Moisture that builds up inside a building or in framed cavities can eventually lead to materials deteriorating and rotting. This is very bad for structural integrity!

Where does rot commonly happen?

• At mud sills and rim joists that get constantly wet
• Door and window sills made of wood
• Poorly ventilated attics where moisture builds up on rafters and roof sheathing / planks
• Anywhere where plumbing fixtures leak for an extended time.
