how can we close in a carport if the area floods from rain and a/c condensation?
Obviously without looking at it this is a hard question to answer, but here are some things to think about.
Pipe the condensation away from the area with some pvc tubing. Install new larger gutters (standard gutters are usually 5 1/6” and you can get ones that are 6” and large downspout 3”x4”) and more downspouts that are run away from the area with more PVC piping under ground. That should fix the water problem and then you can use the carport for what ever you like...but the water problem needs to be addressed first.
If the gutters are over flowing you should also check and make sure they are installed and pitched correctly so that the water is flowing through the gutters properly. If you are unsure how to do that you should consider having your local NARI (National Association of the Remodeling Industry http://www.nari.org/) contractor come out and check these items.
