Hardwood floors should be sanded and refinished near the end of a home remodel, after drywall, trim, cabinetry and painting are finished but before appliances and furniture move back in. Doing it earlier almost always means scratches, dings and a second sanding you did not budget for. The team at Kanna Construction & Remodeling often reminds homeowners that since most refinishing runs $3 to $8 per square foot, getting the sequence right protects real money.
Where Floor Refinishing Belongs in the Construction Schedule
On a typical whole-house project, floors get sanded after the messy trades are gone. Drywall dust, tile cutting and paint spray all settle into raw wood, and a fresh coat of polyurethane will lock that debris in permanently. If you are planning a home remodel in San Diego with a general contractor like Kanna Construction & Remodeling, walking the space early allows you to map out where refinishing fits into the overall sequence of services before demolition even begins.
A sequence that works on most jobs looks like this:
- Demolition, framing, rough mechanicals with existing floors covered in rosin paper and hardboard
- Drywall, primer and first coat of paint on walls and ceilings
- Cabinet installation, since cabinets sit on subfloor or on the old finish, never on a brand-new one
- Sanding and finishing of the hardwood, with the house empty for 3 to 7 days
- Final paint touch-up, baseboards and shoe molding installed last
The one common exception is kitchens, where many builders run new hardwood under the toe-kick line before cabinets land. Talk through that detail early with your kitchen remodel contractor in San Diego so cabinet height, dishwasher clearance and flooring thickness all line up.
How Many Times Your Floors Can Be Sanded
A 3/4-inch solid oak floor has roughly 1/4 inch of usable wood above the tongue, which allows about four to six full sandings over its life. Engineered flooring is a different story: a 2mm wear layer tolerates one light sanding, while a 6mm layer can handle two or three.
Before you commit, pull a floor vent or lift a threshold and measure the board thickness. Floors with cupping, deep pet stains that reach the subfloor, or face-nailed boards with exposed nail heads may need board replacement rather than a straight refinish.
Water damage is the usual deal-breaker. If boards have crowned or the subfloor reads above 14 percent moisture, the problem needs to be solved before anyone brings in a drum sander.
Real Numbers: What Refinishing Costs
Most homeowners pay $3 to $8 per square foot for sand-and-three-coats, which puts a 1,000 square foot main level somewhere between $3,000 and $8,000. Stain adds roughly $0.50 to $1.50 per square foot, and repairs to damaged boards typically run $8 to $15 per linear foot.
Prices climb for parquet, herringbone, stair treads, and any floor that needs multiple passes to strip old shellac or adhesive. Before committing to the project, however, inspect the condition of your planks. As Sean, Lead Contractor at Kanna Construction & Remodeling, advises: “Before refinishing hardwood floors, check the wood’s thickness to ensure it has enough of a wear layer left to withstand sanding without damaging the planks.”
Compared with new flooring at $8 to $20 per square foot installed, refinishing is usually the better value on any floor with enough thickness left. That savings is often what funds the rest of a home renovation budget.

Choosing Between Oil-Based, Water-Based and Hardwax Finishes
Finish choice drives both the look and how long your family stays out of the house. The three options most flooring contractors offer differ in amber tone, cure time and odor.
- Oil-based polyurethane: warm amber cast that deepens over time, very durable, around $3 to $5 per square foot, but it off-gasses strongly and needs 24 hours between coats plus 14 to 30 days to fully cure.
- Water-based polyurethane: clear and non-yellowing, dries in 2 to 4 hours per coat, lower odor, costs about $1 more per square foot, and reaches full cure in 7 to 14 days.
- Hardwax oil: a matte, natural look that penetrates the wood instead of sitting on top, spot-repairable without sanding the whole room, though it wants re-oiling every 3 to 5 years in high-traffic areas.
If anyone in the house has asthma or chemical sensitivity, low-VOC water-based products are the safer pick. The EPA notes that indoor VOC concentrations can run several times higher than outdoor levels during and after finishing work, so ventilation matters as much as the product label.
Dust Containment That Actually Works
Dust-containment sanding systems capture most airborne particles at the machine, but no system is truly dustless. Expect a fine film on horizontal surfaces for a week afterward, which is exactly why sanding belongs before final cleaning and after new cabinetry is wiped down and taped off.
Practical protections to ask your crew about:
- Plastic sheeting with zipper doors at every room opening
- Negative air machines with HEPA filtration venting outside
- Taped-off HVAC returns and supply registers, with the system off during sanding
- Covered light fixtures, built-ins and any new countertop surfaces
Plan to sleep elsewhere for at least three nights with water-based finish and a full week with oil-based. Pets, especially birds, should stay away for the longer window.
Blending New Boards With Old Floors
Removing a wall or expanding a doorway leaves a gap in the flooring, and the patch is where amateur work shows. Weaving new boards into the existing field, rather than butting them in a straight line, is what makes the repair disappear after sanding.
Species, cut and board width all need to match. Quartersawn white oak next to plainsawn white oak will stain differently no matter how carefully it is sanded, and a 2 1/4-inch strip floor cannot be patched with 3 1/4-inch stock without an obvious seam.
New wood also absorbs stain faster than 60-year-old wood that has oxidized. Ask for sample boards stained alongside a sanded section of the original floor before the whole room gets committed to a color. Experienced builders like Kanna Construction will always prepare these sample boards on site so you can evaluate the exact tone before full application.
Color and Sheen Decisions That Age Well
Satin sheen hides scratches, footprints and dust far better than semi-gloss, which is why it has been the default on most remodeling projects for the past decade. Matte reads modern but shows wear patterns in sunlight.
On color, very dark stains such as ebony and true gray show every crumb and need more frequent recoating. Mid-tone browns, natural oak and light white-oak looks tend to stay current longer and work with more cabinet and wall colors.
One design note worth borrowing from open-concept home remodeling ideas: running the same floor and finish continuously through kitchen, hall and living areas makes a modest footprint feel noticeably larger. The National Wood Flooring Association publishes installation and sanding standards you can reference when comparing bids from different companies.
A Realistic Refinishing Timeline
For 1,000 square feet with water-based finish, most crews need four to five days: one day for sanding and screening, one day for stain if used, two days for three coats, and a final day of cure before light foot traffic. Oil-based adds three to four days.
Furniture should stay off the floor for a full week, and area rugs for two to four weeks so the finish can release solvent without trapping moisture. Rushing that window is the single most common cause of cloudy spots and peeling.
Talk Through Your Flooring Plan Before Demolition Starts
Getting the sanding schedule, finish type and patching plan settled early keeps a project on budget and your floors out of the repair line. Contact Kanna Construction & Remodeling to guarantee these choices are integrated smoothly into your overarching renovation schedule from demolition to the final coat of finish.
