Southern Exteriors: Expert Fence Installation Serving Seymour, TN 37865

The main cause is prolonged contact with moisture in the red clay soil common in Seymour, especially near wet areas like the Little River watershed. Without proper drainage, wood posts absorb water and decay within a few seasons. Southern Exteriors prevents this by using pressure-treated lumber or cedar, plus gravel backfill around posts to shed water away.

Look for soft or spongy wood when prodded with a screwdriver, cracked or splintered boards near the house side, and loose railings. In Seymour, decks facing east often show mold faster due to morning shade. Southern Exteriors can assess if a repair suffices or full replacement is safer, especially for structures over 15 years old.

For new installations, we dig wider holes and add 6-8 inches of gravel at the base. Then we set the post and backfill with a dry concrete mix, which lets rainwater drain away from the wood. For existing posts, we can install a metal post sleeve or replace the rotted section with a concrete anchor system, common near areas like the Seymour Heights neighborhood.
