His work often features river views and coastal scenes where the weather is a primary subject. He used a muted palette to describe the grey skies and choppy waters of the North Sea. In drawings like Staande man met bontmuts en stok, he demonstrated a skill for figure studies that complemented his larger maritime compositions. His ability to capture the specific rigging of a schuit or the silhouette of a city wall shows a focus on accuracy. He avoided the dramatised storms of earlier painters; he preferred the quiet atmosphere of a working harbour.

Modern collectors value Rietschoof for his balance of technical precision and calm composition. His prints offer a window into the maritime history of the Dutch Republic without the clutter of symbols. The clean lines of his ships and the open space of his skies suit contemporary interiors. These works provide a sense of order and historical depth. They are effective in rooms that require a sophisticated, understated aesthetic.
