How to Fix a Sticky Door: A DIY Guide
Is your door refusing to close without a forceful slam? Those stubborn sticky doors can be more than just an annoyance – they can damage your doorframe and create unsightly paint wear over time. Fortunately, fixing a sticky door is a manageable DIY project that can save you money on professional repairs.
Essential Tools
Before starting your door repair project, gather some basic tools. These might include:
- Jack plane or smoothing plane
- Block plane (particularly useful for detail work)
- Electric plane (a cost-effective alternative to traditional hand planes)
- Wood chisels (19mm and 25mm are most common)
- Various screwdrivers (flathead and Phillips head)
- Hammer
Identifying the Problem
A sticky door often shows clear signs of where it’s rubbing:
- Paint wear on the top or sides of the door
- Uneven gaps between the door and frame
- Need for extra force to close the door
- Visible rubbing marks on the frame
The ideal gap between a door and its frame should be approximately 2mm all around. Anything less can cause sticking, while anything more might affect the door’s functionality. If you plane too much off in the winter, you may find that when the wood dries in the summer, your gap is too big.

Step-by-Step Repair Process
- Initial Assessment
- Check where the door is sticking by looking for paint wear and rubbing marks
- Measure the existing gaps around the door
- Identify areas that need adjustment (in this case, we didn’t need to remove the door)
- Identify tools that will best fit the job. In this case, we decided to use the electric plane and block plane. See this blog for the jack plane and chisels.
- Planing the Door
- Start with minimal adjustments (about 0.5mm at a time)
- Focus on problem areas first
- Check the door’s fit frequently during the process
- Aim for an even 2mm gap all around
- Fine-Tuning
- Reduce the planing depth to 0.25mm for final adjustments
- Ensure even gaps on all sides
- Test the door’s movement repeatedly
- Finishing Touches
- Use a block plane to remove sharp edges (known as the Harris edge)
- This serves two important purposes:
- Prevents finger cuts if someone catches their hand in the door
- Prevents paint beading and running during future paint jobs
Pro Tips
- Always start with minimal adjustments – you can remove more material, but you can’t put it back
- Electric planes can be more cost-effective than traditional jack planes, but are not always the best tool for the job. See this blog for using the jack plane.
- Regular door maintenance can prevent severe sticking issues
- Consider the seasonal changes in wood expansion and contraction when making adjustments.
By following these steps, you can transform a troublesome sticky door into one that closes smoothly and safely. This simple DIY fix not only improves your home’s functionality but also helps maintain your doors’ longevity and appearance.
Remember: While door planing might seem intimidating at first, it’s a valuable skill that can save you money on home maintenance in the long run.
