gaps in older wooden trim: caulk or putty?

Circus PeanutApril 16, 2008

hi ho woodworkers,

I have finished stripping all the trim in my 1922 house -- doug fir and lovely, but over the years it has slipped and slid along with the walls, producing several gaps between trim pieces, notably between jambs and header/crown pieces. The gaps range between 1/16" and 1/4" in size. Previous owners filled with white caulk and painted, which is what I've just spent 3 months removing.

The finish painter swears that brown colored caulk is the answer; the finish carpenter swears that a little rubbery wood filler is the answer.

Any standard on this? I fear the caulk, since there's probably no way to get a good match, but fear the putty since it can't possibly be flexible enough for these transitional joints. Your thoughts/experience?

The only really long lasting an workmanlike solution is to remove the trim, plane the back if necessary so it lays flat (Lots of this I see has cupped and pulled away) and renail with a little glue to fix it to the head jamb. I hate the idea of any type of caulk on varnished woodwork. If you don't get the joint tight, all kinds of dust and grit filters in through that seam, esp. in an old house.
I try to plan on taking these pieces off, adjust the miters (mine have mitered corners that became askew) and scrape the paint and caulk from that area, since it is a terrible thing to strip with scrapers, chemicals- you can never get it all.

Argh, Casey, thank you, although I was rather afraid of that answer. Removing and replaning certainly makes sense, even though the doorjambs, for instance, have skewed laterally enough to make a re-match well-nigh impossible without adding more wood to reach the header, or cutting the header down to where it's visibly shorter than its colleagues.

I will muddle along and fend off fillers of all kinds. Many kind thanks!
