Janitorial Service Glossary: 25 Terms Every Portland Business Owner Should Know

You have been reading cleaning proposals for weeks and you still do not know what a scrub-and-recoat actually costs or why your provider keeps talking about dwell times. The cleaning industry uses a lot of jargon, and it is not always intentional — sometimes the people writing the proposals just assume everyone knows what they mean. This glossary fixes that.

Core Janitorial Terms

Janitorial Services

Facilities maintenance cleaning — the category that covers offices, warehouses, medical facilities, schools, and commercial spaces. Janitorial is environment-centered (the space, not the person in it) and operates on documented scopes, quality inspections, and compliance frameworks. This is different from housekeeping, which is person-centered and hospitality-focused.

Housekeeping

Hospitality-oriented cleaning — hotels, senior living, short-term rentals. Housekeeping operates around the rhythms of the people in the space. It does not include the compliance documentation, quality inspections, or regulatory frameworks that commercial janitorial requires. If you own a Portland business and someone offers you housekeeping services, they are probably not the right fit.

Scope of Work (SOW)

The written document that defines exactly what your cleaning provider will do — and what they will not do. A proper SOW includes service frequency, specific tasks covered, products used, quality standards, and reporting structure. If a cleaning company quotes you without a written SOW, you are getting a guess, not a commitment. For Portland businesses in Tigard, Beaverton, and Lake Oswego, a written SOW is the baseline expectation for any commercial contract.

Frequency

How often the cleaning crew comes — nightly, three nights per week, weekly, etc. Higher frequency means higher cost, but it also means your space stays cleaner and soil does not accumulate between visits. Portland offices typically need 3-5 nights per week. High-traffic facilities (call centers, co-working spaces, downtown buildings) may need nightly service.

Square Foot Pricing

The standard way janitorial companies price commercial contracts. The provider multiplies your building square footage by a per-square-foot rate that reflects service frequency and scope complexity. For Portland commercial spaces, rates typically range from $0.05-$0.15 per square foot per visit depending on traffic level, industry requirements, and building conditions.

Cleaning Tasks and Techniques

High-Touch Surface Disinfection

Targeted cleaning of the surfaces that harbor the most pathogens because they are touched most frequently: door handles, push plates, light switches, elevator buttons, handrails, faucet handles, and shared equipment. Post-pandemic, high-touch surface disinfection is a baseline expectation — not an add-on. Ask any Portland cleaning provider what products they use and verify they are EPA-registered for enveloped viruses.

Dwell Time

The amount of time a disinfectant must remain wet on a surface to achieve full disinfection. If a product requires two minutes of dwell time and you wipe it dry after 30 seconds, the surface was not actually disinfected. Dwell time is one of the most commonly skipped steps in under-trained cleaning crews — and one of the most important for infection control in medical and dental offices.

Scrub-and-Recoat

A VCT floor maintenance cycle where the existing finish is deep-scrubbed (using a floor buffer with appropriate pad) and then refreshed with 1-2 fresh coats of finish. This restores the shine without full stripping. For Portland offices in older buildings, a quarterly scrub-and-recoat extends floor life substantially.

Strip-and-Wax

A full floor restoration where all existing finish is removed (using chemical stripper) down to the bare tile, and fresh coats of finish are applied from scratch. Strip-and-wax is labor-intensive and disruptive — it should only happen when scrub-and-recoat cannot restore the floor. Many property managers in Beaverton pay for unnecessary full strips because they did not understand the scrub-and-recoat option.

Hot Water Extraction

The gold standard for commercial carpet cleaning. Heated water (180-200F) is injected into the carpet pile under pressure, suspending soil in moisture, then extracted with strong vacuum. Removes embedded particulate, oily soils, bacteria, and allergens that surface vacuuming cannot reach. Also called steam cleaning in consumer marketing — though no steam is actually used.

Encapsulation

A low-moisture carpet cleaning method where a chemical is worked into the pile and dried to a crystalline residue that encapsulates dirt particles, which are then vacuumed away. Minimal drying time (carpet back in service within an hour), no moisture risk to backing or pad. Good for maintenance cleaning between deep extractions, but does not replace hot water extraction for restorative work.

Auto-Scrubbing

Using a walk-behind floor scrubber (battery-powered machine with rotating brushes) to clean hard floors. More effective and faster than manual mopping. Standard practice for VCT corridors, concrete warehouse floors, and ESD flooring in server rooms. Auto-scrubbers should be used with neutral pH cleaners — acidic or alkaline products damage floor finish.

High Dusting

Cleaning of surfaces above eye level — ceiling vents, tops of partition walls, overhead light fixtures, tops of door frames, structural steel. High dusting is often skipped because it is not at eye level — and it accumulates for months before anyone notices. For Lake Oswego offices in older buildings with limited ventilation, high dusting has a measurable impact on indoor air quality.

Dust Mopping

Using a treated dust mop (not a wet mop) to remove loose dirt and grit from hard floors. The most important daily maintenance task for VCT — grit acts like sandpaper underfoot and destroys wax finish faster than foot traffic. Dust mopping should happen every night in high-traffic entry areas, especially during Portland wet season (October-April).

Entryway Matting

Indoor and outdoor floor mats placed at building entries to capture soil, moisture, and grit before they reach interior flooring. Industry data shows quality matting captures 60-80% of tracked-in soil. In Portland, entryway mat maintenance is not optional — it is the first line of defense against wet-season carpet damage. Mats should be vacuumed daily during October-April and cleaned or replaced when saturated.

Compliance and Safety Terms

EPA-Registered Disinfectant

A cleaning product registered with the Environmental Protection Agency as effective against specific pathogens. Hospital-grade disinfectants used in medical and dental environments must be EPA-registered for enveloped viruses. The EPA assigns a registration number (Reg. No.) that appears on the product label. Always ask your cleaning provider for the specific products they use and verify the EPA registration.

Bloodborne Pathogens (BBP) Training

Required training under OSHA standard for anyone who may be exposed to blood or bodily fluids in the workplace. Cleaning staff in medical facilities, dental offices, schools, and fitness centers need BBP awareness. Any Portland cleaning provider working in a dental office or medical environment should be able to document BBP training for their staff.

Safety Data Sheet (SDS)

A standardized document that describes the chemical properties, hazards, handling procedures, and emergency response information for a cleaning product. Your cleaning provider must maintain SDS sheets accessible to your staff for all products used in your building. This is an OSHA requirement in most commercial settings.

Green Cleaning

Cleaning practices and products that reduce chemical exposure, minimize environmental impact, and improve indoor air quality. In Portland, eco-friendly cleaning products are increasingly expected — especially in older buildings with limited ventilation. Look for products certified by EPA Safer Choice, Green Seal (GS-8, GS-37), or ECOLOGO.

OSHA General Duty Clause

The Occupational Safety and Health Administration requires employers to maintain a workplace free from recognized hazards. For cleaning purposes, this means standing water, unmarked spills, and accumulated debris are citation risks. Your cleaning provider is directly responsible for identifying and addressing these hazards during each service visit.

Contract and Service Terms

Quality Inspection

A documented review of the cleaning service performed by a supervisor — typically weekly or monthly depending on contract size. A quality inspection should include a written checklist, a walkthrough of the facility, and documentation of any deficiencies. If your cleaning provider does not offer documented quality inspections, you have no way to verify the scope is being delivered.

Service Issue Resolution

The process for handling complaints, missed services, or quality failures. Before signing a contract, ask specifically: what happens if a service visit is missed? How do I report a problem? What is the response time? A company without a clear escalation path is not structured to maintain quality consistently.

Dedicated Team vs. Route Crew

Dedicated teams are assigned to your building and learn your space, your schedule, and your standards. Route crews move between multiple buildings each night — the crew that cleans your office today may be in a different building tomorrow. For Tigard businesses with specific cleaning requirements, a dedicated team delivers more consistent results.

Markup or Mark-Up

The percentage added to the cost of cleaning supplies and materials. Some contracts include a markup on products; others include products in the base price. If a cleaning company is vague about how products are priced, ask specifically — markup percentages on consumables can add 10-20% to your monthly contract cost.

Pass-through Costs

Costs that are passed through to the client at actual cost without markup — typically consumables (toilet paper, paper towels, hand soap), waste disposal fees, or specialized equipment rental. A transparent cleaning company will show you pass-through costs separately from labor and overhead.

Term Contract

A cleaning contract with a defined duration — typically 1 year or multi-year. Most commercial cleaning contracts are structured as annual term agreements with month-to-month renewal after the initial term. The contract should specify cancellation terms (usually 30 days written notice) and any early termination fees.

Certificate of Insurance (COI)

A document proving a cleaning company carries general liability and workers compensation insurance. Ask for a COI and verify it has not expired before signing any contract. The coverage amounts you should expect: general liability $1M+ per occurrence, workers compensation as required by Oregon law. A company that cannot produce a COI in 24 hours does not carry the coverage they claim.

Scope Expansion

Additional services added to the original contract — new cleaning zones, increased frequency, specialty services. Any scope changes should be documented in writing with updated pricing before the work begins. Be wary of providers who add scope informally without updating the contract — this creates billing disputes and service inconsistencies.

Knowing the Terms Protects Your Business

Reading cleaning proposals is easier when you know the vocabulary. A provider who uses these terms precisely is demonstrating actual industry knowledge — not just a sales script. And when you understand the terms, you can ask the right questions: Is this scrub-and-recoat or full strip? What is the dwell time on the disinfectant? Who is the dedicated crew? What does the quality inspection look like?
