When it comes to pre-existing shutters, our standard procedure is to paint them while they are still attached to the house. We do this since most shutters in Colorado Springs are not fitted with the capacity to open and close.
There is a high chance of damaging pre-existing shutters while removing them. Therefore, we recommend leaving the shutters in place when painting your exterior. If you want to replace your shutters, you may pull down the old ones, paint them, and then install the new ones.
