Installation

Countertop install crews: size, tools, training and piece-rate pay

How stone shops staff and equip install crews: crew size, what goes on the truck, training helpers, onboarding installers and legal piece-rate pay.

, CEO, Stonify

A standard residential stone install crew is two people: a lead installer and a helper. They typically set one or two average kitchens a day, or several vanities. A third person joins for pieces over about 250 lb, island tops over about 6 feet, stair carries and large commercial jobs. A fully equipped stone install truck typically carries $5,000 to $20,000 in tools (2026 U.S. ranges, shop experience), plus a few hundred dollars a month in consumables. A new helper becomes useful in four to six weeks and can lead jobs after roughly three to six months. Installers are paid hourly, by the job, or by the square foot (piece rate). Piece rate works well if it is set from real time data, covers the non-footage work, and meets federal and state minimum wage and overtime rules every week.

How big should an install crew be?

Two people is the norm because a two-person crew with suction cups, a vacuum lifter and a cart can safely handle most residential pieces, and a third person would stand around for much of the day. The decision to add people comes from the heaviest piece and the path, not from the total square footage.

Job

Typical crew

Why

Vanity tops, small kitchens, pieces under about 150 lb

2

Two with suction cups handle it

Standard kitchen, 40 to 60 sq ft, pieces up to about 250 lb

2

With cups, cart and a vacuum lifter

Island over about 6 ft, any piece over about 250 lb

3

Weight, and a third hand under long spans and cutouts

Stairs, walk-ups, tight access

3 or more

Control on stairs matters more than strength

Waterfall islands, mitered pieces, full-height backsplash on the same day

3

Handling fragile shapes and more steps

Commercial jobs with deadlines

3 to 5

Parallel work: prep, setting, seams

For weights: 3cm granite runs about 17 to 19 lb per square foot and 3cm quartz about 14 to 16. A 10-foot, 25-1/2 inch run in 3cm granite is about 360 to 400 lb. A 4-by-10-foot island in 3cm quartz is about 560 to 640 lb. See handling, transport and lifting for crew rules by weight.

Adding a person raises labor cost on that job by about half, so some shops charge a surcharge for oversized pieces or difficult access. Bigger is not better by default. A trained two-person crew with good templates beats a disorganized three-person crew.

How many installs a crew can do in a day

Job

Typical on-site time, 2-person crew

Bathroom vanity

45 to 90 minutes

Standard kitchen, 1 seam, undermount sink

2 to 4 hours

Large kitchen, several seams, island, 4-inch splash

4 to 6 hours

Complex kitchen with full-height backsplash or waterfall

5 to 8 hours

Tear-out of an old stone top

Add 30 minutes to 2 hours

That puts a typical crew at two standard kitchens a day, or one large kitchen plus a vanity or two. Schedule by the slower jobs, not the average. A useful rule is to book to about the 75th percentile of your own install times and add 15 minutes per stop for travel buffer and setup. Crews that are booked to the average run late every week. See installation logistics for routing and scheduling.

Roles on the crew

  • Lead installer: owns the job on site. Reads the shop drawing, checks the pieces against it, confirms cabinets are level and ready, decides on any field changes, sets seams, talks to the customer, handles the walkthrough and, at many shops, collects the final payment.

  • Helper: carries, sets up and cleans up, handles shims and supports, mixes adhesives, runs the vacuum during cutting, and learns the lead's steps one at a time.

  • Third person (when used): extra hands for carrying and holding, sometimes a second installer who runs splashes and caulking while the lead seams.

Tools and the install truck

A stone install truck needs the gear to lift and set the pieces, make small field corrections, seam, and fix chips. Whether the crew also cuts cutouts or polishes edges on site changes the budget a lot.

$1,500 to $6,000

Measuring and leveling

Two tape measures, 2-ft and 4-ft levels, 6-ft straightedge, laser level, scribe, angle finder

$200 to $800

Cutting and grinding

$800 to $4,000

Polishing

Wet polisher or variable-speed grinder, diamond pad set from 50 to 3,000 grit, backer pads

$500 to $1,500

Total: roughly $5,000 to $20,000 per truck, not counting the vehicle. Consumables (blades, pads, epoxy, silicone, shims, gloves, blankets) often run $300 to $800 a month per busy crew (rule of thumb).

Two items deserve emphasis:

  • Dust control is required. Cutting, grinding or polishing stone on site falls under OSHA's construction silica standard (29 CFR 1926.1153). Its Table 1 lists accepted controls by tool. A hand-held power saw needs an integrated water feed to the blade, plus a respirator indoors and for more than 4 hours a shift outdoors. A hand-held grinder needs either an integrated water feed (an option Table 1 allows outdoors only) or a commercially available shroud with a dust collector that moves at least 25 cubic feet per minute per inch of wheel diameter through a filter of 99% or better efficiency, with a respirator for shroud work indoors over 4 hours a shift. If you don't follow Table 1 fully, you must assess exposure and keep it under the limit. The employer also needs a written exposure control plan, a competent person on site and trained workers. In California, high-exposure work on artificial stone must be done wet (Title 8 section 5204 and SB 20). Cal/OSHA's updated draft emergency rule of October 22, 2026, would also ban installing artificial stone with about 1% or more crystalline silica starting 360 days after the rule takes effect; as of November 5, 2026, it is a draft and no adoption vote is on a posted agenda. Engineered quartz typically contains about 90% or more crystalline silica, the most of common countertop materials, so field cuts in quartz carry the most risk. See OSHA silica compliance.

  • Buy name-brand lifting gear. A cheap suction cup that lets go costs the slab, and sometimes a foot.

Keeping the truck stocked

Crews lose time when they arrive without the right color of epoxy or the right sink clips. A few habits fix most of it:

  1. Zone the van. Heavy tools behind the bulkhead, consumables in labeled bins on one side, hardware and protection on the other, lifting gear and carts at the rear doors.

  2. Set a minimum count per bin and keep a restock list in the van. Silicone, for example: at least two tubes each of clear, white and the week's common colors.

  3. Do a weekly van walk, ten minutes on Friday afternoon or Monday morning, to restock from a dedicated install shelf in the shop.

  4. Match the load to the job. A job with a mitered island or a full-height backsplash needs extra seam setters, bracing and hands. Check the week's jobs before loading.

Training a helper

New helpers usually come from general labor, landscaping, tile or moving work. What they need to learn is less about strength than about how stone fails and how the crew works together. A workable progression:

Weeks

Focus

Helper can do alone by the end

1

Tool names, PPE, silica hazards, truck layout

Load and unload tools, set up dust control

2

Carrying on edge, suction cups, calls and signals, wrapping and loading

Take one end of a carry safely

3

Leveling and shimming cabinets

Check level and set shims under the lead's eye

4

Assisting cutouts and field cuts with dust control

Run the vacuum and water, support pieces

5

Mixing and tinting epoxy, cleaning seams

Mix epoxy to the right ratio and color on scrap

6

Silicone, sink clips, caulk joints

Caulk joints cleanly, install sink clips

7 to 8

Full installs with the lead watching

Most steps of a standard kitchen

A few rules keep training cheap: no epoxy on a customer's seam until the helper has done several good practice seams on scrap; no grinder work until the helper knows guard position, wheel inspection and kickback; and every lift called by one person.

Most helpers are useful in four to six weeks. Most can lead a standard kitchen after three to six months of full-time work, depending on the job mix.

Onboarding an experienced installer

An installer hired from another shop brings skill and also habits. Onboarding is about teaching your standards, not the trade.

  • First week: safety orientation and silica training before any dust-generating task, a ride-along on two or three installs, then a defined piece of work on a third.

  • Written standards: load-out checklist, arrival checklist, seam procedure, sink procedure, completion checklist with required photos.

  • Competency levels: for example, level 1 (supervised) for standard seams and sink installs on solid colors; level 2 (independent) for most kitchens; level 3 (senior sign-off) for veined seams, mitered and waterfall pieces, multi-piece islands and outdoor work.

  • 30-60-90 day check-ins: an informal talk at 30 days, a full observed job at 60, and a clear decision at 90: cleared, cleared with exceptions, or extended.

As a rule of thumb, plan on 60 to 90 days before an experienced installer works your way without oversight. Keep training records, including silica training, with your safety records.

How installers are paid

Shops use four main models, often mixed.

Hourly

Pay by the hour, overtime at 1.5x over 40 hours

New helpers, shops with very mixed jobs

Install crews, whose time depends on site conditions more than footage

Needs a clear list of what counts as a standard job

For context, the U.S. Bureau of Labor Statistics puts median pay for tile and stone setters, the federal category closest to countertop installers, at $55,690 a year in May 2025, about $26.77 an hour for a 2,080-hour year. BLS projects employment in the occupation to grow 10% from 2025 to 2035. Pay is often higher in high-cost metros and for experienced lead installers.

What piece rates look like

We found no published survey of install piece rates, and figures quoted online vary by a factor of three, usually because they describe different things. As typical 2026 U.S. ranges from shop practice (not a benchmark):

  • Employee crews: roughly $3 to $6 per square foot installed, split across the crew, with the shop providing the truck, tools and materials.

  • Subcontract install crews that bring their own truck, tools, insurance and helper: roughly $6 to $15 per square foot, or about $300 to $700 per standard kitchen.

Sanity-check a rate against hours. Two 50-square-foot kitchens a day is 100 square feet. At $5 per square foot, the crew earns $500, or about $31 an hour each over an 8-hour day, somewhat above the BLS median of about $26.77. At $12 per square foot the same day is about $75 an hour each, which only makes sense if the crew pays for its own truck, tools and insurance.

Square footage alone underpays some work, so most piece-rate schemes pay separately for:

  • Sink and cooktop cutouts made on site

  • Full-height backsplash and extra splashes

  • Field seams and seam polishing

  • Tear-out of the old top and haul-away

  • Stairs, walk-ups and long carries

  • Return trips caused by the site not being ready

  • A minimum per job, so a small vanity is worth the drive

Many shops pay install crews per job type rather than per square foot for this reason: a 30-square-foot kitchen with two seams, a sink and a third-floor walk-up takes longer than a 60-square-foot ranch kitchen with no seams.

Setting a rate

  1. Track time first. For four to six weeks, record hours and square footage on every install while paying the current way. Calculate what each person would have earned under the proposed rate.

  2. Set the rate so a normal week pays a fair hourly equivalent, with a steady crew earning more than on hourly pay and a slow week still above minimum wage.

  3. Write down the add-ons, the minimum per job and the rules for rework before the first paycheck.

  4. Add a floor for new hires, for example the higher of piece earnings or a set hourly rate for the first 90 days.

  5. Review rates yearly. Private construction wages rose 3.0% in the 12 months to September 2026 (BLS Employment Cost Index), so a rate frozen for five years is a pay cut.

Piece rate and the law

Piece rate is legal for employees, but it does not replace wage and hour rules. Under the federal Fair Labor Standards Act (FLSA):

  • Minimum wage every week. Total piece earnings divided by total hours worked must be at least the federal minimum wage ($7.25 an hour) or the higher state or local minimum. If not, the employer makes up the difference. Hours include drive time between jobs during the workday, waiting at a site that is not ready, required shop meetings and short rest breaks (about 5 to 20 minutes).

  • Overtime uses the half-time method. The regular rate is total piece earnings divided by all hours worked, including overtime hours. Piece earnings already pay straight time for every hour, so the overtime owed is an extra half of the regular rate for each hour over 40.

Worked example. An installer earns $1,200 in piece pay in a week and works 48 hours.

  • Regular rate: $1,200 / 48 = $25.00 an hour

  • Overtime premium: 8 hours x ($25.00 x 0.5) = $100

  • Total pay: $1,300

  • Records. Keep hours worked each day, units produced and the rate per unit, alongside normal payroll records. Federal rules require payroll records to be kept at least three years and time cards and piece-rate tickets at least two (29 CFR part 516).

  • State rules can be stricter. California (Labor Code 226.2), for example, requires piece-rate employees to be paid separately for rest and recovery periods and other nonproductive time. Many states restrict deductions from pay for damaged or defective work. Check your state labor department before docking pay for a remake.

Employees or subcontractors?

Many shops use subcontract install crews, especially for overflow. The label on the contract does not decide the question. The IRS looks at behavioral control, financial control (including who supplies tools and the truck) and the type of relationship. The Department of Labor applies an "economic reality" test under the FLSA; it proposed a revised version of that test in February 2026, so check the current rule. A crew that works only for you, wears your shirts, drives your truck and follows your schedule is likely to be treated as employees, whatever the paperwork says. California is stricter: under its ABC test (Labor Code 2775) a worker is an employee unless the work is outside the usual course of your business, among other conditions, and installing your countertops usually is not. A separate path for construction subcontractors requires, among other things, a written contract and a contractor license covering the work (Labor Code 2781). Misclassification can bring back taxes, penalties and gaps in workers' compensation coverage.

If you use subcontractors, get their certificate of insurance (general liability and workers' compensation), a written agreement with rates and quality standards, and a clear process for callbacks. For payments made in 2026, file Form 1099-NEC for each subcontractor you pay $2,000 or more in the year (the threshold was $600 for earlier years, per the IRS). If a subcontractor has no workers' comp, your insurer will usually add their payroll to your premium at audit. For employees, your insurer or state rating bureau assigns the class code; in NCCI states installation commonly falls under 5348. Its rate is far higher than clerical codes and varies widely by state, and putting installers in a cheaper code to save premium creates coverage gaps.

Where software helps

Crews waste time when the job information is in the office and not on the truck: the address, the gate code, the sink model, the seam location, the balance due. In Stonify, installers use a mobile app with their scheduled jobs, the job files and drawings, and a place to upload photos when they finish. The office controls how far ahead each crew, or each subcontract vendor, can see the schedule, and whether installers see invoices and the balance due so they can collect on site. Install calendars total the square footage booked per day and per installer, and the All Tasks report can show square feet installed by each installer last week, which is the number piece-rate pay is built on. Installs done by subcontract crews can be billed as vendor jobs when they are complete.

FAQ

Can one person install a stone countertop? Not safely for a normal kitchen. Solo installs are possible only for small, light pieces with powered lifting equipment, and most shops do not allow them.

Do installers do the plumbing? Usually not. Crews set the sink and may reconnect a simple drain as a courtesy where local rules allow, but most shops leave supply lines, disposals, dishwashers and gas to licensed trades.

Should install crews be paid per square foot or per job? Per job, or per square foot with generous add-ons, usually works better for installs than pure square footage, because site conditions change install time more than footage does.

How do shops handle callbacks under piece rate? Most pay nothing extra for fixing the crew's own mistakes, and pay the normal rate for callbacks caused by the shop or the customer. Write the policy down, and never let deductions take anyone below minimum wage for the week.

What should an installer's first week look like? Safety and silica training, ride-alongs on a few installs, then one defined task on a real job, with a debrief at the end of the week.
