Leak from the roof let water flow down to foundation. A contractor fixed up the rotten joists.
Be sure you've stopped leak that caused rot.
He used 4x4 across several joists and a couple jacks adjustable columns to lift and ease weight on joist ends. Cut out the rotten wood. Lined area with heavy 6 mil plastic. Replaced rotten sill plate and rotten rim (or ring) joist with pressure treated lumber. Add sister joists 4 to 5 ft long with construction glue and 3 inch screws.
You can use the heavy plastic, a hardiplank type board, or maybe the blue foam that is laid under stud walls to seperate the joist from the stone. Just use something waterproof that can take the weight.
One problem I've had is that the repair has bound the sliding door above the repair. As the treated lumber dries and shrinks and settles, the door is loosening. |
