What's included
What Our Dry Ice Blasting Spray Foam Removal Includes
Every dry ice blasting spray foam removal job includes the survey, the removal, the clean-up and the completion report. There are no hidden extras for waste removal or paperwork. If your property needs extra work, such as new insulation batts or a vapour barrier, we quote that separately and in writing before we start.
Free On-Site Survey
We visit, measure the foam coverage, identify open cell or closed cell spray foam, and check the roof void for condensation and roof rot. You get a written fixed price the same day, with photos of everything we found.
Full Dry Ice Removal
Complete removal of foam from rafters, felt, battens and tiles using the dry ice blasting machine, oscillating multi-tool and reciprocating saw. We work at -78.5C to protect timbers and vapour barrier membranes.
Dust Extraction and Clean-Up
Negative-pressure dust extraction runs throughout, and we bag every scrap of foam waste for removal. Dust sheets protect your floors and stairs, and we vacuum the loft before we leave. Your home is left clean.
Moisture and Thermal Check
We run a thermal imaging camera and moisture meter across the timbers and roof void, then record the readings in your report. This is the evidence surveyors and lenders want to see before they sign off.
Completion Report
A dated document with before-and-after photos, moisture readings and ventilation notes. It is written for lenders, surveyors and building control, and it is the reason most of our London customers can complete a sale or remortgage.
Service overview
What Dry Ice Blasting Spray Foam Removal in London Involves
Dry Ice Blasting Spray Foam Removal in London uses compressed pellets of solid CO2 fired at -78.5C to freeze and shatter polyurethane foam on contact. The foam cracks off the timber, tiles and felt without heat, water or abrasive grit, so rafters, battens and vapour barriers survive intact. We pair the dry ice blasting machine with an industrial vacuum and dust extraction unit, then hand-finish corners with an oscillating multi-tool and reciprocating saw where the foam is thickest.
London homeowners call us when a surveyor flags spray foam and the mortgage lender refuses to proceed. Loft condensation, roof rot from trapped moisture and damp and mould growth are the usual culprits, especially in period terraces across Camden, Islington and Hackney. If you need dry ice blasting spray foam removal in London near me, we survey first, then quote a fixed price before any work starts. We have been trading since 2022 and have cleared hundreds of London lofts.
How we workWe verify the cause, compare realistic options, and confirm the repair before we leave.
The service timeline
Our Dry Ice Blasting Spray Foam Removal Process
The process flexes to the condition, but these checkpoints keep decisions clear.
Free Survey
We visit your property, measure the foam coverage, check the roof void for condensation and photograph the timbers. You get a written fixed price the same day, usually within four hours of the visit. Surveys across London and Greater are free, including evenings and weekends.
Site Protection
On arrival we lay dust sheets, seal loft hatches and set up negative-pressure dust extraction. Our technicians wear PPE respirators and full suits. On a typical Westminster townhouse this setup takes 45 minutes and keeps foam dust out of your living space.
Dry Ice Blasting
We feed CO2 pellets through the dry ice blasting machine at 150 to 200 psi and work methodically across the rafters. Foam freezes, cracks and falls into the vacuum. A 50 square metre loft takes six to eight hours with a three-man crew.
Detail and Hand-Finish
Corners, nail heads and tight rafter gaps get hand-finished with an oscillating multi-tool and spray foam cutting tools. We check every bay with a thermal imaging camera and moisture meter so no hidden pockets of foam or damp timber are missed.
Clearance and Report
We bag all waste, vacuum the loft clean and remove everything through the hatch. You receive a dated completion report with before-and-after photos, moisture readings and ventilation notes, ready to send to your lender or surveyor.
Tools & methods
Tools and Methods We Use
Purpose-built equipment, used by trained technicians, so the job is done accurately the first time.
Dry Ice Blasting Machine
Fires CO2 pellets at -78.5C and 150 to 200 psi to freeze and shatter spray foam without heat, water or abrasive grit. It is the core of every removal we do.
Industrial Vacuum and Dust Extraction Unit
Captures foam fragments and dust at source. Negative pressure keeps the loft and the rest of your home clean, which matters in London flats and terraces.
Oscillating Multi-Tool and Reciprocating Saw
Hand-finishes corners, nail heads and tight rafter gaps where the blasting machine cannot reach. We use spray foam cutting tools to trim thick sections without gouging timber.
Thermal Imaging Camera and Moisture Meter
Checks every bay for hidden damp and missed foam. Readings go into your completion report as evidence for surveyors and lenders.
PPE Respirator and Full Suits
Protects our technicians from isocyanate dust and airborne foam particles. We also seal your loft hatch and lay dust sheets before any work starts.
Use cases
When to Book Dry Ice Blasting Spray Foam Removal
These examples show how the service framework adapts rather than forcing every call through one repair.
Croydon Loft Cleared of Damp and Mould
A semi-detached house in Croydon had open cell spray foam across the roof void and mould growing on the ceiling below. The owner had tried scraping it by hand and damaged two rafters in the process. → Dry ice blasting removed 42 square metres of foam without further damage to the timbers. We treated the mould, replaced one rotten batten and left the loft dry and ventilated. The ceiling has stayed dry for two winters.
Canary Wharf Flat Warranty Restored
A penthouse flat in Canary Wharf had foam overspray across the roof void from a poorly supervised installation. The building warranty provider refused to cover any roof defects until the foam was removed and documented. → We removed the overspray with dry ice blasting in a single day, photographed the cleaned roof void and issued a dated report. The warranty provider accepted the evidence and reinstated cover on the roof structure.
Problems we solve
London Spray Foam Problems We Fix
Spray foam causes more problems in London than most homeowners realise. Here are the four we see every week, and how dry ice blasting solves them.
Mortgage refusal due to spray foam
We remove the foam with dry ice blasting, document the roof void with photos and moisture readings, and give you a lender-ready report. Most sales unblock within two to three weeks of the foam coming out.
Loft condensation and roof rot from trapped moisture
Dry ice blasting lifts the foam without adding water or chemicals. We check every rafter with a moisture meter, identify rot, and advise on ventilation so the roof can dry out properly.
Difficulty selling property and reduced property value
We clear the foam, provide the paperwork buyers and lenders want, and leave the loft ready for compliant insulation. That removes the defect and protects your asking price.
Overheating in summer and voiding of building warranty
We remove the foam with dry ice, restore the roof void to its original specification, and document the work so your warranty provider can see the defect has been corrected.
Pricing process
Dry Ice Blasting Spray Foam Removal Costs in London
1,200 - 3,200 pounds depending on foam type, area and access
Foam Type
Open cell spray foam is softer and comes away faster. Closed cell spray foam is denser and bonded harder to timber, so it takes longer and costs more per square metre. We identify the type at the survey.
Area Covered
Price scales with square metres of foam. A 25 square metre loft starts around 1,200 pounds, while a 60 square metre roof can reach 3,200 pounds. We measure precisely so you are not paying for guesswork.
Access and Roof Type
Shallow lofts, single hatches and restricted roof access in period London terraces take longer. Easy-access lofts in Croydon and Bromley are quicker and cheaper to clear.
How much does dry ice blasting spray foam removal cost in London?
Most London lofts cost between 1,800 and 3,200 pounds in 2026, depending on foam type, area and access. A small 25 square metre loft with open cell spray foam starts around 1,200 pounds. Closed cell spray foam, roof-level access and heavy overspray push the price up. Every quote is fixed after a free survey, so you know the number before we start.
Do you offer dry ice blasting foam extraction in London Greater?
Yes. We cover all 32 London boroughs plus the City of London, from Hillingdon to Havering and Barnet to Croydon. Our crews carry the dry ice blasting machine, industrial vacuum and dust extraction unit on every van, so we can work in flats, terraces, semis and warehouses. Most jobs are booked within 48 hours of your survey.
Is dry ice blasting spray foam removal covered by insurance in London?
Sometimes. If the foam was installed by a previous owner and caused roof rot, damp and mould growth or structural timber damage, your buildings insurer may cover part of the removal. We provide a dated report with photos and moisture readings to support your claim. We do not deal with insurers directly, but we give you the evidence they ask for.
How long does dry ice blasting spray foam removal take in London?
A standard 50 square metre loft takes six to eight hours with a three-man crew, so most jobs finish in a single day. Larger roofs, thick closed cell spray foam or restricted access can run to two days. You do not need to move out, and we clean up and remove all waste before we leave.
