Contractor insurance for draught proofing and air sealing work
Draught proofing can involve customer-property exposure, doors, windows, floors, fixings, adhesives, tools, ladders, materials and product suitability questions.
Insurance for Draught Proofing Contractors
Draught proofing insurance is for contractors fitting seals, strips, brushes, tapes, threshold products, letterbox covers, window and door draught excluders, secondary air-sealing measures and related energy-efficiency products.
The right policy should reflect whether work is carried out in domestic homes, listed buildings, rented properties, offices, schools, shops or public sector premises, and whether you provide advice, surveys or product recommendations as part of the service.
Who This Page Is For
- Draught proofing contractors, air-sealing installers and energy-efficiency trades.
- Businesses fitting door seals, window seals, brushes, tapes, strips and threshold products.
- Contractors working for homeowners, landlords, letting agents, local authorities and property managers.
- Trades carrying out minor carpentry, window, door or floor-related preparation before draught proofing.
What Cover Can Include
- Public liability for injury, accidental damage, damaged doors, windows, flooring or customer property.
- Employers' liability for employees, apprentices, labour-only subcontractors or supervised workers.
- Tools, equipment, stock, materials, adhesives, sealants, ladders and goods in transit cover.
- Contract works cover for larger retrofit or energy-efficiency projects where required.
- Products liability for supplied seals, strips, brushes, fixings, tapes and related materials.
Draught Proofing Risks
Claims can involve scratched doors or windows, damaged frames, adhesive damage, poor fitting, water ingress allegations, unsuitable products, injury from tools or ladders, accidental damage to customer possessions, and disputes where promised performance or energy-efficiency improvements are challenged.
Insurer Questions
- Do you work on domestic, commercial or listed properties?
- Do you alter doors, windows, floors, frames or glazing?
- Do you provide surveys, energy advice or product specification?
- What tools, materials and stock values need cover?
- Do you use subcontractors or work under retrofit schemes?
Customer Property and Minor Alterations
Draught proofing often happens inside finished homes and commercial premises. Public liability should be checked around accidental damage to doors, windows, frames, floors, decoration, furniture and customer possessions.
Retrofit Advice and Product Suitability
If you advise on product choice, energy efficiency, ventilation balance or property suitability, insurers may want to understand whether any professional advice exposure sits alongside the installation work.
