Bought a 45 year old split level 1.5 years ago. It was not lived in for a year before we purchased it. We painted all rooms with latex paint.
We had French door installed in lower level of house. 3 months later
50% of drywall seams are showing in whole house. Not just the downstairs area.Walls are swirled plaster finish over drywall or whatever it was they used in those days for a plaster veneer. House is platform framed with wood.
Contractor used jacks to support roof during french door install but suspect he used moist wood and that stud shranks. Entire house has 8' ceilings. Ceiling in front of french door is 1/4 to 3/4" lower than 8 feet. He used jack and 1 king stud with engineered wood header for door. Door is operational and not sticking.
Could settling of the the roof above the 6' area were the french door was installed have affected the drywall seams in entire house?
I am thinking that top plates are pressing down more on the drywall than before causing the seams to show. Though seams also show in ceiling in upper level of house away from construction activity.
If the French door is the likely problem, what is best way to resolve this problem?
Will reinstalling the framing for the door with dry and proper sized studs solve the problem?
Or, once the drywall seams have bulged as they have will they remain that way? Drywall is not like a rubber band. If the roof had resettled after door was installed, putting in 1/4 to 1/2 longer studs in the 6 foot wall area (by reinstalling the door) might not achieve anything.
Not worried about any structural problem.
If I have to live with this, and reinstalling door will not resolve this, then what is best solution to resolve this issue which I believe is only cosmetic?
Since there is a swirl plaster pattern on walls, I cannot simply sand the seams and patch and paint as necessary. It would leave long noticeable lines that break the swirl pattern.
I prefer not to remove drywall in all affected areas. Should the plaster walls be replastered to hide seams. Can they be skim coated with joint compound?
Appreciate any thoughts on this. Tried to get a consultant on this, but local architects/engineers don't respond. Scary, what if I want to add an addtion to house in future? Would architect or engineer come out then?
