Upstairs valve under bathroom sink "exploded" while away from home.
Half of upstairs and downstairs was flooded. Restoration crew came in
and ripped up all laminate flooring and carpet, cut holes in downstairs
ceilings, and brought in fans and dehumidifiers to dry everything up.
House is on a slab.
Now that the laminate has been reinstalled upstairs, the hallway floor
no longer seems level. I did not notice any unevenness when we were
walking on bare floorboards for two months, or even before the flooding
occurred. But now, there is a definite slope toward the wall.
Here are my questions/concerns:
--Is the problem with the reinstallation of the floor? On
reinstallation, a protective layer of plastic was installed before the
underlay. This was only supposed to be done downstairs, since the
house is on a slab. Would this extra layer of plastic cause a problem?
The original upstairs installation did not have this extra layer.
--Did the flooding cause some kind of shift in the house? If so, why
wouldn't I have noticed the slope when it was just bare floorboards?
--Was the slope there all along, and the flooding just made it worse?
The pattern of the flooding would indicate this possibility, since the
water never ran down the stairwell, but instead ran down the wall.
I am trying to figure out what to do (if anything) before the insurance
repair warranties expire. Thanks for your feedback.
