Closed Cell Spray Foam Removal: What Home Inspectors Look For

Key Areas Evaluated by Home Inspectors

1. Condition and Integrity of Insulation

Inspectors examine spray foam insulation for signs of wear, deterioration, shrinkage, or cracking. Damaged insulation can compromise energy efficiency and increase the risk of moisture infiltration and structural issues, leading inspectors to recommend its removal.

2. Proper Installation

Properly installed spray foam should provide consistent coverage, adequate thickness, and have no noticeable gaps. Inspectors look for improper installation, which can cause reduced efficiency and potential thermal bridging. If such issues are found, removal and reinstallation may be advised.

3. Moisture and Mould Concerns

Inspectors check thoroughly for moisture penetration and mould growth within or around spray foam insulation. Moisture issues often necessitate removal to protect your home's structure and ensure healthy indoor air quality.

4. Chemical Odours and Emissions

Strong chemical smells or indications of off-gassing from insulation are red flags for inspectors. Persistent chemical odours can suggest improper curing or breakdown of the insulation, prompting inspectors to recommend professional removal to maintain indoor air quality.

5. Compliance with Building Regulations

Inspectors verify whether spray foam insulation complies with current local building codes and standards. Insulation failing to meet these regulations may require removal and replacement to ensure compliance and safety.

When Do Inspectors Recommend Removal?

Home inspectors typically recommend spray foam removal if:

• Insulation poses health risks due to mould or chemical off-gassing.
• Significant deterioration or installation issues are evident.
• Structural integrity or moisture-related concerns are identified.
• Insulation fails to meet current regulatory standards.

• Around 15% of home inspections reveal insulation-related issues, often requiring removal.
• Proper insulation can potentially increase a property's value by up to 10%.

Inspectors examining insulation are like doctors diagnosing a condition—they identify potential problems early to ensure long-term safety and effectiveness.
