He was registered in Gorinchem during the years 1652-1683, according to the RKD. In 1658 he is registered as making sketches of heraldic shields for the city of Gorinchem, and in 1659 he is mentioned in a notarized document as being a painter and an architect. In 1679 he fled to The Hague for a short period due to accusations of corruption, and in 1683 he left Gorinchem definitely for Noordwijk, where he later died. Gorinchem and the surrounding towns all had examples of his stained glass work.
Houbraken goes on to write that despite this talent and becoming mayor of Gorinchem himself, Ulft would go down in history for his own contributions to art in the area of oil painting and engraving old ruins, showing each crack and cranny.
He painted many Italianate landscapes with monuments and triumphal arches, but these were based on Italianate prints, because according to Houbraken he had never been to Italy. Ulft"s painting of the old city hall of Amsterdam shows the whalebone hanging from the vierschaar (courtroom) given to the city by Willem Barentsz.
A similar whalebone still hangs in the Haarlem City Hall. This painting, highly detailed and populated with townspeople in all manner of dress and occupation, was enough to keep his name famous for centuries, according to Houbraken.
