Drainage contractors
What they do, what it costs, and how to get free quotes.
The short answer
A drainage contractor moves water away from your house and out of low spots in your yard. Call one when water stands for a day or more after rain, runs toward your foundation, or shows up under the house.

Signs you need help with yard drainage
- Puddles that last a day or more after rain.
- Water running toward the slab or under a pier-and-beam house.
- Soggy grass, moss or mud in the same spot every time.
- Downspouts that dump water right next to the house.
What drainage contractors do
- Find where the water comes from and where it should go.
- Put in French drains, catch basins and buried downspout lines.
- Regrade soil so it slopes away from the house.
- Clear or replace clogged drain pipes.
What it costs
A typical job runs about $500–$6,000. Extending downspouts is at the low end. A long French drain or regrading a whole yard is at the high end. These are ballpark prices, not a quote.
How to hire the right one
- Check their license with the state board, and ask for proof of insurance.
- Ask them to call 811 to mark buried lines before digging.
- Get the plan in writing: where the water goes and how deep the pipe runs.
Ask them on the phone
- Where will the water end up?
- Do you use fabric around the gravel so the drain doesn't clog?
- Can I fix part of this with downspouts first?
- What do you warranty, and for how long?

Questions people ask
- Is a French drain worth it?
- Yes, when one spot stays wet and there is a lower place to send the water. If the yard slopes toward the house, regrading may come first.
- Can I fix yard drainage myself?
- Small fixes like downspout extensions, yes. Trenching near the foundation or across a yard is usually better left to a pro.
- When is the best time to see a drainage problem?
- During or right after a heavy rain. Take a video then, so the pro sees what you saw.
