The explosion on Activa Avenue in Kitchener was four months ago and it remains unsolved.

Those who live nearby say they want to know what happened.

But with no answer in sight, some are hoping city funded gas line inspections will ease their minds.

This was the first weekend when the gas lines leading to and from the homes were inspected.

Workers with Kitchener Utilities along with a private contractor are using a methane infrared air detector to find gas leaks inside homes and around the exterior gas line.

The homes being tested are in the vicinity of the Activa Avenue home that exploded in January.

Scott Peaker lives less than 100 meters away from where it happened.

“Not knowing what is going on is still keeping some people not sleeping.”  Peaker says.

Peaker invited CTV News inside his home to see the testing being done on his furnace.  He signed up for the free inspection to put his mind at ease.

“I am pretty sure everything is okay but what is kind of more important is knowing what kinda happened.” Peaker adds.

The City of Kitchener approved the inspection of 800 home and it will cost is $35,000.

Kitchener Councillor Kelly Galloway-Sealock says it’s a significant amount for the city but the money is coming out of the utility budget.   “If not all 800 homes participate that number will be a lot less.”

Home owners who decide to get the testing done they are reassure that something is being done especially have no cause behind the January explosion.  But not everyone felt the gas line testing was necessary.

But for Kitchener Councillor John Gazzola, he believes they should have waited until the Fire Marshal’s Office came back with a cause.  

“It’s totally premature and a waste of $35,000.” He says.

Gazzola lives within a half a mile of the area and notes the connections at his house are not being checked and he says they don’t need to be.

 But for many the inspection gives them some assurance that their homes are safe.
