Now, to address the above possible problems, here is what you can do.
1. Keep your lawn maintained and especially the area around the gate path. If you have dogs, you may want to place a few pavers under the closed gate to keep them from wanting to dig there.
2. Inspect the fence job and all the fencing around the gate to make sure the wood looks solid and that everything is fastened correctly.
3. Make sure the gate posts are set with plenty of concrete and it is allowed to set up good before gate installation.
4. Demand better hardware from your fence company with a stainless steel or zinc latch and hinges.
5. Have the installation company draw you a sketch of how the gate will be built. This is crucial because this is a short-cut area by many companies and will be your most vulnerable part of the construction. Question the design if you have concerns.
