Truro
Spray foam, loft insulation and damp in Truro homes
Truro is Cornwall's only city, and its housing spans three centuries in a small space. The centre has Georgian townhouses on Lemon Street and around Walsingham Place, with Victorian terraces from the city's 19th century growth climbing the valley sides. Out towards Highertown, Kenwyn and Threemilestone there are post-war semis, bungalows and newer estates, while the villages around the Fal are full of older stone and cob cottages.
Cornish building materials shape what we do here. Older homes are often built of local stone or granite under slate roofs, with solid walls and no cavity. These houses need to breathe. Seal them up with the wrong materials and moisture gets trapped in the walls and roof timbers. That is why we use breathable mineral wool in older lofts rather than anything that locks damp in.
Truro sits low in a valley where the Kenwyn and Allen rivers meet at the head of the Truro River, and Cornwall's mild, wet Atlantic climate brings plenty of rain and humid air. Damp is a common worry in older properties, from condensation in poorly ventilated lofts to penetrating damp through solid stone walls and cement render. We trace the cause before recommending anything.
The city centre is a conservation area with many listed buildings, so careful, breathable work is the rule. Spray foam is a particular risk under slate on solid stone homes, where it can trap moisture against battens and rafters. Many lenders and surveyors are cautious about spray foam. We remove it by hand, clean the timbers back and leave you with photos and paperwork for your surveyor.

Surveys for spray foam removal and loft insulation are free, and you get a written price before any work is agreed. Call 0800 870 8086 to book.
Can you insulate a Cornish granite or stone cottage?
Yes, with the right materials. Solid granite and stone walls have no cavity and need to breathe. We use breathable mineral wool in the loft and keep the eaves ventilated. Sealing an old Cornish cottage with foam or plastic sheeting can trap moisture and cause exactly the damp you were trying to avoid.
Is spray foam under a Cornish slate roof a problem?
It can be. Foam stuck to the underside of slate can hold moisture against battens and rafters and hide rot from view. Many lenders and surveyors are cautious about spray foam, so it often surfaces when you sell or remortgage. We remove it by hand, clean the timbers back and give you photos and paperwork for your surveyor.
Why is damp so common in older Truro homes?
Cornwall's mild, wet climate brings a lot of rain and humid air, and many older Truro homes have solid stone walls with no cavity. Blocked gutters, failing pointing, cement render on stone and poor loft ventilation all trap moisture. We find the actual cause first, then fix the outside as well as the inside.
My Truro home is listed or in the conservation area. Can you still help?
Usually, yes. Loft insulation and spray foam removal happen inside the roof and do not change how the house looks. If your home is listed, some work may need listed building consent, so check with Cornwall Council's planning team first. We use breathable materials that suit older buildings and flag anything we spot at the survey.
What happens at a free survey in Truro?
