Changing door hinges is a simple yet essential process to keep doors operating smoothly and safely. Over time, hinges may rust, loosen, or become misaligned, causing squeaking sounds, difficulty in opening, or door sagging. Whether you are upgrading to high-quality stainless steel hinges or replacing worn-out ones, understanding how to change them properly ensures long-term performance and stability.

As a professional B2B door hinge manufacturer, we provide durable, precision-engineered hinges designed for residential, commercial, and hotel applications. This guide will walk you through the correct steps to change door hinges efficiently while highlighting why using our premium products can make your installation easier and longer-lasting.

1. Tools You’ll Need

Before starting, gather the following tools:

• Screwdriver or electric drill

• New door hinges (same size as original)

• Screws (included with our hinges)

• Pencil and measuring tape

• Utility knife or chisel (for mortise adjustments, if necessary)

• Level tool or wedge for support

Our door hinge sets are pre-drilled and come with matching screws, saving installation time and ensuring a secure fit.

2. Step-by-Step Guide: How to Change Door Hinges

Step 1: Support the Door

Place a wedge or block under the door to support its weight. This prevents the door from shifting or falling when you remove the hinges.

Step 2: Remove One Hinge at a Time

It’s best to replace the hinges one by one to keep the door aligned.

• Start with the top hinge, as it carries most of the weight.

• Unscrew the hinge leaves from both the door and frame.

• Keep screws organized for reuse or comparison.

Step 3: Clean and Prepare the Area

Before installing the new hinge:

• Remove any paint buildup, dirt, or rust.

• Check that the mortise (the recessed area where the hinge fits) is smooth and clean.

• If needed, use a chisel to adjust the mortise depth so the new hinge sits flush.

Step 4: Align and Install the New Hinge

Position the new hinge exactly where the old one was.

• Use the existing screw holes if they’re still strong.

• Insert screws and tighten them evenly—avoid over-tightening to prevent stripping.

• Check that the hinge pin is aligned vertically.

Tip: If the old holes are worn out, fill them with wood plugs or toothpicks dipped in glue before re-screwing to ensure a firm grip.

Step 5: Repeat for Remaining Hinges

Follow the same process for the middle and bottom hinges. Once all are installed, open and close the door several times to confirm smooth movement and even spacing.

Step 6: Test Door Alignment

After installation, check for:

• Smooth operation without resistance.

• Equal spacing around the door edges.

• No creaking or metal friction.

If adjustments are needed, loosen the screws slightly, reposition the hinge, and retighten.
