How we fix it
Our approach
Map the roof water
We check where each downspout lands and which ones are feeding water to the foundation.
Bury solid pipe
Each line is trenched and piped below the lawn so there is nothing to trip over or mow around.
Discharge away from the house
Lines end where the yard slopes away, at a point that suits your lot.
Restore the lawn
Trenches are backfilled and the sod goes back where it came from.
Common questions
Downspout Extensions FAQ
How far should a downspout discharge from the house?
Far enough that the water keeps going away from the foundation. The right distance depends on your slope and soil, which is why we walk the yard first.
Is this really enough to stop a leak?
For a corner that only leaks in heavy rain, it often is. It is also the least invasive place to start.
Can you tie several downspouts together?
Often, yes. We size the pipe for the roof area it has to carry.
