His approach to portraiture was equally controlled. In works like Portret van Johannes Huibert Prins and Portret van Nicolaas Muys, Verburgh used a sober palette and clear lighting. He avoided the theatrical flourishes common in 19th-century European art. Instead, he focused on the quiet domesticity of his subjects. Zittende vrouw met een slapend meisje aan haar knieën shows his ability to capture stillness. The figures are composed with a geometric stability that recalls Dutch interiors of the previous century. His draughtsmanship is firm, prioritising line and form over loose brushwork.

Modern collectors value Verburgh for his restraint. His drawings and paintings provide a sense of order and historical continuity. The muted colours and architectural subjects suit contemporary interiors that favour clean lines. By choosing a print of a Verburgh ruin or portrait, a buyer brings a piece of Dutch academic tradition into a room. These works offer a window into a period of history where the past was being preserved through careful observation.
