What is post-construction cleaning?

Post-construction cleaning is the specialized clean-up done after new construction or a major remodel. It has three phases: a rough clean after framing and drywall, a light clean once paint and cabinets are in, and a final touch-up 24–48 hours before handover. It is distinct from deep cleaning and move-out cleaning because it deals with construction dust, leftover materials and protective films.

How much does post-construction cleaning cost per square foot in 2026?

In 2026 most US crews charge $0.30–$0.50 per square foot for residential post-construction cleaning and $0.15–$0.35 for large commercial buildouts. Hourly work runs $50–$90 per cleaner because of PPE, equipment wear and required skill. A 2,500 sq ft new home usually totals $1,000–$1,500 across all three phases.

How long does a post-construction clean take?

A single-family home of 2,000–3,000 sq ft typically needs a two- to three-person crew for one day per phase — roughly 20–35 total labor-hours across rough, light and final. Add 30–50% for large custom homes, exposed beams or extensive tile and glass work. Delays between trades can stretch the calendar by days even if your on-site hours stay the same.

What supplies do I need for post-construction cleaning?

A HEPA-filter shop vacuum, microfiber cloths and pole dusters, a heavy push broom, an extension pole and ladder, razor blade scrapers with holders, grout haze remover, streak-free glass and stainless cleaners, contractor-grade trash bags, and full PPE: N95 or better respirator, safety glasses, cut-resistant gloves and closed-toe boots.

Do I need special insurance for post-construction jobs?

Yes. Standard residential janitorial policies often exclude construction cleanup. Call your agent and confirm in writing that your general liability covers post-construction work, and expect the general contractor to request a certificate of insurance, a W-9 and sometimes proof of workers' comp before your first invoice is paid.

Post-Construction Cleaning Checklist (2026 Guide)

A real post-construction cleaning checklist has three parts, not one: a rough clean while drywall dust and scraps are everywhere, a light clean once trim and paint are done, and a final touch-up clean the day before handover. Miss that structure and you will re-clean the same rooms three times, burn a full day of labor, and still leave grout haze, adhesive residue and screw shavings behind. This guide walks through every phase, gives you the room-by-room task list most general contractors expect, and covers the gear, pricing and safety details that separate a $500 disaster from a $2,500 clean.

What counts as post-construction cleaning?

Post-construction cleaning is the specialized clean-up done after new construction, a major remodel, or a substantial addition — anything from a full custom home to a gut kitchen or a commercial buildout. It is not a deep clean and it is not a move-out. Deep cleans work on maintained homes; move-outs prep an empty but lived-in space. Post-construction jobs deal with fine construction dust that coats every surface (including inside HVAC vents), leftover materials (nails, drywall mud, caulk drips, sawdust), and protective films on windows, appliances, tubs and toilets that must come off without scratching the surface underneath. Skipping any of that is what gets you called back — or not paid.

The three phases: rough, light, final

General contractors expect the work in phases because different trades finish at different times. Trying to compress it into one visit costs you money because early dust from drywall sanding will settle back onto anything you cleaned before the painters and finish carpenters leave. Plan the job as three visits — or three passes on a very short remodel — and quote them separately:

Phase 1 — Rough clean: after framing, drywall and any heavy demolition, before paint. Focus on debris removal and gross dust knock-down.
Phase 2 — Light clean: after paint, cabinets and trim are installed, before flooring is sealed and appliances are set. Detail wipe-downs everywhere.
Phase 3 — Final touch-up: 24–48 hours before handover to the homeowner or tenant. White-glove finish, protective films removed, windows spotless.

Phase 1 — Rough clean checklist

This phase is more like construction site cleanup than housekeeping. You are working alongside or right after trades, so wear PPE and bring contractor bags, a HEPA shop vac and a heavy push broom.

Pick up all large debris: wood offcuts, drywall scraps, packaging, drink cans, pizza boxes.
Sweep every hard floor with a heavy push broom, corner to corner, twice.
HEPA vacuum the entire floor after sweeping — regular shop vac dust bags let fine drywall dust straight back into the air.
Knock down dust from ceilings, ledges, door frames, window sills and light fixtures with a microfiber duster on an extension pole.
Vacuum window tracks and door frames.
Remove stickers, tape residue and paint splatter from unfinished surfaces.
Bag and haul debris to the site dumpster — never to the client's curb without asking.
Wet-mop hard floors after the dust has settled overnight, if possible.

Phase 2 — Light clean checklist

By this point paint is dry, cabinets and trim are in, and the space is starting to look finished. Your job is to remove every trace of construction dust from every surface — and dust hides in places you would not check on a normal clean.

Wipe down all walls and baseboards top-to-bottom with a slightly damp microfiber (test paint first — flat paint marks easily).
Clean inside and outside of all cabinets, drawers and closets, including the tops.
Wipe every door, both sides, plus door frames and hinges.
Damp-wipe window sills, tracks and frames; clean glass on both sides.
Vacuum and wipe HVAC vents, returns and thermostat covers — construction dust in ductwork will circulate for months.
Wipe every light fixture, ceiling fan blade and switch plate.
Clean inside outlets and switch boxes with a dry brush (power off).
Wipe down all appliances, fixtures and hardware.
Sweep, vacuum and mop all floors again.

Phase 3 — Final touch-up checklist

This is the walk-through clean. The client or general contractor is going to open every cabinet, run a finger along every ledge and check every window. Treat it as a punch list, not a general tidy-up.

Remove all protective films from windows, tubs, sinks, toilets, appliances and stainless steel.
Polish every glass surface: windows, shower enclosures, mirrors, glass cabinets.
Buff stainless steel, chrome and brushed nickel with the grain, not against it.
Remove grout haze from new tile with a haze remover (test in an inconspicuous area first).
Vacuum any new carpet with a HEPA-filter vacuum; steam or damp-mop new hard floors per the manufacturer's spec.
Wipe down every horizontal surface one more time — dust settles between phases.
Empty and wipe out every trash bin, then reline.
Do a final walk with a flashlight to catch smudges, missed spots and adhesive residue at eye level and floor level.

What gear do you actually need?

Post-construction cleaning burns through consumables and destroys residential equipment. Budget for the right gear and expect to replace it more often than on standard cleans:

HEPA-filter shop vacuum (regular shop vacs recirculate fine dust).
Backpack HEPA vacuum for speed on floors and walls.
Microfiber cloths and pole dusters (dozens — you will trash them).
Heavy-duty push broom and a soft-bristle broom.
Extension pole, ladder or a stable A-frame — most rooms are 9 to 12 feet.
Razor blade scrapers with holders (never bare) for paint and adhesive removal, and grout haze remover for tile.
Streak-free glass cleaner and stainless-steel cleaner with a grain-safe cloth.
Contractor-grade trash bags and a way to haul them.
PPE: N95 or better respirator, safety glasses, cut-resistant gloves, closed-toe boots.

How much should you charge for post-construction cleaning in 2026?

Post-construction jobs pay well because most residential cleaners will not touch them. Typical 2026 US ranges:

Per square foot: $0.30–$0.50 for residential and $0.15–$0.35 for large commercial buildouts.
Hourly: $50–$90 per cleaner — higher than residential because of PPE, wear on equipment and skill required.
Rough clean: usually quoted per hour or by dumpster loads hauled.
Light clean: the bulk of the invoice, often 60–70% of the total.
Final touch-up: a flat $200–$600 depending on square footage.

A 2,500 sq ft new home typically quotes at $1,000–$1,500 for all three phases combined; a commercial retail space of 5,000 sq ft can hit $2,500–$4,000. Always quote each phase separately in writing so change orders and delayed trades do not eat your margin. Add 10–15% if the site does not have working power, water or an on-site dumpster.

Safety, insurance and liability

Post-construction sites are working construction sites until the final walk. Nail guns, exposed edges, wet paint and fine silica dust from drywall sanding are all real hazards. Two non-negotiables before you take these jobs:

General liability with construction-cleanup coverage. A standard residential janitorial policy often excludes it — call your agent and confirm in writing.
OSHA-appropriate PPE for every cleaner on site: respirator, eye protection, gloves, hard hat if trades are still overhead.

You should also expect the general contractor to require proof of insurance, W-9 and sometimes workers' comp before you can invoice. Have those documents ready as a PDF — it is often what wins the bid over a competitor who fumbles the paperwork.

How do you win and run these jobs profitably?

The margin in post-construction cleaning is real, but only if you quote each phase in writing, capture before-and-after proof photos so the GC signs off cleanly, and invoice fast — construction cash flow slows down after handover, not before. CleanOS builds phased estimates you can send from your phone, requires mandatory before/after photos per room so nothing gets disputed at final walk, sends the invoice the moment the job is marked complete, and stores your COI and W-9 to attach automatically. That paperwork loop is usually the difference between getting the next job on the same contractor's next build — or losing it to whoever answered faster.

Post-construction cleaning is not harder than deep cleaning; it is just structured differently. Run it in three phases, use the room-by-room checklist above, charge for the specialized gear and risk you are taking on, and treat the paperwork as part of the service. Do that and general contractors will call you back before they finish the framing on the next project.
