What's under your floor?
Ontario began as the Model Colony in 1882, so a street can mix a 1920s bungalow, a 1980s tract house and a 2020s slab-built home within a few miles. The age of the house is the best first clue to what is under the carpet. The table is general; the actual floor is checked on site.
| Home built | Likely situation | Typical issue | Refinish or replace? |
|---|---|---|---|
| Before 1950 | Wood strip floors on a raised foundation, sometimes under carpet or linoleum | Wear paths, old wax, gaps, paint with lead in older layers | Often refinish; a test for lead comes first |
| 1950 to 1979 | Wood on a raised foundation or a slab with tile, vinyl or carpet | Black adhesive or old vinyl that may need testing; mixed floors | Check what is under the covering before choosing |
| 1980 to 1999 | Tract homes, mostly slab with carpet, tile or a builder floor | Tile or carpet to remove, concrete moisture to test | Mostly new engineered over a tested slab |
| 2000 and later | Ontario Ranch and other newer neighborhoods, concrete slabs, HOAs | New slabs release moisture, builder carpet, condo sound rules | New floor; test the slab and check HOA rules |
Median housing age in the city is around 1981, but it is a split distribution: roughly half of the housing was built before 1980, and more than one in five homes dates from 2000 or later. Central Ontario has thousands of units built before 1950, while Ontario Ranch, annexed in 1999, keeps adding new homes.
No one sourced figure says how many Ontario homes sit on slabs and how many on raised foundations, so the table speaks only of what is typical for each era. A floor vent or a removed threshold shows the real thickness and the subfloor in a few minutes.
The climate adds its own rhythm. Ontario's July high averages about 94°F and January's about 68°F, with 11.6 inches of rain a year, almost all in winter. Santa Ana winds in fall and winter pull the humidity down, and wood shrinks as indoor air dries, which is why seasonal gaps are normal and a humidifier or a stable thermostat helps.
Santa Ana season checklist
- Gaps between boards open in the dry months
- Normal wood movement; fill only after the dry season, ask the maker for the indoor humidity range
- Floor cups after a wet winter or a leak
- Find and stop the moisture first; sand only once the boards are flat and dry
- Gaps near a heating vent
- Direct hot air dries boards faster; check the vent and the humidity
- Brand-new slab home
- New concrete holds more water; test the slab before wood goes down
See a stain on a species before choosing
Choose a wood, a stain, a sheen, a plank width and a layout. The preview is an approximation on a screen; a sample brushed on your own boards is the real test.
On-screen approximation; ask for stain samples on your own floor.
How much sanding can your floor still take?
A rule of thumb, not a guarantee. Look at the edge of a board at a floor register or under a removed threshold, or check the wear layer listed on the flooring box.
| Floor | Typical sandings left |
|---|---|
| Engineered, 2 mm wear layer | Usually a screen and recoat only, perhaps one light sanding |
| Engineered, 3 mm | Often one, sometimes two light sandings |
| Engineered, 4 mm | Often two to three |
| Engineered, 6 mm | Often several |
| Solid, 3/4 in. boards | Usually several over the floor's life |
—
3/4 in. solid boards usually have about 6 mm above the tongue.
Based on about 1/32 in. (0.8 mm) removed in each full sanding, with some wood left above the tongue or the glue line. Every floor is different, and the flooring maker's limits come first.
Four ways a hardwood floor goes down, layer by layer
-
Solid, nail-down over wood
- Joists
- Plywood subfloor
- Paper or felt
- Solid boards
- Wall gap and baseboard
Fits Fits a raised-foundation house or an upstairs room where the subfloor is wood; the boards can be sanded and refinished several times.
Typically $10–$15 per sq ft about $3,000–$4,500 for 300 sq ft, installed
-
Engineered, glued to a slab
- Concrete slab
- Moisture barrier
- Adhesive
- Engineered plank
- Baseboard and wall gap
Fits Fits a slab-on-grade house such as most Ontario Ranch homes, once a moisture test passes the manufacturer's limits.
Typically $8–$12 per sq ft about $3,000–$4,800 for 300 sq ft, installed
-
Engineered, floating over a slab
- Concrete slab
- Underlayment
- Locked planks
- Expansion gap
- Baseboard
Fits Fits a condo or a slab that is flat enough but not suited to adhesive, with an underlayment that also helps with sound.
Typically $8–$12 per sq ft about $2,700–$4,200 for 300 sq ft, installed
-
Engineered, wide-plank white oak
- Backer
- Core
- Wear layer
- Finish
Fits Fits a living area where a wide-plank look matters and a thicker wear layer leaves room for a later refinish.
Typically $12–$18 per sq ft about $4,200–$6,600 for 300 sq ft, installed
Solid, engineered or a refinish of what you have?
Every flooring ad argues for its own product, so here is the side-by-side as plain trade-offs. Cost bands are Ontario labor and material for a typical room, from the calculator on this page; the rest is general product behavior, and the manufacturer's instructions decide.
| Option | Typical cost | Over a concrete slab | Can it be sanded again? | Where it tends to go wrong |
|---|---|---|---|---|
| Engineered, prefinished standard plank | $8–$12 per sq ft | Yes, glued or floating after a moisture test | Depends on the wear layer the maker states | Skipped slab test, uneven slab, thin wear layer |
| Engineered, wide-plank white oak | $12–$18 per sq ft | Yes, usually glued | Often once or more with a thick wear layer | Wide boards show a flat-floor error and seasonal movement |
| Solid, prefinished | $10–$15 per sq ft | Only over a plywood subfloor on top of the slab | Usually several times | Nailed directly to nothing, damp slab, wrong gap at walls |
| Solid, sanded and finished in place | $11–$17 per sq ft | Only over a plywood subfloor on top of the slab | Usually several times | Rushed drying between coats, uneven stain |
| Herringbone or chevron | $14–$22 per sq ft | Engineered versions glue to a tested slab | Per the product | Layout set out off-square, extra waste |
| Refinish what you have | $4–$6 per sq ft | Not applicable | That is the point; one sanding is removed | Wax or polish under the finish, thin boards |
Cost bands are market estimates, not quotes. No claim of strength or lifespan is made for any row; compare the wear layer, the written moisture limits and the finish instead.
When can you walk on it, and when do furniture and pets come back?
A typical order of events. The finish maker's times for the product used, the room's temperature and humidity, and the installer set the real schedule; keep people and pets off until they say so, and ventilate.

A short gap between leases: a recoat where the finish is intact, a sanding where the wood is scratched.
-
Restaurants and shops
Heavy foot traffic, a finish chosen for wear and work planned around closing days.
-
Offices and showrooms
Zones done after hours or on weekends, then a regular recoat to keep the finish up.
-
Private studios
Maple floors for dance, yoga or fitness, with sport-style finishes and painted lines.
A sand-and-stain refinish in six steps
Look, measure, testThe floor is measured wall to wall, checked for wax, deep stains, loose boards and nail heads, and older paint is tested for lead before any sanding.
Clear and protectFurniture comes out, vents and doorways are sealed with plastic, and the sander is connected to a vacuum that captures most of the dust.
Sand in passesA drum sander works through coarser and finer grits with the grain, an edger reaches the walls, and a final screen smooths the surface.
Repair and cleanGaps and nail holes are filled, a few boards may be replaced, and the room is vacuumed and wiped until the surface is clean.
Stain and finishStain, if any, goes on first. Coats of finish follow with light sanding between them, as the finish maker's data sheet describes.
Dry, then move backPeople, furniture, rugs and pets return in that order, only after the times on the data sheet for that day's temperature and humidity.
Before you sign: eight questions for any hardwood floor bid
- What is included: furniture moving, baseboards and shoe molding, subfloor repairs, a moisture test, stain samples?
- For a concrete slab: how was moisture tested (ASTM F2170 or F1869), what were the readings, and what are the manufacturer's written limits?
- Species, grade, plank width and, for engineered, the wear layer thickness in the product's own terms?
- For a refinish: how many coats, which finish type, and what sheen, in writing?
- Is the sander connected to a vacuum, and what is cleaned afterward?
- Which floors are older than 1978, and how is paint tested for lead before sanding?
- What does any warranty cover (finish wear, moisture, workmanship), for how long, and what does it exclude?
- When may people walk on the floor, put rugs down and move furniture back, per the finish maker's data sheet?
Check the contractor's license at cslb.ca.gov before signing; work above $1,000 requires one.
Hardwood floor questions, answered
How much does hardwood flooring cost in Ontario, CA?
In 2026 a typical Ontario range is about $8–$12 per square foot installed for engineered prefinished plank, $10–$15 for solid prefinished, $12–$18 for wide-plank white oak and $14–$22 for herringbone, on a wood subfloor. A slab adds $1–$4, removing carpet $0.50–$1.50 and tile $2–$5. A 300 sq ft living room in engineered wood lands near $2,400–$3,600 before options. These are market estimates, not quotes.
How much does it cost to refinish hardwood floors here?
Typically $4–$6 per square foot for sand and refinish in the natural color, $5–$8 with stain, and $2–$4 for a screen and recoat. A 300 sq ft living room refinished in natural color falls near $1,200–$1,800 on a floor in good shape. Wear paths, pet stains and old wax add to that.
Is engineered or solid hardwood better over a concrete slab?
Engineered wood is generally the one made for slabs because its layered construction is more stable; solid wood is not glued to concrete and, if used, goes over a plywood subfloor laid on the slab. Either way a moisture test comes first, and the flooring maker's written limits control.
How do I know whether my floor can be sanded again?
Solid hardwood can usually be sanded and refinished several times. Engineered flooring depends on the thickness of its wear layer, which the maker states, and a floor vent or a removed threshold shows the board. A screen and recoat refreshes the finish without sanding to bare wood.
Does sanding make a mess?
Sanding makes fine dust. Many refinishers connect the sander to a vacuum that captures most of it, seal doorways and vents with plastic and clean afterward; some fine dust still settles. The guide on this site explains what the word 'dustless' does and does not mean.
What are the gaps between my floorboards in winter?
Wood shrinks as indoor air dries, and Ontario's Santa Ana winds can drop humidity sharply in fall and winter. Seasonal gaps are common and often close again; boards that cup or buckle point to moisture instead.
Can I put hardwood in an Ontario Ranch condo or HOA home?
Often yes, but many associations require an acoustic underlayment with a stated sound rating and written approval first. The CC&Rs decide, and a lab rating is not a field test.
How long does a refinish take?
A screen and recoat is often a day or two. A full sand and finish takes longer, usually several days with drying time, and the finish maker's data sheet sets when people, rugs and furniture can return.
Do old floors contain lead paint or asbestos?
In homes built before 1978, paint on floors or trim can contain lead, and old vinyl tile or black adhesive under an old floor can contain asbestos. Both are tested before sanding or removal.
Are rentals, restaurants and studios covered too?
Yes. The Business & rentals pages cover rental turnover floors, restaurant and retail floors, private dance, yoga and fitness studios and commercial refinishing, with a separate business path in the calculator.
