Dry Ice Blasting Spray Foam Removal in London
Dry Ice Blasting Spray Foam Removal in London uses frozen CO2 pellets fired at -78.5C to shrink and crack spray foam off roof timbers, brickwork and wiring without scratching the surface underneath. We handle open cell spray foam, closed cell spray foam and failed loft insulation across Greater London, usually in a single visit. If a lender, surveyor or buyer has flagged your insulation, we take it out and leave the roof ready to inspect.
Service overview
What Dry Ice Blasting Spray Foam Removal in London involves
Dry ice blasting spray foam removal London homeowners call us about is a cold, dry process. We feed rice-sized CO2 pellets through a blasting machine at roughly 150 psi. The pellets hit the foam at -78.5C, the foam turns brittle, and the gas expands underneath it. The foam lifts off in flakes instead of smearing. Because there is no water and no grit, your roof timbers, felt, tiles and cabling come out of it dry and undamaged. We then vacuum the debris into an industrial vacuum and bag it for disposal. Most London jobs we take on start with a surveyor's note or a mortgage lender refusal due to spray foam. The foam was often installed between 2010 and 2018 under a green deal scheme, and it has since trapped moisture against the rafters. That leads to roof timber rot from trapped moisture, attic condensation from spray foam and non compliant loft insulation under Building Regulations Part L. If you have searched dry ice blasting spray foam removal near me London and been quoted a full roof strip, this is the alternative.
! Common warning signs
Mortgage lender refuses to lend on a foam-insulated property
Your sale stalls, your buyer pulls out, and you may lose the chain. Lenders treat spray foam as a hidden-structure risk until the timbers have been inspected.
Roof timber rot from trapped moisture
Foam seals the roof deck, condensation cannot escape, and rafters soften over several winters. Left long enough, the roof structure needs partial replacement.
Non compliant loft insulation under Building Regulations Part L
Foam installed to old standards can fail a building control inspection, block a loft conversion, or void your home insurance if the roof later leaks.

Dry ice blasting machine
Our primary removal tool. It fires rice-sized CO2 pellets at roughly 150 psi to freeze and lift spray foam without abrading the surface underneath. Runs on compressed air with no water or grit.
Industrial vacuum and air scrubber
The vacuum captures foam flakes and spent pellets as they come off, while the air scrubber filters fine dust out of the loft air. Together they keep the rest of your home clean during the work.
Oscillating multi-tool and reciprocating saw
Used only where foam is too thick for blasting in one pass, or in tight corners. We cut controlled sections away from cables and pipework, then blast the residue off the timber.
PPE respirator and full containment kit
Every technician wears a fitted respirator, coveralls and gloves. We seal the work area with polythene and negative air pressure so no foam dust or CO2 reaches the occupied part of the building.
Local execution
London's housing stock makes spray foam removal different from anywhere else in the UK. Most of the properties we work in are Victorian or Edwardian terraces with lath and plaster ceilings, narrow loft hatches and rafters that have already spent a century holding moisture. The city's damp winters and humid summers are hard on any roof, and foam that seals the deck traps that moisture against the timber. We see the worst cases in Camden, Islington and Hackney, where green deal installers worked quickly in the 2010s. Access is the other London factor. Many lofts are reached through a 600mm hatch with no fixed ladder, so we carry compact blasting equipment and manual tools for the tight jobs. If you need dry ice spray foam extraction London-wide, we plan the route around parking restrictions and congestion charges so the crew arrives when we say. Building control across the boroughs also varies, so we keep our Part L documentation consistent and ready for any inspector.

How our spray foam removal process works

Dry ice blasting

What dry ice blasting spray foam removal costs
Dry ice blasting spray foam removal cost London Greater London homeowners ask about depends on three things: how much foam there is, what type it is, and how hard it is to reach. We quote a fixed price after a free assessment, so you know the total before we start. Typical 2026 residential lofts run from 1,200 to 3,800 pounds, and commercial roofs start around 4,500 pounds. Disposal, protection and documentation are included in every quote.
Square metres of foam
This is the biggest driver. A 30 square metre loft clears in a day and sits at the lower end of the range, while a 90 square metre roof takes three to four days and costs proportionally more. We measure on site so the quote is accurate.
Foam type and thickness
Open cell spray foam is softer and blasts off quickly. Closed cell spray foam is rigid and dense, needs slower passes and sometimes a second visit. Thick closed cell sections can add 20 to 30 percent to the job time and cost.
Access and property type
A wide loft hatch and clear floor space keep costs down. Narrow hatches, restricted parking, listed-building constraints or fragile ceilings all add labour. We assess access during the free visit and price it honestly.
Frequently asked questions
How much does dry ice blasting spray foam removal cost in London?
Typical 2026 pricing in London runs from 1,200 to 3,800 pounds for a residential loft, and from 4,500 pounds for commercial roofs. The price depends on square metres of foam, foam type, access and whether timbers need repair. We quote a fixed figure after a free assessment, so you know the total before any work starts.
Is dry ice blasting safe for spray foam removal in London?
Yes. Dry ice blasting is safe for timbers, felt, brickwork, wiring and pipework because it uses no water, no grit and no heat. The CO2 pellets sublimate into gas and leave no residue. Our technicians wear PPE respirators and ventilate the loft throughout. It is the least invasive method available for open cell spray foam and closed cell spray foam alike.
Does dry ice blasting damage surfaces in Greater London?
No. The process lifts foam without abrading the surface underneath, which is why surveyors prefer it over scraping or sand blasting. On a typical Greater London roof we remove foam from 50-year-old rafters and leave the timber grain intact. Delicate surfaces like lead flashings and old felt come through clean, and we inspect everything before we finish.
How long does dry ice blasting spray foam removal take in London?
A standard three-bedroom London loft takes one to two days, including protection, blasting, inspection and clean-down. Larger roofs or heavy closed cell foam can take three to four days. We work in pairs, so most homes are back to normal the same evening. You will get a firm schedule with your quote.
