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.

Why book with us in Acton
Tank and pipes protected
Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.
Tidy work
Dust sheets on the route in and every bit of packaging taken away.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.

Questions about a loft insulation top-up in Acton
Do you cover all of W3?
Yes, we cover the W3 postcode district and the districts around Acton.
Can a landlord in Acton book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
Is loft work in Acton 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 new insulation go on top of old insulation?
Yes, if the old layer is dry, clean and reasonably even. If it is damp, contaminated or badly compressed we recommend removing it first.
Is it worth topping up 100 mm of loft insulation?
Often, if the existing layer is in good condition and you also want a warmer house or a better EPC. On bill savings alone, a top-up from about 100 mm takes decades to pay back, so the case is strongest when it is done alongside other loft work.
