Proudly Serving Charleston & Surrounding Areas
Janitorial services keep your facility clean, safe, and presentable day after day — but pricing can be confusing because providers quote in different ways. For businesses in the Charleston area, understanding how janitorial services cost is calculated helps you budget accurately and compare bids fairly. This guide covers the three common janitorial pricing models — per square foot, hourly, and per visit or month — with realistic Charleston ranges by facility type, plus the factors that move your rate.
How much do janitorial services cost in Charleston?
Commercial janitorial service in Charleston, SC generally costs $30–$55 per hour or $0.10–$0.30 per square foot per month, with most businesses paying roughly $700–$2,800 per month. Medical and industrial facilities sit at the higher end.
Every figure here is a range, not a fixed price. The exact number depends on your square footage, cleaning frequency, facility type, and scope of work. An on-site walkthrough gives you an exact quote, but the ranges below let you evaluate any estimate.
Janitorial pricing models explained
Janitorial work is quoted three main ways. Each fits a different situation.
Per-square-foot pricing
Per-square-foot pricing, around $0.07 to $0.18 in Charleston, is the standard for recurring janitorial contracts. It scales with facility size and is the easiest model to compare across providers. Large, open facilities pay toward the lower end; smaller or highly partitioned spaces pay more per square foot.
Hourly pricing
Hourly janitorial rates in Charleston generally run $25 to $45 per hour per cleaner, reflecting local wages plus overhead, supplies, insurance, and supervision. Hourly pricing works best for variable-scope work, deep cleans, or day porter coverage where the exact task list changes. It can be harder to predict for recurring maintenance because the total depends on how long the work takes.
Per-visit and monthly pricing
Many facilities prefer a flat per-visit fee ($150 to $400 is common) or a bundled monthly rate. This turns janitorial service into a predictable line item and works well when the scope is consistent from visit to visit. Monthly agreements usually lock in your rate for the contract term.
Janitorial rate ranges by type
| Service Type | Typical Charleston Rate |
|---|---|
| Standard hourly | $30 – $55 / hr |
| Per sq ft monthly contract | $0.10 – $0.30 / sq ft per month |
| Medical / clinic | +15% – 30% |
| Industrial / warehouse | +20% – 40% |
| Day porter (on-site daytime) | $25 – $45 / hr |
| One-time deep clean | $0.15 – $0.35 / sq ft |
Typical monthly janitorial contracts
| Facility | Typical Monthly Cost | Frequency |
|---|---|---|
| Small office / clinic | $700 – $1,500 | 2–3x / week |
| Mid-size office (10k sq ft) | $1,500 – $3,000 | 3–5x / week |
| Large / medical building | $3,000 – $8,000+ | Daily |
| Warehouse / industrial | $1,200 – $6,000+ | Varies |
These ranges apply across the Charleston metro, including Summerville, North Charleston, Goose Creek, and Moncks Corner. Facility type has a big impact — clinical and industrial spaces carry a premium. Every figure is a range; an on-site walkthrough gives you an exact quote for your facility.
What factors affect janitorial pricing?
Several variables determine where your quote lands within these ranges.
- Facility type — medical and food-service spaces require specialized products and training, raising the rate; standard offices and retail are lower.
- Frequency — daily service costs more monthly than a few visits per week, but keeps the facility easier (and cheaper per visit) to maintain.
- Square footage and layout — larger open spaces are cheaper per square foot; partitioned or multi-floor facilities cost more.
- Scope of work — restrooms, break rooms, and high-touch disinfection are labor-intensive; project add-ons like floor care and carpet extraction are quoted separately.
- Supplies and consumables — confirm whether paper products, liners, and soap restocking are included or billed separately.
- Compliance requirements — OSHA, EPA-registered disinfectants, and background-checked staff add cost but protect your facility.
Janitorial services vs. day porter service
Standard janitorial service is usually performed after hours on a set schedule. A day porter, by contrast, works on-site during business hours to handle restrooms, spills, lobbies, and common areas in real time — typically billed hourly at $25 to $45 per hour. Many facilities combine an after-hours janitorial contract with daytime porter coverage for high-traffic buildings. If you are weighing the two, our day porter service page explains what porter coverage includes.
