What our French drain installation includes
Every French drain installation Naples FL project includes the core work below. Add-ons like sump pumps, dry wells, and battery backups are priced separately. We tell you upfront what your yard needs and what it does not.
- Site evaluation and planWe walk the property, shoot grades with a transit level, and mark the trench route. You get a written scope with pipe size, trench depth, and discharge location. This plan is yours to keep.
- Trenching and gradingWe cut a 12 to 18 inch trench, grade it to a 1 percent slope, and protect landscaping. We hand-dig near foundations and utilities. The trench is ready for fabric and pipe the same day.
- Perforated pipe and gravelWe install 4 inch perforated drain pipe wrapped in filter fabric and surrounded by washed #57 gravel. The fabric keeps sand out, and the gravel creates a void that stores water during heavy rain.
- Discharge connectionWe connect the perforated run to solid PVC discharge pipe and route it to a pop-up emitter, dry well, or storm drain. If gravity flow is not possible, we install a sump basin and pump.
- Testing and cleanupWe flood-test the system with a hose and show you the water exiting the discharge point. Then we backfill, compact, restore sod or seed, and haul away excess dirt. You get a walkthrough and a maintenance sheet.

What French drain installation Naples FL actually involves
French drain installation Naples FL is a buried drainage system that collects groundwater through perforated drain pipe set in gravel and carries it away from your foundation to a safe discharge point. We trench 12 to 18 inches deep, line the trench with filter fabric, lay the pipe at a precise 1 percent slope, and backfill with washed gravel. The system ties into a PVC discharge pipe that exits at a pop-up emitter or dry well, so water never sits against your slab.
Naples sits on a high water table, and summer storms dump 2 to 3 inches in an afternoon. If your yard holds water for more than 24 hours after rain, you are one step from slab moisture and cracked stucco. A French drain installation service Naples FL gives that water somewhere to go. We see it most in Old Naples and Coquina Sands, where older lots were graded before modern drainage standards. Call us before the next storm season.
Water finds the low spot. We build the path that moves it away.
Our French drain installation process
We handle every step from layout to final grade check. Most residential systems take one to two days. Here is exactly what happens when you hire us.
Site evaluation
We walk your property, check the slope with a transit level, and locate the high water table. We mark the trench route, discharge point, and any irrigation or utility lines. You get a written scope and a fixed price before we dig. This visit takes 45 to 60 minutes.
Trenching and grading
Our crew cuts a 12 to 18 inch deep trench along the marked route using a trencher and hand tools near structures. We grade the trench bottom to a 1 percent slope so water flows by gravity. We protect existing landscaping with plywood boards and hand-dig within 24 inches of your foundation.
Pipe and gravel install
We lay filter fabric, set 4 inch perforated drain pipe, and surround it with washed #57 gravel. The fabric keeps fine sand from clogging the pipe. We connect the perforated run to solid PVC discharge pipe and install a check valve if the discharge ties into a sump basin.
Discharge and testing
We route the discharge line to a pop-up emitter, dry well, or storm drain, maintaining the required slope. Then we flood-test the system with a hose to confirm flow. You watch the water exit the discharge point before we backfill. Any slow spot gets corrected on the spot.
Backfill and cleanup
We backfill with gravel and native soil, compact in lifts, and restore the grade. Sod or seed goes down over the trench. We haul away excess dirt and wash down hardscape. You get a walkthrough, a maintenance sheet, and our number for questions.
Tools and methods we use
Transit level
We shoot grades to confirm the 1 percent slope before trenching. This prevents flat spots where water stalls and sediment collects.
Walk-behind trencher
Cuts a clean 6 to 8 inch wide trench through Naples sugar sand and shell hash. We hand-dig within 24 inches of foundations and utilities.
4 inch perforated drain pipe
The core of the French drain. We use rigid PVC or HDPE pipe with holes that collect groundwater along the entire run.
Filter fabric
Wraps the gravel and pipe to keep fine sand from clogging the system. Naples soil is sandy, so fabric is not optional.
Washed #57 gravel
Creates a void around the pipe that stores water during heavy rain and lets it percolate into the soil.
Zoeller and Liberty Pumps sump pumps
When gravity discharge is not possible, we install submersible pumps from these brands to lift water to the discharge point.
Check valve and float switch
The check valve stops backflow into the basin. The float switch triggers the pump at the right water level. We test both before we leave.
1 percent slope grading
We grade every trench to a 1 percent fall, which is about 1 inch per 8 feet. This is the minimum slope that keeps water moving without eroding the pipe. We verify with a transit level before backfilling.
When Naples homeowners call us
A low corner of the yard holds water for days after summer storms in Golden Gate.
We install a 60-foot French drain along the low side, grade the trench to a 1 percent slope, and discharge to a pop-up emitter at the curb. The pipe is wrapped in filter fabric and set in washed gravel. The corner drains within hours of rain. The homeowner can mow and use the yard without rubber boots.
Water seeps into the garage of a 1970s ranch in East Naples after every heavy rain.
We trench along the garage slab, install perforated pipe and gravel, and tie it into a new sump basin with a submersible Zoeller pump. The discharge line runs to a dry well in the side yard. The garage stays dry through a 3-inch storm. The pump cycles only during extended rain, not constantly.
A homeowner in Pelican Bay is building an addition and needs drainage for the new roofline.
We design a French drain that ties into the existing stormwater system, install 80 feet of perforated pipe, and connect two downspouts to the discharge line. We pull the right-of-way permit for the connection. The addition passes final inspection. The yard around the new slab stays dry, and the homeowner avoids a grading violation.
A property manager in North Naples has a commercial lot with a soggy parking area.
We install a French drain with a channel drain across the low spot, route the water to a dry well, and add a sump pump with a float switch alarm. The system handles runoff from 5,000 square feet of pavement. The parking area drains after storms, reducing liability and keeping tenants happy. The alarm alerts staff if the pump ever fails.
How French drain installation works in Naples
Naples drainage is different from most of Florida. The water table sits 18 to 36 inches below grade in the rainy season, so a shallow trench can hit groundwater. We design French drains with that in mind, often adding a sump basin and pump where gravity flow is not reliable. Summer storms drop 2 to 3 inches in an afternoon, and the sandy soil saturates fast. We size the pipe and gravel void to handle that surge. Winter is dry, which is the best time to install: the trench stays open, and the system is ready before June. We serve homeowners from Port Royal to Golden Gate, and we know the soil in each neighborhood. If you need a French drain installation in Naples, Florida, we can usually schedule a site evaluation within the week.
- Old NaplesOlder lots with mature landscaping and tight setbacks. We hand-dig near roots and foundations, and route discharge to the alley or street where permitted.
- Pelican BayHOA rules require neat restoration and sometimes approval for discharge points. We provide a written scope you can submit to the architectural review board.
- Golden GateMany homes sit on slab with shallow swales. The water table is high, so we often pair a French drain with a sump pump to lift water to the street.
- Port RoyalLarge estate lots near the water. We design systems that handle both groundwater and roof runoff, with discharge to a dry well or the canal where allowed.
- High water table in rainy seasonGravity discharge may not work when the water table rises above the pipe. We add a sump basin and pump to lift water out, or design a shallow system that stays above the table.
- Sugar sand and shell hash soilSand migrates into the pipe without filter fabric. Shell hash drains well but can shift. We use fabric and washed gravel to stabilize the trench and keep the system flowing.
From problem to finished result.
Soggy Old Naples side yard
BeforeA 1,200 square foot side yard held 2 inches of water for three days after every summer storm. The turf was dead, mosquitoes were thick, and the homeowner could not use the patio. The slab edge showed efflorescence.
AfterWe installed a 90-foot French drain with a dry well discharge. The yard now drains within 6 hours of a 2-inch rain. The homeowner replaced the dead turf with St. Augustine sod and uses the patio every evening.
Flush the line with a hose each spring and check the dry well for sediment. We offer an annual inspection that includes a flow test and discharge check.
Garage seepage in East Naples
BeforeA 1970s ranch home had water seeping under the garage wall after every heavy rain. The slab was damp, and boxes stored on the floor were ruined. The homeowner was considering a costly foundation repair.
AfterWe trenched along the garage slab, installed 70 feet of perforated pipe and gravel, and tied it into a sump basin with a Zoeller submersible pump. The garage stayed dry through a 3-inch storm two weeks later.
Test the pump monthly by pouring water into the basin. Replace the battery in the backup system every two years. We inspect the float switch and check valve annually.
Commercial lot flooding in North Naples
BeforeA 5,000 square foot parking area flooded after storms, creating a liability and keeping customers away. The existing swale was undersized and clogged with sediment.
AfterWe installed a channel drain and a 120-foot French drain that routes water to a dry well. The lot now drains within 2 hours of a 2-inch rain. The property manager added a sump pump alarm to alert staff if the system ever backs up.
Clean the channel drain grates monthly and inspect the dry well each quarter. We offer a commercial maintenance plan that includes pump testing and line flushing.
Drainage problems we solve in Naples
Standing water, foundation moisture, and mosquito swarms all trace back to poor drainage. Here are the most common problems we fix with a French drain installation for foundation protection Naples Florida.
Yard floods after every storm
We install a French drain sized to your square footage and soil type. The perforated pipe collects surface and subsurface water and routes it to a discharge point. Most yards drain within 24 hours of a storm. Standing water kills turf, breeds mosquitoes, and makes your yard unusable for days. It also saturates the soil against your foundation, raising hydrostatic pressure.
Water seeps into the garage or slab
We trench along the foundation, install perforated pipe and gravel, and route water away from the slab. If gravity discharge is not possible, we add a sump basin and pump to lift the water out. Moisture against the slab causes efflorescence, stucco cracks, and interior dampness. Left alone, it can undermine the foundation and lead to costly repairs.
Sump pit fills with water constantly
We inspect the French drain inlet and discharge line. Often the drain is clogged or undersized. We clean or replace the line, verify the slope, and install a properly sized pump with a check valve. A pump that runs constantly wears out fast. The float switch fails, the pump overheats, and you are left with a flooded crawl space during the next storm.
Mosquitoes swarm the backyard
A French drain eliminates the puddles mosquitoes need. We route water to a dry well or discharge point that stays dry between storms. Most homeowners notice fewer mosquitoes within two weeks. Standing water breeds mosquitoes in 7 to 10 days. This makes evenings outside unbearable and can lead to health department complaints in some neighborhoods.
A dry yard, a protected foundation, and no more standing water.
Protects your foundation
Water pooling within 10 feet of your slab finds every crack. A French drain installation in Naples, Florida intercepts groundwater before it reaches the foundation, reducing hydrostatic pressure that causes efflorescence, stucco cracks, and interior dampness. We slope the pipe at 1 percent so water keeps moving, never stalls.
Ends standing water
If your yard holds a puddle for 48 hours after a storm, you have a drainage problem. Our French drain setup Naples removes surface and subsurface water, turning a swampy back lawn into usable space. Most systems clear a 1,500 square foot area within 24 hours of installation.
Stops mosquito breeding
Standing water breeds mosquitoes in 7 to 10 days. A French drain eliminates the puddles they need. For Naples yards near the Gordon River and low-lying areas in East Naples, this is the difference between enjoying your patio and hiding indoors at dusk.
Adds usable yard space
A soggy side yard is wasted space. Once we install French drain Naples, that area drains within hours of rain. Homeowners in Pelican Bay and Park Shore use the reclaimed space for vegetable beds, play sets, and dog runs. The system pays for itself in usable square footage.
French drain installation cost in Naples
French drain installation in Naples costs $1,800 to $4,500 for most residential projects in 2026. The price depends on trench length, discharge method, and whether a pump is needed. A simple 50-foot run with a pop-up emitter is at the low end. A 150-foot perimeter system with a dry well and sump pump is at the high end. We give you a fixed written price after the site evaluation, so you know the cost before we dig. No hidden fees, no change orders for normal soil.
What your estimate is based on
- Trench lengthLonger runs need more pipe, gravel, and labor. A 50-foot drain takes one day. A 150-foot perimeter system takes two days. We measure your yard and quote by the linear foot.
- Discharge methodA pop-up emitter at the curb is the least expensive. A dry well costs more because we dig and fill a larger hole. Connecting to a storm drain requires a permit and adds cost.
- Pump requirementIf gravity discharge is not possible, we install a sump basin and pump. A submersible pump, basin, check valve, and wiring add $800 to $1,500 to the project.
- Soil and accessSugar sand is easy to trench. Shell hash or roots slow the crew. Tight side yards or fenced lots require hand-digging, which adds labor. We assess access during the site evaluation.
- Permits and restorationRight-of-way permits and sod restoration add cost. We include permit fees in the quote when required. Sod replacement is priced per square foot if you want us to restore the lawn.
$1,800 - $4,500 depending on scope A French drain protects your foundation, reclaims your yard, and reduces mosquito breeding. Compared to foundation repair, which can run $10,000 or more, the cost of drainage is small. We give you a fixed price and a written scope so you can compare quotes.

What to know about French drains
A French drain moves water by gravity, but it needs the right slope and a place to discharge. Here is what matters most.
Slope matters
The pipe must fall at least 1 percent, about 1 inch per 8 feet. A flat trench holds water and clogs with sediment. We check the grade with a transit level before backfilling.
Fabric stops sand
Naples soil is sandy. Without filter fabric, fine sand migrates into the gravel and pipe, clogging the system within two years. We wrap the gravel and pipe in fabric to keep it flowing.
Discharge point
The drain needs somewhere to send water. A pop-up emitter, dry well, or storm drain all work if they are lower than the trench. When they are not, we install a sump pump to lift the water.

Reviews from Naples homeowners
Most residential French drain installations in Naples run $1,800 to $4,500 in 2026, depending on trench length, discharge method, and whether a pump is needed. A simple 50-foot run with a pop-up emitter sits at the low end. A 150-foot perimeter system with a dry well and sump basin lands at the high end. We give you a fixed written price after the site evaluation.
If water stands in your yard for more than 24 hours after rain, or you see damp patches on the slab edge, you need one. Naples has a high water table and sugar sand that saturates fast. Other signs: mosquito swarms, moss growing on the lawn, and stucco cracks near the base. A French drain setup for yard drainage Naples FL solves all of these.
A French drain setup in Naples Florida uses a gravel-filled trench with perforated pipe to collect groundwater and route it to a discharge point. Water enters the pipe through the holes, flows by gravity along a 1 percent slope, and exits at a pop-up emitter or dry well. We add filter fabric to keep sand out and a check valve if the line ties into a sump basin.
A typical residential French drain installation in Naples takes one to two days. A short 50-foot run is a one-day job. A full perimeter system with a dry well and pump connection runs two days. We schedule the work, show up when we say we will, and leave the yard graded and clean. Rain delays are rare but we reschedule fast.
