Moisture content of baseboards
I am a DIYer fixing up a home we are plan on living at for 20 years or more. I am putting in new baseboard through out the house. I do not want to use stock molding and have decided to make my own by routing some simple, clean angles.
I am pretty skilled with a saw and my angles are good, however I'm concerned about installing trim in the summertime as it is fairly humid here in Wisconsin. What can I do to ensure that my joints will stay tight for years to come? Most of my walls are broken up with registers/cold air returns so I don't really have any long runs that will require joining multiple boards. I'm really just concerned about butting up to the door jams.
For all the door trim I used poplar and finished them last winter. Now poplar has gotten quite a bit more expensive. Can I use aspen instead? Will aspen route well? The trim will all be painted when finished.
Thanks for any help
