Thermal Imaging Inspection in Carcavelos

About our service in Carcavelos

Rain driven by the wind behaves quite differently from rain that falls straight down. It finds fine cracks in the render, sill joints, frame junctions and points where a pipe or a bracket passes through the wall, and it is pushed inwards under pressure. Once inside, the water spreads through the render before it shows itself, which is why the visible patch often sits a metre or two from the point of entry. In a thermal image, a wet wall evaporating reads colder than the dry wall around it, and the shape of that cold zone usually points back to the source. We inspect from inside and, wherever access allows, from outside on the same elevation. The timing of the visit matters a great deal. Around here the best results come shortly after a spell of wind and rain, while the wall is still drying, and not weeks later with everything settled. We work room by room, with the home closed up and heated or cooled beforehand, compare the exposed elevation with a sheltered one on the same building, and record thermogram and photograph in matching framing. Suspect points are confirmed with a contact moisture meter. In the rented flats by the beach and in Sassoeiros, the report often serves to establish between owner and building management whose part of the façade is at issue. What should not be expected of thermography is a guaranteed result. If there is no temperature difference between the wet zone and the dry one, the image shows nothing useful, and that happens on mild days with walls that have already dried. The camera does not see through render and does not measure moisture; it reads surface temperature, which is why conclusions are always cross-checked with the contact meter and with the history of the property. When doubt is left, the right answer is to open up at one point, not to make an assertion.
