Your Hardwood Floor Is Not Just 'Hardwood' and the Grade Changes Everything
A homeowner had 5-inch wide-plank select grade white oak throughout their first floor, site-finished with a custom walnut stain. The insurance estimate priced 3-1/4-inch No. 1 Common pre-finished red oak. Same word, "hardwood," on the line item. $7 per square foot difference. On 600 square feet, that's $4,200 the estimate was short.
Grade determines price more than species
Hardwood flooring is graded by the National Wood Flooring Association based on appearance. Select grade, also called clear grade, has minimal knots, consistent color, and a clean uniform look. The manufacturer discards more lumber to produce it, which is why it costs $2-$4 more per square foot than lower grades.
No. 1 Common has some character marks, small knots, and moderate color variation. No.
2 Common has visible knots, mineral streaks, and significant variation. Rustic or cabin grade has the most character and is the least expensive. On a 500-square-foot replacement, the difference between No.
1 Common at $6 per square foot and select at $9 per square foot is $1,500 just in materials. Your insurance should pay for the grade that matches your existing floor. If you have a clean, uniform floor with no visible knots, that's select grade and the estimate should reflect it.
- Select/Clear: minimal knots, uniform color, clean appearance ($8-$14/SF materials)
- No. 1 Common: some character, small knots, moderate variation ($6-$10/SF)
- No. 2 Common: visible knots, mineral streaks, significant variation ($4-$8/SF)
- Rustic/Cabin: most character, mixed widths sometimes, least expensive ($3-$6/SF)
Species is not interchangeable
Red oak is the most common residential hardwood at $4-$8 per square foot for materials. White oak is harder, more water-resistant, and runs $5-$10. Maple is dense with a smooth, light appearance at $6-$10.
Hickory is one of the hardest domestic species with dramatic grain at $6-$12. Walnut is a premium dark hardwood at $8-$14. Cherry darkens beautifully with age at $7-$12.
Exotic species like Brazilian cherry (Jatoba) or teak can cost $10-$20 or more. These are fundamentally different products. They have different colors, grain patterns, hardness ratings (Janka scale), and how they age over time.

Width and finish method: the hidden cost multipliers
Plank width has a major cost impact. A 5-inch plank in the same species and grade costs 20-40% more per square foot than a 2-1/4-inch strip because wider planks require higher-grade lumber with fewer defects. A 7-inch plank costs even more.

This creates a seamless surface with no micro-bevels between planks, allows custom stain colors, and costs $4-$8 per square foot more for the sanding, staining, and finishing labor. Pre-finished floors arrive from the factory with the finish already applied. They are faster to install but have small bevels between planks and limited stain options.
The visual difference is obvious. If your floors are seamless with no bevels, they are site-finished and the estimate should reflect that premium.
| Variable | Standard option | Premium option | Cost difference (500 SF) |
|---|---|---|---|
| Species | Red oak ($5/SF) | Walnut ($12/SF) | $3,500 |
| Grade | No. 1 Common ($6/SF) | Select ($9/SF) | $1,500 |
| Width | 2-1/4" strip ($6/SF) | 5" wide plank ($8/SF) | $1,000 |
| Finish | Pre-finished ($3/SF install) | Site-finished ($7/SF install) | $2,000 |
Document before demolition destroys your evidence
Once the old flooring is ripped up and tossed in a dumpster, your proof is gone. All of it. Before any work begins, measure the plank width with a tape measure and write it down.
Look at a cross-section at a transition, threshold, or floor vent to determine if it is solid wood all the way through or a thin layer over plywood. Note the species by examining grain and color. Take close-up photos showing the grain, color, character marks or lack thereof, and the plank width.
If you have original purchase records or know the brand and product line, include that. Then compare every detail to your insurance estimate. If the estimate says '3-1/4 inch common grade pre-finished oak at $7 per square foot' and your floor is '5 inch select grade site-finished oak at $14-$18 per square foot,' present the discrepancy with your photos and measurements.
The evidence speaks for itself.
Quick-check your estimate
- Measure plank width with a tape measure (2-1/4 inch strip vs. 3-1/4 inch vs. 5+ inch wide plank)
- Examine a cross-section at a transition to confirm solid vs. engineered
- Identify the species (oak grain is open and prominent, maple is smooth and tight, walnut is dark with swirl)
- Note the grade: select has minimal knots and uniform color, common has character marks and variation
- Determine if the floor is site-finished (seamless, no micro-bevels) or pre-finished (beveled edges between planks)
