Widowed mum-of-two Yvonne McCorquodale, 66, was pulled from her house in Newbarns Road, Barrow on Wednesday July 15 and taken to a hospital in Liverpool, where she died on Tuesday evening.
The former Girl Guides volunteer lived alone after the death of her husband, Malcolm.
Family friend Denis Horan, 39, who has known the McCorquodales since his parents moved to nearby Abbots Vale in the late 70s, said she had been a great help after his mum had been diagnosed with cancer.
He said: “She was a lovely lady, always full of wisdom and advice.
“My mum became ill at the start of last year and Yvonne was the one who was always there popping in and out for a chat and just someone to be with.
“She was a great strength to my mum in her final weeks.
“It’s a real shame, it’s a shock for our family and to the whole community. Of the old school of Newbarns, there’s not many left now round that area that we know from growing up on the 80s and 90s.
“She was one of the old faces and we thought she’d always be there.
“It’s a real loss and in such tragic circumstances. Our thoughts and love go out to her daughters Corin and Deanne at this very sad time and anything we can do for them we certainly will.”
Natalie Davey, 27, who runs the Insight Card Reading stall at Barrow Market Hall, said Mrs McCorquodale was “like a mum to her”.
She said: “The day I opened my stall she was the first person I gave a reading to. The next day she helped by watching the stall for me and that was it.
“When I wasn’t well she ran the stall and did everything. She was one of the closest things I had to a mother.
“She was the one person who had faith in me and she never let me down. She always saw the good and the potential in people and never had a bad word to say about anyone.”
Police have confirmed the fire is not being treated as suspicious.
Cumbria Fire and Rescue Service are still working to determine the cause of the blaze.
A spokesman said: “We are still investigating the cause of the fire but at this stage it appears to have started accidentally.”
