Septic Tank Repair in Des Moines, IA

Septic Repair Across the Des Moines Metro

Most septic problems are repairable. That's the headline you won't hear from companies that make more money selling you a full system replacement. We regularly repair tanks across Des Moines, West Des Moines, Ankeny, Norwalk, and the surrounding suburbs that other companies have quoted as 'beyond repair.' Common repairs we handle every week: cracked inlet or outlet baffles, broken or sunken tank lids, missing or damaged risers, root intrusion, effluent filter replacement, distribution box repair, line breaks between tank and drain field, and partial drain field rehabilitation. Most of these come in under $1,500. Full system replacement only makes sense when the tank itself is structurally failed or the drain field is biologically dead, which is rarer than you've been led to believe.

Common Repairs and What They Cost

Baffle repair or replacement runs $250 to $600 depending on whether we can do it through the access lid or need to excavate. Riser installation is $300 to $550 and pays for itself in saved digging costs on every future service. Tank lid replacement is $200 to $450. Drain field rehabilitation (jetting, aerating, biological treatment) is $800 to $2,500 and saves homes from a $10,000-plus full drain field replacement in most cases. Full drain field replacement is $8,000 to $18,000 depending on system size, soil percolation, and county requirements. Tank replacement is $4,500 to $8,500 for a typical 1,000 to 1,500 gallon concrete tank, including excavation and permits.

How We Diagnose Before Quoting

Our repair process starts with inspection, not a quote. We open the tank, measure sludge and scum levels, inspect baffles with a camera if needed, check the distribution box, and run a hydraulic load test on the drain field if drainage is the suspected issue. We document everything with photos and measurements. Then we sit down with you and walk through what's actually wrong, what the fix costs, and what your options are. If repair is appropriate, we quote repair. If replacement is the right call, we explain why with evidence, not pressure.

When Repair Is Not Enough

Sometimes the honest answer is that a system is beyond economical repair. Signs we'd recommend replacement over repair: tank walls with structural cracks or collapse, drain field that has failed across more than 50% of its length, system that's significantly undersized for current household use, or a system that pre-dates current code and can't be brought into compliance with patches alone. In those cases, we explain the full picture, including financing options through local lenders and any cost-share programs available through Polk County's water quality programs.
