Hiring a commercial cleaning company in Boston means matching a contractor to a very specific building stock: older brick and stone offices, glass towers in the Financial District and Seaport, lab space in Cambridge and the Longwood area, and suburban flex buildings along Route 128. The right contract spells out a nightly scope per area, a winter plan for salt and slush, the periodic floor and carpet work, and proof that the contractor meets Massachusetts workers' compensation and classification rules.
This guide walks through each of those points so you can write a clear request for proposals and compare bids on the same terms.
Boston's building types and what they ask of a cleaning crew
Downtown and Back Bay office towers. Class A buildings usually come with property management rules: loading dock hours, freight elevator bookings, badge access, contractor safety orientations and sometimes a required labour arrangement for the building's janitorial staff. Many large Boston office buildings are cleaned by unionized janitors represented by SEIU 32BJ, so a tenant hiring its own crew should first ask the landlord what the lease and building rules allow.
Older mid-rise offices. Buildings in the South End, Downtown Crossing or around Government Center often have narrow stairwells, small elevators, hardwood or stone floors, and radiators that collect dust. These need careful floor care and more hand work, which takes more labour per square foot than an open modern floor.
Life science and lab buildings. Kendall Square, the Seaport and the Longwood Medical Area have a large share of wet labs and vivarium-adjacent space. Office areas in these buildings get standard janitorial service, but lab zones usually follow the tenant's own EHS rules: which areas the crew may enter, what can be touched, how waste is separated, and which disinfectants are approved. Cleaning staff should never handle biological, chemical or sharps waste unless the contract and training cover it.
Medical and dental offices. Clinics need restrooms, exam rooms and waiting areas disinfected with EPA-registered products, with attention to dwell times on the label. Our post on how often medical offices should be cleaned covers frequency by room type, and the same logic applies in Massachusetts.
Suburban flex and warehouse space. Burlington, Waltham, Woburn and the I-495 belt have many buildings that combine offices with shop, warehouse or light manufacturing areas. Those need two scopes in one contract: nightly office cleaning plus scheduled floor scrubbing, high dusting and degreasing on the industrial side.
What Boston offices typically pay
Boston is one of the higher-cost cleaning markets in the US because of local wage levels. As a rough planning range, not a quote, nightly janitorial service five days a week often runs about $0.15 to $0.35 per square foot per month. For a 10,000 square foot office that is roughly $1,500 to $3,500 a month. Small offices cleaned two or three times a week commonly land between $600 and $1,600 a month.
The numbers move with:
- The share of the space that is restrooms, kitchens and break rooms.
- Floor types (carpet, VCT, sealed concrete, stone, hardwood).
- Whether consumables such as paper, soap and liners are included.
- Building access rules and the visit window.
- Union or prevailing wage requirements set by the building or the lease.
- Lab, clinical or secure areas that need trained staff.
Hourly quotes in the Boston area commonly fall in the $35 to $65 range per labour hour depending on what the rate includes. If a bid is hourly, ask how many hours each visit covers and what tasks fit in that time. For a quick estimate by size and frequency, the pricing calculator gives a starting figure.
Planning the winter scope
From November to March, Boston entrances take a beating. Rock salt and calcium chloride come in on every boot, leave white residue on floors and slowly etch stone and polished concrete. A cleaning contract written in July often ignores this.
Ask each bidder to price a winter scope that covers:
- Extra entrance and lobby mopping during storms, with neutral or salt-removal cleaner rather than plain water.
- More frequent vacuuming of walk-off mats, plus who supplies and swaps the matting.
- Carpet extraction scheduled for early spring to pull out the season's salt.
- A plan for wet-floor signage and slip control near doors.
Sidewalk snow clearing itself is usually a separate contract with a snow removal company, since Boston requires property owners to clear sidewalks promptly after a storm. Make sure the two contractors know where one job ends and the other begins, especially at vestibules and ramps.
Massachusetts rules a cleaning contract should reflect
Workers' compensation. Massachusetts requires employers to carry workers' compensation insurance, and the Department of Industrial Accidents enforces it. Ask for a certificate showing the contractor's policy is active, and keep it on file.
Worker classification. Massachusetts uses a strict three-part test to decide whether a worker is an independent contractor. The janitorial industry has had high-profile cases over cleaners classified as franchise owners or contractors when they worked like employees. A bidder who pays its cleaners as W-2 employees is a lower-risk choice than one built on subcontracted individuals.
Workplace safety. Private-sector cleaning crews in Massachusetts fall under federal OSHA. The Hazard Communication Standard requires chemical labelling, safety data sheets and training, and the Bloodborne Pathogens Standard applies where staff may contact blood or other potentially infectious material, as in clinics.
Earned sick time and wage laws. The Massachusetts Earned Sick Time Law and the state Wage Act apply to cleaning employees. These are the contractor's obligations, but a contractor who ignores them tends to have high turnover, which shows up as missed tasks in your building.
Liability insurance. Request a certificate of general liability insurance, and ask for your company or landlord to be named as additional insured where the lease requires it.
A short checklist for comparing Boston bids
- A written scope per area with a frequency for each task.
- Consumables included or billed separately, and at what markup.
- The winter scope, priced up front.
- Periodic work (carpet extraction, floor stripping and refinishing, window and partition glass, high dusting) with dates and prices.
- Supervision: who inspects, how often, and how complaints are handled.
- Proof of workers' compensation and liability coverage, and how the crew is employed.
- Building requirements: access, union rules, lab or clinical training.
- Term, notice period and how price changes work at renewal.

Frequently asked questions
How much does commercial cleaning cost in Boston?
For nightly office cleaning five days a week, a typical planning range is about $0.15 to $0.35 per square foot per month, or roughly $1,500 to $3,500 for 10,000 square feet. Restroom count, floor types, consumables and building rules move the figure. Periodic work like carpet extraction is quoted separately.
Can a tenant hire its own cleaning company in a Boston office tower?
It depends on the lease. Many Class A buildings include janitorial service in the operating costs and use the landlord's contractor, sometimes with union staff. Check the lease and ask property management before you request bids.
Do Boston cleaning contracts change in winter?
The base price usually stays the same, but salt and slush add entrance mopping, mat service and an early spring carpet extraction. Ask bidders to price the winter scope in the contract so it is not added as extras later.
What should a Massachusetts cleaning contractor provide before work starts?
Ask for a current workers' compensation certificate, a general liability certificate, a written scope with frequencies, and an explanation of how their cleaners are employed. Lab or clinical sites should also ask about chemical and bloodborne pathogens training.
