How To Repair Rotted Sheathing Behind Brick

Repair or replace sheathing behind brick veneer?

I wanted to go some advice on what to do with existing capsule material that is currently installed backside brick veneer in a 1980's home I'm currently renovating. It's located in Houston, is 2×4 wood frame structure on concrete slab foundation, and the other parts of the house take T1-11 and vinyl siding (which will all be somewhen replaced), simply my questions concern what to do behind the brick for now. Much of the interior has been gutted down to the studs due to issues with mold and pests. In the parts of the house with brick as the exterior, in that location is a layer of 1/viii″ sheet fabric attached to the exterior of the studs, a drainage crenel, and so the brick. There'southward some kind of black flashing coming upward from below, sandwiched between the stud and capsule. The sheet fabric looks like a cross between mineral fiberboard and masonite; information technology has a newspaper-like bankroll that is metallic in color, and afterwards removing the drywall and insulation, a few holes take been uncovered, ranging somewhere between the size of a quarter and that of a grapefruit. These look like they were caused past punctures, possibly during structure, or more often than not past ant infestations, as the holes unremarkably are plant with dirt piles nearby or pouring out of the holes. In a few sections, behind what was once a tiled-shower wall, in that location is a bit of warping of the textile. The warping has caused the canvass to pull away slightly from the studs, and there are a few noticeable gaps where the sail is no longer in direct contact with the wood. There are also one or two areas where the sheets were besides short and do not overlap, so that the woods stud is exposed to the outside. There seem to exist remnants of mold on the surface of the sheet, but non the composite – but I likewise have nonetheless to cut up larger sections to confirm this.

Most of what I've beyond and so far about bug with capsule + brick are flooding related. My moisture issues accept been express to the wet areas of the house, and exercise non seem to be coming direct from the exterior, as far as I know. I'one thousand wondering if the capsule is fine to leave in place, to clean it with detergents, spray with isopropyl alcohol and use a HEPA vac on the remaining spores – the same process I'm using on the studs. If that's a viable option, my question is then how to prepare the holes and the gaps that have opened up. In an article by Allison Bailes ("How I Fixed My Leaky Underinsulated Exterior Wall"), he uses a combination of XPS and spray foam, just I was wondering how that might translate to my specific area and situation. For the outside walls of the firm, I have been planning on using a natural wool insulation, followed past a fiberglass-backed drywall and a lime plaster blanket. The shower areas will receive a tadelakt plaster handling over Kerdi boards/organization. The HVAC systems volition not exist used very frequently, and the priorities are to forestall as much every bit possible whatever future mold growth, while still using more people friendly materials.
