The WallGuard® Wall Sealer system is a three stage process that removes grime and unsightly organic growths from porous brick and stone claddings, and seals them against water penetration, which helps to improve home insulation.

The WallGuard® Wall Sealer system is applied by trained applicators and is supported by an Edwards & Hardy Roofing “No quibbles” WallGuard® Guarantee, that gives you assurance of a professional application with superior performance.


WallGuard® Moss and Grime Removal

WallGuard® Moss and Grime Removal eradicates Moss, Lichen and Grime from porous wall surfaces and neutralises live spores, thereby preventing future organic growth.


WallGuard® Deep Surface Cleaning

The WallGuard® Deep Surface Cleaning regime is customised for the condition and material properties of your wall cladding, and restores the surface finish to the highest possible standard and an “as new” appearance.


WallGuard® Wall Sealer

The WallGuard® Wall Sealer is applied to porous wall surfaces, using product and application techniques unique to the material properties of your wall cladding. The WallGuard® Wall Sealer is designed to slow down the weathering process by waterproofing the wall surface, which also helps to prevent the transfer of dampness and improve the thermal insulation properties of your home.


Porous wall claddings, such as brick and stone walls, that are not periodically cleaned and sealed can be effected by moss and lichen growth, which retain water and secrete acids into the wall. This damages the surface of the cladding and can lead to unsightly discolouration and cause dampness and coldness in your home. Sealing walls keeps dampness out and helps to achieve a cleaner, dryer and healthier home for your family.
Although nearly all property values increase over time, some of that value can be lost because of poor street appeal. Good presentation creates a “feel good” perception that will help you to maximise the value of your home.
You can easily self-test the porosity of your brick or stone wall cladding. If it darkens after rain or a light spray from your hose your wall cladding is at risk of the discoloration and dampness effects of organic growth. In particular watch for mould growth on the South and East facing sides of your Home where plants and trees touch or shade your property.
On completion of the WallGuard® program your walls will have an “as new” appearance. The timing between each of the three stages of the WallGuard® Maintenance program will depend on the condition of your walls at the outset of the process.
No. New or very clean walls can be treated with the WallGuard® Wall Sealer directly. Naturally, there is a cost advantage here and “prevention is better than cure”.
The application of the WallGuard® Wall Sealer product is not intrusive and it can be applied at any time following the construction of the Building.
Most porous, hard claddings can be treated including: Summer Hill Stone, Oamaru Stone, Hinuera Stone, Concrete Block, All types of fired Brick
It is likely that your WallGuard® treatment will be well under 1% of the cost of your home. Though the total cost will depend upon the size, complexity and overall state of your walls, it is a very small amount compared to the value that it will add. Your Edwards & Hardy representative will be happy to discuss our costs with you, so that you have a clear understanding of the services you are paying for.
