I recently bought my first house and I noticed some rot happening beside our garage door. It appears that when the cement driveway was poured, they got too close to the siding and now water is wicking up into the wood. I figure I can cut back the siding and replace it but how do I stop this from happening again?
Replace the bottom few inches with Hardie Plank
If you do end up replacing just a bottom portion, be sure you use some Z-flashing so that rain water can't get behind the seam. As mentioned, use something that won't rot. I also recommend using Hardie Sierra 8 to replace entire sections, I have it on some portions of my house along with T1-11 and they compliment one another as long as they are not side by side.
