Hemel Hempstead
Spray foam, loft insulation and damp in Hemel Hempstead homes
Hemel Hempstead is two towns in one. The Old Town round the High Street and St Mary's Church is centuries old, with timber-framed, brick and flint buildings, many of them listed, inside a conservation area. Almost everything else was built after Hemel was named a New Town in 1947, in planned neighbourhoods each with its own shops and school.
Adeyfield came first, followed by Bennetts End, Chaulden, Warners End, Gadebridge, Highfield and Grovehill, with Woodhall Farm added later. That means a huge number of homes from the 1950s, 60s and 70s, many of them former council houses now privately owned. They were built with very little loft insulation by today's standards, and much of what is there has been squashed flat over the decades.
For those homes the most useful job is usually simple: clear out the old, thin layer where needed, lay Knauf mineral wool to 300mm and fit raised boarding so you keep the loft for storage. In terraces we check the party walls in the loft too, as gaps there let heat and draughts through to next door.
The Old Town and the valley floor are a different story. The Gade and the Bulbourne run through Hemel, and the Grand Union Canal follows the Bulbourne valley, so lower ground can be damp. Old flint and brick walls need to breathe, and cement render or raised paths often cause the damp we are called out to. Where spray foam has been added to a roof, many lenders and surveyors are cautious about it, so we remove it by hand.

Questions we get in Hemel Hempstead
Which parts of Hemel Hempstead do you cover?
All of it. We cover the Old Town, Adeyfield, Bennetts End, Chaulden, Warners End, Gadebridge, Highfield, Grovehill, Woodhall Farm and Leverstock Green across HP1 to HP3, plus Berkhamsted and St Albans. Surveys for spray foam removal and loft insulation are free, and you get a written price.
Do New Town houses in Hemel need more loft insulation?
Usually, yes. Homes built in the 1950s to the 1970s had far less than today's guidance of around 270mm, and it has often been squashed by storage. We lay Knauf mineral wool to 300mm with a 10-year guarantee and can fit raised boarding over the top.
Can I board my loft without losing insulation?
Yes. Boards laid straight onto insulation crush it and stop it working. We fit raised loft boarding that sits above the full 300mm depth, so you get a safe storage floor and keep the warmth. Add it at your free survey and it goes on the written price.
Why are older homes in Hemel Old Town damp?
Many have flint, brick or timber-framed walls built to breathe. Cement render, modern pointing and raised paths can trap water in them, and lower ground near the Gade holds moisture. We trace the real cause before suggesting any work, and use breathable repairs that suit old walls.
Is spray foam a problem when selling in Hemel Hempstead?
It can be. Many lenders and surveyors are cautious about spray foam because it covers the roof timbers and can trap moisture. We remove it by hand, clean the timbers back and give you photos, a Certificate of Removal and a 10-year guarantee for the buyer's surveyor.
What happens at a free survey in Hemel Hempstead?
We check the loft, the roof timbers, any spray foam and any damp you are worried about, take photos and explain what we find in plain English. Then you get a written price, with no pressure. If nothing needs doing, we will tell you. Loft and spray foam surveys are free.
