A curtain drain in Ocala is a gravel-filled trench with a perforated pipe set across a slope, uphill of your home, that intercepts surface and shallow groundwater and carries it away before it reaches your foundation or crawlspace. Built with non-woven fabric, washed stone, and real fall, it cuts the water off at the property line instead of mopping it up at the house.
If water runs at your house every time it storms, off a slope, down from a neighbor’s higher lot, or out from behind a retaining wall, the fix is to stop it before it gets there. A curtain drain does exactly that. We cut a trench across the path the water takes, set it on real fall, and send the water around your home instead of through it. The owner, a state-licensed home and building inspector, is on every job.
Water moves downhill and takes the shortest path to the lowest point. If your home sits below a slope, a retaining wall, or a neighbor’s higher lot, your yard is the path. Central Florida is flatter than most places, but it is not flat, and around Ocala plenty of lots have just enough grade to send a sheet of water straight at the low side of the house. Add a layer of clay or hardpan under the sand and the water cannot soak in fast enough, so it runs across the surface and seeps along the top of that hard layer right toward your foundation.
Ocala gets about 52 inches of rain a year, and from June through September it often comes in fast afternoon storms that drop six to eight inches in a month. That is a lot of water arriving all at once from higher ground. You see it in the signs: water sheeting across the yard during a storm, a swale that overflows, ruts and washed-out mulch on the uphill side, a strip that stays soggy on the high side of the house, or a crawlspace that floods only when it rains hard.
Here is the honest part. This usually is not anything you did. The grade was set that way, or the ground above you sends its water across your lot. You deserve to stop the water at the source instead of fighting it at the house every wet season.
Water you do not intercept keeps arriving. Every storm pushes more of it against the foundation, behind the retaining wall, and into the crawlspace, where it softens soil, builds pressure, and feeds mold and wood rot. A wall taking on water from the high side leans a little more each year. A crawlspace that floods every hard rain is a slow leak into the health of the whole house.
There is a second way to lose here: paying for a drain put in the wrong place. A curtain drain only works if it is cut across the water’s path, uphill of what you are protecting, with fabric, the right stone, and real fall. Dropped in the wrong spot or built without those, it silts up or simply misses the water, and the yard floods anyway. Doing it right one time costs far less than digging it up and starting over.
A curtain drain works by interception. Instead of waiting for water to pool at the house and then collecting it, we put the drain between the water and what you are protecting and cut it off on the way down. We read the slope, find the path the water takes, and cut a trench across that path on the high side of the home, the wall, or the crawlspace. Think of it as a horseshoe wrapped around the uphill side. Surface water and the shallow water creeping along the top of the clay layer hit the trench, drop into the stone, enter the perforated pipe, and run off to the side where they can do no harm.
What makes it last is the same craft we put into every drain, and here is why each part matters:

Clean, round stone leaves open space for water to move. We do not use pea gravel that packs tight or crushed lime rock that holds fines and breaks down.
Everything is done to current codes and modern standards, and the owner, a licensed home and building inspector, is on the job doing about half the work himself, because the system is only as good as the installer.
People search this all the time, so here is the straight answer. They are built almost the same, with fabric, stone, and a perforated pipe. The difference is the job they do and where they sit. A curtain drain intercepts moving water, the surface runoff and shallow flow coming down a slope, and it goes uphill of the thing you are protecting to cut that water off before it arrives. A French drain collects water that is already there, the groundwater and standing water pooling in a low spot or against the foundation, and it sits where that water settles. A perimeter drain is a close cousin: it runs around the foundation, near the footing, to relieve water right at the house.
Plenty of Ocala homes need a mix. We will often cut a curtain drain to stop the hillside water, then handle roof water with buried solid PVC underground drainage, and add a French drain only where water still collects. We do not sell you all three by default. We look at your lot, tell you which one actually solves your problem, and build that.
With a curtain drain, placement is everything. A crew that drops a trench in the easy spot instead of across the water’s path will give you a drain that looks fine and still lets the yard flood. We read the slope first, set the line where it actually cuts the water off, and build it with fabric, washed stone, and real fall so it keeps working. It costs a little more on day one, and then you are not paying again to fix water you thought you already handled. Pay once, not twice.
Water sheeting toward the house, a wall taking on water from the high side, a crawlspace that floods in hard rain, or runoff from a neighbor’s higher lot. Call or text and describe it.
We find where the water starts, where it wants to go, and the line that cuts it off: where the trench runs, how deep, how it falls, and where it discharges. If the source is not obvious, our $100 diagnostic gets you a real answer, and it is credited to the job if you hire us.
We cut the trench, line it with fabric, set the perforated pipe on proper fall, surround it with washed stone, backfill, and leave the yard clean. Workmanship is warrantied.
A curtain drain is for the homeowner who keeps taking on water from higher ground and wants it stopped at the source. Many of our clients are established and retiree homeowners across Central Florida who sit below a slope, behind a retaining wall, or downhill of a neighbor whose yard drains onto theirs. If a simple regrade or a swale would do the job, we will tell you that, because the goal is a dry house, not the biggest invoice.
A curtain drain is often one piece of a larger plan. When roof water is the trouble, buried solid PVC underground drainage is the right tool. When water still collects and sits after you cut off the hill, a French drain handles it, and for heavy cases we add catch basins and dry wells. See how it all fits together on our drainage & water mitigation page. We serve Ocala, The Villages, and the surrounding Central Florida communities. See the full service area.
Picture the next hard summer storm. The rain pours down the slope like always, hits the line at the top of your yard, drops into the drain, and runs off around the house. The low side stays firm. The retaining wall is not holding back a pond. The crawlspace stays dry. A day later you walk the yard and there are no ruts, no washed-out mulch, no soggy strip against the foundation. The water still comes down the hill. It just never reaches your house anymore. That is what a curtain drain done right buys you: the high ground handled, and one less thing to worry about every wet season.
A curtain drain is a trench filled with washed stone and a perforated pipe, cut across a slope uphill of what you want to protect. It intercepts surface runoff and shallow groundwater moving downhill, takes it into the pipe, and carries it off to the side by gravity before it reaches your foundation or crawlspace. It stops the water at the source instead of collecting it at the house.
They are built the same way but do different jobs. A curtain drain intercepts moving water coming down a slope and sits uphill of the structure. A French drain collects water that is already pooling or standing and sits where that water settles. Some homes need one, some need both, and we tell you which after we look.
It goes across the path the water takes, on the high side of whatever you are protecting, like a horseshoe around the uphill side of the house or yard. The exact line and depth depend on the slope, the soil, and where the water can safely discharge. Reading that correctly is the most important part of the job.
Yes, that is one of the most common reasons we install them. We set the drain along your property line or just inside it, on the uphill side, to catch the runoff before it crosses your yard and reaches the house. We make sure it discharges to a spot where the water cannot simply circle back.
Many curtain drains run roughly 12 to 24 inches deep, set to catch the shallow water riding on top of the clay or hardpan layer. A drain protecting a foundation or crawlspace may need to go deeper. We set the depth and the fall together so it drains by gravity to its outlet.
Often, yes, when the water is coming from higher ground around the house. A curtain drain on the uphill side intercepts that water before it reaches the crawlspace. If water is also coming from roof runoff or rising groundwater, we may pair it with underground drainage or a French drain, and we will tell you straight after we look.
It depends on the length of the run, how deep it has to go, the soil, and where the water can discharge. We do not post prices because no two lots are the same, and we will not quote you blind. Call or text (352) 440-3310 for a free, all-in estimate.
