Frequently Asked Questions
Measure the length and width of each room, multiply to get square footage, then add 10% waste for standard installations or 15% for diagonal or herringbone patterns. Divide by box coverage to determine boxes needed. Always round up to the nearest whole box.
Solid hardwood is a single piece of wood from top to bottom, can be sanded and refinished multiple times, and lasts 50-100 years. Engineered hardwood has a real wood veneer over plywood layers, is more stable in humid conditions, and can be installed below grade.
Underlayment is recommended for hardwood flooring to reduce noise, provide moisture protection, and smooth minor subfloor imperfections. A moisture barrier is essential for concrete subfloors, especially for solid hardwood installations on or below grade.
Narrow planks (2.25-3.25 in) work well in small rooms and traditional homes. Wide planks (5-7 in) make rooms appear larger and are popular in modern designs. For best results, match plank width to room size and architectural style.
Engineered hardwood can be installed directly over concrete with a moisture barrier. Solid hardwood is not recommended for below-grade concrete installations due to moisture issues. Always use a vapor barrier and check moisture levels before installing any wood over concrete.
