Matching a New Oak Floor to an Existing One: What to Send

Matching a new oak floor to an existing one: what to send the factory, how aging and wear change the old floor, and how to judge the sample beside it on site.

An extension, a second phase, a renovated wing or a replaced section: sooner or later a new oak floor has to sit next to one that is already installed. The old floor has had years of light, traffic and cleaning. The new boards will arrive fresh from the finishing line. The aim is a new floor that sits comfortably beside the old one, judged on a physical sample before production, not a promise that the two will be identical. This article covers what to send the factory, what changes in an installed floor over time, and how to review the sample where it matters: on site, next to the existing boards.

Decide what “match” has to mean

How close the new floor has to be depends on where the two floors meet. Agree this with the owner or designer before any sample is made.

SituationHow the two floors are seenWhat matters most
Separate rooms, door or threshold betweenOne at a time, rarely side by sideOverall tone and character
Same room or open plan, floors meet at a transitionSide by side, at a clear lineTone, sheen, texture and width
Boards replaced within an existing floorMixed into the old fieldEverything, including wear and aging

The first case is the most forgiving. The last is the hardest, because new boards are surrounded by old ones and any difference in tone, sheen or texture is seen at close range on all four sides.

What to send

The more of the existing floor the factory can see and measure, the more useful the first sample will be. Send as much of the following as you can.

A physical piece of the existing floor

A real board is the best reference, as explained in our article on custom color matching. For an existing floor, a few points are specific:

Photographs in daylight

Photographs support the physical piece. They cannot replace it, because cameras and screens shift color. Useful photos are:

Dimensions

Measure the existing boards and give the figures in inches and millimeters:

Our standard and made-to-order widths and thicknesses are listed on the Specify page. If the existing size is not among them, it can be reviewed and confirmed at quotation.

The profile

If the new boards will join the old ones directly, the edge profile has to fit. Note whether the existing floor is tongue and groove or square edge, and whether the edges are square or carry a micro-bevel. A photo of a board end in section, or an offcut that shows the tongue, is more useful than a description. Our standard profile is Tongue & Groove on all four sides, with square edge available on request. Where the profiles cannot meet cleanly, the installer may plan a transition piece at the junction instead. That decision belongs to the installer.

Texture, sheen and finish

Describe the surface as far as you know it: smooth or brushed, and how deep; how much the floor reflects light; whether it was finished in a factory or on site with an oil or lacquer. If original paperwork or carton labels survive, send a photo of them.

Why the existing floor no longer looks like it did

Oak changes after installation. The general effects are well known, though how far they go depends on the floor, the finish and the room:

Two practical points follow. First, decide whether the target is the floor as it looks today, in the main area, or the floor as it looked when new. These are different colors. Second, the new floor will also change after installation, and it will not follow the same path as the old one did. No one can promise how two floors of different ages will look together years from now.

When it makes sense not to match

Sometimes the better answer is to stop chasing the old floor:

Reviewing the sample on site

The sample is made with the intended production finish and should be judged next to the existing floor, not at a desk.

  1. Lay it on the existing floor, at the place where the two will meet.
  2. Look in daylight and under the room’s own lighting, from standing height and from a low angle.
  3. Judge tone first, then undertone, then sheen and texture. Our article on oak flooring color undertones helps describe the direction of a difference.
  4. Describe any adjustment by direction: warmer, cooler, lighter, more texture, lower sheen. We adjust and resample if needed.
  5. Approve in writing, with the full specification. The approved sample then becomes the master reference, which is also useful if a later phase has to match this one.

Working with Vu Uy Wood

We manufacture solid and engineered French White Oak flooring to buyer specification in Song Than 3 Industrial Park, Ho Chi Minh City, and have done so since 2006. When a new floor has to sit beside an existing one, we develop the color against the board you send, make the sample with the intended production finish, and keep the approved panel as the master reference. Send the board details and photos through our contact page. We normally reply within one working day.
