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 Chiswick
Clear contact details
Your quote says who to call with questions before, during and after the work.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
Downlights made safe
Fire-rated covers or a clear zone around recessed lights.
Tank and pipes protected
Every insulation job includes a tank jacket and pipe lagging, so nothing freezes in a colder loft.

Questions about a loft insulation top-up in Chiswick
Do you charge extra to travel to Chiswick?
Not normally. Our guide prices include normal travel to Chiswick. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Can a landlord in Chiswick book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
What do I need to do before you arrive in Chiswick?
Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.
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.
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.
