Let There Be Light
Contrary to what it might seem, red oak flooring adds a lighter color to your home than white oak. Red oak is whitish/pinkish. White oak is consistently grayish, casting an overall darker color.
Scratches and Swords
At 1,350 on the Janka hardness scale, white oak is harder than red oak, which ranks 1,220. The difference is noticeable and means that white oak resists denting and scratching better than red oak -- but it's a double-edged sword. Scratches on white oak are easier to notice because white oak finishes to a glassier surface than red oak. The coarse grain pattern of red oak hides scratches better.
Shrinking and Pores
Red oak weighs less, has a more porous and open grain, and is more prone to shrinking than white oak. The closed-grain structure of white oak is less pronounced, easier to sand and adapts to finishing more readily than red oak. The pores of white oak are typically closed, making white oak more resistant to moisture than red oak. White oak is better than red oak if you're considering placing it in areas with high-moisture, such as on a porch. Red oak tends to stain if water penetrates the surface.
Go With the Grain
Grain patterns in red oak are bold and darker than white oak, and with traditional flame-patterns, evoke a complicated, busy appearance. White oak patterns are more subdued and straighter, evoking order and consistency.
If you're matching materials throughout your home, consider that most staircases, treads, moldings, trim, casings and other woodworking are typically manufactured using red oak. This is because of the economics and availability of red oak. To properly match everything up, red oak flooring is the best choice if you have a lot of existing oak trim around the house. White oak flooring with red oak trim is aesthetically disquieting.
The Color of Money
When comparing equal grades of white and red oak, you'll find that white oak is typically 10 percent to 50 percent higher in cost. There are three common grades of oak, all with different pricing: Clear is the most expensive, select is a close second and common is the cheapest. There are three grades of milling that affect cost: Flat or plain-sawn is the cheapest, quarter-sawn is more and rift-sawn is the most expensive. Any combination of grading and milling can make red oak more or less expensive than white oak. Prices typically reflect the grade and milling of the oak you choose, not the species.
