How to Build a Gate: A Step-by-Step Guide

What’s the proper spacing between gate posts for optimal gate operation?

The proper spacing between gate posts should be the exact width of the gate itself, plus an additional allowance of 1/2 to 3/4 inches on either side for hinges and hardware, ensuring smooth operation and preventing binding. This yields a total gap of 1 to 1 1/2 inches wider than the gate’s actual width between the posts.

Achieving the correct spacing is critical for a gate that swings freely and latches securely. If the gap is too small, the gate will bind against the posts, making it difficult to open and close, and potentially damaging the gate or posts over time. Conversely, if the gap is too large, the gate may sag or swing unevenly, leading to latching problems and a less secure closure. Remember to account for the thickness of any shims or leveling materials that may be needed during installation to ensure the posts are perfectly plumb. Several factors influence the final required spacing beyond the basic hinge allowance. The type of hinges being used (butt hinges, strap hinges, etc.) impacts the needed space. Larger, more robust hinges typically require slightly more clearance. Also, consider the possibility of post movement due to ground settling or frost heave, especially in colder climates. Allowing for a small degree of potential movement during the initial installation will help prevent future operational issues. Accurate measurements before you dig the post holes is vital to avoid costly corrections later.

What’s the best way to treat the wood to protect my gate from rot and insects?

The best way to protect your wood gate from rot and insects is to apply a multi-pronged approach, starting with pressure-treated lumber for the frame and rot-resistant wood like cedar or redwood for the pickets. Follow this by applying a high-quality wood preservative, sealant, or stain with UV protection, and maintaining the finish with regular inspections and reapplication as needed.

Pressure-treated lumber is infused with chemicals that make it highly resistant to decay and insect infestation. While it’s ideal for the gate’s frame, which is closest to the ground and most susceptible to moisture, using naturally rot-resistant woods such as cedar, redwood, cypress, or even thermally modified wood for the pickets adds an extra layer of defense and aesthetic appeal. These woods contain natural oils that deter insects and resist moisture absorption. Always choose lumber that is rated for ground contact if it will be touching the ground. After construction, apply a high-quality wood preservative containing ingredients like copper azole or borate. These penetrate the wood fibers and provide long-lasting protection. A sealant or stain with UV protection is crucial for preventing sun damage and water penetration, both of which contribute to wood rot and cracking. Regular inspection is key. Look for signs of damage, like soft spots, discoloration, or insect activity. Depending on the product and exposure to the elements, reapply the sealant or stain every one to three years to maintain optimal protection. Pay special attention to end grain, joints, and any areas where water tends to pool.

And that’s all there is to it! Hopefully, this guide has given you the confidence to tackle your gate-building project.
