Ceiling damage can occur in houses after you own them for awhile. Here are the most common reasons:
- Studs and joists may shift a bit over the years and cause cracks. For large amounts of damage, you may need to take out the drywall and add some more studs. For a single crack, you can simply use some dry wall compound on it. Fixing a crack in your ceiling in this way may take anywhere from a few minutes to hours.
- Water damage. In bathrooms and other areas with moisture, you could have problems with the ceiling cracking and/or sagging. You can attach the old drywall to the seam and stud with some screws. This works well if the dry wall is quite new.
- Popped out nails and screws. This may happen from time to time as the studs shrink over a few months or years. You will need to cut away a bit of drywall from around that nail. Just tap it back in and cover it with dry wall compound and let it dry for a day. Then you can sand it down and repaint it.
These problems with ceiling damage can be a small or large job, depending on the particular circumstances. Most often, fixing cracks in the ceiling are best handled by professionals, especially when there are large amounts of damage.
