The Samaritan's Purse is looking for volunteers to help rebuild dozens of flood-damaged homes in both Calgary and High River.

Nearly seven months after the flood, many homeowners are still struggling to get the help they need to repair and rebuild. The Christian aid group is trying to help families who aren't getting full government and insurance payouts — a problem it says is fairly common.

"There are a lot of gaps out there," said Dan Rossi with Samaritan's Purse. "We're working with about 50 people in Calgary and High River and those are similar stories that we hear about as well."

More than 25,000 claims were filed in the aftermath of the June flood, according to Property Claim Services Canada, which tracks losses arising from catastrophic events in the country. 

Four people died and more than 100,000 were forced from their homes in Calgary and other communities.

For flood victims like Blaine Astra, who lost his High River home to the floodwaters, waiting for help from insurance companies and the province has been a nightmare.

You have nothing," said Astra, who has three children and is currently living in his in-laws' Calgary basement. 

Astra says his insurance won't cover the damage and the government will only pay about 30 per cent of his rebuilding costs. 

"It's horrible, it's actually just horrible. It's an emotional crush. It just kills you — I am killed."
