Rot loves moisture, so deck rot typically impacts the parts of a board that stay wet. This includes the underside of boards, in addition to support posts and joists. However, any part of a board can rot, given the right conditions. 

Yes, it is possible to build a small, basic deck for $5,000, particularly if you use less expensive materials and a simple design. To stay within this budget, consider a size under 10x12 feet and use affordable materials like pressure-treated wood or cedar. While the general cost for deck building ranges from $4,350 to $12,560, with an average around $8,200, some projects can be completed for as little as $4,350. You can also save on labor costs by doing the work yourself, but be aware that mistakes could end up costing more than hiring a professional. A contractor may have a higher upfront cost, but they can ensure a safe, stable deck that will last.

Ideally, a gate should be able to swing both in and out. However, if it can only open in one direction, it is generally best for it to swing inward. This is often the safest option, especially for deck gates near steps, as you'll want the gate to swing away from the stairs. An inward swing also prevents the gate from opening into a public space, like a sidewalk, and can be more convenient when carrying heavy items like a wheelbarrow into a garden.

There are exceptions, however. The layout of your property may require a different approach. For example, if your property is on a slope, the gate may not be able to swing inward. You should also ensure the gate can open fully without colliding with any objects or blocking access to other areas. For a backyard garden gate where public access isn't a concern, the direction it swings is largely a matter of personal preference. Finally, always check your local building codes, as they may have specific requirements for which way a gate must swing.

In most cases, your deck will need some form of deck footing to hold it in place, preventing moisture from rotting your wood and decreasing your deck’s lifespan. Concrete deck blocks are the most common type of footing for floating decks. Some homeowners use ground-level deck footings. For added security, consider digging and laying your ground-level footings below ground.
