I have a two year home. A few weeks ago I noticed 2 straight lines bulging from corner of the ceiling. Please see attached image. Any idea what it is, and how to repair it or how much would it cost to repair it?

Your help is much appreciated,

Thank you

I'm just going to guess here but I'd say your partition walls are to the truss and they most likely didn't use drywall clips ... that is caused by shifting of your home. The truss pulls and if the drywall is screwed in without using clips that happens to your corners.

Contact the builder that is an issue for him to fix ... should be at no cost to u.

Big gap behind the taping or not enough mud. Usually we pre-fill all the gaps with 90 before tapping.

I would agree with that comment about not enough mud if it had happened way before now.

Applying tape without enough mud or because of gaps in the drywall should show as soon as you apply paint.

Separation of tape from the ceilings and walls is usually caused by movement of the truss while the house sets...

If this is a one story home or if it's a 2 sorry and the area that needs repair is around and form of trusses I'm almost positive that's the reason.

That cost should be covered by the builder.

While in repair please look to see if clips were used. If not the builder should be held responsible for future tape separation which will continue to happen for up to 7-10 years.

Thank you very much for your replies. I forwarded it to the builder, and I thick they will look into it during the one year inspection (house 2 years, but I moved less than a year ago). Is it normal for a house to set or settle like that? Its strange that the puffed area does not show any signs of cracking. Also I believe that there is no attic over the bedroom (I will climb up there next week), and the bedroom is built on top of a car garage. Also maybe the roof shifting could have been caused by strong winds. I might just hire an inspector again at the one year and check that stuff more thoroughly. When the inspector checked the house for the 30 day inspection, he didn't notice anything.

I also noticed that a lot of the corners in the house, in most rooms have long vertical cracks, probably because they never used any tape.

From years of experience doing drywall and repairs cracking in corners usually higher up towards the ceiling is usually caused by the same thing... when the truss move and the drywall wasn't installed proper you'll see cracking and tapes lifting . . An inspector is a good idea so your able to show the builder ... .

If they do find that the board was installed incorrectly request it to be all removed don't allow a fix in certain areas because it will continue to happen until it's completely fixed

I took a closer look with the ladder, and noticed a few cracks along the bulging line. I added a pic.

Also I have a another question to anyone who has any drywall experience. On my 30 day inspection I noticed that most conrners of the house are cracked, just like in the second pic attached. They came to fix the issue, but I thin they just painted over the cracks. Is it common for the corners of the house to crack due to settling and drying?

One other possibility could be that they built during the boom(like in Calgary) and sometimes when this happens the wood they get for construction is still green, because they can't keep up with demand, then the house is finished and the wood dries and it can twist, making bulging out in some places and cracking along seems in other places, if this is the case simply repairing the cracks can be enough, assuming the wood is finished drying.

Builder fixed the issue a while ago. It was the tape coming off the wall
