Best Mould Removal in Ottawa

Top 6 Mould Removal Services in Ottawa

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.

Below is a pricing table to give you an idea of how much you should set aside for professional mould removal services. The estimated costs indicated are current averages per square foot or cubic square foot.

Complete mould removal (1500 square feet with a widespread infestation on walls, ceilings, floors, etc.)$20,000 – $30,000
Mould removal per square foot$15 – $30
Hourly professional flat rate$75 – $100
Antimicrobial and antibacterial spraying per cubic square foot$1 – $10
Mould containment per cubic foot$0.30 – $0.75
Mould sealing and encapsulation per cubic square foot$5 – $75
HEPA vacuum removal plus dry ice blasting per square foot$0.75 – $1

These prices can change with several factors like how much initial testing costs and the techniques to be used in removal or cleaning. You’ll also have to consider if the mould has damaged certain parts of your house to the point where they have to be replaced or removed.
