The Redland community is rallying around two families left homeless last week after fires ravaged their properties.
Although nobody was injured in either of the fires one at Russell Island and one at Redland Bay police and firies are warning households to take care with heaters over winter.
Redland Bay fire station officer Ken Sweet warned those going away for holidays to switch off and unplug all electrical appliances.
He said owners of rental properties were responsible for ensuring working fire alarms at the start of leases but it was up to tenants to maintain them.
He also said many non-brand name phone and ipad chargers had been blamed for sparking fires.
Fire broke out in the two-storey brick home of a family of 10, on holiday in New South Wales, just after 4am on Thursday.
The intensity of the fire cracked brick walls which also crumbled and then caved in before the roof collapsed.
Firefighters from Redland Bay, Capalaba and Beenleigh were on the scene within minutes but were unable to save the building, which will be pulled down.
Capalaba fire chief Paul Omanski said a passerby notified emergency services but the blaze was already well under way.
Firies were on site just after 4.30am and used foam and water to douse the flames licking the top storey.
Crews were still hosing down what was left of the house three hours later.
Redland Bay Police senior constable Kim Ensinger said an investigation would be held.
Neighbour Nic Smeelie said people with donations for the Redland Bay family can use the Go Fund Me donation website.
The family, whose children range in age from two to 13, is believed to have lost most possessions.
It was the second fire to destroy a family home this week after a Russell Island house was gutted by fire on Saturday.
Mum-of-two Debra Morgan, 34, jumped from a window of her Fiji Street home as her house was engulfed in flames.
She only had enough time to grab her handbag and one shoe. Her two children, son Zayne, 5, and daughter Zayah, 11, were visiting friends.
Mrs Morgan's sister, Louise Staunton, said the family's dog was able to get out but unfortunately the cat, Violet, perished in the fire.
"It burnt so quickly and all that's left is two partial walls and we could only salvage a small box of burnt photos, a washing basket of clothes and a small jewellery box," she said.
"The kids have lost everything. But a kind woman has promised to donate an ipad for Zayne who has some learning issues.
"It was so lucky that the children weren't at home at the time because the fire spread so quickly."
Fire fighters took more than an hour to bring the blaze under control and are still investigating the cause.
Two charred walls are left of the house are left standing. But Mrs Morgan plans to rebuild on the site.
A Facebook page, Russell Island Family Homeless After House Fire, has been set up to assist the family and Bendigo Bank has set up a bank account.
Russell Island State School community and P&C are rallying around the family to ensure the children have uniforms, lunchboxes and books.
The family, which has short-term accommodation on the island, needs boys' clothes, size eight, and girls' shoes and clothes for size 12.
Immediate needs are new shoes and socks, winter coats and jumpers, new bedding, personal toiletries and underwear.
