The hardwood came from Quickstyle...paid like 4700 incl installation for around 550 SF of engineered walnut. Do you think that was too much?
I did contact the contractor and they said they will try to fix it by screwing the loose boards to the concrete straight from the surface... I don't think this will be a feasible option as there will be A LOT of screws all over the surface of the floor. The thing is that he cannot even guarantee that this will fix my problem.
Do you have any suggestions as to how to fix it? Also, have you seen any problems similar to mine in the past?
Hypothetically, if condo management allows nail down solution, would you recommend it? Or would you still recommend the glue solution?
