Winchester
Spray foam, loft insulation and damp in Winchester homes
Winchester was the ancient capital of Wessex, and its cathedral, college and medieval streets make it one of the most historic cities in England. Much of the centre is a conservation area with a very large number of listed buildings, from timber-framed houses to Georgian brick fronts. The River Itchen runs through the city and its water meadows.
Older Winchester buildings are a mix of brick, flint and timber framing on chalk, often with lime mortar and clay tile roofs. They were built to breathe. Damp problems usually start when that is blocked, by cement render, hard pointing, modern paints or raised ground outside. We use breathable materials and trace the cause before suggesting any work.
Outside the centre, Hyde and Fulflood are full of Victorian terraces and villas, St Cross has older cottages and larger homes, and Stanmore was built as a council estate from the 1920s. Weeke, Harestock, Badger Farm and Oliver's Battery are mainly post-war and later. In these homes the main job is topping up loft insulation and fitting raised boarding.
Spray foam is a particular worry in old roofs. It sticks to rafters and battens, hides their condition and can trap moisture in timbers that need air. Many lenders and surveyors are cautious about spray foam. We remove it by hand, clean the timbers back and, where you want insulation, lay Knauf mineral wool to 300mm with ventilation kept clear.

Questions we get in Winchester
Do you cover all of Winchester?
Yes. We cover Winchester across SO22 and SO23, from the city centre, Hyde, Fulflood and St Cross to Stanmore, Weeke, Harestock, Badger Farm and Oliver's Battery. Surveys for spray foam removal and loft insulation are free, and you get a written price before any work is agreed.
Can you insulate the loft of a listed house in Winchester?
Often, yes. Loft insulation happens inside the roof and does not change how the house looks. Listed homes may still need listed building consent, so check with Winchester City Council first. We use breathable mineral wool that suits old timbers, and flag anything we spot at the survey.
Why do old Winchester houses get damp?
Brick, flint and lime walls were built to let moisture escape. Cement render, hard pointing and plastic paints can trap it, and raised paths or beds can bridge the base of the wall. We trace the true cause first and use breathable materials where the building needs them.
Is spray foam bad for an old Winchester roof?
It can be. Old roof timbers need airflow, and foam stuck to them can trap moisture and hide rot. 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, photos and a 10-year guarantee.
How much loft insulation should my Winchester home have?
Current guidance is around 270mm. Many Victorian and post-war homes in the city have far less, or insulation squashed by storage. We lay Knauf mineral wool to 300mm and keep the eaves clear for ventilation, with raised boarding if you want to keep using the loft.
What happens at a free survey in Winchester?
We look at the loft, the roof timbers, any spray foam and any damp walls, take photos and explain what we find in plain English. Then you get a written price, with no obligation. If nothing needs doing, we will tell you. Spray foam and loft surveys are free.
