Now after about 9 weeks, I have noticed a few things happening to the floors:
1. Attached is a picture of the floor area near the kitchen. The boards that are closest to the kitchen are cupping/curling. Not quite sure the right term but looking at it from an angle it has noticable cupping at the joints. It is not happening everywhere but only in a certain area...for now.
2. I find gaps as big as 1/4 inch wide in high traffic areas along with smaller ones forming in other areas.
I contacted the contractor to inspect and repair since there has only been normal living happening with no floods etc...
They immediately concluded that it was water damage and would cost $$. Definetly a cash grab. They inferred that it could of been my fault since they did not live there. They obviously have no benefit in admitting any installation error.
My hypothesis is that there is excess moisture below the floor. (it is concrete since it is a 7 year old condo). I know that underpadding was installed but not sure about vapour barrier. The gaps are caused by improper measurement or too much space near baseboards.
My quesiton is it my responsibility that this has happened and should the contractors be held responsible? What are ways to prove this since I have not yet talked to the main owner. (request moisture test?) He seems reasonable but the contractors likely told him it was water damage and not their responbility. Trying to form an action plan before I talk to him in the next few days. I'm no expert so I shouldn't have to argue the cause, just looking for ways to determine accountability.
Appreciate any input from people that faced similar situations or specialists that have seen this before.
Appreciate your help!
