It's been over 2 1/2 years since we first noticed the flooring troubles. The original installer claimed he had done everything right and the problems we were having (floor humping up, and large cracks) were because we weren't dehumidifying or humidifying the house properly. Well, it's impossible to control the humidity in a house to the extent he needed. He actually had told us to turn on the floor heat at the same time as the air conditioner (floor at 26C and air con at 22C). Besides wasting energy, it was only a temporary solution.
Finally, the manufacturer, TORLYS, acknow;edged the floors were improperly installed and agreed to provide replacement flooring and cover the labour to remove the old flooring and install new stuff.
The new flooring was delivered this morning. The installation starts tomorrow. The first phase will cover the master bedroom and kitchen and family room area. The we get to move all that furniture back and empty the dining room and spare bedrooms.
Hopefully this will go smoothly (cross your fingers!).
