Frequently Asked Questions

Common questions about custom/specialty windows in Raleigh, NC.

Full-frame replacement in Raleigh involves removing the entire sash, frame, and exterior trim down to the rough structural opening, whereas pocket replacement slides a new unit into existing jambs. For custom and specialty shapes like arches and trapezoids, full-frame replacement is almost always recommended to inspect the underlying framing for hidden wood rot and ensure critical sill pan flashing is properly integrated.

Why Proper Specialty Window Construction Matters in Raleigh

Non-standard window shapes face severe structural and thermal stresses during severe Piedmont thunderstorms and humid heatwaves. Ill-fitting stock windows crammed into specialty openings require excessive shimming and caulking, inevitably inviting water leaks, rotten sills, and air drafts behind the siding. Our custom-fabricated specialty windows integrate self-adhering sill pan flashing membranes and waterproof perimeter seals, ensuring your home remains protected, watertight, and architecturally striking for decades.
