<< how do you determine if it is worth it to salage the trim?
Measure the trim. Make a list. Figure how many full size pieces you need (it
comes in 6', 8', 10' sizes). Take your list to a supply source and get prices.
Check your tools. Is your miter saw blade nice and sharp? Do you have some of
the neat trim removal tools that are on the market now?
Do you like the looks of the trim you have now?
Look at your checkbook. Consider your available time.
Bottom line, you will save time and money reusing what you have. It's a
personal choice and you may save some, do some over. Good luck.
