How Long Does Professional Mould Remediation Take?

How Long Does Professional Mould Remediation Take?

Discovering mould in your home or business can be stressful—but understanding the remediation process can help ease those concerns. At Advanced Remediation Solutions Inc., we know that one of the first questions clients ask is: How long does mould remediation take?





The answer depends on several factors, including the size of the affected area, the type of building materials involved, the severity of the contamination, and whether other hazards like asbestos or compromised insulation are also present. In this article, we’ll break down typical timelines for mould removal in Edmonton, and explain what to expect at every stage of the process.


Step 1: Initial Inspection and Testing (1–3 Days)

Every successful remediation project begins with a detailed assessment. Our team will conduct an on-site inspection to determine the location, size, and severity of the mould infestation. During this visit, we also check for underlying moisture problems that may have caused or worsened the contamination.

If needed, we proceed with mould testing in Edmonton (mold testing in Edmonton), collecting samples from air and surfaces. These are sent to a certified lab, with results typically available within 24 to 72 hours. This testing helps confirm mould species and informs the level of containment and personal protective equipment (PPE) required.


Step 2: Planning and Site Preparation (1–2 Days)

Once test results are received, our team develops a customized remediation strategy. This plan includes:

  • A detailed scope of work

  • Pricing and timelines

  • Containment and ventilation protocols

  • Safety procedures and PPE requirements

  • Adherence to IICRC S520 and OH&S guidelines

If additional hazards are present—such as asbestos—asbestos removal in Edmonton must be scheduled before any physical mould remediation begins. For buildings constructed before the 1990s, this is a critical safety step.

When insulation is affected or suspected of containing contaminants, insulation removal in Edmonton is also added to the project scope, which may extend the total duration by 1 to 2 days depending on area size and complexity.


Step 3: Mould Remediation (1–5 Days)

The actual remediation work can take anywhere from a single day to a full work week. Small, localized infestations (under 10 square feet) can often be handled quickly. Larger projects—especially those involving multiple rooms, HVAC contamination, or structural materials like drywall and wood—require more time.

Our certified professionals use specialized containment methods to isolate the work area, preventing cross-contamination. Negative air machines with HEPA filters maintain clean airflow, and all affected materials are either cleaned or removed entirely, depending on the severity of the growth.

Where insulation is contaminated, insulation removal in Edmonton is completed safely, followed by thorough surface cleaning and drying.

If asbestos-containing materials are involved, we’ll coordinate asbestos abatement in Edmonton before any demolition or disturbance takes place. This process can add 1–3 additional days, but is essential for protecting occupant health and meeting provincial regulations.


Step 4: Post-Remediation Testing and Restoration (1–2 Days)

After all visible mould has been removed and surfaces are cleaned and sanitized, we conduct post-remediation verification. This includes visual inspection, moisture testing, and sometimes repeat mould testing in Edmonton (mold testing in Edmonton) to confirm the space is safe and free of elevated spore counts.

Only once the area passes all clearance checks do we proceed with final repairs or re-insulation. If asbestos was present, post-project clearance air testing is also required to complete the asbestos abatement in Edmonton process.
