What Influences Removal Costs?
1. Property Size & Roof Area
The total square meterage of spray foam coverage is the primary cost driver. Larger roof spaces require more labor hours, equipment, and disposal costs.
2. Foam Type: Open Cell vs Closed Cell
Closed-cell spray foam is denser and adheres more strongly to timber, making removal significantly more labor-intensive and expensive than open-cell foam.
- Open Cell: Easier to remove, lower costs
- Closed Cell: Can add 30-50% to removal costs
3. Roof Complexity & Access
Complex roof structures, limited access points, low ceiling heights, and awkward spaces all increase labor time and difficulty, raising costs accordingly.
4. Timber Condition
If spray foam has caused timber damage (rot, moisture retention), additional carpentry work and timber replacement will be required, adding £2,000-£10,000+ to the project.
5. Disposal & Waste Management
Spray foam waste must be disposed of properly. Costs typically range from £500-£2,000 depending on volume and local disposal facility charges.
6. Re-insulation
Most homeowners choose to re-insulate with lender-approved materials after removal:
- Mineral Wool: £1,500-£3,000
- Rigid Insulation Boards: £2,000-£4,000
- Natural Fiber Insulation: £2,500-£5,000
7. Certification & Survey Costs
Lender-compliant removal certification typically costs £300-£800. Some specialists include this in their quote, while others charge separately.
⚠️ Beware of Hidden Costs
Some removal companies advertise low prices but add significant costs later. Always ask about:
- Waste disposal fees
- Scaffolding or access equipment rental
- Timber repair or replacement
- Certification and survey fees
- VAT (removal work is generally VATable at 20%)
