Hertford
Spray foam, loft insulation and damp in Hertford homes
Hertford is an old market town with Saxon roots, a castle and a medieval street plan that still shapes the centre. Fore Street, Maidenhead Street and the lanes off them are lined with timber-framed buildings, many hidden behind later brick or render fronts, and a large part of the town is a conservation area with a high number of listed buildings.
Four rivers meet here: the Lea, the Beane, the Mimram and the Rib. Hartham Common and the meadows along them are flood plain, and homes on the lower ground can see damp in walls and floors after a wet winter. Before recommending any damp proofing we check ground levels, drainage and whether the damp course has been bridged by paths or patios.
Timber-framed and solid brick houses were built to let moisture escape. Modern cement render, gypsum plaster and plastic paints trap it, and spray foam on the underside of an old roof can do the same to the rafters. Many lenders and surveyors are cautious about spray foam, and on an old frame it can hide rot. We remove it by hand and use breathable mineral wool instead.
Away from the centre, Bengeo has Victorian and Edwardian terraces and villas on the hill north of the river, while Sele Farm, the Hertingfordbury Road area and estates to the south and west are largely post-war. Those homes often have thin, squashed loft insulation. A top-up to 300mm of Knauf mineral wool with raised boarding is usually the job that makes most difference.

Questions we get in Hertford
Do you cover all of Hertford?
Yes. We cover Hertford across SG13 and SG14, from the town centre out to Bengeo, Sele Farm and Hertingfordbury, plus Ware and Welwyn Garden City nearby. Surveys for spray foam removal and loft insulation are free, and you get a written price before any work is agreed.
Why do homes near Hartham Common get damp?
Hertford sits where four rivers meet, and the land along them is flood plain with a high water table. Walls and floors on low ground can stay wet after a wet winter, especially where paths bridge the damp course. We find the real cause before recommending any damp proofing.
Can you work on a timber-framed house in Hertford?
Yes. Old frames need to breathe, so we avoid anything that traps moisture. We use breathable mineral wool in the loft and look for causes like cement render or raised ground outside before suggesting damp work. Listed homes may need consent, so check with East Herts Council first.
Is spray foam bad for an old Hertford roof?
It can be. Foam stuck to old rafters hides the timbers, so rot or beetle can go unseen, and it can trap moisture. 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.
How much loft insulation should my Hertford home have?
Current guidance is around 270mm. Many post-war homes in Sele Farm and nearby estates have far less, often squashed under boxes. We lay Knauf mineral wool to 300mm, backed by a 10-year guarantee, and fit raised boarding so you keep your storage space.
What guarantee comes with damp proofing in Hertford?
Damp proofing comes with a 25-year insurance-backed guarantee. Loft insulation has a 10-year guarantee, and spray foam removal comes with a Certificate of Removal and a 10-year guarantee. Everything is listed on your written price, so you know exactly what you are getting before you agree.
