Drainage Contractor or Foundation Contractor — Who Do You Actually Call First in Jacksonville?
If you're seeing water around your home — soggy yard, damp crawlspace, efflorescence on stucco, or visible cracks — you're staring at a decision that has a 10x cost spread depending on whether you call the right trade first. This page is the honest decision framework, written by an NDS Certified drainage contractor who also coordinates with the major foundation repair firms in Northeast Florida (Sunshine Foundation Repair, Metro Foundation Solutions, Alpha Foundations, Groundworks). The answer is not "always foundation" and it's not "always drainage." It's a diagnosis.
The 30-second answer
Call a drainage contractor first if: water symptoms are outside the foundation (soggy yard, mulch washouts, damp crawlspace, efflorescence on exterior stucco) and you have no visible structural damage. Drainage stops the water source — typically $2,500 to $20,000.
Call a foundation contractor first if: you have visible cracks in walls or slab, doors that stick or won't close, floors that are out of level, or active settlement. Foundation repair fixes structural damage that's already happened — typically $15,000 to $50,000+.
Call both if: you have active interior water intrusion AND structural symptoms. Stop the water inside (foundation/waterproofing), then engineer drainage outside so it doesn't return.
The Decision Framework: 5 Symptom Types and Who Fixes Each
| What you're seeing | Call first | Why | Typical cost |
|---|---|---|---|
| Soggy yard, mulch washouts, standing water within 5 ft of foundation, no interior symptoms | Drainage contractor | Pure exterior water-routing problem. No structural damage yet. Drainage stops the trajectory before damage starts. | $2,500–$10,000 |
| Damp or musty crawlspace, persistent humidity, no cracking | Drainage contractor first; interior waterproofing only if symptoms persist after drainage | ~80% of crawlspace moisture in NE FL is exterior in origin. Stop the water from reaching the foundation; the crawlspace usually dries on its own. | $3,000–$8,000 drainage; $4,000–$12,000 added waterproofing if needed |
| Efflorescence (white chalky deposits) on interior block or exterior stucco; no cracking | Drainage contractor | Visible proof of active water movement through the foundation material. Foundation isn't damaged yet — but the trajectory is set. Drainage is the cheaper insurance. | $5,000–$12,000 |
| Visible cracks in walls or slab, doors sticking, floors out of level, active settlement | Foundation contractor (Sunshine, Metro, Alpha, Groundworks). Drainage after. | Structural problem requires structural diagnosis and repair. Drainage second to prevent recurrence after foundation work. | $15,000–$50,000+ foundation; $5,000–$15,000 follow-up drainage |
| Active water intrusion — water on the floor, pooling in basement or crawl | Both — sequentially. Interior remediation/sump first (stop the water now), drainage second (engineer the prevention) | Emergency requires immediate interior response. Long-term solution is exterior water-source elimination. | $3,000–$10,000 immediate; $5,000–$15,000 drainage rebuild |
The Decision Tree: 4 Questions to Ask Yourself
1. Do you see any structural damage?
Visible cracks in walls or slab. Doors sticking or out of plumb. Floors visibly out of level. Sheetrock cracking at corners.
Yes → Foundation contractor first. Get structural diagnosis. Drainage is part of the repair plan, but second.
No → Continue to question 2.
2. Do you have water actively inside the home right now?
Water on the floor. Pooling in basement, crawlspace, or garage. Active leaks during rain.
Yes → Emergency interior response first (sump, vacuum, dehumidifier, sometimes waterproofing contractor). Then drainage contractor to engineer the long-term fix.
No → Continue to question 3.
3. Are your symptoms moisture-related but not structural?
Damp crawlspace. Musty smell. Efflorescence on block or stucco. Stucco staining. Mulch washouts. Soggy yard against the wall.
Yes → Drainage contractor first. ~80% of moisture symptoms in NE FL have an exterior water source that drainage can eliminate. Interior waterproofing is a backstop if drainage doesn't fully resolve.
No → Continue to question 4.
4. Is the symptom outside the home only?
Standing water in yard. Soggy lawn. Erosion. Pooling at downspouts. Driveway puddles.
Yes → Drainage contractor. No foundation involvement needed. This is what drainage was designed to fix.
Why the Order Matters: A 10x Cost Spread
The reason this decision matters more than most homeowners realize is that calling the wrong trade first usually means paying for both, in the wrong order. Three common patterns:
Pattern 1: Call foundation when you needed drainage
Homeowner sees efflorescence on a stucco wall, calls a foundation specialist. The foundation company sells $25K of underpinning the home didn't need yet. Six months later, water symptoms return because the source was never addressed. Now they pay $8K more for drainage. Total: $33K for what should have been $5K-$10K of drainage in year one.
Pattern 2: Call drainage when you needed foundation
Homeowner sees standing water and a sticky door. Calls drainage, gets the yard drained, ignores the door. Two years later, the door is unusable and floors are visibly out of level. Now they pay $35K for foundation repair that would have been $20K if caught at the sticky-door stage. The drainage work is still useful — but the foundation damage compounded while it sat.
Pattern 3: Call interior waterproofing when you needed exterior drainage
Homeowner with damp crawlspace gets sold $12K of encapsulation, dehumidifier, and vapor barrier. The crawlspace stays drier for a year. Then a heavy storm year saturates the perimeter soil and the moisture returns — because the water source outside was never fixed. They now pay $8K of drainage on top of the $12K of interior work. Drainage first would have been $5K-$8K total.
Why we recommend drainage first in 80% of NE Florida moisture cases
Northeast Florida's combination of sandy topsoil, hardpan clay subsoil, high water table during the wet season, and heavy summer storm volume means most foundation moisture has an exterior source. Roof runoff dumped at the wall. Yard graded the wrong direction. Downspouts that end inches from the foundation. Footings without perimeter drainage.
Fix the exterior, and the interior usually dries on its own. Interior remediation has a place — encapsulation, vapor barriers, sump pumps, dehumidifiers all do useful work in the right scope — but they're treating symptoms. Drainage treats the cause.

Coordination: When the Job Needs Both Trades
Mixed-scope work (drainage + foundation, or drainage + waterproofing) needs to be sequenced correctly. The wrong order means you pay for one trade to undo the other's work. The right order, documented as part of every Gutter Pro quote where coordination is needed:
- Foundation repair first if there's active structural damage — underpinning, slab jacking, crack injection. The foundation has to be stabilized before any work that disturbs soil around it.
- Interior remediation second if water has already gotten inside — vapor barrier, encapsulation, sump pit. This stops the immediate moisture problem.
- Drainage third — but engineered to address the original water source so the foundation and interior repairs don't repeat. This is what we do.
For pure drainage scopes (no foundation involvement), step 3 is the whole job. For pure foundation scopes (active settlement, no current water source), step 1 is the whole job. Most cases sit somewhere in between, and the on-site assessment determines the sequence.
The Trades in Northeast Florida — Who Does What
| Trade | What they install | When to call them | Common NE FL firms |
|---|---|---|---|
| Drainage contractor | French drains, channel drains, catch basins, dry wells, underground PVC routing, foundation perimeter drains, sump pump systems, regrading coordination | Exterior water symptoms, damp crawlspace, efflorescence, mulch washouts, soggy yard, foundation moisture without structural damage | Gutter Pro (NDS Certified) |
| Foundation contractor | Helical piers, push piers, slab jacking, crack injection, underpinning, structural repair | Visible cracks, doors sticking, floors out of level, active settlement, structural assessment needed | Sunshine Foundation Repair, Metro Foundation Solutions, Alpha Foundations, Groundworks |
| Interior waterproofing | Vapor barriers, crawlspace encapsulation, interior sump pits, dehumidification, interior wall sealants | Active interior moisture after drainage is in place; basement/crawl encapsulation; mold remediation companion work | Various; often part of foundation firm or standalone waterproofing |
| Gutter contractor | Seamless gutters, downspouts, gutter guards. Often the upstream cause of drainage problems. | Always — most drainage problems start with undersized or poorly placed gutters | Gutter Pro (also drainage) |
How a Diagnosis Walk Works
- Free on-site assessment. Albert walks the property, evaluates exterior water sources, checks crawlspace or slab perimeter for moisture symptoms, inspects gutter and downspout system, identifies whether symptoms are drainage-fixable or structural.
- Honest diagnosis. If it's a drainage scope, we quote it. If it's structural, we tell you which foundation specialist to call and why. If it's mixed, we lay out the sequence.
- Written documentation. Diagnosis, recommended scope, and (if coordination is needed) a handoff plan documented so multiple trades work in the right order.
- No high-pressure pitch. Most homeowners get one walk-through and a clear answer. Drainage scopes typically quote in 2 business days.
Drainage vs Foundation FAQ
Should I call a drainage contractor or a foundation contractor first?
If you have visible structural damage (cracks, sticky doors, settlement), call a foundation contractor first. If you have moisture symptoms without structural damage (damp crawlspace, efflorescence, soggy yard, mulch washouts), call a drainage contractor first. About 80% of moisture symptoms in Northeast Florida have an exterior water source that drainage can eliminate.
What's the cost difference between drainage and foundation repair?
Drainage typically runs $2,500 to $20,000 depending on scope. Foundation repair typically runs $15,000 to $50,000+. Calling the wrong trade first usually means paying for both — drainage fixed earlier prevents most foundation work that drainage would have addressed.
How do I know if my problem is structural or just drainage?
Structural signs: cracks (especially diagonal cracks at door and window corners), sticky doors, floors visibly out of level, sheetrock cracking, slab settlement. Moisture signs (without structure): damp crawlspace, efflorescence on block or stucco, soggy yard, mulch washouts, persistent humidity. If both, both trades are needed in sequence.
Will fixing drainage prevent future foundation problems?
It dramatically reduces the risk. Most NE Florida foundation problems are caused by repeated soil saturation against footings — water-source elimination prevents that. It does not reverse damage that's already occurred. Catch the problem at the moisture stage (year 1) and drainage is the whole fix. Wait until year 5 and you need both.
Why do some contractors push interior waterproofing first?
Because they sell interior waterproofing. Vapor barriers, encapsulation, and interior sumps are their product. Those tools have a real place, but they treat symptoms. If the water source outside is still there, the symptom comes back. Drainage first is usually the cheaper, longer-lasting fix in NE Florida's exterior-driven moisture climate.
Do you do foundation repair?
No. We're drainage specialists. When a job needs foundation work, we refer to one of the specialty firms in the area (Sunshine Foundation Repair, Metro Foundation Solutions, Alpha Foundations, Groundworks) and document the handoff so the trades work in sequence. We don't take work we're not certified for.
Can drainage work be done while foundation repair is in progress?
Usually no — they need to be sequenced. Foundation work disturbs the soil around the perimeter, which means any drainage installed before foundation work has to be re-done after. Foundation first, drainage second.
What happens if I do nothing?
The unaddressed-water timeline is consistent: Year 0–1 cost to fix is $500–$7,500 (drainage only). Year 3 same root cause now requires $5,000–$12,000 (drainage + early remediation). Year 5+ structural damage starts, $25,000–$50,000+ (foundation + waterproofing + drainage). Year 7+ active failure, $50,000+ plus possible insurance and mortgage complications. None of this is inevitable — drainage installed early stops the trajectory.
Do you charge for the diagnosis?
No. On-site assessment is free. If it's a drainage scope we want, we quote it. If it's structural, we tell you which foundation specialist to call. Either way you leave with a clear answer.
How fast can you assess?
Typically within 48 hours of your call. Active intrusion or post-storm emergencies get prioritized to same-day or next-day where possible.
