Staining and sealing the underside of a deck creates a moisture barrier but traps water in the boards, quickly leading to rot. No matter how well you seal the above deck, water still gets through via nails and screw heads on the surface. Allow this water to flow naturally under the deck, where it is routed through the drainage system.

The best direction for a gate to swing depends on its location and purpose, but swinging inward is the general rule. An inward swing is often considered safer, prevents the gate from opening into public spaces like a sidewalk, and may be required by local building codes.

There are exceptions and specific considerations. If your property is on a slope, an inward swing might not be possible. For a deck gate, it's safest to have it swing away from any steps. In a backyard, the direction can be a matter of preference, though an inward swing can be helpful when carrying heavy items like a wheelbarrow into a garden.

Regardless of direction, ensure the gate can open fully without hitting any objects or blocking spaces. While an inward swing is standard, a gate that can swing both in and out offers the most flexibility if your setup allows for it.

Building codes for deck railings can vary by location, so it's important to consult your local regulations before construction. Generally, a guardrail is required for any deck that is more than 30 inches above the ground.

For residential properties, the standard minimum height for a deck railing is 36 inches. However, some states and municipalities have stricter requirements; for example, California and Washington mandate railings that are at least 42 inches high. Therefore, a 42-inch railing is not considered too high and may be required in your area or chosen voluntarily for additional safety.

In addition to height requirements, codes also specify other safety features, such as the maximum spacing between balusters to ensure they are close enough to prevent a child from squeezing through.

If you want to make a deck cleaner from products already in your home, there are various options. The most common is to use a gentle blend of 1 gallon of warm water and 2 tablespoons of ammonia-free dish soap. You can also mix water with distilled vinegar. Sprinkling on some baking soda can help to remove mold and mildew. You can add oxygen bleach (but never damaging chlorine bleach) to the water and ammonia-free dish soap solution for something a bit stronger.
