Hi everyone - first time poster! Today I started demo on the back side of our house to re-side with hardiplank siding. All went well until the very last piece... Under the sliding glass door, it appears that the siding was finished down to the sill plate like the rest of the house and the concrete step (2-steps) was added later - flush against the siding. There is the top of the bottom course of siding even with the top of the stairs. The sheathing appears to be infested with ants and also possibly water damaged. I checked the back side from the crawl space and there is thankfully no damage visible to the framing (the OSB sheathing is two sheets thick). There is no reasonable way I can think of to get the siding off and replace the bad section of sheathing due to only having about 1/8" gap between the back of the stairway and the siding board. Any ideas that don't involve jackhammering out the stairs?
