How to avoid water being trapped at the corner of my house?

You need to change the slope of the landscaping in this area. It needs to be graded so the water drains away from your house. My husband did this in one of our houses by hand, with a shovel. It was a lot of work, but solved the problem.

Good suggestion from Ann, you might also look at the downspouts and make sure they are taking the water away from the foundation.

We built up the corner of our home with landscaping as Anne suggested. We actually built it up about 8 inches and it worked like a charm.

I forgot to mention that this is a 4’x4’ planter area in the corner. The rest is a concrete patio.

I had the same problem when I moved into my old house. I 1)add extensions to the downspouts to move the water further out to the driveway, 2) my handyman tilted the gutter itself downward a few degrees to the downspout so the water ( that can be very heavy here in the PNW) drained faster to the downspout and prevented it overflowing over the edge, and 3) I had the whole upper edge of the gutter caulked along the soffit to again prevent it backflowing down the wall. If the gutter downspout flows over the sideway along side the building, you may have to dig under the sidewalk to put your gutter extensison underground....

Adding drains to the area should solve your problem. They will need to run along the the entire foundation and away from the house quite a distance, depending on how much water you have.

I'd try adding small pebbles to see if that helps.

Hi Sandy,

Did you get a home inspection before you purchased the property?

What did the inspector's report say regarding the poor drainage and moss build up in the corner?

Not sure where you are and the building codes in your area, but your house is lacking perimeter drain tile.

I would get a local building contractor in to give you a estimate. Quite a big job but should be done...

In many locations, codes generally apply only to new construction builds.

It could be that when this house was first built, either ;

1/ a code specifying that particular drain tiles were installed was not in existence or

2/ there was no inspection to verify that they were/not installed according to code or

3/there was no enforcement imposed on the builder for not installing properly according to any existing code

Irregardless of what the scenario was, the new home owner has little recourse to correct the situation other than to install a new system.

If the hired company considers themselves as professional, they should want to complete the job to meet with new-build codes presently in effect.

Because it is uneven and all of the water flows into that corner, I would suggest pouring concrete there and making it level so water won't flow there. I agree that it can cause hidden water damage that you don't want!

You need to have the concrete resurfaced with the correct slope away from your home.
