A fire at a home on Ralston Place in Waterloo forced the evacuation of several residences on Wednesday but was quickly knocked down.

Firefighters responded around 2 p.m. and were able quickly contain the blaze, but heavy smoke forced the evacuation of a number of homes in the area and the closure of the road.

A homeowner noticed the blaze and called 911 before safely leaving the home. There are reports that three people were in the home at the time.

The fire originated in the garage, where building supplies for an addition to the home were being stored. The supplies were destroyed.

Workers were apparently in the home's backyard framing an addition for the home at the time but no one was injured.

While the fire doesn't appear to have spread beyond the garage, there is smoke and water damage to the home.

There is no word yet on the cause of the fire, but the family will not be able to return for the night.

John Percy of Waterloo Fire Rescue says "We're just checking for spread of the fire into the actual house portion, and once that's done, once it's safe to do so, we'll start a fire investigation to determine how exactly where and how it started."

At the peak of the blaze, three fire trucks and 13 firefighters were on scene. Crews were still checking for hotspots around 4 p.m.

A preliminary estimate puts the damage at $100,000, but that could increase as the fire investigation continues.
