At Open Cell Spray Foam Removal, we specialise in the safe and thorough extraction of open cell spray foam insulation from a wide variety of building structures across the UK.

Whether you’re facing challenges due to overapplication, moisture retention, or preparing your property for renovation or sale, our experienced team ensures complete and careful removal without compromising the surrounding materials.

By resolving these issues promptly, we help improve your property’s performance, ensure compliance with relevant building standards, and make the space ready for new insulation solutions.

Why Is Open Cell Spray Foam Difficult To Remove?

Open cell spray foam can be difficult to remove due to its sponge-like texture and deep penetration into surfaces like wood, plasterboard, and roof membranes. Although less dense than closed-cell foam, it expands more during application, often filling cavities and bonding tightly to substrates.

Effective removal requires precision and specialised tools to avoid damaging the materials beneath and to ensure all foam is extracted from tight or enclosed areas.

What Are The Common Reasons For Open Cell Spray Foam Removal?

Open cell spray foam may need to be removed for a number of reasons, including:

• Improper Installation – Over-expansion or poor application reducing insulation performance
• Moisture Concerns – Absorption of moisture leading to mould, rot, or indoor air quality issues
• Access for Repairs – Removal required to carry out structural or electrical work
• Airflow Obstruction – Excess foam affecting attic ventilation or airflow systems
• Regulatory or Lending Issues – Foam that doesn’t meet building codes or lender requirements

How Much Does Open Cell Spray Foam Removal Cost?

The cost of open cell spray foam removal ranges between £1.50 and £3.50 per square foot, depending on the thickness and application method. Additional costs may arise if removal reveals underlying damage requiring repairs.

How Is Open Cell Spray Foam Removed?

The open cell spray foam removal process starts with a detailed inspection to understand the foam’s spread and any access limitations. The work area is prepared by isolating the space, protecting surrounding materials, and ensuring adequate ventilation.

Removal is carried out using a combination of mechanical tools such as scrapers, vacuums, and oscillating saws, tailored to the foam’s lightweight but expansive nature. Debris is carefully extracted, and the surface is cleaned and repaired to allow for new insulation installation.

How Long Does It Take To Remove Open Cell Spray Foam?

Open cell spray foam removal can range from several hours to a few days depending on the coverage area, depth of foam penetration, and ease of access.

Smaller installations, such as attic joists or between stud walls, may be completed in a day, while more extensive applications may require additional time for complete removal.

Is Open Cell Spray Foam Removal Safe?

Open cell spray foam removal is safe when performed by trained professionals following proper procedures. Our team uses personal protective equipment (PPE) to prevent exposure to airborne foam particles, maintains ventilation to reduce dust buildup, and implements containment systems to isolate the work area.

We also follow strict health and safety standards, including appropriate waste handling, to ensure a safe and compliant worksite throughout the removal process.

What Happens After Open Cell Spray Foam Is Removed?

After open-cell spray foam removal, the area is thoroughly cleaned and checked for any surface damage or moisture issues. Repairs are made if necessary to restore the structural integrity of the space.

Once the area is ready, a new insulation system can be installed. We also ensure that the space is correctly sealed and ventilated to support long-term energy performance and indoor air quality.
