Open-Cell Spray Foam Removal

Open‑cell spray foam is a soft, sponge‑like insulation that expands significantly and absorbs moisture easily. When it begins to age or has been installed incorrectly, it can cling to rafters, soak up water and make it difficult to assess the true condition of the roof.

Our open‑cell foam removal service uses specialist equipment to extract the foam safely from rafters, lofts and roof structures. We remove the material without damaging the timbers, restore airflow and leave the space clean, breathable and ready for modern, compliant insulation.

Open‑cell spray foam is known for causing moisture and ventilation issues, which is why it is frequently flagged during surveys and can lead to mortgage delays or refusals. Its absorbent texture can hide early signs of damp, mould or timber decay, making it difficult for surveyors to inspect the roof properly.

Key issues include:

• Moisture being absorbed and held within the foam
• Water becoming trapped against rafters and timbers
• Damp, mould and early timber decay being concealed
• Surveyors unable to assess the roof condition
• Frequent mortgage concerns or refusals
• Roof deterioration going unnoticed

Because open‑cell foam is messy, absorbent and often bonded deep into the rafters, safe removal requires specialist tools and controlled techniques. Professional extraction ensures the foam is removed cleanly, airflow is restored and the loft becomes safe, dry and ready for new insulation that meets current standards.
