When attending to Gyprock ceiling repair works, we firstly ensure that there is an adequate two (2) stage fixing in place; both adhesive and ceiling fixings applied at the regulatory intervals.
Poorly installed Gyprock ceilings are unfortunately a common occurrence here in Perth and are not installed to Standard. Contributing factors to poorly installed ceilings can include:
- Fixings not applied at standard intervals.
- Entire stages of fixing not carried out.
- Installation of the Gyprock ceiling installed to outdated Code/Standard.
Was your Gyprock ceiling installed a long time ago? If so, your ceiling may now require maintenance work, bringing your ceilings up to current AS/NZS Standard.
The Repair Standard
There are multiple Standards in place to ensure that Gyprock ceilings are installed correctly, optimising the lifespan of ceilings with minimal maintenance.
One of the more recent Gyprock Ceiling installation Standards is Standard ref: ‘AS/NZS 2589:2017’, introduced in 2007 and revised in 2017.
Home owners and builders were discovering visible ‘peak lines’ appearing in their Gyprock ceilings. This condition would worsen over time, with joints of Gyprock sheets eventually cracking and parting.
Subsequently, Gyprock ceilings must be ‘back-blocked’ at standard intervals via the internal roof cavity, providing structural integrity and preventing cracking along the joints of a Gyprock ceiling.
Unfortunately, even at a time when such Standards exist in Perth, we still encounter workmanship that has failed to adhere to Standards such as AS/NZS 2589:2017, albeit relevant at time of construction.
In such cases and in our opinion, we believe this may be due to the fact that crawling around in a roof cavity is somewhat of a ‘thankless’ task, which may never be inspected or viewed by the Client. However, these hidden stages of work have proven to be critical in the installation process of Gyprock ceilings.
Sagging Gyprock Ceiling
Below is an example of a sagging Gyprock ceiling. As you can see, the ceiling is being supported by the garage door steel frame. Had the frame not been in place, the ceiling would have undoubtedly collapsed.
In this case there were several possible issues that could have contributed to the failure of the ceiling:
- Joist spacing exceeding 600 mm
- Insufficient fixtures
- Vibration of garage door
Customer was advised that issues identified in one section of property are usually indicative that issues may be consistent throughout.
Here at Pinnacle Roofing & Ceiling Services, we feel it is our duty to advise Customers of the condition of their Gyprock ceiling and if their ceiling has any current Standards not satisfied. Follow our Youtube for more videos on ceiling repair issues.
