2. Stripping and Repair
Old paint layers-- which frequently contain lead and conceal rot-- are removed away. Specialists utilize specialist techniques like the "Window Care System" or resin repairs to combine soft wood instead of replacing the entire piece. If a section is too damaged, they will perform a "splice repair work" using matching lumber types such as Accoya or slow-grown redwood.
