Stucco to replace T111
I bought a 1950s repo last December and have been mainly focused on the interior up until now. I finally have enough done inside that I can start thinking about the exterior. The previous owner enclosed the carport and used T111 wood siding. The rest of the house is stucco. The carport enclosure addition was done without a permit, so it goes without saying that the quality of work done could be better. The majority of the T111 needs to be replaced. It was not sealed well, and there is no flashing or protection along the bottom edges. When it rains the siding absorbs some moisture through the bottom. Fortunately I live in Southern California and it only rains a few times a year.
I would like to make the exterior look more cohesive and stucco the carport addition. I don't know if it is possible to stucco over the T111, or if that is even a good idea. I am not really concerned about water damage behind the siding, we did a lot of gutting on the interior and there were no signs that water had damaged anything other than the exterior siding.
Also, when the previous owner poured some concrete around the exterior of this addition, they poured it directly against the siding. I am planning to rip out that concrete and redo it (its cracking and uneven). I am sure that when I do that some of the siding is going to come off with the concrete!
I'd like to know the most cost effective way of redoing the exterior of this portion of the house. If it is going to be significantly more expensive to replace the siding with stucco, I don't know if I would do it. Although I know that the aesthetic value of having the exterior all one material may be worth the extra cost.
