7 Signs of Hardwood Floor Water Damage

Whether your home has suffered a flooding incident in the past or you’ve moved into a new home with some creaky wooden floors, knowing the signs of hardwood floor water damage in a Sterling home can help you maintain this stunning feature of your home for years to come. 


That’s why United Water Restoration Group of Sterling would like to discuss seven key signs of hardwood floor water damage that could appear in your home.


Staining or Discoloration

Your hardwood floors have a grain pattern that makes the flooring unique, but if you have almost-black stains, dark discolored spots, or fading, this could be a sign of prolonged water damage. Be sure to inspect your floors regularly for any new spots you haven’t seen before to catch damage as soon as you can.


Soft Floorboards

If your floors feel a bit too bouncy or like they’re going to break, then you could have rot in your hardwood floors from water damage. This typically means that the sub-flooring is damaged, too. All of the affected planks will need to be replaced, and the sub-flooring underneath will need to be cleaned and dried to remove excess moisture.



Swelling occurs when hardwood absorbs a large amount of water. When these planks swell, they push against other planks and cause them to lift up, making an uneven surface. More water could enter into these new cracks, leading to moisture buildup under the flooring and more water damage.


Cupping or Buckling Boards

Some planks won’t swell but rather they’ll bend or warp, leaving an uneven surface. This can also lead to small spaces through which more water can come in and cause even more damage.


Lifted Nails or Floorboards

One of the first signs you may notice is lifted boards or nails that stick out, which could be signs of swelling planks nearby. 


Mold Growth

Black, gray, green, and other discolored splotches on or between planks could be mold, a sign of prolonged water damage.
