Hersham's homes
The character of Hersham roofs
Hersham is a good illustration of how Surrey was built. The stock here runs to interwar and post-war detached and semi-detached homes, older village cores and a good deal of recent development, and the roofs are predominantly generous pitched roofs, frequently with modern trussed construction on the newer stock. Within a single street you can find a loft you can stand up and walk around in, and one three doors along where the only sensible approach is to work on your knees.
That variation is exactly why we survey before quoting. Two lofts of identical floor area can differ by a substantial margin in price because one has 150mm joists and a wide hatch, and the other has shallow, irregular timbers, a 400mm opening and a cold water tank sitting in the middle of the run.
Locally, modern trussed roofs have dense timber webbing that makes movement awkward, so boarding needs planning around the truss layout — worth knowing before you compare quotes.

Five ways we keep Hersham homes warm
Every one of these begins with the same free survey and ends with a fixed price agreed before anything starts.
Loft insulation installation
270mm depthMineral wool cross-laid to the 270mm depth current regulations recommend. For most Hersham homes this is the single highest-value thing you can do to the building.
Loft boarding
Storage-readyStorage that does not flatten your insulation. We raise the deck on battens so the full depth survives underneath — the version most Hersham lofts should have had first time.
Loft ladders
Fitted in a dayThe thing that turns a loft you avoid into one you use. Grab rails and a boarded landing area where the design allows.
Loft makeovers
All-in-oneThe whole loft dealt with at once, for one fixed price. Most Hersham properties are finished within a day.

Questions & answers
Hersham loft insulation — common questions
How much does loft insulation cost in Hersham?
We price Hersham jobs after a free survey, itemised so you can see what the insulation, any boarding and any removal each cost. There is no call-out charge and the figure does not move once it is written. The London cost guide explains what drives it.
How long does the work take in a typical Hersham home?
A straightforward insulation job in a three-bedroom Hersham property is a half-day. Larger, cluttered or awkward-access lofts take longer, and stripping out failed material adds time — all of which is established at survey and reflected in the quote.
Do I need planning permission in Hersham?
None of the work we do requires planning permission. If your Hersham property is listed or in a conservation area, that affects the roof covering and external alterations rather than insulation laid inside the roof space, though it is always worth mentioning at survey.
Can I still use my Hersham loft for storage afterwards?
Yes, provided the boarding is raised. Screwing boards straight onto 100mm joists over 270mm of wool compresses it to a third of its depth and throws away most of what you paid for. We fit raised boarding on battens so the insulation stays at full depth underneath.
What insulation depth do you fit?
The recommended 270mm, achieved in two layers: the first between the joists, the second laid across them to eliminate the cold bridge through the timber. Skipping that second cross-lay is one of the most common shortcuts in the trade.
Do you offer free surveys in Hersham?
Free, with no call-out fee and no pressure. A meaningful proportion of our Hersham surveys conclude that the loft is already adequately insulated and the homeowner should keep their money — which is a perfectly normal outcome.
