Office building unblocking in Belgium

In an office building, blockages come from two places almost every time: the shared washroom block on the floor, where paper towels end up down the pan, and the kitchenette or coffee corner, where coffee grounds and food scraps go into a small-bore pipe. Neither stops the business, but both hurt comfort and productivity across a whole floor. Van Dijk Home works outside office hours, in agreement with the facilities manager, to limit disruption and hand the floor back cleanly.

Office building unblocking: drain pipework in a plant room

Our approach

A method built around office hours

Moving fast does not mean disturbing teams. Van Dijk Home follows steps that locate the cause, clear cleanly and hand the floor back with minimal disruption.

  1. 01

    Coordination

    We go over the floors and washroom blocks concerned with the facilities manager, the access routes and the windows when no workstation is affected. This initial coordination frames the visit without disturbing the day's activity.

  2. 02

    Targeted diagnosis

    On site we test the block's sanitary fittings and the floor kitchenette to locate the blockage: local trap, floor collector or shared pipe between levels. We choose the technique once the cause is located, not before.

  3. 03

    Clearance without damage

    We remove what is obstructing the pipe (paper towels, coffee grounds or grease build-up) with equipment suited to built-in pipework and office finishes. Floors, partitions and sanitary ware stay protected throughout.

  4. 04

    Check and prevention

    We test every fitting in the block and the kitchenette, flush the floor collector through and set out simple measures (strainer, signage, periodic maintenance) that limit repeats. A report can be handed to the facilities manager for follow-up.

Outside office hours

Work while the offices sleep

We favour evening, early-morning or weekend slots when the facilities manager considers that a better fit. The floor is empty, open-plan areas are not taken over by equipment and teams find working washrooms on arrival, without crossing a work site.

That planning needs preparation: access, passes, service lifts, safety rules. Van Dijk Home prepares this with the facilities manager so nothing is improvised on site and the building rules are respected.

When urgency will not wait, we reduce the footprint to the strict minimum: fenced area, discreet equipment, targeted work on the blocked point. The aim stays the same: restore flow without turning a floor into a visible construction site.

Shared blocks and kitchenettes

Why offices block differently from homes

An office floor concentrates sanitary use on one shared block: several toilets, urinals and basins run into the same collector. Paper towels, thrown down pans out of habit, form knots that water does not dissolve. Add the kitchenette or coffee corner, where fine coffee grounds and lunch scraps feed a small-bore pipe, often undersized for heavy use.

Unlike a private home, nobody 'owns' the washroom block: responsibility is diffuse and bad habits accumulate without the user seeing the consequences. A build-up in the floor collector can slow several fittings at once, sometimes several levels if pipes tie together vertically.

The facilities manager mainly wants disruption kept down. Van Dijk Home therefore works outside office hours when that is often a better fit, treats block and kitchenette together since they usually share one collector, and offers a preventive contract to avoid repeats.

Around this issue

Offices, and what goes with them

A blockage in an office building often leads to other services depending on whether the fault is at the toilet, kitchenette or collector. Here are the most useful links.

Signals to watch

When to alert facilities or Van Dijk Home

These symptoms often point to a blockage at the floor collector rather than a single isolated toilet. Acting early limits disruption for teams.

  • Several fittings in the same block drain slowly at the same time.
  • The kitchenette sink backs up though nobody has changed their habits.
  • An odour lingers in the washrooms despite regular cleaning.
  • One floor's washroom block fails while other floors are fine.
  • Gurgling appears when several people use the washrooms in succession.
  • The blockage hits during a period of heavy floor occupancy.

While you wait for us

What to do before we arrive

A few simple steps limit disruption for teams and make our work on the floor concerned easier.

  1. 01

    Close the washroom block if possible

    Post a temporary notice and direct teams to another block on the same or a neighbouring floor.

  2. 02

    Stop using the kitchenette

    Do not use the sink or coffee machine: every extra litre feeds an ongoing backflow.

  3. 03

    Alert the facilities manager

    Confirm access, the agreed window and who will open technical rooms for us if needed.

  4. 04

    No chemical drain cleaner

    Aggressive products do not open a fouled collector and can damage finishes. Wait for our diagnosis.

Transparent pricing

What determines the price

Our call-outs start from €72.60 incl. 21% VAT (non-residential premises).

The price depends on where the blockage sits (isolated sanitary fitting, kitchenette or floor collector) and the technique required. We assess on site, announce the final price before starting and detail what is included, including a report for the facilities manager.

For office buildings we also offer preventive maintenance contracts by floor or building, often more cost-effective than a run of emergency calls. Contact us for a quote matched to your occupancy.

How much does office building unblocking cost?

Our call-outs start from €72.60 incl. 21% VAT (non-residential premises). The price depends on where the blockage sits (isolated sanitary fitting, kitchenette or floor collector) and the technique required.

Do you really work outside office hours?

Yes. We schedule in the evening, early morning or at the weekend when the facilities manager considers that appropriate. The floor is empty, teams are not exposed to noise or equipment, and washrooms work again on arrival.

Why do shared washroom blocks clog so often?

Because several people use the same toilets and basins without individual upkeep. Paper towels down pans and wrongly flushed items form blockages water does not dissolve. Everything runs into the same floor collector, which eventually fouls.

Do kitchenette sinks really matter for office blockages?

Yes, often as much as the washrooms. Fine coffee grounds, lunch scraps and grease go into a small pipe, often shared with other outlets on the floor. A sink that drains slowly is a signal not to ignore.

How do you limit disruption during the work?

We fence the area, protect floors and finishes, use equipment as discreetly as possible and favour slots outside occupancy. When daytime urgency cannot wait, we keep the footprint down to the strict minimum.

Do you offer preventive contracts for office buildings?

Yes. Periodic maintenance of collectors and washroom blocks reduces emergencies in the middle of the working week. We set a clear framework (frequency, access, price) matched to the building's size and occupancy.

Can one blockage hit several floors?

Yes, if pipes from several levels tie vertically into the same main collector. A build-up on one floor can slow every fitting on that level, and sometimes affect the floor below as water seeks an outlet.

When should you call a drain technician straight away?

Some signs mean the blockage is no longer local: waste water backing up into a shower, sink or toilet, several fixtures draining slowly at the same time, water rising from a yard gully, or a sewer smell that lingers despite ventilation. In those cases, avoid reaching for chemical drain cleaners again and again: they attack seals and pipework without reaching a blockage further down the run.
