Post Construction Cleaning Cost: Price Per Square Foot Guide (2026)

If you’re a general contractor, developer, or property manager, “how much does post construction cleaning cost?” is usually the first question — and the honest answer is that it’s priced per square foot, and the rate depends on a handful of specific factors. This guide breaks down what drives the price, the typical ranges in 2026, and exactly how to get a quote you can budget against.

How post construction cleaning is priced

There are three common ways cleaning companies price post construction work. Understanding which one you’re being quoted on makes it far easier to compare bids apples-to-apples and avoid surprises on the invoice.

• Per square foot — the most common method for commercial projects. The cleaner walks the space (or reviews the plans), assesses the phase and condition, and quotes a rate per square foot of finished area.
• Hourly — sometimes used for small projects, touch-ups, or when the scope is unpredictable. Harder to budget because the total depends on crew speed and how much dust is actually there.
• Flat project bid — a single line-item price for the whole job, usually derived from a per-square-foot calculation plus special items like lift work, pressure washing, or debris haul-off.

Post construction cleaning price per square foot in 2026

Rates vary by region, phase, and building type, so treat the table below as a planning range rather than a firm quote. Dense-glass high-rises and compressed schedules push toward the top of each range; simple open-plan build-outs sit near the bottom.

For context, the overall U.S. commercial range in 2026 is roughly $0.15–$0.80 per square foot. A 5,000 sq ft suite often lands around $1,500–$3,000; a 20,000 sq ft office can run $6,000–$15,000 depending on spec. Florida trends to the higher end because of tight construction labor.

What drives the price per square foot

Two identical-size spaces can be priced very differently. These are the factors that move the number the most:

• Phase of clean — a rough clean (between trades) is cheaper per square foot than a detailed final clean or a touch-up/punch-list clean.
• Debris and dust level — heavy drywall dust, adhesive residue, paint overspray, and leftover materials all add labor.
• Height and lift work — high ceilings, exposed ductwork, and tall glass that need lifts or water-fed poles raise the rate.
• Glass surface area — floor-to-ceiling glass (common in modern offices and towers) is labor-intensive to detail streak-free.
• Floor type and finish — polished concrete, VCT strip-and-wax, terrazzo, or delicate stone each require different processes and time.
• Schedule compression — hitting a tight certificate-of-occupancy date with nights and weekends costs more than a relaxed timeline.
• Site access — loading docks, elevator reservations, and occupied-adjacent areas all affect how fast a crew can work.

Rough clean vs final clean vs touch-up: why each is priced differently

Most projects are cleaned in phases, and each phase is priced differently because the labor per square foot is different. For the full breakdown, see our guide to the 3 phases of post construction cleaning.

What’s usually NOT included in the base price

Watch for these items, which are often quoted separately. If they’re not itemized, ask — this is where “cheap” bids balloon later:

• Dumpster rental and large debris haul-off
• Exterior pressure washing of entryways and hardscape
• Floor stripping, waxing, or sealing (vs. a basic clean)
• Lift or scaffolding rental for very high work
• Specialty surfaces (stone polishing, restoration cleaning)

Why you shouldn’t trust a price without a walkthrough

Any company that gives you a firm per-square-foot number before seeing the space (or the plans) is guessing. Debris level and glass area alone can swing the labor significantly. A reputable cleaner will either walk the site or review your plans, then give you a written, line-item quote — no vague “allowances” that balloon on the invoice.

How to get an accurate post construction cleaning quote fast

1. 1Share your square footage, floor plan, and target handover/CO date.
2. 2Note anything unusual — high ceilings, extensive glass, delicate finishes, occupied-adjacent areas.
3. 3Say which phases you need (rough, final, touch-up, or all three).
4. 4Ask for a written, itemized quote and a certificate of insurance (COI) naming your firm and the owner.

SBS provides a written, line-item post construction cleaning quote within 24 hours of a walkthrough or plan review — insured, bonded, and COI-ready for general contractors and owners across Florida and New England. In high-glass markets like Miami and fast-growing corridors like Orlando, we build the schedule around your certificate-of-occupancy date.

Frequently asked questions

Is post construction cleaning priced per square foot or per hour?

For commercial projects it’s almost always per square foot, because it’s easier to budget and compare. Hourly is more common for small touch-ups or unpredictable scopes.

How much does a final construction clean cost?

As a planning range, roughly $0.30–$0.75 per square foot for a standard commercial final clean, higher for heavy-glass or high-rise work. Always confirm with a walkthrough-based quote.

Why are two quotes for the same building so different?

Usually because they cover different scopes. One may include exterior glass, floor finishing, and debris haul-off while the other treats them as add-ons. Normalize the bids against the same written scope and the real difference — in crew, insurance, and equipment — becomes visible.

Does Florida cost more than other states?

Often, yes. High-growth markets with tight construction labor — Florida, Texas, Georgia — tend to price toward the upper end of the range because crews are in demand. Miami’s high-glass towers add cost on top of that.

Worked example: a 15,000 sq ft office build-out

Say you’ve got a 15,000-square-foot office final clean with a moderate amount of glass and a standard schedule. At a mid-range final-clean rate of about $0.45 per square foot, that’s roughly $6,750 before adjustments. Add extensive floor-to-ceiling glass and a rush schedule and the number climbs; keep it simple with a relaxed timeline and it settles lower. This is exactly the kind of quick math our calculator does for you — then we confirm it with a walkthrough.

How to keep post-construction cleaning costs down

1. 1Book a rough clean between trades so the final clean has less to fight.
2. 2Sequence the final clean after the last dusty trade — clean once, not twice.
3. 3Bundle floor finishing and window cleaning into one scope for better pricing.
4. 4Give the cleaner a clear, written scope so the quote is firm and comparable.
5. 5Share your CO date early so the crew is sized right the first time.

How to budget post-construction cleaning into a project

Post-construction cleaning belongs in the project budget from the start, not as an afterthought once the build is nearly done. Because it’s priced per square foot, you can estimate it early from the floor plans — even before finishes are chosen — and refine it as the scope firms up. General contractors typically carry it as a subcontractor line; owners and developers should confirm whether the GC’s number includes the final clean or expects the owner to arrange it separately, because that assumption gap is a common source of last-minute scrambles.

A useful rule of thumb: budget the final clean at a mid-range rate for your building type, then add a contingency for glass, height, and schedule if any of those are significant. Lock the number with a walkthrough-based quote once the space is far enough along to see the real dust and finish conditions.

Is post-construction cleaning tax-deductible or capitalizable?

For businesses, cleaning tied to a build-out is generally a project cost and is often capitalized with the improvement rather than expensed — but treatment depends on your situation and jurisdiction. Confirm with your accountant; the point for planning is simply that it’s a legitimate, expected part of the project cost, not an optional extra.
