The splash zone is commonly covered in encrusting algae and dark lichens that are tolerant of sea spray. Few other marine organisms can tolerate the almost terrestrial conditions found in the splash zone. Below the splash zone is the high intertidal zone, which is exposed to air for a large part of the day.
Trim installation with paint: $3.50 per linear foot, including materials. Trim installation without paint: $3.25 per linear foot, including materials. Average cost to install trim in a 10x10-foot bedroom: $500 for one window and one door, including labor, materials and paint.
For example, the going rate in our area from a local trim shop is $3 per foot install for 4.25 MDF pre-primed. At that price they will nail, caulk, and fill holes, but no painting. That 12 x 12 room would get them $144. At $60 per hour I would charge $270 for that same room.
