Bath
Spray foam, loft insulation and damp in Bath homes
Bath is a World Heritage city built largely from honey-coloured Bath stone, a soft oolitic limestone. The Georgian crescents and terraces of the centre, Lansdown, Bathwick and the Royal Crescent area sit alongside Victorian villas and terraces in Widcombe, Larkhall, Oldfield Park and Lower Weston. Much of the city is a conservation area and a large number of homes are listed.
That matters for lofts and damp. Bath stone and lime mortar work by letting moisture in and out. Cement pointing, plastic paints and spray foam stop that happening, so water gets trapped in walls, roof timbers and wall plates. Foam sprayed onto the underside of old slates and stone tiles hides leaks and holds moisture against rafters that are often well over a century old.
Removal in a Bath period home is careful hand work. We take the foam off without damaging battens and rafters, clean the timbers back, check them for rot or beetle, and photograph everything for your records and your surveyor. Then we fit breathable insulation between and over the joists, with raised boarding where you want storage, keeping ventilation paths clear.
Twentieth century Bath is simpler. Odd Down, Southdown, Twerton, Whiteway and Combe Down have interwar and postwar semis and terraces with easy lofts that just need a proper top-up to 270mm to 300mm. Damp there is more often condensation, failed gutters or ground levels sitting too high against the wall.

Questions we get in Bath
Do you cover all of Bath?
Yes. We cover the whole city, including Lansdown, Bathwick, Widcombe, Larkhall, Oldfield Park, Weston, Combe Down and Odd Down, plus nearby places like Keynsham and Bradford on Avon. Surveys are free and you get a written price before anything starts, so there are no surprises.
Is spray foam bad for Bath stone houses?
It is a poor match. Bath stone and lime mortar need to breathe, and foam sprayed under slates or stone tiles seals moisture against old rafters and battens. It also hides the roof, so leaks and rot go unseen. Many lenders and surveyors are cautious about spray foam, especially on older properties like these.
My Bath home is listed. Can you still help?
Yes. We remove foam by hand, protect original timbers and use breathable insulation suited to historic buildings. Listed homes may need listed building consent for some changes, so check with Bath and North East Somerset Council before work starts. We can give you a written description of the proposed work to help with that conversation.
Why do old Bath houses get damp?
Usually because the stone cannot dry out. Cement pointing, cement render, masonry paint, blocked gutters and raised ground levels are common causes. We trace the source first and fix that, often outside, rather than injecting chemicals into walls that never had a damp course designed in the modern sense.
Can I sell a house in Bath with spray foam in the loft?
You can, but many lenders and surveyors are cautious about spray foam, so it often slows a sale or knocks the price. We remove it by hand, clean the timbers back and give you before and after photos plus paperwork your buyer's surveyor can check. Get it booked before you list.
Can you board a loft without squashing the insulation?
Yes. We fit raised boarding on legs, so you get storage above while the 270mm to 300mm of mineral wool underneath stays at full depth and keeps working. In older Bath roofs we also keep the eaves and ventilation clear, which helps stop condensation building up in the loft.
