Loft insulation in Streatham
Streatham sits in South London, where the housing is dominated by dense Victorian terraces and villas, interwar semis and a substantial amount of purpose-built and converted flats. Much of it was insulated to a standard that has since been superseded twice over. We put that right — properly, in a day, for a price agreed in advance.

Streatham's homes
Older Streatham homes, modern standards
Streatham's housing stock largely dates from the 1860s through the 1930s, and the roofs above it are typically slate and tile pitched roofs, with many terraces running unbroken for a considerable length. Very little of it was built with any insulation at all; what is there now was added later, and its condition depends entirely on who added it and when.
Retrofitted insulation ages in predictable ways. Mineral wool settles and compresses under its own weight over decades. Anything that has been walked on, stored on or boarded over is thinner than it was. Material that has been repeatedly damp has lost most of its value. And the very oldest loose-fill products are often best removed entirely rather than topped over.
A specific local factor: subdivision into flats is very common, so ownership of the roof space is worth establishing before work is booked. We look for that on every Streatham survey.

Five ways we keep Streatham 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 depthTopping up from the 100mm many Streatham houses still have to a full 270mm is the cheapest meaningful energy improvement available to a UK homeowner.
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 Streatham lofts should have had first time.
Loft ladders
Fitted in a dayFixed, stable access instead of a stepladder on the landing. Timber, aluminium or concertina, chosen to suit the space your Streatham home actually has.
Loft makeovers
All-in-oneThe whole loft dealt with at once, for one fixed price. Most Streatham properties are finished within a day.

Questions & answers
Streatham loft insulation — common questions
Do you remove the old insulation?
It depends what is up there. Cross-laying a new layer over sound existing material is both cheaper and perfectly correct. Failed, contaminated or loose-fill material is stripped, bagged and disposed of — slow work, and we show it as its own line on the quote.
How long does the work take in a typical Streatham home?
A straightforward insulation job in a three-bedroom Streatham 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.
