Services
Sewer Relining
Our CIPP relining process creates a durable new pipe inside damaged sewer lines without excavation. This trenchless solution seals cracks, blocks root intrusion, and extends pipe life by 50+ years. Ideal for aging clay, cast iron, or Orangeburg pipes, the process involves video inspection, pipe cleaning, liner installation, and epoxy curing to restore structural integrity while preserving property surfaces.
Hydrojetting
Hydrojetting uses 4,000 PSI water streams to remove grease buildup, mineral scaling, and tree roots from sewer pipes. Our Ninja Drain Cleaning system combines this with specialized cutting heads to clear stubborn blockages that traditional snakes cannot handle. This non-invasive method restores full pipe capacity and prevents future clogs by thoroughly cleaning pipe walls without damaging existing infrastructure.
Video Inspection
Our high-resolution video scopes identify sewer line issues through real-time visual diagnostics. Technicians insert cameras into pipes to detect cracks, root intrusion, and collapse locations without guesswork. The system provides timestamped footage, written reports, and repair recommendations for accurate problem-solving. Homebuyers and homeowners use this service to prevent emergencies and document pipe conditions for insurance or real estate transactions.
Excavation Repair
When trenchless methods aren't viable, our targeted excavation repairs replace severely damaged sewer laterals. Using locating technology, we dig only where necessary to replace collapsed or offset pipes with durable new materials. This approach preserves landscaping while resolving structural failures that cannot be addressed through relining, ensuring long-term system functionality with minimal property disruption.
Ninja Drain Cleaning
Our proprietary drain cleaning system combines hydrojetting with specialized cutting tools to eliminate stubborn blockages. The technology removes tree roots, hardened debris, and scale buildup that cause recurring backups. Unlike traditional snakes, this method provides lasting solutions by thoroughly clearing pipe walls and preventing rapid re-clogging while maintaining pipe integrity during the cleaning process.
