#685: Patching Drywall, Adding Air Barriers, and Rotting Walls

When selecting a contractor, prioritize those who can provide proof of comprehensive insurance and bonding, as this often indicates a well-run and responsible business.

Be prepared to pay more for contractors who operate ethically, treat employees well, and offer long-term accountability for their work; cheaper bids may hide unsustainable practices.

For minor drywall damage above a shower unit, consider skim coating with a setting compound like Durabond or installing PVC panels for a quick and durable fix, but address any underlying moisture issues first.

For exposed tongue and groove ceilings in older homes, creating an effective air barrier often requires removing the existing material, installing an air-tight layer (like taped drywall or OSB), and then re-applying the finish.

Poorly graded patios against a house, especially with inadequate weep screed protection, can lead to severe water intrusion; a long-term solution typically involves removing the patio, repairing the wall, and re-grading or installing a drainage system.

Be aware of the significant fire risks associated with lithium-ion batteries in electric vehicles and home energy storage systems, as they can undergo thermal runaway and are extremely difficult to extinguish, often requiring specialized containment methods.
