How to Prevent Ceiling Sagging

Ceiling sagging is an issue that can have serious consequences if not addressed in a timely manner. Prevention is always better than cure and the best way to prevent ceiling sagging is through regular maintenance and inspection of your ceiling to note any changes in its condition. 

The Types of Ceilings

There’s two types of ceilings that we come across on a regular basis, plaster-glass and plasterboard. Both plaster-glass and plasterboard ceilings tend to sag when they are coming away from the roof joists and are at risk of coming down. 

Plaster-glass ceilings have straps that are placed over the roof joists and attach to the plaster-glass ceiling from behind. While they may last several decades, they do naturally degrade over time and break down. Once the straps break down they come away from the ceiling and roof joists and that’s when your ceiling starts to sag.

Plasterboard ceilings are the same material as Gyprock and are held in place by screws. If the screws are drilled too far into the plasterboard at installation, they break through the initial layer of paper and also the inner layer of the Gyprock, and that can cause the ceiling to be distressed. Insufficient amount of screws and adhesive at installation is another contributory factor for plasterboard ceilings breaking down.

What to Look Out For

Inspect your ceiling annually for signs of weakness or instability. Aside from sagging, some tell-tale signs of a distressed ceiling can be the cornices coming away from the ceiling or wall. With plasterboard ceilings, you may see screw-holes and cracks appearing, but this isn’t always the case. If there are visible signs of screw holes appearing, place your hands either side of the screw holes and gently push the ceiling up. If there is movement, this is a good indication it is coming down.

What Can You Do?

To prevent ceiling sagging and damage, it is important to inspect your ceiling annually and look out for any weaknesses or stability issues mentioned above. If you notice any of the signs, seek professional advice as soon as possible to stop the ceiling from deteriorating further. 

It is important that you seek professional help when you notice that your ceiling is sagging or has cracks in them as soon as possible. This is simply because as time passes the condition of your ceiling will continue to degrade. If the ceiling sagging is left as is for too long, it may no longer be possible to restrap it and a new ceiling will have to be installed. Not to mention the possibility of having the sagging ceiling falling on you! At the very least, the ceiling may be able to be saved, but will not be able to go all the way back up into its original position.
