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.
- Gaps in the existing layer filled
- Eaves ventilation kept clear

Questions about a loft insulation top-up in Powys
Do you cover the whole of Powys?
Yes. We cover every town and village in Powys, including Brecon, Builth Wells and Llandrindod Wells.
Can you quote for several properties in Powys?
Yes. Landlords and agents can send a list of addresses and we will survey them in as few visits as we can.
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.
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.
