Cheltenham's housing stock includes many Regency terraces and Victorian semis where spray foam was applied directly to rafters in the 1980s and 1990s. Dry ice blasting removes this material at -78 °C without abrasion, preserving the original timber while avoiding the dust and vibration that rotary tools create in confined lofts. The process also reduces the risk of disturbing asbestos-containing artex ceilings common in post-war extensions around Up Hatherley and Prestbury.
Gloucestershire winters bring prolonged damp periods that allow moisture to become trapped behind closed-cell foam. Once the insulation is stripped, rafters and felt must be inspected for rot before new ventilation is installed. Dry ice leaves no residue, so any water ingress points become immediately visible rather than masked by cleaning solvents or mechanical scraping.
Homeowners in the Cheltenham area often discover that foam has bridged the eaves, blocking the airflow required by current building regulations. Dry ice blasting reaches these tight junctions without enlarging the access hatch, which is frequently too small for larger equipment in period properties near the town centre.
Technician insight
In Cheltenham, the thing that catches most people out with dry ice blasting spray foam removal is how often the foam has been applied right up to the eaves in Victorian terraces, completely blocking airflow; once removed you suddenly see the full extent of felt decay that the insulation had hidden for years.
Eaves Blockage in a Montpellier Terrace
Persistent condensation stains appeared on ceilings in a 1890s terrace. Inspection showed foam bridging the eaves and trapping moisture against the rafters. Dry ice blasting cleared the foam cleanly without enlarging the small access hatch. Restored eaves ventilation eliminated the damp within one winter season.
How it works
- 1
Site Assessment
Survey the loft, note timber condition, check for asbestos and measure access constraints typical of Cheltenham terraces.
- 2
Protection Setup
Seal the living space below and position extraction to contain CO2 and dislodged foam particles.
- 3
Dry Ice Blasting
Apply pellets at controlled pressure to lift foam from rafters and felt without scoring historic timber.
- 4
Clearance and Inspection
Remove debris, inspect for hidden rot or water marks, and advise on ventilation upgrades.
- 5
Final Handover
Provide written report and photographs for the homeowner's records.
Pricing
Upfront quotes issued after on-site inspection; final price depends on loft size, foam thickness and access difficulty.
