What Is a Mold Inspection & Why Do You Need One in Calgary?

Mold is a fungus that grows wherever moisture is present. In Calgary, extreme temperature swings, ice damming, and aging housing stock create the conditions mold needs to thrive — often hidden behind drywall, inside attics, and under flooring where you cannot see it. A mold inspection locates it before it becomes a health hazard or a costly remediation project.

At CHI Home Inspections, mold investigations are performed by Cliff Keveryga and Carson Lisowski — certified mold investigators with construction backgrounds who understand how Calgary homes are built and where moisture problems develop. We follow the investigative process recommended by Canada Mortgage and Housing Corporation (CMHC) and the American Industrial Hygiene Association: visual inspection first, air sampling where required, lab analysis, and a written report with findings and next steps.

Mold affects air quality and can cause allergic reactions and respiratory illness — particularly for pregnant women, infants, the elderly, and anyone with a compromised immune system. If you suspect mold, smell musty odours, or have had recent water damage, do not wait. A professional mold inspection gives you the facts you need to act.

Mold Inspection & Testing Services We Offer

Professional mold investigation and air quality testing for Calgary homes and real estate transactions.

Mold Inspection

A certified mold investigator visually inspects your property for visible mold growth, moisture indicators, and musty odours. We identify the extent of the problem and determine whether air sampling is required.

Air Quality Testing

We collect indoor air samples using professional equipment and send them to an accredited local laboratory for analysis. Results confirm the presence, type, and concentration of mold spores in your home.

Moisture & Source Investigation

Mold needs moisture to grow. We trace active moisture sources — roof leaks, plumbing failures, foundation seepage, condensation — to identify the root cause, not just the visible symptom.

Pre-Purchase Mold Inspection

Buying a home in Calgary? A mold inspection before you commit protects you from inheriting a remediation bill. We assess the property and provide a clear report before your conditions expire.

Post-Remediation Verification

After mold has been removed, we verify the remediation was successful. Air samples confirm mold levels have returned to normal before you re-occupy the space or close a real estate deal.

Attic & Crawlspace Mold Scan

Attics and crawlspaces are Calgary's most common hidden mold locations — poor ventilation and moisture accumulation create ideal conditions. We inspect these areas specifically as part of every mold investigation.

Where Does Mold Hide in Calgary Homes?

Our certified investigators check every location where Calgary’s climate and construction create mold risk.

  • Attic sheathing & rafters
  • Basement walls & floor joists
  • Crawlspace insulation
  • Behind drywall & vapour barrier
  • Under sinks & around plumbing
  • Window & door frames
  • Bathroom caulking & grout
  • HVAC ducts & air handlers
  • Roof leak damage areas
  • Ice dam water intrusion zones
  • Ceiling tiles & insulation
  • Cardboard & stored materials
  • Humidifier & HRV components
  • Garage & attached structures
  • Foundation wall seepage points
  • Flood & water damage areas

Not sure if you have a mold problem? Musty odours, visible staining, or a history of water damage are all reasons to call.

Mold Inspection Calgary — Frequently Asked Questions

Straight answers to the questions Calgary homeowners and buyers ask most about mold testing and inspection.

A CHI mold inspection follows the process recommended by Canada Mortgage and Housing Corporation (CMHC). We start with a background investigation — history of flooding, roof or plumbing leaks, and any occupant health symptoms. We then conduct a full visual inspection for visible mold, moisture staining, and musty odours. Where mold is suspected but not visible, we collect air samples using professional equipment and send them to an accredited local laboratory for analysis. You receive a written report with findings, lab results where applicable, and recommended next steps.

A standard home inspection looks for visible signs of moisture damage and conditions that could lead to mold — but it is not a dedicated mold inspection. At CHI, we include thermal imaging on every standard inspection which helps identify hidden moisture that may indicate mold risk. If mold is suspected during a standard inspection, we recommend booking a dedicated mold investigation with air sampling for definitive results.

You should consider a mold inspection if you notice musty or earthy odours in any area of your home, visible dark staining on walls, ceilings, or grout, unexplained allergy or respiratory symptoms in occupants, a history of water damage, flooding, or roof leaks, or if you are buying or selling a home and want documented confirmation of mold-free air quality. Calgary’s climate — with significant freeze-thaw cycles and ice damming — creates specific moisture risks that make mold more common here than in milder regions.

A home inspection does not pass or fail a property — it identifies and documents conditions. If significant mold growth is found during a home inspection or dedicated mold investigation, it will be documented in the report with photos and context. What you do with that information — negotiate a price reduction, request remediation, or walk away — is your decision. The report gives you the evidence to act from a position of knowledge rather than uncertainty.

A typical mold inspection takes 1 to 3+ hours on-site depending on the size of the property and the extent of suspected mold activity. Larger homes, finished basements, and properties with a history of water damage require more time. Air samples are collected during the visit and sent to an accredited laboratory — lab results typically take 3 to 5 business days. Your written report with findings and lab results is delivered once analysis is complete.

Carson showed up early, was incredibly thorough, genuinely honest, and clearly knowledgeable. He went through every detail of his findings with me, giving tips, tricks, and practical advice along the way. The report came earlier than expected, and the free online home binder, with maintenance reminders, and all the info you’d ever need to maintain your home is a huge bonus. I highly recommend C H I to anyone looking for a thorough and trustworthy home inspector.

We had a fantastic experience with Carson Lisowski, our home inspector. He was professional, thorough, and incredibly polite and respectful throughout the entire inspection. He took the time to do a very detailed job and made sure everything was carefully checked. What really stood out was how kind and patient he was with our 3-year-old son, who was very excited to "help" with the inspection. Instead of being bothered by the interruptions, he was friendly, engaging, and made my son feel included, which we really appreciated. It's not every day you find someone who is not only excellent at their job but also genuinely great with kids. I highly recommend him to anyone looking for a knowledgeable, professional, and personable home inspector. Thank you Carson for such an outstanding experience!

I had a great experience with Cliff. He was very professional, arrived on time, and conducted a thorough inspection of my home. He took the time to explain everything clearly and answered all of my questions in a way that was easy to understand. His detailed report helped me identify several warranty issues that I was able to report to my builder. I highly recommend Cliff to anyone looking for a knowledgeable and reliable home inspector.

Carson was incredibly professional, knowledgeable, and helpful throughout the entire inspection process. As a first-time homebuyer, I had so many questions, and he took the time to answer every one of them thoroughly. He also provided valuable advice on home maintenance and what to expect over the next few years!! The inspection itself was extremely thorough, and I learned so much too. The final report was detailed, easy to understand, and useful for helping me prepare for any future maintenance or repairs. Carson was soooo kind, patient, and professional from start to finish. The entire experience was absolutely worth every penny, and I would highly recommend him to anyone looking for a reliable and knowledgeable home inspector.

Working with Carson was an outstanding experience from start to finish. He took the time to thoroughly walk me through every aspect of the inspection, patiently answered all of my questions, and made sure I understood what he was seeing and why it mattered. What stood out most was how much he genuinely cared. I never felt rushed, and it was clear that he wanted me to feel informed and confident in my home purchase rather than just checking boxes and moving on. His attention to detail, professionalism, and willingness to educate made a potentially stressful process feel manageable and even enjoyable. If you're looking for a home inspector who is knowledgeable, thorough, and truly invested in his clients, I can't recommend Carson highly enough. Thanks again for all your help!
