Not only is this faster but the fixed wood is stronger than the original.

Repairing siding from rot damage.

However the amount of present rot can be deceptive. If your siding has a lot of damage due to pests or rot then that s probably the time to think about replacing it for a more robust siding like this fiber cement lap siding. We tear off the damaged hardboard and replace it with fiber cement siding. The sheathing and framing sometimes need repairs too but that is less common.

Nail it to the sidewall or glue it if nailing isn t possible. If the wood is discolored but the screwdriver test did not detect. Caulk any nailheads that break the paper face. A couple easy solutions that saved me tons of time was to gently pull up on the siding at the studs with a pry bar careful enough not to damage the siding but enough to loosen a nail or two.

If the area of the siding you need to repair is larger than two to four inches the best and most permanent solution is to replace that particular panel of siding. This can be tough since so many times the siding is nailed down. The heads will break the paper face allowing water to soak in and deteriorate the siding. Carefully examine your t1 11 siding for signs of mold wood rot or beyond minor water damage.

Lift the bottom shingle and slip in the kickout flashing. Generally fiber cement sidings last a lot longer than their wooden counterparts. In most cases the original layer of building paper or housewrap at the bottom of the wall was enough to prevent water infiltration and damage beneath the siding. Softwood damaged by wood rot is not salvageable and should be replaced as soon as possible to keep the rot from spreading.

The goal was to get 2 3 inches above the inside of the siding. Seal these joints with a 35 year paintable acrylic caulk.
