A Houston office cleaned five nights a week typically costs about $0.10 to $0.25 per square foot per month, or roughly $1,000 to $2,500 a month for 10,000 square feet. Smaller offices on two or three visits a week often fall between $400 and $1,100 a month, while clinics and labs near the Texas Medical Center run noticeably higher because of disinfection scope. Warehouses usually cost less per square foot, since large open floors go quickly with ride-on equipment.
Treat these as planning figures in US dollars, not a quote. The rest of this guide explains how Houston contractors build a price and what to check before you sign.
Typical monthly ranges by facility
The office figures assume standard after-hours service: trash and recycling, restrooms, break rooms, vacuuming and mopping, and dusting of reachable surfaces. Supplies such as liners and cleaning chemicals are usually included; paper towels, toilet paper and hand soap often are not.
| Facility | Visits per week | Typical monthly range |
|---|---|---|
| Small office, 1,500 to 3,000 sq ft | 2 to 3 | $400 to $1,100 |
| Office, 5,000 sq ft | 5 | $700 to $1,400 |
| Office, 10,000 sq ft | 5 | $1,000 to $2,500 |
| Office, 25,000 sq ft | 5 | $2,300 to $5,500 |
| Medical clinic, 4,000 sq ft | 5 to 6 | $1,100 to $2,600 |
| Warehouse, 50,000 sq ft (office area plus floor scrubbing) | 3 to 5 | $1,500 to $4,000 |
Per-foot rates shrink as buildings get bigger. Travel, supervision and setup cost about the same for 2,000 square feet as for 20,000, so a small suite in Westchase can pay more per foot than a full floor Downtown.
Contractors that bill by the hour in Houston commonly charge $28 to $50 per labour hour. The low end usually means supplies and supervision are extra; the high end often includes them, along with insurance and a site lead. An hourly quote is only useful if it states how many hours per visit and what tasks fit inside them.
Local conditions that change a Houston bid
Humidity and mold risk. Houston air stays damp for much of the year. Restrooms, janitor closets, ceiling vents near supply diffusers and any spot with past water intrusion need more attention than they would in a dry climate. A careful bid includes routine checks of vents and grout lines and spells out what happens if a crew finds visible growth (report it, do not just wipe it).
Storm season. Hurricane season runs June through November, and heavy rain events can flood lobbies, parking garages and ground floors with little warning. Ask whether the contractor offers emergency water extraction and cleanup, at what rate, and how fast they can respond. Agreeing on that rate before a storm is far better than negotiating during one.
Pollen and mud at the door. Spring oak pollen coats glass, sills and entrance floors, and rain brings mud in from surface lots. Buildings with heavy foot traffic usually need entrance mats changed more often and glass doors cleaned on every visit for a few weeks each year.
Sprawl and drive time. Greater Houston covers a huge area. A crew based in the Energy Corridor may price a site in Clear Lake or The Woodlands higher simply because of drive time. Choosing a contractor with people already working near your building can lower the bid without cutting the scope.
Industry mix. A tower office, an outpatient clinic in the Medical Center and a terminal office along the Ship Channel need very different work. Clinics need disinfection of exam rooms and touch points with hospital-grade products and proper dwell times. Industrial sites may need degreasing, PPE and site safety orientation before the crew can start.
Work usually priced on top of the base contract
Most monthly prices cover routine cleaning only. These items tend to appear as separate lines:
- Carpet hot water extraction, often quoted per square foot or per room.
- Hard floor stripping and refinishing, or burnishing on a set schedule.
- Interior and exterior window cleaning above the ground floor.
- High dusting of vents, beams and light fixtures, especially in warehouses.
- Post-construction cleanup after a renovation or tenant fit-out.
- Day porter service for lobbies, restrooms and conference rooms during business hours.
When you compare proposals, check whether these items are included, quoted separately or missing. A low monthly figure can hide an expensive floor program. Our specialized cleaning page outlines what each of these jobs involves.
Texas tax and insurance points to settle early
Texas generally treats janitorial work on commercial property as a taxable service, so expect state and local sales tax on the invoice (8.25% is the combined rate in the City of Houston). Confirm the treatment for your building with your accountant or the Texas Comptroller, and make sure every bid shows tax the same way so you compare like for like.
Texas is also unusual in that private employers can choose not to carry workers' compensation insurance. A contractor that opts out may quote lower, but an injury on your property can become a dispute about who pays. Ask each bidder for a certificate of general liability insurance and a clear answer on workers' comp, and have your property's own insurer review the contract terms.
Comparing quotes without getting burned
Ask every bidder to price the same written scope: the task list by area, the visit schedule, what supplies are included and how periodic work is billed. Then look at:
- Hours per visit. Divide the monthly price by the visits, then by the stated hours. A bid with too few hours for the space will look cheap and fall short within a few weeks.
- Supervision. Who inspects the work, how often, and how you report a problem.
- Term and exit. A 30 day termination clause protects you if quality drops. Watch for automatic renewals with long notice periods.
- Price review. Many contracts allow an annual increase. Ask for it to be capped or tied to a stated index.
The pricing calculator gives a quick range to sanity-check bids against before you meet contractors.
Frequently asked questions
How much does office cleaning cost per square foot in Houston?
For nightly service five days a week, Houston offices typically pay about $0.10 to $0.25 per square foot per month. Larger buildings with simple layouts sit near the low end, while small suites, offices with many restrooms and spaces with client traffic sit near the high end. Periodic floor and carpet care is usually extra.
Is commercial cleaning taxable in Texas?
In most cases, yes. Texas taxes janitorial and cleaning services performed on nonresidential property, so Houston businesses normally see sales tax on their cleaning invoices. Check the details for your situation with your accountant or the Texas Comptroller's guidance on real property services.
Why do medical clinics cost more to clean?
Clinics need more than tidy floors. Exam rooms, waiting areas and restrooms require disinfection with approved products left wet for the label's contact time, plus careful handling of waste streams and frequent attention to touch points. That takes more labour per square foot and staff trained for healthcare settings.
Should a Houston cleaning contract cover flood cleanup?
It is worth agreeing on emergency rates and response times in advance, even if the work is billed separately. After a heavy storm, contractors are busy and buildings without an arrangement may wait. Water extraction, drying support and sanitizing affected floors should be described in the contract or an addendum.
