Foundation Drainage in Columbus, Ohio

Transit & Flow Group corrects water problems right at the foundation line across Columbus and Central Ohio, where negative grading, a failing footer drain, or a poorly placed downspout sends water directly against the wall instead of away from it. Foundation drainage is narrower in scope than general yard drainage; it’s specifically about the few feet of ground closest to your house. Describe what’s happening at your foundation in the Estimate Builder for a preliminary online estimate, or book a foundation drainage assessment.

Is this the right service for you?

Foundation-line water problems look different from general yard puddling. This is the service for you if:

• The ground slopes toward your house instead of away from it, right along the foundation wall. Called negative grading, and one of the single most common causes of basement seepage in Central Ohio.
• A window well fills with water during rain, or stays damp for days after.
• Mulch beds against the foundation stay soaked, holding moisture right against the wall longer than the rest of the yard.
• A downspout empties within a few feet of the foundation, with no extension carrying the water further out.
• You see efflorescence (white mineral staining) or damp patches on the foundation wall, especially at the base.
• A perimeter drain tile system that’s decades old and may have silted up or collapsed, no longer moving water away from the footer the way it once did.
• You already know this is different from your yard being generally wet, because the problem is specifically hugging the house, not spread across the lawn.

If your wet spot is closer to the middle of the yard or a side lot rather than right against the wall, our yard drainage page covers that broader scope; foundation drainage and yard drainage often overlap, and either page can route you to the right one after a quick look at your specific situation.

How pricing works

Foundation drainage is priced as a range, driven by how much of the foundation needs attention and what’s actually causing the problem. The logic:

• Grading correction near the foundation sits at the lower end, when the fix is reshaping the soil slope for a section of wall.
• Exterior perimeter drain work (a footer-level French drain run along part or all of the foundation) sits higher, since it involves deeper excavation closer to the house.
• Window well drainage and downspout rerouting are priced individually and often bundled with grading work when several small issues are found together.
• What changes the price: how much of the foundation perimeter is affected, excavation depth, existing landscaping or hardscape in the way, and whether an existing failed drain tile needs replacing rather than a fresh line added.

Enter your project details and photos in the Estimate Builder for a preliminary online estimate. Final scope and price subject to verification on site. Angi’s 2025 data puts exterior foundation drain (footer drain) installation at a general market range of roughly $10 to $25 per linear foot, often landing in the $4,500 to $12,000 range for a full perimeter on an average home; that figure is general market context, not a Transit & Flow Group quote, and your scope may only need part of the perimeter addressed.

What’s included

• An on-site assessment measuring grade slope specifically along the foundation wall
• Identification of the water’s path into that section of foundation
• A written recommendation: grading correction, exterior perimeter drain, window well drain, downspout rerouting, or a combination
• Utility locate coordination before excavation near the foundation
• Compacted, properly sloped backfill so the corrected grade doesn’t settle back to negative within a season
• Photos of the work at the foundation line for your records
• All workmanship is backed by a 1-year labor warranty on labor, parts, and equipment covered per manufacturer terms.

What’s not included

• Interior waterproofing, crack injection, or structural foundation repair
• Full-yard drainage work beyond the foundation perimeter (see Yard Drainage)
• Sump pump installation or replacement for groundwater pressure issues
• Foundation wall repair for cracking, bowing, or settlement, quoted as a separate structural scope

Why Central Ohio foundations need this attention

Central Ohio’s clay soil barely absorbs water, and nowhere does that matter more than the few feet immediately around your foundation, which is why grading and drainage fixes right at the wall are such a routine part of homeownership here. Builders grade a new home’s foundation correctly at construction, but clay settles unevenly over the years, and what was a gentle slope away from the house in year one can quietly become flat, or even reversed, by year fifteen. Freeze-thaw winters accelerate that settling every single season.

Heavy spring rain is when foundation-line problems show up most clearly, because saturated clay has nowhere left to send water except sideways, toward the path of least resistance, which is often the loose backfill soil right against your foundation wall from when the house was built. That backfill zone drains differently than undisturbed soil further out, which is part of why foundation-specific drainage work is its own service rather than just an extension of general yard grading.

Our process

1. Describe the problem online. Where along the foundation the water shows up, and photos, go into the Estimate Builder for a preliminary online estimate.
2. Foundation drainage assessment. We measure grade slope at the wall, check window wells and downspout placement, and look for signs of drain tile failure. Final scope and price subject to verification here.
3. Written recommendation. A plain explanation of what’s causing water at your foundation and the specific fix, priced.
4. Utility locates, then work begins. Grading correction, drain installation, or downspout rerouting, in that priority order when several apply.
5. Verification. We confirm the corrected grade actually slopes away from the house before calling the job done.

Our crews are Bonded & Insured Professionals. Services completed by appropriately qualified professionals where required.
