During his time with the D'Oyly Carte Opera Company, Grossmith's father and mother died (in 1880 and 1882, respectively). Throughout this period, Grossmith continued to perform his sketches, often late at night after performing at the Savoy, and continued to write new sketches, such as "Amateur Theatricals" (1878), "A Juvenile Party" (1879), "A Musical Nightmare" (1880), and "A Little Yachting" (1886). He also wrote the music for Arthur Law's short comic opera, "Uncle Samuel" (1881), the one-act curtain raiser that preceded "Patience" on the Opera Comique programme. His "Cups and Saucers" was revived and played with "Pinafore" and also played by the company on tour. Other comic operas by Grossmith during these years included "Mr Guffin's Elopement" (1882) and "A Peculiar Case" (1884, both with libretti by Arthur Law) and "The Real Case of Hide and Seekyll" (1886). Grossmith also continued to give his "society" and other entertainments, often late at night after his performance at the Savoy. He also composed the music for another comic opera, "The Great Tay-Kin" and another piece, both with libretti by Arthur Law, which were performed at Toole's Theatre in 1885.
