Mould Removal in Niagara Falls
Niagara Falls has more moisture to manage than most cities: humid summers along the Niagara River, the Welland River and Chippawa Creek running through the south end, clay soils that hold water against foundations, and basements across the city that took on water in the July and August 2026 storms. When that moisture sits in drywall, insulation or framing, mould (mold) follows, often out of sight.
DKI – Miller Restoration finds the moisture, removes the mould safely under containment, fixes the cause, and documents the work for your insurer, in homes, rentals, hotels and businesses across Niagara Falls.
Mould Removal and Inspection Across Niagara Falls
Mould is a moisture problem first. Remove the mould without finding and fixing the water, and it comes back. Every inspection starts with moisture meters and thermal imaging to map where water is hiding behind walls, under floors and in attics. Then we remove contaminated materials, clean the structure, and dry it to verified targets.
Every job is handled by IICRC-certified technicians, and older homes are checked for asbestos before demolition, part of our mould remediation and asbestos testing service across Niagara. For active leaks or flooding, see our flood cleanup in Niagara Falls.
In Niagara Falls homes and businesses, the mould we remove most often starts with:
Basements that flooded or had a sewer backup in 2026
Slow leaks behind walls, under sinks and around windows
Attic condensation from poor ventilation and bath fans
Humid, closed-up basements and crawl spaces
Plumbing leaks in hotels, rentals and commercial units
What Our Niagara Falls Mould Crews Deliver
Mould Inspection & Moisture Mapping
We find the full extent of the problem with moisture meters and thermal imaging, not just what is visible, and explain what we found before any work starts.
Containment & HEPA Air Scrubbing
Work areas are sealed with poly sheeting and kept under negative air with HEPA filtration, so spores do not spread to the rest of the building.
Safe Removal & Cleaning
Mouldy drywall, insulation and other porous materials are removed and bagged, and framing and hard surfaces are HEPA-vacuumed, cleaned and treated.
Drying, Prevention & Rebuild
The structure is dried to documented targets, the moisture source is corrected or flagged for repair, and our crews rebuild what was removed.

Is Mould Covered by Insurance?
Many Ontario home policies limit or exclude mould unless it results directly from an insured event, such as a burst pipe or a covered sewer backup. If mould follows a water loss, report it to your insurer with photos and the date you found it.
We document every job with moisture readings, photos and a line-item scope, so your adjuster can see where the mould came from and what it took to remove it.
Mould in Niagara Falls – What Homeowners Ask
How do I know if I have mould behind my walls?
A musty smell that gets stronger when the heat comes on, staining or bubbling paint low on the wall, warped baseboards and worsening allergy symptoms are the common signs. A moisture and thermal-imaging inspection confirms it without opening walls unnecessarily.
Can I remove mould myself?
Health Canada’s general advice is that small patches, under about one square metre on a hard surface, can usually be cleaned with water and dish soap while wearing gloves, eye protection and an N95 mask. Larger areas, mould that keeps coming back, or mould on materials soaked by floodwater should be removed by professionals.
Is it mould or mold?
Both. “Mould” is the Canadian spelling and “mold” the American one. Whatever you call it, the risk is the same: it can trigger allergies, asthma and respiratory irritation, especially for children, seniors and anyone with a weakened immune system.
Do you test for asbestos before removing mouldy drywall?
Yes, in homes built before the 1990s. Drywall joint compound, plaster and some insulation from that era can contain asbestos, so we sample suspect materials before demolition and plan the work around the results.
How long does mould removal take?
Small jobs can often be finished in a day or two; larger jobs that need drying and rebuilding take longer. We give you a written scope and timeline before work starts.
How fast can you get to Niagara Falls?
Crews are dispatched from our St. Catharines base, about 20 to 30 minutes away in normal traffic. Mould linked to an active leak or sewage is treated as an emergency; other inspections are booked at a time that suits you.
