Hardwood can arrive with its finish already applied at the factory, or be sanded and finished in your home after it is installed. Here is how the two compare.

The Short Answer

Choose prefinished if speed matters most and you like one of the factory colors. Choose site-finished if you want a custom color, a flat seamless floor, a pattern floor, or a perfect match to the wood you already have.

How Each One Works

  • Prefinished: the boards are stained and finished at the factory. They are installed, and the floor is ready to use right away, with no sanding on site.

  • Site-finished: raw, unfinished boards are installed first. Then the whole floor is sanded flat, stained if you want color, and coated with finish in place. Expect several days of work and drying time.

Why Site Finishing Suits Pattern Floors

Herringbone, chevron and other parquet patterns put many short ends and edges next to each other. Sanding the whole floor flat after installation removes tiny height differences and lets the finish run continuously across every joint. That is why our pattern flooring, like our herringbone, is sold unfinished. See parquet flooring patterns explained for the options.

Custom Color and Matching

With a site-finished floor, the color is mixed and tested on your actual boards, in your light. That gives you a far wider range than any factory line, and it is the most reliable way to blend new flooring into an existing floor. Cut matters too: straight-grained rift and quartered white oak takes stain more evenly than plainsawn.

Odor, VOCs and Healthier Finishes

Site finishing used to mean days of strong fumes. Today, zero and low VOC oils, hardwax oils and water-based finishes make it far more pleasant to finish a floor inside an occupied home. Eco-friendly finishing is what we specialize in. See our green-friendly finishes.

Over Concrete or Radiant Heat

The finish type is a separate decision from the board construction. If your floor goes over a slab or radiant heat, read engineered vs. solid hardwood first, then decide how you want it finished.

How to Choose

  • Pick site-finished for custom color, a pattern floor, a seamless look, or matching existing floors.

  • Pick prefinished when you need to move back in fast and a factory color works for you.

  • Either way, plan the finish around how you live: matte and satin sheens hide wear better than gloss.

Quick Answers

What is the difference between prefinished and site-finished hardwood?

Prefinished boards get their stain and finish in a factory and are ready to use once installed. Site-finished floors are installed raw, then sanded flat, stained and finished in place in your home.

Which looks better, prefinished or site-finished?

Site-finished floors are sanded flat after installation, so the surface is smooth and continuous with tight, sealed seams. Prefinished boards usually have small beveled edges, which create a visible line between boards.

Is site-finished hardwood worth it?

It is worth it when you want a custom color, a flat seamless surface, a pattern floor like herringbone, or a perfect match to existing floors. Prefinished makes more sense when you cannot leave the space for several days.

Does site finishing mean strong fumes?

It depends on the finish. Many traditional finishes give off strong odors, but zero and low VOC oils and water-based finishes greatly reduce fumes in your home.
