Eliminate Your Open-Cell Spray Foam Problem

Are you one of the thousands of UK homeowners who placed your trust in spray foam insulation only for it to turn into a nightmare? While spray foam insulation has been around for decades – and can be highly effective when professionally installed and used in the right circumstances – spray foam insulation drawbacks are possible when poorly installed or used in inappropriate situations.

While previously championed and promoted by the government via various grant schemes to encourage households to have it installed, spray foam comes with serious drawbacks, raising concerns for homeowners, buyers and lenders. Much of this caution is due to the insulation’s impact on the property’s integrity and value.

If you’re considering having your open-cell spray foam insulation removed, the good news is that it is usually far more straightforward to remove than a closed cell spray foam removal alternative, which is a more dense and rigid material. Thankfully, open-cell spray foam doesn’t turn brick solid, instead remaining soft and malleable after curing, meaning it usually can be removed easily with professional help using specialised tools and techniques.

Reasons to Remove and Replace Your Open-Cell Spray Foam Insulation

There are many reasons to remove your spray foam insulation…

Challenges With Mortgage and Home Sales

If you’re one of the estimated 250,000 homes in the UK with spray foam insulation and are looking to refinance or sell, you would be well advised to remove it. Spray foam is a problem for mortgages as it makes it difficult for surveyors to inspect a property’s timber condition. Banks and other lenders consider this uncertainty a significant risk, meaning they may not lend money in these circumstances. Surveyors will also often down-value properties that have spray foam insulation.

Moisture Issues

Unlike closed-cell insulation, open-cell, as its name indicates, is porous and allows moisture and air to move through it. While the insulation’s ‘breathability’ can be beneficial in some situations, it also runs the risk of absorbing and trapping water from leaks, condensation, or high-humidity climates. If left unchecked, stagnant moisture in the insulation material can affect energy efficiency and cause premature rotting of wooden components in the roof of wall structures.

Air Quality and Serious Health Risks

Degradation or improper installation of spray foam insulation can release chemical fumes, known as off-gassing, with volatile organic compounds (VOCs) from the insulating material, posing a potential risk to health. Those already suffering from asthma and other allergies may experience worsened symptoms.

Impact on Structural Integrity

While open-cell spray foam rarely causes direct structural issues, improper application can still create issues for homeowners. Spray foam can expand over 100 times its liquid state meaning that uneven application can put unintended pressure on your roofing tiles and slats, causing them to lift or become misaligned. Additionally, the foam insulation could block crucial ventilation points in your loft, trapping heat and building up humidity. While newer types of SPF have been treated to resist heat, older spray foam materials can present a fire hazard that requires replacement.

Difficulties With Future Repairs

For people planning to remodel or renovate, both closed and open-cell SPF can turn the project into a nightmare. The foam adheres tightly to its surroundings, so it’s practically impossible to carry out repairs without clearing the insulation. It also makes identifying damage more challenging for your contractor.

How to Spot Signs of Problematic Open-Cell Spray Foam Insulation?

Several warning signs could indicate issues in your property’s spray foam insulation. One red flag to watch out for is a persistent presence of moisture or condensation.

If you notice visible damp patches or water stains on your walls and ceilings, you could be dealing with a serious underlying issue. Musty smells and mould growth spell similar excess moisture problems.
Cracking, shrinking, and poor adhesion to the surrounding materials suggest improper spray foam application.

How Do Professionals Remove Open-Cell Spray Foam?

As it remains somewhat soft, an open-cell spray foam installation is usually much easier to remove and replace than closed-cell insulation. That said, removing spray foam is still a messy and labour-intensive job.

Removal companies will begin by assessing the type of spray foam insulation applied to the space as well as the surrounding roofing or walling structure, with a plan drawn up for the safest access and removal.

The technician will start by cutting the foam into smaller pieces using hand tools. This allows careful removal without damaging surrounding timber, tile, or membrane. Dry ice blasting can be used in some circumstances while oscillating multi-tools, saws and wire brushes can be used to remove stubborn residue.

Personal protective equipment (PPE) such as safety face mask, goggles, gloves, and protective clothing is worn at all times to avoid inhaling potentially toxic fumes and foam particles. The workspace should be well ventilated during the removal process to reduce exposure to dusty and fumes.

Once cleared, they inspect the roofing structure for any undetected moisture damage, rotting, and other issues that need immediate attention. Additional services are often offered to restore structural damage.
Accredited insulation removal contractors will provide a completion certificate to serve as documentation for UK lenders and surveyors and help restore mortgage eligibility. Depending on the size, the entire procedure could take anywhere from one day to one week.

Several factors affect the cost to remove open-cell foam. Open-cell spray foam is typically cheaper to remove than closed cell foam because it’s porous and therefore easier to remove.

Many technicians charge per square metre, usually £20 to £50. With that, you can expect to pay about £2,000 – £8,000 for an average-sized home. Larger and more complex projects can go up to £15,000, and that can often be before taking into account costs of repairing roof timbers and other materials . 

Other aspects that impact service cost include location, accessibility of the loft space, and depth of foam. Some contractors may charge extra for proper disposal of debris.

Swapping out old spray foam insulation can help increase your property’s resale value. Sheep wool and blown cellulose can be a cheap insulation alternative to spray foam that mortgage lenders and buyers tend to be more approving of.

Finding A Spray Foam Removal Service You Can Trust

You might be tempted to opt for DIY removal of the open-cell spray foam instead of professional removal. While open cell foam can be somewhat easier to remove than closed cell spray foam, DIY insulation removal can still be difficult and, worse, lead to further property damage and more expense.
