Surrey
Spray foam, loft insulation and damp in Surrey homes
Surrey is a county of bands. The chalk of the North Downs runs east to west across the middle, from Farnham through Guildford, Dorking and Reigate. South of it, the Lower Greensand hills rise to Leith Hill before dropping to the Weald clay. To the north lies London Clay, and in the north west, around Camberley and Woking, the sandy heaths of the Bagshot beds.
Building materials follow the ground. Older houses use Bargate stone around Godalming and Guildford, soft Reigate stone along the Downs, flint in chalk country and red brick and clay tile hanging almost everywhere. Historic centres in Guildford, Farnham, Dorking and Reigate are conservation areas with many listed buildings, and soft stone, brick and lime need breathable repairs.
Most Surrey homes, though, are railway era or later. Woking and Redhill grew after their lines opened in the mid 1800s, and the 1930s filled Ewell, Stoneleigh, Hinchley Wood and much of the north of the county with semis. Post-war estates such as Merstham, Sheerwater and the Old Dean followed. These are the homes where a loft top-up to 300mm with Knauf mineral wool helps most.
Rivers are the county's damp risk. The Thames, Wey and Mole have all flooded homes in wet winters, notably in Staines and around the Wey in 2014, and clay soils hold water against walls. We diagnose before we treat. Spray foam turns up across Surrey too, and many lenders and surveyors are cautious about spray foam. We remove it and issue a Certificate of Removal.

Questions we get in Surrey
Do you cover all of Surrey?
Yes. We cover Surrey from our Sevenoaks office in Kent, including Guildford, Woking, Camberley, Farnham, Epsom, Esher, Leatherhead, Dorking, Reigate, Redhill and Staines, plus the villages between them. Surveys for loft insulation and spray foam removal are free, and you always get a written price first.
Why do old Surrey houses need breathable damp repairs?
Many older Surrey buildings are built from soft stone, flint or brick laid in lime mortar. These walls move moisture in and out, and cement render or hard pointing can trap it inside. We find the source first and choose fixes that suit the wall. Damp proofing carries a 25-year insurance-backed guarantee.
Is flooding behind damp in Surrey homes near rivers?
Sometimes. The Thames, Wey and Mole have all flooded homes in wet winters, and walls take months to dry. But plenty of riverside damp comes from gutters, raised ground or blocked air bricks. We check what is really going on before recommending any treatment.
Is spray foam a problem when selling in Surrey?
It can be. Many lenders and surveyors are cautious about spray foam because it hides the roof timbers and can trap moisture. It often comes up at the mortgage survey. We remove it by hand, clean the timbers and provide a Certificate of Removal and a 10-year guarantee.
How much loft insulation should a Surrey semi have?
Current guidance is around 270mm. Many 1930s and post-war semis across Surrey still have thin original insulation or wool crushed under boards. We lay Knauf mineral wool to 300mm and fit raised boarding for storage. Insulation is covered by a 10-year guarantee.
