Do limited hollow-sounding spots under timber floors need repair?
From a professional specification perspective:
Limited hollow-sounding spots under individual boards without vertical movement typically need no remedial work. These are common in adhesive-fixed floors over concrete slabs due to normal slab undulations of up to 3mm over 3m. Floor Sanding Australia can assess whether hollow sounds in your floor are within normal tolerances.
