ProGuard Exteriors completed a spray cork house rendering transformation in Headington, Oxford, after the existing monocouche render to the rear of the property had failed. The homeowner wanted a professional repair and upgrade, with a more durable finishing system that would refresh the rear elevation while adding thermal benefits.
Overview
The rear elevation of the property was in need of attention after the existing monocouche render had failed. This left the wall requiring careful preparation, removal of defective material and a suitable repair process before any new house rendering system could be installed.
The homeowner wanted the rear of the property repaired and upgraded with a finish that offered improved durability and reduced future maintenance. Rather than selecting a standard silicone render finish, the customer chose CorkSol as the final product to take advantage of its thermal benefits over silicone render, while also benefiting from the current 0% VAT incentive available on qualifying energy-saving materials.
Our Response
Following an assessment of the rear wall, ProGuard Exteriors removed the failed monocouche render back to a suitable substrate. This was an essential stage of the project, ensuring the defective material was fully addressed and that the new system would be installed onto a correctly prepared surface.
Once the failed material had been removed, the team carried out the required repair works before installing a brand new premium base coat render system with reinforced mesh. This created a stronger and more stable foundation across the rear elevation, helping reduce the risk of future cracking and providing the correct surface for the CorkSol finish.
The gallery above showcases this Headington house rendering transformation, including removal of the failed monocouche render, repair works to the rear elevation, installation of a reinforced mesh base coat system, and the final CorkSol spray cork finish.
