Solid Oak, Maple and Hickory Over OSB
Solid hardwood is nailed through the tongue into the subfloor, so the subfloor has to be up to the job. NWFA installation guidelines call for at least 23/32 inch OSB or 5/8 inch plywood under nail-down solid strip on joists 16 inches apart.
Many Milton homes meet that. Some have thinner panels or wider joist spacing, and we check before we quote rather than after the boards arrive.
Where the subfloor falls short, we add a plywood layer or recommend engineered instead. White oak and red oak are the most common species we install here, with maple and hickory close behind.
