Excavation & Major Line Work
Full excavation services for water lines, sewer mains, and underground plumbing.
When the Big Jobs Need Doing
Some plumbing problems require getting underground — whether it’s a collapsed sewer main, a deteriorated water service line, or foundation drainage that needs replacement. David Mechanical has the equipment, experience, and licensing to handle major excavation projects for residential and commercial properties.
Water Main Replacement
If your water service line from the street to your home is leaking, corroded, or made of outdated materials like lead or polybutylene, replacement is necessary. We excavate the old line, install a new copper or HDPE water service, and coordinate the connection with your municipal water department.
Sewer Line Excavation
While we prefer trenchless methods when possible, some situations require traditional excavation — severely collapsed pipes, major bellies, or lines that need rerouting. We have the equipment to handle residential sewer excavation at any depth, and we work efficiently to minimize the time your yard is open.
Proper Permitting and Safety
All excavation work requires proper permits and utility locates. We handle the entire process — coordinating JULIE utility marking, pulling municipal permits, scheduling inspections, and ensuring every aspect of the project meets code. Safety is never compromised on a David Mechanical excavation project.
