His technique relied on a palette of muted earth tones. He avoided the bright tones common in French Impressionism. Instead, he used a direct, observational style to record light reflecting off damp brickwork and canal water. His work is distinct for its structural clarity. He prioritised the weight of buildings over the movement of crowds. This approach gives his street scenes a quiet, permanent quality.

Collectors today value Van Teijn for his unsentimental view of history. His paintings provide a window into a specific era of Dutch urban life without relying on nostalgic tropes. The neutral colour schemes make his prints suitable for various interior styles. They offer a sense of calm. His focus on historical architecture appeals to those who appreciate the intersection of art and topography.
