This home was originally constructed in 1998 and clad with a 60mm EIFS plaster cladding system (Insulclad). The Insulclad plaster system had performed well but the house did have some leaky building problems relating to the deck areas. The tiled decks were constructed at the same level as the internal floor level making it impossible to properly waterproof. The deck handrails had a timber capping top fixed with large nails through the waterproofing membrane. Timber pergola beams penetrated the plaster cladding system and provided a path for moisture to soak through to the framing timber.
The remedial design included removing the lounge deck structure and rebuilding the structure to achieve a 100mm threshold between the deck waterproofing and the internal floor level. The roof and lounge decks were drained to external gutters to eliminate the risk of flooding caused by internal drainage outlets blocking. A floating deck was installed to bring the deck level back up to the internal floor level and metal cap flashings were installed to the deck and stair handrail balustrades.
The opportunity was taken to remove a small walkway under the lounge deck and extend the two lower level bedrooms. A covered front entry was constructed along with upgraded insulation and new double glazed joinery. The cladding system selected was extra wide 230mm bevelback timber weatherboards painted in Resene Sonyx Paint.
Internally, the home was refurbished with a new kitchen, new carpet and full internal repaint.
