Want peace of mind that your loft meets mortgage lending requirements and is ready for proper insulation?
If your property has previously had spray foam insulation installed, you may now need it professionally removed — whether to satisfy lender criteria, address ventilation issues, or upgrade your insulation system. Our team specialises in safely and efficiently removing all types of spray foam, restoring your roof space to a healthy, breathable, and energy-efficient condition.
At Thermoseal, we provide expert spray foam removal services across Ascot, Windsor, Camberley and the surrounding areas. Whether your property contains open-cell or closed-cell insulation, our experienced roofing contractors have the knowledge and equipment to remove it with precision and care.
Incorrectly installed spray foam can cause significant problems over time, including trapped moisture, condensation (often referred to as roof sweat), and even rot in roof timbers. These issues not only threaten the integrity of your property but can also prevent lenders from approving mortgages. Our removal service ensures your loft meets the required standards — protecting your home’s structure and making it compliant for future sales, remortgaging, or renovation work.
As a professional roofing contractor, we provide a comprehensive spray foam removal service that prioritises both safety and quality. Our experienced team is fully trained to remove both open-cell and closed-cell spray foam using a range of techniques tailored to the type of insulation present in your loft. Depending on the situation, this may involve careful manual removal, the use of a reciprocating saw, or advanced dry ice blasting technology. This tailored approach ensures the work is carried out efficiently, safely, and with minimal disruption to your property.
Once the foam has been removed, we may also clean down exposed timbers by sanding where necessary. Any remaining dust between joists is extracted using a vacuum system rather than dry sweeping, which helps prevent dust and fibres from becoming airborne. At the end of the project, all waste materials are removed from your property and taken to an approved waste facility. Our team also clears away all dust sheets and equipment, leaving your home clean and ready for the next stage of insulation.
For many projects, we use dry ice blasting as the preferred method of spray foam removal. This innovative, non-abrasive technique rapidly freezes the foam, making it brittle and easy to dislodge. As the dry ice sublimates — turning directly from solid to gas — no residue is left behind, resulting in a clean and precise finish. It’s an environmentally friendly solution that avoids the risks associated with harsh chemicals or abrasive methods and ensures your loft space is ready for compliant insulation, free from damage to delicate roof timbers, metalwork, or electrical components.
We follow strict industry best practices to ensure spray foam is removed from your loft safely and thoroughly. Our process is designed to protect both your property and our team, with safety and quality at the heart of every step.
1. Initial Inspection
Before any work begins, we carry out a full inspection of your loft space to identify the type of spray foam present and the safest removal approach. We prepare the space by laying dust sheets to protect belongings, using spreader mats and boards to evenly distribute weight over the joists if required, and ensuring the area is well lit and ventilated.
2. Safe Removal of Spray Foam
Once everything is prepared, our team begins the removal process. Depending on the type and condition of the foam, we may cut sections using a reciprocating saw or use our advanced dry ice blasting equipment for a more delicate and precise approach. We adapt our methods to suit both open-cell and closed-cell insulation, ensuring controlled and effective removal.
3. Timber Cleaning and Preparation
After the foam has been removed, we carefully clean and sand the exposed timbers to prepare the loft for new insulation. Any remaining dust is extracted using a vacuum system rather than dry sweeping, preventing fibres from becoming airborne and maintaining a safe working environment.
4. Final Cleanup and Waste Removal
Once the work is complete, we carry out a thorough clean-up of the space. All debris, waste materials, and tools are removed, along with any spreader mats and protective sheets, leaving your loft tidy and ready for the next stage of insulation.
5. Safety and Professional Standards
Throughout the process, our team wears full personal protective equipment (PPE) and works with care to avoid any damage to your property. All work is carried out by qualified, experienced professionals with extensive expertise in spray foam removal, ensuring a safe, high-quality result every time.
