Proudly Serving Charleston & Surrounding Areas
One of the first questions any office manager asks is simple: how much does office cleaning cost? For businesses in the Charleston area, the answer depends on your square footage, how often you need service, and the scope of work. This guide breaks down the three common pricing models — per square foot, per visit, and flat monthly — with realistic ranges for the Charleston market, so you can budget accurately and compare quotes on equal footing.
How much does office cleaning cost in Charleston?
In the Charleston, SC area, recurring commercial office cleaning typically runs $0.10–$0.18 per square foot per visit, or about $30–$55 per hour. Most offices pay between $250 and $2,500+ per month depending on size and how often they're cleaned.
These figures are ranges, not fixed prices — a small professional suite cleaned twice a week sits near the bottom, while a large corporate floor cleaned daily sits near the top. The exact number depends on the size of the space, the cleaning frequency, and the tasks included. An on-site walkthrough gives you an exact quote, but the ranges below let you sanity-check any estimate.
Office cleaning pricing models compared
Cleaning companies quote office work in three main ways. Understanding each helps you compare bids that look different on paper but describe the same work.
Per-square-foot pricing
Per-square-foot pricing is the most transparent model for recurring office cleaning. In Charleston, rates run about $0.08 to $0.20 per square foot per visit. Larger offices usually pay toward the lower end because crews work more efficiently across open floor plans, while small offices with many partitioned rooms pay toward the higher end. This model scales cleanly with your space and makes it easy to compare providers.
Per-visit pricing
Some companies quote a flat fee per cleaning visit, commonly $100 to $400 for small to mid-size Charleston offices. Per-visit pricing keeps budgeting simple when the scope is consistent — the same trash removal, vacuuming, restroom cleaning, and surface sanitation every time. It is easy to understand and predictable month to month.
Flat monthly pricing
Many offices prefer a single flat monthly fee that bundles a set number of visits. In Charleston this typically ranges from about $200 per month for a small office cleaned weekly to $2,500 or more for a large office cleaned nightly. A flat monthly rate turns cleaning into one predictable line item and usually locks in your per-visit rate for the contract term.
Monthly office cleaning cost by size
| Office Size | Typical Monthly Cost | Typical Frequency |
|---|---|---|
| Up to 2,500 sq ft | $250 – $600 | 1–2x / week |
| 2,500 – 5,000 sq ft | $500 – $1,200 | 2–3x / week |
| 5,000 – 10,000 sq ft | $1,000 – $2,400 | 3–5x / week |
| 10,000 – 20,000 sq ft | $1,900 – $4,500 | 5x / week |
| 20,000+ sq ft | $4,000+ | Daily |
Office cleaning rates by pricing method
| Pricing Method | Typical Charleston Range |
|---|---|
| Per square foot (per visit) | $0.10 – $0.18 / sq ft |
| Per hour | $30 – $55 / hour |
| Per month contract | $0.10 – $0.30 / sq ft per month |
These ranges reflect the Charleston metro, including Summerville, North Charleston, Goose Creek, and Moncks Corner. Every figure above is a range — an on-site walkthrough gives you an exact quote for your space. Your actual price depends on the specific factors below.
What factors change your office cleaning quote?
Several variables move your price within (or beyond) the ranges above. Knowing them helps you compare bids accurately and avoid surprises.
- Square footage and layout — open floor plans clean faster per square foot than offices with many small, partitioned rooms.
- Cleaning frequency — more frequent visits raise the monthly total but often lower the per-visit rate because the space stays easier to maintain.
- Scope of work — basic janitorial (trash, vacuum, restrooms, surfaces) is the baseline; add-ons like carpet extraction, floor stripping and waxing, and window cleaning are quoted separately.
- Restroom and kitchen count — these high-touch areas take the most labor and drive a large share of the cost.
- Foot traffic — client-facing lobbies and high-traffic offices need more attention and often daily service.
- After-hours scheduling — most offices are cleaned after hours; consistent scheduling is usually included, but tight or overnight windows can add a small premium.
How does office cleaning compare to medical or industrial cleaning?
Standard office cleaning is generally the least expensive commercial cleaning per square foot. Medical office cleaning costs 25% to 50% more because of OSHA and HIPAA compliance and EPA-registered hospital-grade disinfectants. Industrial and warehouse cleaning is often lower per square foot ($0.08–$0.18) but higher per visit because of the large total area and heavy-duty equipment. If your office has clinical or high-compliance needs, expect to pay above the standard office ranges.

How to get an accurate office cleaning quote
Because so many variables affect the price, the most reliable step is a free on-site walkthrough. During the visit, a reputable provider measures cleanable square footage, counts restrooms and kitchens, notes flooring types, and asks about your frequency and scope. Ask each company to quote in both per-visit and monthly formats, confirm that labor, supplies, equipment, and insurance are included, and get the scope of work in writing. Be cautious of quotes far below the ranges above — they often signal undertrained staff, thin coverage, or missing insurance.
Frequently Asked Questions
How much does office cleaning cost per square foot in Charleston?+
Office cleaning in Charleston typically costs $0.08 to $0.20 per square foot per visit. Larger open offices pay toward the lower end because crews work more efficiently, while smaller offices with many partitioned rooms pay toward the higher end. The rate also depends on frequency and scope.
What is a typical monthly office cleaning cost?+
Monthly office cleaning in the Charleston area ranges from about $200 for a small office cleaned weekly to $2,500 or more for a large office cleaned nightly. Mid-size offices cleaned two to three times per week commonly fall between $600 and $1,800 per month. A flat monthly fee bundles a set number of visits into one predictable line item.
Is it cheaper to pay per visit or per month for office cleaning?+
The two usually work out to the same total — a monthly fee is simply a set number of per-visit charges bundled together. Monthly contracts often lock in a slightly better per-visit rate and simplify budgeting, while per-visit billing offers more flexibility if your needs change month to month.
Why is one office cleaning quote so much lower than another?+
Large gaps usually come down to scope, staffing, and insurance. A very low quote may cover fewer tasks, use undertrained or uninsured labor, or skip high-touch areas. Always compare the written scope of work, confirm insurance and background checks, and make sure both quotes describe the same frequency and tasks before choosing on price.
Does frequency affect the per-visit price?+
Yes. More frequent cleaning usually lowers the per-visit rate because the office stays easier to maintain between visits, so each visit takes less time. Daily service has a higher monthly total than weekly service but often a lower cost per individual visit.
