Flashing to protect wood siding from soil/mulch?


I am needing to build up a garden area against my house to create a grade that slopes away from the foundation. The 1950s cedar (?) siding is only about 3" above the mulch as it is now and I need to build the area up above the siding about 2-3". Will aluminum flashing installed over the siding be sufficent to protect it from the contact with the soil/mulch? Is this even the best option for this situation?

That is a perfect way to end up with termites---Soil and mulch should be at least 4 inches below the siding.

So they will chew through the flashing? Is there no barrier that can be put between the soil/mulch and the siding to allow for the needed grade?

The only other option I see is to build a small berm that will keep most of the water away from the foundation. This will lead though to some water pooling against the house with no way to drain away which would not be good.

I understand the problem completely----However any part of a wood structure that is trapped behind soil or concrete as you describe will rot from lack of air circulation or be eaten by bugs---

Raise the foundation or lower the soil add better drainage---those are the solutions that come to mind.

Post a picture if you can----Mike---

Ok here are some pics. Wow the siding looks even worse in pictures Ugh. Anyway, notice the window well. Water pooled up in this general area last Sunday during some very heavy rain and after a while began to run down into the window well and then into the basement. I built the soil up a bit around the well which should help.

The downspout situation you see is a diverter for a rain barrel (removed for this work) but that was unrelated to the flood. No roof rainwater effects this area, it is diverted to the rain barrel or out to the street during a rain event.

It looks like you have enough pitch in the yard to re grade that area so it will flow away all by itself.

I suggest that you drive a stake near the window well and another 15 or 20 feet out and run a level string line---then you can see what you are up against to digging some drainage.

OK I went after it for a rew hours. Just got done. Too dark for pics. And that wasnt soil I was moving around. Picture the most horrible grey clay layered over orange clay with 1-3" rocks mixed throughout. Worst possible crap to have to work with . Hope it works with Irene possibly paying us a visit.

I hope so to---I've see a couple of tropical storms and they are eye openers.

Best of luck----Mike---
