Strata Refurbishment


Significant value was added to this Fairlight unit block with an external refurbishment including rendering and waterproof protective coatings All timber windows were also refurbished.

Strata Painting


 This 5 storey building by Manly Beach had an  external repaint including all balconies.  External  access is required and achieved using scaffolding, swing stages and Cherry Pickers / Elevated Work Platforms.

Residential Painting


 High end residential properties such as these Neutral Bay town houses demand quality workmanship and finishing.

Commercial Painting


Commercial  properties require ongoing  maintenance to protect their value of the asset. Many businesses operate 6 or 7 days a week, so minimal interruption is essential when completing the maintenance.

Roof Membranes


Flat concrete roofs need effective waterproof membrance to prevent water penetration to top floor units. We are specialist waterproofing contractors.

Spalling Concrete Cancer


Spalling concrete or concrete cancer affect many concrete structures, especially coastal, within inadequate protection of the steel reinforcement. We are specialist concrete repair contractors. 

Residential Additions


Why move from the area you love. A first floor addition or renovation can give you a brand new house for your growing family. 

Building Repairs


We are specialists in building repairs such as;

  • Rotten timber
  • Rusted lintels
  • Leaking roofs
  • Water penetrations

Magnesite Floors


Magnesite floor toppings were widely used in unit blocks in the 1960's and 70's. We now know they can be corrosive to steel reinforcing. We are specialist repair contractors.

Balcony Balustrade Replacement


Many old balcony balustrades do not comply with current BCA requirements and are dangerous. As specialist remedial builders we are able to replace your balcony balustrades with new modern and stylish balustrades.

Strata Foyer upgrade


Council may impose a Fire Order requiring new fire doors, smoke detectors, emergency lighting and compliant stairwell balustrades. We are experienced in Project Managing the whole project. 

Fire Sealing


Council issued Fire Orders require the sealing of penetration between units and common areas. This is a Fire Dampener which will prevent a fire spreading from the top floor kitchen into the roof cavity.
