Copper pipe corrosion is a common issue in many Marin County homes due to our water chemistry and age of plumbing systems. Signs include blue-green stains, pinprick leaks, or a drop in water pressure. We address this by conducting a thorough inspection, often using camera technology to assess the condition of pipes inside walls. If repiping is needed, we specialize in copper repiping and can discuss modern, efficient alternatives.
