Polybutylene Pipe Replacement in San Francisco
Many homes built in the 1980s and 1990s may have polybutylene pipes, which are prone to sudden failure due to their material composition.

We focus on safely removing and replacing these problem pipes with modern, durable alternatives, preventing future leaks in San Francisco.
Main Water Line Repair in San Francisco
Your main water line runs from the meter box to the house and is under constant pressure. When it leaks, you may notice a spinning meter dial with all fixtures off, low pressure or a wet spot that never dries. We locate the leak, expose the pipe and splice in a new section with approved fittings. If the line is old galvanized or polybutylene, we will recommend a full replacement before more breaks happen.

Sewer line damage underground can show up as foul odors, slow drains or soggy spots in your yard. We diagnose breaks, blockages or collapses in your main sewer line using advanced camera inspections.
