When homeowners think about egress windows, the focus is often on the window itself. But the window well plays an equally important role in safety, durability, drainage, and overall appearance. In Wisconsin, where soil conditions, moisture, and freeze-thaw cycles put extra stress on belowgrade structures, choosing the right window well material matters.

Two of the most reliable and commonly installed options are corrugated steel window wells and fiberglass window wells. Each offers distinct advantages depending on budget, aesthetics, and long-term goals.

Why Window Well Selection Matters in Wisconsin
A window well is more than a retaining wall around your egress window. It must:
• Hold back soil safely
• Direct water away from the foundation
• Provide a clear, code-compliant exit path
• Withstand years of moisture, snow, and ground movement
Selecting the right material helps prevent rust, cracking, drainage problems, and premature replacement—common issues in Wisconsin basements.

Corrugated Steel Window Wells: Proven, Durable, and Cost-Effective
Corrugated steel window wells remain a popular choice for homeowners looking for strength and reliability at a practical price point. Key Benefits of Corrugated Steel
• Galvanized coating protects against rust and corrosion
• Designed to handle soil pressure and harsh weather conditions
• Long service life when properly installed
• More affordable compared to decorative options

Style & Finish Options
Corrugated steel doesn’t mean limited appearance. These window wells are available in:
• Galvanized steel
• Off-white or white finishes
• Laminated faux-rock designs for a more natural look

This makes them a strong option for homeowners who want durability without sacrificing curb appeal.
Best For:
• Budget-conscious projects
• Utility-focused basements
• Homes where durability is the top priority

Fiberglass Window Wells: Premium Strength with Enhanced Design
Fiberglass window wells are a step up in both performance and aesthetics. Designed for homeowners who want maximum durability with a finished look, fiberglass offers advantages steel simply can’t.

Key Benefits of Fiberglass
• Will not rust or corrode—ideal for long-term moisture exposure
• Strong, lightweight material engineered for below-grade use
• Available in attractive colors to complement landscaping or siding
• Molded designs that mimic stone or landscape brick

Built-In Safety & Convenience
Fiberglass window wells include a built-in ladder, improving emergency egress access while maintaining a clean, integrated appearance. This feature is especially valuable for deeper window wells and finished basements.
Best For:
• Finished or high-end basements
• Homeowners focused on long-term value
• Projects where aesthetics and safety are equally important Comparing the Two:

Which Window Well Is Right for You?

Both options meet safety requirements when installed correctly. The right choice depends on how you plan to use your basement and how important appearance and maintenance-free performance are to you.

Professional Installation Makes the Difference

Regardless of material, proper installation is critical. A professionally installed window well ensures:

• Correct depth and clearance
• Secure attachment to the foundation
• Proper drainage to prevent water buildup
• Long-term structural stability

In Wisconsin’s climate, cutting corners during installation often leads to moisture issues and costly repairs later.

Final Thoughts

Choosing between corrugated steel and fiberglass window wells isn’t about right vs. wrong—it’s about matching the solution to your home, your basement goals, and your expectations for longevity and appearance.

Both options provide safe, code-compliant support for egress windows. The key is understanding what each offers and installing it correctly from the start.
