Ceiling Repair – Things to Check Before Calling in a Professional

Ceilings are an often-overlooked component of any room, yet they play a significant role in defining the space and influencing its appeal. Water damage, cracks and sagging are common issues that require repair to keep homes safe and functional.


These issues range from the minor – a drywall or popcorn ceiling that needs touchup – to major repairs and replacements. Repairing them promptly helps avoid costly problems down the road. Check out Ceiling Repair Perth for more information.

A ceiling that’s affected by water damage is not only unsightly but can lead to structural issues, mold or mildew growth and, in serious cases, even collapse. That’s why it’s important to get the issue fixed right away, whether it’s due to a leaking roof or a burst pipe. However, before calling in a professional, there are some things you should do to check that the problem is actually serious enough to warrant an expensive repair job.

Depending on the extent of the leak and the level of water damage, the ceiling may need to be replaced entirely. Some of the most obvious signs that this is necessary include sagging or bubbling in the surface, and visible damp spots. Other warning signs include a musty odor, which usually indicates the presence of mold or mildew, and peeling paint or wallpaper.

Once the source of the leak has been repaired, it’s important to let the area completely dry out. This can be achieved by opening up the ceiling panels and using dehumidifiers, or by removing furniture and other items that might prevent the ceiling from drying properly. It’s also a good idea to replace any insulation that has been soaked.

Once the area has dried thoroughly, it’s possible to paint over the damaged areas if the damage is not too extensive. It’s always best to use products specially formulated for ceilings, and a stain-blocking primer is often recommended. You should also make sure the entire ceiling is dry before painting over any wet patches, as the moisture can cause the paint to peel. In the event of severe damage, a professional might be required to ensure that the new surface is safe and up to recommended safety standards. This will probably involve repairing any structural damage and replacing any drywall or insulation, as well as adding a fresh coat of paint. In some cases, this may also require the installation of a new light fixture.


The good news is that not all cracks on your ceiling are signs of a major structural problem. Most are simply cosmetic and can be repaired easily. The key is to recognize warning signs and work out what’s causing the cracking.

Hairline cracks in your ceiling are almost always caused by temperature or humidity changes. These cause the plaster or drywall to expand and contract, creating unsightly cracks. They are usually not structural problems and can be patched with a putty knife. You can also use a small amount of joint compound or mud to fill these cracks. Make sure to score the crack with a utility knife before applying the mud or joint compound. This will help prevent the mud from sticking to itself or to the wall and creates a stronger repair.

Larger spider web cracks, especially those that show signs of discoloration, are usually a sign of structural movement. This can occur due to a number of things, including foundation settlement or water damage. If you suspect that there is a leak in the ceiling above, it’s important to fix the issue before continuing with any repairs on your ceiling.

If your ceiling cracks are accompanied by sagging, you may have more serious structural issues that need to be addressed. This can be caused by significant water damage, foundation settling, or even the weight of heavy items. If you suspect that your ceiling has sagging, it’s best to consult a professional for advice on how to proceed.

Over time, all homes will experience some cracking. However, the shape, size and location of the crack will determine how serious the issue is and whether it requires immediate attention. Examining the cracking and understanding its causes will give you a better idea of how urgently it needs to be fixed.


If you notice your ceiling is beginning to sag or droop, it isn’t something to ignore. In fact, a sagging ceiling is an indication that there’s serious structural damage and that you should call a professional to come and inspect it.

There are many reasons why a ceiling might begin to sag, including: water damage, leaking roofs, poor building work, or even just the age of the house. The longer you leave a sagging ceiling, the more likely it is to collapse completely, which could seriously injure or kill anyone underneath.

The most common cause of sagging ceilings is water damage. This can occur in a number of ways, but is most commonly caused by a leaking roof, which can lead to the wood in the ceiling joists becoming rotten and weak. If the rotten joists aren’t replaced, the ceiling will eventually sag and collapse.

Another common reason for sagging ceilings is subpar construction, which can include anything from missing load-bearing beams to undersized ceiling supports and joists. These issues can all lead to sagging ceilings and should be remedied as soon as possible to prevent further problems.

It’s also worth considering whether your building was constructed using the right materials. For example, some builders use only 1/2″ drywall for ceilings, which is lightweight and not as sturdy as the more popular 5/8″ option. If this is the case, your ceiling may be more prone to sagging and you should consider replacing it with the thicker version.

In addition, changes in temperature can cause movement and expansion in building structures and materials, including your ceiling. This can also lead to sagging and cracking, so it’s a good idea to have your building regularly inspected by a professional to spot these potential issues early.

One last thing to consider is that a sagging plasterboard ceiling is not usually considered to be a structural defect, but if there’s termite activity in the timber ceiling joists, it’s definitely a case of Caveat Emptor (Buyer Beware). If you’re thinking about buying an older home, have a professional assess the integrity of your ceiling before purchasing it.


Rain, and other forms of precipitation, can bring about many problems in buildings, including unsightly water stains, structural damage, sagging ceilings and mold growth. Unless repaired, these issues can lead to reduced indoor air quality, which can cause health problems for those living in the building.

Mold, which thrives on dampness, sprouts from tiny spores that float in the air and attach to surfaces where moisture accumulates. Once a spore finds a suitable food source, it spreads by sending out roots that penetrate and devour the surface. Mold colonies typically grow in a network of interconnected hyphae, which are threadlike organisms with organelles and cytoplasm flowing from the tips.

Most types of molds are usually not harmful, but some do affect people’s health. For this reason, any type of mold in a building should be cleaned as soon as possible. Molds often grow in porous or absorbent materials such as wallpaper, carpeting, draperies and drywall. If the items are soaked, they should be removed and discarded, and all surfaces that are infested with mold should be thoroughly scrubbed and rinsed.

A professional should be consulted for the cleaning and repair of severe or widespread mold infestations. For a home, this can involve removing the affected drywall, disinfecting all areas of the house and treating all exposed surfaces. A commercial facility may require testing and the development of a remediation plan by a third party.

Depending on the extent of the damage and the type of mold, it may be necessary to replace the entire ceiling. This is particularly true for drywall that has been soaked, which can lose its strength and support structure. If the drywall is not damaged too badly, however, it can be patched and painted.

If the drywall is soaked and damaged, the first step in repairing it is to mix a batch of 20-minute setting joint compound or drywall mud to a peanut butter consistency and apply a thin coat to the ceiling with a taping knife. Once the first coat has dried, mist the ceiling again and apply another thin layer of joint compound.
