San Marcos, TX

Like much of Central Texas, San Marcos is built on expansive clay soil. This soil swells when wet and shrinks during dry periods. This constant shifting is a major concern for the older cast iron or clay sewer lines common in historic neighborhoods. The movement can cause pipes to crack, separate, or shift out of alignment, leading to significant clogs, slow drains, or even slab leaks. For this reason, we often recommend a plumbing inspection with a camera to check the condition of these older lines, especially before buying a home.

San Marcos's large student population, for example, can contribute to specific plumbing issues. Apartment complexes and older rental properties, in particular, frequently experience drain clogs from hair and grease buildup. Furthermore, foreign objects accidentally flushed down toilets, from hygiene products to small items, are a common cause of blockages. As a result, this can affect not only a single unit but entire buildings. While some minor clogs can be fixed with a plunger, however, severe or recurring blockages often indicate a deeper issue that requires professional attention, especially if they are impacting a building's main sewer line.
