Versteegh is known for his nocturnal interior scenes. He used artificial light sources like oil lamps and candles to define his compositions. In works such as De avondschool, the light source is often hidden or placed low. This technique creates sharp contrasts and soft shadows. His brushwork is precise and smooth, following the tradition of the Dutch fijnschilders. He focused on domesticity and quiet study, capturing moments of concentration in private spaces.

Modern collectors value Versteegh for the atmospheric quality of his candlelit rooms. His prints bring a sense of stillness to a living space. The dark backgrounds and focused lighting make these works suitable for rooms with subdued lighting. His scenes of kitchens and schools offer a glimpse into historical daily life. These images provide a calm, scholarly aesthetic that fits well in a home library or study.
