French drains
A French drain is a gravel-and-perforated-pipe trench that collects water underground and carries it away from the soggy spot.
Signs you need it
- Grass stays soggy or squishy for days after rain
- Side yard turns to mud between houses
- Water seeps toward the slab or patio edge
- Mosquitoes and moss in the same wet spot
What the job involves
- A local pro walks the yard and finds where water collects
- They pick a route and a safe outlet for the water
- Trench is dug, lined with fabric, filled with pipe and gravel
- Sod or soil is put back over the trench
What affects the cost
- Length and depth of the trench
- Clay soil, roots and sprinkler lines
- Access (hand-dig vs. machine)
- Outlet / tie-in: curb, swale or pump
Estimated cost (Houston): $20–$50/ft, or $1,980–$6,910 total.

Local note: Katy-area clay drains slowly, so water on flat lots can sit for days.

Surface drains & catch basins
Surface drains and catch basins grab standing water at ground level and send it through buried pipe to a safe outlet. Good for ponding on patios and low spots.
Signs you need it
- Puddles on the patio or walkway that never drain
- Low spot in the lawn that ponds after every storm
- Water pooling by the driveway or a fence line
- Dead grass or bare dirt where water stands
What the job involves
- A local pro finds the low points and where water flows
- They set catch basins or grates at those spots
- Buried solid pipe runs to daylight or the street
- Grates are leveled and the lawn is patched
What affects the cost
- Number of basins or grates needed
- Pipe length to the outlet
- Cutting concrete or pavers
- Outlet / tie-in options
Estimated cost (Houston): catch basin about $595–$1,980.

Local note: Many Katy/Fulshear lots are very flat, so a pro has to find enough fall to the outlet.

Downspout drains
Downspout drains tie each downspout into buried pipe so roof water ends up away from the house, not dumped at the foundation.
Signs you need it
- Gutters dump water right next to the foundation
- Splash blocks wash out or mulch floats away
- Erosion trench or wet soil under a downspout
- Extensions in the lawn you keep tripping over
What the job involves
- A local pro checks each downspout and where it can drain
- An adapter connects the downspout to buried pipe
- Pipe is sloped away to a pop-up emitter or outlet
- Trench is backfilled and the lawn restored
What affects the cost
- Number of downspouts and run length
- Going under walks or driveways
- Clay soil and existing landscaping
- Outlet / tie-in to other drains
Estimated cost: $300–$800 per downspout run (estimate).

Local note: Roof water on expansive clay near the slab is a common concern in Katy-area homes.

Yard grading
Regrading reshapes the soil so water naturally runs away from your foundation instead of toward it.
Signs you need it
- Yard slopes toward the house
- Low spots that pond after rain
- Flower beds are higher than the lawn by the slab
- Water runs from a neighbor's yard into yours
What the job involves
- A local pro checks the slope with a level or laser
- They plan where water should flow on the lot
- Soil is moved, added and compacted
- The area is reseeded or sodded
What affects the cost
- Size of the area being graded
- How much soil has to come in or out
- Access for equipment
- Sod or seed afterward
Estimated cost: Ask for a quote
Grading varies too much by lot to give a useful range.
Local note: HOAs in Katy/Fulshear may have rules on lot drainage. Your pro can help check.
