Two published frames, named apart and never blended
| Frame | What it prices | 2026 band |
|---|---|---|
| Frame A | trench or channel drain installation, per linear foot | $30-$150 |
| Frame A | driveway trench or channel drain, average | $400-$2,400 |
| Frame B | trench drain, channel-style, per project | $1,500-$4,000 |
| Frame B | trench or channel driveway drainage system, average per linear foot | $70 |
Neither frame folds into the other: Frame A reads the project per linear foot, with a driveway average beside it; Frame B reads it per project, with a system band beside it. The material layer prices on the material guide; the driveway layer on the driveway guide.
Frame A lines, as reported
| Frame A line, as published | Reading | 2026 band |
|---|---|---|
| Trench or channel drain installation, in HomeGuide drainage-system data | per linear foot, by grate and channel material | $30-$150 |
| Driveway trench or channel drain, in the same data | average, per driveway run | $400-$2,400 |
| Channel width named inside the driveway line | 4 in to 8 in | inside the driveway band |
Frame A is one printed reading in one HomeGuide cost page: a per-linear-foot band turning on grate and channel material -- plastic, metal, or concrete as printed -- and a driveway average turning on size, channel width, and grate material, with fiberglass named among the driveway grate materials. By-width bands price apart on the driveway guide.
Frame B lines, as reported
| Frame B line, as published | Reading | 2026 band |
|---|---|---|
| Trench drain, in Angi's trench-vs-French comparison | per linear foot | $30-$150 |
| French drain, in the same comparison, printed beside it | per linear foot | $10-$50 |
| Trench drain, channel-style drain for surface water, in Angi's basement-drain data | per project | $1,500-$4,000 |
| Trench or channel driveway drainage system, in HomeAdvisor (Angi) data | average, per linear foot | $70 |
| Drainage system installations, in Angi trenching data | per system | $2,111-$6,775 |
Frame B prints the same project three ways, each on its own line: a comparison rate per linear foot, against the French drain rate beside it; a per-project band for a channel-style drain, inside a basement-drain table; and a system band for drainage installations as a class. Its one driveway-specific rate is an average, not a band: $70 per linear foot.
Quoted apart from french drains and driveway builds
Contractors quote surface channel drains apart from french drains and driveway rebuilds: per linear foot and per driveway run, for garage aprons, pool decks, and patios as printed placements. The buyer's question is the cost of the run across the width already in place.
The neighbours, differentiated head-on
The nearest borders, named plainly: a french drain guide prices a buried pipe, a paver guide prices a driveway build -- this cluster prices only the surface channel build. The french drain page prices a french drain as a subsurface pipe project; the paver driveway page prices a paver driveway as a driveway build, a channel named only as a component.

Frequently asked questions
How much does trench drain installation cost in Orange County?
Two frames, never blended. Frame A: $30 to $150 per linear foot, driveway average $400 to $2,400. Frame B: $1,500 to $4,000 per project, drainage systems at $2,111 to $6,775.
What does a driveway trench drain cost, as reported?
Frame A prints a driveway trench or channel drain at $400 to $2,400 on average, by driveway width: $400 to $1,200 for a 1-car width, $800 to $2,400 for a 2-car width, and $700 to $3,000 for a 1-side run. Frame B prints an average rate of $70 per linear foot.
What is the per-project line either frame prints, as reported?
Frame B prints it: a trench drain, a channel-style drain for surface water, at $1,500 to $4,000 per project in Angi's basement-drain data. Frame A prints no per-project band; its readings are per foot and per run.
Is a trench drain build the same purchase as a french drain or a paver driveway?
No, head-on: a french drain guide prices a buried pipe, and a paver guide prices a driveway build. A trench drain build is a surface channel priced per linear foot, per driveway run, and per project; this hub prices that build.
Why do the two frames print such different bands for the same project?
Frame A reads the build per linear foot, turning on grate and channel material, with a driveway average beside it; Frame B reads it per project, inside wider drainage tables. Each stays on its own frame.
