How much does a stucco inspection cost before buying a home in Ottawa?

A dedicated stucco inspection before purchasing an Ottawa home typically costs $400–$900, depending on the home's size and the inspection scope. This is separate from your standard home inspection and focuses specifically on the stucco cladding system's condition — money very well spent when you're buying a stucco-clad property.

What a Stucco Inspection Covers and What It Costs

There are two levels of stucco inspection commonly available in the Ottawa market:

• Visual and invasive probe inspection ($400–$600): A qualified inspector examines all stucco surfaces for cracking patterns, staining, sealant condition, and flashing details. They then make small probe cuts (usually 1–2 inch squares) at high-risk areas — below windows, at roof-to-wall transitions, near grade level — to check for moisture damage in the sheathing behind the stucco. The holes are patched after inspection.- Comprehensive moisture survey with thermal imaging ($700–$900): Includes everything above plus infrared thermal imaging of all stucco walls and electronic moisture meter readings at multiple points. This gives a complete moisture map of the entire exterior without making as many invasive cuts. This is the better option for EIFS (synthetic stucco) homes where concealed moisture problems are more common.

A standard home inspector will note visible stucco cracks or damage but won't probe behind the surface or use moisture detection equipment. Since the most expensive stucco problems — rotted sheathing, mould behind walls, structural damage to framing — are invisible from outside, the standard inspection misses exactly the issues you need to know about.

For Ottawa homes, I'd particularly recommend a stucco-specific inspection in these situations:

• Any home with EIFS/synthetic stucco installed before 2005 (early EIFS systems had poor moisture management)- Homes where stucco meets a different cladding material (transition points are failure-prone)- Properties showing any staining below windows or at roof-wall junctions- Homes over 15 years old with original stucco and no documented maintenance history

The reason this inspection pays for itself: concealed moisture damage behind stucco can cost $15,000–$60,000+ to remediate, depending on how far it has spread. Discovering this before you buy lets you negotiate the purchase price accordingly, request repairs as a condition of sale, or walk away entirely. A $600 inspection that reveals $30,000 in hidden damage is the best return on investment you'll ever see in real estate.

Finding a qualified stucco inspector in Ottawa requires some diligence. Look for inspectors with specific experience in exterior cladding assessment — not just general home inspectors who also "do stucco." Ask about their training, equipment (they should own a professional-grade moisture meter and thermal camera), and how many stucco-specific inspections they perform annually. A good stucco inspector should provide a detailed written report with photos, moisture readings, and repair cost estimates within 3–5 business days.
