Most solid hardwood floors in Chicagoland homes are three-quarter-inch oak, and that thickness is good news: a solid floor can be sanded and refinished several times over its life. Scratches, worn traffic lanes, gray boards, and an old orange finish are all surface problems, and a full sand-and-refinish takes the floor back to fresh wood.
Refinishing makes sense when the boards are still tight and flat, the wear layer above the tongue is thick enough to sand, and damage is limited to the surface or to a few boards we can replace and blend in. It costs a fraction of new flooring, and it's the moment to change your stain color completely.
Replacement makes sense when boards are cupped or buckled from long-term moisture, when an engineered floor's wear layer has already been sanded through, or when the subfloor itself is failing. In those cases new boards on a properly prepared base are the only lasting fix.
The quickest way to know is to have someone pull a floor register, look at the board profile, and check the subfloor. That's what we do at every free estimate — and if a refinish will do the job, that's what we'll recommend. Ask about 15% off the refinishing of your next floor.
