25.01.2022 During the Corona virus epidemic we continue to operate taking precautions such as using hand steriliser before and after each appointment, trying to keep safe distancing and following the recommended practices. We still endeavour to complete inspections and reports within 48 hours of bookings; this is achieved every time providing we can access the property.

23.01.2022 Electrocution hazard Loose power outlets are dangerous not only from the risk of small fingers being poked in the gap but from stressed wiring coming loose and electrifying other elements such as copper piping in the wall cavity.

22.01.2022 This little post needs "airing" again. We see this constantly and each time we bring to a builder's attention we get the blank look and the response "but we always do it that way" . Yeah, guess what you always get it wrong!

07.01.2022 Sarking and Anti- Ponding boards We have recently raised an issue where sarking (Sisalation) has been laid under roof tiles, although the same also applies to metal roof cover. This is also applicable to Bushfire Attack (BA) requirements where sarking is specified, initially to prevent entry of sparks entering the roof space but would also collect any moisture that should be discharged into the gutter. The purpose of sarking... The purpose of sarking in to collect condensation and small leaks occurring inside the roof void. To this end sarking is specified where the run of roof tiles (Ridge to Gutter) exceeds 6 metres due to the high risk of tiles flooding and allowing stormwater to inundate the roof void. The purpose of anti-ponding boards Anti-ponding boards are used to carry the sarking from the top of the bottom course of roof tiles to the gutter. The sarking would otherwise sag behind the gutter/fascia and discharge any collected moisture into the eaves or where no eaves into the roof space. From the above it is clear that fitting sarking without anti-ponding boards renders the sarking unfit for purpose. Refer National Construction Code (NCC/BCA) Part 1.2.1, F2.2.2 and P2.2.2. Part 1.2.1 Suitability of materials Every part of a building must be constructed in an appropriate manner to achieve the requirements of the Housing Provisions using materials that are fit for the purpose for which they are intended. F2.2.2 Weatherproofing and dampness A building is to be constructed to provide resistance to moisture from the outside and moisture rising from the ground . P2.2.2. Weatherproofing A roof and external walls (including around windows and doors) must prevent the penetration of water that could cause- (a) Unhealthy or dangerous conditions, or loss of amenity for occupants; and (b) Undue dampness or deterioration of building elements. This is the reason tile manufacturers specify the use of anti-ponding boards where there is a risk of moisture ingress, typically on long roof lengths. The sarking folds over the fascia and back of the gutter (not shown in first diagram) The anti-ponding board prevents the sarking sagging and spilling the collected moisture into the roof void Stormwater discharging into eaves may run down the wall cavity where electrical points (light switches power outlets etc.) and light fittings in the eave lining can become wet and therefore fail. This moisture could also cause damp in the internal walls.
