Fresno Iron Works | Trusted Fencing Company in San Antonio, TX

The primary cause is the expansive clay soil common in areas like Alamo Heights and near the San Antonio River. This soil swells when wet and shrinks during dry spells, leading to movement that loosens posts. Fresno Iron Works counteracts this with deeper-set posts and reinforced concrete footings.

Look for rust spots, bent rails, or sections pulling away from posts—often near overgrown shrubs or trees in neighborhoods like Olmos Park. Roots can push against base plates, and vines retain moisture, accelerating corrosion. Fresno Iron Works offers regular maintenance and galvanized coatings to prevent such damage.

Installing a continuous concrete curb around the fence base helps, as does using corrosion-resistant materials like galvanized steel or aluminum. Fresno Iron Works designs custom solutions, including drainage-friendly post bases, tailored to San Antonio’s soil conditions.
