Canexel/Flashing problems

We have water leaking into our basement. Looks like the cause is coming from where the canexel siding meets the brick. The brick covers the bottom layer of the house (first floor) and on top of the bring there is canecel. The problem is there is a 90degree angel between both and the brick is making a ledge for water to sit on. Seems like the canexel edges that are against the brick are lifting up and causing the flashing to slope towards the house instead of away. Is it possible to replace the flashing without having to replace all the canexel? Would caulking the joint between the brick and canexel be enough?

Hi MIndy.

Your assessment is correct. The ledge should really be sloped away from the siding so the water and snow melt will run off not sit and accumulate. You could as you suggested caulk the seam and keep an eye on it. If you do not want to remove the siding, you could have new flashing cap made with a slope and attach it a little higher up the outside of the side, seal the seam and cover with decorative trim that would have to be maintained. This is not the best aesthetic option.

Alex plus 35 year caulking in the color of your siding will take care of the problem, I'd wonder then if all windows were caulked and check to make sure they are.
