You get those as the seasons come and go, wood expands and contracts.
How the drywall was installed can make a big difference. Several years ago had a similar situation, every year the drywall would crack, I tried a flex crack filler and it worked short term, we moved to new house so cant swear to longevity!
looks like a joint where tape was originally applied.
That would be an odd place for tape. It could be a corner bead crack but it looks like it could be higher than the top edge of the corner bead.
The odds are a house built 44 yrs ago would be drywall and not plaster ..... and by then all new plaster jobs were a veneer plaster [thin coat of plaster over blue board drywall]
Maybe the OP means the house was built in '44. Could be plaster. If the corner bead is expanded wing corner the width would be about right but probably X wing was not used so still hard to explain.
Hello from Texas. I am new to forum. I recently purchased a 50s home. I loved the architecture of home. However after moving in and winter start I figured we don't have insulation in the exterior walls. So my daughter's room is the first I am working on since it is small in size. To my surprise I found bottom 1/3rd of wall is cinder blocks. I assume this was done because house is on a slope and back side of room is 1/3 is below ground. However now I am not sure how can I insulate this bottom part. Top is regular framing that I can easily insulate.
building room in basement- Don't like the idea of drop ceiling or sheet rock for ceiling. Saw some pics of people using wainscoting or beadboard with pine for trim. I love the look- but it looks like most of these were installed over an existing sheet rock ceiling. I am concerned it will not look as good over the floor joists there now. Not sure if it will lay as flat or look wavy. Anyone have any experience or thought on this?
