rajeip in Toronto

I bought Landmark house with 2 1/2 story in 2012 and noticed leaky basement wall within an year and talked to their warranty adviser. She just told me your home humidity is too high so open the windows when temperature is warm. Their inspector came in one day opened the insulation in basement and came on second day to check but no problem with plumbing and said it's design fault and when they will redesign will let us know. Nothing happened till now after seven years. I am running HRV exhaust fan 24/7 and two dehumidifiers 24/7 but still no solution. All winter I can't able to open any windows because of ice buildups. thye installed the tree and replace the tree second times but still not growing so looks like the problem with preparation of land.
