How to Fix a Sagging Door (And When to Call a Pro)

A sagging door can be more than just annoying, it can cause drafts, compromise security, and damage your door frame over time. Whether it’s a residential or commercial property, a door that doesn’t close properly affects both functionality and appearance. Understanding how to fix a sagging door and knowing when to call a professional is key to maintaining a safe, comfortable, and efficient space.

With over 20 years of combined experience, Apex Door and Glass has helped homeowners and business owners in Hampton Roads resolve sagging door issues efficiently. In this guide, we’ll cover the causes, DIY fixes, and situations where professional intervention is the best solution.

1. Common Causes of a Sagging Door

Sagging doors typically result from structural or hardware issues, including:

• Loose Hinges: Over time, screws can loosen, causing the door to sag.

• Worn Hinges or Hardware: Rusted or damaged hinges can prevent the door from aligning correctly.

• Settling of the Frame: Homes and buildings naturally settle, which can shift door frames.

• Warping: Changes in humidity or temperature can cause wooden doors to warp.

• Excess Weight: Heavy doors, especially with glass panels, can pull downward and sag.

2. DIY Fixes for a Sagging Door

Some sagging doors can be corrected without professional help. Here are common solutions:

Tighten or Replace Screws

Check each hinge and tighten all screws. For long-term stability, replace short screws with 3-inch screws that anchor into the door frame, not just the trim.

Adjust Hinges

If tightening doesn’t help, you may need to adjust or replace the hinges. Sometimes simply raising the hinge slightly can lift the door back into alignment.

Shim the Hinges

Placing thin cardboard or wood shims behind the hinge plate can correct the angle of the door.

Plane the Door

If the door sticks at the frame, carefully plane down the edge that rubs against the jamb. Be cautious and remove only small amounts at a time.

Lubricate Hinges

A small amount of lubricant can improve hinge movement and reduce sticking or sagging caused by friction.

3. When to Call a Professional
