Frequently Asked Questions

A mid-range 10-window replacement project in Illinois and Iowa ranges from approximately $22,000 to $27,000. That's about $2,200 to $2,700 per window installed (2025 Cost vs. Value Report).

Your actual project cost will depend on factors such as window size and style, glass package, hardware and finish selections, and installation requirements. Because Renewal by Andersen windows are custom-made for your home, we'll provide an exact, all-inclusive quote during your free in-home consultation that's good for a full year.

The cost of replacement windows depends on several factors, including window size, style, glass package, hardware and finish selections, and the requirements of the installation. Larger windows, specialty shapes and certain design or performance upgrades can also affect the price.

Your Project Consultant will walk you through your options and explain how different selections affect the overall cost so you can make choices that fit your home, priorities and budget.

Renewal by Andersen windows can cost more than big-box store options because the investment includes both a custom-made product and a full-service replacement process. Our windows are made with durable, low-maintenance Fibrex® composite material and custom-built to fit your home's individual window openings.

The Renewal by Andersen process also brings consultation, precise measurement, manufacturing, professional installation by Certified Master Installers, and warranty service together through one company. Rather than purchasing a standard window and coordinating installation separately, you're investing in the window and the service and support behind it.

Yes. Renewal by Andersen offers a free in-home consultation to help you understand your replacement window or door options and project cost. Your Project Consultant will learn about your goals, review your existing windows or doors, discuss available styles and features, and provide pricing based on the selections you make.

Renewal by Andersen offers a variety of financing options for qualified buyers, including options that may require no money down if approved. Available financing offers and terms can vary, so your Project Consultant can explain the current options and help you determine which may work best for your project and financial needs.

Renewal by Andersen offers seven window styles: double-hung, casement, awning, sliding, picture, bay and bow, and specialty windows. You can also choose from nine exterior colors, numerous interior options including stainable wood interiors, and a variety of hardware finishes and grille patterns, creating dozens of possible combinations to complement your home.

With these options, you can match the look of your existing windows or create something new. Our team can help you compare styles, colors, finishes and other design options based on your home's architecture and how you want each window to function.

Renewal by Andersen specializes in full-service replacement of the complete window or door unit rather than glass-only replacement or individual window repairs. If you're experiencing issues such as drafts, condensation between panes, difficult operation, rotting or damaged frames, our team can evaluate whether full replacement is the right solution for your home.

Yes, in most cases we can closely complement the existing look of your home. Renewal by Andersen offers a wide range of window styles, exterior colors, interior finishes and other design options that can work with many different architectural styles.

If you're ready for a change, you can also use your window replacement project as an opportunity to update the look of your home with a different window style, color or finish.

Fibrex® material is Renewal by Andersen's exclusive composite material made from 40% reclaimed wood fiber and 60% thermoplastic polymer. The materials are permanently bonded together through an extrusion process to create a strong, durable window frame material.

Fibrex material combines the strength and stability of wood with the low-maintenance qualities of a composite. It is designed to resist rot, decay and damage from changing weather conditions without the maintenance requirements associated with traditional wood window frames.

Renewal by Andersen primarily offers double-pane windows, with triple-pane options available for select windows and doors. Both options are designed with energy performance in mind.

The right glass configuration depends on factors such as your home, window or door style, comfort goals and energy-efficiency priorities. Your Project Consultant can explain the available glass options and help determine which makes the most sense for your project.

Yes. Renewal by Andersen windows are designed to improve energy performance through a combination of insulating glass options, weather-tight construction and Fibrex® composite frames.

The right glass package can also help reduce heat transfer through your windows during both hot summers and cold winters. Actual energy savings will vary based on factors such as your existing windows, home insulation, HVAC system and energy use.

Yes. Renewal by Andersen windows are designed to perform through the changing conditions homeowners experience in Illinois and Iowa, from cold winters to hot summers, wind and significant temperature swings.

Fibrex® composite material expands and contracts less than many other window frame materials, helping the frame maintain its stability as temperatures change. Energy-efficient glass options and weather-tight construction can also help reduce drafts and heat transfer, supporting year-round comfort in a four-season climate.

Certain ENERGY STAR® certified replacement windows and doors may qualify for federal energy-efficiency tax credits when they meet current eligibility requirements. Eligibility can depend on the specific product, its energy-performance ratings, the year it is installed and current federal tax rules.

Because tax-credit requirements can change, we recommend confirming current eligibility for the specific windows or doors you select and consulting a qualified tax professional regarding your individual situation.

Yes. Renewal by Andersen windows are designed to be low-maintenance and generally require routine cleaning and keeping the window components free of dirt and debris.

Many window styles also include features that make it easier to clean the exterior glass from inside your home. Renewal by Andersen glass options include an exterior coating designed to help reduce water spots and make the glass easier to keep clean.

Installation time varies based on the number of windows or doors being replaced and the specific requirements of your project, but many projects can be completed in just one day.

Larger or more complex projects may require additional time. Before installation begins, our team will review your project and let you know what to expect for the installation schedule.

Yes. We install replacement windows throughout the year, including during the winter months in Illinois and Iowa. Our installation teams are accustomed to working through the changing weather conditions that come with a four-season climate.

Installation may be postponed or rescheduled if inclement weather could damage your home or prevent the work from being completed safely and properly.

Yes. Custom measurement is an important part of the Renewal by Andersen replacement process. Each window opening is carefully measured so your new window can be custom-manufactured to fit your home rather than relying on a standard, off-the-shelf size.

Precise measurements help support proper installation, fit and long-term window performance.

Renewal by Andersen windows are installed by Certified Master Installers who are trained specifically in Renewal by Andersen products and installation practices. Installers go through an annual recertification process to help maintain consistent installation standards.

Professional installation is an important part of the Renewal by Andersen process because even a high-quality replacement window needs to be properly measured, fitted, sealed and installed to perform as intended.

Sometimes damage around a window opening isn't visible until the existing window has been removed. If our installation team discovers rot, water damage or another issue that could affect the new window installation, they'll explain what they found and what needs to be addressed before moving forward.

The goal is to make sure the opening is properly prepared so your new window can be installed correctly rather than covering up an existing problem.

Yes. Our Certified Master Installers take precautions to help protect your home during installation, including protecting nearby floors and furniture. Once the installation is complete, the crew cleans up the work area so you're not left dealing with the mess from the project.

Yes. Removing your old windows and hauling them away is part of our replacement process. Our installation team handles removal and cleanup so you don't have to arrange separate disposal of the windows being replaced.

Renewal by Andersen replacement windows are backed by limited warranty coverage for the product and installation. Coverage includes 20 years for glass and Fibrex® material and 10 years for hardware, with installation workmanship also covered under the limited warranty.

Having product and installation coverage through Renewal by Andersen helps provide a single point of contact if you need warranty service rather than leaving you to determine whether an issue belongs with the window manufacturer or installer. Specific terms, limitations and exclusions are detailed in the written limited warranty provided with your project.

Yes. Renewal by Andersen's limited warranty can stay with the home if you sell it, allowing subsequent homeowners to benefit from applicable remaining coverage without a transfer fee.

Your local team can explain the warranty terms and remaining coverage associated with your specific windows or doors.

If you need service after your project is complete, contact your local Renewal by Andersen team. We'll help determine the issue, review whether it falls under your warranty coverage and coordinate the appropriate next steps.

Because Renewal by Andersen supports both the product and installation, you have one place to turn for service rather than having to coordinate separately with a window manufacturer and installer.

Renewal by Andersen is the full-service window and door replacement division of Andersen Corporation. While both are part of the Andersen family, Renewal by Andersen focuses specifically on the replacement process, with custom-made windows and doors, professional installation and service provided through one coordinated experience.

Andersen products available through retailers and other channels may use different product lines and purchasing or installation processes. If you're specifically looking for a full-service replacement project, that's what Renewal by Andersen is designed to provide.

Common signs that it may be time to replace your windows include noticeable drafts, difficulty opening or closing them, condensation or fogging between panes, deteriorating frames, and rooms that feel unusually hot or cold.

Older windows may also no longer provide the comfort, energy performance, appearance or functionality you want from your home. An in-home consultation can help you assess your current windows and understand your replacement options.

You don't necessarily have to replace every window in your home at once. Some homeowners complete their replacement project all at once, while others choose to replace windows in phases based on their priorities and budget.

If you're taking a phased approach, it often makes sense to start with windows that are damaged, difficult to operate, drafty or causing the greatest comfort concerns. Our team can help you think through a replacement plan that works for your home.

During your free in-home consultation, a Renewal by Andersen Project Consultant will learn about your goals and evaluate the windows or doors you're considering replacing. They'll walk you through available styles, colors, glass options, hardware and other selections, explain the installation process and take the measurements needed to prepare your project quote.

You'll have time to ask questions and compare your options before receiving an exact, written price for your project, including installation. Your quoted price is guaranteed for one full year, and there is no obligation to purchase.

Plan to set aside about 60-90 minutes for your consultation, and make sure all homeowners and decision-makers are available to participate. This gives everyone time to review the options, ask questions and discuss project pricing together.

Before the appointment, it can also be helpful to think about which windows or doors you're considering replacing and what matters most to you, such as energy efficiency, appearance, functionality or comfort. You don't need to have every detail figured out beforehand. Your Project Consultant will walk you through the available options and help you determine what makes sense for your home.
