How much does spray foam removal cost?
Eco Spray Foam Insulation removes spray foam from lofts and roofs across Orpington, Bromley and Kent. Here is what removal costs.
Updated 8 November 2026. Prices are our rates and published UK estimates, not a quote.
The short answer
Our spray foam removal costs £45 per square metre for open-cell foam and £85 per m² for closed-cell foam. Published UK guides put removal at about £40 to £80 per m², and the House of Commons Library cites around £3,200 for the roof of a three-bedroom detached house.
The figures below are our own rates plus published UK ranges, checked on 7 and 8 November 2026. They are not a quote: you get a fixed price after a free survey.
Our spray foam removal prices
| Foam type | Price per m² |
|---|---|
| Open-cell spray foam | £45 |
| Closed-cell spray foam | £85 |
The price is per square metre of foam removed. We measure the sprayed area at the survey, and the quote says which type of foam you have.

Open-cell or closed-cell?
Open-cell foam is soft and spongy. It cuts away from the rafters fairly easily, which is why it costs less to remove.
Closed-cell foam sets hard and bonds tightly to the timber. It takes much longer to strip, and the rafters need more cleaning afterwards, so it costs more.
If you are not sure which you have, we can tell at the survey.
A worked example
Removing foam from a 50 m² roof:
- Open-cell: 50 × £45 = £2,250
- Closed-cell: 50 × £85 = £4,250
If you then want standard loft insulation fitted, 300mm of mineral wool across a 40 m² loft floor is 40 × £30 = £1,200.
What pushes the price up?
The type of foam makes the biggest difference: closed-cell costs almost twice as much to remove as open-cell at our rates.
The area matters next. Foam sprayed across the whole roof, or on walls as well as rafters, means more square metres.
Access can slow the job down. Low headroom, small hatches and stored belongings all add time.
Refitting insulation afterwards is a separate cost, from £10 per m² for mineral wool.
How removal works
We survey the roof, measure the sprayed area and check the foam type. On the day, we protect the house below the loft, cut the foam away from the rafters, clean the timbers, bag the waste and take it away. We can then fit standard loft insulation so the house is not left cold.
