Corporate Event Cleaning in the Office — Pricing and Case Study 2026

Case Study: Office Cleaning 300 m² After a Corporate Event for 50 People

In March 2025, the Reefa team handled cleaning after an integration event in one of Cracow's technology company offices. The 300 m² facility — an open space with three conference rooms, a kitchenette, reception area, and a relaxation zone — hosted 50 employees during a Friday evening corporate event.

The event included catering (finger food, warm dishes at a station, dessert bar), an alcohol bar (wine, beer, cocktail station), and a networking zone with high-top tables. End time: 23:00. Our team started work at 23:30 to ensure the office functioned normally by Monday morning (the event was on Friday).

Scope of Work Completed

The four-person Reefa team performed the following actions:

Event Area (open space + conference rooms):

• Removal of red wine stains from carpeting in the conference room (three larger stains required enzymatic stain removal)
• Collection and sorting of waste — 12 bags of 120 l capacity (glass, plastic, organic waste, paper)
• Emptying of 15 temporary bins set up for the event
• Vacuuming of all floor surfaces, including hard-to-reach areas under cocktail tables
• Mopping of hard floors using the two-bucket method

Kitchenette:

• Cleaning of countertops and sinks after catering
• Refrigerator cleaning (leftover food, spilled beverages)
• Cleaning of induction hob and oven (used by catering)
• Surface disinfection in accordance with HACCP procedures

Restrooms:

• Comprehensive cleaning of 4 stalls and wash basins (increased usage during the event evening)
• Restocking of paper, soap, and towels
• Disinfection of door handles, flush buttons, and faucets

Additional Tasks:

• Removal of bottles and alcohol-related packaging to appropriate containers
• Cleaning of glass surfaces (fingerprints on conference room glazing)
• Airing of rooms and restoration of standard furniture arrangement

Response Time and Schedule

Speed of response after an event determines the comfort level of employees returning to the office. In our case study, we applied a "night intervention" model:

• 23:30 (Friday) — cleaning team arrival
• 01:45 (Saturday) — completion of work in open space and conference areas
• 03:00 (Saturday) — finalization of kitchen and restroom cleaning, quality control
• 03:30 (Saturday) — photo report sent to office manager

For events ending late in the evening (after 22:00), we recommend intervention the same evening or early morning (start 5:00–6:00). For afternoon events (end time 17:00–19:00), intervention directly after guest departure is possible, which shortens execution time and often allows for a smaller team (2–3 people instead of 4).

Our company has operated in Cracow since 2020 and in Katowice since 2024 — each facility has a dedicated coordinator who schedules post-event cleaning in consultation with the office manager.

How Much Does Cleaning After a Corporate Event Cost?

The cost of post-event cleaning depends on four main variables: office area, number of guests, scope of work, and cooperation model (one-time service versus standing agreement).

Pricing for Case Study (300 m² office, 50 people, event with catering and alcohol)

One-time engagement (no standing office cleaning agreement):

• Team of 4 people, ~5.5 hours of work
• Cost: 1000–1200 PLN net
• Includes: standard post-event scope, basic cleaning supplies, waste sorting, removal of simple stains

As Part of a Standing Office Cleaning Agreement:

• Team of 4 people, ~5.5 hours of work
• Cost: 600–700 PLN net (40–50% less)
• Includes: expanded scope, dedicated stain-removal products, on-site coordinator, photo report, liability insurance up to 1,000,000 PLN

Cost Table by Event Size (net prices, 2026)

Prices include team travel within Cracow or Katowice, basic cleaning supplies, and waste sorting and disposal for standard waste streams. Additional services — upholstery cleaning, professional removal of difficult stains (e.g., grease, sauce), specialist disinfection — are priced individually.

If your company plans cyclical events (e.g., quarterly team-building meetings, monthly all-hands), consider expanding your office cleaning agreement in Cracow or Katowice to include an event package. In our case, clients with standing agreements receive not only a lower rate but also priority access to teams on weekends and public holidays.

Key Challenges: Stains, Crumbs, Waste Sorting

Every corporate event generates specific cleaning challenges. In practice, three categories of soiling determine the time and cost of intervention.

Alcohol and Food Stains

Red wine, colorful cocktails, sauces, grease from finger food — these are the most common causes of difficult stains on carpets, upholstery, and floors. In our case study, two red wine stains on the conference room carpet required the use of enzymatic detergents and four rounds of treatment. Total work time on these stains: 45 minutes per person.

Best Practices:

• Immediate intervention (the shorter the gap between spillage and cleaning, the greater the effectiveness)
• Enzymatic products for organic stains (wine, coffee, juice)
• Testing on an inconspicuous carpet area before applying the product to the main stain

Our team works exclusively with products bearing EU Ecolabel certifications or equivalent, guaranteeing safety for office users and minimizing the risk of material damage.

Crumbs, Food Residue, Packaging

An event with catering means hundreds of disposable containers, food remnants in the least expected places (behind furniture, in plant pots, on windowsills), and crumbs requiring thorough vacuuming. In our case study, we collected 12 bags of waste — six times the daily waste output from the same office.

It is crucial to apply sorting in accordance with local waste management systems — in Cracow and Katowice, a five-stream system applies (plastic/metal, paper, glass, bio, mixed). Our team uses color-coded bags and labels to avoid errors when handling large quantities of waste.

Intensive Use of Common Areas

Restrooms, kitchenettes, corridors — these zones after an event require refreshing hygiene standards. In the case study, we observed:

• Consumption of 3x more toilet paper and paper towels than on a typical day
• Need to clean refrigerators (catering left behind remnants in reusable containers)
• Fingerprints on all glass surfaces (room glazing, doors, counters)

Reefa's standard is to apply disinfection to high-touch surfaces (door handles, light switches, railings) after every event — this is part of our HACCP-compliant protocol for spaces with catering.

Team and Equipment: What Is Needed for Effective Cleaning?

The efficiency of post-event cleaning depends not only on the number of people but also on team competence and access to specialized equipment.

Team Composition

In our case study, 4 people worked:

• 1 coordinator (schedule oversight, client communication, quality control)
• 3 operators (task division: event zones, kitchen + restrooms, waste removal, and finishing work)

For offices up to 150 m² and events of up to 30 people, a team of 2–3 people is sufficient. Above 500 m² and 100 guests, we recommend a team of 6+ to maintain a 6–8 hour window (night or early morning work).

All operators in the Reefa team undergo health and safety training, are legally employed and insured, and their competencies include:

• Recognition of surface types and selection of appropriate products
• Safety procedures when working with professional chemicals
• Waste sorting and basic GDPR awareness (privacy in office spaces)

Equipment and Cleaning Supplies

Essential Equipment for an Event in a 300 m² Office:

• Industrial vacuum with HEPA function (filters fine particles, dust from events)
• Flat mop + two-bucket system (hard floor cleaning without streaks)
• Carpet/upholstery cleaning equipment (hot water extraction for stains)
• Service cart with color-coded waste bins
• Color-coded microfiber cloths (separate colors for restrooms, kitchens, office areas)

Cleaning Products:

• Enzymatic detergents for organic stains
• Glass cleaning products (elimination of streaks on glazing)
• Disinfectants compliant with EN 14476 standards (virucidal)
• Odor-neutral air fresheners (no allergenic fragrances)

Our team arrives with a complete set — the client does not need to provide equipment or supplies. Liability insurance up to 1,000,000 PLN covers any potential damage arising from the work.

Checklist: How to Plan Cooperation with Your Cleaning Company Before an Event?

Effective post-event cleaning begins at the event planning stage. The following checklist will help you avoid surprises and ensure smooth cooperation with your cleaning company.

7–10 Days Before the Event

☐ Establish Event Details:

• Expected number of guests
• Type of catering (finger food, warm dishes, alcohol bar, dessert bar)
• Event end time
• Office zones that will be used

☐ Agree on Scope of Work:

• List of rooms to be cleaned
• Flooring and furniture materials (carpet, panels, parquet, upholstery)
• Special requirements (e.g., certified eco-friendly products, building quiet hours)

☐ Get a Quote and Confirmation:

• Detailed quote (preferably in writing)
• Confirmation of team availability on your chosen date (especially important for weekends)
• Agreement on payment method and settlement terms

2–3 Days Before the Event

☐ Provide Access:

• Keys/access cards for the cleaning team
• Alarm codes, building lockdown instructions
• Contact for on-duty person (office manager, security)

☐ Waste Logistics:

• Location of sorted waste containers
• Information on any restrictions for waste removal in the building (time slots, freight elevators)

☐ Internal Team Communication:

• Inform employees about the event and planned cleaning
• Request to secure valuables (documents, electronics) in locked cabinets

Event Day and Intervention

☐ Contact the Cleaning Company Coordinator:

• Confirm the team's arrival time
• Inform of any changes (e.g., earlier event end)

☐ Acceptance of Work:

• Photo report of completed work (standard for Reefa after each engagement)
• Quick inspection of key areas (conference rooms, kitchen, restrooms)
• Settlement and feedback

If your office has a standing cleaning agreement, the facility coordinator already knows the specifics of the space, which shortens planning time and eliminates the risk of misunderstandings. For clients such as Ottobock or TWW, our company maintains detailed facility documentation, allowing immediate response to ad-hoc events.

Post-Event Cleaning vs. Standing Agreement — Why It's Worth It

One-time engagements are a solution for companies that organize events sporadically (once or twice a year). However, if your company plans regular team-building meetings, conferences, training with catering — expanding your standing agreement to include an event package generates measurable benefits.

Cost Savings

As shown in the pricing section, standing agreement clients pay 40–60% less for post-event intervention. Example: four events annually in a 300 m² office:

• One-Time Engagements: 4 × 1100 PLN = 4400 PLN net/year
• Under Standing Agreement: 4 × 650 PLN = 2600 PLN net/year
• Savings: 1800 PLN net annually

Schedule Priority

Cleaning companies plan their schedules weeks in advance. With a standing agreement, your events receive priority status — even notification 48 hours before an event (instead of the standard 7–10 days) has a good chance of being accommodated, as the coordinator knows your facility and can shift resources.

Consistency of Standards

The same team that cleans your office daily knows the space best: which carpets are sensitive to alkaline detergents, how to handle the alarm, where waste containers are located. In our case study, the team began work at 23:30 without the office manager present — they had all necessary information and access.

Additional Services in the Package

A standing agreement with Reefa includes:

• Dedicated facility coordinator (24/7 phone availability for urgent issues)
• Photo reports after each cleaning (access via app or email)
• QR-based reporting for current issues (employees can report cleanliness concerns in real time)
• Liability insurance up to 1,000,000 PLN

Thanks to our 91% client retention rate, we can confirm that the standing agreement model with event options is the most frequently chosen solution among our corporate clients.

Specifics of Cleaning After Different Types of Corporate Events

Not every event generates the same cleaning challenges. Here's an overview of the most common formats and their impact on scope of work.

Team-Building Event with Alcohol and Catering

Highest risk of stains and intense soiling. Typical scope:

• Removal of alcohol stains (wine, cocktails, beer)
• Upholstery and carpet cleaning
• Removal of large quantities of glass and plastic packaging

Time: 4–6 hours for 300 m² | Team: 3–4 people

Conference/Training with Lunch

Moderate soiling risk, mainly in the catering area and restrooms. Typical scope:

• Vacuuming of the conference room
• Kitchen cleaning after lunch boxes
• Waste removal (paper, cardboard packaging)

Time: 2–3 hours for 300 m² | Team: 2–3 people

Networking/Meeting Without Catering

Lowest risk, mainly space refreshing. Typical scope:

• Basic vacuuming and floor mopping
• Restroom cleaning
• Trash emptying

Time: 1–2 hours for 300 m² | Team: 2 people

For special events — internal trade fairs, company galas, product events — we recommend individual quotes, as the scope may include additional elements (e.g., cleaning of exhibition stands, removal of promotional materials, cleaning of roll-up banners).

The Reefa team also collaborates on event cleaning in Cracow, including external event venues outside offices — more information is available directly via contact with us.

Legal Aspects and Health & Safety in Post-Event Cleaning

Every cleaning intervention in an office space carries legal responsibility — both for the cleaning company and the client.

Insurance and Liability

A cleaning company should have liability insurance at a minimum of 500,000 PLN. At Reefa, we guarantee coverage up to 1,000,000 PLN, which protects against consequences of potential damage (e.g., equipment damage during work, upholstery damage from improper products).

Before signing an agreement, verify:

• A copy of the cleaning company's liability insurance policy
• Territorial scope (the policy must cover the service location)
• Exclusions from liability (some policies do not cover damage during night work)

GDPR and Data Protection

Office cleaning — especially after hours — means team access to spaces with potentially sensitive data (documents on desks, computer screens, noticeboards with notes). A professional cleaning company should:

• Sign a data processing agreement (if access to personal data is unavoidable)
• Train the team on confidentiality and prohibition of photographing the client's space (except for agreed photo reports)
• Apply check-in/check-out procedures (confirmation of entry and exit from the facility)

Our team undergoes annual GDPR training, and each facility coordinator signs a confidentiality clause.

Safety During Night and Weekend Work

Work during night hours (23:00–6:00) and weekends is subject to specific health and safety regulations. A cleaning company should provide:

• Appropriate lighting in the work area (portable lamps if necessary)
• Access to first aid (first aid kit, contact with on-duty person)
• Evacuation procedures (familiarity with emergency exits, building evacuation plans)

In our standards, every team working at night or on weekends has direct contact with the facility coordinator and building security. This minimizes the risk of incidents and ensures rapid response in emergencies.

Frequently Asked Questions

How much does a cleaning company charge per hour?

The cost per hour of work for a cleaning company during a corporate event in Cracow and Katowice is 45–60 PLN net per person for one-time engagements and 25–35 PLN net per person under standing agreements. The difference stems from schedule optimization, elimination of client acquisition costs, and the team's familiarity with the facility. For a typical event in a 300 m² office (team of 4, 5 hours), the total cost is 1000–1200 PLN net one-time or 600–700 PLN net under a standing agreement. You can obtain an exact quote for your office via our online calculator or by direct contact with our team.

What is the cleaning hourly rate in 2026?

In 2026, hourly rates for event cleaning in the B2B segment range from 45 to 60 PLN net per person for one-time engagements and from 25 to 35 PLN net per person under long-term standing agreements. Cost depends on event type (with alcohol and catering vs. meeting without food service), location (Cracow, Katowice), team availability (weekend/night vs. business day), and scope of specialist work (e.g., difficult stain removal). Our team works with legally employed and insured operators, guaranteeing compliance with labor law and your facility's safety.

How long does office cleaning take after a corporate event?

Post-event office cleaning time depends on area, number of guests, and soiling level. For a 150 m² office after a 30-person event, typical time is 3–4 hours (team of 2–3). A 300 m² office after a 50-person event requires 4–6 hours with a 3–4 person team. Facilities over 500 m² with events for 100+ guests — 6–8 hours with a 4–6 person team. In the case study described in the article (300 m², 50 guests, catering, alcohol), the four-person Reefa team completed the work in 5.5 hours, starting at 23:30 and finishing at 3:30. It is crucial to schedule cleaning so the office is ready before employees return.

Can a cleaning company intervene the same evening after the event?

Yes, professional cleaning companies offer same-evening or early-morning intervention. At Reefa, we have standby teams that can start work immediately after the event ends (even after 23:00). Such a model is especially popular for Friday events — night cleaning allows the office to be fully ready by Monday morning. This requires prior schedule agreement (ideally 7–10 days before the event), providing access to the facility, and confirming team availability during night hours. Clients with standing agreements have priority access to evening and weekend interventions, even with 48-hour notice.

What should be agreed with the cleaning company before a corporate event?

Before a corporate event, establish: (1) detailed scope of work (which rooms, types of soiling, special requirements like eco-friendly products), (2) schedule — cleaning start and end time, (3) team size and estimated completion time, (4) price and payment method (standing agreements often settled within monthly invoices), (5) access logistics (keys, alarm codes, on-duty contact), (6) work acceptance method (photo report, personal inspection), (7) cleaning company's liability insurance. We recommend starting discussions 7–10 days before the event, allowing time to finalize details and confirm team availability. Our team provides a dedicated coordinator who guides you through the entire planning process.

What cleaning products are best for removing stains after an event?

For removing stains after a corporate event, enzymatic detergents dedicated to organic stains are most effective — wine, coffee, juice, food grease. Enzymes break down organic particles at the molecular level, enabling complete stain removal without damaging carpet fibers or upholstery. For hard surfaces (panels, parquet), pH-neutral detergents are used, which do not damage protective coatings. For grease stains, alkaline products are effective but require thorough rinsing. The Reefa team works exclusively with products bearing EU Ecolabel or equivalent certifications, guaranteeing safety for office users, minimizing allergy risk, and aligning with the ESG policies of many corporate firms. Before applying any product to a visible surface, we test it on a hidden area of the material.
