Exactly what happens from your first phone call to your completion certificate — the same proven process we've used on hundreds of properties across the UK.
Step 1: The Free Survey & Assessment
Every project starts with a free, no-obligation survey of your loft or roof space. Our surveyor identifies the type of foam (open-cell or closed-cell), how it was applied, whether it sits directly on tiles or felt, and any signs of trapped moisture or timber damage. This assessment follows RICS surveyor standards, because we know lenders will scrutinise it later.
Step 2: Detailed Written Quote
You receive a clear, itemised written quotation — no hidden costs, no surprise charges. It sets out the scope of removal, any repairs needed, replacement insulation options, and the full timeline. Most residential jobs take one to three days, and we tell you exactly which before you commit.
Step 3: Specialist Foam Removal
On the agreed dates, our full-time team arrives with specialist removal equipment. Open-cell foam is extracted with industrial machinery; closed-cell foam bonded directly to tiles or felt requires careful manual techniques to avoid damaging the roof structure. The worksite is sheeted and sealed, and we clean up behind ourselves every day.
Step 4: Timber Inspection & Remediation
With the foam removed, we inspect the rafters and felt the foam was hiding. This is where many problems are uncovered — moisture damage, early rot, degraded felt, cracked rafters. Affected timbers are treated and stabilised, failed felt is replaced, and cracked rafters are repaired with sister joists where needed. Nothing is left hidden.
Step 5: Replacement Insulation
We install breathable, lender-accepted replacement insulation — typically multifoil products such as Superfoil — bringing the loft up to modern thermal standards without the risks that made spray foam a mortgage problem in the first place.
Step 6: Completion Certificate & Aftercare
You receive a written completion certificate and full warranty documentation, accepted by buyers' lenders and solicitors. Many of our customers are able to remortgage or complete their sale within weeks of the work being finished. If anything needs attention afterwards, our team is a phone call away.

Why the Process Matters
Spray foam removal done badly leaves hidden damage, failed insulation, and a property that still fails its mortgage survey. Done properly — as outlined above — it leaves your roof sound, your loft compliant, and your sale or remortgage free to proceed. That difference is why the process, the people, and the paperwork matter as much as the price.
