DOCUMENTED PROJECT FROM DENMARK
Gentofte: repairing the render in an existing basement stairwell
A ventilation visit in Gentofte, Denmark, included a smaller masonry task: loose render was removed from an exterior basement stairwell, the sound background prepared and the surfaces repaired.

A limited repair to a retained staircase
The case shows a smaller improvement without constructing a new staircase. KÆLDER-RENOVERING states that the stair was retained while worn mineral surfaces were repaired. This differs from creating a new basement exit, which changes the opening, stair geometry and surrounding ground. Ventilation work brought the team to the property, but these three photographs do not document that installation.
Preparation is part of the visible sequence
The source describes removing loose render, cleaning and preparing the sound background, repairing damaged areas and applying a cement-based render. The early photograph shows exposed and repaired patches. The work photograph shows treatment of the steps while the walls already have a more continuous surface. The final view allows a comparison of the same stairwell after the surface work.
What the scope does not establish
The photographs document appearance. No specific mortar product, layer thickness, work date or background-moisture measurements are provided. A visible drain grating at the bottom also does not establish the drain's condition or capacity. We therefore describe a render repair, rather than treating the photographs as evidence that a water problem has been solved.
The project in photographs
Original photographs show the same stairwell during work and after the surface repair.

What to compare with your own project
- Distinguish a quotation for surface repair from one that also includes drainage work or structural changes.
- Take matching overview photographs before, during and after the work, plus close views where the background is exposed.
- Ask for the proposed preparation and render system to be identified in the quotation, along with any assumptions about moisture or frost exposure.
