Sagging ceiling repairs Perth
Sagging ceilings Perth. Don't wait for it to fall.
Most sagging ceilings in Perth don't need to come down. Fibreglass restrapping lifts them back, locks them in place, and carries a 10-year warranty. No mess, no pulling your ceiling apart.
What we do
Why sagging ceilings happen — and why you shouldn't leave them.
All ceilings move over time. In Perth homes, the two most common causes are adhesive failure in older plasterglass ceilings and fixing failure in newer gyprock ceilings. Both happen slowly, which is why most homeowners don't notice until the visual signs appear.
The problem with waiting: if a sagging ceiling falls, insurance typically does not cover the damage. Insurers classify ceiling failure as a maintenance issue. A ceiling that has fallen costs two to three times more to repair than one that was caught early — plus the years of roof dust that come with it.
The good news is that most sagging ceilings don't need to come down. Fibreglass restrapping can lift and lock them back as a permanent repair, on both gyprock and plasterglass ceilings.
Signs your ceiling is sagging
- Shadow lines or cracks running across the ceiling
- Visible join lines between sheets
- Screw holes pushing through
- A bow or dip in the middle of the room
- Cracks near the cornice line
- Movement when you push on the ceiling
- Cracking or popping noises
Quick check: measure floor-to-ceiling near the cornice, then again in the middle of the room. If the middle measurement is shorter, the ceiling is bowing.
Two ceiling types
Gyprock or plasterglass — the repair differs.
Gyprock (modern homes, post-1990)
Gyprock is fixed to rafters with adhesive and screws. When screws back out or adhesive breaks down, the sheets begin to drop. We re-screw and add fibreglass straps from the roof space — one strap per sheet — as a permanent repair. Most gyprock jobs are done in a day.
Plasterglass (older Perth homes, pre-1990)
Fibrous plaster ceilings were held with saddle straps — often coconut husk or early fibreglass. Perth's dry climate makes them brittle over time. We enter the roof cavity, move insulation clear, and install new fibreglass rovings to restore the bond between ceiling and joists. This is the only correct repair for plasterglass.
The repair
Restrapping: the right repair for a sagging ceiling.
Ceiling restrapping is the correct repair for both gyprock and plasterglass. It is done from the roof space — no demolition, no tearing down the ceiling you have. We enter the cavity, lay fibreglass straps to every sheet or wherever the ceiling needs them, reinstate the insulation, and leave it set. The finished result is a ceiling that is locked back where it belongs.
Every ceiling we restrap with fibreglass carries a 10-year workmanship warranty. If there is a problem with our strap work, we come back and fix it.
Quick check
Measure floor-to-ceiling near the cornice, then again in the middle of the room. If the measurement is shorter in the middle, the ceiling is bowing. That is the first thing to look for.
