Loft insulation in Woolwich
If your Woolwich loft has 100mm of flattened wool and a boarded patch balanced on the joists, you are not alone and you are losing money every winter. We fit insulation to the recommended 270mm depth, and raise any boarding clear so it keeps working.

Woolwich's homes
What we find in Woolwich roof spaces
The roofs over Woolwich are mostly pitched tile and slate roofs with reasonable head height, and hipped ends on the interwar semis that reduce the usable void, and they were built during the 1880s through the 1930s for a housing market with no expectation of thermal performance. Insulation arrived later, retrofitted into spaces never designed to accommodate it, and the results vary enormously from street to street.
On survey we routinely find the same handful of problems: material compressed to a fraction of its depth by boards laid straight onto the joists, insulation packed hard into the eaves and sealing off the roof's only ventilation path, hatches left as bare uninsulated panels, and recessed downlighters buried under wool. None of these are exotic and all of them are fixable — but they need finding first.
Hipped roofs on 1930s semis cut the usable loft area down sharply at the corners, which changes how much of it is worth boarding, which is one more reason we measure rather than assume.

Five ways we keep Woolwich 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 Woolwich houses still have to a full 270mm is the cheapest meaningful energy improvement available to a UK homeowner.
Loft boarding
Storage-readyBoards laid straight onto joists crush 270mm into 100mm. We batten out instead, so Woolwich homeowners get usable storage and keep the insulation they paid for.
Loft ladders
Fitted in a dayMany older Woolwich hatches are too small for a ladder to swing through safely. We measure at survey and price any enlargement up front rather than on the day.
Loft makeovers
All-in-oneFor Woolwich homeowners who want the roof space to stop being a problem and start being storage: everything, in a day.

Questions & answers
Woolwich loft insulation — common questions
What happens to the water tank and pipes?
Insulating the loft floor makes everything above it colder, including your tank and pipework. Lagging is therefore part of the work rather than an optional extra, and we will point out anything that looks like it will need attention.
Do I need planning permission in Woolwich?
Not for insulation, boarding or a ladder. The line falls at conversion — turning the loft into a habitable room — which is a structural job requiring building control sign-off and a different trade entirely.
Will insulating my loft cause damp?
It can if the ventilation is ignored, which is why we check it before anything comes off the van. If we find an existing condensation problem in a Woolwich loft, we deal with the cause first rather than insulating over it.
