Whilst taking up renovation works, in eight out of ten instances, it is seen that all is not well with the windows, and the decorative mouldings that lie above them. In most cases, they are found to be cracked to the point so much so that the lintel needs to be replaced.

 

The focus shifts on to the architects of the company that have taken up the responsibility of lintel replacement. The architects who oversee the task take up the onus of taking on the damaged lintel and replacing it using certain specific steps.

 

Well, the steps may vary a bit here and there, but the mainstay of the technique remains more or less the same. Hence, it will perhaps not be unwise to generically discuss the series of steps that the techies take to change or replace the lintel. 

  • At first, a solid scaffolding is set up to all the bay windows. Generally, the spots on the walls where the scaffolding needs to reach are marked beforehand for perfection.

 

  • Usually, cavity wall ties are installed within the beam zones. It is required for providing lateral restraints and for resisting the wall from bowing or buckling, once the lintel is removed for replacement.

 

  • Beams are installed to support the internal brickwork, just above the windows. Similar beams are mounted against the exterior of the walls, to resist any wall movement. It also prevents the occurrence of further cracking.

 

  • Now, it is time to remove the round decorative central section, along with the adjacent horizontal sections. Slots and chases are set up within the joints of the bed of the brickwork. This is a pretty crucial stage of the lintel replacement in Perth as this creates a masonry beam, which acts like a typical lintel, and thus holds the entire brickwork together above the affected window(s).

 

  • This method makes use of the existing roof rafters and thus provides lateral restraint to the upper part of the gable walls. The same process is then followed while addressing issues of the other bay windows of the gable walls.

 

  • The same method is used on the side elevation of the building.

 

  • Now, with the gable walls braced properly and supported adequately, it is time to start removing what is left over of the decorative moulding. This opens up the lintel that lies beneath. The beam may have stirrups that are spaced along the length and along the concrete that encases it.

 

  • This is the source of all the problems. The concrete fails to provide enough protection to the internal steel beams, which it surrounds. When the concrete is of inferior quality and is honeycombed, it allows the moisture to get into the concrete and corrode the steel beams, expanding them and resulting in the cracking of the decorative moulds.

 

  • With new lintel installed after removal of the old one, new brickwork is also constructed to provide the adequate beam support. It also makes sure that the repair work remains entirely concealed.
