Services
Septic Tank Pumping
Our septic tank pumping service removes solids and liquids using high-capacity trucks (1,500+ gallons) while spraying tank interiors for thorough cleaning. Technicians assess system functionality during service, identifying potential issues like clogs or structural damage. Homeowners should schedule pumping every 2-3 years, though frequency depends on tank size and household usage. Emergency services address backups, odors, or pooling water immediately.
System Installation
We design and install complete septic systems for new constructions or replacements, including tanks, drainfields, and leach lines. Our team handles permits, health inspections, and code compliance while offering durable fiberglass/concrete tank options. Installations include restaurant grease traps and commercial clarifiers, with system layouts optimized for property size and usage patterns. Post-installation warranties ensure long-term performance.
Repairs
Our technicians diagnose failing systems through visual inspections and camera line assessments, addressing cracked baffles, root intrusion, or saturated drainfields. Common repairs include riser replacements, distribution box fixes, and seepage pit reconstructions. Free estimates apply to exposed tanks, with labor fees for buried tank excavations. Emergency repairs prioritize urgent health hazards.
Inspections
We conduct comprehensive septic inspections for real estate transactions, measuring tank integrity, leach field conditions, and hydraulic efficiency. Services include water testing, camera line diagnostics, and compliance documentation for lenders. Inspections typically schedule within 1-3 business days, with reports submitted promptly for escrow purposes.
Tank Locating
Using specialized tools, we locate buried septic tanks with 90% accuracy, even under new construction or overgrown vegetation. If we cannot identify the tank location, no charge applies. Services include lid exposure for easier future access, with no additional fee for secondary lid corrections during scheduled pumping visits.
