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 dry, even and not contaminated, we keep it and lay the top-up across it at right angles. More about a loft insulation top-up.

Why book with us in Cwmbran
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.
Tidy work
Dust sheets on the route in and every bit of packaging taken away.
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 Cwmbran
How do I pay for work in Cwmbran?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
What do I need to do before you arrive in Cwmbran?
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 loft work in Cwmbran 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.
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.
