Dorking
Spray foam, loft insulation and damp in Dorking homes
Dorking sits where the River Mole cuts through the North Downs, with Box Hill on one side and Ranmore on the other. The old town centre along the High Street, West Street and South Street is a conservation area, full of Georgian and Victorian frontages, timber framed buildings behind them and the sandstone caves dug under South Street.
The ground changes across the town. Chalk rises to the north, while the Lower Greensand runs south towards Leith Hill, and older cottages here use local stone, flint, brick and clay tile hanging. Solid walls like these need to breathe, so we are careful with what goes on them and what gets used to fix damp.
Water is the main local issue. The Pipp Brook runs through the middle of town and has a history of flooding nearby streets, and homes close to the Mole can suffer after wet winters. Many damp problems we see in Dorking start outside: blocked gutters, raised paths and gardens against old walls, or leaks around chimneys. We trace the cause before suggesting any treatment.
Beyond the centre, Dorking has Victorian terraces near the stations, interwar and post-war semis, and council built estates such as Goodwyns and Chart Downs. Those lofts are usually quick wins for a top-up to 300mm with Knauf mineral wool and raised boarding. Spray foam crops up too, and many lenders and surveyors are cautious about spray foam. We remove it and issue a Certificate of Removal.

Questions we get in Dorking
Do you cover Dorking and the villages around it?
Yes. We cover RH4 and RH5 from our Sevenoaks office, including Dorking town, Westcott, Pixham, Brockham, Holmwood, Capel, Ockley and Mickleham. Surveys for loft insulation and spray foam removal are free, and you get a written price before anything is agreed.
My cottage near the Pipp Brook is damp. What can you do?
First we find out where the water comes from. Homes near the brook can suffer after floods, but damp also comes from gutters, ground levels and leaks. Walls need time to dry before treatment. When damp proofing is right, it carries a 25-year insurance-backed guarantee.
Can you work on stone and flint walls in Dorking?
Yes. Old stone, flint and soft brick walls need to breathe, and sealing them with cement or the wrong plaster often makes damp worse. We use breathable approaches where they suit the wall, and we will tell you honestly when the fix is outside, not inside.
Is my house in the Dorking conservation area a problem for insulation?
Usually not. Loft insulation goes inside the roof and does not change how the house looks. Listed buildings may need consent, so check with Mole Valley District Council if yours is listed. We use breathable Knauf mineral wool, laid to 300mm, which suits older timbers.
Why remove spray foam from a Dorking loft?
Many lenders and surveyors are cautious about spray foam because it covers the roof timbers and can trap moisture. It often comes up at the mortgage survey. We remove it by hand, clean the timbers back and give you a Certificate of Removal and a 10-year guarantee.
How do I book a survey?
Call 0800 870 8086 or fill in the form on this page. We arrange a time that suits you, check the loft and any problem walls, take photos and explain what we find. You then get a written price. Loft and spray foam surveys are free; ask about damp surveys when you book.
