Long term defects to a new home.
New home with long term defects. Inspected by Peter Weddell, owner/operator of Qld Home Buyers Inspection Service and Queensland Building Inspection Service, QBIS.
Open deck seepage problem:
Open balconies are most likely to give problems, no matter how well they are drained and water-proofed.
- Concealed drains are prone to blocking.
- Water-proofing is likely to crack over the long term from different rates of expansion and contraction.
- Seepage is most likely to occur to the living areas directly below.
New home with long term faults, recommended rectification:
Construct a roof above the platform with a decent eave overhang for protection. This will also allow the balcony to be more usable in hot and wet conditions.
Timber panels have been fitted over drains and water-proof barrier.
This balcony extends over a living area which is likely to allow seepage if not appropriately waterproofed below the floor tiles.
This is likely to allow seepage to the living area below, sooner rather than later.
- Closely monitor the ceiling lining below with a powerful torch, look for signs of paint peeling
- Check with a moisture meter, not long after rain periods.
- Remove the floor tiles.
- Fit flashing and a water-proof membrane then re-tile.
- Fit awnings to perimeter of the balcony that can be pulled down for protection, when necessary.
Insufficient clearances between timber walls and tiles:
The timber walls extend down to the floor tiles without appropriate clearances, this will allow seepage to cause rot to the concealed timber frame.
New home with long term defects.
- The most effective way to avoid this from happening would have been to have built the wall at a level higher than the floor tiles, during construction.
- The only economical solution (without removal of materials) would be to apply a sealant suitable for external use, closely monitor and reapply often.
