Cavity Flashing & Lintel Replacement
A common and major building defect is defective cavity flashing due to poor initial construction practises. Cavity flashing replacement must be carried out by a competent and experienced team that will maintain the structural integrity of the building. We also replace the arch bar and lintels with minimal impact to the surrounding façade, by using the appropriate propping and installation methods.
Arch Bar & Lintel Replacement
Generally, this is required as a result of rusting of the existing steel lintels or severe spalling of reinforced concrete lintels. If left long enough, the lintel will change its volumetric size as a result of the rusting process and eventually will lead to unsightly cracking of the building or even a worse structural deficiency in the building.
Unicorn Building has been involved in many projects where head flashings and lintels above doors and windows require replacement.
