Hey stackexchange community,
Not necessarily a DIY question- but thought I’d ask just in case, since we’re a little desperate. We have a fairly dramatic case of hardwood floor wood warping currently happening in our home. The hardwood floor was installed around 5 months ago onto all rooms of the ground level in our home; for an initial period of approximately one month, the floor was fine, and remained level throughout. Since then, the warping has progressively been lifting the floor higher and higher in the centre of the rooms that the boards are installed in, running parallel to the board direction. We want to put a stop to it as soon as possible, but aren't really sure how to proceed, so any advice folks here have is greatly appreciated.
As to the 'why' - we've recently uncovered a damp issue in the corner of one of the rooms that the boards start at. We didn't think this damp was particularly bad...though the warping has spread clear out of the room with this damp and deep into the main living room, which we believe to be dry underneath. We're not sure on whether this damp is causing this warping, or whether there is something wrong with the installation itself. Underneath the oak hardwood floor is a wood underlay (https://www.diy.com/departments/volden-5mm-wood-fibre-laminate-wood-underlay-panels-6-99m-/5063022038852_BQ.prd), timber boards, and then concrete.
We really liked the floor when it was level. Is there anything we can do to save it?
(P.S. we're handling the damp issue asap, separately)
