Spray foam, loft insulation and damp in Wiltshire homes
Wiltshire's housing splits between old market towns and fast growing newer areas. Swindon grew around the Great Western Railway works, and its Railway Village of Victorian stone cottages still stands, surrounded by brick terraces and large post-war and modern estates. Salisbury is a medieval cathedral city with timber framed, brick and flint buildings, and much of its centre is a conservation area.
In the north and west of the county the stone changes. Chippenham, Corsham and Bradford on Avon are built largely of Bath stone, and Trowbridge, the county town, grew on the wool trade with stone cloth mills and weavers' houses. Out on the chalk downland, villages mix flint, brick and chalk cob, often under thatch. The post-war and modern estates around every town are where a loft insulation top up and raised boarding make the quickest difference.
Rivers shape the damp problems we see. Salisbury sits where several rivers meet, including the Avon, and low lying parts of the city are prone to flooding and high water tables. Chippenham is on the Avon too. Old stone, flint and cob walls need to breathe, so cement render, hard pointing and raised ground levels trap moisture. Chalk and cob walls are easily damaged by the wrong repair. We trace the cause first, and damp proofing carries a 25 year insurance backed guarantee.
Spray foam has been sold across Wiltshire as a fix for cold, draughty roofs, but it hides the timbers and can trap moisture against them, and under thatch or old tiles that matters. Many lenders and surveyors are cautious about spray foam, so it often comes up when people sell or remortgage. We remove it by hand, clean the timbers back and issue a Certificate of Removal with a 10 year guarantee. For lofts we lay Knauf mineral wool to 300mm.

Why do old houses in Salisbury get damp?
Parts of Salisbury sit on low ground where rivers meet, so water tables are high and walls dry slowly. Old brick, flint and timber framed buildings need to breathe, and cement render or raised ground levels trap moisture. We find the real cause first, then fix it properly.
Can you work on chalk cob or flint walls in Wiltshire?
Yes, with care. Chalk cob and flint walls need to stay dry at the base and breathe, so we never seal them with cement or plastic. If we find damp we look at render, gutters and ground levels first. In the loft we use breathable mineral wool and keep ventilation clear.
How much loft insulation should a Swindon home have?
Current guidance is around 270mm of mineral wool. Many Swindon terraces and post-war estates have far less, or insulation squashed flat by boards. We clear old material where needed, lay Knauf mineral wool to 300mm with a 10 year guarantee, and fit raised boarding so you keep your storage space.
Is spray foam a problem in my Wiltshire home?
It can be. Foam stuck to the underside of a roof hides the timbers and can trap moisture against them. Many lenders and surveyors are cautious about spray foam. We remove it by hand, clean the timbers back and give you a Certificate of Removal and a 10 year guarantee for your surveyor.
