Damp in Paraguayan houses is one of the most honest complaints there is: a wall that weeps, a wardrobe that smells, a ceiling that stains. Sometimes it is a site error. Sometimes it is a lot that will not drain. This piece does not sell a miracle product. It orders causes a client can ask about before the fungus reaches the family chat.

Key points

  • First the water that enters, not the paint that hides it: Blocked gutters, a bad slab junction, a patio falling the wrong way, a tap dripping toward the wall.
  • The lot and the slab: damp that rises: Low land, poorly compacted fill, missing barrier, stormwater sitting against the wall.
  • Roof, eave and a storm at midday: A leak does not always look like a film.
  • Ventilate, do not only cool: Very glazed contemporary houses, no cross-breeze, blind bathrooms and wardrobes on cold walls: vapour stays.
  • What to ask on a visit and at pre-handover: Where stormwater leaves, how the gallery junction is done, what happens in the windowless bathroom.

First the water that enters, not the paint that hides it

Blocked gutters, a bad slab junction, a patio falling the wrong way, a tap dripping toward the wall. Before talking about “rising damp” as a myth, walk the house the day after rain. Painting a symptom is October’s temptation. Fixing the entry of water is craft. If the team only offers a paint hand, ask what was investigated.

First the water that enters, not the paint that hides it — Wall and floor junction detail in a humid climate

The lot and the slab: damp that rises

Low land, poorly compacted fill, missing barrier, stormwater sitting against the wall. Ask street level versus house level, and how water leaves the plot. On a lakeside residence, the handsome landscape and wet soil coexist. The design has to choose junctions that can dry.

Roof, eave and a storm at midday

A leak does not always look like a film. Sometimes it stains a corner two days later. If there is a ceiling stain, do not start with filler. Start above, with someone who climbs. Ask for the diagnosis in writing.

Ventilate, do not only cool

Very glazed contemporary houses, no cross-breeze, blind bathrooms and wardrobes on cold walls: vapour stays. A cool house is not a sealed house. If the brief includes a lot of storage, it must also say how those rooms breathe.

What to ask on a visit and at pre-handover

Where stormwater leaves, how the gallery junction is done, what happens in the windowless bathroom. At pre-handover, smell wardrobes and north corners. Damp is discussed early. Late, it is discussed with a roller in hand.
