Moisture Detection in Campo de Ourique

Arranja Já covers moisture detection in Campo de Ourique, from Prazeres and Santo Condestável across to the Amoreiras and the streets around the market. The neighbourhood is built mainly of walk-up blocks from the 1930s to the 1950s, and they share a very recognisable set of weak points: kitchens and bathrooms opening onto a narrow saguão, single-glazed windows in deep reveals, rear walls facing a shaded logradouro, and generations of paint and cement render on top of original plaster. Families here often live in the same flat for decades and watch the same patch come back every winter. We measure the moisture in the wall, establish which of the possible causes is really at work, and write it down.

About our service in Campo de Ourique

The internal lightwell is where a good many of these problems begin. A saguão is narrow, it sees little sun, and its walls are thin and cold. Bathrooms and kitchens vent into it, so the air is humid, and the render on those walls has usually been patched more than once. Result: mould on the inside face of the saguão wall, and a persistent damp band around the window. Sometimes that really is water entering through a failed gully or a cracked render outside; often it is condensation on the coldest wall in the flat. The distinction decides whether you need a builder or a change to the ventilation, so we measure rather than assume. The rest of the pattern is familiar in blocks of this age. Ground-floor flats and shops draw moisture up from below, and a tide of blistering paint appears at skirting level. Rainwater downpipes buried in the wall show up as a narrow vertical damp line that runs across several floors. Deep window reveals act as cold strips and grow mould in the corners of otherwise dry rooms. We record readings on each affected surface, compare them with sound plaster on the same wall, note the surface temperatures, and check the outside where the balcony or the street allows. Since a wall gives different values after rain than during a dry cold spell, we ask when the mark first appeared and, if the picture is genuinely ambiguous, we suggest a second reading in a different season. The report you keep gives the values, photographs, the origin we can defend and the steps in order. We diagnose only. A pipe losing water is work for our water leak repair service; a render, a waterproofing detail or a new gully belongs to our bricklaying team; and painting comes at the end, on a dry surface. Doing it the other way round is how the same patch returns for the fourth time.

Whatever the outcome, you receive the written report and the readings it rests on. If one visit leaves two plausible causes standing, we say which they are and what would separate them, instead of picking the more invasive one on your behalf.

Frequently Asked Questions

Questions we hear most often in Campo de Ourique:

The wall between my kitchen and the saguão is always black in the corner. Why there?

Because that corner is the coldest and least ventilated surface in a room that produces a lot of moisture. Humid air from cooking and washing meets a thin, shaded wall and condenses on it, and mould follows. The readings tell us whether the wall is soaked through, which would suggest water arriving from outside, or damp only at the surface, which points at ventilation and the cold face of the wall.

A thin vertical damp stripe runs down my hallway wall. What causes that shape?

That shape almost always follows something buried in the wall, most often a rainwater downpipe from the roof, sometimes an old waste stack. Water escapes at a joint and soaks the masonry around it, so the damp appears as a narrow band rather than a patch. We read across and along the line to find where the values are highest, which tells the builder where to open up rather than exploring the whole wall.

We are about to renovate a flat here. What should be measured first?

The rear and saguão walls, the ground-floor perimeter if you are on the lower levels, every reveal, and the ceilings under any terrace. Those are the places where hidden damp will ruin new finishes. Having the values before the works start also lets you sequence the trades correctly: cause first, drying time next, closing up and painting last.
