Short answer
A hardwood floor that looks cloudy and dull with no soft spots has a finish problem, not a wood problem. Clean a hazy patch and watch it dry. Haze that clears while the floor is wet and returns as it dries is built-up floor polish, and that strips off without touching the finish underneath. Haze that stays, sitting in the walking path, is a worn finish, and that takes a screen and recoat rather than a full sand.
Tell wax buildup from a worn finish in 10 minutes
- Clean a hazy patch with your usual floor cleaner and watch it dry. Haze that looks good wet and returns when dry is a polish layer, not damage.
- Drag a fingernail across the haze. A visible mark or a slightly gummy feel means wax or acrylic polish is sitting on top of the finish.
- Rub a hidden corner with a rag and a little mineral spirits. Polish softens and lifts onto the rag, and a cured floor finish does not.
- Look at where the haze is. Buildup shows up everywhere you mop, and a worn finish shows up in the traffic path and in front of doors.
- Press the dull boards with your heel. Boards that feel soft, springy or raised have water under them.
- Look for gray wood, black stains and scratches you can feel with a fingernail. Gray means the finish is gone and the bare wood is exposed.
If the haze lifts with mineral spirits, a wax strip brings the floor back and the finish stays. If the finish is hard and intact but dull in the walkways, a screen and recoat fixes it in a day. If you find gray bare wood, deep scratches or black stains, the floor needs a full sand and refinish.
Repair or replace
| Situation | What to do |
|---|---|
| Haze clears wet and comes back dry, boards are hard | Strip the polish. A strip and neutralize restores the sheen and leaves the existing finish in place. |
| Finish is hard and intact but dull in the traffic path | Screen and recoat. One fresh topcoat over a scuffed floor costs a fraction of a sand. |
| Deep scratches, gray bare wood or dark stains | Sand and refinish. A recoat will not bond over bare wood or soak into a stain. |
| You want a noticeably different color | Sand and refinish. Color only changes when the floor goes back to bare wood. |
| Boards feel soft, springy or raised underfoot | Find the water first. Finish put over a wet subfloor fails and the boards keep moving. |
| Floor is laminate or luxury vinyl, not wood | Replace the planks. A floating floor has no finish to sand or recoat. |
What it costs
Runhome contractor estimates for stripping wax, recoating or fully refinishing a hardwood floor ran from $335 to $1,155 as of October 2026, including the trip and assessment.
| Option | Range |
|---|---|
| Strip built-up wax and polish, keep the existing finish | $335 to $700 |
| Screen and recoat the worn finish | $340 to $730 |
| Sand and refinish, main floor with a spot repair | $525 to $1,155 |
Can I do it myself?
Yes for stripping wax. Use a stripper made for wood floors, work a few square feet at a time, then neutralize and dry the boards right away. Test a closet first, because the wrong stripper softens the finish you are trying to keep.
Hire the recoat and the full sand. A screen and recoat lives or dies on an adhesion test and a wet edge, and a coat that does not bond peels off in sheets within weeks. A rented drum sander cuts waves and dish marks into a floor in seconds, and they show through every coat after.
What a contractor will ask you
Have these ready and you skip the back-and-forth.
- Whether the floor is solid or engineered hardwood, or a floating laminate or vinyl that cannot be sanded.
- How long ago the floor was installed or last refinished.
- What finish is on it now, if you know: older oil-based polyurethane, newer water-based, or wax and polish.
- Which rooms are in scope, the square footage, and whether you want the floor under rugs and heavy furniture done.
- Whether any boards feel soft, spongy or raised underfoot.
- Whether you are keeping the color or changing it.
- A wide photo of the room from a few steps back, showing the floor and the baseboards.
Common questions
- Will a screen and recoat get rid of the cloudy patches?
Yes, when the cloudiness sits in the finish and not under it. Screening cuts the top layer off and the new coat fills the dull micro-scratches. Haze from water trapped under the finish stays, and those boards need sanding.
- How long before I can walk on the floor and move the furniture back?
Walk on it in socks after about 24 hours with most water-based coats. Rugs and heavy furniture wait 5 to 7 days while the finish cures. Oil-based finishes take longer and smell for several days.
- Can I just keep mopping with a wood floor cleaner instead?
No, not once polish has built up. Most cleaners leave another thin film behind, so the haze comes back every time the floor dries. Stripping takes the whole stack off at once.
- Do I have to refinish the whole floor or just the dull room?
You can do one room, but expect a visible line at the doorway. Finish ages in both color and sheen, so fresh coating next to old shows. Stopping at a threshold or a doorway hides it best.
- Is a cloudy white patch water damage?
Usually not, when the boards feel hard and flat. Water-damaged wood goes gray or black and cups or lifts at the seams. White haze over solid boards is a finish or polish problem.
