El factor clave es si la grieta es estructural o estética. Las grietas finas (menores de 3mm) que no crecen suelen ser asentamiento — séllalas. Grietas más anchas, grietas horizontales o grietas que se ensanchan con el tiempo indican problemas de cimientos que necesitan evaluación profesional.
Para grietas estructurales, un especialista en cimientos evaluará si necesitas correas de fibra de carbono, anclajes de pared o recalce. Costo: CAD $3,000-15,000 dependiendo de la gravedad.
Consejo profesional: Toma fotos cada mes en el mismo lugar con una moneda como referencia de escala. Si la grieta está creciendo, tendrás evidencia con fecha para el ingeniero de cimientos y tu reclamación de seguro.
