St Albans
Spray foam, loft insulation and damp in St Albans homes
St Albans grew up beside the Roman town of Verulamium, and its cathedral sits at the top of a medieval centre. Fishpool Street, St Peter's Street and Holywell Hill hold timber-framed houses, many behind Georgian brick fronts, and much of the old city is a conservation area with a large number of listed buildings. These homes need breathable materials, not modern sealants.
The railway brought rapid growth in the late 19th century. Clarence Park, Fleetville, Bernards Heath and the streets around the station filled with Victorian and Edwardian terraces and villas, mostly solid brick with slate roofs. Many have since had loft conversions. Marshalswick, Jersey Farm and the estates to the north and east followed in the interwar and post-war years.
House prices here mean buyers' surveyors look hard at lofts. Spray foam sprayed under the roof of a Victorian terrace, or into the slopes of a converted loft, often surfaces during a sale. Many lenders and surveyors are cautious about spray foam, so we remove it by hand, clean the timbers back and give you photos and paperwork to pass on.
Damp in St Albans tends to follow the building type. Solid-walled terraces get damp where cement render, raised paths or blocked gutters trap water, and older cellars stay cool and damp. In the post-war homes of Marshalswick and Jersey Farm the job is more often a loft insulation top-up to 300mm of Knauf mineral wool, with raised boarding for storage.

Questions we get in St Albans
Which parts of St Albans do you cover?
All of it. We cover the city centre, Fleetville, Clarence Park, Bernards Heath, Sopwell, Marshalswick and Jersey Farm across AL1, AL3 and AL4, plus Harpenden and Hatfield nearby. Surveys for spray foam removal and loft insulation are free, and you get a written price before any work is agreed.
Why does spray foam come up when selling in St Albans?
Buyers' surveyors check lofts closely, and foam covering the roof timbers stops them seeing the condition of the wood. 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.
Can you remove spray foam from a loft conversion?
Often, yes. Foam in the sloping ceilings of a converted loft is harder to reach, so we look at access at the survey and explain exactly what is involved. After removal, the timbers are left clean and visible so a surveyor can check them, and the roof can be insulated properly.
Why are Victorian terraces in St Albans damp?
They have solid brick walls with no cavity, built to breathe. Cement render, modern pointing, raised paths and blocked gutters can trap water in them. We trace the actual cause before recommending damp proofing, and where treatment is needed it carries a 25-year insurance-backed guarantee.
Can you insulate a listed home in St Albans?
Often, yes. Loft insulation goes inside the roof and does not change how the house looks, but listed homes may need consent, so check with St Albans City and District Council first. We use breathable mineral wool that suits old timber and brick.
How much loft insulation should my home have?
Current guidance is around 270mm. Many interwar and post-war homes in Marshalswick and Jersey Farm have far less, often squashed flat. We lay Knauf mineral wool to 300mm with a 10-year guarantee, and fit raised boarding so you keep your storage space.
