Glad's firm went bankrupt in connection with the Great Crash of 1929. They had to sell both their properties and moved into an apartment in Bredgade. Grethe Glad started the Margrethe School in 1931. After Carl Glad had successfully revived his business a few years later, they were in 1937 able to purchase a property at Frederiksholms Kanal and to reacquire Rågegården. Glad was also involved in the Toro Oil Corporation Denmark Limited A/S at Bredgade 76. Glad kept the Isotta Fraschini until the early 1970s when it was then sold to his Rågeleje neighbors Rita and Erik Orth.
