About this service
What same day Spray Foam Removal in London involves
Same day Spray Foam Removal in London means we cut out, blast off, or dissolve spray foam insulation from your loft, roof, cavity, or commercial unit within hours of your call. We isolate the space with protective sheeting, run a negative air machine and air scrubber to keep dust and chemical particles out of your living areas, then remove open cell spray foam, closed cell spray foam, and polyurethane foam using the method that suits the substrate. Every load goes into sealed disposal bags and leaves site the same day.
Most London customers ring us because a mortgage lender has flagged spray foam on a survey, or because a buyer's surveyor has refused to value the property until the insulation is gone. Others call after finding loft condensation, hidden damp and rot, or roof ventilation issues that spray foam has made worse. If you need urgent spray foam removal London wide, we can usually be on site within a few hours and have the foam out before the day is over.

What's included
What our same day Spray Foam Removal includes
Every same day call-out includes the core removal work, containment, and clean-down. We confirm the scope before we start so there are no surprises. Additional work such as timber treatment or replacement insulation is quoted separately if you need it.
✓
Full foam removal
We remove open cell spray foam, closed cell spray foam, and polyurethane foam from lofts, roofs, cavities, and commercial units using the method that suits the material and substrate. No foam is left behind.
✓
Dust and fume containment
Protective sheeting, a negative air machine, and an air scrubber keep dust and chemical particles out of your living space. We run HEPA filtration throughout and vacuum every surface before we leave.
✓
Moisture and timber check
We use a thermal imaging camera and moisture meter to check for hidden damp and rot behind the foam. If we find wet timbers, we tell you what needs drying or treating before any new insulation goes in.
✓
Waste removal and disposal
All removed foam goes into sealed disposal bags and leaves site the same day. We dispose of it responsibly and can provide waste transfer documentation for commercial jobs or lender requirements.
✓
Written removal summary
You get a short report covering what was removed, the condition of the roof structure, and any ventilation or insulation recommendations. This is often what lenders and surveyors ask to see after a spray foam rejection.
How it works
How our same day removal process works
01
Call and triage
You ring 02080885342 and speak to someone who knows spray foam, not a call centre. We ask what type of foam you have, where it is, and why it needs to come out. Within minutes we give you a realistic arrival window, usually the same day, and confirm the price range before we set off.
02
Site assessment
On arrival we inspect the loft, roof, cavity, or unit and check the foam type, thickness, and coverage. A thermal imaging camera helps us spot hidden damp and rot behind the insulation. We agree the scope with you, lay protective sheeting, and set up the negative air machine before any removal starts.
03
Controlled removal
Depending on the foam and substrate, we use dry ice blasting machine equipment, sand blasting equipment, or hand tools such as a reciprocating saw and oscillating multi-tool. Open cell spray foam usually comes away quickly; closed cell spray foam takes longer because it bonds harder. Most domestic lofts take four to eight hours.
04
Clean-down and check
Every surface is vacuumed with a HEPA-filtered industrial vacuum and wiped down. We check timber moisture readings again, confirm the roof ventilation path is clear, and walk you through the space so you can see the foam is gone. Waste leaves site in sealed disposal bags the same day.
05
Report and next steps
You get a short written summary of what was removed, the condition of the timbers, and any ventilation or insulation recommendations. If a lender or surveyor needs confirmation, we can provide the details they ask for. We can also quote for replacement insulation that meets Building Regulations Part L and PAS 2035.
Tools & methods
Tools and methods we use for removal
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Dry ice blasting machine
Freezes and lifts closed cell spray foam from timber and masonry without leaving secondary media behind. Ideal for fragile or historic roof structures.
Sand blasting equipment
Strips stubborn foam from hard surfaces such as brick, stone, and concrete. We contain and recover the media for safe disposal.
Thermal imaging camera
Reveals hidden damp, rot, and cold spots behind the foam so we can show you exactly what is going on before and after removal.
Industrial vacuum with HEPA filters
Captures fine dust and foam particles during and after removal. We vacuum every surface before we leave so the space is clean enough to use.
Negative air machine and air scrubber
Keeps dust and chemical particles out of your living areas by maintaining negative pressure in the work zone throughout the job.
Reciprocating saw and oscillating multi-tool
Cuts away foam around timbers, pipes, and cables where blasting is too aggressive. Bosch and Makita cordless tools let us work in tight loft spaces.
3M respirators and protective clothing
Protects our technicians from spray foam chemical hazards and airborne particles. We also provide masks for you if you need to be in the property.
Real results
Before and after.
Westminster loft cleared for lender
Before
A two-bedroom flat in Westminster had closed cell spray foam across the entire roof slope. The buyer's lender refused to proceed until it was removed. The loft hatch was small, and the timbers were showing early signs of damp.
After
We removed all the foam in a single day using dry ice blasting, vacuumed the space with HEPA filtration, and took moisture readings. The timbers were dry enough for the lender's surveyor to inspect. The sale completed three weeks later.
Croydon bungalow damp resolved
Before
A bungalow in Croydon had open cell foam sprayed between the rafters. The owner noticed a musty smell and damp patches on the ceiling. Moisture readings showed the foam was trapping water against the timbers.
After
We stripped the foam in five hours, dried the timbers, and treated two areas of early rot. The ceiling patches were left to dry out and redecorated. The musty smell cleared within a week.
Islington terrace prepared for sale
Before
A Victorian terrace in Islington had spray foam installed years ago. The surveyor would not value the property because the timbers were hidden. The owner needed a quick resolution to keep the chain together.
After
We removed the foam the same day, provided a written summary and photographs, and confirmed the roof structure was sound. The surveyor re-inspected within a week and the valuation was issued without a deduction for the foam.
Problems we solve
Spray foam problems we solve across London
Spray foam causes more problems than most homeowners realise. Here are the issues we are called out to fix most often, and what happens if they are left alone.
Ask a pro →↗
Reduced property value
Same day removal restores the roof space to a clean, inspectable condition. Once the foam is gone and the timbers are checked, valuers can assess the property on its actual merits rather than the insulation problem.
Hidden damp and rot
We remove the foam, expose the timbers, and take moisture readings with a thermal imaging camera. If rot is found, we advise on treatment and drying before any replacement insulation is fitted.
Roof ventilation issues
Once the foam is out, we check the ventilation path and tell you what needs opening up. We can also quote for compliant replacement insulation that meets Building Regulations Part L without blocking airflow.
