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. 

Deck repairs cost around $800 to $3,500 . However, your cost depends on the type and severity of the repair, as well as the type of decking material you have. Other factors, like location and labor costs, impact the price, too. Boards and railings are the priciest parts of a deck to repair, while loose stairs are less expensive to fix.

Yes, but ensuring the deck has a solid foundation with adequate footings is critical before building, as the weight of a sunroom will put significant pressure on the structure below. Even if your deck is properly constructed, it may not be able to handle the extra weight. While some basic, lightweight, prefabricated sunrooms can sit on a deck with a strong existing foundation without additional supports, in many cases, the foundation and joists will need reinforcement. It is always best to have a structural engineer perform an inspection to evaluate the deck's quality and structural integrity. A professional can help you decide if reinforcement is sufficient or if it's better to tear down the deck and start over.

Composite decking requires a solid foundation, substructure, or subframe to ensure stability. This base is typically composed of posts, beams, joists, and footings. The frame's joists can be built from various materials like composite, plastic, timber, or metal, as long as the base can support the deck's weight without shifting. A professional deck builder might recommend installing the frame on a solid concrete base for added durability. The final design and materials for the substructure will depend on your budget, the type of deck, and environmental conditions.
