Spray Foam Loft Insulation Removal Costs: A Comprehensive Guide

Types of Spray Foam Insulation

There are two main types of spray foam insulation commonly used in lofts, each with different properties and implications for removal:

  1. Open-Cell Spray Foam:

    • Characteristics: Soft, flexible, and permeable to moisture.
    • Density: Less dense, making it easier to remove.
    • R-Value: Approximately 3.5 per inch.
    • Uses: Suitable for soundproofing and insulation where moisture control is not critical.

  2. Closed-Cell Spray Foam:

    • Characteristics: Rigid, dense, and acts as a moisture barrier.
    • Density: More dense, making removal more challenging.
    • R-Value: Approximately 6-7 per inch.
    • Uses: Ideal for areas requiring strong moisture resistance and higher insulation values.

Costs of Removing Spray Foam Insulation

The cost to remove spray foam insulation from a loft can vary widely depending on several factors, including the type of foam, the area covered, and the complexity of the job.

Average Costs:

  • Open-Cell Foam Removal: £20-£30 per square metre.
  • Closed-Cell Foam Removal: £30-£50 per square metre.

Additional Factors Affecting Costs:

  • Accessibility: Hard-to-reach areas or confined spaces can increase costs.
  • Thickness of Foam: Thicker foam layers take longer to remove, increasing labor costs.
  • Condition of Roof: Any damage to roof timbers or structural components can add to the repair costs.

Example Costs for a 100m² Loft:

  • Open-Cell Foam: £2,000-£3,000
  • Closed-Cell Foam: £3,000-£5,000

Work Involved in Removing Spray Foam Insulation

Removing spray foam insulation is a complex and labor-intensive process that typically involves the following steps:

  1. Initial Assessment:

    • A professional team inspects the loft to evaluate the type of foam, its thickness, and the area it covers.
    • They check for any structural damage or issues with moisture that might have resulted from the insulation.

  2. Preparation:

    • Setting up safety equipment, including respirators, gloves, and protective clothing.
    • Ensuring proper ventilation to manage foam particles and chemical fumes.

  3. Foam Removal:

    • Using specialized tools such as saws, scrapers, and vacuums, professionals cut and remove sections of the foam.
    • For closed-cell foam, more effort and stronger tools may be required due to its rigidity.

  4. Cleanup:

    • All debris and foam particles are carefully cleaned up and removed from the site.
    • Final inspection to ensure all foam has been removed and the loft is in good condition.

Time Required for Removal

The duration of the removal process depends on various factors, including the type of foam and the loft's size:

  • Average Time Frame: 1-3 days.
  • Team Size: Typically requires a team of 2-4 professionals.

Hazards and Safety Concerns

Removing spray foam insulation involves several hazards:

  • Chemical Exposure: Risk of exposure to toxic chemicals present in the foam.
  • Dust and Particles: Inhalation of foam particles and dust can cause respiratory issues.
  • Structural Damage: Potential for damaging roof timbers or other structural elements during removal.

Safety Measures:

  • Professionals use protective gear such as respirators, gloves, and goggles.
  • Adequate ventilation is maintained throughout the process.
  • Proper training and experience are crucial to safely handle and remove insulation materials.

DIY vs. Hiring a Professional

While DIY removal may seem cost-effective, it poses significant risks:

  • Complexity: Removing spray foam requires specialized tools and expertise.
  • Health Risks: Exposure to harmful chemicals and dust without proper protective gear.
  • Potential Damage: Risk of damaging the loft’s structure or roofing components.

Hiring a Professional:

  • Pros: Ensures safe, efficient, and thorough removal with minimal risk of damage.
  • Cons: Higher upfront cost but mitigates long-term risks and potential repair costs.

Mortgage and Selling/Buying Property with Spray Foam Insulation


  • Some lenders may have concerns about spray foam insulation, particularly closed-cell foam, due to potential issues with moisture and structural integrity.
  • It's crucial to disclose the presence of spray foam insulation to your mortgage provider.

Selling a Property:

  • Spray foam insulation can be a selling point for energy efficiency.
  • However, it may also raise concerns for buyers regarding potential roof damage and mortgage complications.
  • Providing documentation of professional installation and adherence to building regulations can alleviate concerns.

Buying a Property:

  • If purchasing a property with spray foam insulation, consider having an independent inspection to assess the condition of the roof and insulation.


Removing spray foam insulation from a loft involves significant costs, labor, and potential hazards. Professional removal is highly recommended to ensure safety and efficiency. Understanding the implications for mortgages and property sales is essential for homeowners considering installation or removal of spray foam insulation. Always consult with certified professionals and inform relevant parties to make informed decisions.

I highly recommend these guys who recently helped us clear and clean out our loft in Newcastle after we had rodents in. They removed old junk and the old insulation then cleaned up the rodent droppings and hoovered the loft out. They were very friendly, made sure no dust and dirt got into our home and cleaned up after themselves. We are elderly people so we couldn't do this but they did everything in half a day. We tried all over to get someone to do the works for us but these guys were the only ones to come out and give us a qoute. Would use again if we ever have another rodent problem.

We used this company a couple of days ago and are really impressed with the overall service provided. The lads were here almost 4 and a half hours completely clearing the loft and cleaning it afterwards. They used coverings on the stairs and landing to keep the carpet clean. Our loft looks like a new loft now and we didn't realise just how big it is with all the rubbish removed. Great set of lads, would highly recommend this company. 👍

Fantastic service by the team of lads that came to remove my old insulation. They also removed old wood that was there at a very reasonable price and made sure there was no mess. Turned up when they said they would, very polite and professional. Would definitely recommend.
