Bath’s Georgian and Victorian terraces, particularly around The Circus, Walcot and nearby streets, were built with breathable stone and lath construction that relies on natural airflow. When closed-cell spray foam was added to lofts in the last twenty years, it often sealed in damp from the valley gutters and stone walls that are common in the area. Homeowners now call for removal because the foam has started to hold condensation against rafters and ceilings, causing timber staining and musty smells that worsen after heavy winter rain.
Removal work here differs from modern estates because the roof structures are irregular, with varying pitch angles and multiple layers of historic insulation already present. Technicians must cut the foam in controlled sections to avoid disturbing original lathe and plaster ceilings below, then extract it through the loft hatch or temporary roof access points. Once the foam is gone, the original ventilation paths around eaves and ridge tiles need to be reopened so the stone walls can dry naturally again.
After extraction, the team checks for hidden rot in the rafters and checks that the lead flashings and stone parapets are still sound. In Bath’s damp winters, any remaining moisture pockets can lead to mould returning within months if the loft is not left properly ventilated. The address at Compass Court, 74 Circus Mews, BA1 2PW serves as the base for jobs across the city and immediate surrounds, with crews on call 24/7 when homeowners discover problems during roof leaks or energy surveys.
Technician insight
In Bath, the thing that catches most people out with loft spray foam removal is how quickly the closed-cell foam bonds to the irregular stone and timber in Georgian terraces around The Circus and Walcot, hiding rot that only appears once you start cutting sections away.
Walcot Terrace Loft
Homeowner noticed musty smell and ceiling stains after heavy rain. Inspection found closed-cell foam sealing moisture against original rafters. Crew removed the foam in sections, reopened eaves vents and left the loft clear for natural drying.
How it works
- 1
Initial Loft Inspection
Assess foam depth, roof structure condition and any signs of trapped moisture in properties across Bath and surrounds.
- 2
Containment Setup
Seal the loft space to prevent foam particles from entering living areas below during cutting and extraction.
- 3
Foam Cutting and Removal
Section the closed-cell foam and remove it through the hatch or temporary access while protecting original timber and stone.
- 4
Ventilation Restoration
Reopen eaves, ridge and any blocked air paths so the historic roof can breathe again after the foam is gone.
Pricing
Cost depends on loft size, foam thickness and access difficulty in older Bath properties.
