A Comprehensive Guide to Insulation and Waterproofing Costs in Montreal by Maçonnerie Montréal

Factors Affecting Insulation and Waterproofing Costs

When determining the cost of insulating and waterproofing a brick wall or masonry in Montreal, several factors come into play, including:

  • Size of the area: Larger areas typically have higher costs due to increased material and labor requirements.
  • Material selection: Different materials have varying costs, with more premium options generally being more expensive.
  • Building age and condition: Older buildings may require additional preparation or repairs, increasing the overall cost.
  • Accessibility: Difficult-to-access areas may require specialized equipment or additional labor, raising the cost.

Costs of Insulation Materials

There is a range of insulation materials available, each with its own cost implications:

  • Rigid foam insulation: Polystyrene expanded (EPS) and extruded (XPS) insulation panels typically cost between $1.50 and $4 per square foot.
  • Spray foam insulation: Open-cell spray foam costs around $0.45 to $0.65 per board foot, while closed-cell spray foam is more expensive, ranging from $1 to $1.50 per board foot.
  • Mineral wool insulation: This fire-resistant insulation material typically costs between $0.70 and $1.10 per square foot.

Costs of Waterproofing Materials

Like insulation materials, waterproofing materials also have a range of costs:

  • Silane/siloxane sealants: These penetrating sealants generally cost between $0.15 and $0.50 per square foot.
  • Elastomeric coatings: These flexible, waterproof coatings usually range in price from $0.50 to $1.50 per square foot.
  • Cementitious waterproofing: Cement-based waterproofing mixtures typically cost between $0.35 and $0.75 per square foot.
  • Bituminous membranes: Asphalt or modified bitumen waterproofing membranes usually cost between $1 and $3 per square foot.

Labor and Installation Costs

Labor costs for insulation and waterproofing projects in Montreal vary depending on the complexity of the job and the skill level of the professionals involved. On average, expect to pay between $40 and $75 per hour for masonry professionals, such as those at Maçonnerie Montréal. The total labor cost will depend on the size of the project, the time required, and the specific materials used.

Additional Cost Factors

Keep in mind that there may be additional costs associated with your insulation and waterproofing project, such as:

  • Permits and inspections: Depending on the scope of the project, you may need to obtain permits and schedule inspections, which can add to the cost.
  • Preparation and repairs: If your brick wall or masonry requires cleaning, repairs, or other preparatory work before insulation and waterproofing, this will increase the overall cost.
  • Disposal of old materials: If existing insulation or waterproofing needs to be removed and disposed of, there may be additional fees involved.
