Polished concrete cost calculator: a planning range for your square footage
This calculator estimates what polishing an existing concrete slab costs in 2026 from square footage, a sheen tier, a slab-condition tier and optional add-ons. It is anchored to Angi's $3 to $12 per square foot range and HomeGuide's gloss tiers, with a premium for small areas. The output is a range for comparing proposals.

Cost benchmarks behind the calculator
$3–$12 per sq ft
Angi prices polishing an existing concrete floor at $3 to $12 per square foot
Angi's polishing cost guide describes polishing existing floors; removal of coverings, repairs, design effects and new slab construction are separate scope items. It is the benchmark behind this site's calculator.
Angi cost to polish concrete floors (2026)$3–$6 up to $6–$15
Matte polish $3–$6, low sheen $4–$8, medium gloss $5–$10, high gloss $6–$15 per sq ft
Each step up in gloss adds grinding and polishing steps; HomeGuide's high-gloss range is roughly double matte. Decide on sheen before collecting bids so quotes are comparable.
HomeGuide polished concrete floor cost guide (2026)$8.26–$9.77 per sq ft
Homewyse estimates $8.26 to $9.77 per sq ft to polish a concrete floor
Homewyse's September 2026 basis includes sweeping, washing, crack repair, a 3-pass grinding process, densification and a 2-pass final polish under favorable site conditions.
Homewyse cost to polish concrete (2026)$8–$15+ vs $3–$6
Jobs under 1,000 sq ft cost $8–$15+ per sq ft; over 5,000 sq ft can drop to $3–$6
HomeGuide notes mobilization and equipment setup make small residential floors far more expensive per square foot than warehouses or big-box stores.
HomeGuide polished concrete floor cost guide (2026)Every published polishing range is wide because the choices inside it are large. Angi's guide runs $3–$12 per sq ft; HomeGuide's gloss tiers run from matte at $3 to $6 to high gloss at $6 to $15, and Angi's July 2026 flooring guide runs from $2–$6/square foot for matte through $3–$8/square foot for semigloss to $8–$15/square foot for high gloss. The calculator's job is to narrow that to the combination you are considering: a 900-square-foot basement at Level 2 with a guard is a different number from a 1,800-square-foot living area at Level 3 with dye.
The base rate is a mid-gloss, mid-condition national figure. The sheen tier moves it up or down with HomeGuide's ratios; the condition tier adds for coverings, repairs and access; the add-ons are flat lines from HomeGuide and HomeAdvisor. The assumptions under the result say what is included, and the polishing page explains each driver.
How is the base rate set, and why is it not the cheapest number you have seen?
The base is $7 per square foot, the middle of Angi's range and inside HomeGuide's medium-gloss tier of $5 to $10. It reflects a sound slab with light coverings, a Level 3 finish with Class A or B exposure, densifier, edges and standard dust control. Homewyse's contractor-scope figure of $8.26–$9.77 per sq ft for a three-pass grind, densify and two-pass polish lands close to it.
The cheapest numbers you have seen, $2 or $3 per square foot, are large commercial floors: HomeGuide's $8–$15+ vs $3–$6 contrast shows why a warehouse rate does not apply to a house. The calculator applies a premium for areas under 1,000 square feet for the same reason, since mobilizing a planetary grinder and extractor costs the same for a basement as for a store.
What do the sheen and condition tiers change?
Sheen is passes. HomeAdvisor prices each additional grinding pass for a higher shine at $3–$5 per sq ft, and HomeGuide's tiers reflect it: matte roughly two-thirds of medium gloss, high gloss roughly one and a half times. The calculator's three sheen tiers use those ratios. A honed Level 2 floor is not a lesser floor; it is fewer passes, less glare and easier upkeep, which many homes prefer.
Condition is removal, repairs and access. A bare, sound slab is priced below base; a slab with glued carpet, a few cracks and normal access is base; a slab with an old coating, many repairs, a thin section or basement stairs is above it. HomeGuide's +10% to 30% for hard-to-reach basements sits inside the top tier. If you do not know what is under the covering, choose the middle tier and expect the assessment to move it.
| Tier | What it assumes | Basis |
|---|---|---|
| Matte / honed (Level 1–2) | Fewer passes, low glare, densified | HomeGuide $3–$6 |
| Medium gloss (Level 3) | Standard residential polish | HomeGuide $5–$10; Angi mid-range |
| High gloss (Level 4) | Extra fine passes, burnishing, shows scuffs | HomeGuide $6–$15; Angi $8–$15 |
| Bare, sound slab | No removal, few repairs, ground-level access | Below base |
| Typical renovation slab | Light covering removal, some cracks, normal access | Base |
| Heavy prep or basement | Coating removal, many repairs, stairs and obstructions | HomeGuide +10–30% and removal passes |
What do the add-ons cover, and what is left out?
Dye adds a single color inside the polish at HomeGuide's $1–$3 dye; $3–$5 stain, modeled as a flat line for a typical room. Stain guard adds the penetrating protection HomeGuide prices at $1–$3 every 2–5 yrs. Crack repair covers cleaning, filling and grinding flush a handful of cracks. Coating removal covers grinding off a thin sealer or paint; a thick epoxy can cost more. A moisture test is a small line worth paying for before any dye or guard.
Left out: leveling by overlay or jacking, which HomeGuide prices separately at $3–$12 per sq ft; multi-color or patterned staining; removal of tile with thinset; disposal of large volumes of debris; and any structural repair. Those belong on the grinding and leveling page and the staining page and should appear as their own lines in a proposal.
How should you use the result when proposals arrive?
Compare the proposal's total and its per-square-foot rate to the calculator's range at the same sheen and condition. Inside the range: compare the specification. Below the range: look for what is missing, usually removal, edges, the mock-up or closeout readings. Above the range: look for what is added, usually an overlay, a higher level or heavy removal, and ask whether it is needed. The comparison pages help if a proposal suggests a different finish altogether.
The calculator's day estimate uses HomeGuide's 2–4 days for residential work. A proposal that promises a Level 3 floor on 1,500 square feet in one day is skipping passes; one that schedules two weeks for the same floor may be fitting you between commercial jobs, which is normal, but ask.

Cost calculator questions
Why does the per-square-foot price go up when I enter a smaller floor?
Because mobilization is fixed. HomeGuide's data shows floors under 1,000 square feet at $8 to $15 or more per square foot while floors over 5,000 drop to $3 to $6, since moving a planetary grinder, extractor and crew costs the same for any size. The calculator applies a small-area premium so a 300-square-foot room does not produce an unrealistically low total.
Does the calculator include removing tile or carpet?
Light covering removal, such as glued carpet or a thin sealer, is inside the typical and heavy condition tiers, and thin coating removal is an add-on. Tile with thinset, thick epoxy and multiple layers are not modeled because their cost depends on bond and thickness. Ask for a per-pass removal rate in the proposal for those.
Should I pick medium or high gloss?
Pick by room and light, then check the price difference. High gloss costs roughly one and a half times medium in HomeGuide's tiers and shows scuffs and dust more. Most homes are happier at Level 2 or 3. If you want the mirror look, budget for it and for a slip-resistant guard at entries, and sample both levels before deciding.
Can I use the calculator for a new slab?
Roughly. A new slab placed for polishing usually needs fewer passes and no removal, so choose the bare condition tier. Angi's guide prices a new slab for polishing at $4–$8/square foot before the concrete itself. If the slab is being poured, tell the builder it will be polished so the mix, finishing and curing suit it.
Why is the dye add-on a flat number?
For simplicity at typical room sizes. HomeGuide prices dye at $1 to $3 per square foot, and the flat figure reflects a single color on about 800 square feet. For a much larger or smaller floor, scale it, and for two colors or patterns use the staining page's ranges. A proposal should state dye per square foot and per color.
How does the day estimate work?
It applies HomeGuide's two-to-four-day guidance for residential floors up to 2,000 square feet as a rate per 100 square feet, with a floor of about two days for any job. Repairs, coating removal, dye and a separate mock-up day extend it. Proposals should schedule the mock-up before the full grind.
What if my proposal is half the calculator's number?
Read the scope. Half the number usually means fewer passes than the level requires, edges excluded, no mock-up, no densifier named or no closeout readings. Occasionally it means a large commercial pro fitting a small job between contracts at a low rate, which is a genuine bargain. Ask the pro to walk through the specification line by line before deciding which it is.

Service guideConcrete PolishingConcrete polishing grinds an existing slab with progressively finer diamond abrasives, hardens it with a densifier and refines it to a specified sheen and aggregate exposure.
Service guideConcrete Staining & DyeingStaining and dyeing add color to a concrete slab by penetrating the surface rather than covering it, so the aggregate, patches and variation remain part of the look.
Service guideConcrete Grinding & LevelingGrinding uses coarse diamond tooling to remove coatings, adhesives, lips and high spots and to open a surface profile for whatever finish follows.
Service guideConcrete Sealing & ProtectionSealing and protection treatments defend a concrete floor against stains, moisture and wear, and they range from penetrating silicates and siloxanes that leave the look unchanged to film-forming acrylics, urethanes and epoxies that add gloss and a wear layer.
