For years, the owners faced water seepage near the entrance, threatening the plasterwork inside their historic home. This persistent issue also damaged the framework and wooden solar energy system. Despite consulting multiple companies, the solutions provided addressed only the symptoms, not the root cause. Wieldy Construction identified the source: the connection between the plasterwork, side window, and roof. They applied a sealant on December, just before the rains. The plastering team then covered the joint in dry weather. Completion depends on rain-free days during the rainy season.
