Step-by-Step Guide to Hang Exterior Door

Hanging an exterior door involves several key steps, including preparing the door frame, installing hinges, and securing the door. Follow these steps carefully for a successful installation.
Preparing the Door Frame
- Clean the opening thoroughly, removing debris and old caulk. Ensure the subsill is level; adjust if necessary.
- Install a drip cap or Z-flashing above the opening to prevent water intrusion. Position the top leg behind the house wrap or tar paper, which lies behind the siding.
- Apply a bead of high-quality exterior caulk along the exposed framing where the new door’s trim meets the wall, and across the floor where the door’s threshold will sit.
Installing the Door Hinges
- Select the correct hinge size for your door’s weight. Standard exterior doors typically require three hinges for optimal support.
- Mark the hinge locations on both the door and the door frame. Generally, place hinges at 7 inches from the top and 11 inches from the bottom, with the third hinge centered between them.
- Cut hinge mortises on both the door and frame using a chisel. This creates a recessed area that allows the hinge to sit flush with the surface.
- Attach the hinges to the door first, then secure them to the frame using appropriate screws. Ensure all screws are tightened fully for stability.
- Position the door into the opening, aligning it with the frame. Use shims to adjust the door until it hangs straight and level.
- Check for proper gap spacing around the door frame; gaps should be consistent for effective sealing and operation.
- Once aligned, secure the door by attaching it to the frame’s hinges. Test the door’s functionality by opening and closing it several times.
- Add weather stripping around the door frame to enhance insulation and prevent drafts. This step improves energy efficiency and prolongs door life.
Tips for a Successful Installation

You enhance your exterior door installation by avoiding common mistakes and following maintenance tips. Keeping these recommendations in mind ensures longevity, security, and optimal performance for your new door.
Common Mistakes to Avoid
- Ignoring Measurements: Measure the door opening accurately at the top, middle, and bottom. Rely on the smallest height measurement for a snug fit to avoid alignment issues.
- Neglecting Leveling: Ensure the door frame is perfectly plumb and level before securing it. Uneven installations lead to operating difficulties and increased wear on the door.
- Skipping the Test Fit: Always test fit your prehung door. Check for proper alignment, smooth operation, and tight weather stripping seals before finalizing the installation.
- Overlooking Weather Stripping: Install weather stripping properly to prevent air leaks. Proper seals improve energy efficiency and reduce heating and cooling costs.
- Regular Inspection: Inspect your door every six months for signs of wear or damage. Look for cracks, peeling paint, or gaps around the frame, addressing issues promptly.
- Seal Gaps: Reapply caulk as needed to maintain waterproofing. Ensure all gaps between the door and frame remain sealed to prevent water damage.
- Lubricate Hinges: Apply lubricant to hinges every six months. Lubrication maintains smooth operation and prevents squeaking.
- Clean the Surface: Wash the exterior door regularly with mild soap and water. Keeping the surface clean preserves its appearance and extends its life.
- Check the Weather Stripping: Periodically test weather stripping for effectiveness. Replace worn or damaged strips to maintain energy efficiency.
