Should You Remove Spray Foam If You’re Not Selling?

May 4, 2025

Most of the headlines around spray foam insulation are about one thing: blocked house sales. But what if you’re not moving? What if you’re staying put for the foreseeable future?

You might assume the spray foam in your loft isn’t an issue — and in some cases, that’s true. But there are still plenty of reasons why UK homeowners are choosing to remove it even when they’re not selling.

Here’s what you need to consider if you’re living with spray foam long term.

1. It Can Still Trap Moisture

One of the biggest risks of spray foam is its airtight seal. Especially in older homes with clay tiles or no roof membrane, this can trap condensation behind the foam — leading to:

  • Timber rot
  • Mould and mildew
  • Hidden damp patches you can’t see

Even if everything looks fine now, these issues can develop slowly over time — and become expensive later.

2. It Can Hide Problems

Spray foam sticks directly to the wood, covering:

  • Joists
  • Rafters
  • Tile fixings
  • Nail heads

That means if there’s a leak, insect activity, or weakening timber, you might not notice until it’s too late. We’ve removed foam in homes where structural damage had gone undetected for years — simply because no one could see behind it.

3. It Affects Future Plans

Even if you're not selling today, spray foam can impact:

  • Remortgaging
  • Equity release
  • Passing your home on to children
  • Letting or refinancing the property later

Removing it now — on your terms — avoids dealing with it under time pressure later when a valuation or application is at stake.

4. It’s Not Always Doing Its Job

Some older spray foam installations were done:

  • Without proper ventilation
  • Over dirty or damp surfaces
  • By sales-led teams with no long-term plan

If it wasn’t installed properly, it might not even be insulating well. We often replace foam with modern, breathable insulation that performs better, without all the risks.

5. Peace of Mind Has Value Too

Many of our customers say they just want to know:

  • Their roof is dry and healthy
  • Their insulation is compliant and breathable
  • They won’t run into problems down the line

That reassurance matters — especially in older properties or family homes you want to protect long-term.

Final Thoughts

You don’t have to be selling your home to justify removing spray foam.

If it’s trapping moisture, hiding issues, or making you second-guess the condition of your roof, it may be worth sorting now — before it becomes a bigger problem.
