Some types of mould can be removed with powerful household cleaning agents. But for those that pose greater health risks (like black mould), it’s best to get the services of the top mould removal company in Ottawa.

These are the experts who specialize in safe mould removal and can ensure that they’re gone forever. They use equipment and procedures that can’t be haphazardly substituted for unskilled handymen and generic tools.

It’s wise not to try to remove toxic mould by yourself or by someone not properly trained for it. But is professional mould removal something you can afford?

How Much Do Mould Removal Services in Ottawa Cost?

It will depend on how badly the mould has spread and how extensive the process will be. If it’s confined in a relatively small space like a bathroom, toolshed, or walk-in closet, you can expect to pay anywhere between $500 to $1,500.

Where the mould is located also plays a big part in the final costing. If it‘s spread everywhere to your walls, floors, ceiling, and attic space, you might have to pay tens of thousands of dollars.

Some mould removal experts charge per square foot or hourly, though. Other companies also provide flexible payment plans to accommodate clients’ budgets.
