What is a loft insulation top-up?
Before we quote we measure the existing layer in several places and check its condition. If it is wet, dirty, matted or full of droppings, laying fresh wool on top just buries the problem, so we say so and price removal instead. More about a loft insulation top-up.

Questions about a loft insulation top-up in Portishead
Do you charge extra to travel to Portishead?
Not normally. Our guide prices include normal travel to Portishead. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Do you cover all of BS20?

Is loft work in Portishead different from anywhere else?
The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.
Can I still store things in the loft after a top-up?
Not directly on the insulation. A 270 mm layer stands well above the joists, so storage needs raised boarding on loft legs.
Which way should the top-up layer run?
Across the joists, at right angles to the first layer. That covers the tops of the joists, which otherwise let heat escape along the timber.
