Step 1: Measure for a Custom Fit
Because many older homes were built with non-standard door openings, the installation process begins with detailed measurements. A professional installer measures the width, height, jamb depth, and wall thickness to ensure the replacement door is custom-manufactured to fit your home's existing opening. Accurate measurements help minimize gaps, improve energy efficiency, and ensure smooth operation.
Step 2: Remove the Existing Door and Inspect the Opening
Once the new door is ready, the existing door and frame are carefully removed. Before the new unit is installed, the exposed framing is thoroughly inspected for signs of wood rot, insect damage, moisture intrusion, or structural issues. Identifying and correcting these problems before installation helps create a solid foundation for the new door and prevents future issues.
Step 3: Install and Level the New Door
The replacement door is carefully positioned within the opening and secured using shims. Installers make precise adjustments until the door is perfectly square, level, and plumb. Proper alignment is critical to ensure the door opens and closes smoothly, locks securely, and creates a consistent weather-tight seal around the entire frame.
Step 4: Flash and Seal Against Water Intrusion
Protecting your home from moisture is an important part of the installation process. The door sill is properly flashed and sealed to direct water away from the opening and reduce the risk of leaks. Additional sealants and weatherproofing materials are applied where needed to help improve the door's long-term performance and weather resistance.
Step 5: Install the Hardware
After the door has been secured, the hardware is installed and adjusted. This includes the lockset, deadbolt, handles, hinges, and any optional features such as a digital keypad or smart lock. Each component is tested to ensure smooth operation, reliable security, and proper alignment.
Step 6: Finish the Door for Long-Term Protection
If the replacement door was not prefinished by the manufacturer, it should be painted or stained as soon as possible after installation. The finish should completely cover the exterior, interior, top, bottom, and both side edges of the door. Proper finishing protects the door from moisture and UV exposure while also satisfying most manufacturer warranty requirements.
