There’s something deeply satisfying about making a door yourself — especially one that’s strong enough to face the weather and look good doing it. It’s a careful job, but with the right tools and some patience, it’s one you can absolutely tackle.
Choosing the Right Timber
Start by picking timber that can handle outdoor conditions. Good options include oak, sapele, or Douglas fir. Avoid softer woods like pine unless it’s been pressure-treated, as damp and sunlight will quickly take their toll. Choose straight, clean boards with as few knots as possible. It’ll make everything easier to work with and help the door stay stable.
Making the Frame
Your door frame needs to fit neatly into the opening, so measure carefully. Leave about 12mm (½ inch) of space on each side to allow for shimming when you install it. Cut your side jambs and head piece to length, then dry fit everything before you start fixing it together. A square, solid frame means your door will hang properly later.
Building the Door
Traditional doors are made with mortise and tenon joints — strong, tried-and-tested, and good-looking too. You can cut these joints with a router or table saw. Take your time to get a snug fit.
Next, decide on your panel layout. Raised panels suit a classic style, while flat ones give a cleaner, modern look. If you’re using solid timber panels, leave a little space for movement as the wood expands and contracts with changes in the weather.
When you’re happy with the fit, glue everything together and clamp it flat. Double-check for square — even a small twist can cause problems later.
Hardware and Finishing
Once the glue has set, it’s time to fit the hinges and cut the mortice for the lock. Hang the door in the frame to test the fit before sanding and finishing.
For outdoor protection, use a high-quality exterior finish such as spar varnish, marine varnish, or an oil-based sealer. Apply several thin coats, paying special attention to the bottom edge, where water tends to collect.
Final Touches
Building your own exterior door takes a bit of effort, but it’s worth it. You’ll end up with something strong, weatherproof, and made to last for years — not to mention the satisfaction every time you open it.
