Little areas can be fixed utilizing high-performance wood bonding resins, whereas bigger areas of structural damage (often the window sill) may need "splicing"-- where the rotten area is cut out and changed with a new piece of skilled hardwood.

To make sure longevity, the timber is primed, undercoated, and finished with top quality micro-porous paint. This type of paint enables the wood to "breathe," avoiding moisture from ending up being trapped under the surface area and triggering future rot.
