GM Construction - North Charleston's Top-Rated Fence Builders

Common signs include rotting or splintering wood, loose or rusted nails and screws, and visible sagging or wobbling. In North Charleston's humid coastal environment, you may also see mildew growth, warped boards, or soft spots from water damage. If your deck's posts are shifting or the railing feels unstable—especially after a storm—it's time for a professional inspection.

The main causes are high humidity, salt spray from the nearby coast, and periods of heavy rain typical of this region. These conditions accelerate wood rot, rust on metal hardware, and paint peeling. Without proper sealing or weather-resistant materials, a fence can warp or weaken within a few years. GM Construction uses treated lumber and corrosion-resistant fasteners to extend your fence's life.

We offer full deck repair and replacement services. First, we inspect the structure for hidden damage like cracked joists or compromised supports. Then we replace rotted or broken boards, reinforce shaky railings, and re-secure the deck to your home. For severe damage, we recommend a full replacement with durable composite or pressure-treated wood designed to withstand local weather. We serve all North Charleston neighborhoods, from the Charleston Navy Yard area to the Coosaw Creek Country Club.
