Once it dries, it seems to have disappeared\u2014until the next rain. The key isn\u2019t to guess where to make a repair based on the stain, but to piece together the clues that will help you find where the water is coming in.   <\/p>\n<p>This guide is intended for residents and property managers in Les Corts. It will help you describe the problem, know when to call, and understand what issues can be resolved through exterior work at heights. You don\u2019t need to know the name of every material to request an assessment.  <\/p><\/section><section id=\"vb-oct17-senales\" class=\"vo-reveal\"><h2>What the Water Is Telling You<\/h2><p>The location and timing of the water&#8217;s appearance guide the inspection.

Explain whether it affects one window or several homes. That comparison is usually more helpful than a close-up photo without any context.  <\/p><\/div><\/section><section id=\"vb-oct17-origen\" class=\"vo-reveal\"><h2>The window and the facade have to work together<\/h2><p>The facade doesn&#8217;t end at the wall: it also includes intersections, changes in materials, joints, and points where water must drain away. When one of those details is disrupted, rain can find a way in. <\/p>\n<p>Old material may peel away from the substrate, a joint may lose its adhesion, or a trim may allow water to seep into the cavity. Simply applying a layer over dust, loose material, or degraded sealant is no substitute for proper surface preparation. <\/p>\n<p>That\u2019s why we inspect the entire unit before considering <a href=\"https:\/\/verticalsbarcelona.es\/en\/vertical-works\/sealing\/\">sealing joints and cracks<\/a>. If the problem lies with the window sash, the seal, or the frame, you may need a window specialist; if it originates from the roof, the issue lies elsewhere. The decision must be based on the source of the problem, not on the service that\u2019s easiest to sell.  <\/p>\n<div class=\"vo-media-pair\"><figure><img data-opt-id=1687274616  fetchpriority=\"high\" loading=\"lazy\" src=\"https:\/\/mlpntm3khttd.i.optimole.com\/cb:b4cU.103b\/w:auto\/h:auto\/q:mauto\/f:best\/https:\/\/verticalsbarcelona.es\/wp-content\/uploads\/2025\/01\/1-FOTO-PRINCIPAL-sellado.jpg\" width=\"1536\" height=\"2048\" alt=\"Detail of a sealed exterior joint between brick courses\" loading=\"lazy\" decoding=\"async\"\/><figcaption>The interaction between materials is part of the review.<\/figcaption><\/figure><figure><img data-opt-id=1161856787  data-opt-src=\"https:\/\/mlpntm3khttd.i.optimole.com\/cb:b4cU.103b\/w:auto\/h:auto\/q:mauto\/f:best\/https:\/\/verticalsbarcelona.es\/wp-content\/uploads\/Reparacion-de-Fachadas-02-6.jpg\"  loading=\"lazy\" src=\"data:image/svg+xml,%3Csvg%20viewBox%3D%220%200%20100%%20100%%22%20width%3D%22100%%22%20height%3D%22100%%22%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%3E%3Crect%20width%3D%22100%%22%20height%3D%22100%%22%20fill%3D%22transparent%22%2F%3E%3C%2Fsvg%3E\" width=\"1080\" height=\"1440\" alt=\"Windows and ductwork on a courtyard facade\" loading=\"lazy\" decoding=\"async\"\/><figcaption>In a courtyard, the finials and the points above them are also important.<\/figcaption><\/figure><\/div><\/section><section id=\"vb-oct17-seguridad\" class=\"vo-reveal\"><h2>What can you do today without putting yourself at risk?<\/h2><p>Start by keeping people safe and documenting what you see.
