What Commercial Cleaning Costs in DC, Maryland & Virginia — and Why the Lowest Bid Costs More

Facility leaders comparing cleaning proposals in the DMV usually start with one question — what should this cost? — and end up asking a better one: why do two bids for the same building differ by 40%? Here are the real numbers, the factors behind them, and the reason the cheapest proposal is usually the most expensive decision on the table.

The benchmarks

• Recurring janitorial service in the region typically runs $0.03–$0.05 per square foot per cleaning.
• A 10,000 sq ft office cleaned three times weekly lands around $1,500–$2,000 per month — roughly $115–$150 per visit.
• Smaller offices generally budget $800–$1,200/month; mid-sized facilities (10,000–20,000 sq ft) $1,500–$4,000/month; larger or specialized facilities $3,000–$7,000+/month.
• As an annual planning figure, $1–$2 per square foot per year holds for most office space — about $6,000–$10,000/year for 5,000 sq ft, $25,000–$40,000/year for 20,000 sq ft.
• Facilities with elevated standards — medical, food service, fitness — should expect to spend 30–50% more.

What actually drives the price

Square footage. Total spend scales with size, though per-cleaning rates often improve in larger buildings.

Frequency. Daily service costs more per month than weekly but less per visit — and it changes what the program accomplishes, from restoring appearance to preventing buildup.

Industry requirements. Medical facilities carry disinfection protocols and PPE requirements. Kitchens carry grease and health-code work. Gyms carry equipment sanitization. Compliance is labor, and labor is the price.

Labor market and access. Urban DC wages run higher than suburban Maryland or Virginia, and after-hours or secured-access buildings add coordination cost.

Layout and surfaces. Restroom count, breakrooms, and specialty flooring drive labor time more than raw square footage does.

Why the lowest bid costs more: a Rockville case

An 18-person CPA firm in Rockville was paying a budget vendor $2,250 per month — a number that looked like a win in procurement. Then the real invoice arrived, spread across the year: the office manager was losing 3–4 hours every week to the vendor — logging complaints, chasing re-cleans, walking the office before client meetings because the service could not be trusted to have handled it. Price that time at a professional salary and the "savings" were gone several times over, before counting the client-facing risk during tax season.

The firm moved to a documented program at $3,350 per month. The complaints stopped. The re-cleans stopped. The office manager got her week back. The partners' verdict on the extra $1,100: it felt "invisible" — because the friction it replaced had been the real cost all along.

That is the pattern behind most budget bids. A vendor pricing below market is not more efficient; they are staffing thinner, supervising less, and leaving the quality control to your staff. You pay the difference either way. The only question is whether it appears on the invoice or in your team’s calendar.

How to get a number you can trust

Accurate pricing requires a walkthrough — measured square footage, traffic patterns, priority zones, access and timing, compliance requirements. Any bid produced without one is a guess, and guesses get corrected later, in your favor or not. When you compare proposals, compare scopes, not totals: what is written down, at what frequency, supervised by whom, and verified how. A documented scope is the only version of a price that means anything.

The bottom line

Expect $0.03–$0.05 per square foot per cleaning in the DMV, adjusted for frequency, industry, and building specifics. Then evaluate the bid on total cost of ownership: invoice plus friction. The organizations that run that math almost never buy the cheapest line item — and their facilities show it.
