Pipe Repair vs Full Repiping in San Marcos

Many San Marcos homeowners choose repiping with PEX because it is flexible and resistant to our local water chemistry.

Water Line Repair and Replacement Services in San Marcos

Water line replacement restores strong pressure and eliminates leaks between the street and your home. We handle both the service line and main line work with attention to local soil conditions and proper backfill so the new line lasts for decades.
