RHM Building Innovations

Legit the worst building company I have ever dealt with. I wish I could give negative stars. Over $25K for a 9.5x6.5m shed with full insulation on the walls and ceiling. Used a sub-contractor without discussing it with us, then claimed they didn't use one. The shed had significant leaks that resulted in damage to furniture, shelving and other items stored on the shelving. It took RHM 3 attempts, drawn out over 2 years, to resolve.

The cause of the leaks was the peaks of the roofline was actually lower than the roofline over a metre before the peaks, so water was pooling at the 'peak', running in under the barge caps and then tracking everywhere behind the insulation.

RHM's fix was just to pump ludicrous amounts of silicone under the barge cap to stop the water ingress.

Within a year, the insulation was falling apart. I had a shed insulation manufacturer inspect it and they confirmed the insulation was ' factory seconds' material.

RHM tried to blame this on the sub-contractor they used.

They eventually replaced the insulation in the ceiling, but not the walls.

6 years on from the build and the wall panels on one side are rusting and the powder coating is bubbling off as the rust is growing under it.

RHM are blaming it on BlueScope/Lysaght, the sheet manufacturer claiming it's a product defect.

I've had the issue inspected by multiple people, including BlueScope and I am also a marine corrosion expert. The root cause is the installation of the panels is not in accordance with the installation manual from BlueScope.

It states the sheets must not be in contact with the ground or with any concrete. That is, it must have an airgap from the bottom of the sheets and the back of the sheets.

The sheets are installed hard on the concrete pad and are pulled hard against the rise in the concrete that prevents water ingress into the shed. The insulation is also hanging out from under the sheets, so this hold water there for extended periods too.

RHM have cut off all contact, despite BlueScope confirming the shed build is not compliant and the 25 year product warranty is void.

I'm over 7 years on and have no resolution to multiple issues.

The business has continued on the the owner's son and his wife and they are no better than the Father and mother. They taught their son well.

A disgusting operation that I would not trust to build a flat pack shoe rack.

On to QCAT.
