1. Visible Scratches and Dents: Over time, scratches and dents can accumulate, especially in high-traffic areas. If they’re extensive and unsightly, it may be time for refinishing.
2. Discoloration or Fading: Sunlight, moisture, and normal wear can cause hardwood floors to fade or discolor. A faded floor may have lost its protective finish, making it more vulnerable to damage.
3. Water Damage or Stains: Water stains and dark spots indicate moisture has penetrated the finish, often meaning the wood itself may need attention.
4. Splintering or Rough Spots: Floors that feel rough or have splinters indicate wear beyond just surface scratches.
5. Wax Buildup (if previously waxed): If your hardwood has a dull or filmy appearance due to excessive wax buildup, refinishing can restore its natural shine.
6. Age: If it’s been more than 7-10 years since the last refinish, it may be time, even if the floor looks fine. Over time, the finish wears away and may no longer be protecting the wood.
Considerations:
• Traffic Levels: High-traffic areas like entryways may need more frequent refinishing than lower-traffic rooms.
• Refinishing Limits: Solid hardwood can usually be refinished multiple times, but engineered wood may have a limit due to its thinner veneer.
If your floors show any of these signs, a full sanding and refinishing can rejuvenate them. However, if wear is light, a screen-and-recoat (a light sanding and new finish layer) may be enough.
