Loft insulation in Feltham
We insulate lofts across Feltham — topping up thin or ageing material to the depth current building regulations recommend, boarding the space so it earns its keep, and fitting proper access so you can actually get to it. Every job starts with a free survey, and every price is fixed before work begins.

Why it matters
The case for insulating your Feltham loft
25%of a home's heat is lost through an uninsulated roof

Put against current energy prices, a Feltham loft still carrying 100mm of settled wool is costing its owner money every single winter it stays that way.
Feltham's homes
Older Feltham homes, modern standards
Feltham's housing stock largely dates from the 1880s through the 1930s, and the roofs above it are typically pitched tile and slate roofs, with hipped ends common on the suburban stock. 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: the 1930s suburban expansion here produced thousands of near-identical semis, which means the same loft problems repeat street after street. We look for that on every Feltham survey.

Five ways we keep Feltham 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 Feltham 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 Feltham lofts should have had first time.
Loft ladders
Fitted in a dayFitted in a day, finished to match your landing, with the hatch insulated and draught-sealed as part of the same job.
Loft makeovers
All-in-oneFor Feltham homeowners who want the roof space to stop being a problem and start being storage: everything, in a day.

Questions & answers
Feltham loft insulation — common questions
How long does the work take in a typical Feltham home?
Half a day for insulation alone; a full day for a combined job with boarding, lighting and a ladder. Very large Feltham lofts or heavy strip-outs occasionally run into a second morning, and we tell you that in advance.
Will insulating my loft cause damp?
Correctly installed, no. The risk comes from packing material hard into the eaves and sealing off the airflow the roof depends on. We stop the insulation short and use eaves trays where the pitch requires them.
Can you fit a loft ladder at the same time?
Yes, and it is cheaper done together. The one thing to check is the hatch: many older Feltham openings are too small for a ladder to swing through safely, so enlargement may be needed. We measure at survey and price it up front. See loft ladders.
What insulation depth do you fit?
Full recommended depth of 270mm as standard. Going deeper gives sharply diminishing returns; stopping short leaves money on the table every winter. For sloping ceilings in Feltham loft rooms, multifoil at around 40mm is the practical alternative.
Do you work in the streets around Feltham?
We do. Coverage extends across Feltham and the neighbouring areas, and we are happy to confirm your specific postcode over the phone before booking anything.
Do I need planning permission in Feltham?
None of the work we do requires planning permission. If your Feltham 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.
