I. Introduction
When mould appears in your home or building, one of the first questions most people ask is, “How much will it cost to get rid of this?” The short answer is: it depends. Mould remediation costs can vary widely depending on the extent of the contamination, where the mould is located, how accessible the area is, and what materials have been affected. No two mould jobs are the same, and that’s why a professional on-site assessment is necessary to provide an accurate quote.
It’s important to understand that mould isn’t just a cosmetic problem, it can pose serious health risks, especially to children, seniors, or anyone with allergies, asthma, or respiratory conditions. Over time, it can also damage the structure of your property by weakening drywall, rotting wood framing, and spreading into hidden areas. Proper removal is essential not only for your health but also for the long-term integrity of your home or building.
This article is meant to provide a general overview of mould remediation costs in Winnipeg. While it can help you get a rough sense of what to expect, please don’t use this guide to judge what your specific remediation will cost, every project is different. The only way to know for sure is to have a certified professional perform a detailed inspection and provide a site-specific quote.

II. Typical Mould Remediation Cost Ranges in Winnipeg
While every job is different, here’s a general breakdown of what you might expect based on typical mould remediation projects in Winnipeg and Manitoba:
• Very Small-Scale Remediation: ($350 – $1,500) This might include light mould under a kitchen sink, in a small closet, or around a single window frame. These jobs are contained, require minimal or no demolition, and are often completed in one day or less.
Includes: basic containment, negative air, selective minimal demolition or treatment only, mould removal, surface treatment, final cleaning and very basic reporting.
• Small-Scale Remediation: ($700 – $3,000) This might include mould in a small closet, along baseboards/trim, a small section of drywall/material removal, or moderate spotting on walls. These jobs are contained, require minimal demolition, and are often completed in one day.
Includes: basic containment, HEPA air scrubber, selective demolition, mould removal, surface treatment, final cleaning and basic reporting.
• Moderate-Size Remediation: ($2,500 – $7,000) This often involves a bedroom, bathroom, or utility space where walls, ceilings, and building materials like insulation are affected. These jobs are typically multiple days (1-4).
Includes: inspection, containment zone, use of negative air pressure, removal of some drywall/insulation, disinfecting, drying, and post-cleaning, in-depth reporting.
• Attic or Large-Area Remediation: ($7,000 – $12,000+) Widespread attic mould caused by ventilation issues, condensation, or roof leaks can drive up costs due to insulation removal and complex cleaning requirements. These jobs are typically multiple days (3-6).
Includes: moderate containment zones, insulation removal, framing treatment (such as wire brushing or soda blasting), air filtration, and post-cleaning, testing and reporting.
• Severe or Multi-Room/Commercial Remediation: ($10,000 – $20,000+) Major projects in multiple rooms or commercial properties require larger crews, extended containment, and often third-party testing or air clearance. These jobs are typically multiple days to weeks.
Includes: extensive labour, detailed documentation, third-party air quality clearance (if required), and extended drying or equipment usage.
Important Note: These are only general ranges. The exact cost of mould remediation depends on several factors: the size of the affected area, material type, level of contamination, containment requirements, travel & accessibility, and whether post-clearance testing or rebuild services are needed. No two projects are the same.
III. What Affects the Cost of Mould Remediation?
Mould remediation involves much more than just tearing out damaged materials. At Relief Restorations, we follow ethical and legal industry standards that require us to set up proper containment, run HEPA-filtered air scrubbers, a trained and certified crew with PPE, safely handle contaminated materials, document our work from start to finish, and more. These steps are essential to prevent cross-contamination, protect your health, and ensure the mould does not return.
Here are the key factors that affect the cost of mould remediation:
1. Extent of Mould Contamination: The more mould there is, the more time, equipment, and labour are needed to remove it. Costs can range significantly depending on whether we’re dealing with a small visible patch or a widespread issue that’s travelled into hidden cavities or become airborne. More contamination typically means more demolition, deeper cleaning, and longer containment time.
2. Location of the Mould: Where the mould is located plays a big role in how complex the job will be.
Attics often require insulation removal and involve tight working conditions.
Basements may have poor ventilation and moisture issues.
Crawl spaces are difficult to access and can pose additional safety risks.
Wall cavities and HVAC systems require specialized removal and cleaning techniques. Each location presents its own set of challenges that affect both time and cost.
3. Type of Materials Affected: Different materials respond differently to mould and remediation.
Drywall is often removed and disposed of entirely.
Insulation traps spores and typically must be replaced.
Framing and subflooring may need sanding, wire brushing, or antimicrobial treatment.
Flooring materials (like carpet or laminate) require specific removal procedures. Each material has its own handling requirements, and safe disposal must follow local regulations.
4. Access and Containment Requirements: If the area is difficult to access or isolate, the cost of setting up proper containment goes up. We use poly sheeting, zipper walls, and negative air machines to create sealed environments that prevent the spread of spores. Tight areas, multi-level homes, or finished spaces may need more extensive setup, especially when protecting the rest of the property from contamination.
5. Testing and Reporting: In some cases, mould remediation projects include pre- and/or post-remediation air quality testing, either for homeowner peace of mind or as part of regulatory compliance. We work with third-party laboratories to provide independent verification when needed. These services add to the cost but offer confidence that the job was done right.
6. Reconstruction Needs (If Any): Remediation focuses on removal and cleaning, not rebuilding. If drywall, vapour barrier, baseboards, or insulation are removed during the process, reconstruction is a separate scope of work. While some clients choose to handle this portion themselves or hire a contractor, Relie Restorations is specialized in the remediation side of things, we can provide referrals to trusted trades or general contract and coordinate rebuilds through our partner network.
Mould remediation is a highly technical process designed to protect your health and your home, not just “rip out and replace.” That’s why pricing can vary so widely, and why every job requires a custom assessment.
IV. What’s Included in Professional Remediation (and Why It Matters)
When it comes to mould, cutting corners can have serious consequences. At Relief Restorations, we follow a detailed, methodical process that aligns with industry best practices, legal requirements, and our own commitment to safety, quality, and transparency. This process doesn’t just eliminate mould, it prevents it from coming back, protects your health, and ensures the job is done right the first time.
Here’s what our professional mould remediation service includes, and why each step matters:
1. Inspection & Moisture Survey: Before any work begins, we perform a thorough inspection of the affected areas using moisture meters, hygrometers, and thermal imaging cameras. This allows us to identify both visible and hidden sources of moisture and mould.
Why it matters: You can’t fix what you can’t see. Finding the root cause is essential for preventing future growth.
2. Containment Setup: We install poly sheeting to isolate the work area, then use HEPA-filtered negative air machines to maintain negative pressure and filter the workspace. This prevents cross-contamination by ensuring airborne spores don’t escape into clean areas.
Why it matters: Proper containment is required and crucial for keeping your family or tenants safe during and after remediation.
3. Safe Removal of Contaminated Materials: We remove mould-affected materials like drywall, insulation, or flooring with care. Our technicians wear full PPE (including respirators, suits, gloves, eye protection, and more), and all contaminated debris is sealed, labelled, and disposed of according to safety regulations.
Why it matters: Mould is a biohazard. Safe handling protects everyone on-site and complies with provincial and federal guidelines.
4. Surface Treatment: Once the contaminated materials are removed, we treat all remaining surfaces with antimicrobial disinfectants. This may include scrubbing, sanding, wire brushing, or application of a mould-inhibiting sealer if needed.
Why it matters: Killing spores on exposed framing and surrounding materials is vital to ensure a clean, healthy environment.
5. Drying & Dehumidification: (not always required) Using professional-grade dehumidifiers and air movers, we dry the space thoroughly to remove any lingering moisture.
Why it matters: Moisture is the key ingredient for mould growth. Proper drying prevents it from coming back.
6. Post-Remediation Cleaning: After remediation, we perform a full HEPA vacuuming and damp wipe-down of all surfaces within the containment zone.
Why it matters: Even dead mould spores can trigger allergic reactions, this final cleaning step ensures the space is safe.
7. Optional or Required Post-Testing: We offer third-party air quality testing (before and/or after remediation) if required by a homeowner, insurance provider, or for peace of mind. These tests are often performed by an independent lab.
Why it matters: Post-remediation verification confirms the work was successful and the air is clean.
Additional Services and Documentation
Fogging: We apply a fine mist of antimicrobial solution throughout the affected space to treat airborne spores or hard-to-reach surfaces.
Sealing: We apply a mould sealer to bind particulates, reduce odor, and reduce food sources for mould growth. Our mould sealers contain mould inhibiting properties to reduce the risk of recontamination.
Reporting: We provide detailed documentation of our process, including photos, equipment logs, and service reports.
Client Support: We explain every step and answer all your questions to ensure you're informed and confident in the work being done.
Mould remediation is about more than just clean-up, it’s about protecting health, property, and peace of mind. At Relief Restorations, we don’t cut corners, and our process reflects that.

V. DIY vs Professional Mould Removal
It’s natural to consider a do-it-yourself approach when you spot mould, especially if it appears small or surface-level. However, there’s a big difference between cleaning a bit of mildew on a bathroom tile and remediating an active mould issue that has penetrated walls, insulation, or framing.
Professional remediation isn’t just about removing visible mould; it’s about eliminating the source, containing the spread, protecting health, and ensuring it won’t return. Below is a comparison of key factors to help you understand the difference between DIY efforts and hiring a certified team like Relief Restorations.
DIY can sometimes handle very minor surface mould, but it’s rarely effective for anything beyond cosmetic cleaning. Worse, incomplete or incorrect DIY efforts can disturb spores, spread the problem, and drive up eventual remediation costs.
Hiring a professional ensures the mould is properly identified, safely removed, and won’t come back due to hidden moisture or missed contamination. It also means peace of mind, for your health, your family or coworkers health, your home, and your investment.
VI. Why You Need a Custom Quote
When it comes to mould remediation, there’s no such thing as a “standard” job. Every home, every building, and every infestation is unique. That’s why pricing varies, and why online estimates or generic quotes often fail to reflect the true scope of work needed.
Several factors can influence the cost of a mould remediation project:
Square Footage Affected – A small patch in a closet is vastly different from an attic or basement-wide issue.
Level of Damage – Some mould is surface-level; other times it’s penetrated walls, insulation, framing, or floors.
Service Requirements – Will there be post-testing? Fogging? Drying? Sealing? Emergency response? Reconstruction needs?
Documentation & Reporting – Some projects require detailed reports, photos, and clearance letters, especially for property managers, insurers, or real estate transactions.
Accessibility & Home Layout – Tight spaces, finished basements, or multi-storey homes can affect setup and labour time.
Travel Time – Remote locations or sites outside city limits may incur additional travel-related costs.
Because of these variables, we don’t offer cookie-cutter pricing. Instead, we follow a clear and straightforward process:
Site Visit – We arrive at your property to inspect the affected areas, assess visible and hidden damage, and identify moisture sources.
Moisture & Damage Assessment – Using tools like moisture meters and thermal imaging, we map out the full scope of contamination.
Transparent Quote – Based on what we find, we provide a detailed quote that outlines what needs to be done, why, and what it will cost.
There’s no pressure, no obligation, just clarity. Our goal is to give you the information you need to make an informed decision that protects your health, your property, and your budget.
VII. Final Thoughts
Waiting to address mould issues can lead to serious health risks, worsening structural damage, and escalating repair costs. The longer mould is left untreated, the harder and more expensive it becomes to fully remediate. Acting quickly not only protects your home or business but also safeguards your family, employees, or tenants from harmful exposure.
