What you'll pay
Yard drainage costs at a glance
In 2026, yard drainage in Surrey ranges from about $500–$1,500 for a single downspout extension, to $3,000–$8,000 for a French drain, to $5,000–$15,000+ for a full regrade.
Surrey clay and 1,500 mm of annual rain mean most yards need at least some drainage work; the fix depends on how much water you're moving and how deep you have to go.

Price ranges
Common drainage fixes & costs
Downspout extension
$500–$1,500 — redirect a single downspout away from the foundation.
French drain (short run)
$3,000–$6,000 — a gravel trench and pipe that carry water off a soggy spot.
Perimeter/curtain drain
$6,000–$8,000 — a drain along the foundation to protect the house.
Catch basin & channel drain
$1,500–$4,000 — catch surface water at patios, driveways and low points.
Full regrade
$5,000–$15,000+ — re-slope the whole yard so water falls away from the house.
Sump pump + tie-in
$2,000–$5,000 — collect and pump groundwater out when gravity alone won't drain.
Cost drivers
Why drainage quotes differ
Two identical-looking yards can quote very differently, because the cost is set by what's under the surface and how the water actually moves.
A yard that just needs a downspout redirected is a small job; a yard that ponds because it's flat on clay and has nowhere to discharge needs real regrading and a run of drain. These are the factors that separate the two.
- Water volume & source
- Lot slope
- Depth & length
