determine which options are the best fit for your specific home.

At Window World of Long Island, our installers follow proven installation practices designed to maximize the performance, durability and energy efficiency of your new products. Every project begins with precise measurements to ensure your replacement windows, doors or siding are custom-manufactured for your home.

Throughout the installation, we work to minimize disruption to your home by protecting work areas and replacing windows one opening at a time. Before the project is complete, we review everything with the homeowner to ensure the products operate properly and meet expectations.

We also take pride in the appearance of the finished product. Our team pays close attention to interior and exterior trim details, cleanup and the overall presentation of the completed project.

In addition to quality installation practices, Window World of Long Island offers a comprehensive lifetime warranty and service support after the sale. Our goal is not simply to install new windows, doors or siding. We provide a finished project that homeowners can enjoy for years to come.

A Window World of Long Island Design Consultant will visit your home to discuss your project, inspect the areas you’re considering updating, and take preliminary measurements.

We’ll review product options, colors, styles, energy-efficient features, installation methods, warranty coverage, and financing options. We’ll also show examples of similar projects and answer any questions you may have.

At the end of the appointment, you’ll receive a detailed proposal with pricing and payment options so you can make an informed decision.

While spring and fall are the most popular seasons for home improvement, Window World provides replacement services throughout the year. In fact, Window World provides cold-weather installation during the winter months.

Most replacement window projects can be completed in one to two days, depending on the number of windows being installed and the project complexity.

For many Long Island homes, a professional Window World installation crew can replace 10 to 20 windows in a single day. Larger projects involving bay windows, bow windows, patio doors, custom trim work or structural repairs may require additional time.

During the installation process, windows are typically replaced one opening at a time. This helps minimize disruption to your home and limits exposure to outside weather. Each window is carefully installed, insulated, sealed and tested to ensure proper operation before moving on to the next opening.

Homeowners are often surprised by how quickly the process moves. In most cases, you’ll be able to use your new windows immediately after installation is complete.

On the day of your installation, it’s important to prep your space. A few things to remember:

• Move furniture away from the window or door that is being replaced
• Keep small children or pets away from the job site
• Ensure a homeowner is on-site to answer any questions or concerns

The cost of replacement windows on Long Island depends on several factors, including the size and style of the window, the glass package selected, color options and the complexity of the installation.

As a general guideline, most homeowners can expect professionally installed replacement windows to cost between $800 and $2,000+ per window, depending on the product and installation requirements. Larger picture windows, specialty shapes, bay windows, bow windows and custom configurations may cost more.

Other factors that can affect pricing include:

• Window size and style
• Interior and exterior color selections
• Grids and decorative options
• Energy-efficient glass packages
• Structural repairs or trim work
• The total number of windows being replaced

Standard white windows are generally the most economical choice. Premium exterior colors and interior woodgrain finishes typically increase the overall investment.

While Window World is a nationally recognized brand, each Window World location is independently owned and operated. Window World of Long Island is owned and managed here, allowing us to provide personalized service with the buying power, product selection and resources of America’s largest exterior remodeling company.

As a local company, we understand the unique needs of Long Island homeowners.

When comparing Window World of Long Island to other local window companies, homeowners should look beyond the initial price and evaluate the overall value being offered. Product quality, installation experience, warranty coverage, reputation and long-term service are all important factors.

One area that homeowners often overlook is warranty coverage. Before making a decision, ask every contractor:

• Will I receive a copy of the warranty before I purchase?
• What exactly is and isn’t covered?
• Are there service fees or trip charges for warranty claims?
• Is labor included? 
• Who handles warranty service if an issue arises years later?
• How easy is it to register a warranty claim?

Not all warranties are the same, and it’s important to understand the details before signing a contract. A strong warranty is generally a green flag for a good product.

Homeowners should also ask whether the quoted price includes all labor, materials and disposal. Understanding exactly what is included can help avoid surprises later in the project.

At Window World of Long Island, we believe homeowners should have a clear understanding of their products, warranty coverage and project pricing before making a decision.  We also have a beautiful showroom in Farmingdale, where you can visit to see the products, ask questions or get warranty assistance.  

Window World of Long Island stands behind its products with a comprehensive lifetime warranty designed to provide long-term peace of mind for homeowners.

Coverage varies by product, but our lifetime warranty generally covers defects in materials and workmanship on the window or door components. This can include items such as frames, sashes, hardware and insulated glass units, subject to the terms and conditions outlined in the warranty.  Many of our siding products even carry a lifetime warranty on the color!

One of the biggest benefits of our warranty is that it helps protect your investment long after the installation is complete. If a covered issue arises, our service team is available to evaluate the concern and determine the appropriate resolution.

We encourage homeowners to review the specific warranty documentation provided during their consultation, since coverage may vary by product. Our team will be happy to explain exactly what is covered and answer any questions before you make a purchasing decision.

A strong warranty is important when choosing a replacement window, entry door, patio door or siding remodeler. It reflects the manufacturer’s and our confidence in the product and our company’s commitment to customer satisfaction.
