How Much Do Infinity by Marvin Windows Cost in Georgia? A 2025 Pricing Guide
For Georgia homeowners, the question "How much do new windows cost?" is the first step in a significant home upgrade. Buying Infinity by Marvin fiberglass windows is a smart investment, not a simple purchase. What you're paying for is the custom craftsmanship, superior materials, and long-term value that make these a premium product.
For a comprehensive replacement of a standard-size Infinity by Marvin window in Georgia, you can generally expect the investment to range from $1,500 to $2,500. This price point reflects a significant upgrade in quality and performance compared to other basic windows such as vinyl or wood.
We believe transparency is essential, which is why we created this guide to provide a clear and honest breakdown of the costs associated with a premium window replacement. Here, we will explain the factors that determine your final investment, answer the most common questions about the cost, and explore the flexible options we offer to make the project fit your budget.
Decoding Your Investment: The Factors That Define Your Price
The primary reason there is no "one-size-fits-all" price is that every Infinity by Marvin window we install is custom-manufactured for your home's unique openings. This commitment to a perfect fit is the foundation of a successful window replacement. The final quote for your project is a reflection of three critical components:
Your Custom-Made Infinity by Marvin Window: The foundation of the investment is the window itself. Your specific selections tailor the cost, including:
Precise Size and Shape: The cost begins with the exact dimensions of each window.
Window Style: The functional design, such as a double-hung, casement, or picture window, is a key factor in the price.
Performance Package: You can customize energy efficiency with different Low-E glass coatings and gas-fill options.
Aesthetic Details: You personalize the final look with choices in colors, grille patterns, and hardware finishes.
The Expert Installation Process: A premium window only performs as well as it's installed. Our price includes a meticulous installation process, where our dedicated, high skilled installation teams ensure a perfect, weathertight seal. We specialize in precision, whether we are doing a full-frame or insert window replacement.
An Unmatched Dual Warranty: Your investment is protected by two powerful warranties: the Limited Lifetime Warranty on the Infinity by Marvin product itself, and our exclusive Lifetime Service Warranty that covers the installation for as long as you own your home.

Common Questions About Window Replacement Costs
Can't you just give me a ballpark figure for a plain, regular window?
We understand the need for a straightforward number to help you budget. For a premium, custom-made Infinity by Marvin window, which includes our comprehensive, detailed installation, the ballpark investment typically starts around $1,500 and can go up from there. This investment reflects a significant upgrade from a "plain" window. Infinity by Marvin fiberglass windows are designed to be beautiful, not big and bulky like vinyl composite windows. The investment covers a premium, custom-manufactured window, a detailed installation that is quick, clean, and hassle-free, and our exclusive dual lifetime warranties.
What's the price per window?
The price per window generally falls between $1,500 and $2,500, but the final cost is determined by your custom selections. The main factors influencing the price are the window's size, style, and your choice of colors, hardware, and performance glass. This investment allows you to brighten your home with more daylight and bigger views, as the strength of fiberglass allows for narrower, less bulky frames than vinyl.
Do you replace just one window or do I have to do the whole house?
You can absolutely replace just one window. Our goal is to make window shopping simple, which is why we have no minimum window requirement. This approach is part of our commitment to a stress-free experience for homeowners. Many of our clients start small and complete their projects in phases using our Price Lock Guarantee, which locks in your product pricing for 36 months.
How do your prices compare to other brands/companies?
Our prices are considered middle-of-the-road, positioned above standard vinyl windows but below some of the most expensive wood composite brands. We believe this price point reflects the perfect balance between a premium product, superior performance, and long-term value.
While the initial investment for Infinity by Marvin fiberglass windows is higher than for a standard vinyl window, the long-term value is significantly greater. The difference comes down to the material itself:
Superior Strength: Infinity's Ultrex fiberglass is 8x stronger than vinyl, resisting bending and flexing to protect the integrity of your home.
More Glass: Because of its strength, Infinity by Marvin windows have slimmer profiles, offering you more daylight and bigger views.
A Finish That Lasts: This finish is engineered for Georgia's climate. Infinity's proprietary acrylic finish is 3x thicker than the competition, resisting scratches and dents. It performs so well that even dark colors won't fade or suffer UV degradation.
