# Post construction cleaning jobs: where builders hire, how to bid and what GCs require

> Post construction cleaning jobs come from general contractors, home builders, remodelers and property managers, and most are awarded by direct relationship or a unit-price bid, not from job boards. To win them, register on the bid platforms GCs use, bid per square foot by phase (rough, final, touch-up), carry the insurance and OSHA 10 cards sites ask for, and invoice the day each phase is done.

## Key takeaways

- Residential volume is large: privately owned housing starts ran at a seasonally adjusted annual rate of 1,221,000 in September 2026, and every finished home needs a final clean.
- Commercial GCs invite bids through platforms such as BuildingConnected, PlanHub and The Blue Book; list yourself under final cleaning and construction cleanup.
- Bid per square foot by phase from your own production rate, and quote return trips and debris hauling as separate line items.
- Sites usually require a certificate of insurance naming the GC as additional insured, workers’ compensation, and OSHA 10 cards for your crew.
- OSHA’s silica rule bars dry sweeping where it could expose workers, so bid for HEPA vacuums and wet methods.
- Expect 30 to 60 day payment terms, retainage and lien waivers on commercial jobs; price for the wait.

## Where do post construction cleaning jobs come from?

Post construction cleaning jobs come from four buyers: general contractors on commercial projects, home builders and remodelers, property managers and owners after tenant improvements or renovations, and investors flipping houses. Each buys differently, and the best source for a small company is the builder or GC who sends the same crew to every job.

| Buyer | Typical job | How they hire | Payment |
| --- | --- | --- | --- |
| Commercial general contractors | Final clean on an office, retail, school or medical build-out, 5,000 to 100,000 sq ft | Bid invitations on a platform, or a subcontract with a cleaner they already know | Pay applications, net 30 to 60, retainage |
| Production home builders | Final and touch-up cleans on every house in a subdivision | Vendor agreement with a fixed price per plan or per square foot | Net 30 after the builder’s walk |
| Custom builders and remodelers | One home at a time: kitchen, bath, addition or whole-home final clean | Referral and repeat; a phone call the week before | On completion or net 15 to 30 |
| Property managers and owners | Clean after a tenant improvement, unit renovation or restoration job | Direct quote, often with the restoration or TI contractor | Net 30 |
| Flippers and investors | Final clean before listing photos | Direct quote, fast turnaround | On completion |

The residential side is large and steady. The Census Bureau’s [New Residential Construction](https://www.census.gov/construction/nrc/current/index.html) release puts privately owned housing starts at a seasonally adjusted annual rate of 1,221,000 in September 2026, with single-family starts at 859,000. Every one of those homes gets at least one construction clean before move-in, and most production builders buy it from a contractor rather than their own staff.

New construction cleaning jobs on the commercial side are fewer but bigger, and they come with the paperwork and payment terms covered below. If you have not set up the service yet, the phases, checklist, equipment and dust rules are in [how to start a post construction cleaning business](https://broombook.com/guides/post-construction-cleaning-business). This page is about finding and winning the work.

## Where do general contractors post construction cleaning bids?

Commercial GCs send bid invitations through preconstruction platforms, and they pick who to invite from the directories on those platforms. Register on the ones your local GCs use, list final cleaning as a trade, and answer every invitation, even with a decline, so you keep getting them.

| Platform | What it is | Cost to a cleaning sub |
| --- | --- | --- |
| [BuildingConnected](https://www.buildingconnected.com/) (Autodesk) | Bid management for GCs, drawing on what it describes as a crowdsourced network of over 1.5 million construction professionals | A subcontractor profile to receive invitations; paid tiers add bid tracking |
| [PlanHub](https://www.planhub.com/) | Preconstruction bidding and plan room connecting GCs, subcontractors and suppliers; PlanHub says its directory has 400,000+ subcontractors | PlanHub lists itself as free for general contractors with basic access for subcontractors; paid plans unlock more projects |
| [The Blue Book](https://www.thebluebook.com/) | Long-running construction directory and bid network that GCs use to find and invite subcontractors | A free listing; paid profiles for visibility |
| Dodge Construction Network, ConstructConnect | Project leads and plan rooms for subs and suppliers | Paid subscriptions, priced for larger subs |
| Public bid portals | Schools, cities and agencies sometimes bid final cleaning directly for public projects | Free; see [government bids](https://broombook.com/guides/commercial-cleaning-contracts) |

### How to set up a profile that gets invitations

- **Trade and CSI section.** List “final cleaning” and “construction cleanup”. In MasterFormat, final cleaning sits in Division 01 (section 01 74 23), and some platforms let you pick it directly.
- **Service area.** Set a radius you will actually drive. Bid invitations from 90 miles away waste everyone’s time.
- **Project size.** State the square footage you can handle in a week with your current crew.
- **Proof.** Upload your certificate of insurance, a photo of your HEPA equipment and two project references.
- **Response habit.** Reply to every invitation within a day, with a bid or a polite decline. GCs stop inviting subs who go quiet.

Platforms get you invited. Relationships get you hired. Most GCs award final cleaning to a sub they have used before unless that sub is far higher in price or missed a deadline, so your first platform win is worth more than its margin.

## Rough, final and touch-up: what does a construction cleaning contract cover?

A construction cleaning contract covers one or more phases, each with its own scope and price: a rough clean during construction, a final clean after the trades finish, and a touch-up (sometimes called a sparkle clean) after punch-list repairs. On commercial jobs the GC’s specification, usually in Division 01, says what the final clean must include.

| Phase | What the GC expects | What to write into the scope |
| --- | --- | --- |
| Rough clean | Debris to the dumpster, floors vacuumed or scraped, surfaces wiped so finishes can go in | Who supplies the dumpster, how many visits, whether trades are still working |
| Final clean | Every surface detailed: glass both sides, frames, fixtures, inside cabinets, vents, floors cleaned to the finish manufacturer’s instructions, stickers and labels removed, protective film removed | Exclusions (exterior glass above the first floor, carpet extraction, floor finishing), labels you may not remove, and a single final walk |
| Touch-up | Dust from punch-list work, fingerprints, a last floor pass before turnover | Number of visits included; price for each extra trip |

### Clauses that save you money

- **Site readiness.** A return-trip fee if the site is not ready when you arrive, or trades are still generating dust.
- **Utilities.** Power, water and lighting on when you start. Without them you are hauling generators and water.
- **Debris.** The GC provides the dumpster; you bag and carry. Hauling is a separate price.
- **Damage.** A walk with the superintendent before you start, with photos of scratched glass, chipped tile and scuffed finishes you did not cause.
- **Scope growth.** Extra areas, extra visits or extra phases are a written change order, priced before the work.

The room-by-room task list for a residential final clean is in the [post construction business guide](https://broombook.com/guides/post-construction-cleaning-business); attach a version of it to every bid so there is no argument about what “clean” means.

## How do you bid post construction cleaning per square foot?

Bid per square foot by phase, built from your own production rate: the square feet one cleaner finishes per labor hour in that phase. Price the hours, add supplies, travel, overhead and margin, then divide by the area to get a unit price the GC can compare. Never start from someone else’s per-square-foot number.

### A worked bid (hypothetical numbers)

A GC asks for a final clean plus one touch-up on a 20,000 square foot office tenant improvement: open office, 14 private offices, two restrooms, a break room and a lot of glass. From past jobs, your crew finishes a commercial final clean at about 250 square feet per labor hour and a touch-up at about 1,000 square feet per labor hour. These are round numbers to show the method, not market rates.

| Line | How it is worked out | Amount |
| --- | --- | --- |
| Final clean labor | 20,000 ÷ 250 = 80 labor hours (five cleaners, two days) | 80 h |
| Touch-up labor | 20,000 ÷ 1,000 = 20 labor hours | 20 h |
| Wages and burden | 100 h × $20 × 1.20 | $2,400 |
| Supplies and equipment | HEPA bags and filters, pads, blades, lift rental for high glass | $450 |
| Travel and site time | Orientation, badging, two trips | $150 |
| Direct cost |  | $3,000 |
| Price with 20% overhead and 15% profit | $3,000 ÷ 0.65 | about $4,615 |
| Unit prices | Final: about $0.19 per sq ft; touch-up: about $0.04 per sq ft | $3,790 + $825 |

Submit the two phases as separate unit prices, plus alternates the GC can accept or drop: exterior glass, carpet extraction, floor scrub and finish, extra touch-up visits at a per-trip price, and an hourly rate for work added on site. Unit prices protect you when the area changes; GCs often add or cut space late.

### What changes the production rate

- Glass: a curtain-wall office cleans far slower than a warehouse
- Paint overspray, drywall mud and grout haze on finished surfaces
- High work that needs lifts or ladders, and the lift rental itself
- Trades still on site, so you clean the same area twice
- Prevailing wage requirements on public projects, which set your wage line for you

Time every job by phase and keep the numbers; after ten jobs your production rates will be better than any table. The [cleaning estimate template](https://broombook.com/tools/cleaning-estimate-template) gives you a clean format for the unit-price schedule, and the [commercial cleaning calculator](https://broombook.com/tools/commercial-cleaning-calculator) helps when the GC also asks for recurring janitorial after turnover.

## What do GCs require before your crew can work on site?

Before you set foot on a commercial site, the GC will ask for a certificate of insurance naming the GC (and often the owner) as additional insured, proof of workers’ compensation, a signed subcontract, a W-9, and OSHA 10 cards for your crew. Many also run a site orientation and require hard hats, safety glasses, high-visibility vests and boots.

### OSHA 10 and OSHA 30

OSHA’s [Outreach Training Program](https://www.osha.gov/training/outreach) is the source of the 10-hour and 30-hour cards GCs ask for. OSHA says the program is voluntary and that none of its courses is a certification: the 10-hour class gives workers awareness of common job-related safety and health hazards, and the 30-hour class is more appropriate for supervisors. Voluntary under federal rules does not mean optional on site: most commercial GCs write OSHA 10 into their subcontracts, and several states and cities require it on public projects. Put your lead on the 30-hour course and every cleaner on the 10-hour construction course before you bid.

### Dust rules you will be held to

Construction dust can contain crystalline silica. OSHA’s [silica standard for construction](https://www.osha.gov/laws-regs/regulations/standardnumber/1926/1926.1153) (29 CFR 1926.1153) says the employer shall not allow dry sweeping or dry brushing where it could contribute to employee exposure to respirable crystalline silica unless wet sweeping, HEPA-filtered vacuuming or other methods that minimize exposure are not feasible. Site superintendents enforce this: a crew pushing a broom through drywall dust gets sent home. Bid for HEPA vacuums, wet methods and the time they take.

### The paperwork list

- **Certificate of insurance** with the limits in the subcontract, additional insured endorsements and, often, a waiver of subrogation
- **Workers’ compensation** certificate, or in some states proof of a valid exemption; check your state
- **Subcontract agreement**, often the GC’s standard form, with its payment, insurance and indemnity terms
- **Safety data sheets** for every product you bring on site, and a site-specific safety plan if asked
- **Badges and training records** for each worker, plus the site orientation sign-in

Tell your insurance agent you do construction cleanup; it can be rated differently from house cleaning, and a GC’s required limits may be higher than you carry. Policy types and certificates are covered in the [cleaning business insurance guide](https://broombook.com/guides/cleaning-business-insurance). This is not legal or insurance advice; have someone read a subcontract before you sign one with indemnity clauses.

## How do construction cleaning contracts pay, and when?

Commercial construction cleaning contracts pay through the GC’s pay application cycle, usually 30 to 60 days after you invoice, and the GC often holds back a percentage as retainage until the project closes out. Residential builders pay faster, typically net 15 to 30 after their walk. Price the wait into your margin.

- **Pay applications.** You invoice by a monthly cutoff, the GC bills the owner, and you are paid when the GC is paid. Many subcontracts say exactly that.
- **Retainage.** A share of each payment, commonly 5% or 10%, held until closeout. Ask for it to be released when your phase is accepted, not at the end of a 12-month project.
- **Lien waivers.** You sign a waiver with each payment. Sign conditional waivers until the money arrives, unconditional ones after.
- **Preliminary notices.** In many states, a sub who wants to keep lien rights must send a notice early in the job. The rules and deadlines differ by state, so check yours.
- **Change orders.** No written change order, no extra pay. Get the superintendent’s signature before you add a visit.

A simple cash-flow rule: do not let one GC owe you more than you can cover for 60 days. If a builder is slow, pause new phases until the last invoice clears. Invoice the day each phase is accepted, with photos attached; the [cleaning invoice template](https://broombook.com/tools/cleaning-invoice-template) is a start, and the [accounting guide](https://broombook.com/guides/cleaning-business-accounting) covers tracking receivables.

## A step-by-step plan to land your first construction cleaning contracts

Pick one lane (remodelers, a production builder or small commercial GCs), get your paperwork and OSHA cards ready, register on the bid platforms, then visit project offices and superintendents with a one-page sheet. Expect 30 to 90 days to a first paid job and six months to a steady builder.

1. **Week 1: paperwork.** Certificate of insurance with the limits GCs ask for, workers’ compensation, W-9, OSHA 10 cards scheduled.
2. **Week 2: platforms and lists.** Register on BuildingConnected, PlanHub and The Blue Book. Pull the last 90 days of building permits from your city or county for remodels and new homes; the contractor’s name is on most of them.
3. **Weeks 2 to 4: visits.** Stop at active job sites mid-morning and ask for the superintendent. Leave a one-page sheet: phases, per-square-foot starting prices, insurance, HEPA equipment, how fast you can mobilize.
4. **Weeks 3 to 6: bid everything that fits.** Answer each invitation within a day with unit prices by phase and alternates. Ask for the result on the ones you lose and note the winning price.
5. **Weeks 4 to 8: first job.** Confirm readiness the day before, arrive early, photograph before and after, finish on schedule, invoice the same day.
6. **Months 3 to 6: repeat.** After each job, ask the super which project is next and who runs it. Ask the builder for a vendor agreement with a price per plan.

Supply houses, flooring and cabinet showrooms and real estate agents who sell new construction all know which builders are busy; they are worth a visit too. Channels that apply to every kind of cleaning work are in [how to get cleaning clients](https://broombook.com/guides/how-to-get-cleaning-clients).

## How to keep a builder sending you every job

Builders keep the cleaner who shows up the day the trades leave, finishes before the walk, and never argues about a punch-list dust pass. Price matters less than reliability once you are in, so run every job like the audition it is.

- **Confirm the day before,** and tell the super by 8 am if anything on site blocks you.
- **Send photos at the end of each phase,** room by room, with anything you found damaged flagged before you leave.
- **Keep a crew lead the super knows by name.** Turnover on the crew is fine; turnover on the lead costs accounts.
- **Hold your unit prices for a year** per builder, and raise them with 30 days’ notice tied to wage changes.
- **Log your hours by phase** on every job, so your bids get sharper and your margins stop surprising you.

Software helps with the last two. Broombook is built for residential cleaning companies, and its crew app gives each cleaner checklists with photos and clock-in on their phone, which is a simple way to record job times and send a builder proof of what was done. It fits a company that cleans homes and runs construction cleans alongside, rather than a commercial-only sub managing pay applications. See [features](https://broombook.com/features) for what it covers.

## Frequently asked questions

### How do I get post construction cleaning contracts?

Register on the bid platforms commercial GCs use (BuildingConnected, PlanHub, The Blue Book), pull local building permits to find active builders and remodelers, visit job sites with a one-page sheet, and bid every invitation that fits with unit prices by phase. Then win the repeat work by finishing before the walk and invoicing the same day.

### How much should I bid per square foot for post construction cleaning?

Build it from your own production rate. In our hypothetical example, a 20,000 square foot office final clean at 250 square feet per labor hour came to about $0.19 per square foot, with a touch-up at about $0.04. Glass, overspray, high work and trades still on site all push the rate up, so time your jobs and use your numbers.

### Do I need OSHA 10 to do construction cleaning?

Federal OSHA describes its Outreach Training Program as voluntary and says the cards are not certifications, but most commercial general contractors require OSHA 10 for every worker on site, and some states and cities require it on public projects. Get the 10-hour construction course for your crew and the 30-hour course for your lead before you bid commercial work.

### What insurance do I need for construction cleaning jobs?

General liability with the GC and owner named as additional insured at the limits in the subcontract, workers’ compensation for employees, and usually commercial auto. Many subcontracts also ask for a waiver of subrogation. Tell your agent the work is construction cleanup, which can be rated differently from house cleaning.

### How long does it take to get paid on a construction cleaning contract?

Commercial GCs pay through monthly pay applications, usually 30 to 60 days after your invoice, and may hold retainage until closeout. Home builders typically pay net 15 to 30 after their walk, and flippers often pay on completion. Invoice the day each phase is accepted and keep your exposure to any one GC under what you can carry for 60 days.

### What is the difference between a rough clean and a final clean on a bid?

A rough clean happens during construction and clears debris and loose dust so finishes can go in; it is fast per square foot. A final clean happens after the trades finish and details every surface, including glass, fixtures, inside cabinets and floors; it takes several times longer per square foot. Bid them as separate unit prices, with touch-up visits priced per trip.

### Can I find new construction cleaning jobs without bid platforms?

Yes. Building permits list the contractor on most new homes and remodels, job-site visits reach superintendents directly, and supply houses and showrooms know which builders are busy. Platforms matter most for commercial GCs, who send invitations through them; for residential builders, a visit and a reliable first job usually matter more.
