The Fence Company: Local Commercial Fencing Serving Columbia, TN 38401

Look for rotting wood, loose or wobbly railings, popped nails, and significant warping. In Columbia's humid climate, check where posts meet the ground. If wood is soft or has advanced rot, replacement is often safer than repair. Also, if the ledger board (where the deck attaches to the house) shows signs of water damage, it needs immediate attention.

The main cause is our weather patterns. Freeze-thaw cycles and heavy rain move the clay-rich soil, loosening posts set with inadequate concrete. Poor drainage against the post base also traps moisture, accelerating rot. We solve this by digging deep holes, adding gravel for drainage, and using concrete collars that slope away from the post to shed water.

We recommend sealing or staining a new wood fence or deck within the first year, then every 2-3 years after that. Columbia's sun and high humidity break down sealers faster. If water beads up on the wood, you’re fine. If it soaks in and darkens the wood, it’s time to reapply. Power washing and applying a quality semi-transparent stain is the best approach for our local climate.
