Can my existing floor be sanded and refinished?

Not every timber-looking floor can be sanded. I first identify whether the surface is solid timber, engineered timber or a decorative layer on another material. Laminate, hybrid and vinyl surfaces should not be treated like solid timber. Looking at the colour alone is not enough to decide.

For a timber floor, the useful question is how much usable wood remains. An engineered board may have a substantial timber surface or a very thin veneer. A solid board also has a limit above its joints and fixings, especially if it has been sanded before. Overall board thickness does not tell the whole story.

After more than 20 years in installation and repair, I still want to inspect the actual floor before recommending sanding. I look at accessible edges, previous repairs, loose boards, deep damage and the condition of the finish. Dampness or movement needs attention as well; sanding the top does not correct a problem underneath.

It is also important to agree on the finished appearance. Sanding can remove factory colour, surface brushing and some edge detail. A newly finished floor may therefore look different from the original product, even when the timber underneath is suitable. I would discuss colour and sheen rather than assume it will come back exactly the same.

If sanding is unsuitable, we can still consider whether cleaning, a compatible maintenance treatment, a local repair or replacement makes sense. Keep any product label or spare plank for the inspection. My aim is to find a workable option for the floor you have, without taking away more material than it can safely spare.
