Badly installed patio door causing leak


I recently bought a house with many problems. One of those is a leaking patio door (Leaks in the wall causing mold in the basement wall below). The water appears to get in from the exposed horizontal brickwork. I believe this should have been covered with flashing and an aluminum or pvc sill extension when the patio door was installed.

I dont want to install a new patio door. What can I do until then?

Seal it with a good penetrating mortar seal and seal the gap in the threshold and the brick.

If that doesn't do it, you can cover it with coil stock if you want.

Looks like the trim needs caulked too.

Thanks for the tip! Penetrating mortar sealer seems like an easy solution to this problem. I'll apply that and redo the caulking.

Give them time to dry in between.

Siloxane is what we have used previously and seems to work well.

Is this a brick house with a deck attached to it or is that just brick filling in the gap? Why is there brick missing on the right side under the trim?

A picture standing back showing the entire area would help, also another showing the ledger under the deck and how it’s attached to the house.

Brick house with a deck. There is a brick but it's dirty.

+1 to Ron's question.

How is the ledger attached to the home? They are notorious leakers when done incorrectly.

All the sealing and flashing needed to be done under the door, not just some stuff smeared on the outside.

With the deck being that close to the threshold there's always going to be splash back causing an issue.
