Sewer Line Repair
Coronado Excavation provides expert sewer line repair services for residential, commercial, and municipal clients. Our technicians use advanced diagnostics to identify issues like root intrusion, pipe corrosion, and blockages. We offer both traditional excavation and trenchless repair methods to minimize property disruption while ensuring long-lasting solutions. All repairs come with a five-year warranty.
Water Line Replacement
We specialize in water line replacement for damaged or aging underground pipes. Our team addresses issues caused by freezing, tree roots, and soil shifts using minimally invasive techniques. Emergency services are available 24/7, with same-day diagnostics and transparent pricing. All installations meet local code requirements and include a five-year warranty.
Trenchless Sewer Replacement
Trenchless sewer replacement eliminates the need for extensive excavation by creating new pipes within existing damaged lines. This method preserves landscaping and reduces project timelines. Coronado Excavation uses hydraulic equipment to install durable HDPE pipes, offering a cost-effective alternative to traditional dig-and-replace methods with minimal disruption to property.
Sewer Video Inspection
Our sewer video inspection service uses high-resolution cameras to diagnose underground pipe issues without destructive digging. Technicians identify cracks, blockages, and root intrusion while providing real-time visual feedback. Clients receive a recorded video link for reference. This non-invasive method ensures accurate diagnoses and targeted repair recommendations.
Emergency Drain Cleaning
Available 24/7 for urgent drain clogs and sewer backups, our emergency team responds promptly to residential and commercial properties. Using high-powered snaking equipment and hydro-jetting, we clear blockages caused by grease buildup, foreign objects, and root infiltration. Preventative maintenance services help avoid future emergencies while extending system lifespan.
