Discoloured ceiling cracks usually mean water damage. If you run a finger over them, they may even be damp to touch. These cracks vary in severity depending on the cause, so it's important to find out where the water is coming from and fix that problem before addressing the cracks. Potentially, depending on the cause.
Large, deep cracks are a serious concern. In case you have large, deep cracks alongside sagging ceilings, this means major structural damage that needs to be dealt with immediately as the ceiling may collapse.
Cracks in Your Ceiling
If you notice cracks in your ceiling, it's a good indication that there is water damage. These cracks can be caused by a leaky roof, a broken pipe, or even condensation.
Typically, plaster ceiling cracks have two causes: house settling and temperature or moisture fluctuations in an attic, which result in the expansion or contraction of framing members. Solution: Homeowners can fill these commonly occurring hairline cracks with new plaster and repaint the ceiling.
If you discover ceiling cracks that look thick in size, this can be a sign of structural damage. These could be a sign of subsidence or structural damage that could get worse over time.
Here's how to know if a crack is structural: One of the easiest 'tells' for structural damage cracks is that they grow over time. A thin, non-structural crack can quickly become a structural foundation crack if it gets wider after several weeks or months.
Cracks that run across the ceiling and down the wall.
Any crack that runs all the way across a ceiling and then down a wall is almost certainly the result of structural damage. Contact a foundation professional right away.
The culprit, in this case, is improper taping. Basically, contractors install drywall in sheets and stick it together with drywall mud. Then, tape is put on over the mud before you paint. If that seam is between the drywall and, in this case, an improperly sealed ceiling, the tape will start to lift and form a crack.
Peeling, bubbling or flaking paint. Water rings, typically a light brown color. Musty smells. Water stains, which often present as dark, yellow or rust-colored.
Watermarks or Brown “Rusty” Stains– Oftentimes one of the most common signs of ceiling or roof water damage is watermarks or brown “rusty” stains on the walls, ceilings and/or attic. It can be a sign of a previous or current leak, so you should always have them checked out if they appear within your home.
It's important to assess the nature of your ceiling cracks before you embark on any repair work. The good news is that in most cases, it's relatively simple to patch up and restore the surface to its former glory. We've asked the experts for advice on how to fix ceiling cracks.
If the crack is deep, you may need to patch it with a patching agent. However, if the problem is only a hairline crack, the ceiling paint can do the job of covering it.
A professional painter will be able to patch your ceiling easily. But remember that it is your job to make sure no moisture is coming from the attic. You will have to hire another contractor to fix any moisture issues you may have again.
Water-damaged ceilings are high-priority issues that lead to rot, mold and a weaker house frame. Leaks must be fixed, and water-damaged ceilings repaired, as soon as possible.
Water Damage
A big question homeowners often ask is “does wet drywall always need to be replaced?” and the answer is almost always yes.
The necessary period to dry out the ceiling will vary based on how wet the ceiling got. It can take a minimum of two weeks but sometimes up to four weeks. Ensure you address the leak's cause to ensure you are solving the problem rather than going in an endless circle.
Repair Type
For example, fixing a hairline crack in plaster costs between $100 and $300, while fixing a crack in drywall costs between $100 and $500. Fixing a hole in the ceiling can be as much as $600. Repairing an unsightly seam in a ceiling has a price range of $150 to $500.
The secret to making sure that the crack doesn't reappear is really just down to using jointing tape. This method works every time and it doesn't matter if you're plastering over it, using a filler like we did here or even if you're installing plasterboards (where you have to tape the join to ensure it doesn't crack).
The reason you hear it especially at night time is because the roof space cools down at night while the sun is down, so the creaking is the wood adjusting to the new air temperatures. The wood contracts while the space gets cooler.
Hairline ceiling cracks are tiny, thin fissures that almost look like someone painted hair to the drywall. Hairline cracks are typically caused by plaster or drywall mud issues, not the drywall itself.
In the absence of any external damage, a POP false ceiling can easily last for 15-20 years. One doesn't need to worry about longevity in the case of POP.
Water damage is one of the most common causes for plasterboard ceiling replacement. If water has caused the ceiling to blister or crack badly, or when it has started to sag, or when it has started to lose its strength and become wet in certain areas, then this signals that it's time for a replacement.
