Step 1
Remove the interior or exterior wall sheathing to expose the wall studs and plates. Remove any insulation between the wall studs. This exposes the studs for work.
Step 2
Scrap away any rotted lumber from the exposed studs. Make any repairs necessary to prevent moisture from reaching the studs. Dry wall studs are less likely to rot than dry lumber.
Step 3
Cut new lumber to the length of the rotted studs. Matching the exact length of the studs is vital. If the new stud is too long, it will push the top plate up and can affect the roof position. If the new stud is too short, it will not support the plate and roof. Use the same type lumber as the rotted studs.
Step 4
Fasten the new lumber to the existing studs. This process is known as sistering studs. Use 2 1/2-inch wood screws to fasten the new stud to the most solid portions of the old studs. If the old stud is completely rotten and has no solid sections, add new studs to both sides.
Step 5
Replace wall insulation and wall sheathing to restore the wall to regular use.
