Viking Exterior Services STL: Professional Residential Fencing Serving Saint Louis, MO 63123

St. Louis’s climate—with high humidity, heavy rain, and freeze-thaw cycles—causes wood to rot, warp, and split faster than in drier regions. Fence posts can shift in clay soil, and constant moisture promotes mold and insect damage. Our team inspects for these common issues and uses rot-resistant materials like cedar or composite to prevent future problems.

Look for extensive rot that goes deep into the joists, wobbly railings, cracked support beams, or a spongy surface. If more than 30% of your deck is decayed, replacement is often safer and more cost-effective long-term. We can assess the structure for free and recommend the best approach.

Regular pressure washing removes built-up dirt, mold, and mildew that trap moisture and cause decay. It also prep surfaces for sealing or staining, extending the life of your wood. We use gentle pressure to avoid damaging fibers—ideal for St. Louis’s humid weather.
