Precision Meets Performance: Replacing Steel Windows with Custom Andersen 400 Series in Briarcliff Manor, New York

When you’re working on a high-end custom home—especially a renovation—there’s no room for “close enough.” Every measurement, every material, and every installation detail has to be exact. And, that was the case on a recent project in Briarcliff Manor, where an older home with original steel windows was transformed using custom-sized Andersen 400 Series windows.

The Challenge: Replacing Steel Without Compromise

The existing windows were old steel units with retractable screens—durable, but outdated in terms of performance and aesthetics. The real challenge wasn’t just replacing them—it was doing so without disturbing the existing casing and detailed stucco exterior.

Sales consultant Bruce Danback and contractor Joe Ferreira approached the project with a clear understanding: precision was everything. The team needed to measure each opening perfectly so the new windows would fit snugly within the existing structure, preserving the architectural integrity of the home.

Custom Solutions for Complex Openings

This project went beyond standard window replacement. The home featured bow windows that required additional structural consideration. To achieve a flawless installation, LVL beams were custom-ripped to an exact 8-degree angle. This level of detail ensured not only a seamless fit, but also long-term structural soundness—something every builder prioritizes.

It’s a great example of how custom fabrication and field adjustments can make or break a project, especially when dealing with older homes and non-standard openings.

Why Andersen 400 Series Was the Right Fit

For this application, the Andersen 400 Series delivered exactly what the project demanded: flexibility, performance, and aesthetics.

All windows were:

  • Custom-sized to fit existing openings precisely
  • Finished in Dark Bronze, complementing the home’s exterior
  • Designed with full divided lights for a classic architectural look
  • Built with HeatLock® I89 glass to meet current energy codes

From a builder’s perspective, one of the standout advantages was the flexibility of the 400 Series casement product line. These windows adapt well to custome-sized openings and tighter tolerances—something that’s critical when you’re working within existing conditions rather than starting from scratch.

Takeaway for Custom Builders

Projects like this highlight an important reality: the right product is only part of the equation. Execution is everything.

When you pair a versatile, high-performance window like the Andersen 400 Series with precise field measurements and skilled installation, you can confidently tackle even the most challenging renovations.

For builders working on custom homes or complex remodels, having that flexibility—both in product and process—can be the difference between a good outcome and a great one. Partner with our experienced team today – your success is our success.
