Inspected a failure. Apparently the wall had leaked so the mold company went into the attic and removed all the Tyvek paper from the inside. Just ripped it all out.
Then a different contractor came and removed the siding and tried to restore the torn paper.
It did not end well.
Unless there was no sheathing.. I have seen it before, where they installed siding directly to studs.
Morning, Bryce. Hope you are well.
Was the unintended event, moisture intrusion and posable microbial proliferation in the exterior wall assembly, from a call you received for a quote, or just a general information inquiry post?
I am trying to envision removing WRB installed on exterior wall assembly surfaces from inside an attic. I could only come up with gable end or dormer side walls as the walls. Removal of WRB, a fool’s errand, likely to be costly for all involved.
Removing and replacing WRB, Weather Restrictive Barrier, Tyvek is a brand of, The WRB is secured to wall studs or sheathing, and requires overlaps.
When repairing exterior assembly leaks in siding, the first step removing the exterior envelope siding. Trying to cut corners is a fool’s errand like putting a 10 pound silami in a 5 pound paper bag and expecting it to be under the principles of alchemical, the medieval tradition of Hermes Trismegistus, (Thrice-Greatest Hermes), a mythical figure believed to have invented a magical seal to make glass vessels airtight.
Hopefully the WRB was atop the sheathing.
Is that apparently in good condition gable in a mostly windward or leeward or sheltered from winds? If not, its just a matter of time.
WRB is applied on top of sheathing, not behind it. WRB, Weather Resistive Barrier is applied and secured on top of sheathing. The idea, to create a continuous, water-resistant layer that protects the structural wood sheathing from moisture that gets behind the exterior siding in the forms of condensate to bulkwater.
I repaired similar jobs due to leaks. I ripped every off the gable end and side walls down to the bottom/sole plate, while removing unneeded fasteners. I repaired rotted or damaged sheathing and studs, and stiffened the wall assembly. Corners metal flashed.
Thanks for sharing, Bryce.
No sheathing.
McMansion style: a big house but not built to last. The siding was that pressboard stuff.
Thanks, Bryce.
Sidewall siding panels. Got it.
Missing metal wind braces straps or 2x4s installed diagonally between exterior wall studs to provide lateral stability to prevent walls from moving or racking.
Big homes get buffeted by winds.
Looks like skip sheathing was sheathed with OSB.
From Google.
A McMansion is a large, ostentatious, and often poorly built suburban house that prioritizes size and superficial luxury over architectural integrity and quality.
