And this week they were out in force with other cast members at the unveiling of a plaque in her memory in London's Mayfair.
Todd Carty - her character Pauline Fowler's son Mark in the soap - said: "She meant the world to me."
He joined James Alexandrou, who portrayed younger son Martin, and Natalie Cassidy – aka her daugter-in-law Sonia – in honouring Wendy, who died from cancer in February, aged 65.
When Wendy passed away she left Natalie her lucky necklace - which she wore to the ceremony.
"Ever since I've had it I’ve had nothing but happiness, luck, jobs and money coming in,' said the brunette actress. "I swear to God she’s looking after me."
Unveiling the plaque at the Shepherd's Tavern pub – which Wendy's parents used to run and where she lived when she was a child – was Are You Being Served creator David Croft.
Other former Albert Square residents also there included Letitia Dean, Leslie Grantham and John Altman. They joined Wendy's widower John Burns.
