In most cases, sanding an old deck before staining it is necessary to achieve a decent finish. If your old deck has a relatively new stain finish on it and you're only doing touch-ups, you can generally skip the sanding part. However, if your goal is to make the deck look and function better, sanding first is a must. 

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.

You should refinish your deck to maintain its appearance, durability, and longevity. Refinishing your deck protects the wood from foot traffic and the elements. It also helps extend its life span by keeping rot, mildew, and termites at bay. By maintaining your deck, you can avoid the cost of replacing your deck sooner. A refinished deck also looks great and restores some of its original beauty.

Both aluminum and composite decking materials are environmentally friendly, with aluminum decking coming in as the most eco-friendly option. 

Though composite decking helps remove plastics from landfills, recycles wood, and lasts longer than traditional wood decks, it’s not recyclable and only lasts for 25 to 30 years on average. Aluminum can last well over 30 years and is almost always recyclable.
