What Each System Actually Costs
A breakdown of what you are paying for, where the price comes from, and what cheap quotes typically skip.
French Drain - $2,500 to $6,500
Engineered French drain spec: 18 to 30 inch trench, virgin HDPE perforated pipe wrapped in non-woven filter fabric, #57 washed stone column, Schedule 40 PVC solid pipe for any non-perforated sections, accessible cleanouts every 50 ft, positive slope minimum 1 inch per 10 feet. Cost drivers: run length, depth to hardpan, daylight outfall distance.
Foundation Drain - $4,000 to $12,000
Trenched along the footer, typically 36 to 48 inches deep, tied into the perimeter drain stub or routed to legal discharge. Required when slab edge is saturated or there are settlement cracks. Most expensive variable: distance to outfall and whether hardscape needs to be cut.
Channel Drain - $1,800 to $5,500
NDS Pro Series or Spee-D channel saw-cut into pool deck, lanai edge, garage threshold, or driveway transition. Tied to underground Schedule 40 PVC main. Includes saw-cutting hardscape, setting frame to grade, grout, and outlet routing. Pool decks typically run 12 to 25 LF; full driveway transitions 25 to 60 LF.
Underground Downspout - $200 to $400 each
Standard install: Schedule 40 PVC 4-inch from downspout adapter, buried 6 to 12 inches, routed 8 to 10 feet from foundation, terminated at NDS pop-up emitter. Typical home has 4 to 8 downspouts. Bundling 4 to 8 downspouts in a single project reduces per-unit cost.
Dry Well - $1,500 to $5,200
NDS Flo-Well or comparable, sized to peak rainfall load and infiltration rate. Viable only where soil percolates below hardpan or where you bore through the spodic layer into receiving sand. Will not work on a wet-season-high-water-table lot.
Sump Pump System - $1,500 to $3,500
Submersible pump, 18-gallon basin, check valve, alarm float, and discharge line to street or curb cut. Required on hardpan lots with no gravity outfall. Battery backup adds $400 to $900. Cast-iron pumps last 10 to 15 years; budget plastic pumps fail in 3 to 5.
The 6 Things That Drive Drainage Cost
Run Length and Pipe Footage
Per LF rate covers pipe, stone, fabric, and trenching. A 40 ft French drain costs less per foot than a 200 ft because mobilization is fixed. But the 200 ft total is still 4 to 5x the price.
Depth to Hardpan
Standard trench depth is 18 to 24 inches. If your spodic horizon is at 30 inches and we need to trench through it, depth increases to 36 to 48 inches. That adds machine time, spoil handling, and stone volume. Hardpan trenching adds roughly 30 to 50 percent to the per-LF cost.
Hardscape Demolition
Trenching through a driveway, walkway, or pool deck adds $150 to $300 per linear foot for saw-cutting and concrete repour. A channel drain saw-cut into an existing pool deck is straightforward; a Schedule 40 PVC main routed under a stamped concrete driveway is not.
Distance to Legal Discharge
Every drainage system needs somewhere to go. Daylight outfall to a swale or street curb is cheapest. Tie-in to a CDD stormwater connection or community retention pond adds documentation and discharge box cost. No legal outfall means sump pump plus discharge line, which adds $1,500 to $3,500.
Soil Type and Dewatering
Loose sand digs fast and cheap. Hardpan adds machine time. Wet-season high water table requires dewatering pumps during the install to keep the trench from filling. Wet trenches double or triple labor time per foot.
Restoration and Site Conditions
Sod replacement on the trench line, irrigation reconnect, mulch restoration, and any HOA-required landscape redress. On a Marsh Landing or Sawgrass estate the restoration line item alone can exceed the drainage install on a Mandarin tract home.

Why Cheap Quotes Cost More
The cheap drainage quote in Jacksonville is almost always one of three things: corrugated black pipe in dirt with no fabric, no engineered outfall (the contractor dumps water at your property line), or no Schedule 40 PVC mains. Each of those failure modes shows up within 2 to 5 years. The cost to dig up, dispose, and rebuild is 2 to 3x the original install. The math:
- Cheap install year 0: $1,800
- Failure and re-excavation year 3: $1,200 demo plus $4,500 engineered redo = $5,700
- Engineered install year 0: $4,200
- Year 30 status: still working
Engineered drainage costs more on day one and less by year five. Cheap drainage is the most expensive drainage you can buy.
What Materials We Actually Use
| Material | What It Is | Why It Matters |
|---|---|---|
| Schedule 40 PVC | Rigid-wall pressure-rated pipe, smooth interior | Outlasts the home. Will not warp under roots, will not crush under driveways, will not silt up. |
| Virgin HDPE perforated | Non-recycled high-density polyethylene | UV stable, chemical resistant, holds slot integrity. Not the recycled corrugated black pipe. |
| #57 washed stone | Clean angular gravel, 1/2 to 1 inch | Holds void space for water flow, will not migrate into pipe slots. |
| Non-woven filter fabric | 4 to 6 oz geotextile, wrapped around stone column | Prevents fine sand from migrating into the drainage envelope. Wrapped around stone, not directly on pipe. |
| NDS Pro Series channel drain | Polyolefin channel, ductile iron grates | Rated for vehicle traffic, UV stable, replaceable grates. |
| NDS pop-up emitter | Spring-loaded discharge head | Keeps debris and small animals out of the discharge point. 15 to 25 year service life. |
We do not install recycled corrugated black pipe (the slinky kind). It warps under root pressure, crushes under lawn equipment, and silts up in NE Florida sandy soil within 3 to 7 seasons. It is the single biggest reason cheap drainage fails early.
Frequently Asked Questions
Is drainage in Jacksonville more expensive than the national average?
Modestly, yes. National averages put a full yard drainage install at $4,622. Jacksonville and NE Florida typically run 10 to 20 percent higher because of high water table dewatering, spodic hardpan trenching, and the prevalence of CDD or HOA documentation requirements in newer communities.
Why does my contractor quote $25 per foot and another quotes $60 per foot for the same French drain?
Usually because they are not the same French drain. $25 per foot generally means corrugated black pipe in a shallow trench with dirt backfill and no engineered outfall. $60 per foot generally means engineered: 24 to 36 inch trench, Schedule 40 PVC mains, virgin HDPE perforated, #57 washed stone column, non-woven filter fabric, accessible cleanouts, engineered outfall. Ask each quote to itemize materials and depth.
Do I need a permit for drainage in Jacksonville?
Most residential single-family drainage work in Duval, St. Johns, Clay, and Nassau counties is exempt from formal permitting under SJRWMD residential exemptions. CDDs and HOAs in Nocatee, Fleming Island, Oakleaf, and other planned communities often require their own documentation. We prepare the packet at no charge for any project that needs it.
Can I phase a drainage project to spread cost?
Yes. Common phasing: phase one is downspout extensions and the worst-area French drain, phase two is the secondary French drain or channel drain, phase three is foundation drain or sump pump. We engineer the whole system on day one and phase the install per your budget. Phase pricing typically runs 10 to 15 percent higher than doing it all at once because of repeat mobilization.
Does homeowners insurance cover drainage?
Almost never. Standard HO-3 and HO-5 policies exclude surface water, groundwater, and flooding. Some policies cover sudden plumbing failures inside the home. The exception is post-storm work tied to a covered loss (roof or siding repair) where drainage scope is part of restoration. Always check with your carrier.
What does post-hurricane drainage repair cost?
Highly variable. Clearing a clogged French drain runs $300 to $800. Replacing a crushed corrugated system with engineered Schedule 40 PVC runs $2,500 to $6,000. Full storm-damaged yard regrade plus new conveyance runs $5,000 to $15,000. We prioritize emergency calls during peak hurricane season.
Do gutter and drainage projects get a combined discount?
Yes. When we install seamless gutters, LeafBlaster Pro guards, and underground drainage as a single engineered system, project pricing is typically 8 to 12 percent lower than the same scope sold separately because of shared mobilization, design time, and crew days.
How quickly can you schedule an install?
Typical lead time is 2 to 4 weeks during dry season (December through April) and 4 to 8 weeks during summer storm season (June through October). Emergency post-storm work is prioritized within 48 to 72 hours.
