How long does hardwood floor refinishing take in San Diego?
A typical 800 to 1,200 square foot refinish takes three to five days. One day of sanding, two or three coats of finish with drying time between each, then a cure period. Waterborne finishes allow sock traffic after 24 hours. Oil based finishes need five to seven days before furniture returns.

We refinished 1,100 square feet of 1962 red oak in Old Escondido this spring. Homeowner asked on Tuesday morning if she could sleep there Tuesday night. The honest answer was no, and that conversation happens on almost every job, so here is the whole schedule.
What happens on each day
Sanding is the loud day. Everything else is waiting.
| Day | What we do | Can you be in the house? |
|---|---|---|
| Day 1 | Rough sand at 36 grit, second cut at 60, edge work, nail set | No. Dust and noise from 7am to 4pm |
| Day 2 | Final cut at 100 grit, buff, tack, first coat | No. Solvent or coating odor |
| Day 3 | Screen between coats, second coat | No |
| Day 4 | Third coat on high traffic jobs | No |
| Day 5 | Walk with socks, light furniture back | Yes, with rules |
Stain adds a full day. A dark stain on white oak in a coastal house adds two, because the stain will not flash off in humid air.
Can you stay in the house while your floors are refinished?
Not on the sanding day, and not on any coating day. Our dust containment runs HEPA vacs plumbed to the drum sander and the edger, and we still pull fine oak dust out of the air for hours after the machines stop.
The coating is the bigger reason. Even a low VOC waterborne finish puts vapor in the air overnight, and walking across a floor at hour six leaves permanent prints.
Families with kids or dogs usually book three nights somewhere else. Single people with a second story sometimes camp upstairs if we can seal the stairwell with plastic and run a negative air machine. We have done that in Rancho Santa Fe more than once.
Oil based vs waterborne finish drying times
| Waterborne (2 component) | Oil based polyurethane | |
|---|---|---|
| Dry between coats | 2 to 4 hours | 8 to 12 hours |
| Sock traffic | 24 hours | 48 hours |
| Furniture back | 3 to 4 days | 5 to 7 days |
| Rugs down | 14 days | 30 days |
| Full cure | 7 to 14 days | 30 days |
| Color over time | Stays clear | Ambers noticeably |
We run waterborne on roughly 80 percent of jobs now. The amber shift on oil looks great on old red oak and terrible on white oak that the homeowner picked for its gray undertone.
What actually slows a job down
Coastal humidity is the main one. When relative humidity sits above 65 percent, which it does in Encinitas and Del Mar through most of a marine layer morning, coats take half again as long to accept a screen. We schedule those jobs to start early and we run dehumidifiers.
- Loose boards that need face nailing and filling before the second cut
- Old shellac or wax that gums 36 grit paper and doubles abrasive cost
- Pet stains that went through the finish into the wood, which no sanding removes
- Staples from carpet pad, hundreds of them, all pulled by hand
- Stair treads, which add a day on their own
That last one surprises people. A straight run of 14 treads is a full day of hand sanding and detail work because a drum sander cannot touch it. See our stair cost breakdown for how that prices out.
What we charge
Sand and refinish runs $3.50 to $5.50 per square foot in San Diego County. Stain adds $0.75 to $1.25. That 1,100 square foot Escondido job came in at $4,620 with no stain and two coats of waterborne.
Under 400 square feet we charge a minimum, usually around $1,800, because the setup and the machines cost the same whether the room is small or large.
Floors that have been sanded three times already may not have enough wear layer left. We check with a nail pull at a heat register before quoting, and if the tongue is close we say so. There is more on that call in our post on refinishing versus replacing, and the full process is on our sanding and refinishing page.
One more thing about the Escondido job. She moved the piano back on day four against our advice, and the caster left three dimples in a finish that had not hardened. We buffed and recoated that section for free. Wait the week.
