Ceiling Repair – When to Hire a Professional

Ceiling Repairs Perth can take a beating over time and may suffer from damage such as cracks, sagging, water stains and discoloration. Some of these issues require professional attention to prevent further damage and costly problems.

While it’s possible to handle small cracks in a ceiling with spackling, larger repairs should be left to professionals. Hiring a professional ensures that the problem is properly addressed and won’t reappear months later.

Damp or wet patches on ceilings are not only unsightly but also a sign of more serious issues, such as water damage and mould or mildew growth. These problems can lead to the need for extensive and costly repairs.

If you notice a damp patch on the ceiling, you should act quickly to address it. This may involve repairing a leaking pipe, fixing a leaky roof, or improving ventilation in the home to prevent excess condensation. It is important to treat the underlying problem as well as the damp patch, or else the problem will return and may become worse.

A wet patch on the ceiling is a sure sign that there is moisture in the air, and this could be due to either a plumbing leak or excess condensation in your home. A damp spot that has a brown colour to it is often linked to a leaking pipe, while a wet patch with a white colour is usually caused by condensation forming in the room above.

In addition to a wet patch, damp or wet areas on the ceiling can also be accompanied by other signs of moisture problems, such as musty odours and a general feeling of humidity in the home. Damp and wet areas on the ceiling are an ideal environment for the growth of mould and mildew, which can release spores into the air that cause respiratory problems for people with asthma or other respiratory conditions.

Moisture problems in the home can be prevented by regular maintenance checks on the plumbing and roof, improving ventilation and increasing insulation to reduce condensation levels. Using dehumidifiers can also help. If you notice that a damp or wet area on the ceiling is not being treated, it is important to seek advice from a professional as soon as possible to prevent long-term damage and health issues. Addressing the issue promptly will help prevent ceiling rot and structural damage to your property. It will also help to protect the health and safety of your family or tenants by preventing the spread of mould and mildew spores throughout the building.


If you have ceiling cracks, you may need to hire a professional to assess whether they’re serious or not. Some cracks are merely a result of normal house settlement, while others indicate serious structural damage that needs addressing. In some cases, the cause is a leak that requires the attention of a plumber before the cracked ceiling can be fixed.

Hairline cracks that appear at joints between sheets of plasterboard are fairly common and are usually a result of poorly filled and taped joint areas when the building was originally constructed. Cracks in this type of area tend to open and close with seasonal changes in temperature and humidity.

Wide horizontal cracks across the ceiling are generally a sign of serious structural damage and require immediate professional assessment. If the cracks are accompanied by a sagging or bowing of the ceiling, this is most likely due to dangerous unsupported loads balanced precariously above the ceiling. This typically occurs where botched structural alterations have been carried out, such as the DIY removal of chimney breasts and load-bearing walls.

Cracks that radiate outward from a central point in a spider web pattern are also serious and suggest a major crack has formed within the foundation of the building. This is a clear indicator that pressure has shifted up through the ceiling and into the walls, which can cause serious problems in future.

When you start to repair a ceiling crack, first lay down a tarp or sheet of plastic to protect the floors below from loose debris and paint dust. You should also remove any furniture that could be damaged by the work you’re doing.

Next, if you can get to the attic space above your ceiling, use the utility knife and five-in-one tool to pry off any loose debris or drywall compound from the damaged area. Make sure to wear a face mask and eye protection as you’re doing this.

Once you’ve removed any loose material from the damaged area, apply a strip of fiberglass mesh tape to all the cracks. Then, spread a thin layer of joint compound over the tape and smooth it down with your putty knife. Let the compound dry overnight before painting the area.


Mould thrives in damp conditions, which is why black spots or patches on the ceiling are a clear sign of a problem. If left untreated, it can spread rapidly and even deteriorate the building materials used to construct the roof or walls. As well as being unsightly, mould can also irritate those who live or work in the affected room, causing respiratory problems such as coughing, wheezing and itching. The musty odor produced by most forms of mould can also be difficult to eliminate.

Wet spots on the ceiling can be caused by a number of things, including roof damage or leaks, insufficient insulation or even condensation. If the damp areas have a brown shade, it’s often a sign of a leaking pipe from above or within the walls, which requires urgent repair. In some cases, the cause of the damp may be hard to pinpoint as the spot may not be directly over a leaky pipe. In these circumstances, it’s wise to open up the affected area and use a dehumidifier in the room to reduce moisture levels.

If the damp patches don’t have a brown colour, they’re likely to be caused by water stains rather than a leaky ceiling. It’s important to find and fix the source of the moisture before attempting to clean the damp patches as otherwise the problem will return. Once the stains have been cleaned, it’s recommended that the area is re-painted with a waterproof paint to prevent further problems.

Using the right cleaning solution is crucial to removing mold and mildew from your ceiling. A simple mixture of one part bleach to ten parts water is a great way to kill any growth and leave surfaces clean and fresh. You can also try a milder option such as white vinegar mixed with water. This can be applied with a cloth or spray bottle and, again, will be effective on most surfaces as long as the mould isn’t deep into the material. Make sure the room is well ventilated while using any of these products and wear a face mask to avoid breathing in the spores.


When water damage is severe, it may be best to simply replace the entire ceiling rather than attempt a repair. This may be especially true if the drywall or insulation have been compromised or if you’ve discovered major structural issues, such as sagging, that require professional attention.

A small water leak left untreated can cause extensive deterioration and result in mold growth, sagging and even structural collapse of the ceiling and the rest of the home. If possible, you should first try to locate the source of the leak and correct the issue; this can involve opening up walls and using a dehumidifier to speed up the drying process. Once the affected area is dry, you can start to assess the extent of the damage.

Stained areas on the ceiling are often caused by wood tannins that have been deposited in the wet areas of the ceiling. Using a stain blocker primer before painting will help to seal the stains and prevent future problems.

Long, horizontal cracks in the ceiling that match up with wall cracks can indicate serious structural problems, and a professional inspection should be performed to determine the cause. These types of cracks are typically accompanied by a musty, stale smell that indicates the presence of mold.

If a water-damaged ceiling has been painted, it is usually necessary to strip and repaint the damaged area. A good oil-based or shellac-based primer will help to seal the surface and ensure that any new paint will adhere properly. A stain-blocker primer will also be beneficial to help prevent future problems with brown stains.

Water damage can be expensive to repair, but it can be much more costly to ignore the problem. If you notice any signs of water damage, it’s important to act quickly and hire a professional to make the repairs before more extensive and costly issues develop.

Proper waterproofing of the attic and basebments can help reduce the amount of moisture that collects in your ceiling during hot, humid weather. This can also reduce the amount of water that seeps into and damages drywall when it rains.
