You can often spot early signs of subfloor issues by paying attention to how your floor looks, feels, and sounds:
Unusual noises: Squeaking, creaking, or bouncing underfoot can indicate a loose or weakened subfloor.
Soft or spongy areas: Floors that feel soft or give slightly when you step on them may have moisture damage or rot—especially near kitchens, bathrooms, or exterior walls.
Uneven surfaces: Dips, slopes, or raised areas can signal that the subfloor is no longer level. Try rolling a small ball—if it moves on its own, the floor may be uneven.
Visible flooring issues: Cracked or hollow-sounding tiles Warped, buckling, or separating wood/laminate Damp or musty-smelling carpet
Signs of moisture: Musty odors, damp spots, or discoloration often point to trapped moisture beneath the floor.
Underfloor damage (if accessible): From a basement or crawl space, look for dark stains, mold, or crumbling wood.
Pay extra attention to high-risk areas like around toilets, sinks, and appliances, where leaks commonly occur.
If you notice any of these signs, it’s important to address them before installing new flooring. Repairing subfloor damage afterward can be costly and disruptive. Not sure what you’re seeing? We can carry out a professional inspection and recommend the best solution.
