Water that collects next to a house is behind much of the rot we repair. Good drainage does not have to mean big excavation. These low-impact steps keep water moving away from your home.
Start with the roof
Every downspout should carry water several feet away from the foundation. Extensions, splash blocks or a connection to a drain line make a big difference.
Grade away from the house
Soil should slope away from the foundation. Bark and soil piled against siding hold water against the wall and rot the bottom plate.
Keep clearance at the siding
Leave several inches between soil or mulch and the bottom of siding and trim, so wood can dry after rain.
Low-impact options
| Option | What it does | Best for |
|---|---|---|
| Rain garden | Lets water soak into planted soil | Yards with space and decent soil |
| Dry creek bed | Carries water across the yard | Directing downspout runoff |
| Rain barrel | Captures roof water for gardens | Reducing runoff volume |
| Permeable pavers | Lets water through paths and patios | Replacing solid surfaces |
Under decks and porches
Make sure water does not pond under decks. Gravel, landscape fabric and a slight slope away from the house help framing stay dry.
When to call a pro
If water already reaches the siding, sill plate or crawlspace, fix any rot first, then correct the drainage so it does not return.
