Every property is different, so no honest pro can put a firm number on drainage sight-unseen. But we can tell you exactly what drives the cost — and roughly where common jobs land — so you can budget with your eyes open.
What determines the price
- Length and depth of the run. A short drain to dry one soggy corner is quick; a long system protecting a foundation means more trench, more pipe, more labor.
- How hard the digging is. Granite Bay's rocky decomposed-granite ground and clay can slow excavation, and roots, hardscape, or utilities in the path add time.
- Where the water can discharge. A close, easy outlet keeps it simple. If water has to travel a long way to reach a safe discharge point, that's more pipe and trench.
- The type of solution. A downspout reroute or a single catch basin is on the affordable end; a full French drain system or regrading a yard costs more.
- Restoration. Putting lawn, beds, or hardscape back the way we found them is part of a proper job and factors into the price.
Rough buckets, cheapest first
- Small fixes — rerouting downspouts underground, adding a single catch basin, a minor regrade of a low spot. The most common and most affordable.
- Mid-range — a French drain for a soggy lawn area, a network of a few catch basins tied together, or grading correction around part of the house.
- Bigger jobs — foundation/footing drains, whole-property water management, or extensive regrading. These cost the most because of the excavation and materials involved — but they protect the most expensive parts of your home.
The honest promise: whatever bucket you're in, you get the exact price up front, before any digging starts — and estimates are free. No mystery numbers, no surprise add-ons.
How to avoid overpaying
Two things save you money. First, get it diagnosed properly. A lot of "I need a full drainage system" problems turn out to be a downspout dumping at the house plus one low spot — a fraction of the cost of the big job someone else quoted. Second, don't wait. Water against a foundation or a slow leak into a crawlspace gets more expensive the longer it sits — see protecting your foundation. Catching it early is almost always cheaper than the repair it prevents.
