Polished screed floor cost typically runs $8-$20 per sq. ft. for a professionally installed cement-based floor, with an average around $13 per sq. ft. The final price depends on floor area, screed thickness, surface condition, polishing level, and whether the job needs a new screed, repairs, or removal of an existing floor.
Because “polished screed” is not a standard U.S. contractor term, estimates may describe the work as polished concrete, a polished cementitious overlay, or a ground and sealed screed. The scope and finish should be confirmed before comparing quotes.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Polished screed floor | $8/sq. ft. | $13/sq. ft. | $20/sq. ft. | Typical grinding, polishing, and sealer on a sound floor |
| Small-room project | $1,200 | $2,600 | $5,000 | About 150-250 sq. ft.; minimum charges affect small jobs |
| New screed installation | $5/sq. ft. | $9/sq. ft. | $15/sq. ft. | Material and placement, before premium polishing |
| Repairs and preparation | $1/sq. ft. | $3/sq. ft. | $7/sq. ft. | Crack filling, adhesive removal, or localized leveling |
What polished screed flooring costs per square foot
For an existing, structurally sound cement floor, grinding and polishing commonly costs $8-$15 per sq. ft. A more complete project that includes deeper surface preparation, patching, densifier, multiple polishing passes, and sealer is often $12-$20 per sq. ft. A decorative aggregate exposure or high-gloss finish can push the total above $20 per sq. ft.
Installing a new cementitious screed and then polishing it is a different scope. Basic screed placement may cost $5-$15 per sq. ft., while the later grinding and polishing can add another $6-$15 per sq. ft. Combined project pricing can therefore reach $11-$30 per sq. ft., excluding major demolition or subfloor reconstruction.
A practical starting budget is $13 per sq. ft. for a standard, professionally polished floor over a suitable base. At that rate, a 500-sq.-ft. room would cost about $6,500 before unusual repairs, furnishings removal, or access charges.
Assumptions: U.S. mid-market labor, normal access, a stable concrete or cementitious base, and a clear, standard sealer rather than a specialty coating.
How grinding, screed, and sealer appear on the quote
Polishing quotes may combine several tasks into one square-foot rate, so the estimate should identify what the contractor includes. New screed, extensive floor preparation, and decorative finishing can be priced separately. The following ranges are typical planning figures, not fixed national rates.
| Quote item | Typical price | What changes the charge | Common billing unit |
|---|---|---|---|
| Surface grinding and polishing | $6-$15 | Number of passes, aggregate exposure, edge work | Per sq. ft. |
| Screed material and placement | $5-$15 | Mix type, thickness, reinforcement, site access | Per sq. ft. |
| Crack or surface repairs | $1-$7 | Repair depth, crack length, patching volume | Per sq. ft. or repair |
| Densifier and sealer | $0.75-$3 | Product, number of applications, sheen | Per sq. ft. |
| Old-floor removal and disposal | $2-$8 | Adhesive, tile or coating thickness, haul distance | Per sq. ft. |
Labor is commonly built into the installed rate, but some contractors quote crew time separately at about $50-$100 per worker-hour. A 600-sq.-ft. straightforward polish might require a small crew for two to four working days; adding screed placement, curing time, or extensive repairs lengthens the schedule.
Check whether the quoted square-foot price includes grinding edges, crack filling, densifier, sealer, and cleanup. An apparently lower bid may omit one or more of these tasks or assume the floor is already clean, level, and ready to polish.
Why thickness and aggregate exposure change the floor price
The floor’s condition and the specified finish can change the quote more than the room’s intended use. For example, a shallow grind that leaves most aggregate covered generally takes fewer passes than a finish exposing medium or large stone. The contractor should identify the expected exposure level and sheen in writing, ideally with a sample area.
- Screed thickness: A typical bonded leveling layer may be about 1/4-1 inch, while thicker or unbonded assemblies can require more material and additional installation steps. Thickness, substrate, and product requirements determine whether reinforcement or edge details are needed.
- Floor area: Projects under roughly 300 sq. ft. may carry a minimum charge or higher per-square-foot rate because mobilization and machine setup are spread over less area. A 1,000-sq.-ft. open floor often has a lower unit price than several small rooms totaling the same size.
- Surface variation: A floor with dips greater than about 1/4 inch over 10 feet may need leveling before a consistent polish can be achieved. High spots, glue residue, paint, and previous coatings add grinding or removal time.
- Finish specification: A standard satin finish is generally less expensive than high gloss, extensive aggregate exposure, colored stain, or a decorative border. Extra polishing stages add labor and may require more consumables.
Moisture is another important condition. If the slab has elevated moisture or a history of water intrusion, testing and a compatible moisture-control system may be needed before an overlay or sealer is installed. Those products can add several dollars per sq. ft., and the correct remedy depends on test results and the floor system.
Ask the estimator to state thickness, aggregate exposure, gloss level, and repair allowances. These specifications make bids easier to compare and reduce the chance that a low quote reflects a simpler finish than expected.
How long polishing crews work on a typical room
For an open 400-800-sq.-ft. area in good condition, grinding and polishing commonly takes two to four workdays. A compact crew may include two or three workers, with time divided among initial grinding, crack repairs, polishing passes, densifier application, and sealing. Corners and narrow rooms often take longer per square foot than open spaces.
A new screed installation adds placement and curing time. Depending on product, thickness, temperature, humidity, and ventilation, the screed may need days or longer before polishing can begin. The contractor should give a project schedule based on the actual material and manufacturer requirements rather than promising immediate access.
Labor costs rise when the crew must work around occupied rooms, stairs, limited power, tight doorways, or restricted delivery hours. Moving furniture and protecting adjacent spaces may be billed separately, often as a flat charge or at an hourly rate. Before work begins, confirm who handles furniture, baseboards, door trimming, and dust control.
Request separate start-to-finish timing for screed placement, curing, polishing, and sealer access. The floor may look finished before the sealer has reached the point at which normal traffic or furniture placement is allowed.
Regional price differences for cement floors
Labor availability and commercial construction demand influence polished-floor pricing. As a broad comparison, urban markets on the West Coast and in the Northeast can run about 10%-25% above a mid-market estimate, while some rural areas in the South or Midwest may run 5%-15% below it. These differences are not guaranteed; travel distance, local trade availability, and project size can outweigh a regional average.
For a standard scope priced at $13 per sq. ft. in a mid-market area, a comparable quote might be around $14.30-$16.25 per sq. ft. in a higher-cost city, or $11.05-$12.35 per sq. ft. in a lower-cost rural market. The comparison assumes the same preparation, finish, materials, and access.
Climate also affects project planning rather than automatically setting the price. Humidity, cold weather, and ventilation can influence screed curing and sealer application. A contractor may schedule extra time or specify a different compatible product where the work area cannot maintain recommended conditions.
Compare local bids using the same written finish and prep requirements, not just the same floor area. A regional discount is not meaningful if it excludes moisture testing, repairs, or disposal that another estimate includes.
Three polished screed floor quotes for real project sizes
The examples below show how scope affects a plausible total. They assume ordinary residential or light-commercial access and do not include sales tax, major structural work, or furniture storage. Actual contractor minimums and local rates can shift the totals.
| Project | Scope and rate | Estimated total | Why it costs this much |
|---|---|---|---|
| Small kitchen, 180 sq. ft. | Standard polish at $14/sq. ft.; $450 minimum mobilization allowance | $2,520-$2,970 | Small area, edge work, and setup are a large share of the bill |
| Open living area, 600 sq. ft. | Polish at $12/sq. ft.; $900 for patching and coating removal | $8,100 | Moderate prep with a standard satin finish |
| New 900-sq.-ft. floor | Screed at $9/sq. ft. plus polish at $12/sq. ft. | $18,900 | New leveling layer followed by grinding and sealing |
For the 600-sq.-ft. example, the base polishing charge is $7,200. The additional $900 covers specified preparation, making the effective total about $13.50 per sq. ft. In the new-floor example, the combined rate is about $21 per sq. ft.; this assumes the existing base does not need structural correction.
Use the line items to test whether a quote matches the project’s actual condition. A clean slab may not need the $900 preparation allowance, while a floor with stubborn adhesive or extensive cracks could require more.
Polished screed versus a concrete overlay or floor covering
When an existing slab is suitable, polishing it is often less expensive than installing a new layer. A cementitious overlay may be useful when the surface is stained, uneven, or visually inconsistent, but overlay installation and polishing together can cost about $12-$30 per sq. ft. depending on thickness and finish. A very thin decorative microtopping may be priced higher because application and detailing are specialized.
Tile, luxury vinyl plank, and engineered wood offer different performance and appearance. Installed vinyl plank commonly falls around $5-$12 per sq. ft., while standard tile often costs about $8-$20 per sq. ft. These alternatives can require underlayment, transitions, and demolition, so the floor-covering rate alone is not a full comparison. Polished floors avoid recurring grout cleaning but can feel hard and cold underfoot.
Repairing and repolishing an existing cement floor can be less costly than replacing it if damage is limited to superficial cracks or dull sealer. A contractor may charge $2-$7 per sq. ft. for localized repair and recoating, though deep cracks, movement, or moisture problems need diagnosis before a cosmetic fix is chosen.
Compare full installed scopes, including removal, subfloor preparation, transitions, and finish protection. A lower-cost covering can become more expensive if old flooring must be removed or the substrate needs substantial leveling.
Ways to reduce the polishing bill without cutting finish quality
Preparing the space can control labor. Clear furniture and loose items before the crew arrives if the contractor allows it, and confirm whether the price changes when the room is ready for immediate work. Avoid scheduling several small, separate visits when adjacent spaces can be completed together; one mobilization across a larger area may lower the effective rate.
Keep the scope focused on the finish that will actually be used. A medium-grit, satin polish may be adequate for many homes, while a mirror-like sheen or decorative aggregate exposure adds passes and labor. Request a sample panel before selecting a premium finish so the appearance can be evaluated against its added price.
Have at least three contractors inspect the same floor and provide written, itemized estimates. Ask each to price the same square footage, repair allowance, sealer, edge work, and finish level. If estimates differ sharply, check whether one assumes no adhesive removal, no crack repair, or a different aggregate exposure.
Schedule nonurgent work when local contractors have more availability, but avoid choosing a date solely for a discount if the room’s temperature, humidity, or access conditions are unsuitable. Do not skip moisture evaluation or necessary repairs to reduce the initial bill; failure of a coating or overlay can cost more to correct.
The most reliable savings usually come from combining areas, limiting unnecessary finish upgrades, and comparing identical scopes. A quote that clearly separates polishing from repairs makes it easier to remove optional work without sacrificing the floor’s essential preparation.
