Guildford
Spray foam, loft insulation and damp in Guildford homes
Guildford is an old market town built on the slopes either side of the River Wey. The cobbled High Street, the castle and the streets around them sit in a conservation area, and many buildings there are listed. Older houses in and around the town use red brick, clay tile hanging and Bargate stone, the brown sandstone quarried near Godalming.
Step out of the centre and the stock changes quickly. Charlotteville and Stoke have tight Victorian and Edwardian terraces with small, low lofts. Onslow Village was laid out as a garden suburb in the 1920s. Merrow and Burpham are mostly interwar and post-war semis, and Park Barn and Bellfields are largely post-war estates. Each era has its own loft layout, and we plan the job around it.
The Wey is the big local factor for damp. Low streets near the river and the town centre have flooded in wet winters, and older solid brick walls close to the water can draw moisture up. We find the real source before suggesting anything, because a lot of damp in older Guildford homes is from blocked gutters, high ground or bridged damp courses, not rising damp.
Guildford also has a large rental market around the University of Surrey, and spray foam turns up in rented and recently bought homes alike. Many lenders and surveyors are cautious about spray foam, so it often surfaces at the survey stage of a sale. We remove it by hand, clean the timbers and hand you a Certificate of Removal. New insulation is Knauf mineral wool to 300mm.

Questions we get in Guildford
Do you cover all of Guildford?
Yes. We cover Guildford across GU1 to GU4 from our Sevenoaks office, including Charlotteville, Stoke, Onslow Village, Merrow, Burpham, Park Barn and the villages around the town. Surveys for loft insulation and spray foam removal are free, and you always get a written price before anything is agreed.
Can you insulate a loft in a listed Guildford house?
Often, yes. Loft insulation sits inside the roof and does not change how the house looks. Listed buildings may still need consent, so speak to Guildford Borough Council first. We use breathable Knauf mineral wool that suits old timbers, and we flag anything that needs care at the survey.
My Guildford home is near the Wey. Is my damp from flooding?
Not always. Homes near the river can suffer after wet winters, but much of the damp we see in older Guildford houses comes from gutters, high ground outside or bridged damp courses. We trace the source before quoting. Damp proofing work comes with a 25-year insurance-backed guarantee.
I rent out a house near the university. Can you remove spray foam?
Yes. Spray foam is common in rented homes and many lenders and surveyors are cautious about spray foam, which matters if you sell or refinance. We remove it by hand, clean the timbers and give you a Certificate of Removal and a 10-year guarantee. We can work around tenants with notice.
How deep should loft insulation be in a Guildford semi?
Current guidance is around 270mm. Many interwar and post-war lofts in Merrow, Burpham and Park Barn have far less, or old wool squashed flat under stored boxes. We top up with Knauf mineral wool to 300mm and can fit raised boarding so you keep your storage.
What happens at a free survey?
We look at the loft, 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 pressure. If nothing needs doing, we tell you. Loft and spray foam surveys are free; ask us about damp surveys.
