Mould isn’t always easy to spot. It can grow in damp basements, behind walls, around windows, or in areas affected by previous leaks, while a musty smell may be the only warning sign. An expert mould inspection Calgary homeowners organise will be able to detect visible mould, water issues, and possible water entry points. When a specific reason exists for investigating, mould testing Calgary can offer more information. Before hiring an expert, it is important that you are aware of what it is that you are expecting.
In this blog, we’ll cover the difference between mould inspection and mold testing Calgary, what an expert should check, when testing may be useful, Calgary-specific moisture risks, and what to ask before hiring an inspection professional.
Mould Inspection vs. Mould Testing: What’s the Difference?
A mould inspection focuses on the home and the conditions that may be contributing to mould growth. This usually includes investigating any damp areas, mould, water damage, musty smells, condensation and potential sources of dampness.
On the other hand, mould testing involves collecting air, surface, or material samples for laboratory analysis. It can be valuable if mould is not seen, if there is a suspected mould problem, or if additional information is required to determine the type and amount of a concern.
For a quick understanding of the key differences between mould inspection and mould testing, take a look at the comparison below:
| Mould Inspection | Mould Testing |
| Examines the property for mould and moisture concerns | Analyzes collected samples for additional information |
| Looks for visible mould, water damage, and damp areas | May involve air, surface, or material samples |
| Helps identify potential sources of moisture | Samples may be analyzed in a laboratory |
| Focuses on understanding the cause and extent of the concern | Used when further investigation is needed |
7 Signs You May Need a Mould Inspection in Calgary
1. A Persistent Musty Odour
If there is a musty smell that persists after cleaning, it could be because there is too much moisture or mould build-up in a less noticeable part of the house. It may be found in damp basements, wall cavities, wall insulation or other wall spaces. An odor may not be a key sign of mould, however, it’s a good sign to think about a mould inspection in Calgary if you are unable to determine its source.
2. Visible Mould Growth
If there is mould on walls, ceilings or surfaces, this is a definite indication that further investigations should be conducted. But cutting back on the growth that is visible may only be a short-term fix if the moisture is not first located. A professional mould inspection Calgary homeowners book can help you find out if there are any leaks, condensation, poor ventilation or foundation moisture that is enabling the mould to continue to grow.
3. Previous Flooding or Water Damage
When there is water damage or flooding in the past, mould can be an issue even if it may not be visible. Moisture can be trapped in materials that are not visible from basement flooding, plumbing leaks, roof leaks, and water entering through the foundation. A mold inspection in Calgary may be needed if you have experienced heavy water damage in your home to determine if there’s a need to proceed with more investigation.
4. Recurring Condensation
Excessive humidity inside the home or poor ventilation can be seen on windows, on exterior walls or other cold surfaces. This may be more apparent in Calgary’s cold winters, when warmer indoor air contacts cooler surfaces and results in moisture. If condensation persists, it is important to deal with the humidity and ventilation problem to minimise the conditions that could foster mold growth.
5. Water Stains or Discolouration
Ceilings and walls may have brown, yellow or abnormal stains that can indicate past or present water intrusion. The cause of the stain could be a roof leak, a plumbing issue or leaking from the outside. A mould inspection Calgary service can assist in determining the surrounding conditions and decide that there is further need for action or not.
6. Persistent Basement Dampness
If your basement is constantly damp, smells musty or has condensation, it is worth getting a closer look. Moisture can be drawn in from foundation walls, floor cracks, window wells or poor exterior drainage. Seasonal snowmelt, rain and freeze-thaw events in Calgary can be a concern for moisture in the foundation. It is often better to find out where the dampness is coming from than to treat the mould that can be seen.
7. Mould Keeps Coming Back
If mould keeps re-appearing after cleaning, the moisture source is likely to remain. Conditions that favour mould growth can continue to occur as long as condensation occurs or plumbing leaks occur and remain undetected, foundation seepage happens, or ventilation is inadequate. When no answer has been found to a particular question, mould testing Calgary might be considered, and a comprehensive survey can shed light on the moisture issues.
What Happens During a Professional Calgary Mold Inspection?
A mould inspection by a professional will go beyond the identification of mould growth. It aims to identify the source of moisture, the presence of mould and what conditions are enabling the mould to grow.
Step 1: Discuss the Property History
The inspector will question when the problem began, and any previous flooding, plumbing or roof leaks, renovations, musty odours, or previous mould remediation. This background can also be used to determine where attention might be needed.
Step 2: Conduct a Visual Assessment
Basements, bathrooms, attics, crawl spaces, kitchens, and damp and water-damaged areas that are accessible are checked for visible mould, stains, dampness, condensation and other indications.
Step 3: Check for Moisture
Moisture meters can be used to detect areas with high levels of moisture in accessible materials, and thermal imaging can be utilised to identify temperature variations which merit additional scrutiny. The tools can be used as aids to the inspection but cannot, on their own tell you if mould is present.
Step 4: Identify the Source
It is important to locate the source of moisture. Some reasons are: plumbing leaks, roof issues, foundation moisture, condensation, bad air circulation, high humidity. Fixing the source will prevent recurring mould growth.
Step 5: Decide Whether Sampling Is Necessary
Testing is not compulsory. Where the mould and its source is known, sampling may not be of great value. Hidden contamination may be suspected and/or there may be a specific question to be answered, in which case air, surface or bulk sampling may be considered.
Step 6: Review the Findings
There are specific things that should be included in a useful report: Areas inspected, concerns that can be seen, moisture indications, photographs if appropriate, potential sources, limits of the investigation, and recommended next steps. After a comprehensive Calgary mold inspection, you should be able to know what was discovered, what it might be caused by and what the next steps are.
What Should Be Included in a Professional Mould Inspection Report?
A good inspection report will not just confirm the presence or absence of mould. It should inform you about what you saw, where moisture may be coming from, and what should be done next. When evaluating a Calgary mold inspection company, you should compare one that provides a report that contains all of the following:
- Areas inspected: Areas inspected are the rooms, systems, and accessible areas that are inspected.
- Findings and Photographs: Documentation of visible mould, staining, water damage, or other issues.
- Moisture information: Moisture information relevant and information about areas with high moisture.
- Possible causes: Leaks, condensation, foundation moisture or poor ventilation.
- Areas of concern: An explanation of areas that need attention or investigation.
- Limitations: Any inaccessible areas or conditions that could not be fully assessed.
- Recommendations: Practical next steps – correct the moisture source, further investigation, remediation.
- Additional testing: An explanation of why or why not sampling is recommended.
Conclusion
A professional mould inspection can help uncover moisture issues before they become costly, recurring problems. The right assessment provides you with a better roadmap, from pinpointing hidden moisture sources to finding out if additional testing is even needed.
