Underground Drain Installation in Decatur, AL

Underground drain installation runs $12-25 per linear foot in Decatur, depending on soil conditions, depth, and obstacles like driveways or patios. A typical 25-foot run costs $300-600 per downspout connection. Most homes need 3-4 connections — figure $1,200-$2,400 for a complete system. Compare that to $10,000-30,000 for foundation repair. The math is clear.

For many Decatur homes, yes. Standard downspout extensions don't move water far enough from foundations already dealing with elevated groundwater. If you're within a mile of the river, in a low-lying area, or have experienced basement moisture, underground drains are likely the right solution. If you're on higher ground with good natural drainage, extensions might suffice.

Depends on your property. Options: lowest point of your yard (natural drainage), storm drain connection (where Decatur permits), dry well, or simply far enough from your home that it disperses harmlessly. For properties near the river, we design systems that work even when surface conditions are wet during flood periods.

Short term, yes — there will be trenches. We dig 4-6 inch wide channels, install pipe, and backfill. Most Decatur lawns recover within 3-4 weeks during growing season. We work around established landscaping and restore surfaces when we're done. The damage is temporary. The drainage improvement is permanent.

They don't lower your water table — nothing can do that short of relocating the Tennessee River. But they eliminate the roof drainage component. By routing that water 20+ feet away, you're only dealing with groundwater pressure, not groundwater plus thousands of gallons of roof runoff after every storm.
