Inspection apps for Canada: mold, homes and cold-climate moisture
For Canadian inspections, pick DampApp Pro when the question is mold and moisture, PropertySurvey Pro for pre-purchase home inspections and rental or condo reports, and HousingSurvey Pro if you run community or social housing. The first two are free to download and use.
Canada has no national home inspection or rental standard. The National Building Code is a model that each province and territory adopts or adapts, tenancy and maintenance rules are provincial or municipal, and home inspector licensing depends on the province: British Columbia and Alberta license home inspectors, and Quebec's Régie du bâtiment certifies pre-purchase inspectors, with the certificate mandatory from 1 October 2027.
The climate sets most findings. Long heating seasons push warm, moist indoor air into cold walls and attics, ice dams form at the eaves, spring thaw tests basements and foundations, and condos add the question of who repairs what. Health Canada notes that mold can begin to grow within 48 hours where there is excessive moisture.
Snow-bound rural properties and unheated basements are no obstacle to offline capture. On the free tier of DampApp Pro or PropertySurvey Pro you still run full inspections and export PDFs (with a watermark), with 3 free uses a month of each AI tool and storage for 25 surveys on the device; Pro is optional and priced in Canadian dollars in the App Store and Google Play.
Mold inspectors, home inspectors and remediation firms
Mold inspection app for Canada
For mold work in Canada, use DampApp Pro: it takes temperature and relative humidity in °C or °F, works out the dew point on the device, pins each moisture reading to its wall and photo, and finishes the PDF on site, even in a basement with no signal.
Health Canada does not recommend testing the air for mold, so a strong report rests on the moisture source instead: where the wall is wet, how its surface temperature compares with the dew point, and whether the extract fans run. Health Canada also recommends that a qualified professional assesses and cleans up any single patch larger than 3 m².
Cold-climate moisture is often hidden. Condensation inside walls and frost in attics show up as staining long after the cause, so the U-value and condensation checks help explain the mechanism, and a follow-up visit in another season can confirm it.
What DampApp Pro records
- Temperature and humidity in °C or °F, with dew point
- U-value and interstitial condensation checks
- A grid of moisture readings for every wall (Pro)
- Ventilation testing
- Seasonal follow-up visits that start from the last readings
Home inspectors and pre-purchase inspectors
Home inspection software in Canada
PropertySurvey Pro is a home inspection app for Canadian pre-purchase work: walk the house room by room, drop each photo onto a floor plan, note the weather and snow cover, and produce the PDF on site.
Who may inspect depends on the province. British Columbia requires home inspectors to hold a licence from Consumer Protection BC; Alberta licenses both home inspectors and home inspection businesses; and in Quebec the Régie du bâtiment du Québec has certified pre-purchase inspectors since 1 October 2024, with the certificate becoming mandatory on 1 October 2027. Elsewhere, check the current provincial position before you rely on it.
Winter limits the evidence. Snow on the roof, frozen ground and systems not running are inspection limits, and the report should say so and recommend a return visit where it matters.
What PropertySurvey Pro records
- Room-by-room ratings with numbered photo captions
- Defect pins on a floor plan of the house
- Weather on the day of inspection
- Access limits and exclusions in the report
- Cost notes in Canadian dollars
Landlords, property managers and condo managers
Rental and condo condition reports in Canada
For rentals and condos, PropertySurvey Pro records move-in and move-out condition and routine inspections with matching photos, so a later dispute is judged on dated evidence.
Residential tenancy law is provincial, and maintenance standards differ. Ontario's Maintenance Standards regulation under the Residential Tenancies Act, 2006, for example, requires interior walls and ceilings to be kept free from mold, mildew and other fungi, alongside municipal property standards by-laws. In a condo, note whether a defect is in the unit or the common elements, because responsibility depends on the province and the declaration.
What PropertySurvey Pro records
- Move-in and move-out photos taken from matching angles
- Room-by-room condition across units
- Spoken room walk-throughs turned into entries you check
- White-label PDF reports (Pro)
Community and social housing providers and contractors
Mold evidence for community and social housing in Canada
HousingSurvey Pro is for community and social housing providers and their contractors who manage mold and moisture across many homes. Field staff record evidence offline with a location stamp and a hash chain that shows any later edit, and the portal carries each case from report to work order to follow-up.
There is no single Canadian maintenance rule for social housing, so record the province or territory and the municipality whose rules apply to each home before choosing a checklist. Providers can start with the free Solo plan; signing in to the app requires an organisation subscription.
What HousingSurvey Pro records
- Location-stamped photos and moisture readings
- Hash-chained evidence records per property
- Work orders and seasonal re-checks tracked in the portal
- Links to housing systems by API, webhooks or EDI

What surveyors meet on site
Condensation inside walls and frost in attics
Warm, moist air leaking through gaps in the air barrier condenses on cold sheathing and roof decks through the winter. Photograph staining, record the humidity indoors and note where you could see the air and vapour barrier.
Ice dams at the eaves
Heat escaping into the attic melts snow that refreezes at the cold eaves and backs water under the shingles. Record the ceiling stains below, the attic insulation you could see and any snow cover that limited the roof inspection.
Basements after the spring thaw
Snowmelt and saturated ground test foundation walls, window wells and floor joints each spring. Note efflorescence, tide marks and the grading outside, and say when the inspection took place.
Radon, which no visual inspection can see
Health Canada's guideline for radon is 200 becquerels per cubic metre, and only a test can measure it. A visual inspection should say plainly that radon was not tested.

Survey app questions from Canada
Is there a free mold inspection app in Canada?
Yes. Download DampApp Pro and you can carry out real mold inspections at no charge on iPhone, iPad or Android. The free version works without signal, adds a watermark to PDF reports, gives 3 free uses a month of each AI tool and keeps up to 25 surveys on the device. Pro is an optional upgrade, shown in Canadian dollars in the stores.
Do home inspectors need a licence in Canada?
It depends on the province. British Columbia and Alberta require home inspectors to be licensed, and Quebec requires an RBQ certificate for pre-purchase inspectors from 1 October 2027. Rules elsewhere differ, so check with the province before you rely on them.
Does Health Canada recommend testing the air for mold?
No. Health Canada does not recommend testing the air for mold. Its guide focuses on finding the moisture, keeping indoor relative humidity between 30% and 50%, and having a qualified professional deal with any single patch larger than 3 m².
Can I use Celsius and Canadian dollars in my reports?
Yes. Enter temperature and relative humidity in °C (or °F) in DampApp Pro and it works out the dew point for you; PropertySurvey Pro prepares cost notes in Canadian dollars.
Does it work offline in rural areas and basements?
Yes. Everything from photos to dew point checks to the finished PDF runs on the device, so a basement or a cabin with no coverage is no problem. Pro subscribers can sync to the cloud later, once back in coverage.
Does the app certify compliance with the building code?
No. The apps record what you observed, measured and photographed. They do not certify compliance with the National Building Code, a provincial code or a municipal by-law, and the inspector makes every judgement.
Which app suits a social or community housing provider?
HousingSurvey Pro. Field staff use the offline app, and the office tracks work orders, follow-up visits and evidence for every home in a web portal. The Solo plan is free, and larger teams pay per surveyor per month.
