Flooring for Interior Designers

By reconciling the build-ups before either material is ordered, because once thicknesses are fixed the transition is whatever the difference happens to be. The governing limits come from Section 303 of the 2010 ADA Standards: up to ¼ inch may be vertical, ¼ to ½ inch must be beveled at no steeper than 1:2, and over ½ inch has to be ramped. Underlayment, mortar bed and plank thickness are all levers, and they are cheap to adjust on paper and expensive to adjust on site.

Specify the cut whenever the grain character matters or the plank is wide. Rift and quartersawn oak reads as straight, calm, linear grain with no cathedral figure, and it is also about twice as stable across the width — the Forest Products Laboratory gives American white oak a radial coefficient of 0.00194 against 0.00376 tangential. Plainsawn is entirely appropriate for narrower boards in a well-conditioned house, and it is the more affordable and more figured choice.

It will move seasonally, and how much is predictable from the plank width. A two-point moisture-content drop narrows a plainsawn white oak board roughly 0.024 inch at 3¼ inches, 0.038 inch at 5 inches, and 0.056 inch at 7½ inches. Engineered construction and a rift or quartersawn face each cut that substantially, and controlled indoor humidity cuts it further. Wide plank is achievable — it just has to be bought as a system rather than as a width.

Yes — we work from the finish plan rather than from what is quickest to lay, including racking direction, pattern layout, and where the field is set out from. Where a drawn layout will collide with the room's geometry or a substrate condition, we raise it and propose the alternative before material is cut, so the decision stays yours rather than becoming an installer's improvisation.
