A simple Police patrol has ended with a fire rescue in Gagebrook.
Bridgewater Police were driving by a home on Tottenham Road at around 10.20pm on Monday night, finding the front bedroom alight.
Officers jumped into action, waking a resident and helping her from the house.
The woman and her dogs escaped the blaze, police then helping a neighbour use a garden hose to suppress the dire until Tasmania Fire Service arrived.
Smoke damage to the house and water damage to the front bedroom is expected to cost around $40,000.
The address had working smoke alarms fitted at the time.
Investigations into the cause of the blaze continue throughout today.
Meantime a Colebrook woman may never know why her home and car burned to the ground early yesterday.
The 1900's double storey home and a Citreon vehicle parked next to it were completely destroyed.
TFS investigators believe clothes which were drying near a woodheater could be a factor.
