Northwest Ohio is the old Great Black Swamp. The lake plain is flat, the clay is dense, and infiltration rates are low enough that a half-inch rain can sit on the surface for two days. Add a builder who graded the lot toward the house and downspouts dumping four feet from the block, and you get exactly what most of our drainage clients describe: a soft corner that never dries, a basement wall that weeps every spring, and grass that keeps dying in the same spot.
We diagnose before we dig. Where the water comes from, where it currently goes, and where it can legally and physically be sent are three separate questions, and the answer changes the design completely.
The drainage problems we solve most often here
If you recognize two or more of these, the yard is telling you something structural.
Standing water 24 hours after rain
Puddles that linger a full day mean the ground is not accepting water and there is no path off the surface. This kills turf roots, invites moss, and breeds mosquitoes by July.
Water against the foundation
Soil that has settled toward the house, mulch mounded above the sill, or a downspout discharging at the corner. This is the fastest path to a wet basement and the cheapest one to fix.
Ruts, erosion channels and washed mulch
Concentrated flow. Something upstream — a neighbor's gutter, a driveway, a roof valley — is dumping volume into a path it carved itself. Spreading that flow out is usually the fix.
A soft, spongy low spot that never firms up
Either a perched water table over clay or a buried tile line that has collapsed. Old farm tile runs under a lot of properties in Defiance, Paulding and Williams counties and it does fail.
Sump pump running constantly
Surface water is reaching the foundation drain because it never had anywhere else to go. Handling it at the surface takes the load off the pump.
Drainage systems we install
French drains
A trench with perforated pipe bedded in washed stone and wrapped in filter fabric, intercepting subsurface water and carrying it to a discharge point. Correctly built, they run for decades. Built without fabric, they silt shut in a few years.
Downspout burial and pop-up emitters
The highest-return drainage work there is. Solid, non-perforated pipe from each downspout, pitched, carried well away from the foundation, and terminated at a pop-up emitter or a daylight outlet.
Catch basins and surface inlets
For low spots that collect surface water, a grated basin tied into solid pipe removes ponding without regrading the entire yard.
Swales and dry creek beds
A shaped, gently pitched channel that carries volume across a property. Lined with stone it becomes a dry creek bed — a drainage structure that looks like a design feature.
Regrading and positive slope correction
The ground within ten feet of your foundation should fall roughly six inches. Where settlement has reversed that, we cut, fill and re-establish positive drainage, then restore turf.
Rain gardens and infiltration areas
A planted depression that captures runoff and lets it soak in over a day or two, planted with species that tolerate both saturation and drought. Handles volume, filters runoff, and supports pollinators.
How we diagnose and fix drainage
1. Site assessment, ideally during or after rain
We want to see where water actually goes, not where it theoretically should. Photos from your phone during a storm are genuinely useful — send them.
2. Find the source and the outlet
Roof volume, neighboring property, driveway runoff or groundwater all get handled differently. Just as important: where the water can legally discharge. We do not solve your problem by creating your neighbor's.
3. Shoot elevations
We use a laser level to confirm actual fall across the property. Eyeballing slope on a flat Northwest Ohio lot is how systems get built backwards.
4. Design and price the system
You get the pipe sizes, depths, discharge location and restoration scope in writing before we start.
5. Install
Utility locates, trenching, bedding stone, pipe at correct pitch, filter fabric, backfill, compaction, then surface restoration.
6. Test and restore
We run water through the system before we close it up and verify flow at the outlet. Then we seed or sod the disturbed ground so the yard does not look like a construction site.
What drainage work costs and why it varies
Drainage pricing is driven by linear footage, depth, and how hard it is to get a machine where the trench needs to go.
- Length and depth of trench
- A twenty-foot downspout extension and a hundred-and-fifty-foot French drain across a back yard are entirely different scopes. Depth matters as much as length.
- Where the water can be discharged
- A daylight outlet at a ditch line is simple. A flat lot with no low point may require a dry well, a pump, or a tie-in to a municipal storm system with permits.
- Soil and obstructions
- Clay trenches cleanly. Old fill with concrete, brick or roots slows everything down. Existing utilities, irrigation lines and invisible fence add hand-digging.
- Surface restoration
- Reseeding a trench line is inexpensive. Restoring an established lawn with sod, or cutting through a driveway or patio and rebuilding it, is not.
- Regrading extent
- Correcting slope near the foundation is a small job. Regrading a half-acre to redirect an entire drainage pattern involves imported fill and machine time.
We will tell you when the cheap fix is the right fix. Plenty of "we need a French drain" calls turn out to be two downspouts and eighty dollars of pipe, and we would rather do that job honestly than sell you a system you do not need.
Why homeowners call us for drainage
We diagnose before we dig
Where the water comes from, where it currently goes and where it can legally be sent are three separate questions, and the answer changes the design completely.
Elevations shot with a laser level
On ground this flat a quarter-inch of fall per foot cannot be judged by eye, and a swale built running the wrong direction is worse than no swale at all.
We tell you when the cheap fix is the right fix
Plenty of calls that start with I need a French drain end as two downspouts and eighty dollars of solid pipe. We would rather do that job honestly than sell a system nobody needs.
We know what fails on this ground
Dry wells in Black Swamp clay, French drains laid without filter fabric, and perforated pipe used for downspout runs are all common here and all avoidable.
Insured, financing available, 46 reviews
Full coverage on every crew, financing on larger corrections, and a review history from neighbours across the region.
Where we provide drainage & grading
Drainage is the service our home counties call us for most, and the old Black Swamp counties call hardest. We correct grade and install drainage across Paulding, Hicksville, Defiance, Payne, Ottawa and Findlay — the last two on the Blanchard River, where a subsurface drain can fill from below instead of draining. Check your county page for what the ground actually does where you live.
