![]() ![]() Since plaster is extremely rigid, the slightest movement can cause a gap. In older homes with plaster ceilings, movement and moisture may create cracks. Solution: If the gaps are wider than 1/8-inch, it’s a good idea to consult a reputable home builder, since you may have a structural problem. These superficial hairline cracks can usually be re-taped-but, if the house continues to settle, the cracks are likely to reappear in the same spots. ![]() Homes naturally settle as they age, which can create crevices in the walls and ceilings typically above doors and windows as well as in corners. Ceiling cracks accompanied by wall cracks could be the result of the house settling. This cosmetic ceiling repair won’t stop the trusses (and the ceiling drywall) from lifting with moisture and temperature changes, but the dark color of the molding will disguise the appearance of the crack, while also adding a decorative touch to the room. The molding should be attached only to the framing members in the wall-not to the ceiling joists. If a homeowner doesn’t care to repair the issue, they can camouflage the crack by installing dark-stained crown molding around the top of the room. It’s best to hire a professional for this project. Solution:The only way to permanently fix the issue is removing the nails or screws that secure the edge of the drywall panels to the trusses, and reattaching them to clips or blocks installed on the top of the interior wall plates. This common mistake often occurs if a handyman attaches drywall panels to the trusses near the edge of a non-load bearing wall. When the roof truss pulls upward, it may lift the ceiling drywall along with it, creating a crack between the wall and the ceiling. Roof trusses are designed to move slightly as their wood members expand and contract with attic temperature and moisture fluctuations. Truss uplift can cause a horizontal crack between an interior wall and the ceiling. You could also remove the existing texture by sanding-a messier prospect-and apply new drywall compound to the ceiling. Solution: To conceal the blemishes, try applying a thin layer of drywall compound over the existing texture. ![]() If it was applied too thickly, you may notice tiny cracks that run in all directions because the compound shrinks as it dries. Thinned drywall compound is often used to create a textured ceiling. Photo: Tiny spiderweb cracks may suggest thick application of drywall compound. If the drywall has swollen or softened, it’s no longer viable the damaged section must be replaced before re-taping and re-texturing. Note: Drywall will resist some moisture, but long-term leaks can result in water damage, which requires replacement of the damaged drywall. If you have a textured ceiling, use an aerosol texture product (found in home improvement stores) to cover the newly re-taped joint so it blends into the ceiling’s existing texture. Solution: To undo the damage done to the ceiling, scrape off the loose tape and re-tape the joint, either with a drywall repair kit or paper tape and joint compound. Before you can repair the ceiling, determine the cause of the leak and fix it. Sometimes, water from an overhead leak can trickle between the ceiling’s drywall panels, causing the joint tape to loosen, creating the appearance of a crack, and leaving unsightly yellow or brown stains. A discolored crack indicates a moisture problem. You can also minimize the appearance of the crack by applying a small amount of thin drywall compound under the loose tape and re-adhering it to the drywall. Solution: Homeowners can choose to ignore this superficial problem, since it isn’t a structural or safety hazard. As a result, you may notice a straight “crack” along the edge of loosened tape. If an insufficient amount of drywall mud was used during the taping process, the paper tape won’t adhere well to the joint. Causes of Ceiling Cracks-and How to Fix Them A fine straight ceiling crack could be the result of a poorly taped joint. Here’s how to deal with cracks in the ceiling, whether they appear in the bedroom, kitchen, basement, or other room of the house. Examining the shape, size, and location of the crevice can give insight into possible causes and solutions. ![]() But some cracks-especially those wider than 1/8-inch-may signal structural issues. A: Over time, virtually all homes will develop cracks that are cosmetic in nature and not indicative of a larger problem. ![]()
