Property and insulation

Spray foam removal

Spray foam insulation was sold to many homeowners as a quick fix for heat loss. Many mortgage lenders and surveyors are now wary of it, because it covers the roof timbers and can trap moisture against them. That can make a home harder to sell, remortgage or insure. We remove spray foam carefully, so the timbers can be inspected and the loft can be insulated in a better way.

Signs you should act

  • A buyer's survey or a lender has flagged the spray foam
  • You plan to sell or remortgage
  • You see damp, mould or a musty smell in the loft
  • The foam is cracked, shrinking or coming away from the roof
  • You want the roof timbers checked

After removal

The loft will need new insulation that lets the roof breathe. We can fit it straight away. See Loft insulation. If the timbers need treatment or repair, see Raft and damp treatment.

How we remove it

  1. Survey

    Our quantity surveyor inspects the loft, measures the area and records the condition of the foam and the timbers.

  2. Quote

    You get a written price, open for 30 days.

  3. Protection

    We protect the loft hatch, the landing and the route through your home.

  4. Removal

    We take the foam off by hand and with tools that do not damage the timbers or the roof covering.

  5. Clean-up

    We bag the waste and remove it from site.

  6. Timber check

    We inspect the exposed rafters and battens and report any rot, damp or damage.

Questions

How long does removal take?

It depends on the size of the loft and the type of foam. Your quote gives a time estimate after the survey.

Will you give me evidence that the foam has gone?

Yes. We give you written confirmation of the work, which you can pass to your lender or surveyor.

Do I need to move out?

Usually not. We work in the loft and keep the rest of the house protected.
