Frequently

Each visit includes three components: cleaning and removal of debris from rooftop drain grates and downpipe entry points; mechanical or hydraulic unblocking where needed to restore full flow; and camera inspection of each downpipe to document internal condition. After the visit, a written report is provided detailing findings per pipe and recommending a maintenance frequency for the building.

Duration depends on the building's size — specifically the number of downpipes, building height, and the condition of the pipes. We assess these factors during the initial consultation before scheduling the visit, so we can provide an accurate time estimate for your specific building.

In most cases, no. The work is carried out from the rooftop and from building service areas. Residents in their apartments are generally not affected. If access to a specific apartment is needed due to a particular pipe configuration, the consortium is informed in advance so arrangements can be made.

The report documents each downpipe individually. For each pipe, it describes the internal condition observed during camera inspection — sediment levels, any cracks or deformations, presence of root intrusion, and joint condition. It also identifies any anomalies that may require attention beyond routine cleaning, and provides a recommended maintenance frequency for the building based on its specific context (tree coverage, pollution level, pipe age and type).

Yes. In fact, this is a common situation. Cleaning is performed first to restore flow and remove loose debris, which then allows the camera to pass through and document the pipe's internal condition accurately. The inspection after cleaning gives a clearer picture of the pipe wall condition than inspection through debris would.

There is no single answer that applies to all buildings. Frequency depends on factors specific to the building's location and environment: the density and species of surrounding trees, local air pollution levels, the age and material of the pipes, and the building's drainage layout. The inspection report provides a recommendation tailored to these factors for your specific building.

Leaves, seeds, bark fragments and other organic material from trees are the primary source of debris in rooftop drains and downpipes. Buildings surrounded by mature deciduous trees — which shed leaves seasonally — accumulate organic debris much faster than buildings in open urban blocks with minimal tree coverage. The species of trees also matters: some produce seeds or fruits that create particularly dense blockages.

The finding is documented in the written report with a clear description of what was observed and its location within the pipe. The report also describes the general remediation options relevant to the type of issue found. The consortium then has the information needed to decide how to proceed — whether to address the issue immediately, monitor it at the next inspection, or consult a specialist for further assessment.

This is the central purpose of preventive maintenance. By the time a leak becomes visible inside an apartment, the blockage or pipe failure has usually been developing for some time. Inspection identifies developing conditions before they cause visible damage — which is when intervention is simpler and the consequences are less severe.

Contact Loxnudi by phone, email or through the contact form on this site. Provide basic information about the building — address, approximate number of floors and downpipes if known — and we will arrange an initial consultation to assess requirements and schedule the visit.

Useful information includes: the building's address, the approximate number of floors, whether the building has had drain cleaning performed previously and when, any known drainage issues or recent leak incidents, and whether there are restrictions on rooftop access. This helps us prepare appropriately and provide an accurate time and resource estimate.
