How to Successfully Install a New Exterior Door

If you're considering replacing an old, damaged outdoor door, the process is easier than expected. Ready-to-install door units, or prehung doors, simplify the installation process, saving both time and money, while boosting your home's curb appeal. Choose from materials like budget-friendly steel, long-lasting fiberglass, or classic wood that needs regular maintenance. Follow this simple guide for a perfect fit and a refreshed exterior look, ensuring your new door enhances both security and style.

Pick a high-quality prehung door in fiberglass, steel, or wood that complements your home's design.

Accurately measure the existing door, including dimensions, jamb width, and rough opening to ensure proper fit.

Carefully remove the current door using standard tools, taking care to save any usable interior trim pieces.

Examine the framing and sill area after removal, replacing damaged sections and adjusting the sill height to prevent water leaks.

Test the new door in the opening to check casing alignment with the siding.

Make necessary cuts to siding or casing, then place the door, sealing any gaps with caulk at the sill and around the casing.

Secure the door completely with nails or screws, ensuring smooth operation.

Fill gaps between the jamb and framing with foam insulation for better energy efficiency.

Finish by painting, staining, or sealing the door, jamb, and trim for a polished appearance.

Note: Prehung exterior doors are ideal for new construction or major renovations. For non-standard measurements, custom-sized doors may provide the best fit and aesthetic.
