What you pay for with floor sanding in Madison
Sanding removes the old finish and a thin layer of wood, so scratches, stains and old color come out with it.
A traditional sanding takes off about 1/32 to 1/16 inch (Hardwood Floors magazine), and a skilled pro averages 1/32 to 3/64 inch during a total resand (Wood Floor Business). Those slices add up, so every sanding is a trade: a better surface now, a little less wood later.
HomeAdvisor lists sanding as its own step at $0.50 to $3 per square foot, before repairs, stain and finish (HomeAdvisor*), and add those steps and you get the full price in our cost guide.
How the machines work
- Drum sander. The big machine covers the open floor in straight passes with the grain.
- Edger. A smaller disc machine works along walls and under radiators. One guide starts the edger on the same paper as the drum before both move to a finer grit (The Home Depot).
- Hand tools. Corners, door thresholds and stair edges need a scraper or detail sander.
- Finer passes. Each pass uses finer paper to erase the scratches left by the one before it.
- Vacuum between passes. Most drum and edger sanders have built-in vacuums and dust bags (The Home Depot). Dust left on the wood shows up in the finish.
Where sanding goes wrong
- Sanding through thin wood. Use the sanding-count checker before you book.
- Uneven removal. The amount taken depends on flatness, stains, color changes and operator skill (Wood Floor Business).
- Going from dark to light. A big color change takes more wood off than a small one (Wood Floor Business).
- Nail heads showing between boards. These are called shiners, and they mean a floor has been sanded too far (Wood Floor Business).

Old finish, old wax and older Madison homes
If your floors carry many layers of old finish or wax, the Wisconsin Historical Society says a chemical stripper may be needed before a new finish goes on (Wisconsin Historical Society). Another trade article warns that wax can sit deep in the grain and between boards, so it suggests sealing with dewaxed shellac before urethane (Hardwood Floors magazine).
Sanding is also on the Wisconsin DHS list of paint-disturbing work, so pre-1978 homes need a lead-safe plan when a contractor is paid (Wisconsin DHS). Use our pre-sanding checklist before you hire anyone.
