The water supply serving San Marcos, TX carries its own characteristics - mineral content, pH, and hardness levels that vary by source and season.

We recommend annual water heater maintenance for most San Marcos, TX homes as a basic cost-saving measure.
Tree canopy is a part of what makes many San Marcos, TX neighborhoods desirable - but mature trees mean mature root systems, and root intrusion into older clay or cast iron sewer lines is among the most common and recurring drain problems our San Marcos, TX teams encounter.
