Trex decking can become slippery when wet, but it's less slippery than traditional wood decking. To enhance safety during wet or icy conditions, you can add aluminum nonslip treads to your stairs and use rock salt to prevent ice buildup. Just remember to rinse off salt residue to keep your deck looking its best.

Trex decking is water-resistant but not completely waterproof. While the boards repel moisture and resist deterioration, it's important to ensure the substructure is properly protected. Using a system like Trex RainEscape can help keep the area beneath your deck dry and prolong the life of the supporting structure. Proper installation with effective drainage and ventilation will help prevent any moisture-related issues.

Trex decking requires only minimal maintenance and is designed so that regular cleaning is sufficient to preserve its appearance. The boards need to be swept and rinsed with a sprayer to remove debris, and no sealing is necessary because the water-resistant design prevents moisture damage. Maintaining your deck with a consistent cleaning routine helps sustain its durability and visual appeal, eliminating the extra expense of sealing that wood decks incur at costs between $600 and $1,300.
