About this service
What Dry Ice Blasting Spray Foam Removal in London Involves
Dry ice blasting spray foam removal in London uses compressed air to fire soft dry ice pellets at the foam. The pellets hit at around -78.5C, freezing the polyurethane foam so it turns brittle and flakes away from rafters, tiles and brickwork. Unlike sand blasting or grinding, dry ice leaves no secondary waste because the pellets turn straight to gas. We pair the blasting with an industrial vacuum and air scrubber to capture every particle, so your loft stays clean and your family stays safe.
Most London customers call us because a mortgage lender has rejected their property over spray foam, or because hidden damp and rot have appeared behind the insulation. The city's older housing stock, from Victorian terraces in Islington to post-war semis in Croydon, traps moisture in ways modern foam cannot handle. If you have been searching for dry ice blasting spray foam removal near me London, we cover every borough inside the M25 and can usually survey within 48 hours.

Tools & methods
Tools and Methods We Use for Spray Foam Removal
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Dry Ice Blasting Machine

Reciprocating Saw and Oscillating Multi-Tool
Used for cutting away stubborn sections of foam or trimming timber where needed. Brands include Bosch and Makita.

Real results
Before and after.
Victorian Terrace Loft in Islington
Before
A 70-square-metre loft was filled with open cell spray foam that had been applied five years earlier. The timber rafters were damp, and the homeowner's mortgage lender had refused to lend until it was removed.
After
We removed all foam with dry ice blasting in one and a half days. The rafters were clean and dry, confirmed by thermal imaging. The lender approved the mortgage two weeks later.
Post-War Semi in Croydon
Before
Closed cell spray foam covered the entire roof void of a three-bedroom semi. The foam had cracked and was letting in damp. The owner wanted it gone before putting the house on the market.
After
Dry ice blasting removed the foam in two days. We vacuumed the loft and disposed of all waste. The property was valued at 15% more than the initial spray-foam-affected valuation.
Commercial Warehouse in Barking
Before
A 500-square-metre warehouse ceiling was covered in spray foam that was failing and creating dust. The landlord needed it removed before a new tenant moved in.
After
Our team used industrial dry ice blasting equipment to clear the foam in four days. The ceiling was left clean and ready for inspection. The tenant moved in on schedule.
