Loft foam insulation removal with dry ice blasting
Dry ice blasting to remove loft spray foam insulation from roof timbers and loft spaces.
Safe, non-destructive clean that restores visibility across the roof structure.
No water, no harsh chemicals, and no abrasive media.
For properties that need clear timber access for surveys, roof works, refurbishment, or sale prep.
Dry ice blasting throughout the UK
We work nationwide across the UK for –
- Homeowners
- Landlords
- Developers
- Surveyors
- Commercial and industrial sites
Residential & industrial properties
We work across homes, commercial buildings, and industrial properties. We adapt the approach to match –
- Roof construction and timber types
- Access limits and working height
- Foam thickness and adhesion
Working alongside other contractors
We work alongside roofing teams, surveyors, structural engineers, and builders. Our work slots into wider remediation, refurbishment, and inspection projects, keeping the programme moving.
Antifungal treatment and certification
After removal, we apply an antifungal treatment to exposed timbers and substrates. This reduces the risk of mould and fungal growth and supports future inspections. We supply certification on completion where your project needs it.
Why loft spray foam causes problems
Surveyors often need a clear view of timbers during a purchase or remortgage. Spray foam bonded to rafters can block inspection and reduce ventilation. Some lenders take a cautious view when foam hides timber condition or increases moisture risk.
This situation often leads to one of these outcomes –
Mortgage refusal
A requirement for full insulation removal before lending
A request for specialist reports
This has made foam insulation removal increasingly necessary for property sales and refinancing.
Open-cell vs closed-cell foam removal
Each of these foam types present different challenges to roof spaces –
Open-cell foam
- Softer, spongy texture
- Allows limited air and moisture movement
- Expands deeply into timbers
- Still hides timber condition and may hold moisture over time
Closed-cell foam
- Dense, rigid structure
- Acts as a vapour barrier
- Bonds strongly to timbers and roof coverings
- Restricts ventilation and makes inspection far harder
Closed-cell foam often carries higher risk because it traps moisture against structural elements.
Common damage and risks
Loft spray foam insulation often links to property issues such as:
Trapped moisture that leads to rot in rafters and battens
Hidden timber decay because foam blocks inspection
Condensation build-up from restricted airflow
Reduced roof lifespan
Delays to sales and remortgages
Higher remediation costs when issues stay hidden
By removing the insulation, roof timbers can breathe again and be properly assessed by surveyors and contractors.
A clean, controlled removal process
Our dry ice blasting loft insulation removal process works in two clear stages for speed and control.
Stage 1 – bulk removal
We cut and remove foam in large sections where adhesion and condition allow. This reduces volume fast and speeds up the overall job.
Stage 2 – residue and detail cleaning with dry ice blasting
We dry ice blast the remaining foam residue from rafters, battens, and roof decks. This –
- Removes stubborn foam traces from timber
- Restores visibility across the roof structure
- Leaves a cleaner finish for surveys and follow-on works
Ice blasting equipment matched to the job
We bring a range of dry ice blasting systems to suit different foam types, roof structures, and access limits. We set the kit up to remove foam effectively while protecting the underlying materials.
Send us your property location, roof type, and foam type – plus photos where possible. We’ll quote and plan the safest route to clean, inspectable timbers.
FAQs
Do you remove both open-cell and closed-cell spray foam?
Yes. We tailor the method and settings to the foam type and the roof structure.
Do you work on residential, commercial, and industrial buildings?
Yes. We work across homes, commercial buildings, and industrial sites nationwide.
Will dry ice blasting damage roof timbers?
Dry ice blasting removes residue without abrasive media, so it protects timber far better than aggressive mechanical methods. We also set pressure and flow to match the surface.
Do you work with surveyors and roofing contractors?
Yes. We coordinate with surveyors, roofing teams, structural engineers, and builders so your wider project keeps moving.
Do you supply antifungal treatment and certification?
Yes. We apply antifungal treatment after removal and supply certification on completion where your project needs it.
Will foam removal help with mortgage and remortgage issues?
Foam removal restores visibility and access for inspection, which supports survey requirements and lender decisions. We also leave the roof structure cleaner for specialist reporting.
