Spray foam removal in a converted loft in Sheffield
In July 2026 our team removed 40m² of open cell spray foam from a converted loft in Sheffield, South Yorkshire. The foam had been put in about five years earlier and the owner was selling. We stripped out the inside of the loft room, took the foam back to the original timbers, fitted new insulation and lined the ceiling again. The work took 3 days.
Before and after: open cell foam removed from the roof of the loft roomBefore and after: foam stripped back to the original timbersAfter: the ceiling lined again with new plasterboard
What we found
The loft had been converted into a room, and open cell spray foam had been sprayed under the roof about five years before. The owner was selling. Many lenders and surveyors are cautious about spray foam because it hides the roof timbers, so they can't check their condition.
Because the room was lined, the foam could not be reached from inside without first taking the lining down.
What we did
Stripped out the inside lining of the converted loft
Removed 40m² of open cell spray foam, back to the original timbers
Fitted new insulation
Fitted a polythene vapour control layer with taped joints
Lined the ceiling again with new plasterboard
The result
The foam is gone and the roof timbers have been seen and cleared, as the before and after photos show. The room was then insulated and lined again, so the owner still has a usable loft room.
A check you can do yourself
If your loft has been converted, you can't see the underside of the roof from inside the room. Check any paperwork from when the conversion or insulation was done. If it mentions sprayed insulation, get advice before you sell, rather than waiting for a buyer's survey to find it.
