Maintenance

Add Correct Gap Spacing Between Boards

Always leave a 1/8 inch minimum gap between boards to allow natural expansion during Missouri's wet seasons.

Use Corrosion-Resistant Fasteners Only

Use exterior-rated corrosion-resistant screws or hot-dipped galvanized nails to prevent rust staining and fastener failure.

Seal the Deck Surface Promptly

Apply a quality water-based deck sealer shortly after installation to protect the surface and extend board life.

Ensure Proper Substructure Ventilation

Keep joists at least 18 inches off the ground to allow airflow and reduce long-term moisture buildup beneath the deck.

Treat All Cut Ends on Site

Apply an approved end-cut preservative to every freshly cut board end to maintain full rot protection across the finished deck.
