Septic Inspections
Our NAWT-certified technicians perform comprehensive septic inspections for real estate transactions and maintenance. Using advanced camera scopes, we evaluate tank integrity, leach fields, and sewer lines to identify blockages, root intrusion, or structural issues. This service ensures compliance with Boulder County SepticSmart regulations and helps prevent costly failures.
Pumping Services
Regular septic tank pumping prevents backups and extends system lifespan. We recommend pumping every 2-3 years depending on usage. Our high-powered vacuum equipment removes solids and sludge completely, ensuring optimal system performance while adhering to environmental disposal standards.
Drain Cleaning
We resolve clogged sewer lines using hydro jetting and snaking techniques. High-pressure water removes buildup and tree roots, while mechanical snakes clear immediate blockages. This service restores proper drainage for residential and commercial properties, preventing water damage and health hazards.
Sewer Camera Scope
Our sewer camera inspections identify hidden issues in pipes without excavation. A waterproof camera transmits real-time video to detect cracks, separations, or root infiltration. This non-invasive method provides accurate diagnostics for targeted repairs, saving time and reducing costs.
Septic Repairs
We handle all septic system repairs, from tank lid replacements to complete leach field restoration. Our team addresses leaks, failing drain fields, and damaged baffles using durable materials and code-compliant methods. Emergency repairs minimize property disruption and prevent environmental contamination.
